Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0008] Figure 1 This is a structural block diagram of a television set in one embodiment; Figure 2 This is a schematic diagram of the data connector of a SATA interface device in one embodiment; Figure 3 This is a schematic diagram of the power connector of a SATA interface device in one embodiment. Detailed Implementation

[0009] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0010] In one embodiment, a SATA interface device based on a television motherboard is provided. This embodiment uses the application of this device in a television as an example for illustration. Figure 1 As shown, the SATA interface device 101 is integrated into the TV motherboard 102 in the TV 100, and the SATA hard drive 103 built into the TV 100 is connected to the TV motherboard 102 through the SATA interface device 101.

[0011] The SATA interface device 101 represents a device for implementing the Serial Advanced Technology Attachment (SATA) interface, used to establish a channel for data transmission and control signals between the TV motherboard 102 and the SATA hard drive 103, for example, providing physical connection and protocol support for sending and receiving data during video storage and playback.

[0012] Among them, the TV motherboard 102 represents the core circuit board inside the TV 100, which is used to carry functional components such as processor, memory, control chip and input / output interface, and serves as a central platform for data processing and management when performing video playback, data storage and system control.

[0013] Among them, SATA hard drive 103 represents a hard drive storage device that conforms to the Serial Advanced Technology Attached Interface standard, used to receive data transmitted by the TV motherboard 102 and store it or return the stored content to the TV motherboard 102, such as storing recorded program videos in the TV 100 and playing them back when the user needs them.

[0014] For example, the SATA interface device 101 does not connect the TV motherboard 102 and the SATA hard drive 103 via a SATA-USB adapter. Instead, it serves as a data and power interface unit directly connecting the TV motherboard 102 and the SATA hard drive 103, providing a direct connection path compliant with the SATA standard. Essentially, during the design and manufacturing phases of the TV motherboard 102, the electrical pins, transmission channels, and matching circuits related to the SATA interface device 101 are pre-defined and coordinated, allowing the SATA interface device 101 to be stably embedded on the motherboard and directly interface with the SATA port provided by the hard drive. Based on this, the SATA interface device 101 forms a reliable coupling relationship with both the motherboard and the hard drive at the electrical level, eliminating the need for the SATA-to-USB adapter board and USB data cable required in traditional commercial hard drives, reducing additional hardware components. Therefore, the TV motherboard 102 and the SATA hard drive 103 can establish a unified and continuous data and power path through the SATA interface device 101, avoiding unstable contact or signal loss problems caused by adapters, and achieving a more compact and efficient connection method in the overall structure.

[0015] Based on this, the SATA hard drive 103 is not temporarily connected via an external slot, but is set in the internal structure of the TV 100 during the overall design phase, and forms a fixed electrical connection with the TV motherboard 102 through the SATA interface device 101. In other words, the SATA hard drive 103's connection to the motherboard circuit relies on the data and power paths provided by the SATA interface device to achieve a stable interface with the TV motherboard 102. This allows the SATA hard drive 103 to be permanently embedded as part of the TV 100's internal components, avoiding the instability and operational complexity associated with external connections.

[0016] Based on this, through this dual built-in relationship, on the one hand, the SATA interface device 101 is built into the TV motherboard 102 to directly assume the functions originally implemented by the SATA to USB small board and USB data cable; on the other hand, the SATA hard drive 103 is built into the TV 100 and directly connected to the TV motherboard 102 through the SATA interface device 101. Thus, the TV 100 as a whole establishes a simplified and efficient data transmission and storage path, ensuring a stable and unified data interaction and power supply channel at the circuit level, thereby laying a reliable foundation for subsequent video storage and playback operations.

[0017] Furthermore, the SATA interface device 101 includes a first signal line and a second signal line.

[0018] Specifically, one end of the first signal line is connected to the transmitting end of the TV motherboard 102, and the other end is connected to the receiving end of the SATA hard drive 103, so as to provide a transmission path for the TV motherboard 102 to transmit the video data to be stored to the SATA hard drive 103.

[0019] Specifically, one end of the second signal line is connected to the receiving end of the TV motherboard 102, and the other end is connected to the transmitting end of the SATA hard drive 103, so as to provide a transmission path for the SATA hard drive 103 to transmit the stored video data to the TV motherboard 102.

[0020] For example, the first signal line forms a stable transmission path between the transmitting end of the TV motherboard 102 and the receiving end of the SATA hard drive 103. In this transmission path, when the TV motherboard 102 needs to write video data to the SATA hard drive 103, the TV motherboard 102 performs protocol processing on the video data through the SATA interface device 101, making it conform to the data format of the SATA communication protocol, and transmits it to the SATA hard drive 103 through the first signal line. After receiving this data, the SATA hard drive 103 parses the data according to the decoding mechanism of the SATA communication protocol and stores the parsed video data in the disk medium or solid-state storage unit configured on the SATA hard drive 103. Based on this, the first signal line ensures that the data generated on the motherboard side can be successfully transmitted to the hard drive side and ultimately complete the data writing operation, thereby ensuring the continuity and integrity of the storage process.

[0021] For example, the second signal line forms a stable transmission path between the transmitting end of the SATA hard drive 103 and the receiving end of the TV motherboard 102. In this transmission path, the SATA hard drive 103 processes the stored video data according to the protocol, making it conform to the data format of the SATA communication protocol, and transmits it to the SATA interface device 101 via the second signal line. After receiving this data, the SATA interface device 101 parses the data according to the decoding mechanism of the SATA communication protocol and transmits the parsed video data to the TV motherboard 102, so that the TV motherboard 102 transmits the video data to the display interface of the TV 100 for display. Based on this, the second signal line ensures that the data generated on the hard drive side can be successfully transmitted to the motherboard side and ultimately complete the data reading operation, thus ensuring the continuity and integrity of the calling process.

[0022] In this embodiment, on the one hand, based on the direct connection feature of the SATA interface device directly replacing the traditional data transfer structure, efficient connection between the motherboard and the hard drive is achieved at the circuit level. Simultaneously, based on the structural feature of the SATA hard drive being built into the TV, the hard drive and the overall structure are integrated at the physical level, avoiding connection instability and usage complexity caused by external plug-in methods. On the other hand, the transmission path constructed by the first signal line ensures that video data can be transmitted and stably written to the SATA hard drive in a format conforming to the SATA communication protocol. Simultaneously, the transmission path constructed by the second signal line ensures that the video data stored on the SATA hard drive can be transmitted and stably returned to the TV motherboard in a format conforming to the SATA communication protocol. Based on this, in the entire technical solution, the direct connection design of the SATA interface device, the built-in design of the SATA hard drive, and the bidirectional signal line configuration ensure the continuity and stability of data interaction between the motherboard and the hard drive. This achieves efficient storage and playback functions for the TV, improving the convenience of program storage, while also ensuring the hard drive's adaptability and reducing overall configuration costs based on the SATA interface's expandability.

[0023] In one exemplary embodiment, the SATA interface device 101 further includes a data connector having a first signal line pin and a second signal line pin.

[0024] Specifically, the receiving end of the SATA hard drive 103 is connected to the first signal line pin via the first signal line, and the first signal line pin is electrically connected to the transmitting end of the TV motherboard 102; the transmitting end of the SATA hard drive 103 is connected to the second signal line pin via the second signal line, and the second signal line pin is electrically connected to the receiving end of the TV motherboard 102, so as to establish a transmission path between the TV motherboard 102 and the SATA hard drive 103 through the data connector.

[0025] For example, based on the transmission requirements between the TV motherboard 102 and the SATA hard drive 103, the independent pins for data interaction that need to be configured on the data connector are determined in advance, including a first signal line pin and a second signal line pin. Furthermore, to ensure the stability of the electrical connection, these pins can adopt a uniform pin arrangement and have good conductivity in their structure to avoid interference or impedance mismatch during signal transmission. Based on this, the first signal line pin and the second signal line pin become key nodes in the entire data transmission process. That is, through the above settings, the data connector not only provides physical connection points but also provides a standardized interface for subsequent signal line access, ensuring a clear channel division for the connection between the TV motherboard 102 and the SATA hard drive 103.

[0026] Furthermore, the SATA hard drive 103 is provided with a transmitter and a receiver corresponding to the SATA connection. The transmitter and receiver are connected to the data connector 101 through a SATA data cable. The internal cable channels of the SATA data cable correspond to the logical channels of the first signal line and the second signal line, respectively, so that the receiver of the SATA hard drive 103 is connected to the first signal line pin of the data connector through the first signal line, and the transmitter of the SATA hard drive 103 is connected to the second signal line pin of the data connector through the second signal line.

[0027] Furthermore, the TV motherboard 102 is provided with a transmitter and a receiver for video storage. The transmitter and receiver are connected to the data connector 101 through internal wiring of the motherboard. In the internal wiring area of ​​the data connector 101, the transmitter of the TV motherboard 102 is connected to the first signal line pin to access the first signal line, and the receiver of the TV motherboard 102 is connected to the second signal line pin to access the second signal line.

[0028] Optionally, in specific applications, the SATA data cable corresponding to the SATA hard drive 103 can be extended by adding a physical extension section to extend the connection between the motherboard and the hard drive. This means that the SATA hard drive 103 does not necessarily need to be installed flush against the TV motherboard 102. Instead, the TV motherboard 102 and the SATA hard drive 103 can be rationally partitioned according to heat dissipation conditions, mechanical fixing methods, and the layout of the overall structure. Based on this, a stable data interaction path can still be established between the TV motherboard 102 and the SATA hard drive 103 under different layouts, thereby ensuring consistent reliability of data transmission under various installation conditions.

[0029] In this embodiment, on the one hand, the receiving end of the SATA hard drive is connected to the first signal line pin via a first signal line, and this pin is electrically connected to the transmitting end of the TV motherboard, thereby establishing a transmission path from the motherboard to the hard drive. On the other hand, the transmitting end of the SATA hard drive is connected to the second signal line pin via a second signal line, and this pin is electrically connected to the receiving end of the TV motherboard, thereby establishing a transmission path from the hard drive to the motherboard. Based on this, in the entire technical solution, a bidirectional data exchange transmission path is constructed between the motherboard and the hard drive through a data connector, providing clear physical support for the subsequent complete data transmission.

[0030] In one exemplary embodiment, such as Figure 2As shown, the first signal line includes a first differential signal pair (i.e., TXP and TXN), and the second signal line includes a second differential signal pair (i.e., RXN and RXP), for transmitting video data between the TV motherboard 102 and the SATA hard drive 103 in differential signal form.

[0031] Specifically, in the data connector 1011, the first signal line pins include a positive first signal line pin (i.e., pin 2) and a negative first signal line pin (i.e., pin 3). The transmitting end of the SATA hard drive 103 is connected to the positive first signal line pin and the negative first signal line pin respectively through the first differential signal line pair, and the positive first signal line pin and the negative first signal line pin are connected to the transmitting end of the TV motherboard 102 through the internal wiring area of ​​the data connector 1011 respectively.

[0032] Specifically, in the data connector 1011, the second signal line pins include a positive pin (i.e., pin 6) and a negative pin (i.e., pin 5). The receiving end of the SATA hard drive 103 is connected to the positive pin and the negative pin of the second signal line respectively through the second differential signal line pair. The positive pin and the negative pin of the second signal line are connected to the receiving end of the TV motherboard 102 through the internal wiring area of ​​the data connector 1011 respectively.

[0033] For example, the first signal line includes a first differential signal line pair, that is, it is designed to include a pair of differential signal lines, which are composed of two transmission paths of mutually inverted signals, for transmitting data from the TV motherboard 102 to the SATA hard drive 103 in a differential signal format; correspondingly, the second signal line includes a second differential signal line pair, that is, it is designed to include a pair of differential signal lines, which are composed of two transmission paths of mutually inverted signals, for transmitting data from the SATA hard drive 103 to the TV motherboard 102 in a differential signal format.

[0034] Specifically, during actual data transmission, when the TV motherboard 102 needs to output video data, the video data is decomposed into two logically complementary signals and loaded onto the two transmission paths of the first differential signal pair to ensure that the signals can be transmitted in pairs from the transmitting end of the TV motherboard 102 to the receiving end of the SATA hard drive 103. Similarly, when the SATA hard drive 103 needs to transmit stored video data back to the TV motherboard 102, the video data is decomposed into two logically complementary signals and loaded onto the two transmission paths of the second differential signal pair to ensure that the signals can be transmitted in pairs from the transmitting end of the SATA hard drive 103 to the receiving end of the TV motherboard 102.

[0035] Furthermore, the first signal line pins in the data connector 1011 are further divided into a positive pin and a negative pin according to the logic of differential signal transmission, thus forming a one-to-one correspondence with the first differential signal line pair. When the TV motherboard 102 outputs video data, the transmitting end of the TV motherboard 102 transmits the video data to the positive and negative pins of the first signal line in the data connector 1011 through the part of the internal wiring area that is electrically connected to the transmitting end of the TV motherboard 102, thereby loading the video data into the two transmission paths of the first differential signal line pair to form a differential signal; then, according to the connection relationship between the first differential signal line pair and the receiving end of the SATA hard drive 103, the differential signal is transmitted to the receiving end of the SATA hard drive 103. Based on this structure, the first differential signal pair logically establishes a complete path between the TV motherboard 102 and the SATA hard drive 103. The two complementary signals loaded by the data connector 1011 at the transmitting end of the TV motherboard 102 are simultaneously introduced and transmitted through the positive and negative pins of the data connector 1011, and ultimately received by the receiving end of the SATA hard drive 103. Thus, the data connector 1011 not only serves as a physical interface but also logically matches the differential transmission path with the signal port, ensuring that the transmission path represented by the first differential signal pair is actually established in the circuit system structure.

[0036] Furthermore, the second signal line pins in the data connector 1011 are further divided into a positive pin and a negative pin according to the logic of differential signal transmission, thus forming a one-to-one correspondence with the second differential signal line pair. When the SATA hard drive 103 outputs video data, its transmitting end loads the video data into the two transmission paths of the second differential signal line pair to form a differential signal. These two transmission paths are respectively connected to the positive pin and the negative pin of the second signal line in the data connector 1011, thereby transmitting the differential signal to the data connector 1011. Then, through the portion of the internal wiring area of ​​the data connector 1011 that is electrically connected to the receiving end of the TV motherboard 102, the differential signal is transmitted to the receiving end of the TV motherboard 102. Based on this structure, the second differential signal pair logically establishes a complete path between the SATA hard drive 103 and the TV motherboard 102. The two complementary signals loaded at the transmitting end of the SATA hard drive 103 are simultaneously introduced and transmitted through the positive and negative pins of the data connector 1011, and are ultimately received by the transmitting end of the TV motherboard 102. Thus, the data connector 1011 not only serves as a physical interface but also logically matches the differential transmission path with the signal port, ensuring that the transmission path represented by the second differential signal pair is actually established in the circuit system structure.

[0037] For example Figure 2 As shown, a coupling capacitor C1 is configured on the TXP line, a coupling capacitor C2 is configured on the TXN line, a coupling capacitor C3 is configured on the RXN line, and a coupling capacitor C4 is configured on the RXP line. This is to avoid inconsistency in the DC bias level between the motherboard and the hard drive, prevent DC surges, and allow both sides to establish their own common-mode voltage.

[0038] In this embodiment, on the one hand, the first signal line and the second signal line are respectively divided into differential signal line pairs, thereby establishing paired transmission paths for bidirectional transmission of video data; on the other hand, the pins of the first signal line are divided into positive and negative terminals to match the first differential signal line pairs, and connected to the transmitting end of the TV motherboard through the internal wiring of the data connector; and the pins of the second signal line are divided into positive and negative terminals to match the second differential signal line pairs, and connected to the receiving end of the TV motherboard through the internal wiring of the data connector, thereby ensuring the integrity and accuracy of the data transmission process between the hard drive and the motherboard. Based on this, in the entire technical solution, a bidirectional differential signal transmission path is formed between the TV motherboard and the SATA hard drive, making the data exchange process have a clear channel division and a traceable connection relationship.

[0039] In one exemplary embodiment, for example... Figure 2As shown, the data connector 1011 also has a first ground pin (i.e., pin 1), a second ground pin (i.e., pin 4) and a third ground pin (i.e., pin 7), and each ground pin is grounded.

[0040] Specifically, a positive terminal pin and a negative terminal pin of a first signal line are provided between the first grounding pin and the second grounding pin; a positive terminal pin and a negative terminal pin of a second signal line are provided between the second grounding pin and the third grounding pin.

[0041] Specifically, the first grounding pin is used to suppress external interference received by the first differential signal line pair, the second grounding pin is used to suppress crosstalk between the first differential signal line pair and the second differential signal line pair, and the third grounding pin is used to suppress external interference received by the second differential signal line pair.

[0042] For example, in addition to pins for signal transmission, the data connector 1011 further includes a first ground pin, a second ground pin, and a third ground pin. Each ground pin is connected to a ground wire through circuit design to maintain a stable grounding state during use. In a specific implementation, the positive and negative pins of the first signal line of the first differential signal pair are arranged between the first ground pin and the second ground pin. Correspondingly, the positive and negative pins of the second signal line of the second differential signal pair are arranged between the second ground pin and the third ground pin. This layout allows the two pins of the differential signal pair to be connected under the clamping of a pair of ground pins. That is, the data connector 1011 not only provides access points for signal lines but also, through the reasonable arrangement of ground pins and signal pins, enables the signal line pair to have an independent and controlled transmission path at the structural level.

[0043] Furthermore, based on the above, the first, second, and third grounding pins do not merely exist as physical grounding points, but rather, in different relative positions, they serve to suppress interference along the signal line transmission path. In specific implementation, since the first grounding pin is located outside the positive and negative pin groups of the first signal line, it provides shielding for the corresponding differential signal pairs, allowing external electromagnetic interference to be preferentially absorbed and discharged by the grounding pin when it approaches the signal pairs, thereby reducing external influences on the signal. Since the second grounding pin is located between the positive and negative pin groups of the first and second signal lines, it provides isolation for the two differential signal pairs, preventing direct interaction when the two differential signal pairs are spatially adjacent, thus reducing crosstalk between them. Since the third grounding pin is located outside the positive and negative pin groups of the second signal line, it provides shielding for the corresponding differential signal pairs, allowing external electromagnetic interference to be preferentially absorbed and discharged by the grounding pin when it approaches the signal pairs, thereby reducing external influences on the signal.

[0044] In addition, pins 8 and 9 of the data connector 1011 are also ground pins, so that the entire signal range of the data connector 1011 is surrounded by ground pins, which helps to form a more complete shielding layer and reduce the coupling of external electromagnetic interference to the internal high-speed signal lines.

[0045] In this embodiment, the three-point grounding arrangement and the coordinated arrangement of the grounding pins and signal pins ensure that the first differential signal line pair and the second differential signal line pair have independent protection channels inside the data connector. Each group of signal lines is within the constraint range of the grounding pins, which not only isolates them from each other at the structural level, but also ensures stable signal transmission at the electrical performance level.

[0046] In one exemplary embodiment, such as Figure 3 As shown, the SATA interface device 101 also includes a power connector 1012, which includes a positive power terminal (i.e., pin 1) and a negative power terminal (i.e., pin 2).

[0047] Specifically, the positive terminal of the SATA hard drive 103 is connected to the positive terminal of the power supply, the negative terminal of the SATA hard drive 103 is connected to the negative terminal of the power supply, and the negative terminal corresponds to the ground terminal. The positive and negative terminals are respectively connected to the two ends of the preset filter capacitor C5. The power supply terminals of the TV motherboard 102 are respectively connected to the positive and negative terminals of the power supply to provide 5V operating power to the SATA hard drive 103 through the power connector 1012.

[0048] For example, the positive terminal of the SATA hard drive 103 is fixedly connected to the positive power terminal of the power connector 1012 via a wire, ensuring that the SATA hard drive 103 can receive the power voltage provided by the TV motherboard 102. Simultaneously, the negative terminal of the SATA hard drive 103 is connected to the negative power terminal of the power connector 1012 via another wire. This negative terminal corresponds to the ground terminal in the circuit, thus forming a current loop. Furthermore, to ensure a stable power supply to the SATA hard drive 103 during operation, a filter capacitor C5 is placed between the positive and negative power terminals. One end of the filter capacitor C5 is connected to the positive power terminal, and the other end is connected to the negative power terminal, thus forming a parallel branch in the power path. Based on this, when the positive and negative power terminals are connected to the SATA hard drive 103 respectively, the capacitor C5 filters the voltage at both ends, absorbing voltage fluctuations during power transients or when interference is present, making the voltage received by the SATA hard drive 103 more stable.

[0049] Furthermore, the power supply voltage output from the power module of the TV motherboard 102 is connected to the positive and negative terminals of the power connector 1012 through the internal wiring area of ​​the power connector 1012. The positive terminal directly receives a stable voltage from the motherboard power line, while the negative terminal is connected to the motherboard's common ground line, thus enabling the power connector 1012 to supply power to the SATA hard drive 103. Essentially, during the design phase, the motherboard circuitry has reserved an electrical path with the power connector 1012, and through reasonable wiring planning, ensures low impedance and low loss in the power supply path. Therefore, when the motherboard power is transmitted to the hard drive through the power connector 1012, the hard drive can obtain the same electrical reference environment as the internal circuitry of the motherboard, avoiding voltage differences or electrical inconsistencies caused by external power supply methods. Thus, the SATA interface device 101 not only realizes the signal interaction connection function but also completes the power supply path construction through the power connector 1012, thereby establishing a complete connection relationship between the hard drive and the motherboard that includes both data signal transmission and power transfer.

[0050] In this embodiment, on the one hand, the positive terminal of the SATA hard drive is connected to the positive terminal of the power supply, and the negative terminal of the SATA hard drive is connected to the negative terminal of the power supply. A filter capacitor is connected in parallel between the two ends to ensure that the SATA hard drive receives a complete power input and has voltage stabilization measures in the power supply path. On the other hand, the power supply terminals of the TV motherboard are connected to the positive and negative terminals of the power supply respectively, so that the motherboard power supply directly supplies power to the hard drive and maintains a unified electrical reference. Based on this, in the entire technical solution, through the configuration of the power connector and the filter capacitor, a complete and stable power supply path is formed between the motherboard and the hard drive, laying a reliable foundation for the continuous operation of the hard drive.

[0051] Based on the same inventive concept, this application also provides a television for implementing the aforementioned SATA interface device based on a television motherboard. The solution provided by this television is similar to the solution described in the aforementioned device; therefore, the specific limitations in one or more television device embodiments provided below can be found in the above-described limitations regarding the SATA interface device based on a television motherboard, and will not be repeated here.

[0052] In one exemplary embodiment, such as Figure 1 As shown, a television set 100 is provided. The television set 100 includes a SATA interface device 101, a television motherboard 102 and a SATA hard drive 103 as described in any of the above embodiments. The SATA interface device 101 is integrated into the television motherboard 102, and the SATA hard drive 103 built into the television set 100 is connected to the television motherboard 102 through the SATA interface device 101.

[0059] In one exemplary embodiment, the TV motherboard 102 establishes a wireless communication connection with a preset remote control and receives control commands from the remote control.

[0060] On one hand, when the control command from the remote control is a store command, the TV motherboard 102 uses the video data currently displayed on the TV 100 as the video data to be stored, and transmits it to the SATA hard drive for storage via the first signal line in the SATA interface device 101. On the other hand, when the control command from the remote control is a stop store command, the TV motherboard 102 interrupts the data transmission on the first signal line.

[0061] For example, the TV motherboard 102 first establishes a wireless communication connection with a preset remote control. When the remote control issues a control command and the TV motherboard 102 receives it, the TV motherboard 102 parses the control command and triggers corresponding operation logic based on its content. When the parsing result is a storage command, the TV motherboard 102 determines the video data currently displayed on the TV 100 as the video data to be stored. Based on this, the TV motherboard 102 encapsulates the video data to conform to the data signal format that the SATA interface device 101 can recognize and transmit. Subsequently, the TV motherboard 102 loads the processed data onto the first differential signal pair through an electrical connection with the SATA interface device 101, and transmits it to the receiving end of the SATA hard drive 103 through the first differential signal pair. Finally, after receiving this data, the SATA hard drive 103 decapsulates it into corresponding video data and stores it step by step according to its internal writing logic, thereby storing the video data in a disk medium or solid-state storage unit.

[0062] Furthermore, when the parsing result is a stop storage instruction, the TV motherboard 102 controls its output drive circuit to stop loading new data onto the first differential signal line pair, thereby preventing the SATA interface device 101 from transmitting video data to the SATA hard drive 103. Simultaneously, the TV motherboard 102 clears the unsent data queue in its internal buffer unit, ensuring that the data transmission interruption is complete and leaves no residue. Therefore, when the receiving end of the SATA hard drive 103 detects a data transmission interruption, it automatically completes the writing of the current data block and terminates the current storage task. In this way, the storage process is orderly closed on both the motherboard and the hard drive, avoiding data loss or storage damage caused by forced power outages or abnormal interruptions.

[0063] Optionally, when the motherboard receives a storage command, it does not write the entire video stream continuously. Instead, it divides the video stream into data segments with logical markers. Each data segment contains start and end index information and a checksum field, and these segments are transmitted sequentially to the hard drive for storage. When a stop storage command is received, the motherboard terminates the transmission after the current data segment is written and automatically generates an end marker for that data segment on the hard drive. Thus, each storage operation and storage stop operation leaves a recognizable segment marker on the hard drive. Subsequently, during playback or secondary storage, the motherboard can use these segment markers to trace and reassemble the data, enabling continuous management and retrieval of multiple stored contents.

[0064] In this embodiment, firstly, after receiving the storage instruction, the TV motherboard transmits the currently displayed video data as the data to be stored to the SATA hard drive via the first signal line, thereby ensuring that the real-time displayed content can be synchronously converted into storage data on the hard drive. Secondly, after receiving the stop storage instruction, the TV motherboard interrupts the transmission of data on the first signal line, thereby ensuring that the storage process can be terminated in an orderly manner and avoiding data corruption. Based on this, in the entire technical solution, by parsing the control instructions of the remote control and controlling the signal transmission path, the complete conversion from video display to video storage and the safe termination of the storage process are realized, thus forming a controlled and stable data storage solution.

[0065] In one exemplary embodiment, the TV motherboard 102 establishes a wireless communication connection with a preset remote control and receives control commands from the remote control.

[0066] On the one hand, when the control command from the remote control is a storage list command, the TV motherboard 102 is used to read the description information corresponding to each video data stored in the SATA hard disk 103 through the second signal line in the SATA interface device 101, and integrate the description information into a storage list for display on the display interface of the TV 100. On the other hand, when the control command from the remote control is a playback command, the TV motherboard 102 selects the target video data to be played from the storage list and reads the target video data from the SATA hard drive 103 through the second signal line to display it on the display interface.

[0067] For example, when a control command issued by the remote control is parsed as a storage list command, the TV motherboard 102 initiates its internal data reading logic to extract descriptive information corresponding to the stored video data from the SATA hard drive 103 via the second differential signal line. The video data stored in the SATA hard drive 103 typically includes a file header or descriptive fields during writing. This descriptive information records the basic attributes of the video data, such as storage location, duration, size, and generation time. Therefore, the TV motherboard 102 does not directly extract the entire video data; instead, it retrieves this descriptive information from the SATA hard drive 103 and collects it one by one. Subsequently, the TV motherboard 102 integrates this descriptive information to form a storage list that the user can browse. This storage list is not merely a simple data set but a processed, graphically generated content that can be presented in an orderly manner on the TV 100's display interface. Thus, when using the remote control, the user can intuitively see the existing video resources on the hard drive without needing to open and confirm each file individually, thereby gaining an overall overview of the video data on the hard drive.

[0068] Furthermore, when the control command issued by the remote control is interpreted as a playback command, the TV motherboard 102 first determines the target video data to be played based on the user's selection in the storage list, and generates a request to call the SATA hard drive 103. Subsequently, the TV motherboard 102 establishes a data return path with the SATA hard drive 103 through the second differential signal line pair in the SATA interface device 101, and reads the target video data from the SATA hard drive 103 step by step according to the call request. In addition, in order to ensure that the video data can be played smoothly on the display interface, the TV motherboard 102 calls the internal buffer unit when receiving data, first stores the data stream returned from the hard drive into the buffer area, and then transmits it to the video decoding unit at a stable rate; the video data after decoding is converted into an image signal that can be directly driven by the display screen, and finally output on the display interface of the TV 100.

[0069] Optionally, when generating the storage list, in addition to reading the basic description information of existing videos on the hard drive, the motherboard further processes this description information to form an extended structure with hierarchical indexes and tags. Specifically, while calling the description information of the stored video data, the motherboard adds additional tag fields to each video data according to preset classification rules, such as grouping by time sequence, source channel, and program type. Simultaneously, the motherboard performs structured processing on the description information, converting it into a hierarchical index table, allowing the same video data to correspond to multiple different search entries. Based on this, the storage list is presented in the display interface not only as a regular directory but also displays tags and group indexes, allowing users to quickly browse and select files from different classification perspectives using a remote control.

[0070] In this embodiment, firstly, after receiving the storage list instruction, the TV motherboard reads the description information of each video data in the SATA hard drive through the second signal line and integrates it into a storage list, so that the content stored on the hard drive can be presented on the display interface in an orderly manner. Secondly, after receiving the playback instruction, the TV motherboard reads the corresponding target video data in the hard drive through the second signal line according to the selection result in the storage list, so that the user can directly retrieve and play the required video file. Based on this, in the entire technical solution, by listing and organizing the video data stored on the hard drive and accurately retrieving the target video data, a complete closed loop of video data from storage, retrieval to playback is realized, improving the orderliness of data retrieval and the convenience of use.
