Abstract

A computer based television signal recording device is provided. This recording device allows for the recording of input streams onto a mass storage device such as a computer hard drive. The playback of individual programs can be done independently of the recording. A user interface is provided which has a list of the recorded television signals and the user can select for playback any of the listed recorded television signals.

Claims

1. A method of recording and playing back in a multimedia device an audio and video stream of data comprising the steps of:

accepting at least one audio and video stream of data transmitted via a communication system to said multimedia device;

buffering said accepted at least one audio and video stream of data;

controlling, the storage of said at least one audio and video stream of data into a random access mass storage device, the so buffered audio and video stream of data into a the random access mass storage device, under the control of a micro-processor such that multiple audio and video streams of data are stored on said random access mass storage device and wherein any given stored audio and video stream so stored is individually retrievable from the random access mass storage device;

automatically creating a selection list of the plurality stored multiple audio and video streams;

providing a user controllable signal to said micro-processor to select among the so listed multiple audio and video streams so as to play back at least one of said store audio and video streams of data stored in said mass storage device in response to a user signal;

wherein the play back is of an individually retrievable one of said at least one of said stored audio and video stream of data and such that a play back of a so selected stored audio and video stream can occur during an accepting, buffering and storing of a combined audio and video stream of data of a different individually retrievable audio and video stream of data, and wherein said different individually retrievable audio and video stream of data is different from, at least relative in time from said played back portion of the combined video and audio stream of data and wherein the creation of the selection list of said stored plurality of audio and video streams is performed by said micro-processor based upon said received audio and video stream.

2. A method as in claim 1 wherein said accepting said at least one audio and video stream is via a digital communications medium.

3. A method as in claim 1 wherein said random access mass storage device is a computer hard disk drive.

5. A method as in claim 3 wherein said random access mass storage device is a computer hard disk drive.

4. A method of recording and playing back, in a multimedia device, an audio and video stream of data comprising the steps of:

selectively controlling via software the acceptance of an audio and video stream of data transmitted from a remote location, via a communication system to said multimedia device;

buffering said accepted audio and video stream of data in random access memory;

controlling the storage of said audio and video stream of data, buffered in said random access memory such that said buffered streams of data are stored on a random access mass storage device, under the control of a micro-processor such that a plurality of stored audio and video streams are stored in as separately retrievable segments;

automatically creating a selection list of the plurality stored multiple audio and video streams

providing a user controllable signal to said micro-processor to play back at least one of said stored audio and video streams of data stored in said random access mass storage device;

wherein a play back of said at least one of said stored audio and video streams of data can occur during the

accepting,

buffering and

storing of a combined video and audio stream of data which is different from said played back combined video and audio stream of data and

wherein said storing and retrieval of said segments is controlled by software;

further wherein said play back is in response to a users signal selecting one of said plurality of stored audio and video streams stored on said random access mass storage device; and

wherein the creation of the selection list of said stored plurality of audio and video streams is performed by said micro-processor based upon said received audio and video stream.

6. A software control method of recording and playing back segments of an audio and video stream of data comprising the steps of:

selectively controlling via software the acceptance of discrete segments of an audio and video stream of data transmitted from a remote location;

buffering said accepted segments audio and video stream of data in random access memory;

controlling the storage of said audio and video stream of data, buffered in said random access memory such that said audio and video stream of data is stored to on a random access mass storage device, under the control of a micro-processor such that a plurality of segments are stored and said stored segments are separately retrievable;

automatically creating a selection list of the each of the separately retrievable segments among the plurality of stored multiple audio and video streams;

providing a signal to said micro-processor to play back at least one of said stored audio and video streams of data stored in said random access mass storage device;

wherein a play back of said at least one of said stored audio and video streams of data can occur during the accepting, buffering and storing of a combined audio and video stream of data and wherein said storing and retrieval of said segments is controlled by software;

wherein said play back is in response to a users signal selecting one of said plurality of stored audio and video streams stored on said random access mass storage device and

wherein the creation of the selection list of said stored plurality of audio and video streams is performed by said micro-processor based upon said received audio and video stream.

7. A method as in claim 6 wherein said random access mass storage device is a computer hard disk drive.
