In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel.
Here are some tips for boosting a digital TV signal : Move the antenna to new location or height, if you’re using an indoor antenna. Re-aim the antenna, if you’re using an outdoor antenna. Watch the signal strength meter on the digital -to-analog converter box or television as you move or aim the antenna.
Subchannels are extra broadcast signals that overlap the main signal. Whereas regular channels are marked by 1, 2, 3, etc.; subchannels are marked by decimal points . For example, if your local NBC station is on channel 3; its corresponding subchannels will be 3.2, 3.3, and so on.
To add additional digital channels : Press the Menu button on your TV remote. Select Setup in the Menu. Cursor down to Installation, then cursor right, then select channels and Autoprogram. Then select Weak channel Installation. Next, cursor right to Search and press the OK button on the remote.
