TRANSMISSION METHOD, RECEPTION METHOD, TRANSMISSION DEVICE, AND RECEPTION DEVICE
First Claim
1. A transmission method for enabling transmission of content using a broadcast wave and a communication channel, the transmission method comprising:
- transmitting auxiliary information using at least the broadcast wave, the auxiliary information being information for synchronizing content transmission using the broadcast wave and content transmission using the communication channel when the content is transmitted using the broadcast wave and the communication channel, and the auxiliary information causing a reception side to perform the synchronization when the reception side receives the auxiliary information.

Abstract
According to one aspect of the present disclosure, a transmission method for enabling transmission of content using a broadcast wave and a communication channel includes: transmitting auxiliary information using at least the broadcast wave, the auxiliary information being information for synchronizing content transmission using the broadcast wave and content transmission using the communication channel when the content is transmitted using the broadcast wave and the communication channel, and the auxiliary information causing a reception side to perform the synchronization when the reception side receives the auxiliary information. Therefore, even if timing of starting reception of the content through the communication is delayed, the reception side can play back the content by a combination of the broadcasting and the communication.
