Abstract

Systems, methods, and devices enable a receiver device to determine completeness of low level signaling (LLS) tables received via broadcast transmissions. In various embodiments, broadcast service signaling may include generating a directory table identifying one or more LLS tables to be broadcast and sending the directory table in a broadcast stream of the one or more LLS tables. In various embodiments, broadcast service signaling may include calculating a cyclic redundancy check (CRC) code for, generating a hash value for, and / or applying a digital signature to one or more LLS tables in a broadcast stream.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application 62 / 664,902, filed April 30, 2018, entitled "Method for Validating LLS Table Receipt," the entire contents of which are incorporated herein by reference. Background technique [0003] Among current broadcasting systems, such as a broadcasting system operating according to Advanced Television Systems Committee (ATSC) standards (for example, ATSC 2.0, ATSC 3.0, etc.), a digital video broadcasting (Digital Video Broadcasting, DVB) standard operating In a broadcast system, a broadcast system operating according to the 3rd Generation Partnership Project (3GPP) standard, etc., signaling information required for a receiver device to acquire a broadcast service is carried in low-level signaling received via broadcast transmission ( low levelsignaling, LLS) table. In such current systems, the receiver device must wait for a full repetition period to ensure th...
