Abstract

A real time interactive video system for use in real time broadcasts as well as video on demand systems which requires no modification of a television set. In a real time broadcast application, the video content is broadcast for playback on a conventional television or monitor. Frames are extracted from the video content in predetermined time intervals, such as one second intervals, and stored in a directory on an Internet server. For example, for a 30 frame per second video source, one frame of every 30 is extracted and stored as a still image along with linked video files which link pixel objects with the stored frames to data objects, or other resource platforms. In order to synchronize the stored frames and linked video files with the real time video content broadcast, each frame is either numbered sequentially, or referenced by the time code of the frame from which it was extracted. Interactivity with the real time video content broadcast in real time is provided by way of a viewer interaction platform, for example, a computing platform, such as a personal computer or a set top box, or a wireless platform, such as personal digital assistant (PDA) or cell phone, such as a 3G cell phone, linked to the Internet server which hosts the stored frames and linked video files. In accordance with an important aspect of the invention, a video frame interaction application, resident on the view interaction platform, allows a viewer to select specific frames from the video content, as it is broadcast and stores these frames in the memory of the viewer interaction platform. If the viewer interaction platform has limited memory, an Internet link to the image can be saved. The frames are chosen by activating an “entry key” on the view interaction platform. The user selection is either sent to the website for immediate retrieval of the selected frame, or alternatively, the requested linked is saved for later access to the website. The website, upon request, sends the selected frame to the video frame interaction application which allows the viewer to access pixel objects and link to other resource platforms.

Claims

1. A real time interactive video system comprising:

a server for storing a sequence of frames of video content in a frame buffer;

a viewer interaction platform which includes a system for identifying frames of said sequence of frames of video content selected by a user by way of timing signals defining a timed request and exporting said timed requests to said server, said server including a system for comparing said timed requests with said stored video frames and exporting said video data to said viewer interaction application on said device which corresponds to said timed requests for interaction with pixel objects in said video content; and

a timing device for providing said timing signals to said server, said timed signals being synchronized to a real time broadcast of said video content.

2. The real time interaction system as recited in claim 1, wherein said timing signals are time stamps.

3. The real time interaction system as recited in claim 1, wherein said video frames are stored sequentially in said video buffer.

4. The real time interaction system as recited in claim 1, wherein said timing signals are time code numbers.

5. The real time interaction system as recited in claim 4, wherein said video frames are stored by time code number.

6. The real time interaction system as recited in claim 1, wherein said video content does not include embedded tags.

7. The real time interaction system as recited in claim 6, further including a system for reading linked video files which link predetermined pixel objects in said video frames with predetermined data objects.

8. The real time interaction system as recited in claim 7, wherein said linked video files are exported to said viewer interaction platform.

9. The real time interaction system as recited in claim 1, wherein said viewer interaction platform includes a local storage device for storing user selected video frames.

10. The real time interaction system as recited in claim 1, wherein said viewer interaction platform includes viewer frame interaction application that is configured to support playback of said video frames.

11. The real time interaction system as recited in claim 10, wherein said viewer frame interaction application is configured to support one or more local frame advance navigational buttons.

12. The real time interaction system as recited in claim 1, wherein said frame interaction application is configured to support, a frame advance dialog box which allows unselected frames on the server to be called on a time interval basis.

13. The real time interaction system as recited in claim 10, wherein said viewer frame interaction application is configured to support a drop down menu for selecting time intervals.

14. The real time interaction system as recited in claim 10, wherein said viewer interaction application is configured to support one or more server frame advance navigational buttons for viewing unselected frames in said server.

15. The real time interaction system as recited in claim 1, wherein said viewer interaction application supports a graphical user interface.
