Abstract: A signal processing device is disclosed, which includes a plurality of channel receivers, a plurality of time code processors in one-to-one correspondence with the channel receivers, a timing generator, a signal processor and a transmitter, wherein each channel receiver is configured to parse an audio-video signal which has a data format defined by the SDI protocol and including a time code that characterizes time information. Each time code processor is configured to extract the time code from a parsed audio-video signal obtained by a corresponding channel receiver, and form first frame image data including a frame time code. The signal processor is configured to form an absolute frame output image based on multiple channels of the first frame of image data, frame time codes therein, and an internal clock signal generated by the timing generator. The transmitter is configured to transmit the absolute frame output image for display.

Abstract: A display driving device, a control method therefor, and a display apparatus. The control method comprises: a main processing chip generates a read-write synchronization signal when buffering received display data, and each secondary processing chip receives the read-write synchronization signal (S202); in response to the read-write synchronization signal, the main processing chip buffers the received display data of the current frame image to be displayed to the frame address of a corresponding memory, and performs reading and processing on the buffered display data of a previous frame image to be displayed and then transmits to a display panel, and in response to the read-write synchronization signal, each secondary processing chip synchronously buffers the received display data of the current frame image to be displayed to the frame address of the corresponding memory, and synchronously performs reading and processing on the buffered display data of the previous frame image to be displayed and then transmits to the display panel (S203). By means of the read-write synchronization signal, the main processing chip and all the secondary processing chips are controlled to control the storage and read operations of the memory, and thus, the present invention can avoid that the processing chips share the frame address of the memory, and further can avoid the problem of abnormal image display due to multiple asynchronous processing chips.
