Abstract
A video stream is received at an input. The video stream is recorded to a storage unit. While the video stream continues to be recorded, a portion of the video stream is retrieved from the storage unit and provided at an output. In one embodiment, the storage medium is a random access storage unit, such as a hard disk.
Claims14
A method of displaying a video stream comprising the steps of:
- (a) receiving the video stream at an input;
- (b) initiating one or more stores of the video stream into a storage unit;
- (c) initiating one or more random access reads of the video stream from the storage unit, wherein the one or more stores of the step (b) are multiplexed with the one or more reads of the step (c);
- and
- (d) displaying the video stream.

A method of displaying a video stream, the method comprising the steps of:
- (a) receiving the video stream;
- (b) storing the video stream received in the step (a) to a storage unit;
- and
- (c) displaying the video stream at least initially delayed by a time delay, wherein when the time delay is greater than a predetermined threshold the video stream is displayed from the storage unit, and wherein when the time delay is less than the predetermined threshold the video stream is displayed from the video stream received in the step (a).

A method of recording a video stream, the method comprising the steps of:
- (a) receiving the video stream;
- (b) displaying the video stream as it is received;
- (c) responsive to a first user input, suspending display of the video stream and storing to a storage medium the video stream received subsequent to the first user input;
- (d) reading the video stream from the storage medium to provide the video stream at the output;
- and
- (e) wherein the video stream read in step (d) corresponds to the video stream received in step (a) shifted by time delay, wherein when the time delay falls below a predetermined amount of time, providing at an output the video stream received in step (a) without first storing the video stream to the storage medium.
