Most specifications have continuously been amended and extended in order to narrow the possibility for different interpretations by implementers.
Automotive network supports video applications
MOST150 features an isochronous transport mechanism to support extensive video applications, as well as an Ethernet channel for efficient transport of IP-based packet data.
MOST150 enables direct isochronous transport of MPEG video streams without bit-stuffing or transcoding.
The MOST standard supports approved content protection schemes and therefore enables digital transmission of DVD Audio, DVD Video, HD-DVD and Blu-ray content.
With the integration of DVD audio and DVD video into digital networks, the requirement for content protection comes into place.
DVD content on a digital network must be DTCP (digital transmission content protection) protected.
MOST was the first network to be fully approved by the DVD Copy Control Association (DVD CCA) to carry DTCP- protected content.
This was made possible by adapting DTCP to the MOST standard.
HD-DVD and Blu-ray content on MOST is supported since AACS (advanced access content system) licensing allows digital outputs which are protected using DTCP.
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.
With MOST150, the integration of DVD applications into vehicles is no longer an issue - even when streaming the full-quality equivalent bandwidth.
In addition to much higher bandwidth MOST150 offers an isochronous channel to support streams which are not synchronised to the MOST frame rate.
Like with MOST25 and MOST50, application developers can take advantage of secure pipes for transferring sensitive content.
DTCP solutions for MOST are available in hardware as well as in software from various suppliers.
