Abstract

One aspect of the invention is directed to a system and method for video cataloging. The video is cataloged according to predefined or user definable metadata. The metadata is used to index and then retrieve encoded video.

Claims

1. A video cataloger system, comprising:

a video cataloger receiving video information and a plurality of time codes associated with the video information, and concurrently generating a plurality of digital metadata tracks indicative of the video information and the time codes;

a plurality of video encoders, each encoder receiving the video information and generating a type of encoded digital video data indicative of the video information;

a digital metadata track server receiving the digital metadata tracks from the video cataloger and providing network access for client computers; and

a content server receiving the encoded digital video data from at least one of the video encoders and providing network access for client computers, wherein the content server receives requests from the digital metadata track server to send encoded digital video data to a selected one of the client computers;

wherein the video cataloger controls the video encoders to start and stop encoding and stores the start time of each encoder so that the time codes associated with the digital metadata tracks and the stored start times permit selective access to the encoded digital video data.

2. The system of claim 1, wherein the video information is provided by a videotape deck.

3. The system of claim 1, wherein the video information is provided by a live satellite feed.

4. The system of claim 1, wherein the video encoders include at least one encoder to generate digital data encoded to a Moving Picture Experts Group (MPEG) standard.

5. The system of claim 1, wherein the video encoders include at least one streaming video encoder.

6. The system of claim 1, wherein the video cataloger and the encoders each reside on individual computers, the computers being connected in a computer network.

7. The system of claim 1, wherein the digital metadata tracks include one or more of the following:

keyframe, close caption text, audio class, speech, speaker identification, keyword and clip.

8. The system of claim 1, wherein the video information time codes are Society of Motion Picture and Television Engineers (SMPTE) time codes.

9. The system of claim 1, wherein the video information is received from a digital source.
