Digital video: Algorithms & interfaces

Digital video technology is no longer restricted to broadcast studios: It is available to practitioners of computer graphics, and it is converging - or colliding! - with mainstream computing. This course details the algorithms and interfaces used for high-quality digital video. We describe the sampling, quantization, and filtering that take place in high-quality digital video. We describe the algorithms used for chroma subsampling, spatial resampling, deinterlacing, frame rate conversion, and other processes necessary to exchange digital video data between broadcast, consumer, and computer graphics domains. We detail the digital video interfaces used in the broadcast studio.

Prerequisites

You should have some familiarity with digital video, and have no fear of mathematics. You should have detailed knowledge of image coding, perhaps gained by attending this year's Color Image Coding course.

Topics beyond the prerequisites

Studio video interfaces and emergent consumer DVC, DVD, and HDTV equipment retains some features of broadcast studio video that are undesirable to computing: interlace, 4:1:1 chroma subsampling, and nonsquare pixels. If you are a computer programmer or a hardware designer wishing to integrate video into the computer environment, you will have to become familiar with the algorithms of sample rate conversion (in video, called interpolation), and spatial resampling. We will explain these techniques, and describe the underlying mathematics.
