Abstract

A method for managing the detection of advertising sequences in a stream of information stored on a mass memory module of an electronic apparatus, the information stream corresponding to an extract of a television program, the information stream including a first set of information corresponding to a content to be rendered and a second set of information, corresponding to the advertising sequences, the information stream including at least one set of video information, and teletext type data, and subtitle data associated with the stream, the method including analyzing the video information for detecting a format transition in the images associated with the video information; optionally storing a first address information corresponding to the detected transition, and validating a first detection condition; analyzing the teletext type data for detecting an absence, and then a presence, of teletext subtitles associated with the video information, optionally storing a second address information corresponding to the detected, transition, and validating a second detection condition; analyzing the subtitle data associated with the stream for detecting an absence, then a presence of the subtitle data associated with the stream; optionally storing third address information corresponding to the detected transition, and validating a third detection condition; if the three detection conditions are validated, identifying the stored address information as transition sequences between the second set of information and the first set of information.

Claims

1. A method for managing the detection of advertising sequences in a stream of information stored on a mass memory module of an electronic apparatus, said information stream corresponding to an extract of a television program, said information stream including a first set of information corresponding to a content to be rendered and a second set of information, corresponding to said advertising sequences, said information stream including at least one set of video information, and teletext type data, and subtitle data associated with the stream,

said method comprising:

analyzing the video information for detecting a format transition in the images associated with the video information;

optionally storing a first address information corresponding to the detected transition, and validating a first detection condition;

analyzing the teletext type data for detecting an absence, and then a presence, of teletext subtitles associated with said video information optionally storing a second address information corresponding to the detected transition, and validating a second detection condition;

analyzing the subtitle data associated with the stream for detecting an absence, then a presence of said subtitle data associated with the stream;

optionally storing third address information corresponding to the detected transition, and validating a third detection condition;

if the three detection conditions are validated, identifying the stored address information as transition sequences between the second set of information and the first set of information.

2. The method according to claim 1 wherein the stored address information corresponding to an actual transition sequence is that associated with a video image to be rendered first.

3. The method according to claim 1, comprising pursuing an operation started beforehand, of reading the considered stream of information at the stored address information.

4. The method according to claim 1, wherein the format transition in the images associated with said video information is a transition from a 4/3 type format to a 16/9 type format.

5. The method according to claim 1, wherein analyzing the video information is carried out linearly or by dichotomy.

6. The method according to claim 1, wherein analyzing the teletext type data is carried out linearly.

7. The method according to claim 1, wherein analyzing subtitle data associated with the stream is carried out linearly, or by dichotomy.

8. The method according to claim 1, comprising receiving an instruction from a user for triggering said method prior to analyzing the video information.

9. The method according to claim 8, wherein the information stream in which the detection of advertising sequences is managed corresponds to a video information duration determined beforehand, and wherein, in the absence of validated detection conditions, the method comprises issuing a warning message.

10. The method according to claim 9, wherein the information stream in which the detection of advertising sequences is managed starts at an image viewed by the user when said user issues the instruction for triggering said method.

11. The method according to claim 1, wherein said method is implemented automatically.

12. The method according to claim 11, wherein the automatic implementation is periodic.

13. An electronic apparatus capable of implementing the method according to claim 1.

14. The electronic apparatus according to claim 14, wherein said apparatus is a digital television decoder type electronic apparatus.
