HYBRID UNICAST AND MULTICAST DATA DELIVERY.

摘要

Hybrid unicast and multicast data delivery involves delivering data to client devices partially using a unicast communication and partially using a multicast communication. For example, higher-relevancy television metadata may be extracted from television metadata. A server transmits the higher-relevancy television metadata to a client via a unicast communication burst. The client can otherwise receive the television metadata from the server via a multicast communication stream.
