Multimedia data processing elements for digital TV and multimedia services in home server platform

This paper describes the design and implementation of multimedia data processing elements for a home server platform. Generally, a home server can be considered as an integrated form of a multimedia data server, home control server, and home information server. As a multimedia data server, the proposed scheme has a digital TV receiver module and a multimedia codec module. Thus, watching digital TV and remote multimedia services are available in this platform. In addition, an error resilient scheme using digital watermarking is implemented to correct transmission errors in a noisy channel.
