Programming and transmission of the Sega Channel’s monthly services started with a production team at Sega, which would put together content every month and load it onto a CD-ROM. It was then sent to TCI’s satellitestation,[12] located in Denver, Colorado.[13] From the station, the signal was transmitted via Hughes Communications’ Galaxy 7 satellite, which uploaded at 1.435 GHz and downloaded at 1.1 GHz, to the local cable providers.
