Recovery of Lost VQ Indexes in Packet Transmission
Abstract
We consider the problem of robust transmission of VQ-coded image/video via noisy packet networks. In the event of packet loss, some VQ index bits will be absent at the receiver side. But the very knowledge of lost packets identifies the spatial locations of affected VQ blocks, which are powerful information for the decoder to estimate the missing VQ index bits. This is possible because of the statistical redundancy between spatially adjacent VQ …
