CCTV4 (Channel 3135)' aspect ratio distorted & hardcoded directly into the stream on cable & Xfinity Stream Portal TV

I need to open an engineering ticket for a network-level broadcast signal issue.

The aspect ratio for CCTV4 (Channel 3135) is horizontally compressed and squeezed.

This issue started approximately one week ago.

I have already conclusively ruled out all local hardware, television settings, and in-home cable box issues by running a side-by-side stream isolation test:

    1. The aspect ratio distortion is hardcoded directly into the stream on the Xfinity Stream Web Portal ("My TV Stations").

    2. The official CCTV4 native broadcast on YouTube/ & CCTV websites displays perfectly in its correct aspect ratio.

Because the distortion is present on your cable feed AND web player, this is a HEADEND INGESTION or DOWNSTREAM ECODING ERROR on Xfinity's part.

The stream metadata is likely misinterpreting the channel's 16:9 feed.

Could you please submit an Inconsistent Lineup Signal Ticket to escalate this to the Regional Network Engineers so they can reset or re-flag the feed configuration? 

Thank you
