WiB (digital terrestrial television) is a way to watch TV without using cables. It's like regular TV, except it looks clearer and has more channels. To watch WiB, you need special equipment like an antenna and a digital receiver. The antenna is a small device that you can usually put on your roof. The digital receiver is a box that you connect to your TV. Once you've set up the equipment, you can use it to watch TV shows on any WiB-enabled channel.
