Method and computer-readable medium for dynamically adjusting a multimedia data resolution in a wireless environment
First Claim
1. A method for transmitting multimedia data over a plurality of channels to a mobile station in a wireless system, the method comprising the acts of:
- receiving, from the mobile station, a request for access to the multimedia data;
determining an access profile of the mobile station, wherein the access profile indicates an amount of the multimedia data that is accessible to the mobile station;
identifying, based on the access profile, which of the plurality of channels are accessible to the mobile station; and
transmitting the multimedia data over the plurality of channels accessible to the mobile station,wherein the multimedia data is partitioned into a basic channel and one or more enhanced channels, and the access profile determines whether the basic channel is accessible to the mobile station and determines which of the enhanced channels are accessible to the mobile station.

Abstract
A method and computer-readable medium for dynamically adjusting a multimedia data resolution in a wireless environment is provided. The method includes: determining the access profile of the mobile station; monitoring transmission conditions in the wireless system; transmitting the multimedia data and control signaling to the mobile station with a highest resolution based upon the transmission conditions, wherein the control signaling determines an amount of the multimedia data accessible to the mobile station based upon the access profile of the mobile station; and decreasing a resolution of the multimedia data being transmitted to the mobile station, if the transmission conditions become unacceptable for transmitting the multimedia data at the highest resolution. If the transmission conditions become acceptable for transmitting the multimedia data at a higher resolution, the resolution of the multimedia data being transmitted to the mobile station is increased to the highest possible resolution based upon the transmission conditions.

10. A method for transmitting multimedia data to a plurality of mobile stations in a wireless system, the method comprising the acts of:
-
determining an access profile of each of the mobile stations, wherein the access profiles indicate an amount of the multimedia data that is accessible to each of the mobile stations; monitoring transmission conditions in the wireless system; transmitting the multimedia data and control data to each of the mobile stations with a highest resolution based upon the transmission conditions, wherein the control data determines an amount of the multimedia data accessible to each of the mobile stations based upon the access profile of each of the mobile stations; and decreasing a resolution of the multimedia data being transmitted to the mobile stations, when the transmission conditions become unacceptable for transmitting the multimedia data at the highest resolution, wherein the multimedia data is partitioned into a basic channel and one or more enhanced channels, and the access profile of each of the mobile stations determines whether the basic channel is accessible to each of the mobile stations and determines which of the enhanced channels are accessible to each of the mobile stations. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method for establishing a multimedia channel association between a base station and a mobile station in a wireless environment, the method comprising the acts of:
-
receiving a request for multimedia data from the mobile station; determining an access profile of the mobile station, wherein the access profile indicates an amount of the multimedia data that is accessible to the mobile station; establishing the multimedia channel association based upon the access profile; informing the mobile station of the multimedia channel association; and increasing the number of the plurality of channels transmitted to the mobile station, when the transmission conditions become acceptable for transmitting more of the plurality of channels, wherein the multimedia data is partitioned into a basic channel and one or more enhanced channels, and the access profile determines whether the basic channel is accessible to the mobile station and determines which of the enhanced channels are accessible to the mobile station. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
