Abstract

An interactive video menu system provides an economical method for the storage, transmission, and reception of data necessary for interactive video sessions, which allows high-resolution images to be broadcast to end users along with all the control information necessary to display and navigate through these images. A simple interpretive script is run on the end user'"'"'s device which traps the broadcast information and allows rapid response time and control of the interactive session without requiring expensive high-bandwidth facilities. Buffer equalized coding is used so that still, picture-in-a-still; and moving video images can be compressed at rates below those typically used with the MPEG-2 standard and continuously transmitted as video backgrounds in a seamless loop saving bandwidth without degradation in video quality. Data that instructs the end-user device how to display the video backgrounds and what foreground text to overlay on the video backgrounds is broadcast simultaneously in the bit stream This creates the appearance of a dedicated connection to the server while minimizing bandwidth and equipment cost and complexity.

Claims

1. An interactive video menu system which can display a video menu to a user, comprising:

a program encoder for compressing post-produced video material and generating compressed background video images;

a script station which outputs

(a) foreground text data based on the post-produced video material, and

(b) instructions for

(i) displaying the foreground text data to overlay the background video images, and

(ii) responding to a command from the user based on the video menu, wherein

the foreground text data and the instructions form a script;

a processing engine coupled to the program encoder and to the script station which

(i) processes the compressed background video images to generate a clip, and

(ii) assembles the script into a number of script packets which are associated with the clip;

a server coupled to the processing engine which

(i) stores the clip, and

(ii) continuously broadcasts the clip simultaneously with the associated script packets into a broadband transmission medium; and

an end-user device coupled to the broadband transmission medium to receive the clip and associated script packets, which (i) using the clip, displays the background video images, and (ii) using the script packets, overlays foreground text on the displayed background video images.

2. A system as defined in claim 1, wherein:

a single script packet is associated with each clip.

3. A system as defined in claim 1, wherein:

a plurality of script packets are associated with each clip.

4. A system as defined in claim 1, wherein:

the clip is sent in a first digital channel, and

the script is sent in a second digital channel.

5. A system as defined in claim 1, wherein:

the clip is broadcast at a bit rate of less than 2.5 Mbps.

6. A system as defined in claim 1, wherein:

the processing engine uses buffer equalized coding in processing the compressed background video images.

7. A system as defined in claim 1, wherein:

the server stores a number of clips.

8. A system as defined in claim 1, wherein the end-user device compromises:

a display screen and a remote control.

9. A system as defined in claim 1, further comprising:

one or more additional end-user devices coupled to the broadband transmission medium, wherein

each additional end-user device receives the clip and associated script packets.

10. A system for displaying a menu in an interactive video system, comprising:

(A) means for compressing post-produced video material to create compressed background video images;

(B) means for creating (i) foreground text data based on the post-produced video material and (ii) instructions for overlaying foreground text on the background video images and for responding to a command from a user, wherein the foreground text data and the instructions form a script;

(C) means for processing the compressed background video images using buffer equalized coding to generate a clip;

(D) means for assembling the script into a number of script packets which are associated with the clip;

(E) means for continuously broadcasting a number of buffer-equalized clips and associated script packets into a broadband transmission medium; and

(F) means, coupled to the broadband transmission medium, for displaying the background video images and foreground text instantiated over the displayed background video images.

11. A system as defined in claim 10, wherein:

the number of clips and associated script packets are broadcast simultaneously.

12. A system as defined in claim 10, wherein:

the means for displaying uses the clips to display the background video images.

13. A system as defined in claim 10, wherein:

the means for displaying uses the script packets to instantiate the foreground text over the displayed background video images.

14. A system as defined in claim 10, wherein the means for displaying includes:

plurality of end-user devices.

15. A process for creating a video image with text that includes a menu page for use in an interactive video menu system, comprising the following steps:

(A) broadcasting into a broadband transmission medium a bit stream of buffer-equalized clips and script packets;

(B) based on the clips, displaying background video images on an end-user device coupled to the broadband transmission medium; and

(C) based on the script packets, instantiating foreground text over the displayed background video images to present the video image with text that includes a menu page.

16. A process as defined in claim 15, wherein:

the buffer-equalized clips are compressed according to the MPEG-2 standard.

17. A process as defined in claim 15 wherein:

the clips indicate the background video images to be displayed, and

the script packets indicate the foreground text and instructions for instantiating the foreground text over the background video images and for responding to user commands.

18. A process as defined in claim 15, wherein:

one or more script packets are associated with each of the clips.

19. A process as defined in claim 15, wherein:

the clips and script packets are broadcast simultaneously in step (A).

20. A process as defined in claim 15, wherein:

the end-user device is part of a network of end-user devices, wherein each end-user device of the network receives the bit stream of clips and script packets.
