Abstract: A device (1) (and corresponding system, method and computer program product) comprises at least a first control block (2), a second control block (3), a bus (9) between the first control block (2) and the second control block (3) for transmitting information between the first control block (2) and the second control block (3), an electro-acoustic converter (5) adapted to the first control block (2) for generating an audible signal on the basis of an audio frame, video presentation means (3.8, 4) for presenting video information on the basis of video frames, and a synchronizing parameter (3.12) for synchronizing the presentation of video information to the presentation of audio information. The first control block (2) is adapted to transmit a request message to the second control block (3) for requesting an audio frame to be transmitted from the second control block (3) to the first control block (2).
