MOST® Stream Transmission Specification Released

  • MOST® Cooperation Specifies CI+ Content Protected Transmission over MOST

The MOST® Cooperation – the standardization organization for the leading automotive multimedia network Media Oriented Systems Transport (MOST) – has released its latest MOST Stream Transmission Specification that includes support for the MOST CI+ Interim License Agreement issued by the CI Plus LLP. CI+ now allows a MOST network to transport CI+ protected content using Digital Transmission Content Protection (DTCP).

“We are happy to work together with the MOST Cooperation to enable the adoption of CI+ in the dynamic automotive world,” said Laurent Molac, Spokesman of CI Plus LLP, Guildford, UK. CI+ is a technical specification that adds additional security and features to the proven DVB Common Interface Standard. CI+ compatible consumer electronic devices, such as Integrated Digital Televisions and Set Top Boxes, can access a wide range of Pay TV Services via plug-in CI+ Modules wherever the CI+ Technology is supported by the local Pay TV Provider.

“This agreement with the CI Plus LLP enables the transmission of the latest digital video broadcasts to be transported between vehicle components over the widely used MOST network,” said Henry Muyshondt, Administrator of the MOST Cooperation. “MOST Technology has been at the forefront of supporting digital content protection since it became the first high speed network to be able to transport DVD content back in 2003.”

The MOST Cooperation has optimized the MOST network for high quality video streaming. MOST150 enables direct isochronous transport of, for example, MPEG video streams without bit-stuffing or transcoding. In addition to the approved content protection schemes for Digital Transmission Content Protection (DTCP) and HDCP, MOST allows to transport CI+ protected content.
