HD 1080i capture using DM648 EVM

Hi

 

I was reading the DSP/BIOS VPORT Device Driver Release 1.10.00 doc that came with the EVM and it says the following:

2. HD capture (720p and 1080i) is not supported in this release.
Currently facing some EVM problems and hence HD capture was not
tested thoroughly in the EVM with proper fix.
This driver doesn’t support HD capture (720P and 1080I). These functionalities are
not yet tested properly.

Yet I have read several forum discussions where it seems people are able to do 1080i.

The dvsdk version I have is dvsdk_1_10_00_26_DM648. Board is LYR179-101C, 690-275-C. TI chip is TMX320DM648AZUT $N11 81ALHCW.

Can this board/release do 1080i HD capture and display?

Cheers

    Response from Lyrtech

    ++++++++++++++++++++

    Your board revision is C2.

    This board and all production boards support HD capture/output correctly at
    1080i/720p.

    Part 1:

    To verify, you can just run the binaries (without recompiling) of the
    Lyrtech projects provided with the evm (if you installed Lyrtech evm bsl cd
    in default directory) (you must install evm rev c2 Lyrtech BSL software
    CD):

    (Connect a component video analog monitor on J14 using the provided cable.
    This test by default will output 1080i colorbar (720p after minor modif))
    C:\Lyrtech\EVMDM648\BSL\Example\HDVideoColorBar_tst\Debug\HDVideoColorBar_ts
    t.out

    (This test will just do a HD video loopback. To run this test, you need
    analog hd component video 1080i source like dvd player connected to J10.
    You will need a 2nd component video adapter cable not provided with the evm.
    The capture image will be output similar like previous test (minor modif and
    recompile is needed for 720p))
    C:\Lyrtech\EVMDM648\BSL\Example\HDVideoDigLoopBack_tst\Debug\HDVideoDigLoopB
    ack_tst.out

    Part 2:

    If you want to build real video application using TI provided DVSDK, you
    need a recent version. The latest version of dvsdk is available free once
    the evm is registered on TI web site.

    The latest TI DVSDK version is v1_11_00_00 (Jan 2009) you can download from
    TI web site extranet.

    Sincerely,

    Technical Support Team
