SYSTEM OF DATA TRANSMISSION, TRANSMISSION DEVICE, RECEIVING DEVICE, METHOD OF DATA TRANSMISSION AND PROGRAM

摘要

FIELD: information technologies. ^ SUBSTANCE: source of high definition multimedia interface determines if data acceptor of high definition multimedia interface can receive backup signal for advanced enlarged data of display identification. When data acceptor of high definition multimedia interface can receive backup signal, source of high definition multimedia interface adds backup signal to data of main image pixel consisting of pixel data, their number of bits is lower than that of transmission pixel data transmitted by transmitter thus composing transmission pixel. These data are transmitted by means of transmitter via channels No. 0 - No. 2 of transient minimised differential transmission of signals (TMDS). Besides source of high definition multimedia interface transmits package of general control containing information of backup signal which indicates if backup signal is available in data of transmission pixel in control period during period of vertical beam return. ^ EFFECT: effective transmission of data using high definition multimedia interface which allows transmission of uncompressed image pixel data with high speed in one direction. ^ 21 cl, 57 dwg
