Abstract

A hand held device for use to separately render associated data is disclosed. The hand held device includes a display element, a processor, and a communication interface. The communication interface operates to receive rendering commands of the associated data from a host device, which received the associated data in conjunction with primary data, and subsequently separated the associated data from the primary data. The processor causes the associated data to be rendered on the display element. The hand held device further includes an enclosure for housing the display element etc., which has physical dimensions that are suitable for hand held usage while viewing the primary data, which are separately rendered.

Claims

1. An apparatus comprising:

(a) a display element;

(b) a processor coupled to the display element to cause associated data to be rendered on the display element responsive to received rendering commands of the associated data;

(c) a communication interface coupled to the processor to receive the rendering commands of the associated data from a computer, the computer to receive the associated data in conjunction with primary data, and subsequently decode and separate the associated data from the primary data, said computer further to cause the primary data to be rendered on a different display apparatus; and

(d) an enclosure to house the display element, the processors and the communication interface, the enclosure having physical dimensions on the order of a hand held device, suitable for hand held usage of the apparatus while viewing the primary data rendered on the different display apparatus.

2. The apparatus as set forth in claim 1, wherein the display element comprises a flat panel display.

3. The apparatus as set forth in claim 1, wherein the communication interface comprises a wireless communication interface.

4. The apparatus as set forth in claim 1, wherein

the apparatus further comprises an input mechanism to facilitate associated data request inputs;

the processor is further coupled to the input mechanism, the processor to forward the associated data request inputs to the communication interface; and

the communication interface is further to forward the associated data request inputs to the computer.

5. The apparatus as set forth in claim 4, wherein the input mechanism comprises a stylus.

6. The apparatus as set forth in claim 4, wherein communication interface comprises a wireless transmitter/receiver.

7. The apparatus as set forth in claim 1, wherein the computer comprises a television and the different display apparatus is a CRT element of the television.

8. The apparatus as set forth in claim 1, wherein the host apparatus comprises a television and the different display apparatus comprises a CRT element of the television.

9. A system comprising:

(a) a computer to receive primary and associated data, decode and separate the associated data from the primary data, and cause the primary and associated data to be separately rendered; and

(b) a hand held device communicatively coupled to the computer to render the associated data, the hand held device having external physical dimensions that are suitable for hand held usage while viewing the separately rendered primary data.

10. The system as set forth in claim 9, wherein the hand held device comprises:

(b.1) a communication interface to receive rendering commands of the associated data from the computer;

(b.2) a processor coupled to the communication interface and an associated display element, the processor to cause the associated data to be rendered on the associated display element;

(b.3) the associated display element; and

(b.4) an enclosure to house the associated display element, the processor, and the communication interface, the enclosure having the external physical dimensions.

11. The system as set forth in claim 10, wherein the associated display element comprises a flat panel display.

12. The system as set forth in claim 10, wherein the communication interface comprises a wireless communication interface.

13. The system as set forth in claim 10, wherein

the hand held device further comprises an input mechanism to facilitate associated data request inputs;

the processor is further coupled to the input mechanism, the processor to forward the associated data request inputs to the communication interface; and

the communication interface is further to forward the associated data request inputs to the computer.

14. The system as set forth in claim 13, wherein the input mechanism comprises a stylus.

15. The system as set forth in claim 13, wherein the communication interface comprises a wireless transmitter/receiver.

16. The system as set forth in claim 9, wherein the system further comprises a primary display device coupled to the computer to render the primary data.

17. The system as set forth in claim 9, wherein the computer comprises a television, and the primary data are rendered on a CRT element of the television.

18. An apparatus comprising:

a display element;

a processor coupled to the display element to cause associated data to be rendered on the display element responsive to received rendering commands of the associated data;

a communication interface coupled to the processor to receive the rendering commands of the associated data from a host apparatus, the host apparatus to receive the associated data in conjunction with primary data, and subsequently decode and separate the associated data from the primary data, the host apparatus further to cause the primary data to be rendered on a different display apparatus;

an input mechanism coupled to the processor to facilitate associated data request inputs, the processor to forward the associated data request inputs to the communication interface, and the communication interface to forward the associated data request inputs to the host apparatus; and

an enclosure to house the display element, the processor, the communication interface, and the input mechanism, the enclosure having physical dimensions on the order of a hand held device, suitable for hand held usage of the apparatus while viewing the primary data rendered on the different display apparatus.
