Abstract: The quality of a broadcast stream is varied responsive to changes in the utilization of forward link air interface resources. The network monitors utilization of forward link air interface resources and dynamically changes the forward link air interface resources dedicated to the broadcast stream responsive to changes in the utilization of forward link air interface resources. The quality of the broadcast stream is scaled to the allocated forward link resources. The broadcast stream may include a layered content and scaling can be achieved by varying the number of layers transmitted over the air interface. The network may notify mobile stations in advance when changes in the quality of the broadcast will take place. When the broadcast stream originates with a mobile station, the forward link air interface resources may be limited by the quality of the broadcast stream transmitted over a reverse link channel from the originating mobile station.

Abstract translation: 响应于前向链路空中接口资源的利用的变化，广播流的质量是变化的。 响应于前向链路空中接口资源的利用变化，网络监控前向链路空中接口资源的利用，动态改变专用于广播流的前向链路空中接口资源。 广播流的质量被缩放到所分配的前向链路资源。 广播流可以包括分层内容，并且可以通过改变通过空中接口传送的层的数量来实现缩放。 当广播质量发生变化时，网络可以预先通知移动台。 当广播流源自移动台时，前向链路空中接口资源可能受到来自发起移动台的反向链路信道发送的广播流的质量的限制。
