HDMI cable transmission

Data transmission HDMI will signal coding into three serial bit stream, and through the three difference in transmission.

These serial bit stream of data transfer rate is transmitter and receiver clock transmitted between 10 times. Serial bit stream used called TMDS coding technology, its function is to reduce the number of jump, and at the same time prevent had long 0 or 1 string appear in DC wandering or signal heavy synchronization problem.

 Audio signal is in the video line blanking when transmission, and with reference to audio clock can recover at the receiving end. The video horizontal blanking period size has the strict request, it must ensure enough bandwidth to transmit audio signal.
