Abstract: A method for carrying out an application with the help of a portable data carrier, wherein the data carrier includes two separated communication interfaces. According to the method, a user transmits via a first terminal specified input data for processing by the application to a server via a first data connection between the first terminal and the server. Then, authentication data for authenticating the application based on the input data of the server are transmitted via a second data connection between the server and the data carrier which is connected via the first communication interface with the first terminal. The authentication data are then transmitted from the data carrier via a third data connection to the second terminal. The third data connection is realized by means of the second communication interface.

Abstract: In the case of a method for transformation encoding of moving-image sequences, motion vectors are estimated block-by-block, with which said motion vectors a motion compensation is carried out. The prediction error is transformation-encoded. According to the invention, the block size of the transformation encoding is coupled to the block size used in each case for the motion compensation. This measure makes it possible to enhance the efficiency of the encoding of the prediction error in hybrid encoding procedures that use various block sizes.
