Multimedia signal processing system
First Claim
1. A method, comprising:
- receiving a plurality of media stream data portions via at least one input source;
identifying media streams in the plurality of media stream data portions;
associating each portion of media stream data received with its respective media stream by tagging each portion of media stream data with associative tags;
processing media stream data from media streams in parallel, a media processor switching between processing media stream data from a first media stream to processing media stream data from a second media stream, the media processor in communication with a CPU;
running system software on the CPU, the system software including at least an operating system.

Abstract
A multimedia signal processing system utilizes an easily manipulated, low-cost storage and display system that allows the user to view a television program and instantly review previous scenes within the program. The invention also allows the user to store selected programs while simultaneously watching or reviewing another. A versatile system architecture enables providing the invention in multiple configurations, each adapted to receive input signals from a different source. At the highest level, the system includes an input section and an output section. Across all configurations, the output section remains substantially the same, while the input section varies according to the signal type and the source. Thus, several configurations are provided, each one requiring only minor system board modifications. The system architecture thus simplifies the design and manufacturing challenge presented by producing units to serve different markets, such as digital satellite, digital cable and analog cable.
