Abstract: A timing controller includes: an image input module configured to output respective raw data according to accessed video source data; a data processing module configured to buffer the raw data in one row and splice each row of raw data into display time control data and display luminous control data; a grayscale mapping and dividing module configured to establish a mapping relationship between the display luminous control data and a high grayscale and a mapping relationship between the display time control data and a low grayscale, to output display data; and a timing control module configured to control writing of the display data.

Abstract: A multimedia data transmission apparatus and method are provided. In the method, a data receiver receives at least one channel of multimedia data and transmits the received multimedia data to a selector and a data synthesis module. The selector selects target multimedia data from the received multimedia data and transmits the target multimedia data to a data processing module. The data processing module performs a format conversion on the target multimedia data to obtain converted data and transmits the converted data to a data transmitting module. The data synthesis module synthesizes the received multimedia data to obtain synthesized data and transmits the synthesized data to the data transmitting module. The data transmitting module transmits the converted data to a first processing device and transmits the synthesized data to a second processing device.
