Abstract

A system, method, and computer program product are provided for validating an aspect of media data processing utilizing a signature. In use, media data is received in a system. Additionally, at least one signature of at least a portion of the media data is generated. Furthermore, at least one aspect of processing of the media data by the system is validated utilizing the at least one signature.

Claims

1. A method, comprising:

receiving media data in a system;

identifying a portion of the media data using commands incorporated in content of the media data;

generating at least one signature of the portion of the media data; and

validating at least one aspect of processing of the media data by the system utilizing the at least one signature, where the validating includes determining whether the processing of the media data by the system has changed one or more elements of the media data;

wherein for each of the commands, the command is incorporated by setting a color value associated with at least one pixel of the content of the media data, and wherein the color value is predetermined to reflect the command such that the command is identified upon encountering the at least one pixel having the color value indicative of the command.

2. The method of claim 1, wherein the at least one signature is generated for at least one frame of the portion of the media data.

3. The method of claim 2, wherein a first signature is generated for a first color component of the frame, a second signature is generated for a second color component of the frame, and a third signature is generated for a third color component of the frame.

4. The method of claim 1, wherein a single signature is generated for each frame of the portion of the media data.

5. The method of claim 4, wherein the single signature reflects all color components of the frame.

6. The method of claim 4, wherein the single signature reflects only a subset of color components of the frame.

7. The method of claim 1, wherein the validating includes comparing the at least one signature with at least one other signature determined for the portion of the media data prior to any processing of the media data by the system.

8. The method of claim 7, wherein if the at least one signature and the at least one other signature match, then it is determined that the one or more elements of the media data have not changed.

9. The method of claim 1, wherein the commands include a start command indicating a start of the portion of the media content and a stop command indicating an end of the portion of the media data.

10. A computer program product embodied on a non-transitory computer readable medium, comprising:

computer code for receiving media data in a system;

computer code for identifying a portion of the media data using commands incorporated in content of the media data;

computer code for generating at least one signature of the portion of the media data; and

computer code for validating at least one aspect of processing of the media data by the system utilizing the at least one signature, where the validating includes determining whether the processing of the media data by the system has changed one or more elements of the media data;

wherein for each of the commands, the command is incorporated by setting a color value associated with at least one pixel of the content of the media data, and wherein the color value is predetermined to reflect the command such that the command is identified upon encountering the at least one pixel having the color value indicative of the command.

11. An apparatus, comprising:

an interface receiver for receiving media data from a system; and

at least one of hardware and software for identifying a portion of the media data using commands incorporated in content of the media data and generating at least one signature of the portion of the media data;

wherein at least one aspect of processing of the media data by the system is validated utilizing the at least one signature, where the validating includes determining whether the processing of the media data by the system has changed one or more elements of the media data;

wherein for each of the commands, the command is incorporated by setting a color value associated with at least one pixel of the content of the media data, and wherein the color value is predetermined to reflect the command such that the command is identified upon encountering the at least one pixel having the color value indicative of the command.

12. The apparatus of claim 11, wherein the system includes a processor coupled to memory via a bus.
