CABLECARD M--CARD
The interface will support Emergency Alert messages transmitted over the out-of-band channel to the Card
which will deliver the message to the Host using the format defined in [J042]. This specification defines,
sometimes by reference, the physical interface, signal timing, link interface, and application interface for the
Card-Host interface (CHI).
1.2 Historical Perspective (Informative)
Portions of this specification have origins in EIA-679, the National Renewable Security Standard, which was
initially adopted in September 1998. Part B of that standard uses the same physical size, shape and connec-
tor of the computer industry PCMCIA card defined elsewhere, and defines the interface protocols and stack.
Part B of that standard was adopted by SCTE DVS.
Further extensions and modifications of EIA-679 led to the adoption of EIA-679-B in 2000. The EIA-679 stan-
dard was developed substantially by the EIA/NCTA Joint Engineering Committee (JEC) National Renewable
Security Standard (NRSS) Subcommittee, and was a joint work of NCTA and CEMA Technology & Standards.
The M-Mode specification has its origin in ANSI/SCTE 28, where the original version of the Card provided only
enough bandwidth for a S-Mode. As DVRs, picture-in-picture, and other M-Mode features were developed, it
was realized that the original S-Mode had inadequate bandwidth for some of these features, and could not
grow to support multi-tuner gateway scenarios.
A M-Mode provides the higher transport data throughput rates that would be required to support future features,
such as multiple-tuner Hosts, Hosts with DVRs, Hosts with picture-in-picture capability, and future extensions
of existing conditional access functions to include Digital Rights Management.
This specification document is based on and conforms to much of the technical content as found in ANSI/
SCTE 28, 2004.
