Compressed high definition television (HDTV) over IPv6

Abstract

In this paper, we introduce the compressed HDTV over IPv6 system, applications, and its experiment in IPv6 network between Korea and China. We developed the compressed HDTV over IPv6 system which requires 20-25Mbps with MPEG2. The system use 720/30p or 1080i HDTV format and support IPv4/IPv6 and unicast/multicast. The compressed HDTV system provides high quality audio and video with relatively small bandwidth comparing with uncompressed HDTV system, but it suffers about 1 second delay for MPEG2 encoding and decoding. Its high quality video and audio enables applications such as remote lecture/seminar with limited interaction. Using compressed HDTV system, we had two-way experiment which requires 40-50Mbps bandwidth in Gigabit IPv6 network in dual stack mode. This paper contains brief experiment result including jitter and packet loss. We expect practical application of compressed HDTV system such as remote lecture and seminar between Korea and China
