Abstract

A system and method for interactive events relating to broadcast content, whether provided over the television, internet, or other means, provides messages that can be transmitted to different types of user devices, including personal computers, set top boxes, net top boxes, and wireless clients. The system can be used with personal recorders by recording interactive content for display with the broadcast when the recorder is used to play back the broadcast.

Claims

each local storage device receiving and storing the broadcast event in a first data store as the broadcast event is being broadcast via a broadcast event signal to the plurality of remote viewers during a first time period;

each PIR coupled to the local storage device receiving one or more trigger messages from a server system separately from the broadcast of the broadcast event and not embedded in the broadcast event signal, the trigger messages identifying interactive content for display by the client devices during a first time period in response to the one or more trigger messages, the interactive content being related to the broadcast event;

each PIR associating the trigger messages received from the server system to the broadcast event and storing the associated trigger messages in a second data store of the corresponding client device; and

during playback of the stored broadcast event by a particular one of the client devices during a second time period, retrieving the stored broadcast event from the first data store and the stored trigger messages from the second data store for providing to the user the interactive content identified by the retrieved trigger messages at one or more times during the retrieved broadcast event when the interactive content would have been displayed when the broadcast event was being broadcast during the first time period, wherein the interactive content includes trivia questions, the PIR stores a correct answer, and responsive to an answer received from a user during playback, the PIR provides to the user an indication of a correct or incorrect answer.

2. The method of claim 1, wherein the local storage device includes fast forward, rewind, and pause functions.

3. The method of claim 1, wherein the associating includes associating information about the broadcast event to the trigger messages, the information being selected from a group consisting of absolute time codes, relative time codes, and frame sequence numbers.

4. The method of claim 1, wherein the first data store and the second data store reside in a same storage medium.

5. The method of claim 1, wherein the PIR uses the processing and storing functionality of the local storage device.

6. The method of claim 1, wherein the local storage device includes a hard drive.

7.

11. The method of claim 1 further comprising:

receiving a user interaction from the particular one of the devices during playback of the interactive content, wherein the interactive content is a poll question and the user interaction is a response to the poll question, wherein the poll response transmitted during the playback of the interactive content is ignored by the server system in calculating a poll result.

12. The method of claim 1, wherein the broadcast event is broadcast of a video program that contains no embedded triggers associated with the interactive content.

13. The method of claim 12, wherein the interactive content is transmitted by the server system over a wide area network concurrently with the video program, wherein the interactive content is synchronized with the video program.
