    hello Jeff,

    thank you for your mail.

    i have already read to this document, but its all about hardware related.

    i want software requirements like codec layer migration from 365 to 368.

    also i came to know that DM368 doesn't have DVSDK, it has something called IPNV, but not sure

    but i am not getting all these informations from TI website. 

    kindly suggest me some document which will guide me the software requirements, codec engine etc for DM368.

    Hi Sujit,

    Let me just add a little more detail to Jeff's response. I am mentioning the details from IPNC Ref Design perspective.

    Ideally, DM365 to DM368 is completely software compatible. You should be able to run the same software that you were running on DM365.

    Ofcourse, the codecs (particularly H.264 encoder/decoder) have been improving to achieve performance of 1080P30 on DM368. This is possible in H.264 Enc/Dec ver 2.0 which will be available sometime in June 2010 for broad market release. While the codec was evolving, there have been some changes in the interface of the codec. The codec release will have documentation to explain and use the new interface. IPNC Ref Design already uses a pre-release of ver 2.0 codec and hence it has the interface changes for ver 2.0 codecs. If you have IPNC Ref Design, you can refer to IPNC ver1.9 release which is the latest available release and has the latest codecs to get the performance of 1080P30 on DM368.

    For IPNC Ref Design specific information, please refer to http://focus.ti.com/apps/docs/mrktgenpage.tsp?contentId=41246&appId=79

    BTW, going forward, all the platforms would be supported using DVSDK 3.10.xx. We already have DVSDK 3.1 for DM365. You can use it as your starting point for DM368 also.

    which i was using already with my dvsdk_2_10_01_18.

    and regarding IPNC i have IPNC1.5.

    As i had mentioned in my earlier post too, there is no DVSDK currently available for DM368. But as software is compatible between DM365 and DM368, you can try modifying the source code of DM365 DVSDK and use it for DM368.

    BTW, IPNC ver 1.9 supports DM368, so you might want to migrate to ver 1.9 if you want DM368 support and codec interface changes.

    Hi all,

    I also want to migrate from dm365 to dm368. My question is that after kernel porting will there be any changes in Applications?? The applications are about the Video encode, decode and audio encode decode. Please help me.
