Abstract
A service quality metric, that measures the quality of a multicast broadcast that is being received by a mobile device, may be determined. In one implementation, a method may include receiving a radio signal corresponding to a multicast broadcast of content that was encoded using a forward error correction (FEC) technique in which the content is segmented and encoded as a plurality of blocks; and reassembling the content corresponding to the received radio signal. The method may further include determining an FEC failure rate based on a relative occurrence of the successfully reassembled blocks to the unsuccessfully reassembled blocks; determining a service quality metric based on the FEC failure rate; and providing a visual indication of the service quality metric.
