HD service provides channels with the best picture quality, as well as additional channels that are only available in HD. Get more details about HD service.
Digital television is any all-digital broadcast, which has many advantages over older broadcasting systems. HD represents the highest quality of digital television.
HD service requires an HD converter to accept the different types of signals that are transmitted with this programming. These converters look similar to standard converters and function the same way. There is no additional cost for an HD converter.
An HD converter gives you access to additional channels that are only available in HD. The standard definition channels you watch with a regular converter are still displayed in standard definition, but many of these channels have a separate HD version on a different channel number. These HD channels become available if you have an HD converter.
VCRs and DVD recorders cannot record HD programming. You can get an HD DVR from Bright House Networks to record HD programming while receiving the additional benefits of DVR service.
HDMI cables provide a High Definition connection between your HDTV and HD converter without the need for separate audio wires. HDMI has other advantages, too.
