A METHOD AND AN APPARATUS FOR PROCESSING A BROADCAST SIGNAL INCLUDING AN INTERACTIVE BROADCAST SERVICE |
摘要 |
A method of processing a broadcast signal including an interactive broadcast service at a transmitter is disclosed. The method comprises generating an parameter table containing metadata about applications and interactive broadcast events targeted to the applications, dividing the parameter table into a plurality of parameter blocks, inserting each of the parameter blocks into each of a plurality of parameter table sections, generating a trigger which is a signaling element to identify signaling and establish timing of playout of the interactive broadcast events, inserting the trigger into a closed caption channel of the broadcast signal, transmitting the broadcast signal including the closed caption channel and a specific channel carrying the plurality of parameter table sections, wherein the trigger includes location information specifying a location of the parameter table in the broadcast signal. |

1. A method of processing a broadcast service at a transmitter, the method comprising:
generating a parameter element containing metadata about applications of a segment and events targeted to the applications; generating an activation message element used for delivering activation triggers which set activation times for events; generating a message including the parameter element as a first part and the activation message element as a second part; transmitting the broadcast service via a broadcast channel; and transmitting the generated message via an internet network, wherein the activation message element includes a target application attribute identifying a target application for an activation command. |
