[0017] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] The following will provide a detailed description of the implementation method of the present invention in conjunction with the drawings. What is described is only part of the embodiments, not all embodiments. For the purpose of clarity, the representations and descriptions unrelated to the present invention are omitted in the drawings and the description.

[0019] In order to have a clearer understanding of the technical features, objectives, and beneficial effects of the present invention, the following will provide a detailed description of the technical solutions of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all embodiments, and should not be construed as limiting the scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0020] As Figure 1 shown, the present invention provides a multi-functional intelligent set-top box, including a core processor module 4, a signal receiving and processing module 3, a storage module 6, a sensor module 5, a display output module 7, and an interface module; the interface module specifically includes: a signal input interface 2 and a signal output interface 8.

[0021] Multiple signal sources 1 are transmitted to the signal receiving and processing module 3 through the signal input interface 2, and then transmitted by the signal receiving and processing module 3 to the core processor module 4; the sensor module 5 transmits the data information to the core processor module 4 after sensing information; the core processor module 4 processes the incoming signal data and then transfers and stores it in the storage module 6; the display output module 7 receives the signal data in the storage module 6 and transmits it through the signal output interface 8.

[0022] The signal input interface 2 specifically includes: a cable TV signal interface, a satellite TV signal interface, and an Internet TV signal interface.

[0023] There is a signal processing chip in the signal receiving and processing module 3; the signal processing chip performs adaptive demodulation and decoding, unifies different signal formats for processing, performs signal optimization and signal enhancement operations on the signal, and seamlessly switches the signal sources.

[0024] Adaptive demodulation and decoding has a multi-standard demodulator, supports multiple modulation methods (such as QAM-256 for cable TV, QPSK / DVB-S2 for satellite signals, OFDM for terrestrial broadcasts), and dynamically matches the physical layer protocol of the signal source; at the same time, it has an intelligent decoding engine that can automatically identify compression formats (MPEG-2, H.264 / AVC, H.265 / HEVC), and reduces latency through a hardware-accelerated decoding module.

[0025] Unification and post-processing of different signal formats has a resolution adaptive scaling function. The specific method is to uniformly convert input signals with different resolutions (such as standard-definition satellite signals, 4K IPTV) into the target output format through a bicubic interpolation algorithm; at the same time, it has dynamic HDR remapping, performs metadata-driven tone mapping on SDR signals, and matches the HDR capabilities of the display device.

[0026] The signal processing chip realizes seamless switching of signal sources mainly through real-time multi-dimensional perception and intelligent decision-making, including: Performing multi-dimensional signal quality evaluation through core index detection; Calculating the comprehensive scores of each signal source and discriminating the playback scene situation; Real-time monitoring of the signal situation. When signal degradation is detected, buffer the data of the backup signal source in advance and align the audio and video streams using the display timestamp.

[0027] The core metrics specifically include: physical layer parameters, network layer parameters, and content integrity; the physical layer parameters include: signal strength, signal-to-noise ratio, bit error rate; the network layer parameters include: network jitter (excellent when < 30ms), packet loss rate (< 0.1% threshold), end-to-end delay (< 100ms). Content integrity check: Detect continuity errors through PCR (Program Clock Reference) in the TS stream.

[0028] The formula for calculating the comprehensive score of each signal source is: Score = α×SNR + β×(1 / BER) + γ×(1 / Jitter) – δ×Latency; where α, β, γ, and δ are all adjustable weight coefficients, and by default, image quality is given priority; SNR represents the signal-to-noise ratio; BER represents the bit error rate; Jitter represents network jitter; Latency represents the end-to-end delay.

[0029] Identifying the playback scenario specifically includes: Live scenario: Prioritize low-latency signal sources (such as cable TV). VOD scenario: Prioritize high-bandwidth IPTV to ensure smooth 4K / HDR playback.

[0030] When signal degradation is detected, buffer the data of the backup signal source in advance (≥ 500ms buffer), and align the audio and video streams using PTS (Presentation Time Stamp); if the switch causes a short interruption, insert the last frame to maintain the image and smoothly transition through the frame interpolation algorithm.

[0031] It also includes periodic quality re-evaluation of the signal source: Re-detect the quality of the disconnected signal source and the backup signal source every period of time. When the quality of the disconnected signal source and the backup signal source is more than 5% better than the quality of the current signal source, switch to the disconnected signal source or the backup signal source.

[0032] The core processor module 4 uses a high-performance, low-power multi-core processor, which can quickly process various data including high-definition video streams and audio streams. This processor has a dedicated video decoding unit that supports multiple coding formats, such as MPEG-4, AVC (H.264), HEVC (H.265), AVS / AVS+, etc., to ensure smooth video playback.

[0033] The sensor module 5 specifically includes: a light sensor, a distance sensor, and a sound sensor; the light sensor is used to automatically adjust the screen brightness according to the ambient light intensity; the distance sensor is used to sense the operations triggered when the user approaches or moves away from the set-top box; the sound sensor is used to sense the voice commands of the user's operations on the set-top box.

[0034] The storage module 6 is equipped with a large-capacity cache and storage unit. The cache is used to temporarily store the video and audio data being processed, reducing playback stuttering. The storage unit can be used to download and store content such as the user's favorite programs and applications, facilitating offline viewing and use by the user.

[0035] The display output module 7 supports multiple display interfaces such as HDMI, DisplayPort, etc., and can output video signals with high definition, 4K or even 8K resolution to adapt to different types of display devices. At the same time, it can also automatically adjust the parameters of the output video according to the parameters of the display device to ensure the picture quality.

[0036] It also includes a terminal device 9 for presenting the processed signal data.

[0037] A control system of a multi-functional smart set-top box includes an intelligent operation subsystem, a content recommendation and personalization engine, an energy management subsystem, and a remote control and management subsystem.

[0038] The intelligent operation subsystem is used to support user operations and enables the user to run other applications while watching the signal data.

[0039] The content recommendation and personalization engine is used to analyze the user's viewing history, collection records, and search records and make targeted recommendations for the user.

[0040] The energy management subsystem collaborates with the sensor module 5 to dynamically adjust the power consumption of the set-top box: when the set-top box is in an idle state, it automatically enters a low-power mode to reduce energy consumption. When a user operation is detected, it quickly resumes the normal working state.

[0041] Fine-grained energy management is achieved through a hierarchical dynamic power consumption control architecture: Multi-modal sensor collaborative perception: a. User behavior perception: Pyroelectric infrared sensor (PIR): detects human movement within 3 meters (accuracy ±0.5m); HDMI-CEC linkage: monitors the on / off state of the external display device (e.g., automatically triggers standby when the TV is turned off); Voice wake-up module: triggers state conversion through keyword detection (e.g., "power on / pause").

[0042] b. Environmental status perception: Temperature sensor: continuously monitors the SoC temperature (accuracy ±1°C) and dynamically adjusts the heat dissipation strategy; Photosensitive sensor: adjusts the brightness of the LED indicator according to the ambient light intensity (0 - 1000Lux).

[0043] Intelligent state machine control: a. Six-level power consumption status: Status level Power range Functional characteristics Active(4K) 15-20W Full-function operation, HEVC hardware decoding Active(HD) 10-12W 1080p decoding, AI enhancement module turned off Standby 5-8W Maintain network connection, cache data Low-power 1-3W Only maintain DRAM refresh, wireless module turned off DeepSleep 0.5W Only RTC clock runs, timed wake-up detection Off <0.1W Physical power-off (requires hardware switch to wake up) b. Adaptive state migration: Idle detection algorithm: through operation interval histogram analysis (such as 30 minutes of no operation triggers downgrade); progressive power reduction: Active→Standby→Low-power→DeepSleep step-by-step switching (each level maintains a 30-second buffer).

[0044] The CPU frequency is adjusted in real time according to the load (1.2GHz→600MHz can reduce power consumption by 40%), the GPU rendering unit is powered in blocks (unused Shader cores are turned off), the power supply of unused interfaces is turned off independently (for example, only the HPD detection circuit is retained when the HDMI 2.1 interface is in standby mode), and the Wi-Fi / BT module is started and stopped as needed (wake-up detection firmware update every 30 minutes).

[0045] User behavior data and operation feature modeling: Establish a 24-hour usage heat map based on the user's button / remote control operation time distribution. Based on the voice interaction frequency and time period cluster analysis, obtain the user's live broadcast / on-demand duration ratio (live broadcast scenarios must maintain instant response) and 4K / HDR content playback ratio (affecting GPU power consumption allocation).

[0046] Preload the next 2 hours of programs based on user viewing habits (saving power consumption of real-time requests), and load on-demand content in 5-minute segments (avoiding continuous high bandwidth usage). Use LSTM neural network to predict user offline time (accuracy > 85%) and enter DeepSleep state in advance; use Always-On Cortex-M4 coprocessor to maintain minimal monitoring, and wake up the main CPU in advance when detecting remote control Bluetooth broadcast.

[0047] The remote control and management subsystem is used to remotely operate the set-top box, such as switching channels, adjusting volume, querying program information, etc. In addition, network administrators or parents can set the use rights of the set-top box through the remote management system, such as restricting access to specific content and setting usage time.

[0048] The present invention realizes the multi-function, multi-performance and high-quality user experience of the set-top box. When in use, the user connects the set-top box to the signal source through the corresponding signal receiving interface and connects to the display device through the display output interface. The user can operate through a remote control, voice command or mobile application, and the set-top box realizes the corresponding function according to the user command and the built-in algorithms, providing the user with a high-quality and intelligent multimedia experience.

[0049] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein, and should not be regarded as excluding other embodiments. Instead, it can be used in various other combinations, modifications, and environments, and can be changed within the scope of the concept described herein through the above teachings or the techniques or knowledge in related fields.
