Abstract
A delay detector detects a reproduction delay for a video signal based on a delay notification communicated from a manager to manage the reproduction delay using a state variable. A controller conducts delay recovery control by forcing an image quality improving unit to omit filtering based on the state variable or switching the type of filtering to a simpler one, while avoiding the need to omit decoding of a frame (i.e., frame skipping). This results in a reduction in a load on a processor and recovery of the reproduction delay.
Claims26
A method for reproducing an encoded video signal, the method comprising:
- decoding the encoded video signal to produce a decoded video signal;
- detecting a reproduction condition;
- and
- processing the decoded video signal based on the reproduction condition.
An apparatus for reproducing an encoded video signal, the apparatus comprising:
- a decoder configured to decode an encoded video signal;
- at least one filter configured to filter the decoded video signal;
- a detector configured to detect a reproduction condition;
- and
- a controller configured to control said at least one filter based on the detected reproduction condition.
An article of manufacture comprising a computer usable medium having computer readable program code means embodied therein for reproducing an encoded video signal, the computer readable program code means comprising:
- first computer readable program code means for causing a computer to decode the encoded video signal;
- second computer readable program code means for causing the computer to perform a filter processing on the decoded video signal;
- third computer readable program code means for causing the computer to detect a reproduction condition;
- and
- fourth computer readable program code means for causing the computer to control the filter processing based on the detected reproduction condition.
