I know ATV support up to 1080p but cannot find any info on the 1080i support. I am wondering if tvOS/ATV 4 supports playback of 1080i video and live streaming. Thanks.

Does tvOS/ATV 4 support 1080i video resolution?
Apple TV does not currently support 1080i resolutions. If you would like to request this functionality, please file a feature request at https://bugreport.apple.com/
