blueroomelectronics said:Which manufacture's DSP are you interested in?
blueroomelectronics said:A DSP micro is an advanced part, and the project you described is very complex. Much more difficult than testing a stepper motor.
There are many DSP development systems, not sure what you can get in India though.
Plus nobody will be able to post code for it...

Digital video is far, far more difficult. The bandwidth is enormous and often advanced, high computation compression is involved.
Microchip has had a line of cheap 16-bit DSP parts for awhile now. I love the 33F series. Microchip has good support and a user forum.
Oznog said:Microchip's https://www.microchip.com of course. Look up the 33F series (3.3V-only though). These can do 40 million instructions per second and this is a 16-bit core, the working regs are 16 bit and all the math ops work on 16-bit operands. There's also two 40-bit Accumulator with a set of accumulator-specific asm operations.
30F is a somewhat less powerful series which is also pretty power-hungry (electrical power), but it can run on 5v.
You can get expensive demo boards or just get an ICD2 and work with a chip. You can do audio work and control systems. Video, well you can generate text and display it on an NTSC TV set but you're not going to say play a video off a Firewire link to an NTSC TV set even without manipulating the image, that requires far more power.
MATLAB's not really doing a capture. Your hardware dongle or webcam or whatever is doing the capture. For MATLAB to display the picture is a start but hardly what MATLAB is designed for, MATLAB is about manipulating the data with algorithms not just moving it from a capture device to a display device.
An example of video DSP would be to sharpen a blurry image. There are a hundred different algorithms in this area. It would take a very powerful DSP to implement them in real time however and the code would need to be designed and optimized for that processor.
Microchip has a more powerful 32-bit core coming out soon, they've announced it but I don't see any orderable products at this time and no support yet.
