CableCard Description

A CableCARD is a PCMCIA, Type II PC Card. The CableCARD is used in place of a set top cable decoder box, and plugs into the HD TV to provide the cable decoder function.
Other terms include Digital Cable Ready [DCR].
The S-Card works with Single-Stream data only [in the S-Mode]. S-Mode CableCARDs [S-Card] were only capable of decrypting a single stream, therefore requiring devices with multiple tuners, such as most digital video recorders, to include two CableCARD slots.
The S-Mode of CableCard is an early version, replaced by M-Mode [M-Card]. An M-Card will operate in Multi Stream Mode or Single Stream Mode.
The S-Card may or may not work in an M-Mode Host.

The PC Card PCMCIA specification defines both the Electrical and Physical specifications for a 68 pin interface residing in one of 3 form factors, which differ only in thickness;
Type I: dimensions 3.3mm x 85.6mm x 54.0mm (TxLxW), Version 2.1 allows the length to increase 50mm to 135mm
Type II: dimensions 5.0mm x 85.6mm x 54.0mm (TxLxW), Version 2.1 allows the length to increase 50mm to 135mm
Type III: dimensions 10.5mm x 85.6mm x 54.0mm (Tall x Length x Width)

The implementation of this spec based on the ISA bus is termed the PC Card with a 8/16 bit data bus, 26 address lines, and no bus mastering. PC Card-16 cards use an 8-bit or 16-bit interface that operates at ISA bus speeds (10 MHz) using an ISA-like asynchronous protocol.
All of the PCMCIA implementations use Plug and Play and have Hot Swapping capabilities. The 16-bit PCMCIA 'PC Card' will operate up to a maximum of 20MBps, or 160Mbps.
The actual throughput will depend on the minimum cycle time and the transfer mode and will never reach the maximum throughput rates.

Comparison of Removable Memory Card sizes

Flash memory cards vs. PC Card format.

CableCard is a PCMCIA slot and PCMCIA card, a tuner card that can be inserted into a slot in the TV to replace a cable set-top box.

Some TV descriptions indicate the term CableCard, while others indicate Digital Cable Ready [see below]. I was only able to find a few HDTV units from Hitachi which came with a CableCard slot. I see a few from Sony too. The CableCard allows the user to plug cable directly into a TV set without the need for a set-top box [STB]. CableCard slots may also be found on Divigal Video Recorders [DVR]

Version 1 of CableCard was 'one-way' only so with out the cable decoder box things like 'pay-per-view' was unavailable. Version 2 released in June 2007 should be fixing this problem [I have not yet reviewed it]. As of July 07 according to an FCC ruling; cable companies now have to supply set-top boxes that come with a removable CableCard. The ruling may bring CableCard back from the dead. However by December 2009 it would appear that the FCC is not happy with how poorly the adoption of CableCard has been.

Digital Cable Ready [DCR], this attribute describes a TV that incorporates a CableCARD slot to facilitate the reception of one-way digital cable content (which may include analog, digital, high-definition and/or premium programming) without the need for a set-top box. A CableCARD is typically provided for a nominal monthly fee by the cable provider. Sets may also use the term Digital Cable Turner.

PCMCIA Connector Manufacturers

The PC Card uses a 68 pin connector, with two rows of 34 pins, with 0.05 inch spacing [1.27mm]. Female pins are used on the card side, male pins on the system end.
The power and ground pins are longer than the signal lines, allowing them to make connect first.
