    • 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.
    • 提供了一种用于在无线环境中动态调整多媒体数据分辨率的方法和计算机可读介质。 该方法包括:确定移动台的接入简档; 监测无线系统中的传输条件; 基于所述传输条件以最高分辨率向所述移动台发送所述多媒体数据和控制信令,其中所述控制信令基于所述移动台的接入简档来确定所述移动台可访问的所述多媒体数据的量; 并且如果传输条件变得不可接受以便以最高分辨率发送多媒体数据,则降低正在发送到移动台的多媒体数据的分辨率。 如果传输条件对于以更高分辨率发送多媒体数据是可接受的,则传输到移动台的多媒体数据的分辨率基于传输条件增加到最高可能的分辨率。
