Description

This invention relates to an information processing device, an information processing method, a program, and a wireless transmission system. Wireless transmission technology is known in which multimedia signals such as video and audio are transmitted wirelessly from source devices such as mobile devices and received wirelessly by sink devices such as monitors. In wireless transmission technology, connection configurations between source and sink devices are not limited to one-to-one; one-to-many and many-to-one technologies are also known. In conventional technologies, in one-to-many connection configurations, it is necessary to perform the necessary connection processing for each device individually, such as during the initial connection. To address this problem, a technology has been proposed that manages multiple sink devices as groups using IDs (identifiers), thereby centrally managing the control of each group (see, for example, Patent Document 1).

The connection application of the following embodiment may be applied to medical devices, network home appliances, game consoles, etc., to realize a wireless transmission system with multiple output devices (including projectors, IWBs (Interactive White Boards: whiteboards with electronic blackboard functions that enable mutual communication), digital signage, etc.). In the following embodiments, an information processing device that processes and transmits multimedia signals, including video or audio data, wirelessly may be referred to as a "source device." Furthermore, an output device with wireless communication capabilities that receives multimedia signals wirelessly and outputs them as video or audio may be referred to as a "sink device." Devices that possess both information processing functions for processing and transmitting multimedia signals, and wireless communication output functions for receiving multimedia signals and outputting video or audio, such as personal computers (PCs) and smartphones, can function as both source and sink devices.
