## Abstract

A transmitting method for transmitting contents using a broadcast wave and a communication path comprises: including content information in application control information when transmitting the contents using both the broadcast wave and the communication path, the content information being information for synchronizing a content transmitted by using the broadcast wave with a content transmitted by using the communication path at a reception side that receives the contents and being related to the content transmitted by using the communication path; and transmitting the application control information by using at least the broadcast wave in the broadcast wave and the communication path. As a result, a contents transmitting method is provided for enabling a quick access to contents through communication when the contents are reproduced by a combination of broadcast and communication on the receiving side.

## Claims

### Claim 1

A receiving method comprising:
receiving a first control data and a first media data, the first control data including first time information indicating a presentation start time of the first media data specified in a first timeline, the first control data including first location information, the first location information being used to obtain a second control data, the second control data including a second location information, the second location information being used to obtain a second media data;
receiving the second control data and the second media data, the second control data including second time information indicating a presentation start time of the second media data specified in a second timeline;
decoding and representing the first media data based on the first control data; and
decoding and representing the second media data based on the first control data, wherein
an absence of an offset value in the first control data indicates the first timeline and the second timeline are identical, the offset value indicating a difference between the first timeline and the second timeline.

### Claim 2

A receiving apparatus comprising:
a processor; and a memory, wherein
the processor, in operation, performs:
receiving a first control data and a first media data, the first control data including first time information indicating a presentation start time of the first media data specified in a first timeline, the first control data including first location information, the first location information being used to obtain a second control data, the second control data including a second location information, the second location information being used to obtain a second media data;
receiving the second control data and the second media data, the second control data including second time information indicating a presentation start time of the second media data specified in a second timeline;
decoding and representing the first media data based on the first control data; and
decoding and representing the second media data based on the first control data, wherein
an absence of an offset value in the first control data indicates the first timeline and the second timeline are identical, the offset value indicating a difference between the first timeline and the second timeline.
