subchannel
Channel within channel
A subchannel is a division within a larger channel—a secondary path for communication or data transmission that operates within or alongside a primary one.
In broadcasting, subchannels are additional program streams carried on a single digital television frequency: The station runs classic movies on its subchannel.
In networking and telecommunications, subchannels partition bandwidth for separate data streams.
Online platforms use the term for nested discussion spaces within a main channel.
