Abstract

A multimedia player and method is disclosed for displaying multimedia content on a video screen. A video stream and a markup language segment associated with the video stream are received, wherein the markup language segment comprising a time stamp identifying a target segment of the video stream, and at least one keyword associated with the time stamp. The keyword is transmitted over a network to a search engine, and related content is received from the search engine over the network, wherein the related content is related to the keyword. When the target segment of the video stream is displayed on the video screen, the related content is concurrently displayed on the video screen.

receiving a video stream and a markup language segment associated with the video stream, the markup language segment comprising;

a time stamp identifying a target segment of the video stream; and

at least one keyword associated with the time stamp;

transmitting the keyword over a network to a search engine;

receiving related content from the search engine over the network, wherein the related content is related to the keyword; and

when the target segment of the video stream is displayed on the video screen, concurrently displaying the related content on the video screen.

19. The multimedia player as recited in claim 18, wherein the markup language segment further comprises a pointer to a next markup language segment to process.

20. The multimedia player as recited in claim 18, wherein the time stamp comprises an offset from the start of the video stream to the beginning of the target segment.

21. The multimedia player as recited in claim 18, wherein the time stamp comprises a duration of the target segment.

22. The multimedia player as recited in claim 18, wherein the related content comprises advertising content.

23. The multimedia player as recited in claim 18, wherein the related content comprises news content.

24. The multimedia player as recited in claim 18, wherein the search engine performs a search of the Internet based on the keyword to locate the related content.

25. The multimedia player as recited in claim 18, wherein the control circuitry receives the video stream and markup language segment over a network.

26. The multimedia player as recited in claim 18, wherein the control circuitry receives at least one of the video stream and the markup language segment from a local storage device.

27. The multimedia player as recited in claim 18, wherein the control circuitry receives the video stream over a first channel, and receives the markup language segment over a second channel.

28. The multimedia player as recited in claim 18, wherein the control circuitry receives the video stream over a first channel, and receives the markup language segment over the first channel.
