MOST helps car companies connect to the consumer world. MOST operating as the network backbone in the car complies with the robustness and reliability requirements of the automotive industry and provides a pipeline for moving audio, video and, in its latest generation, IP based data. Automobiles evolve in fundamentally different time frames than consumer electronics products, with the consumer electronics industry moving at a much faster pace. The major innovations in both industries, however, do follow similar timelines. MOST provides a way to decouple the automotive product lifecycles from consumer product lifecycles. The technology provides a way to build-in major technological advances into the automotive system, even as they evolve, while relegating specific and rapidly changing consumer interfaces to gateways attached to the vehicle backbone. It is even possible to build a consumer gateway an accessory that could be upgraded over time. With the integration of DVD Audio and DVD Video into digital networks, content protection has become a requirement. DVD content on a digital network must be DTCP protected. MOST was the first network to be fully approved by the DVD Copy Control Association (DVD CCA) to carry DTCP protected content. HD-DVD and Blue-ray content over MOST is also supported since AACS (Advanced Access Content System) specifications allow digital outputs which are DTCP protected. DTCP requires source and sink devices to authenticate each other. In addition, there is a need to encrypt multimedia streaming data before sending it over a digital network. A sink device therefore has to be able to decrypt protected digital content. DTCP on MOST also supports point-to-multipoint connections. The single phases consist of authentication (320 Bit public device key), key exchange (Elliptic Curve DH) as well as encryption and decryption (M6-56Bit, AES-128Bit). With the 'MOST Specification Rev. 2.5' the MOST Cooperation doubled the bandwidth for automotive infotainment solutions from 25 to 50 Mbps. The MOST Specification of Electrical Physical Layer Rev. 1.1 is an additional key specification that enabled data transmission over unshielded copper wires while meeting the stringent automotive electromagnetic compatibility requirements.
