Abstract: The present invention relates to a method for determining the format of an optical recording medium (1) comprising one or more data, audio and/or video tracks in one or more sessions, and an apparatus for reading from and/or writing to optical recording media (1) using such method. It is an object of the present invention to propose a method for determining the format of an optical recording medium (1), which is robust against partially incorrect data on the recording medium (1).

Abstract: The present invention relates to a user interface for a multimedia device having means for navigating within a plurality of multimedia files and/or means for changing a playback order. According to the invention, the user interface includes means for changing the sorting order and/or playback order of the plurality of multimedia files, whereby upon changing the sorting order and/or playback order of the multimedia files the currently selected multimedia file is kept and the new sorting order and/or playback order is determined by at least one property of the currently selected multimedia file, wherein the means for changing the sorting order and/or the playback order include a button for changing the order by running through a predefined sequence of properties of the currently selected multimedia file.

Abstract: The invention relates to a serial data transfer method for exchanging data between two electronic bus stations. The bus connection consists of two lines, the first line being dedicated to data/control signals and the second line being dedicated to a power supply voltage. Data transfer is started by pulling the first line to an activated potential for a first period of time, and then leaving the first line inactive for a second period of time. Data transmission commences via the first and second lines after the second period of time has elapsed. Preferably, data is transferred in a number of blocks in the data frame.

Abstract: The invention relates to a simple serial data transfer method for the exchange of data between two electronic bus stations. The bus connection consists of two lines wherein the first line is dedicated to data/control signals and a second line is dedicated to a power supply voltage. A data transfer from the transmitting station to the receiving station is started by pulling the first line to an activated potential for a first period of time. After elapse of the first period of time the transmitting station leaves said first line inactive for a second period of time. The transmitting station commences data transmission via said first and second line after elapse of said second period of time. Preferably, data is transferred in a number of blocks in the data frame. The first block concerns a synchronization block and the last block is a checksum block.
