The Most Data Protocol

The data to be transmitted are divided into data packets, or so-called frames. Each frame in the MOST150 data bus is 3072 bits long (MOST25 = 512 bits). The useful digital data length is 3040 bits (MOST25 = 480 bits). This means that significantly more information is transmitted per data packet in the MOST150.

The overall length of a frame has:

• A data field for administrative purposes
• A data field for control data
• Two data fields

The data are transmitted through three channels (control, synchronous and asynchronous):

• The control channel transmits control data
• The synchronous channel transmits audio and video data transfer (synchronous real-time transfer without buffering)
• The asynchronous channel transmits greater amounts of data, such as metadata of audio files (asynchronous, event-driven data transfer, buffering possible)
