ExDeus STB Firewire Driver Package allows you to connect your cable set-top-box (STB) to your Windows PC. The driver package is an updated packaging of Firewire drivers to support more STBs than previous packages. Note that the drivers do not change from release to release of the package; the same drivers are made to support more devices by adding the device names/IDs to the driver package, so there is no reason to update your drivers unless you are trying to use a new STB that wasn't supported earlier.

The following driver package includes Windows XP/MCE/Vista/7 Firewire drivers for various set-top-boxes manufactured by Scientific-Atlanta and Motorola. It includes a copy of CapDVHS, and the drivers and INF file from Tim M. Moore's firestb.msi installer, with the INF file updated to work with the following devices:

If you simply want to capture a Firewire stream (e.g., with CapDVHS), then all you need is the AV/C Tuner device. If you are using one of the Tim M. Moore-based driver packages (like the one downloaded from here), then you can select the device named for your STB. If your STB is not listed, then you can go through the manual driver install process.

A STB supports two relevant device profiles: AV/C Tuner and AV/C Panel. The Panasonic D-VHS driver is an AV/C Tape driver. You are installing an AV/C Tape driver for an AV/C Tuner device. That is why, with the original meitape.inf file, you have to uncheck the 'Show compatible hardware' box to select 'Panasonic D-VHS AV/C Device' (an AV/C Tape driver). With the firestb.inf file included in my package, hopefully your STB will already be listed without having to uncheck the 'Show compatible hardware' box.

Download the driver package and extract it to a convenient place on your hard drive. Connect your STB to your PC using the Firewire cable and follow the appropriate installation process:

Simple Installation

If you have issues installing a new driver or different driver versions, you can also uninstall the driver from your system completely.

1.      Uninstall the devices:

Open Device Manager, and for each STB device under Imaging devices, right-click and select Uninstall. When prompted, confirm the uninstallation.

2.      Remove the Windows driver services:

In Windows Explorer, navigate to the "drivers" folder where you extracted the STB driver package downloaded from this site. Double-click the "UninstallServices.reg" file to remove the services from the Windows registry.

3.      If you want to be very thorough, remove all oemXX.inf files for the STB drivers:

In Windows Explorer, navigate to the C:\Windows\inf folder. Search for all *.inf files containing the text "meituner". In Windows XP, this can be accomplished by clicking "Search" on the Windows Explorer toolbar; in "All or part of the filename" enter "*.inf"; in "A word or phrase in the file" enter "meituner"; click the "Search" button. Delete all oemXX.inf files that are found.

4.      Reboot.

I have made this driver package available because I plan to update it frequently as devices change. My package includes the most PnP Hardware IDs, which allows the driver to be installed on the most STBs. If the other driver packages were updated more frequently, you wouldn't need to download this one.

The DCT64xx Firewire capture and HD/SD to DVD guide from ReplayGuide uses a driver package also based on the Tim M. Moore drivers. It has not been updated in a bit, however, and so it does not support as many STBs. Follow the instructions there, but use this driver package instead.

There is also another driver package out there, in a zip file named "meidvhs.zip". It contains the original drivers as developed by Panasonic in 2001. All of the driver packages work similarly for Windows 2000/XP/Vista/7, although the ones based on the Tim M. Moore driver package (Tim's, mine, and ReplayGuide's) also support a Panel device for integration with Windows XP MCE or Vista Home Premium.

Below are some of the differences between the Panasonic (Matsushita) and Tim M. Moore (and variants) driver packages:

Copy protection (or Digital Rights Management) is a policy. It enumerates rights and restrictions for content. One method of implementing a copy protection policy includes a flag indicating the policy, and encryption enforcing the policy. Another method would be just a flag that expects a device on the receiving end to honor (i.e., the Broadcast Flag, Macrovision, etc.).

Broadcast/cablecast systems employ a variety of scrambling/encryption technologies to enforce copy protection / subscriber access policies but, in the case of Firewire as it used in cable STBs, the method of enforcing the copy protection is encryption. The authentication and encryption scheme used is called Five Company Digital Transmission Content Protection (5C DTCP). 5C DTCP uses Copy Control Information (CCI) flags to indicate the type of authentication and copy protection that is required. When you see "5C" or "CCI", both have to do with the Firewire output; neither have to do with the data stream delivered to your STB.

CCI 0x02 indicates a copy protection policy that stipulates copy-one-generation. But what is the copy protection? The copy protection is encryption.

In this context, there really isn't any point in distinguishing between something that is "copy protected" and "encrypted", because the copy protected content is encrypted.

You can use CapDVHS to see if a program is protected by 5C DTCP. Simply play the program from your DVR / live broadcast that you want to capture and start CapDVHS capturing to a file. If no values are populated on the "Data Info" tab, then the stream is encrypted and cannot be captured successfully.

The Broadcast Flag was a scheme designed to protected over-the-air (OTA) broadcast television from being recorded, copied, and redistributed. Fortunately, the Broadcast Flag was struck down by the U.S. District Court of Columbia.

Five Company Digital Transmission Content Protection (5C DTCP) is a protection scheme used on transport buses (devices directly connected by a cable), particularly the Firewire ports on cable STBs. It is a closed system, controlled by the Digital Transmission Licensing Authority (DTLA), implemented in hardware, and which can be continually updated, so it has not been "cracked" like DVD's CSS or HD-DVD and Blu-ray's AACS. 5C DTCP encryption is not used over the cable system, but can be controlled per channel or per program by a cable system for the Firewire output, so, in short, if a program is protected by 5C DTCP, you cannot capture it with a PC. Only a licensed device like a D-VHS deck will be able to record a 5C DTCP-protected stream to play back later. You may be able to capture the stream with a PC, but the resulting content will be unreadable, as the data is encrypted with encryption keys that change every 180 seconds.

It has been determined, by examining OTA broadcast streams, that some broadcasters have implemented the Broadcast Flag (formally known as the "Redistribution Control Descriptor", or RC_descriptor), even though equipment sold to consumers does not honor the flag to implement any form of copy protection. [ref]

Unfortunately, it also has been determined, empirically, that some cable STBs honor the Broadcast Flag and use it to apply to 5C DTCP to the Firewire output of local broadcasts. See the How to use a Motorola DVR wikibook to determine if 5C DTCP is being used by a Motorola cable STB. The 5C IMPLEMENTATION and CCI flags indicate whether 5C DTCP is being applied. Any value other than both being "NO"/"0x00" indicates encryption is being applied.

The DRM flag indicates whether the encryption is triggered by a cable program, and the RC Flag indicates whether the encryption is triggered by a local broadcast's Broadcast Flag.

The CCI flag seems to control the overall encryption, as situations have been found where a stream was set DRM 0x01 and CCI 0x00, and the program was successfully captured.

It is likely that the CCI flag values correspond to those established by the DTLA:

Copy Never (11 or 0x03)
Copy One Generation (10 or 0x02)
No More Copies (01 or 0x01)
Copy Freely (00 or 0x00)

"Copy One Generation" (0x02) does not refer to the initial recording on the DVR, but to one copy to a DTCP-compliant device, i.e., a DVHS deck.

A PC connected via Firewire is not DTCP-compliant, so no copying that requires authentication is allowed. That means only content marked "Copy Freely" (0x00) can be transferred to a PC, as all others require authentication.

There is one other situation that is possible, in which the STB uses 5C DTCP in Encryption Plus Non-assertion (EPN) mode. This leaves the CCI value at 0x00, but the content is still encrypted, so seeing a particular CCI value does not guarantee the stream can be recorded.

The FCC has rules that protect your right to record, in an unencrypted form, the local broadcast content in your area, even if it is relayed through a cable system. The trick is to get your local broadcast affiliates not to use the Broadcast Flag in their broadcasts, because of the reasons that follow.

Cable systems are governed by Code of Federal Regulations Title 47 Part 76 - MULTICHANNEL VIDEO AND CABLE TELEVISION SERVICE. The most relevant section reads:

§ 76.1909   Redistribution control of unencrypted digital terrestrial broadcast content.

(a) For the purposes of this section, the terms unencrypted digital terrestrial broadcast content, EIT, PMT, broadcast flag, covered demodulator product, and marked content shall have the same meaning as set forth in §73.9000 of this chapter.

(b) Encrypted retransmission. Where a multichannel video programming distributor retransmits unencrypted digital terrestrial broadcast content in encrypted form, such distributor shall, upon demodulation of the 8–VSB, 16–VSB, 64–QAM or 256–QAM signal, inspect either the EIT or PMT for the broadcast flag, and if the broadcast flag is present:

(1) Securely and robustly convey that information to the consumer product used to decrypt the distributor's signal information, and

(2) Require that such consumer product, following such decryption, protect the content of such signal as if it were a covered demodulator product receiving marked content.

(c) Unencrypted retransmission. Where a multichannel video programming distributor retransmits unencrypted digital terrestrial broadcast content in unencrypted form, such distributor shall, upon demodulation:

(1) Preserve the broadcast flag, if present, in both the EIT and PMT; and

(2) Use 8–VSB, 16–VSB, 64–QAM, or 256–QAM signal modulation for the retransmission.

(d) Unmarked content. Where a multichannel video programming distributor retransmits unencrypted digital terrestrial broadcast content that is not marked with the broadcast flag, the multichannel video programming distributor shall not encode such content to restrict its redistribution.

 

The most important part is that which I bolded, above, in subparagraph (d). Essentially, if the local broadcast isn't marked with the Broadcast Flag, then the cable equipment can't encrypt it. The flipside is that if the local broadcast does contain the Broadcast Flag, then the cable equipment must pass it on through the Firewire output. There are two possible scenarios that can then arise if the Broadcast Flag is present: 1) The cable provider is retransmitting the local broadcast in encrypted form, or 2) the cable provider is retransmitting the local broadcast in unencrypted form. Scenario 1, with encryption, means subparagraph (b) applies, and the cable STB must protect the content, presumably using 5C DTCP over Firewire. Scenario 2, without encryption, means subparagraph (c) applies, and the content doesn't have to be protected, but it does have to preserve the Broadcast Flag.

A response to an inquiry sent to the FCC reads as follows [ref]:

On September 10, 2003, the FCC adopted rules permitting TV sets to be built with
"plug and play" functionality for one-way digital cable services, which include
typical cable programming services and premium channels like HBO and Showtime.

FCC Rule Section 76.640, entitled, "Support for Unidirectional Digital Cable
Products on Digital Cable Systems," in subparagraph (a) notes that the
requirements apply to digital cable systems with one or more channels utilizing
QAM modulation for transporting programs and services from their head ends to
receiving devices. Cable systems that only pass through 8 VSB broadcast signals
shall not be considered digital cable systems.

Complaints alleging violations of FCC rules should be in writing briefly stating
facts and sent to:

Federal Communications Commission
Enforcement Bureau
445 12th Street, SW
Washington, DC 20554

OTA broadcasts use 8VSB modulation, while digital cable systems use QAM. When digital cable systems carry OTA broadcasts, they receive the 8VSB signals and rebroadcast them over the cable system using QAM. Most cable systems do not exclusively pass through 8VSB broadcasts, they bundle them with their own QAM channels, qualifying them under the FCC's definition of a digital cable system.

If you would like other STBs added to the list of devices, send a PM or post a reply at AVS Forum.

All other questions should be posted at large to the AVS Forum thread.
