摘要： A method for wireless data transfer between a first multimedia device (CAMC) and a second multimedia device (TV), which first multimedia device (CAMC) and second multimedia device (TV) are connected via a wireless connection that is operated according to a first wireless standard (BT) or to a second wireless standard (IEEE802.11b), which first wireless standard (BT) and second wireless standard (IEEE802.11b) are different from and/or not compatible with each other, said method comprising the following steps: a choosing step in which said first wireless standard (BT) or said second wireless standard (IEEE802.11b) is chosen as chosen wireless standard; an adaptation layer processing step in which connection commands (BT-CC), connection parameters (BT-CP) and/or connection data (BT-CD) are processed in order to obtain processed connection commands (IEEE802.11b-CC), processed connection parameters (IEEE802.11b-CP) and/or processed connection data (IEEE802.11b-CD) of said chosen wireless standard (IEEE802.11b; 802.11a; BT); and a sending step in which said processed connection commands (IEEE802.11b-CC), processed connection parameters (IEEE802.11b-CP) and/or processed connection data (IEEE802.11b-CD) are sent out via said wireless connection (IEEE802.11b-WC) according to said chosen wireless standard (IEEE802.11b; 802.11a; BT). The method thus enables a seamless switching from one wireless standard to another wireless standard, wherein upper layers do not notice the switching.
