Abstract: The present disclosure provides a video and audio signal processing chip, a video and audio signal processing device including the same, and a video and audio signal processing method. The video and audio signal processing chip includes a signal detection module, a storing unit and a controller. The signal detection module is configured to detect and store video and audio signals. The controller is configured to: transfer the video and audio signals from the signal detection module to the storing unit; and transmit the video and audio signals stored in the storing unit to a host.

Abstract: A display control integrated circuit (IC) applicable to performing multi-display processing in a display device includes multiple sub-circuits such as a Multi-Stream Transport (MST) stream splitting module, multiple video format conversion circuits, a multiplexer and a video combination module for generating a combined picture for being displayed. The display control IC may utilize at least one additional data path coupled to at least one predetermined sub-circuit among the multiple sub-circuits to obtain at least one signal, and output any signal of the at least one signal through a video output terminal of the display control IC and a video output port of the display device to be a video output signal for further use, where the at least one predetermined sub-circuit include at least one of the MST stream splitting module and the multiplexer.

Abstract: A system capable of upgrading a firmware in the background and a method for upgrading a firmware in the background are provided. The method for upgrading the firmware in the background partitions the memory module of an electronic device, one user code sector is used to normally execute an initial firmware and an upgrade flow, and the other user code sector is used to store an upgrade firmware.

Abstract: A video transmission method and a system thereof are provided. The video transmission method includes: obtaining a first display timing setting parameter of one or more display devices. A total transmission bandwidth of the display device is calculated according to the first display timing setting parameter, and when the total transmission bandwidth is greater than a maximum transmission bandwidth between a video source and a conversion device, a second display timing setting parameter with a lower bandwidth is generated corresponding to the first display timing setting parameter. The video source transmits a video signal conforming to the second display timing setting parameter to the conversion device. The conversion device converts the second display timing setting parameter of the video signal back to the first display timing setting parameter. The video signal conforming to the first display timing setting parameter is transmitted to the corresponding display device.
