Abstract

In one embodiment, a method is illustrated as including generating tagging data using a computer system to tag certain portions of digital content for playing at a normal rate and inserting the tagging data into a field of a data packet to create tagged digital content. In another embodiment, a further method is illustrated as including generating a metadata file using a computer system to denote certain portions of digital content for playing at a normal rate and inserting the metadata file into a media stream containing the certain portions of digital content. Additionally, in a further embodiment, a system is illustrated as including a generator residing on a device to generate tagging data to tag certain portions of digital content for playing at normal rate and an inserter residing on the device to insert the tagging data into a field of a data packet to create tagged digital content.

5. The method of claim 1, wherein the playing of the digital content at the expedited rate occurs during a reverse mode.

6. The method of claim 1, wherein the tagged portions of the digital content to be played at the normal rate comprise an audio portion of the digital content to be played at the normal rate and a corresponding video portion to be played at the expedited rate.

7. The method of claim 1, wherein the tagged portions of the digital content to be played at the normal rate comprise a video portion of the digital content to be played at the normal rate and a corresponding audio portion to be played at the expedited rate.

8. The method of claim 1, wherein the tagged portions of the digital content to be played at the normal rate comprise both a video portion and a corresponding audio portion to be played at the normal rate.

9. A computer-implemented method comprising:

receiving tagged digital content at a device having a media player residing thereon, the tagged digital content indicating a portion of the tagged digital content to be played at a normal rate during playing of the tagged digital content at an expedited rate;

playing the tagged digital content at the expedited rate, the playing is conducted by the media player reading the portions of the tagged digital content at a certain number of Frames Per Second (FPS) considered to be the expedited rate;

reading the tagged digital content to determine whether a specific Temporal Reference (TR) value has been encountered; and

playing the portion of the tagged digital content at the normal rate based on the specific TR value being encountered during the playing of the tagged digital content at the expedited rate, the portions being a segment of the tagged digital content.

10. A computer-implemented method comprising:

generating, using a processor of a machine, tagging data to be matched with certain portions of digital content for playing at a normal rate during playing of the digital content at an expedited rate, the playing is conducted by a media player, residing on a device, that reads the tagged portions of the digital content at a certain number of Frames Per Second (FPS) considered to be the normal rate during the playing of the digital content at the expedited rate, the tagged portions each being a segment of the digital content; and

storing the tagging data into a file.

11. The method of claim 10, wherein the tagging data is one of a group of data types selected from the group consisting of a bit flag and a range of Temporal Reference (TR) values.

12. The method of claim 10, wherein the digital content contains data packets with header types selected from the group of header types consisting of a Real-Time Transport Protocol (RTP) header, a Motion Picture Experts Group (MPEG) video specific header, and a MPEG audio specific header.

13. A computer-implemented method comprising:

receiving a file containing tagging data at a device having a media player residing thereon;

extracting, using a processor of a machine, the tagging data from the file;

inserting individual values of the tagging data into a lookup table as a tagging data value to be used to determine data packets to be viewed at a normal rate that is considered to be a certain number of Frames Per Second (FPS) during playing of digital content at an expedited rate;

retrieving the digital content in a form of a plurality of data packets, wherein the digital content is retrieved separately from the file containing the tagging data;

playing the digital content at the expedited rate, the playing is conducted by the media player reading portions of the digital content at a certain number of FPS considered to be the expedited rate;

looking for a match between a Temporal Reference (TR) value in a data packet and the tagging data value contained in the lookup table; and

playing a segment of the digital content corresponding to the matching TR value at a normal rate during the playing of the digital content at the expedited rate, the playing being conducted using the media player.

14. The method of claim 13, wherein the file containing tagging data is generated at a first device using a first interface, and communicated to the device having the media player, the device retrieving the digital content separately from the file.

15. A system comprising:
