Component Block Diagram - Details
The overall ideas behind this combination system are:
• The operator/ facility is utilizing the free off-air signals and wants their digital televisions to only tune to CATV channel assignments
• The operator/facility can immediately upgrade to take advantage of the signal quality improvements offered by the digital off-air (8VSB) transmission
• The operator/facility can keep using their existing analog viewing locations by converting the digital off-air (8VSB) transmission back to analog; Digital Off-Air (8VSB) Reception - Analog Viewing
• The operator/facility will also have the digital off-air (8VSB) signal transcoded to QAM for the digital televisions set in "CATV Mode" and tuning CATV channel assignments; Digital Off-Air (8VSB) Reception - Digital CATV (QAM) Viewing
