Sequential Decoding of Mpeg-4 Coded Bitstreams for Error Resilience
نویسنده
چکیده
In this paper we present the results of a method for decoding start codes and overhead information in an MPEG-4 bitstream using sequential decoding with soft channel values. We show that performance of sequential decoding is superior to that of hard decisions alone and can be further improved if probabilities of occurrence of the start codes are taken into consideration.

. Soft source decoding with applications
Motivated by recent results in joint source-channel coding and decoding, we consider the problem of decoding of variable-length codes using soft channel values. We present results of decoding of selected codes using the maximum a posteriori (MAP) decoder and the sequential decoder, and show the performance gains over decoding using hard decisions alone. The objective behind this work is to prov...
متن کاملField-To-Frame Transcoding with Spatial and Temporal Downsampling
We present an algorithm for transcoding high-rate compressed bitstreams containing eld-coded interlaced video to lower-rate compressed bitstreams containing frame-coded progressive video. We focus on MPEG-2 to H.263 transcoding, however these results can be extended to other lowerrate video compression standards including MPEG-4 simple pro le and MPEG-1. A conventional approach to the transcodi...
متن کاملTrellis Decoding for MPEG-4 Streams Over Wireless Channels∗
Most video coding standards, including MPEG-4, use variable length codes to encode the discrete cosine transform (DCT) coefficients of intra frames and inter frames, and the motion vector information. Although variable length codes can achieve good compression, they are very sensitive to channel errors, especially in wireless channels, which are characterized by bursty errors. Joint source-chan...
