Since the MOST System transmits the audio data synchronously, additional data buffering is not needed. This reduces the complexity of the device and thereby saves costs. In addition, The most typical data type is synchronous, which represents multimedia data and occupies the largest configurable portion of the frame. Asynchronous data is used to support multi-media information such as GPS systems, information about accessed files, and data of capsulated protocols within the MOST system. [16]
1. Most 25 Frame
A MOST25 frame consists of 512 bits or 64 bytes with sampling rate equals to 44.1kHz. Sixty bytes are used for the transmission of stream and packet data. Two bytes transport one part of the control message that is made up of a total of 32 bytes for the administration of network and nodes such as the transmission of the channel resource allocation table.
