Abstract
Data transmitted over different channels may be updated by receiving one or more input data streams containing data for one or more digital data services, wherein the data is in the form of a plurality of packets, wherein each packet includes information identifying a channel and a number of related downstream packets; determining from the plurality of packets a time that an update packet containing data for one of the digital data services will be transmitted as part of the signal; and generating a schedule packet containing the time that the update packet will be transmitted as part of a signal.
Claims14
A method for generating an update schedule for data transmitted with a signal, comprising:
- a) receiving one or more input data streams containing data for one or more data services, wherein the data is in the form of a plurality of packets, wherein each packet includes information identifying a channel and a number of related downstream packets;
- b) determining from the plurality of packets a time that an update packet containing data for one of the data services will be transmitted as part of a signal;
- c) generating a schedule packet containing the time that the update packet will be transmitted as part of the signal;
- and
- d) transmitting the schedule packet as part of the signal.
An apparatus for generating an update schedule for data transmitted with a signal, comprising:
- a processor;
- a memory;
- a set of processor-executable instructions embodied in the memory, the instructions being configured to implement a method, the method comprising:
- a) receiving one or more input data streams containing data for one or more data services, wherein the data is in the form of a plurality of packets, wherein each packet includes information identifying a channel and a number of related downstream packets;
- b) determining from the plurality of packets a time that an update packet containing data for one of the data services will be broadcast as part of a signal;
- c) generating a schedule packet containing the time that the update packet will be transmitted as part of the signal;
- and
- d) transmitting the schedule packet as part of the signal.
A non-transitory computer-readable medium having instructions embodied therein for implementing a method for generating an update schedule for data transmitted with a signal, wherein the method comprises:
- a) receiving one or more input data streams containing data for one or more data services, wherein the data is in the form of a plurality of packets, wherein each packet includes information identifying a channel and a number of related downstream packets;
- b) determining from the plurality of packets a time that an update packet containing data for one of the data services will be transmitted as part of the signal;
- c) generating a schedule packet containing the time that the update packet will be transmitted as part of the signal;
- and
- d) transmitting the schedule packet as part of the signal.
