MOST Applications

The applications below show simple MOST devices. They are the basic building blocks that can be used by more complex devices such as audio and video sources, consumer interfaces, video displays and amplifiers and other devices used to implement sophisticated information and entertainment systems. Consumer devices always have analog interfaces in addition to a changing variety of digital interfaces. These applications also provide the most flexible way to connect external devices to an on-board network.

Analog Audio Gateways

The simplest MOST applications consist of analog audio gateways. A simple Digital-to-Analog Converter (DAC) can be connected to a MOST transceiver to drive a speaker. A Human Machine Interface (HMI) sets up the MOST transceiver to receive data from a specific channel and the transceiver drives the DAC clock based on the timing provided by the network timing master. Since both the receiver and the sender of the data are running off the same clock, no special buffering or processing of packet information is required. The MOST transceiver even provides industry-standard to connect to off-the-shelf DAC's from many manufacturers.

A microphone can be connected to an Analog-to-Digital Converter (ADC) that in turn connects directly to a MOST transceiver. The HMI sets up the communication channel and the ADC just streams its data to the MOST transceiver.

Analog Video Interface

Digital Video Display Interface

The video signals previously captured can be decoded by a video display interface. This interface could even take care of any copy protection mechanisms that were used if the data came from a DVD.
