BLOCK CODING FOR DIGITAL VIDEO TRANSMISSION

摘要

The transmission of digital video data is accomplished using a block coding scheme, which embeds timing and control signals into the data stream. The code is DC balanced, achieved by selectively inverting some data blocks, as a function of the cumulative disparity; and the transitions within each block are controlled, providing either a minimum number of transitions per block, or a maximum, and this is achieved by selectively inverting certain bits within a block. The use of low-swing differential transmission minimizes electromagnetic interference (EMI).
