Abstract
A video processing apparatus can receive video at two different rates, which may be High Definition video and Standard Definition Video. The input video is stored and read into a processor at a fixed internal rate for processing at that rate. Processed video is output to a further store from which it can be read at either of the input rates.
Claims31
Video processing apparatus for processing video conforming to one of a plurality of video standards at an internal rate independent of a standards data rate associated with the video data, the apparatus comprising:
- input storage for storing video data, capable of being written to in each of a plurality of video standards;
- and
- a video processor for reading stored video data from the input storage and processing the video data at said internal rate independent of the standards data rate.
Video processing apparatus for processing video data conforming to one of a plurality of video standards, the apparatus comprising:
- input storage for storing video data;
- video processor for reading stored video data from the input storage and processing the video data at an internal rate independent of the standards data rate;
- and
- output storage for storing processed video data generated by the video processor at an internal rate independent of the standards data rate.
A method of processing video data conforming to one of a plurality of video standards at an internal rate independent of a standards data rate associated with the video data, the method comprising:
- storing video data in video data storage in each of a plurality of video standards;
- reading stored video data;
- and
- processing in a video data processor the read video data at an internal rate independent of the standards data rate.
A method of processing video data conforming to one of a plurality of video standards, the method comprising:
- storing video data in input video data storage;
- reading stored video data from the input video data storage;
- processing the video data at an internal rate independent of the standards data rate;
- and
- storing processed video data in output video data storage at an internal rate independent of the standards data rate.
Video processing apparatus comprising:
- a plurality of video processors for processing video data;
- and
- a router for routing video data between a first and at least a second of said plurality of video processors at an internal rate independent of a standards data rate associated with the video data.
Video processing apparatus comprising:
- an input adapted to receive input video data at a first rate and input video data at a second rate, different to said first rate;
- an input store, adapted to read input video data at both said first and second rates from said input;
- a processor adapted to read video data from said input store at a common fixed rate, and to process said read data at said common fixed rate;
- an output store adapted to store video data output from the processor;
- and
- an output capable of reading from said output store at both said first and said second rates.
A method of processing video data, the method comprising:
- receiving input video data at a first rate and input video data at a second rate, different to said first rate;
- writing, at both said first and second rates, input video data to an input video store;
- reading video data from said input store at a common fixed rate;
- processing said data read from said input store at said common fixed rate;
- writing said processed video data to an output video store at said common fixed rate;
- and
- reading video data from said output store at either or both of said first and said second rates
