Abstract
Mechanisms are provided for efficient transition between broadcast media reception and multicast/unicast media reception. Broadcast media quality is dynamically analyzed to determine when transition is appropriate. Broadcast services are mapped to multicast/unicast delivered services. Transition occurs smoothly by acquiring both broadcast and multicast/unicast media during transition and analyzing timing data to allow for media stream alignment and switchover.
Claims9
A method, comprising:
- receiving a broadcast media stream from a terrestrial transmitter using an Advanced Television Systems Committee (ATSC) antenna on a mobile device;
- determining that the broadcast media stream no longer meets a quality threshold;
- receiving a multicast/unicast media stream on the mobile device over a wireless network, the wireless network delivering Internet Protocol (IP) data;
- monitoring timing information for the broadcast media stream and the multicast/unicast media stream;
- transitioning to the multicast/unicast media stream after aligning the broadcast media stream and the multicast/unicast media stream.
