Embodiments are also possible in which the receipt of the specific release signal, which can also be a change signal, causes the assignment of a possible value to information about a data record to be changed to the assignment of this value to information about one data record and information about another data record. For example, the possible value of the identifier can be assigned to a sequence of information about data records.
In a preferred embodiment, the specific release signal, preferably a release signal designed as a change signal, is assigned to a single, specific data record. The specific data record stored in the memory of the computer can only be called for the control unit of the playback device via the data line when the control unit of the computer has received a specific release signal for this specific data set. In a preferred embodiment, the ability of the control unit calling up another data record stored in the memory of the computer remains unaffected by the reception of the specific release signal. If the other data record is released for retrieval, it remains released. If the other data record is locked, it remains locked and is only released when the control unit has received the specific release signal for the other data record.
In a preferred embodiment, the computer is a server or a computer of a network of computers connected to a cloud.
In a preferred embodiment, the data line is a direct radio line between the playback device and the computer, for example a connection via a WLAN or a connection via Bluetooth or NFC. In an alternative embodiment, the data line is a connection over the Internet.
