SINK DEVICE, SOURCE DEVICE AND WIRELESS TRANSMISSION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2011/122456

Kind Code:

A1

Abstract:

Disclosed is a wireless transmission system provided with: a sink device which, when AV data transmitted by means of multicast wireless transmission from a source device is reproduced, performs reproduction control in accordance with the wireless connection state of another sink device that reproduces the AV data from the same source device; and the source device which is capable of determining the wireless connection state and the reproduction control state of the sink device. When the AV data obtained by means of multicast wireless transmission from the source device (1) is reproduced, the sink device (2a) acquires state information indicating the wireless connection state of the other sink device and adjusts reproduction control for the AV data of the actual sink device (2a) in accordance with this state information. The source device (1) acquires information on the wireless connection state and the reproduction control state of each sink device and stops or restarts transmission of the AV data on the basis of this information.
