The growth of the Internet has fueled the demand for enhanced watermarking and data
hiding technologies and has stimulated research into new ways to implement watermarking …

Video information lost as a result of transmission errors. The system and method have four
aspects, including:(1) chang ing the bit and/or packet rate;(2) inserting redundant infor …

The problem of controlling access to multimedia multicasts requires the distribution and
maintenance of keying information. Typically, the problem of key management is considered …

ENPROCESS metadata capacity. The prediction mode can be encoded according to a
mode table that relates mode to bits and by considering coding impact. Start and stop codes …

In this paper, error-resilient video coding schemes based on data-embedding techniques
are proposed for the H. 263+ codec. Data embedding, popularly applied to secret hiding and …

In recent years, joint source-channel coding for multimedia communications has gained
increased popularity. However, very limited work has been conducted to address the …

H. 264/AVC is a novel video coding standard that provides better coding efficiency than
previous video coding standards. In this paper, we propose a new error resilience scheme …

For entropy-coded H. 264/AVC video frames, a transmission error in a codeword will not
only affect the underlying codeword but also may affect subsequent codewords, resulting in …

The implementation of present day video compression standards, such as MPEG, H. 263
and JVT (also known as ISO/ITU H. 264) result in the division of video frames into …

In this paper, a prescription-based error concealment (PEC) method is proposed. PEC relies
on pre-analyses of the concealment error image (CEI) for I-frames and the optimal error …
