BBC MPEG-4 AVC HDTV DVB-S2 teststream from the IBC

[bond]

stumbled over this file (http://stud4.tuwien.ac.at/~e0326863/ats/bbc-sample_small.mpg) which seems to be from the BBC's test avc broadcast stream shown on the IBC judging from this (http://e-pressroom.com/cgi-bin/ibc_ep_release04.cgi?db_id=4258&doctype=txt) and this (http://www.bbc.co.uk/rd/milestones/2000s.shtml).
if its indeed from the IBC than its encoded with tandberg's avc encoder, also used by sky and premiere, the two channels also already showing hdtv avc broadcasts

Well spotted Bond.

I meant to write something about this last week, after reading an article in one of my magazines....

I'll have to try and find it again and report back ;)

It is possible that this file is encrypted besides encoding in Tandberg Mpeg-4.
please give more details about broadcast data.

I'm able to play the BBC sample using Nero's filters, which report the video to be MPEG-4 AVC.... but it would be useful to de-mux the stream to its raw format!

mplayer -dumpvideo -dumpfile raw.264 bbc-sample_small.mpeg

possible with mplayer too:
mplayer -dumpvideo -dumpfile raw.264 bbc-sample_small.mpegI don't have mplayer installed...

Could you oblige, zip and e-mail (SeeMoreDigital@msn.com) the stream to me please ?

Does this clip have an audio element... Nero's filters can't detect anything?

its 10mb i dont think my mail can handle this, also 7zipping actually makes it slightly bigger :D

for extracting it yourself you simply need to place mplayer into a folder (not need to install anything), create a new .txt file in the same folder, copy the line i posted above into the .txt, save it, rename the .txt to .bat and execute the .bat
thats all :)

there is no audio in the file it seems
