摘要:
The present principles provide a method for a personalized mobile broadcast service operator (Service provider) to send content in the form of files with different compression formats in a variable bandwidth channel to one or more users who have access to the same service. Operators providing mobile broadcasts have the option of using residual bandwidth to provide these services. In such services, depending on the amount of bandwidth available for a mobile broadcast, a scheduler can choose to broadcast file content with higher compressed parameters thereby reducing the network footprint of the content file during lower bandwidth situations. A lower compressed format of the same content could then be potentially scheduled to broadcast at a later time when more bandwidth becomes available eventually replacing the highly compressed copy which was received earlier on the client.
摘要(中):
本原理提供了一种个性化移动广播服务运营商(服务提供商)以可变带宽信道中的不同压缩格式的文件的形式将内容发送给具有访问相同服务的一个或多个用户的方法。 提供移动广播的运营商可以选择使用剩余带宽来提供这些服务。 在这样的服务中,根据可用于移动广播的带宽量,调度器可以选择以更高的压缩参数来广播文件内容,从而在较低带宽情况下减少内容文件的网络覆盖。 然后可以将相同内容的较低压缩格式潜在地安排在稍后的时间广播,当更多带宽变得可用时,最终替换先前在客户机上接收到的高度压缩的副本。
