Search and Scan automatically updates all of the programs on TV4PC's program listings and updates the entire Channel list. To perform a Search and Scan:
Frequency is the original channel frequency. If you do not wish to use the default value, consult your service provider.
"Carrier" is short for carrier frequency spacing. In terrestrial broadcasting, the original channel frequency carrying the selected information is split into multiple carriers, typically more than a thousand different carrier frequencies, each carrying small parts of the original channel's information. These carriers have a precisely chosen frequency spacing between each carrier known as the carrier frequency spacing. Use the default value or consult your service provider.
In terrestrial broadcasting, multiple carriers transmit the ones and zeroes of the digital signal as radiation called modulation symbols. Each symbol is transmitted as an active symbol transmission period followed by a short interval of rest time called the guard interval. Use the default value or consult your service provider.
After Search and Scan is clicked, the Scanning Status logs PIDs (Program ID codes), NIT (network information table) updates, PAT (program association table) updates, PMT (program management table) updates, and CAT (conditional access table) updates. The Scan Progress bar displays the progress of the entire scan. The Channel Progress bar displays the progress of the channel currently being scanned.
