Compressed Video Communications

Digital video communications, supported by the Internet, ATM networks and Broadband ISDN, have undergone significant development over the past few years. Emerging applications include videoconferencing, tele-medicine and distance learning. This leading edge text addresses the problems associated with the delivery and design of video communication services.

• Presents a comprehensive overview of the principles and techniques employed in the improvement of the performance of video codecs in error prone environments
• Provides a performance evaluation and comparison of video coding standards, MPEG-4, H.261 and H.263
• Outlines methods of video communication over mobile networks
• Provides guidance on quality enhancement and the meeting Quality of Service (QoS) requirements for digital video communications
• Accompanying CD-ROM containing video clips to illustrate the coding and error resilience technology described within the text
