16:9 interlaced hD1 proxed by Apache 750 Kbps (overall 873 Kbps) wrapped in an mpeg4 media base format (MBFF, ISO 14496-16) and stream as a MPEG2 (DVB) TS
In order to test the streaming capability, I've used a small portion (about 600 seconds) of the movie Home
realised by Yann Arthus Bertrand in 2009, copyright Europa Corp, publicly viewable on many web sites.
I've added a specific page with all the disclaimer and additional informations.
The video here embedded is heavy compressed and has two further level of information reduction: the interlacing
(half image -- odd or even lines -- every 1/50 of second instead of 25 progressive images per second)
and the usage of half horizontal resolution decreasing the number of macroblocks. In the mid 90ies, when the computational
power of real time encoders was not sufficient for an acceptable quality at very low bitrate.
At that time progressive scanning was out of scope in television and a PAL video required mean 6-8 Mbps.
We used to call this reduced horizontal resolution PAL encodings half-D1.
Reducing the horizontal resolution divided by two the number of macroblocks.
Today the limit is not in the computational power (the digital correspondant of limited bandwidth circuits capability),
but the stream bandwidth toward the channel bandwidth. In term of bandwidth an interlaced 50 frame per second video carries
the same bandwidth of a 25 progressive frame per second, the half. So with interlaced video we have a lower probability to suffer bandwidth bottleneck.
