Is it possible to correlate the objective measurements of analog and digital performance specification?
The VTC/VT Subworking Group’s goal is to answer these questions. It has become a first step to the process of constructing the performance standard. Trellis Coding Trellis coding is a source coding technique that has resulted in numerous publications and some very effective source codes. Unfortunately, the computational burden of these codes is tremendous and grows exponentially with the encoding rate. A trellis is a transition diagram, that takes time into account, for a finite state machine. Populating a trellis means specifying output symbols for each branch, specifying an initial state yields a set of allowable output sequences.
