German channel bw (Bundeswehr TV), designed for branch offices and bases of the German army, is gearing up for changes in the way of distribution. March 23 began emissions tests in MPEG-4. Issue is conducted with the same parameters as before and is responsible for its continued Media Broadcast. New encryption - on the occasion of the transition to MPEG-4 broadcaster resigns broken PowerVu system.
The transition to MPEG-4 allows you to reduce the bit rate required to ensure the quality level so far and I can see it from ongoing at 13 ° E test media. bwtv need around 3.8 Mbit / sec video transmission in MPEG-2 and MPEG-4 uses only approx. 2.53 Mbit / s.
On the occasion of the new message is no longer encrypted in PowerVu system, and Conax. The step is logical, because PowerVu long been the victim of hackers and is no longer safe, even though the sender bwtv weapons by frequent changes of keys (even several times a day).
It is not known how long it will take parallel issue, but you suspect that reception equipment is not much in circulation, to provide novel receivers should take no longer than a month (and not excluded that the exchange has already started).* In addition to the channel is also broadcast station Radio Andernach.
