Abstract
Official abstract text for this publication.
In a communication system, parallel encoding and decoding of serially-coded data occurs in a manner that supports low latency communication. A plurality of data items may be coded as serially-coded data sequences and a transmission sequence may be built from them. An index table may be built having a plurality of entries representing respective start points of the serially-coded data sequences within the transmission sequence. The transmission sequence may be transmitted to a channel and, thereafter, the index table may be transmitted. Latencies otherwise involved in inserting an index table into the beginning of a transmission sequence may be avoided.
First claim
Opening claim text (preview).
We claim: 1. A method, comprising: coding a plurality of data items as serially-coded data sequences, the coded data sequences having lower bit rates than the data items, building a transmission sequence from the serially-coded data sequences, building an index table having a plurality of entries representing respective start points of the serially-coded data sequences within the transmission sequence, and transmitting the transmission sequence and the index table in a chann…
