This device can be used as a terrestrial digital TV tuner in any household. You can watch in high-definition quality by connecting it to your TV with an HDMI cable. This STB model is originally a device for viewing terrestrial digital TV, BS, and CS broadcasts using signals sent via cable from a CATV contract. However, you can watch terrestrial digital TV even without a CATV contract. (Currently, if you can watch terrestrial digital TV on a regular TV, you can also watch it with this device.) (BS broadcasts can be viewed with a simple setup in areas/buildings where the CATV station transmits BS signals using a transmodulation method. They cannot be viewed using signals from a parabolic antenna.) We will provide instructions on how to set it up. Accessories include the main unit, remote control, power cable, (the shape and color of the cables may differ from the images), and a super-easy setup guide. * B-CAS cards are prohibited items on Mercari and cannot be included.
