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. An ATSC 3.0 receiver backs off the live point of a broadcast by a short delay period such that channel change may be rendered perceptibly faster by pre-fetching segments identified in a SegmentTemplate MPD from broadband before the broadcast channel is fully tuned to.
