Abstract
Systems and methods that manipulate a system time clock in an audio decoding system and/or a video decoding system are disclosed. In one example, the method may include the steps of selecting a trick mode rate and adjusting system time clock update rate as a function of the selected trick mode rate.
Claims27
A method for providing a trick mode in a personal video recording system, comprising the steps of:
- selecting a trick mode rate;
- and
- adjusting a system time clock (STC) update rate as a function of the selected trick mode rate.
A method for providing a trick mode in a personal video recording system, comprising the steps of:
- measuring depths of a buffer over a particular time period;
- determining differences between the measured depths of the buffer and a desired depth of the buffer;
- processing the determined differences;
- and
- modifying an STC update rate as a function of the processed differences.
