An apparatus for processing audio and/or video data comprising: - a module for displaying an element comprising at least one absolute time or at least one time indicator; - wherein a sector (107, 202, 401, 1301, 1302, 1303) associated with the element indicates a duration or a length of the audio and/or video data; - wherein time marks are displayed that are set automatically or by user interaction; - a line pointer that points to the sector (107, 202, 401, 1301, 1302, 1303) or to a position within the sector (107, 202, 401, 1301, 1302, 1303) indicating an actual position within the audio and/or video data; - wherein the element displayed has a shape of at least a portion of an analogue clock; - wherein the displayed element has a disc-like representation; - wherein the sector is arranged inside the displayed element, the sector indicating a length or a duration of first program material stored in a first buffer providing buffering functionality for a first program channel (b), and wherein a further sector is arranged inside the displayed element, the further sector indicating a length or a duration of second program material stored in a second buffer providing buffering functionality for a second program channel (a); - wherein a parallel recording in the first and in the second buffer is visualized via overlapping of the sector and the further sector; - wherein the line pointer is for the first and the second buffer, and is movable by appropriate trick play operations by a user, and wherein a program channel change leads to live TV output of the program channel (a, b) changed to and with the line pointer moving to the current time. - a module for displaying an element comprising at least one absolute time or at least one time indicator; - wherein a sector (107, 202, 401, 1301, 1302, 1303) associated with the element indicates a duration or a length of the audio and/or video data; - wherein time marks are displayed that are set automatically or by user interaction; - a line pointer that points to the sector (107, 202, 401, 1301, 1302, 1303) or to a position within the sector (107, 202, 401, 1301, 1302, 1303) indicating an actual position within the audio and/or video data; - wherein the element displayed has a shape of at least a portion of an analogue clock; - wherein the displayed element has a disc-like representation; - wherein the sector is arranged inside the displayed element, the sector indicating a length or a duration of first program material stored in a first buffer providing buffering functionality for a first program channel (b), and wherein a further sector is arranged inside the displayed element, the further sector indicating a length or a duration of second program material stored in a second buffer providing buffering functionality for a second program channel (a); - wherein a parallel recording in the first and in the second buffer is visualized via overlapping of the sector and the further sector; - wherein the line pointer is for the first and the second buffer, and is movable by appropriate trick play operations by a user, and wherein a program channel change leads to live TV output of the program channel (a, b) changed to and with the line pointer moving to the current time.
