Filter module for a video decoding system
View Patent ↗Systems and methods are disclosed for filter modules in a video display system or network. One embodiment relates to a method for operating a filter module in a video display network comprising determining a picture type, display type and operation of the display network. The method further comprises determining, in real time, a filter configuration from a plurality of possible filter configurations based on the determined picture type, display type and operation.
1. A method of operating a filter module a in a video display system, said method comprising:
determining a picture type of a plurality of video streams;
determining a display type of at least one display device; and
determining in real time, a plurality of simultaneous filter configurations, wherein each of the corresponding plurality of filter configurations are for a particular one of the plurality of video streams, wherein each of the plurality of filter configurations are based at least in part on the picture type of the particular one of the plurality of video streams and the at least one display device; and
simultaneously outputting each of the plurality of video streams filtered by the plurality of filter configurations.
2. The method of claim 1 , wherein determining the picture type of the plurality of video streams further comprises determining if the picture type is frame based video, field based video, or graphics.
3. The method of claim 1 , wherein determining a display type of the at least one display device comprises determining if said at least one display type is progressive or interlaced.
4. The method of claim 1 , further comprising:
determining whether an interpolation or a decimation, operation are to be performed on each of the plurality of video streams; and
wherein determining in real time, a plurality of filter configurations is also based at least in part on whether the interpolation or decimation operations is to be performed on the particular one of the plurality of video streams.
5. The method of claim 1 , wherein each of the plurality of filter configurations are determined in accordance with at least one register write instruction.
6. The method of claim 1 , wherein the at least one display further comprises a plurality of simultaneous displays, wherein each of the plurality of simultaneous displays are associated with a particular one of the video streams, and wherein the plurality of filter configurations are also determined based at least in part on the display type of the one of the plurality of simultaneous displays that is associated with the particular video stream.
