A system for the winter transmission of media to an audio/visual output device

摘要

It is common to wish to play music (or more generally media files/tracks) from a media device 1, 2 such as a PC, portable audio/MP3 player or the like thorough an external device such as a home audio system (stereo system) 3, 4. This can be provided through a wireless link in which the system comprises a transceiver 3A for establishing a short range wireless connection (e.g. Bluetooth (RTM) link) with the media player 1, 2, and an output 3F which allows the device to be connected, to an Audio/Visual output device e.g. a speaker/screen 4. This application describes a media receiver 3 which can maintain two simultaneous short range wireless radio connections with two remote media players and whilst maintaining said connections and whilst receiving a first Audio/Visual signal/track from one of the media players, receive a second Audio/Visual signal/track from the other media player and route that second Audio/Visual signal/track to the Audio/Visual output device in preference to the first Audio/Visual signal/track i.e. the media receiver switches from routing/outputting the currently playing first media signal/track to the newly requested second media signal/track. The media player sending the first Audio/Visual signal/track may be instructed to pause or stop reading and/or transmitting the first signal/track. The audio receiver may receive Advance Audio Distribution Profile (A2DP) and/or Audio/Video Remote Control Profile (AVRCP)/ iPod Accessory Protocol (iAP) messages on which to base the decision on which signal/track to route to the output device. Embodiments comprising simultaneous connection to more than two media players [10, 20, 30, Figure 3] is also included.
