Data Compression Systems for Home-Use Digital Video Recording

Newly developed communication-and information networks offer a large number of services which make use of image data, leading to an increasing demand for image storage systems. This paper focuses on a new emerging technology, namely image data compression techniques for digital recording. image coding for storage equipment covers a large variety of systems because the applications differ considerably in nature. In this paper, video coding systems suitable for digital TV and HDTV recording and digital electronic still picture storage are considered. In addition, attention is paid to picture coding for interactive systems, such as the compact-disc interactive system. The relation between the recording system boundary conditions and the applied coding techniques is outlined. The main emphasis is on picture coding techniques for digital consumer recording.
