ARINC 818 (Avionics Digital Video Bus) is a point-to-point, 8b/10b-encoded (or 64B/66B for higher speeds) serial protocol for transmission of video, audio, and data. The protocol is packetized but is video-centric and very flexible, supporting an array of complex video functions including the multiplexing of multiple video streams on a single link or the transmission of a single stream over a ...
Because 8b/10b encoding uses 10-bit symbols to encode 8-bit words, some of the possible 1024 (10 bit, 2 10) symbols can be excluded to grant a run-length limit of 5 consecutive equal bits and to ensure the difference between the count of zeros and ones to be no more than two. Some of the 256 possible 8-bit words can be encoded in two different ...

The 8 input bits of the 8B/10B code are conventionally identified by upper-case letters A through H, with A the low-order bit and H the high-order bit. Thus, in standard binary notation, the byte is HGFEDCBA. The output is 10 bits, abcdei fghj, where a is transmitted first. Coding is done in alternate 5-bit and 3-bit sub-blocks.
At 10 Gigabits per second, the expected event rate of a 66-bit block with a 65-bit run-length, assuming random data, is 66×2 64 ÷10 10 ÷2 seconds, or about once every 1900 years. The run length statistics may get worse if the data consists of specifically chosen patterns, instead of being random.
