DM368 h263 enc+dec perfomance

Chris Meng

Hi,

Would you pls kindly advise what's the performance for DM368 to run h263 enc and dec at same time? Can you give performance for universal h263 decoder and closed loop h263 decoder separately?

I found the MPEG4 encode on HDVICP can support h263, but there is not performance data for h263. Pls kindly help.

Chris,

The performance on H.263 is almost same as that of Mpeg4 codec. This is true for both VICP and HDVICP codecs. Please note that both VICP and HDVICP codecs supports H.263. Short header mode is same as H.263.

Yashwant,

I can't find h263 support in the datasheet of MPEG4 enc (v1.10.00.03) and dec (1.10.00.01), You may update the datasheet.

One more question:

We found below at http://processors.wiki.ti.com/index.php/DM365_Codec_Availability_Schedule. Is the decode below univerisal or close-loop decoder?

Video Encode & Decode (multi-channel)
MPEG4 SP Encode + Decode 30fps (simultaneous)	4xCIF/ 4xCIF - at 30fps	300HMz	Available
H.264 HP Encode + Decode 30fps (simultaneous)	4xCIF Enc + 4xCIF Dec - at 30fps	300HMz	Available	Actual performance may vary depending on the system load

Chris,

The mpeg4 number is with closed loop VICP based decoder. For H.264, it is universal decoder. In summary -
