System and method for selective recording of information
First Claim
1. A system for controlling a recording device to effect selective recording of an incoming information stream, wherein the incoming information stream comprises multiple media frames, the system comprising:
- a memory; and
control logic in communication with the memory configured to;
define a segment of interest in a first information stream, wherein the segment of interest comprises multiple media frames;
modify the segment of interest by adding a selected media frame of the multiple media frames to the segment of interest or deleting a selected media frame of the multiple media frames from the segment of interest;
mark as a boundary point a media frame adjacent to a selected media frame, wherein the selected media frame is to be deleted from the segment of interest;
prevent the addition of media frames to a terminal portion of the segment of interest which has been marked by the boundary point;
generate multiple statistical vectors corresponding to individual media frames in the segment of interest;
store the generated multiple statistical vectors in the memory;
perform sequential pattern matching of the incoming information stream based on the multiple statistical vectors; and
generate a signal for the recording device to effect control of the recording device with respect to the incoming information stream based on the sequential pattern matching.

Abstract
A system and method for selective recording of information uses sequential pattern matching of statistical vectors which characterize incoming time-based information to identify previously marked information within an incoming information stream. The system and method generate a signal to control a recording device to either elide the previously marked information from the recording, or to begin recording once the previously marked information is identified, depending upon the current mode of operation. The system and method may be utilized to omit recording of unwanted information, such as commercials in a television broadcast, or to automatically locate desired information on any of a number of available information channels without a priori knowledge of the occurrence time or channel of the information.

8. A method for controlling a recording device to effect selective recording of an incoming information stream, wherein the incoming information stream comprises multiple information frames, the method comprising:
-
defining a segment of interest in the incoming information stream, wherein the segment of interest comprises multiple information frames; modifying the segment of interest by adding a selected media frame of the multiple media frames to the segment of interest or deleting a selected media frame of the multiple media frames from the segment of interest; marking mark as a boundary point a media frame adjacent to a selected media frame, wherein the selected media frame is to be deleted from the segment of interest; preventing the addition of media frames to a terminal portion of the segment of interest which has been marked by the boundary point; generating statistical vectors corresponding to individual information frames in the segment of interest; storing the generated statistical vectors; performing sequential pattern matching of the incoming information stream to the stored statistical vectors; and generating, and outputting to the recording device, a signal based on the sequential pattern matching for the recording device to effect control of the recording device with respect to the incoming information stream. - View Dependent Claims (9, 10, 11, 12)
