## Abstract

According to one aspect of the present disclosure, a reception method in broadcast and broadband cooperation service, the reception method includes: receiving broadcast content transmitted through broadcast; receiving acquisition information through the broadcast, the acquisition information being information used to play back broadband content transmitted through broadband while the broadband content is synchronized with the received broadcast content, the acquisition information being information relating to acquisition of the broadband content; and acquiring the broadband content based on the received acquisition information. Therefore, the broadband content can properly be acquired in response to the reception of the broadcast content.

## Claims

### Claim 1

A reception method in a broadcast and broadband cooperation service, the reception method comprising:
receiving broadcast content transmitted through the broadcast;
receiving broadband content transmitted through the broadband;
receiving acquisition information and information indicating an attribute of the broadband content, the acquisition information and the information indicating the attribute of the broadband content being transmitted through the broadcast, the acquisition information being information on acquisition of the broadband content, and the acquisition information being information used to play back the broadband content in cooperation with the broadcast content;
and
acquiring the broadband content based on the acquisition information and the information indicating the attribute of the broadband content,
wherein the reception method further comprises:
receiving, through the broadcast, information indicating whether there is broadband content that cooperates with the broadcast content;
receiving, through the broadcast, first information including at least one item of information among the following information: information related to whether the broadband content is active or not, a viewing limit of the broadband content, and an indication of whether the broadband content at a given time is capable of being pre-acquired; and
obtaining the broadband content based on the acquisition information, the information indicating an attribute of the broadband content and the first information.

### Claim 2

A reception device used in a broadcast and broadband cooperation service, the reception device comprising:
a broadband receiver which, in operation, receives broadband content transmitted through the broadband; and
a broadcast receiver which, in operation, receives broadcast content transmitted through the broadcast, and receives acquisition information and information indicating an attribute of the broadband content, the acquisition information and the information indicating the attribute of the broadband content being transmitted through the broadcast, the acquisition information being information on acquisition of the broadband content, and the acquisition information being information that is used by the reception device to play back the broadband content in cooperation with the broadcast content,
wherein the broadband receiver acquires the broadband content based on the acquisition information and the information indicating the attribute of the broadband content,
the broadcast receiver receives, through the broadcast, information indicating whether there is broadband content that cooperates with the broadcast content,
the broadcast receiver further receives, through the broadcast, first information including at least one item of information among the following information: information related to whether the broadband content is active or not, a viewing limit of the broadband content, and an indication of whether the broadband content at a given time is capable of being pre-acquired, and
obtains the broadband content based on the acquisition information, the information indicating an attribute of the broadband content and the first information.

### Claim 3

A transmission method in a broadcast and broadband cooperation service, the transmission method comprising:
transmitting broadcast content through the broadcast;
transmitting broadband content through the broadband; and
transmitting acquisition information and information indicating an attribute of the broadband content through the broadcast, the acquisition information and the information indicating the attribute of the broadband content, and the acquisition information being information on acquisition of the broadband content,
wherein the acquisition information is information that is used by a reception device to play back the broadband content in cooperation with the broadcast content, and
the transmission method further comprises:
transmitting, through the broadcast, information indicating whether there is broadband content that cooperates with the broadcast content; and
transmitting, through the broadcast, first information including at least one item of information among the following information: information related to whether the broadband content is active or not, a viewing limit of the broadband content, and an indication of whether the broadband content at a given time is capable of being pre-acquired, wherein the broadband content is obtained based on the acquisition information, the information indicating an attribute of the broadband content and the first information.

### Claim 4

A transmission device used in a broadcast and broadband cooperation service, the transmission device comprising:
