@brownknuckles yes please can you send me a screenshot and I'll raise this with the right people to have this corrected. I agree this would be misleading if you were trying to cast/Airplay content as that is not supported at this time. Thanks for the flag!
It depends on the picture quality of the video you are streaming. Telus does not publish the info, but for comparison, Netflix streams at approximately the following rates:
|Resolution||Streaming Bitrate||Hourly Conversion|
|480p (720×480)||1750 kbps||~792 MB per hour|
|720p (1280×720)||3000 kbps||~1.3 GB per hour|
|1080p (1920×1080)||4300-5800 kbps||~1.9 GB to ~2.55 GB per hour|
|1440p (2560×1440)||6350 kbps||~2.8 GB per hour|
|4K (3840×2160)||8000-16000 kbps||~3.5 GB to ~7 GB per hour|
