1. A method for detecting commercials in a compressed video stream, the method comprising the steps of:
- compressing video data and generating compressed video data;
detecting a plurality of separators based on said generated compressed data, each of said separators is defined by at least two consecutive scene changes;
determining the beginning and ending of a commercial break among said plurality of separators by comparing a gap between said plurality of separators.

Abstract
A method and device for detecting commercials using the encoding parameters of a compressed video stream is provided. A video encoder receives uncompressed video data and generates a compressed video data. A plurality of separators, each defined by at least two consecutive scene changes in a sequence of the compressed video data, is detected. Then, the beginning and ending of a commercial break is derived by comparing the gap between these separators to a predetermined threshold value.

7. A method for detecting commercials in a compressed video stream, the method comprising the steps of:
-
encoding incoming video data received from a transmitting source to generate compressed video data;
detecting a plurality of separators in said compressed video data, each of said plurality of separators including at least two consecutive scene changes according to said compressed video data;
determining the beginning and ending of a commercial break by comparing a gap between said plurality of separators to a predetermined threshold value;
identifying one of said separators as the beginning of a commercial break when the gap between said one separator and a previous separator is greater than said predetermined threshold value; and
,identifying one of said separators as the ending of a commercial break when the gap between said one separator and a next separator is greater than said predetermined threshold value. - View Dependent Claims (8, 9)

10. An apparatus for detecting commercials in a compressed video stream, comprising:
-
a video encoder for receiving uncompressed video data and generating compressed video data;
a detector for detecting a plurality of separators in said compressed video data;
a processor configured to edit said compressed video data by identifying the beginning and ending of a commercial break in said compressed video data; and
,a playback selector for editing said compression video data to skip said commercial break for a subsequent viewing. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
