Abstract

Motivated by error-robust mobile multiplexer what was called H.223/Annex A, we investigate restriction of H.263 functionality in H.324 mobile terminals against error-prone channel. Although H.223/A employs strong error protection schemes such as rate compatible punctured convolutional code and automatic retransmission on request, it cannot detect errors is encoded video bit stream. In order to further increase the performance of the total H.324/M system, it is desirable to reduce functionality of H.263 so that H.263 decoder can easily locate errors in incoming H.263 stream, which cannot be made possible by H.223/A. We suggest one possible way to achieve H.263-compatible and reduced functionality incorporated with a new mobile multiplexer in wireless links aiming at enhancement of visual quality at receiver.
