Practical Considerations of LDPC Decoder Design in Communications Systems

This paper covers some practical aspects of designing the LDPC decoder starting from comparison between different techniques, different decoders parameters or standards, the effect of those parameters on the LDPC performance, also it discusses the algorithm selection process, and floating point implementation process.

Audio Transport in DisplayPort VIP

DisplayPort uses Secondary Data Packets (SDPs), which are transported over the Main-Link that are not main video stream data. This allows it to carry audio and video simultaneously. The VIP supports audio transmission both in the original mode as defined in the specification as well as just as any other SDP being transmitted.
