I tried a quick google search on the Blu-ray header sizes when multiplexing certain streams but I couldn't get any information.
I am curious as to why this container format was chosen for the next generation of HD video when it's overheads are excessively large.
It seems that audio streams have the biggest influence and I have done some testing to see the differences. The most notable being a Dolby TrueHD stream that was increased 46% in size after being multiplexed into a M2TS stream... That's 46%!!
What is all that extra data for? Is there anybody with some information that would help me to understand what the overheads are comprised of and what they are used for?
How is it that every other container format can do the same thing with minimal overheads?
I am curious as to why the BDA chose this container format when it wastes space unnecessarily. It seems a shame to waste so much space when that could be used for extra bitrate or footage.
