[Mp4-tech] H.246 on DVB

[Stephen Henry]

Hi all,
I have a couple of questions, could someone please help me with them?
I'm interested in using H.264 for HDTV and higher resolutions. To me, it
seems like the natural way to enhance a hardware accelerator for H.264
is through parallelizing the system using multiple slices. For example,
four independent encoders can encode 4 quarters of the one frame in a
quarter of the time of just one. What I wanted to know is whether it
would be safe to assume whether this can be done at the decoder as well?
I was thinking that it is unlikely that for broadcast H.264, high
resolution frame would need to be partitioned into slices to be encoded
in real time and therefore it would be safe to assume that such
parallelism is available at the decoder as well.
Does anyone know whether the DVB standards impose a number upon the
minimum number of slices that a decoder can assume are present?
Thanks,
SCH
