The first terminal obtains a fourth message sent by the local processing center, where the fourth message carries second update information obtained after the local processing center performs a preset processing operation on first update information, and the first update information is information obtained by the remote processing center in response to the first message or the third message. The first terminal updates output information of the first terminal based on the second update information carried in the fourth message.

A digital television and a signal processing apparatus thereof are disclosed. The digital television signal processing apparatus includes a control PCBA board and a digital demodulator standard module, wherein the digital demodulator standard module is detachably connected to the control PCBA board, the digital demodulator standard module is configured to demodulate a digital television intermediate frequency signal to obtain a digital transport stream signal, and the control PCBA board is at least configured to decode the digital transport stream signal. According to embodiments of the present disclosure, the digital demodulator standard module only needs to be replaced to accommodate different countries and regions, while maintaining the PCBA control board unchanged; in this way, the entire PCBA board doe not need to be changed, thereby reducing complexity in maintenance of a plurality of PCBA control boards, and promoting material universalization.

This disclosure describes devices, systems and techniques relating to a dongle device that is designed to provide broadcast video capabilities to an electronic device. In one example, a dongle device is configured to communicatively couple to an electronic device, wherein the dongle device comprises a multimedia receiver that receives a broadcast that includes multimedia data, and a web server that communicates the multimedia data to a web browser of the electronic device.

The invention relates to a system, a method of a remote control adapted to display media content from the World Wide Web. This is accomplished by utilizing a smart-phone as a remote control by an application program, and transmitting the media content through a backend system utilizing WI-FI adapters to transmit streaming media to for instance a HDMI TV. Moreover, the invention provides viewing already aired programs through an electronic program guide (EPG).

In a video signal transmission system using fiber optic cable, an improved optical transceiver module (fiber module) having integrated video signal processing capabilities can be used in video signal transmitters for video sources, video signal receivers for display devices, or video switching devices. The improved fiber module has a form factor complying with the Small Form-factor Pluggable standard, and a standard optical fiber connector. In addition to an optical transceiver, the improved fiber modules includes a ¼ inch signal processing chip programmed to perform video signal processing. The mainboard of the video signal transmitter or receiver or the video switching device has additional signal processing chips for processing non-video signals such as audio, data, network, RS-232, and IR remote control signals, but they do not perform video signal processing. Another embodiment is a fiber optic cable with an electrical signal connector module that integrates a video signal processing chip.

A video signal transmitter or receiver for handling multiple video signals, including mainboard signal processing circuitry, one master fiber module, and one or more add-on fiber modules. Video data signal for the multiple videos are transmitted over the master and add-on fiber modules, but no video control signal is transmitted over any add-on fiber module. Video control signal for all of the multiple videos are transmitted on a first subset of channels of the master fiber module in a multiplexed manner. The mainboard signal processing circuitry cooperates with the signal processing chip of the master fiber module to process all video control signals, with the master fiber module processing video control signals for at least two videos. Non-video signals are processed by the mainboard circuitry and transmitted on a second subset of channels of the master fiber module (same as or different from the first subset of channels).

Video processing devices, systems and methods are disclosed. A control device, a capture device, and at least one cooperation application are provided. The cooperation application configures the capture device and control device to communicatively pair for cooperation with one another to perform a video processing operation. The cooperation application determines a split of video processing tasks between the capture device and the control device. A first set of video processing tasks are performed by the capture device, and a second set of video processing task are performed by the control device.

The present application discloses a video processing method, an electronic device, and a computer-readable medium. The method comprises: a system playing module acquiring a video file to be played and sent by a target client; determining whether playing of the video file is supported; if not, parsing the video file to acquire an audio stream and a video stream in the video file; configuring an audio decoder identifier for the audio stream, and configuring a video decoder identifier for the video stream; and sending to an FFmpeg module the video stream, the audio stream, the video decoder identifier, and the audio decoder identifier, such that the FFmpeg module decodes the video file to acquire audio playing data and video playing data, wherein the audio playing data and the video playing data can be played by an audio and video output module of an electronic device.

Introduced here are systems to manage and discover a processing offloader. A first multimedia device may identify a processing offloader in a networked environment. A first multimedia device may determine that a bandwidth of a second multimedia device in the networked environment falls below a threshold bandwidth, indicating that the second multimedia device may process instructions and render multimedia information with increased latency or delay. Based on this determination, the first multimedia device may forward instructions from the second multimedia device to the processing offloader for the processing offloader to process and render multimedia information on behalf of the second multimedia device based on the received instructions. The first multimedia device may forward rendered multimedia information from the processing offloader to the second multimedia device, and the second multimedia device may output the rendered multimedia information to an output device.
