Abstract
Techniques are described for concealing aspects of RC in the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In this way, by delivering information needed to play the RC very shortly before insertion is to occur, skipping strategies can be foiled.

A digital television system comprising:
- at least one receiver of digital television content with segment timeline signaling, the receiver being programmed with instructions to configure the receiver to:
- receive information pertaining to replacement content (RC) which does not include a start time for playing the RC, or which includes the start time in a form that only a broadcast application (app) provided by a digital television broadcaster can read;
- just prior to the start time, receive indication of the start time;
- and
- at the start time, play the RC.

A digital television system comprising:
- at least one source of broadcast digital television content;
- and
- at least one processor configured with instructions that are executable to:
- send, to at least one receiver, information in a Dynamic Adaptive Streaming over HyperText Transfer Protocol (HTTP) (DASH) Media Presentation Description (MPD) segment timeline time-based data structure, the information pertaining to replacement content (RC) which does not include a start time for playing the RC, or which includes the start time in a form that only a broadcast application (app) provided by a digital television broadcaster can read, such that the receiver can use the information to prepare insertion of the RC and play the RC by receiving, after preparing insertion of the RC, indication of the start time.
