Abstract

A modular video processing system and methodology for processing a plurality of video assets having different asset properties in real-time to a common format compatible with a display device is described. The system includes a plurality of pipelined video processing modules wherein each operational pipelined video processing module performs a different configurable video processing function on one or more video asset frames. The system also includes a process control module for providing each operational pipelined video processing module with data for configuring the video processing module for a current frame and data for configuring the video processing module for a subsequent frame wherein each configuration is based on one or more asset properties for the video asset being processed. Each pipelined video processing module has a memory location for the configuration for the current frame and a memory location for the configuration for a subsequent frame.

Claims

1. A modular video processing system capable of processing a plurality of video assets having different asset properties in substantially real-time to a format compatible with a display device, the system comprising:

a plurality of pipelined video processing modules wherein each operational pipelined video processing module performs a different configurable video processing function on one or more video asset frames; and

a process control module for providing each operational pipelined video processing module with data for configuring the video processing module for a current frame and data for configuring the video processing module for a subsequent frame wherein each configuration is based on one or more asset properties for the video asset being processed.

2. The modular video processing system according to claim 1 wherein each pipelined video processing module has a memory location for the configuration for the current frame and a memory location for the configuration for a subsequent frame and the pipelined video processor switches between the memory location for the configuration for the current frame and the memory location for the subsequent frame based on a timing signal.

3. A modular video processing system according to claim 1 wherein the process control module calculates one or more operating parameters of the configuration based on the one or more asset properties of the video asset.

4. A modular video processing system according to claim 1, wherein after a first pipelined video processing module processes data for the current frame of a video asset, the first pipelined video processing module passes the processed data to a second pipelined video processing module based on a timing signal.

5. A modular video processing system according to claim 1, wherein the process control module is a central controlling module for two or more video processing modules.

6. A modular video processing system according to claim 1 wherein the process control module pipelines one or more asset properties for each video asset through each of the operational video processing modules.

7. A modular video processing system according to claim 1, wherein the process control module is a centralized control module, the centralized control module processing for each operational pipelined video processing module asset parameters for each video asset defining a configuration for that video asset for the operational pipelined video processing module and wherein the centralized control module provides the configuration to the appropriate operational pipelined video processing module based on the video asset being processed.

8. A modular video processing system according to claim 1, wherein one or more pipelined processing modules receive a current frame for processing from a previous pipelined processing module at a top of frame period.

9. A modular video processing system according to claim 1, wherein a pipelined video processing module may by operational or idle.

10. A modular video processing system according to claim 9, wherein if a processing module is idle, the process control module does not provide that pipelined video processing module with configuration data.

11. A modular video processing system according to claim 1, wherein the pipelined video processing modules outputs processed data to a display device at a frame period rate.

12. A modular video processing system according to claim 1, wherein each processing module can be reconfigured in real-time when frame processing periods change, since a configuration for the subsequent frame is already stored in associated memory of the pipelined video processing module.

13. A modular video processing system according to claim 1, wherein each pipelined video processing modules receive a repeating frame timing signal and data processed for the current frame in a first pipelined video processing module is forwarded to a second video processing module when the frame timing signal repeats.

14. A modular video processing system according to claim 1, wherein the pipelined processing modules decompresses each frame of a video asset.

15. A modular video processing system according to claim 1 wherein the plurality of pipelined video processing modules includes an entropy decoder module, a dequantizer module, and an inverse transform module.

16. A modular video processing system according to claim 1, wherein the process control module is localized to two or more processing modules and the system further includes a centralized processing control module that communicates with each of the process control modules over a bus.

17. A modular video processing system according to claim 1, wherein data determined by a first processing module is fed forward to a subsequent processing module for determining operating parameters for configuration of the subsequent processing module.

18. A method for processing a plurality of video assets having different asset properties in substantially real-time to a format compatible with a display device, the method comprising:

obtaining a play list of the plurality of video assets to be displayed on a display device;

sequentially retrieving each video asset listed in the play list from a memory location;

processing each video asset to a format that is compatible with the display device; and

output the processed sequential video assets to the display device;

wherein each video asset is processed and displayed in substantially real-time.
