Description

Technical Field

[0001] This disclosure relates to the field of display device technology, and in particular to a display device and an image frame display method. Background Technology

[0002] Traditional surround sound systems require audio to be transmitted from the source to the speaker, and then the sound is emitted from the speaker. Because the transmission from the source to the speaker involves wired transmission, decoding, and wireless transmission, and both wired and decoding processes have time delays, coupled with the time delay in wireless transmission, a desynchronization can occur between the displayed image at the source and the final sound output from the speaker.

[0003] Therefore, there is an urgent need for a display device and image frame display method that can synchronize the display image at the audio source with the sound output at the final audio source, thereby improving the user experience. Summary of the Invention

[0064] To make the objectives and implementation methods of this disclosure clearer, the exemplary embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this disclosure. Obviously, the exemplary embodiments described are only some embodiments of this disclosure, and not all embodiments.

[0065] It should be noted that the brief descriptions of terms in this disclosure are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this disclosure. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0066] The terms "first," "second," "third," etc., used in this disclosure, in the specification, claims, and accompanying drawings are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0067] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0068] The display device provided in this disclosure can have various implementation forms, such as a television, a smart television, a laser projection device, a monitor, an electronic bulletin board, an electronic table, etc. Figure 1 and Figure 2 This is one specific embodiment of the display device disclosed herein.

[0069] Figure 1 This is a schematic diagram illustrating an operational scenario between a display device and a control device according to an embodiment. Figure 1 As shown, the user can operate the display device 200 through the smart device 300 or the control device 100.

[0070] In some embodiments, the control device 100 may be a remote control. Communication between the remote control and the display device includes infrared protocol communication, Bluetooth protocol communication, and other short-range communication methods, controlling the display device 200 wirelessly or via wired means. Users can control the display device 200 by inputting user commands through buttons on the remote control, voice input, control panel input, etc.

[0071] In some embodiments, a smart device 300 (such as a mobile terminal, tablet computer, computer, laptop computer, etc.) may also be used to control the display device 200. For example, an application running on the smart device may be used to control the display device 200.

[0072] In some embodiments, the display device may receive instructions not through the aforementioned smart devices or control devices, but through touch or gestures.

[0073] In some embodiments, the display device 200 can also be controlled in ways other than the control device 100 and the smart device 300. For example, it can be controlled by directly receiving the user's voice commands through a module configured inside the display device 200 for acquiring voice commands, or it can be controlled by receiving the user's voice commands through a voice control device set outside the display device 200.

[0074] In some embodiments, the display device 200 also communicates with the server 400. The display device 200 may communicate via a local area network (LAN), wireless local area network (WLAN), and other networks. The server 400 may provide various content and interactive features to the display device 200. The server 400 may be a cluster or multiple clusters, and may include one or more types of servers.

[0075] Figure 2 This is a configuration block diagram of a control device according to an embodiment. Figure 2 As shown, the control device 100 includes a controller 110, a communication interface 130, a user input / output interface 140, a memory, and a power supply. The control device 100 can receive user input operation commands and convert the operation commands into commands that the display device 200 can recognize and respond to, thus acting as an intermediary for interaction between the user and the display device 200.

[0076] Figure 3 This is a structural diagram of a display device, a wired audio signal control device, and a wireless audio signal control device in related technologies.

[0077] In one example, display device 200 is connected to host device 900, and display device 200 is used to generate raw audio signals and image frames. Host device 900 can be used to control wired audio signal control device 500 and wireless audio signal control device 600. In this embodiment, host device 900, wired audio signal control device 500, and wireless audio signal control device 600 can jointly form an audio control system. This audio control system can be placed in a vehicle or indoors. Display device 200 sends raw audio signals to host device 900, host device 900 sends raw audio signals to wired audio signal control device 500, and host device 900 sends raw audio signals to wireless audio signal control device 600.

[0078] In some examples, the display device 200 sends the original audio signal to the host 900, resulting in a certain transmission time for the original audio signal. At this time, the original audio signal in the host 900 is out of sync with the image frame of the display device 200.

[0079] During the process of the host 900 sending the original audio signal to the wired audio signal control device 500, there is a certain transmission time. Therefore, there is a greater time delay between the original audio signal output by the wired audio signal control device 500 and the image frame of the display device 200.

[0080] During the process of the host 900 sending the original audio signal to the wireless audio signal control device 600, there is also a certain transmission time. Therefore, there is a greater time delay between the original audio signal output by the wireless audio signal control device 600 and the image frame of the display device 200.

[0081] Furthermore, because the time when the host 900 sends the original audio signal to the wired audio signal control device 500 differs from the time when the host 900 sends the original audio signal to the wireless audio signal control device 600, the timing of the original audio signal output by the wired audio signal control device 500 also differs from the timing of the original audio signal output by the wireless audio signal control device 600. This results in audio-visual desynchronization, as well as asynchronous sound from each audio control device.

[0082] In this embodiment, network data information 800 can also be sent to host 900. The network data information 800 can be the original audio signal obtained from the network, and then sent by host 900 to wired audio signal control device 500 and wireless audio signal control device 600.

[0083] Figure 4 This is a schematic diagram of another connection structure between display devices, wired audio signal control devices, and wireless audio signal control devices in related technologies. Figure 4 The illustration shows that in related technologies, display device 200, wired audio signal control device 500, and wireless audio signal control device 600 are electrically connected in sequence. In this illustration, wired audio signal control device 500 is used to relay the original audio signal. Figure 4 It can be seen that there is a time delay A in the transmission of the original audio signal from the display device 200 to the wired audio signal control device 500, and then from the wired audio signal control device 500 to the wireless audio signal control device 600. Because there is a time delay in the transmission of the original audio signal from the display device 200 to the wired audio signal control device 500, and then another time delay in the transmission from the wired audio signal control device 500 to the wireless audio signal control device 600, these time delays are superimposed. Therefore, a time delay A exists between the original audio signal output by the wireless audio signal control device 600 and the image frame displayed by the display device 200.

[0084] Figure 5 This is a schematic diagram of the structure of a display device provided in some embodiments of this disclosure. For details, please refer to the following description:

[0085] In some examples, display 2001 is configured to receive image frames;

[0086] In some examples, the image frame is an image corresponding to the video stream, where the image frame changes over time.

[0087] In some examples, processor 2002 is configured to acquire the first time value of an image frame as it is received by the display.

[0088] In some examples, an image frame may include image frame A and image frame B. However, image frame A and image frame B are used for illustrative purposes only and do not necessarily include only image frame A and image frame B.

[0089] For better illustration, the first time value when the display 2001 receives an image frame is denoted as T0. Further, the first time value when the display receives image frame A is denoted as T0A, and the next image frame after image frame A is image frame B; therefore, the first time value when the display receives image frame B is denoted as T0B.

[0090] In some examples, the processor 2002 is also configured to: send a first audio signal; wherein the first audio signal is received by a wired audio signal control device 500; the first audio signal is decoded within the wired audio signal control device 500 to obtain first decoded data information; the number of wired audio signal control devices 500 is at least one; and the decoding time of the first audio signal within the wired audio signal control device 500 is a wired decoding time value.

[0091] In some examples, the first audio signal is an audio signal adapted to the wired audio signal control device 500. This first audio signal does not need to be decoded by the processor 2002; instead, it is sent by the processor 2002 to the wired audio signal control device 500, where the device decodes it. This setup reduces processor memory usage and overall processor utilization, allowing the processor to process other signals or data.

[0092] In this embodiment, if there are multiple wired audio signal control devices 500, the first audio signal needs to be sent to each of the wired audio signal control devices 500. In this embodiment, the wired decoding time value is denoted as T1. For a clearer explanation of this embodiment, please refer to [link to relevant documentation]. Figure 6 This diagram illustrates a method for determining wired decoding time values.

[0093] In some examples, the processor 2002 is further configured to: decode the second audio signal to obtain second decoded data information, and send the second decoded data information; wherein the second decoded data information is received by a wireless audio signal control device 600; the number of wireless audio signal control devices 600 is at least one; and the decoding time of the second audio signal within the wireless audio signal control device 600 is a wireless decoding time value.

[0094] In some examples, the second audio signal is an audio signal adapted to the wireless audio signal control device 600. The second audio signal is decoded in the processor 2002 instead of in the wireless audio signal control device 600 because adding a decoder to the wireless audio signal control device 600 would increase costs. The display device 200 generally has decoding capabilities. Therefore, decoding the second audio signal in the processor 2002 can save costs.

[0095] In some examples, if the number of wireless audio signal control devices 600 is at least one, then the second decoded data information needs to be sent to each wireless audio signal control device 600. In this embodiment, the wireless decoding time value is denoted as T2. For a clearer explanation of this embodiment, please refer to [link to relevant documentation]. Figure 7 The diagram illustrates a method for determining wireless decoding time values.

[0096] In some examples, the processor 2002 is also configured to: acquire a second time value and a third time value; wherein the second time value is used to characterize the transmission time of the first audio signal from the processor 2002 to the wired audio signal control device 500; and the third time value is used to characterize the transmission time of the second decoded data information from the processor 2002 to the wireless audio signal control device 600.

[0097] In some examples, for clarity, the second time value can be denoted as T3 and the third time value as T4.

[0098] In some examples, processor 2002 is also configured to determine the display time value based on the wired decoding time value, the wireless decoding time value, the second time value, and the third time value.

[0099] In some examples, the display time value T5 is determined using the wired decoding time value T1, the wireless decoding time value T2, the second time value T3, and the third time value T4. The display time value T5 is used to display image frames on the display 2001. For a clearer explanation of this embodiment, please refer to [link to relevant documentation]. Figure 8 This is a schematic diagram of a display showing an image frame.

[0100] In some examples, processor 2002 is also configured to transmit the display time value to display 2001.

[0101] In some examples, after determining the display time value T5, the processor 2002 transmits the display time value T5 to the display 2001.

[0102] In some examples, the display 2001 is also configured to display image frames based on display time values.

[0103] In some examples, the time when the display 2001 originally displays the image frame is the first time value T0. Due to the delay in the audio signal transmission process, it is necessary to adjust the time when the image frame is displayed on the display 2001. In this case, the time is adjusted from the first time value T0 to the display time value T5.

[0104] In some examples, the processor 2002 is also configured to determine a fourth time value based on the wired decoding time value and the second time value; wherein the fourth time value is used to characterize the duration for which the first audio signal is sent by the processor 2002 to the wired audio signal control device 500 and output by the wired audio signal control device 500.

[0105] In some examples, the fourth time value can be denoted as T6, and the fourth time value can be the sum of the wired decoding time value T1 and the second time value T3. That is, T6 = T1 + T3. For a clearer explanation of this embodiment, please refer to [link to relevant documentation]. Figure 9 A schematic diagram illustrating the determination of a fourth time value is shown.

[0106] A fifth time value is determined based on the wireless decoding time value and the third time value; wherein, the fifth time value is used to characterize the total duration of the second audio signal being received by the processor 2002, sent to the wireless audio signal control device 600, and output by the wireless audio signal control device 600.

[0107] In some examples, the fifth time value can be denoted as T7, and the fifth time value can be the sum of the wireless decoding time value T2 and the third time value T4. That is, T7 = T2 + T4. For a clearer explanation of this embodiment, please refer to [link to relevant documentation]. Figure 10 A schematic diagram illustrating the determination of a fifth time value is shown.

[0108] Based on the fourth and fifth time values, a compensation time value is determined; wherein, the compensation time value is used to determine the time when the image frame is displayed on the display 2001.

[0109] In some examples, the compensation time value can be denoted as T8.

[0110] In some examples, processor 2002 is also configured to compare the values ​​of the fourth time value and the fifth time value, and use the larger value as the compensation time value.

[0111] In some examples, the values ​​of T6 and T7 are compared. For example, if the value of T6 is 10 seconds and the value of T7 is 20 seconds, then the value of T7 is greater than the value of T6. The value of T7 is then used as the compensation time value T8, and the compensation time value T8 is 20 seconds.

[0112] In some examples, processor 2002 is also configured to: compare the values ​​of a fourth time value and a fifth time value, and determine the larger value as the alignment time value; and use the value greater than the alignment time value as the compensation time value.

[0113] In some examples, the values ​​of T6 and T7 are compared. For instance, if T6 is 10 seconds and T7 is 20 seconds, then T7 is greater than T6. T7 is used as the alignment time value T9, and the value greater than T9 is used as the compensation time value T8. For example, if T9 is 30 seconds, then the compensation time value T8 is 30 seconds.

[0114] In some examples, the processor 2002 is also configured to determine a display time value based on a compensation time value and a first time value; wherein the display time value is used to characterize the time for the display to show an image frame.

[0115] In some examples, the displayed time value T5 is the sum of the compensation time value T8 and the first time value T0, i.e., T5 = T8 + T0.

[0116] In some examples, the processor 2002 is also configured to: send a first detection signal to a wired audio signal control device and determine a first transmission time value of the first detection signal; receive a first reception time value from the wired audio signal control device; and determine a second time value based on the first transmission time value and the first reception time value; wherein the first reception time value is used to characterize the time when the wired audio signal control device receives the first detection signal; and wherein the first reception time value is sent to the processor by the wired audio signal control device.

[0117] In some examples, the processor 2002 is also configured to: acquire first identification information of the wired audio signal control device; locate the device associated with the first identification information within a first preset range; and, after identification, send a first detection signal to the wired audio signal control device.

[0118] In some examples, the first identifier is a character string of a preset length, such as AAAAAA. The first preset range can be a preset distance range, such as within 5 meters.

[0119] In some examples, see Figure 11 A schematic diagram illustrating the determination of a second time value is shown.

[0120] In some examples, the processor 2002 is further configured to: send a second detection signal to a wireless audio signal control device and determine a second transmission time value of the second detection signal; receive a second reception time value from the wireless audio signal control device; and determine a third time value based on the second transmission time value and the second reception time value; wherein the second reception time value characterizes the time at which the wireless audio signal control device receives the second detection signal; and wherein the second reception time value is sent to the processor by the wireless audio signal control device. See also [examples omitted for brevity]. Figure 12a A schematic diagram illustrating the determination of a third time value is shown.

[0121] In some examples, the processor 2002 is also configured to: acquire second identification information of the wireless audio signal control device; locate the device associated with the second identification information within a second preset range; and, after identification, send a second detection signal to the wireless audio signal control device.

[0122] In some examples, the second identifier is a character string of a preset length, such as BBBBB. The first identifier differs from the second identifier. The second preset range can be a range greater than the first preset range, for example, within 30 meters. This is because the wireless transmission distance is less restricted.

[0123] In some examples, display device 200 also includes:

[0124] Selector 2003 is configured to: acquire the original audio signal, process the original audio signal, and obtain the first audio signal and the second audio signal.

[0125] In some examples, the first audio signal can be the original audio signal, and the second audio signal can also be the original audio signal. Specifically, the process involves copying the original audio signal into the first and second audio signals before sending them to the processor 2002. For details, please refer to... Figure 12b A schematic diagram of the structure of a display device is shown.

[0126] In some examples, the wired decoding time value may be the same as or different from the wireless decoding time value.

[0127] In some examples, if the wired decoding time value T1 differs from the wireless decoding time value T2, the above process can be followed. If the wired decoding time value T1 and the wireless decoding time value T2 are the same, the above process can be simplified by determining the relationship between T3 and T4, and then determining the compensation time value T8 based on the relationship between T3 and T4.

[0128] In some examples, the first audio signal can also be decoded within the processor 2002 to obtain third decoded data information, which is then sent; wherein, the third decoded data information is received by the wired audio signal control device 500. Specifically, the decoding time of the first audio signal within the processor 2002 is denoted as the first processing time value Tf. In this embodiment, if the difference between the data volume of the third decoded data information and the data volume of the first audio signal is ignored, the transmission time of the third decoded data information from the processor 2002 to the wired audio signal control device 500 is denoted as the second time value T3.

[0129] In this configuration, the processor 2002 is further configured to: decode the second audio signal to obtain second decoded data information, and send the second decoded data information; wherein the second decoded data information is received by a wireless audio signal control device 600; the number of wireless audio signal control devices 600 is at least one; and the decoding time of the second audio signal within the wireless audio signal control device 600 is the wireless decoding time value. In this embodiment, the wireless decoding time value is denoted as T2. The third time value T4 represents the transmission time of the second decoded data information from the processor 2002 to the wireless audio signal control device 600.

[0130] In some examples, the fifth time value can be denoted as T7, which can be the sum of the wireless decoding time value T2 and the third time value T4. That is, T7 = T2 + T4.

[0131] In some examples, the sum of Tf and T3 can be calculated, and the relationship between this sum and the value of T7 can be compared, and the compensation time value T8 can be determined based on this relationship.

[0132] In some examples, the first audio signal can also be decoded within the processor 2002 to obtain third decoded data information, which is then sent; wherein, the third decoded data information is received by the wired audio signal control device 500. Specifically, the decoding time of the first audio signal within the processor 2002 is denoted as the first processing time value Tf. In this embodiment, if the difference between the data volume of the third decoded data information and the data volume of the first audio signal is ignored, the transmission time of the third decoded data information from the processor 2002 to the wired audio signal control device 500 is denoted as the second time value T3.

[0133] In this configuration, the processor 2002 is further configured to transmit a second audio signal, which is received by the wireless audio signal control device 600 and decoded by the wireless audio signal control device 600 to obtain fourth decoded data information. It is worth noting that, at this point, a wireless controller needs to be added to the wireless audio signal control device 600. This wireless controller is used to decode the second audio signal to obtain the fourth decoded data information.

[0134] In this embodiment, the decoding time value of the second audio signal in the wireless audio signal control device 600 is denoted as the second processing time Tg. If the difference between the amount of data of the second decoded data information and the amount of data of the second audio signal is ignored, the third time value T4 represents the transmission time value of the second audio signal sent from the processor 2002 to the wireless audio signal control device 600.

[0135] In some examples, the sum of Tf and T3 can be calculated and compared with the sum of Tg and T4 to obtain the comparison result. Based on the comparison result, the compensation time value T8 can be determined.
