TDT (Terrestrial Digital Television): TDT is short for Terrestrial Digital Television. It refers to the digital broadcast of TV channels using terrestrial signals, providing better quality and more channel options compared to traditional analog signals. Call Letters: Unique identifiers assigned to each broadcast signal on TDT. They start with "TDT-" followed by a number (e.g., TDT-234). Each set of call letters represents a specific station available on Multiplex 1. Expiration Date: The date when the current license for the signal expires. If not renewed by this date, the signal will be resold to new operators. VC (Virtual Channel): The channel number displayed on the TV screen when tuning into the broadcast. VCs for Multiplex 1 range from 2 to 5. PC (Physical Channel): The actual frequency channel number used for broadcasting the signal. Multiplex 1 uses PCs 24, 25, 27, and 29. Note: Despite being sometimes called Digital Terrestrial Television, TDT is the official short form of the name. Plans are underway for a future analog shutdown to fully transition to digital broadcasting. All TDT operations and signals are hosted on scratch.mit.edu for fun and experimental broadcasting!
