how to build a digital to analog tv converter

If the analog TV also includes, in addition to an antenna/cable connection, a set(s) of RCA style AV inputs (red, white, and yellow), you can connect an external DTV converter box or a cable/satellite box that has that connection option.Contact your cable service or satellite provider for more details. Even if your old analog TV is 'cable-ready,' you may now be required to rent a box from your provider that will covert digital cable signals back to analog.

However, if you have been receiving basic cable without a box using a 'cable-ready' analog TV, many services no longer provide analog TV signal output via this connection option. If you subscribe to a cable or satellite service, and the box provides an analog RF output with supporting analog signal service, you may be able to access programming.You won't get any of the increased resolutions of DTV or HDTV, and all widescreen programming will show up as letterboxed (black bars on the to top and bottom of the image) on your analog set. Placing the DTV converter box between the antenna and the TV converts incoming DTV/HDTV signals to signals compatible with any analog TV. If you receive TV programming via antenna, external DTV converter boxes are available that enable using older TVs.
