Digital Cable Advisor lets you know if your Windows 7 PC is Digital Cable Ready

Adding a CableCARD™ TV tuner is really the pièce de résistance in creating a full-featured Windows Media Center PC because it is the only way that US-based users can bring high definition, premium digital cable content directly into their PCs without using a set-top box. If you use Windows Media Center to manage your television and DVR needs, and you subscribe to a lot of premium  channels in your cable plan, then a CableCARD tuner makes great sense for you.

When CableCARD™ tuners first hit the market a few years ago, however, they required a Digital Cable Ready PC. At the time, these could only be obtained from an original equipment manufacturer, which was very much to the chagrin of DIYers and enthusiasts who were eager to round out their Home Theater PCs with a robust digital cable experience.

All of this changed with Windows 7, however. The OEM-only requirement was lifted and DIYers were free to build their own HTPCs with CableCARD™. What’s more, the next generation of CableCARD™ tuners are arriving on the market now from companies like Ceton, and coming soon from Silicondust, and the reviews thus far have been fantastic.

Enabling a Windows 7 PC for CableCARD

If you’re getting ready to take this next step with your Windows 7 PC, there is a tool called the Digital Cable Advisor that you must run for the successful integration of a CableCARD™ tuner. The Digital Cable Advisor measures system parameters such as CPU speed, RAM, graphics card support for hardware acceleration, and digital connection capabilities.

  • If the PC meets the minimum requirements, the tool enables digital cable functionality on the PC. Then, users can add a digital cable tuner with a CableCARD™, allowing them to access all of their high definition and premium cable content within Windows Media Center, but without using a set-top box.
  • If the PC does not meet the minimum requirements, the Digital Cable Advisor will indicate which components failed and make some basic recommendations for upgrading the PC to accommodate digital cable.

In Windows 7, Digital Cable Advisor can be found within Windows Media Center’s extras gallery.

If your system has met the minimum requirements, you will be notified and prompted to update the system settings. Select Update System Settings to configure the system to support a digital cable viewing experience on your PC.

Update on success

Next Steps and Additional Considerations

Now that you have enabled your PC for digital cable, you will still need to obtain a digital cable tuner, a CableCARD™ from your cable service provider, and a premium content subscription. How cable companies deal with CableCARD™ Windows Media Center PCs tends to vary greatly by provider.
