Abstract
The invention relates to a system and method for transmitting audio data in a combined cabin management system in an aircraft with the steps: playing back entertainment programs and providing communications possibilities with an entertainment system (), which is connected to several first audio data sources () and to several first audio playback devices (), setting and displaying cabin parameters with a control system (), which is connected to several second audio data sources () and to several second audio playback devices (), transmitting audio data between the control system () and the entertainment system () with several audio channels () each with a coding device () and a decoding device () respectively. In order to be able to carry out the transmission of audio data and associated information by using commercially available coding chips with the lowest possible expense, the steps are provided: interlinking the audio signals from the several audio data sources () into one data stream through a multiplexer (), via which the coding device () is connected to several audio data sources (), and depacketing the data stream into audio signals for the several audio playback devices () through a demultiplexer () via which the decoding device () is connected to several audio playback devices (), wherein the audio data are transmitted between the coding device () and the decoding device () with a predetermined resolution.
