CABLECARD M-CARD
M-CARD SCOPE
This specification defines the normative characteristics for the interface between a security module, owned and
distributed by cable operators, and commercially available consumer receivers and set-top terminals; host
devices that are used to access multi-channel television programming delivered on North American cable
systems. Some examples of host devices are set-top boxes, televisions, and VCRs. In some cases, a local
cable operator may choose to supply this host device in addition to the security module. In order to receive
scrambled cable services, the Host would require this security module, called a CableCARD
inserted and authorized to receive services. This CableCARD device, previously identified as a Point of Deploy-
ment (POD) module, provides the conditional access operation and the network connectivity for the Host.
This CableCARD device-Host Interface (CHI) specification defines the interface between the Host device (Host)
and the CableCARD device (Card).
There are currently two modes of operation in which the Host and the Card can operate. The Single-Stream
CableCARD device (S-CARD) is the first generation security module that can only operate in the Single-Stream
Mode (S-Mode), and the Multi-Stream CableCARD device (M-CARD), is a second-generation variant that is
capable of operation in either Multi-Stream Mode (M-Mode), or in Single-Stream Mode (S-Mode), based on the
Host and its available functionality.
This document defines the interface for both the S-CARD and the M-CARD and the different operating modes.
The M-CARD, when operating in S-Mode, is backward compatible with the Single-Stream CableCARD Host
Interface as previously defined via ANSI/SCTE 28, the Host-POD Interface Standard, and ANSI/SCTE 41, the
POD Copy Protection System. When the M-CARD is running in M-Mode, functionality to support multiple
program decryption from multiple transport streams is added. One application for the M-CARD could be a Host
device with multiple tuners and QAM demodulators.
While analog television channels may be tuned, only digital television channels will be passed through the
Card for descrambling of authorized conditional access channels, and passed back to the Host. The Card will
not only provide the conditional access decryption of the digital television channel, but MAY also provide the
network interface between the Host and the cable system.
This document is a compilation of the specifications, standards, and related text from the OpenCable Specifi-
cation CableCARD Interface documents, single stream and multi-stream, OC-SP-CC-IF and OC-SP-MC-IF, as
well as the SCTE 28, 2004 documents. For the text that was extracted from the SCTE 28 2004 document, in
all cases, the terms "POD" and "POD module" were replaced with the terms "Card" and "CableCARD device".
M-CARD Introduction and Overview
This specification defines the characteristics and normative specifications for the interface between the Card
device and the Host device. This specification describes the interface for both the Single Stream Card and the
Multi-Stream Card.
• Single Stream Card (S-CARD) for use with or between Cards and Hosts capable only of processing
a single program on the interface is said to be operating in Single Stream Mode (S-Mode).
• Multi-Stream Card (M-CARD) for use between a Card and Host both capable of processing multiple
simultaneous programs on the interface is said to be operating in Multi-Stream Mode (M-Mode). The
MCARD, when instructed to do so by the Host, can operate in S-Mode. The M-CARD can only operate
in either M-Mode or S-Mode, not both.
This specification supports a variety of conditional access scrambling systems. Entitlement management
messages (EMMs) and Entitlement Control Messages (ECMs) across the interface for such scrambling
systems are carried in the cable out-of-band channel as defined by [SCTE55-2], [SCTE55-1], and the
DOCSIS® Set-top Gateway Specification [DSG].
