Video Encoding, and the need for SATA

Other Parts Discussed in Thread: OMAP-L138

Hey Everyone,

 

So I'm exploring the possibilities of doing on demand video encoding. The use case is somethign like, this. You have high-def vide files on a harddrive, and you wish to encode them to a more streaming friendly format and transmit. I was exploring the DaVinci and the integra solutions and have a question to help with selecting the processor. I'm looking at combine DSP + GPP solution. The Davinci series has video cprocesor units that will handle H.264 encoding which is very appealing. However it doesn't seem to have a SATA interfce whic means I won't be able to read of a hard disk (or at least I dont' think so). The integra solutions have SATA ports but lack the video co=processors. I was wondering, is it possible to use the DSP in the integra solutions to implement accelerated encoding. Would this provide any acceleration when compared to a purely software based encoding. Also, does the TI codec engine help construct the said codec on top of the DSP? Finally, are such codec available freely or are they IP which require purchasing. ANy help with this would be much appreciated.

 

Thanks

Kartik

    Hi Kartik,

    Do you have to use SATA? DM646x family has PATA connection. We will have some commenting on the integra side soon.

    Kartik,

    The Integra family includes two processors with SATA connectors. The OMAP-L138 has a SATA connection, and up to a 456hz  DSP available to do video encoding/decoding.  The C6A8168 has a SATA connection and up to a 1.5GHz DSP available to do video encoding/decoding. 

    The TI codecs are freely downloadable and available for use. Note that the Integra family does NOT include video acceleration. For video acceleration, we recommend the DaVinci family that includes DSP+ARM+Video Accelerators. Although the DSP in the Integra family can do video, we recommend customers that want processors tuned for video performance to use the DaVinci family.

    Future DaVinci roadmap parts will likely satisfy your needs. We suggest you reach out to a TI salesperson who can provide you with more information. Alternatively, you can email me at huy@ti.com and I can put you in touch.

    Best Regards,
