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).

Abstract: The invention refers to a method for updating an integrated display frame buffer of a display module in a mobile electronic device, comprising a local frame buffer and a processor, comprising the steps of transferring display information to said local frame buffer, updating said display frame buffer by transferring said display information from said local frame buffer to said display frame buffer, and displaying said display information on said display module. Furthermore, the invention comprises the additional steps of detecting changes of said display information stored in said local frame buffer, and updating said display frame buffer when a change of said display information in said local frame buffer is detected.
