In-Depth Information
The statistical properties of the SHV source signals are not effectively utilized
in the current HDTV encoders. A future goal is to share the SHV source informa-
tion between the encoders to improve compression performance further.
4 Demonstrations and Experiments
4.1 IP Transmission
On March 14, 2006, NHK carried out an experimental transmission of SHV using
the MPEG-2 coding system at bit-rates of 300 and 640 Mbps via gigabit IP net-
works over a distance of 17.6 km. The IP transmission system was also success-
fully demonstrated at NAB 2006 in the US from April 24 to 27 [1] and IBC 2006
in the Netherlands from September 8 to 12 [2].
