Abstract

A host device is disclosed. The host device includes a processor and a control mechanism. The processor operates to receive primary and associated data, decode and separate the associated data from the primary data, and cause the associated data to be rendered on a separate hand held device. The processor also operates the control mechanism to control a separate display apparatus to separately receive and render the primary data.

Claims

1. A system, comprising:

a primary data stream generator to generate a primary data stream comprising primary data, wherein the primary data comprises broadcast programming;

an associated data stream generator to generate an associated data stream comprising associated data, wherein the associated data comprises information relevant to the primary data;

a data synchronizer for synchronizing the primary data stream and the associated data stream to generate a script based on a predetermined criteria, wherein the script specifies the points in time when the primary data stream and the associated data stream are delivered with respect to each other;

a sequencer to combine the primary data stream with the associated data stream as specified in the script to sequentially transmit the associated data stream with respect to the primary data stream;

an encoder to encode the primary data stream and the associated data stream; and

a transmitter for transmitting the primary data stream to a primary data device and the associated data stream to a remotely-located associated data device.

2. The system of claim 1, wherein the script further specifies the points in time when the primary data and the associated data are displayed with respect to each other.

3. The system of claim 1, further comprising:

a receiver for receiving the primary data stream and the associated data stream;

a decoder to decode the primary data stream and the associated data stream; and

a device to render and display the primary data and the associated data.

4. The system of claim 1, wherein the script is delivered to a user before delivering the primary data stream and the associated data stream to the user.

5. The system of claim 1, wherein the associated data stream is interactively accessible.

6. An apparatus, comprising:

a primary data stream generator to generate a primary data stream comprising primary data, wherein the primary data comprises broadcast programming;

an associated data stream generator to generate an associated data stream comprising associated data, wherein the associated data comprises information relevant to the primary data;

a data synchronizer for synchronizing the primary data stream and the associated data stream to generate a script based on a predetermined criteria, wherein the script specifies the points in time when the primary data stream and the associated data stream are delivered with respect to each other; and

a sequencer to combine the primary data stream with the associated data stream as specified in the script to sequentially transmit the associated data stream with respect to the primary data stream.

7. The apparatus of claim 6, wherein the script further specifies the points in time when the primary data and the associated data are displayed with respect to each other.

8. The apparatus of claim 6, wherein the script is delivered to a user before delivering the primary data stream and the associated data stream to the user.

9. The apparatus of claim 6, wherein the associated data stream is interactively accessible.

10. The apparatus of claim 6, further comprising:

an encoder to encode the primary data stream and the associated data stream;

a decoder to decode the primary data stream and the associated data stream; and

a transmitter for transmitting the primary data stream to a primary data device and the associated data stream to a remotely-located associated data device.

11. The apparatus of claim 6, further comprising:

a receiver for receiving the primary data stream and the associated data stream; and

a device to render and display the primary data and the associated data.

12. A method, comprising:

generating a primary data stream comprising primary data, wherein the primary data comprises broadcast programming;

generating an associated data stream comprising associated data, wherein the associated data comprises information relevant to the primary data;

synchronizing the primary data stream and the associated data stream to generate a script based on a predetermined criteria, wherein the script specifies the points in time when the primary data stream and the associated data stream are delivered with respect to each other; and

combining the primary data stream with the associated data stream as specified in the script to sequentially transmit the associated data stream with respect to the primary data stream.

13. The method of claim 12, wherein the script further specifies the points in time when the primary data and the associated data are displayed with respect to each other.

14. The method of claim 12, further comprising delivering the script to a user before delivering the primary data stream and the associated data stream to the user.

15. The method of claim 12, wherein the associated data stream is interactively accessible.

16. The method of claim 12, further comprising:

encoding the primary data stream and the associated data stream;

decoding the primary data stream and the associated data stream; and

transmitting the primary data stream to a primary data device and the associated data stream to a remotely-located associated data device.

17. The method of claim 12, further comprising:

receiving the primary data stream and the associated data stream; and

rendering and displaying the primary data and the associated data.
