Reed-Solomon Encoder

Reed-Solomon codes are used to perform Forward Error Correction (FEC).

Overview

Reed-Solomon codes are used to perform Forward Error Correction (FEC). FEC introduces redundancy in the data before it is transmitted. The redundant data (check symbols) are transmitted with the original data to the receiver. For example, a Reed-Solomon decoder is used to help recover any erred data. This type of error correction is widely used in data communications applications such as Digital Video Broadcast (DVB) and Optical Carriers (i.e. OC-192).

The codes are referred to in the format RS(n,k) where k is the number of s-bit wide information (data) symbols and n is the total number of s-bit wide symbols in a codeword. The Reed-Solomon encoder generates a code such that the first k symbols output from the encoder are the information symbols and the next n-k symbols from the encoder are the check symbols added for error correction. When the data output is in the same order as the input it is referred to as a systematic encoder.

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.
