There is an effect.
- the preset group to which the transport stream having the same transport stream name as the currently received transport stream belongs is searched and the same as the currently received transport stream. If it is determined that there is a preset group to which the transport with the transport stream name belongs, channel selection is performed according to the preset group, so the channel number with the same transport stream name is automatically set. This is advantageous in that channel selection can be performed without the user's hassle.
