Abstract

A user may simultaneously access sources of multimedia information via multiple wireless networks using a handheld multimedia gateway. A user interface may support the selection of information services that are each provided separate, but possibly overlapping, viewing spaces. Circuitry in the multimedia gateway manages the operation of the multiple wireless communication paths, and enables the display of visual information through two or more display devices. The user may customize the display, the size, and the location within a display of regions in which the information is presented.

Claims

1. A communication device for the exchange of multimedia information, the device comprising:

two or more wireless communication interfaces, wherein each interface communicates separate streams of multimedia information via independent radio frequency communication networks;

at least one visual display device for the display of text and images;

a controller adapted to establish and maintain communication via the radio frequency communication networks;

memory for storing data and program code accessible by the controller; and

wherein the program code supports consumption of each of the streams of multimedia information within associated user-defined regions of the at least one visual display.

2. The communication device according to claim 1 wherein the wireless communication interfaces comprise respective communication interfaces, each respective wireless communication interface being are compatible with a respective wireless wide area network protocol.

3. The communication device according to claim 2 wherein each respective wireless communication interface comprises a wireless communication interface compatible with at least one of

a code divisional multiple access (CDMA) cellular protocol,

a time division multiple access (TDMA) cellular protocol,

an Institute of Electrical and Electronics Engineers (IEEE) 802.16 protocol, and

a Digital Video Broadcast-Handhelds (DVB-H) protocol.

4. The communication device according to claim 3 wherein at least one respective wireless communication interface comprises a wireless communication interface compatible with a wireless local area network protocol.

5. The communication device according to claim 4 wherein the wireless local area network protocol comprises one of

an Institute of Electrical and Electronics Engineers (IEEE) 802.11 protocol,

an IEEE 802.15.3 a protocol, and

a Bluetooth compatible protocol.

6. The communication device according to claim 1 wherein each respective wireless communication interface of the two or more wireless communication interfaces is configurable to operate using a like number of respective incompatible wireless network protocols.

7. The communication device according to claim 1 further comprising:

a display controller operably coupled to the at least one visual display device, wherein the display controller operates in response to parameters defining user-defined display regions.

8. The communication device according to claim 1 wherein the at least one visual display device comprises a first visual display and a second visual display.

9. A method for a handheld communication device the method comprising:

at the handheld communication device, establishing a first communication session using a first radio frequency communication network;

associating a first user-definable display region of a display device of the handheld communication device with the first communication session;

establishing a second communication session using a second radio frequency communication network;

associating a second user-definable display region of a display device of the handheld communication device with the second communication session; and

communicating multimedia information using the first user-definable display region and the second user-definable display region, via the first and second communication networks, respectively.

10. The method of claim 9 wherein establishing a communication session comprises:

determining a bandwidth requirement for communication of multimedia information;

selecting a wireless network based upon the bandwidth requirement; and

communicating messaging via the selected wireless network to establish the communication session.

11. The method of claim 10 wherein the selection of the wireless network comprises:

i) identifying a wireless network that supports the determined bandwidth requirement and that is supported by the handheld communication device;

ii) determining remaining battery power of the handheld communication device;

iii) based on the determined remaining battery power, determining whether sufficient battery power remains to permit operation of the handheld communication device on the identified network;

iv) if so, employing the identified wireless network;

v) repeating steps (i) through (iv) if remaining battery power is not sufficient to permit operation of the handheld communication device on the identified network; and

(vi) providing a user notification if the determined remaining battery power is not sufficient to permit operation of the handheld communication device on any wireless network.

12. The method according to claim 9 wherein associating a respective user-definable display region with a communication session comprises:

allocating a region of the display device of the handheld communication device; and

displaying, within the allocated region of the display device, at least a portion of multimedia information communicated during the respective communication session.

13. The method according to claim 9 wherein communicating multimedia information comprises communicating at least one of

streaming video,

broadcast video,

digitized audio,

a digitized still image, and text.

14. The method of according to claim 9, wherein establishing a communication session using a radio frequency communication network comprises:

establishing a communication session with a remote network operating according to one of

a code divisional multiple access (CDMA) cellular protocol,

a time division multiple access (TDMA) cellular protocol,

an Institute of Electrical and Electronics Engineers (IEEE) 802.16 protocol, and

a Digital Video Broadcast-Handhelds (DVB-H) protocol.
