Abstract
An integrated circuit chip configured to be coupled to a single shared memory including, in combination, a memory access module, at least one video signal processing module, and a frame rate converter, wherein the memory access module is configured to coordinate access to the single shared memory by the at least one video signal processing module and the frame rate converter.
Claims16
An integrated circuit chip configured to be coupled to a single shared memory comprising, in combination:
- a memory access module;
- at least one video signal processing module;
- and
- a frame rate converter;
- wherein the memory access module is configured to coordinate access to the single shared memory by the at least one video signal processing module and the frame rate converter.
A digital television receiver comprising:
- a memory;
- a single integrated circuit chip comprising, in combination:
- a memory access module;
- at least one video signal processing module;
- and
- a frame rate converter;
- wherein the memory access module is configured to coordinate access to the memory by the at least one video signal processing module and the frame rate converter.
A method of processing video signals in a receiver, the method comprising:
- accessing a single memory from a single integrated circuit chip for use in processing video signals including frame rate conversion of the signals;
- and
- coordinating access to the single memory for frame rate conversion of the video signals and at least one of decoding, deinterlacing, and scaling the video signals.
