Error concealment at the video decoder is to recover erroneous picture region based on correctly decoded region in the same frame or the neighboring frames. However, error concealment cannot give satisfactory result in some cases, e.g. when a whole frame is lost. In this paper, we propose a novel backward error concealment method. While the existing temporal error concealment methods recover an erroneous...
Reverse playback is one of the most common video cassette recording (VCR) functions for video streaming systems. However, the predictive processing techniques employed in traditional hybrid video coding schemes severely complicate the reverse-play operation. In this paper, we enhance our previously proposed bidirectionally decodable Wyner-Ziv video coding scheme which supports both forward decoding...
Inter frame prediction technique significantly improves the compression efficiency in the hybrid video coding schemes. However, this technique causes the decoding dependency of each inter frame on all of its reference frames. This dependency complicates the reverse play operation which is the most common video cassette recording (VCR) functions. This dependency also causes error propagation when the...
