Compressed Video Communications

Compressed Video Communications addresses the compression and transmission of coded video streams over mobile IP networks. By analysing a broad spectrum of compression techniques and error resilience algorithms this book provides realistic solutions to the problems of quality degradation and transmission error.Features include:* Discussion of the real-time transmission of coded video streams over mobile IP packet networks such as GPRS and UMTS, at both application and transport level.* Descriptions of relevant rate control schemes such as bit rate regulation, scaleability and resolution reduction.* Evaluation of the performance of compression techniques and comparison of available video coding standards.* Comprehensive overview of homogeneous and heterogeneous video transcoding algorithms and error resilient transcoders.* Examination of error control in video communications including coverage of error resilience and decoder-based error concealment.* Accompanying CD-ROM containing 50 video clips illustrating the temporal and spatial quality achieved by the compression techniques outlined in the text.Highlighting the quality of service issues associated with transmission over mobile networks, Compressed Video Communications is an essential guide for communications engineers and multimedia systems designers. This overview of the basic technologies and applications of digital video compression will also appeal to researchers and graduate students in the field.
