Definitions
- Such a method is known from European laid-open specification 0 865 170 AI.
- audio information from a hi-fi system operating as a hi-fi signal source is first compressed using the ATRAC method.
- the audio signals compressed in this way are then transmitted in the DECT standard (DECT: Digital Enhanced Cordless Telecommunications) to a hi-fi signal sink.
- DECT Digital Enhanced Cordless Telecommunications
- the hi-fi signal sink can be, for example, headphones, speakers or amplifiers.
- MP3 compression is understood to mean compression according to the MPEG Layer-3 standard (ISO-MPEG Audio Layer-3 (eg IS11172-3 or IS13818-3)).
- the user of the hi-fi headphones could select the audio signal that he would like to hear.
- the method according to the invention in contrast to the previously known DECT transmission method, only a single Bluetooth radio channel is always used, as a result of which a flexible system is realized in which audio signals from different hi-fi signal sources can be received simultaneously.
- a remote control device is used to control the at least one hi-fi signal source and / or the at least one hi-fi signal sink, which controls its control signals in the above-mentioned Bluetooth radio channel to the at least one hi-fi signal source and / or the at least one sends a HiFi signal sink; because according to this development of the method according to the invention the why use the existing Bluetooth radio channel to transmit the audio signals and also to transmit control signals.
- the object of the invention is to further develop it in such a way that audio signals from a plurality of hi-fi signal sources can be received simultaneously.
- a hi-fi signal source with a radio device for transmitting compressed audio signals to a hi-fi signal sink is known from the European patent application mentioned at the beginning.
- a hifi signal source it is to be achieved according to the invention that it can be operated together with further hifi signal sources in such a way that audio signals of several hifi signal sources can be transmitted simultaneously to one or more hifi signal sinks.
- FIG. 1 shows an exemplary embodiment of an arrangement with which the method according to the invention can be carried out.
- FIG. 2 shows an embodiment for a hi-fi signal sink according to the invention, and
- FIG. 3 shows an embodiment for a hi-fi signal source according to the invention.
- FIG. 1 shows a Bluetooth microcell 10 which is formed by a hi-fi signal source 20, a further hi-fi signal source 30, a hi-fi signal sink 40 as well as a further hi-fi signal sink 50 and a remote control device ST.
- the two hi-fi signal sources, the two hi-fi signal sinks and the remote control device ST are connected to one another in a Bluetooth radio connection, which is shown schematically in FIG. 1 by arrows with the reference symbol 60.
- the Bluetooth radio connection is formed by a single Bluetooth radio channel. In this Bluetooth radio channel, the data signals are transmitted at a data rate of up to one megabit per second.
- the hi-fi signal source 100 can be operated as follows: Audio information SI from the audio signal source 110 reaches the MP3 coding device 120 via the output AHO of the audio signal source 110. In the MP3 coding device 120, the audio information is MP3-coded with the formation of compressed th audio signals SI. These compressed audio signals SI * arrive at the Bluetooth radio device 130, which sends the compressed audio signals SI 'as Bluetooth radio signals SI ".
- FIG. 3 shows an exemplary embodiment of a hi-fi signal sink 200.
- the hi-fi signal sink 200 has a Bluetooth receiving device 210 which is followed by an MP3 decoding device 220 with its data input D220 at an output A210.
