Method for efficient feedback of receiving channel conditions in adaptive video multicast and broadcast systems
Abstract:
A method and apparatus for providing channel condition feedback in a multicast network are described including estimating a indication of channel condition, determining a receiver class based on the estimated indication of channel condition, calculating a delay, delaying transmission of the estimated indication of channel condition for the calculated delay, receiving a report from another receiver in the determined receiver class, the report including an indication of channel condition and canceling the delay if the received indication of channel condition is one of greater than and equal to the estimated indication of channel condition. The method and apparatus further include transmitting a single report for the calculated receiver class to a server including a worst indication of channel condition for the determined receiver class.
