C6678 H264HP Scale Question

YC, Tsai
Intellectual 590 points

Hi

My customer plans to use C6678 to integrate the following:

1. scale h264 hp 1080P60 to H264 HP 720p25

2. scale h264 hp 1080P30 to H264 HP 720p25

 

My customer would like to know how many cores will method 1 and 2 be used? Thank you.

I also post the thread on Keystone multicore Forum

Regards,

YC

    Hi YC, 

    From the encoder side we have H264 HP 720p30 needs 4 cores. Depending on used tools (for example CAVL instead of CABAC or less B frames, etc) it might be possible to squeeze 720p25 in 3 cores. Please check H.264 Encoder data sheet for more details

    http://software-dl.ti.com/dsps/dsps_public_sw/codecs/C6678/H264HP_E/latest/index_FDS.html

    From the decoder side we have that we can use 4-core decoder for decoding in real time a 1080p30 stream. 1080p60 could be decode but it won't be in real time. For more information please check H.264 Decoder data sheet

    http://software-dl.ti.com/dsps/dsps_public_sw/codecs/C6678/H264HP_D/latest/index_FDS.html

    About scaling our TSU (Image Resizing) can be fit in less than 1 core.

    thank you,

    Hi Paula,

    Thank you very much for the prompt reply. Now I can estimate H264HP codec integrity for my customer.
