Method and Apparatus for Transporting an 8B/10B Coded Video Stream Across a 64B/66B Coded Link

摘要

A video transport system is provided for transporting as 8B/10B coded video stream across a 64B/66B coded link, wherein forward error correction is provided without the overhead of the prior art. The system also provides a system with the ability to recover 64B/66B Encoded blocks that have corrupt Sync bits.

1. A method for transporting an 8B/10B coded video stream from a transmitter across a 64B/66B coded link to a receiver wherein data block types are predefined, the method comprising:
placing 4B/8B information bytes in control blocks by said transmitter to identify the control block, map the location of data bytes and control bytes, select the next data block type and encode redundant information used to identify control blocks when the sync bits are corrupt; and packing redundant information by said transmitter in 64B/66B control blocks whereby said receiver may reliably distinguish between 64B/66B control and data blocks when the 64B/66B sync bits are corrupted by checking the block format and said redundant information, and if said block format and redundant information are consistent with a valid control block, the receiver interprets the 64B/66B block with corrupt sync bits as a control block, and otherwise interprets the 64B/66B block as a data block.
