I want to know the answer to the following question:
On its standard definition broadcast, what format does TCM use to preserve the original aspect ratio?
All the background I'm provided with is that "Turner Classic Movies presents many of its features in their original aspect ratio (widescreen or full screen) whenever possible – widescreen films broadcast on TCM are letterboxed on the network's standard definition feed.". Is that enough to answer the question?
Answer: yes
