When designing a video AGC, I have read people use the back porch of the video signal as a reference and amplify accordingly. My question is, how can you know what the level of the back porch is in the first place? Firstly, I imagine the color information must first be filtered out, to get rid of the color burst on the back porch (right?). But what is next to determine the back porch level. Do y...

I've just spent over two weeks getting ready to do my next video. It was a combination of one of those vast underestimations one occasionally makes, combined with falling into a bit of an obsession. I am, at this point, not only wondering if it was worth it, but questioning my sanity in carrying on even when the going went beyond tough to just plain crazy. At any rate, a good video ...

Hi friends ! Iam trying to project the performance of our video processing algorithm objectively in terms of PSNR and SSIM. We are dealing with YV12 videos. Iam using the MSU Video Quality measurement tool to compute the PSNR and SSIM values.

Dear All, I plan to implement an wireless emulator for video transmission. The emulator will be real time like normal TV viewing. My rough idea is this video to PC --> DSP --> ethernet daughter card --> ethernet --> another PC for viewing video where the DSP (like C6713) emulates the wireless channel & calculate SNR & map it to BLER from pre simulater link level curves & corrupts vid

Hi: I=2E Audio vs. Video Digitized (mono) audio has a single sample per each sampling interval. In the case of digital video, we could treat each individual sample point location in the sampling grid (each pixel position in a frame) the same way as if it was a sample from an individual (mono) audio signal that continues on the same position in the next frame. For example, a 640=D7480...
