Excellent attempt and nice PQ.
If possible please close the window that reflects on the TV and place the camera on a table so the picture does not shake.
Also it seems the screen can hold upto 10 channel names while browsing so if every list is given 5-7 secs while scrolling then you can easily display the entire list of channels within 1.5 - 2 mins and show channels in the remaining 2-3 mins (should result in similar duration and file size) so viewers get to see both the entire list of channels and the picture quality and channel content of the selected channels.
Thanks.
