Abstract: A source device for providing audio data and video data on one or more digital media interfaces is described, wherein the source device is configured to automatically adjust a time alignment between a provision of audio data and a provision of video data based on an information about a latency of an audio path and based on an information about a latency of a video path.

Abstract: An apparatus for determining a position of an object relative to a representation of an image to be represented includes a position pattern generator for generating a position pattern subdivided into a plurality of pattern portions, each of the pattern portions having an unambiguous bit pattern of a plurality of bit patterns, and the bit patterns being Gray-coded in a generalized manner; a combination unit for combining the position pattern with the at least one image to be represented and for providing a corresponding combined image; an optical sensor for optically sensing an image section of the combined image, being correlated with the object position; a filter for extracting at least one bit pattern corresponding to a pattern portion of the position pattern, from the image section and for providing at least one corresponding extracted pattern portion; and a determiner for determining the object position based on the extracted bit pattern.

Abstract: A device for controlling a service access authorization for a user device with regard to an access-restricted service includes a service access authorization provider, the service access authorization provider being configured to set a period of time in which the service access authorization is valid, responsive to an authorization message provided with a service-dependent user identifier, and the service access authorization provider being configured to disable an authorization allowing the service access authorization to be extended or reactivated using the previous service-dependent user identifier when at least a predetermined duration has passed since an end of a last authorization time interval for which a service access authorization was determined by the device.
