? About receivers

Telus' current devices are here: https://www.telus.com/en/tv/optik/4k-pvr-and-wireless-digital-box

The red, white and yellow inputs are for SD not HD. The old Cisco set top boxes have those outputs but the boxes are very old (7+ years) and I doubt if Telus even has any left. If using a current set top box and mini-DIN isn't an option, you'd need an adapter to convert HDMI to composite or whatever input your TV has.

How old of a TV are you trying to use? Nearly every TV made in the last 10-15 years should have HDMI on it if not component video on the older ones. (red, green, blue, white, yellow)
