Hi All ,
I want to record hdmi output from setup box to my laptop . I need advise on which TI chip will be cheapest to implement this . The TI chip should have hdmi input and output as MPEG4 (h.264) . I want to send the Mpeg output to pc using USB . If you can point me to any sample design , will be very helpful to me .
Thanks
Rohit
There is not an easy way to do this from a legal perspective.
All set top boxes, DVD, Blu-ray players etc... will copy protect the HDMI output with HDCP.
In order to be able to design a system which includes a HDMI receiver which is able to decode the copy protection you MUST sign a license agreement with the HDCP licencing body.
You can find more information here...

Basically, you need to ensure you are a licensee and have a $5M+ indemnity policy in place before you are allowed to have access to HDMI receivers able to decode the HDCP copy protection.
TI does not produce HDMI receivers so you will need to source these from other companies like Silicon Image, Analog Devices etc...
These HDMI receivers can then easily be connected to many different TI video processors.

But Can I record Audio Video using component video output of setup box ? . Please advise which TI chip will be good to record component video from setup box to pc .

For analog RGB or YPbPr you can use the TVP7002, yes.
Be aware though that many more recent set top boxes and Blu-ray players etc... will decimate the component video resolution so whilst it 'appears' to be 1280x720p for example it is actually decimated down and scaled back up, so you do not really get what you paid for, so to speak. thank the movie industry for this 'feature' !!
There is a daughter card which has a TVP7002 available. Please contact your local TI representative for more information on where/how to purchase this daughter card.
Thanks Steve but I need to capture it in my computer , so I need to send the digital rgb output of TVP7002 through usb to my computer . Can I send the raw digital RGB directly to USB or I need another chip to convert RGB to standard format of MPEG 4 and then send the data through usb to my pc . I mean do I need another chip like TMS320DM365 to send the data to USB . The USB speed is around 480 Mbps . So is there any way I can avoid encoding chip like TMS320DM365 and can directly write digital RGB output without any encoding to USB port of PC .
Sorry, I miss-understood.
I thought you had already device on a particular video processor and was simply asking about getting the video into the processor.
Yes, you will need a video processor to compress the video to MPEG, H.264 or some other format since the bandwidth required for video is significantly higher than 480MBit of USB.
RGB is a little more difficult to work with than YUV since most if not all video codecs process video in YUV420 format which decimates the color.
