Experiments with delivery of HDTV in IP networks
Conversion of broadcast television from legacy analog PAL and NTSC and standards in digital format, there are many exciting effects. They include the possible convergence of television and computer network infrastructures, allows interactive applications, as well as enhancement of the quality of possible with high definition digital formats.
To this date, the various aspects of this approximation are examined separately: there has been much work on the transport of compressed standard definition Television during the IP, and a lot of work, established protocols and standards for high definition television (HDTV), but few have studied the transport of HDTV in the IP. In this paper we present our initial experiments with the system to deliver production quality decompresses HDTV by IP networks.
Why choose to deliver uncompressed HDTV? Several reasons, primarily to maintain the quality of the image and reduce latency. This is most useful in the production facility, where the undesirable image deterioration because of repeated compression cycles, but might be appropriate for telepresence applications, very high quality. Supply of compressed HDTV, using existing MPEG-2 IP standards may be more appropriate for other applications.
The structure of this document is as follows: section 2 covers background in HDTV technologies, protocols for transport of video in IP networks and network performance. This was followed, in section 3 to discuss the possibilities for the development of a protocol with our project, described in section 4. Section 5 provides for the prior performance analysis of our system, showing the transmission of HDTV in wide-area IP network, with section 6 outlining guidelines for further development. Finally, we summarize work in section 7 and provides conclusions.
