REDUCING LATENCY DURING SERVICE CHANGE AND IMPROVING ROBUSTNESS IN ADVANCED TELEVISION SYSTEMS COMMITTEE (ATSC) 3.0 SYSTEM

摘要

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. Signaling indicates where the first few segments of a changed-to broadcast service can be obtained on the broadband network. Segments not including the live edge segments are downloaded and played immediately to reduce perceived latency in the service change until the broadcast segments arrive for presentation.
