The present invention proposes a method of transmitting a broadcast signal. The method of transmitting a broadcast signal according to the present invention provides a system capable of supporting next-generation broadcast services in an environment supporting next-generation hybrid broadcast using terrestrial broadcast networks and the Internet. In addition, an efficient signaling method for covering terrestrial broadcast networks and the Internet in an environment supporting next-generation hybrid broadcast is proposed.

Disclosed is a display apparatus including: a receiver; a communicator; a display; and a processor configured to: obtain first media information and a service app from a broadcast signal received through the receiver, receive second media information corresponding to the first media information from a server through the communicator by executing the obtained service app, identify a different schedule section based on comparison in between content schedule of the first media information and content schedule of the second media information, and perform an operation convenient for a user to use the broadcast program, based on the identified schedule section.

The present technology relates to a data processing apparatus and a data processing method that enable correct clock synchronization by use of clock information. The data processing apparatus receives a digital broadcast signal so as to process content included in the digital broadcast signal and clock information also included therein for use in presentation synchronization on the content and sends via a transmission path the processed content and clock information to another data processing apparatus that presents the received content. On the other hand, the another data processing apparatus receives via the transmission path the content and clock information sent from the data processing apparatus so as to process presentation synchronization on the received content on the basis of the received clock information. The present technology is applicable to data processing apparatuses configured to process content, for example.

The present technology relates to a reception apparatus and a data processing method that ensure reliable reproduction of content.

The reception apparatus receives content, and controls reproduction of the content on the basis of time correspondence information associating first time information provided from a transmission side of the content with second time information generated on a reception side of the content by a time axis according to the first time information corresponding to the second time information. The present technology can be applied to a television receiver compatible with ATSC 3.0, for example.
