Apparatus for transmitting broadcast signal, apparatus for receiving broadcast signal, method for transmitting broadcast signal and method for receiving broadcast signal
First Claim
1. A method for processing transmission of a broadcast signal, performed by an apparatus for processing transmission of the broadcast signal, the method comprising:
- generating first broadcast data for a first broadcast service using a Moving Picture Experts Group (MPEG) media transport (MMT) protocol;
generating second broadcast data for a second broadcast service using a real-time object delivery over unidirectional transport (ROUTE) protocol;
generating first service level signaling information comprising information for describing attribute of the first broadcast service;
generating second service level signaling information comprising information for describing attribute of the second broadcast service;
generating low level signaling information comprising information for listing the first broadcast service and the second broadcast service;
generating one or more link layer packets comprising the first broadcast data, the second broadcast data, the first service level signaling information, the second service level signaling information, and the low level signaling information;
generating a broadcast signal comprising the one or more link layer packets; and
transmitting the broadcast signal,wherein the low level signaling information comprises service level signaling protocol information for identifying whether the first service level signaling information or the second service level signaling information is processed and transmitted according to the MMT protocol or the ROUTE protocol, and service level signaling position information comprising information required to acquire the first service level signaling information and the second service level signaling information.
