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 syncronization 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.

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.

Embodiments are provided for syncing multiple electronic devices for collective audio playback. According to certain aspects, a master device connects (218) to a slave device via a wireless connection. The master device calculates (224) a network latency via a series of network latency pings with the slave device and sends (225) the network latency to the slave device. Further, the master devices sends (232) a portion of an audio file as well as a timing instruction including a system time to the slave device. The master device initiates (234) playback of the portion of the audio file and the slave devices initiates (236) playback of the portion of the audio file according to the timing instruction and a calculated system clock offset value.
