Abstract

Methods and systems for distributed infrastructure for streaming data via multiple access points. Aspects of one method may include apportioning multimedia information among a plurality of transmitting devices based on feedback channel information received from a destination receiving device by, for example, a transmission controller device The transmitting devices may transmit the multimedia information to the destination receiving device A transmitting device that may not be apportioned multimedia information may transmit a probing signal The destination receiving device may generate feedback channel information for a transmitting device, for example, based on the multimedia information or the probing signal received from the respective transmitting device. The apportioning of the multimedia information may be dynamically adjusted based on updated feedback channel information received from the destination receiving device

Claims

1. A method for communicating information, the method comprising.

apportioning multimedia information among a plurality of transmitting devices for transmission by said plurality of transmitting devices to a destination receiving device, based on channel information received from said destination receiving device.

2. The method according to claim 1, comprising dynamically adjusting said apportioning of said multimedia information among said plurality of transmitting devices based on updated channel information received from said destination receiving device.

3. The method according to claim 1, wherein said multimedia information comprises at least one of the following:

video information, audio information, and data.

4. The method according to claim 1, comprising controlling said apportioning of said multimedia information via a transmission controller device.

5. The method according to claim 4, wherein said transmission controller device is integrated into one of said plurality of transmitting devices.

6. The method according to claim 1, comprising determining a priority for at least a portion of said multimedia information based on said received channel information.

7. The method according to claim 6, comprising applying at least one of a plurality of forward error correction codes to said at least a portion of said multimedia information based on said priority.

8. The method according to claim 6, comprising applying by each of said transmitting devices one of a plurality of RF modulation schemes to said apportioned multimedia information based on said priority.

9. The method according to claim 1, comprising transmitting by each of said plurality of transmitting devices on one of a plurality of different RF channels.

10. The method according to claim 1, comprising transmitting a probing signal by at least one of said plurality of transmitting devices that is not apportioned to transmit said multimedia information, wherein said probing signal is used by said destination receiving device to generate said channel information.

11. A machine-readable storage having stored thereon, a computer program having at least one code section for handling data in a communication system, the at least one code section being executable by a machine for causing the machine to perform steps comprising:

apportioning multimedia information among a plurality of transmitting devices for transmission by said plurality of transmitting devices to a destination receiving device, based on channel information received from said destination receiving device.
