[0013] along with the vehicle sustainable development of adopting or use multimedia equipment, thus by provide flexibly and more cheaply mechanism multimedia equipment is coupled to together MOST

(as, mobile multimedia link (MML)) advanced current techniques based on multimedia bus schemes with other.

[0014] day by day satisfied being to use with welcome entertainment features of consumer is connected portable audio device, as adopt the music player of MPEG1 audio compression the 3rd layer (MPEG1 layer 3), as the mechanism of the iPod or the similar player of Apple, playing back music on the boombox of its vehicle.Thereby consumer wants produces high-quality sound and use the solution of minimum external equipment to minimize and the related negative aesthetic effect of the numerous and diverse wiring of vehicle interior.Another welcome entertainment features is to use different portable media devices, as PC on knee, PDA, GPS equipment, game station or the like, thus with vehicle in other integrated equipment interactions.

[0015] broadcast source has been implemented or has been proposed in the literature from the several different methods of the audio frequency of portable audio player.In one approach, as the U.S. Patent Application Publication No. No.US2005/0049009A1 announcement of Yamamoto application, portable audio player is connected to " plug (plug) " equipment, and this equipment is assembled on the standard cigar lighter of vehicle so that power to the plug reflector.The plug device processes is AM or the FM radiobeam of frequency in the frequency spectrum of automobile wireless electricity equipment from the signal of portable audio player and with wireless launcher with its forwarding.Radiobeam is received by the vehicle standard wireless aerial, and is by its loudspeaker plays with the wireless device of vehicle from the music of portable audio player.In another approach, as disclosing among the U.S. Patent Publication No. No.US2003/0053378A1 of people such as Lovin application, the portable set (as cell phone or personal audio player) that comprises wireless transceiver transmits to interior second transceiver (or from its received signal) of cylindrical equipment (cylindrical apparatus).The signal that cylindrical device processes received and on the FM radio-frequency spectrum with its forwarding.Cylindrical equipment is directly connected on the wireless device of vehicle and by specifying the wireless device on the FM frequency that audio frequency is provided by coaxial cable.

[0016] these equipment all have shortcoming.For example, the quality of audio frequency is significantly than the poor quality near CD of most of portable audio players.FM and AM frequency band all lack the dynamic range of the sound that is used to reappear the higher quality related with portable music player.And traditional AM and FM frequency band are subject to the significantly influence of interference, and this interference is from the physical barrier that influences radio wave transmission with near other FM same frequency or this frequency and AM source.In brief, sound quality reduces.

[0017] in addition, these two kinds of methods all require to be directly connected to wireless device self, or by vehicle antenna (as the patent of Yamamoto) or by coaxial input (as the patent of Lovin).Therefore, for adopting data/address bus to connect the vehicle of multimedia equipment, the method for prior art all can not be utilized other relevant devices that are connected to bus.For example, in the situation of the portable music player that uses art methods, player can not be visited maybe can not be connected to any other equipment on the bus by interface, as discrete equalizer, and audio frequency amplifier or be used for recording musical and be provided with the integrated audio register that play the back.In cellular situation, phone can not access bus on separate microphone so that make interface allow the driver facing to microphone talk, and therefore sound is sent it back the caller through cell phone.In addition, itself hard wire of disclosed equipment requirements is connected to wireless device in the Lovin patent, causes installing more complicated and more difficult.

[0018] other art methods rely on wireless receiver are directly connected to wireless device, by auxiliary input device or by left and right sides stereo channel.These methods have same restriction, because they can not be connected by interface with any other equipment on the bus.

[0019] in addition, realize all-round (all-purpose) mechanism of ideal and the bus wireless interactive of any portable multimedia apparatus, and the feature on the parts of its connection increase bus and the very big flexibility of parts.At present, discrete portable media device can not be connected to any of most bus characteristics available on the multiple bus standard and function by interface.Therefore, the riding people of vehicle only can use the equipment that just is integrated into vehicle when making.
