Abstract: A key selection vector for a revocation list in an HDCP system as well as a mobile device and a method for processing a key selection vector, a digital content output device using a key selection vector and a revocation list for use in an HDCP system comprising a key selection vector are described. It is desired to improve handling of key selection vectors of revocation lists. A structured key selection vector for a revocation list is provided. The key selection vector is structured to contain at least one bit field with a predetermined number of bits and at a predetermined location in the key selection vector. The bit field contains information relating to a group property of a device, which group property allows to process as a group a plurality of key selection vectors storing the same or similar group property information in said at least one bit field.

Abstract: A portable electronic device includes a data input/output (I/O) circuit for communicating data to/from the electronic device, first logic operative to control the data I/O circuit in accordance with a first data transfer standard, wherein the first data transfer standard defines a first connector pin out, and second logic different from the first logic and operative to control the data I/O circuit in accordance with a second data transfer standard, wherein the second data transfer defines a second connector pin out different from the first connector pin out. The device also includes switching logic operative to selectively couple the first logic or the second logic to the data I/O circuit so as to enable operation of the data I/O circuit in accordance with the first data transfer standard or the second data transfer standard.

Abstract: This invention discloses a mobile communication equipment operable to automatically select a television standard according to the mobile communication network said equipment is located in. Since different television standards need specific demodulation, respectively, it is essential to select the correct television standard like e.g. PAL or NTSC to receive proper images and films. This object is solved by a mobile communication equipment adapted for wireless communication in a wireless communication system, comprising an analysing device being operable to determine a television standard, said analysing device comprising a determining device operable to automatically determine country-specific data, and a mapping device operable to map said country-specific data to a specific television standard.

Abstract: In a communication system, an authentication ciphering offset (ACO) is generated as a function of one or more parameters, wherein at least one of the one or more parameters is derived from earlier-computed values of the ACO. This enables each device to avoid generating an ACO value that is out of synchronization with a counterpart ACO value generated in another communication device.
