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.

Claims

1. A method, comprising:

identifying media streams from a plurality of input devices;

associating media stream data with their respective media streams by tagging media stream data with associative tags;

processing data from media streams in parallel;

monitoring and saving a media processor state as a media processor switches from processing data from a first media stream to processing data from a second media stream, the media processor in communication with a CPU;

reloading the media processor state associated with the first media stream to the media processor when the media processor switches back to processing data from the first media stream allowing the media processor to resume processing the first media stream;

running system software on the CPU, the system software including at least an operating system.

2. A non-transitory computer-readable medium carrying one or more sequences of instructions, which instructions, when executed by one or more processors, cause the one or more processors to carry out the steps of:

identifying media streams from a plurality of input devices;

associating media stream data with their respective media streams by tagging media stream data with associative tags;

processing data from media streams in parallel;

monitoring and saving a media processor state as a media processor switches from processing data from a first media stream to processing data from a second media stream, the media processor in communication with a CPU;

reloading the media processor state associated with the first media stream to the media processor when the media processor switches back to processing data from the first media stream allowing the media processor to resume processing the first media stream;

running system software on the CPU, the system software including at least an operating system.

3. An apparatus, comprising:

a media stream identification subsystem that identifies media streams from a plurality of input devices;

a media stream data association subsystem that associates media stream data with their respective media streams by tagging media stream data with associative tags;

a CPU, the CPU running system software, the system software including at least an operating system;

a multi channel media stream processor, the multi channel media stream processor processes data from media streams in parallel the multi channel media stream processor in communication with the CPU;

a processor state monitor that monitors and saves state of the multi channel media stream processor as the multi channel media stream processor switches from processing data from a first media stream to processing data from a second media stream, when the multi channel media stream processor switches back to processing data from the first media stream, a multi channel media stream processor state associated with the first media stream is reloaded to the multi channel media stream processor and the multi channel media stream processor resumes processing the first media stream.
