Abstract
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. To improve robustness for datacast files to limited memory platforms, each file is divided into partitions and then the packets in a partition are arranged out of order (OOO), with the partitions then being sent in order with their respective packets OOO.
Claims20
A method, comprising:
- dividing at least one file into plural partitions;
- within each partition, arranging packets of the partition out of order (OOO), the packets of the partition being arranged OOO relative to the packets being in order as defined by the at least one file;
- and
- sending the partitions in order with their respective packets OOO to at least one receiver, the partitions being in order as defined by the at least one file.
1 more element
A digital television apparatus, comprising:
- at least one receiver configured to receive digital television signals from a digital television transmitter system, the receiver comprising at least one processor programmed with instructions for:
- receiving, into non-persistent memory, at least some partitions of plural partitions of at least one file, each partition of the at least some partitions comprising packets out of order (OOO), the packets being OOO relative to the packets being in correct order as defined by the at least one file;
- ordering the packets from OOO into the correct order;
- sending at least one partition in non-persistent memory to persistent memory;
- and
- receiving into the non-persistent memory additional partitions.
