DCR & CableCARD

DIGITAL CABLE READY HDTV
A plug-and-play DTV is a television that you can plug directly into your cable system and receive analog and most digital cable services without the need for a set-top box. The cable and consumer electronics industries have dubbed these types of televisions digital cable ready or DCR.
Great Company Great People

CableCARDTM

Digital plug-and-play will not work quite like analog. For digital plug-and-play, youll probably need to get a security card (also known as a CableCARDTM) from your local cable operator. The security card will permit you to watch scrambled programming and premium services, to which youre subscribed.

CEA-NCTA Agreement

Signed at Dec 19, 2002 An agreement between cable operators and the consumer electronics industry How to offer digital programming over cable lines to current and future digital televisions without the need for a set-top box Unidirectional" cable-ready digital television sets (called UDCP or UDRD) Conditional access mechanism Separate CableCARD(POD) card Only receive information from the headend (one-way) Cable industry : Comcast, Cox, Time Warner, etc. (8 companies) CE industry : Philips, Panasonic, Zenith, Samsung, Sony, etc (14 companies)
CEA : Consumer Electronics Association NCTA : National Cable & Telecommunications Association POD : Point-Of-Deployment UDCP : Uni-Directional Cable Product, UDRD : Uni-Directional Receiving Device
First Verification started at Feb 2004 (VW18) based on PICS/ATP DCR TV can receive Off-air HD / HD through cable Off-air/Cable Analog & Digital But, DCR TV doesnt support VOD, Impulse PPV EPG service provided by MSO

Authorization & Validation Processes
In order to activate CA service(called low-value service) and to receive Cable channel map, Authorization process is needed. Serial number and CableCARD ID is needed. During this process, CableCARD reset may be occurred. After this process is finished with successful, user can navigate cable channel map & can watch CA Encrypted services which is subscribed by the user. In order to activate CP service(called high-value service) also, Validation process is needed. Host/CableCARD ID is needed. HeadEnd sends Validation message through OOB channel. After Validation message is received into the CableCARD, user can watch CP Encrypted services also.

DCR Functionalities

Conditional Access Function Copy Protection Function Cable menu & MMI(Man Machine Interface) Function Digital Certificates CableCARD reset Function EAS(Emergency Alert System) Function Host Diagnostics Function CableCARD Firmware Upgrade Function Error Reporting Function
Cable Menu & MMI(Man Machine Interface)
Using Cable Menu, user can check status of various CableCARD
functions. - The lists of this menu is vary, depending on the CableCARD manufacturer.
Cable Menu Example : SA CableCARD case
CableCARD uses MMI(Man Machine Interface) function to
communicate with the user. - CableCARD displays various user notification information through MMI window - Host/CableCARD ID information - the error reporting of Hosts certification data
MMI Example : SA CableCARD case
Digital Certificates Data Digital Certificates Data
Every TV and CableCARD has Digital Certificates Data to identify itself. Host/CableCARD ID is determined from the value of each Digital Certificates Data. CableCARD side invalid Certificate case Please call your cable operator and report an invalid CableCARD error message will be displayed.

DTV side Invalid or Without Certificate case There was a technical problem during the authorization process. This production may have some component failure or may not be designed to be fully compatible with digital cable television service. Please contact the manufacturer or the retailer. MMI message will be displayed.
CableCARD Reset CableCARD Reset
When the DCR TV or CableCARD think other side go into abnormal state, set CableCARD reset to recover Host/CableCARD interface. 161-xx technical problem case. Even when the normal state but Host/CableCARD interface is needed to reboot, set CableCARD reset. CableCARD firmware upgrade case. HeadEnd Authorization case. There is two type of CableCARD reset PCMCIA reset(Cold reset, H/W level reset) POD reset(Worm reset, S/W level reset) When the CableCARD reset is occurred, and if user is watching CA or CP Encrypted service at that time, A/V still effect will be occurred during about 20 seconds.
EAS(Emergency Alert System)

Tornado

EAS (In-band, OOB)

Host Diagnostics

To check the state of various TV functions related to the CableCARD, uses Host Diagnostic menu. - press Menu->CABLE->0->0->0 to get into Host Diagnostics menu. - Cable Channel Lists status - FAT, FDC status - H/W & F/W version
CableCARD Firmware Upgrade
When the CableCARD Firmware Upgrade is needed, HeadEnd activates CableCARD Firmware Upgrade operation. Delayed Upgrade mode (only at the stand-by state) Immediate Upgrade mode (stand-by or power-on state) CableCARD Firmware Upgrade shouldnt be interrupted by other operation. During this operation, CableCARD Firmware Upgrade reporting message is being displayed and whole remote control key will be disabled with temporary. Only SA uses CableCARD Firmware Upgrade protocol and SA uses inband tuner for this operation. Motorola uses their unique technique for the CableCARD firmware Upgrade and uses OOB tuner for this operation.

Error Reporting

By the standard(SCTE28 Appendix E), in the case of pre-defined error case, DCR should display Error Reporting called 161-xx technical problem and/or set CableCARD reset to recover this error status. Failure mechanism is not the DCR but the CableCARD. xx digits are the index of this error.
