I want to know the answer to the following question:
What was the source of the live feeds?
All the background I'm provided with is that "All Mainland Chinese television stations (along with some stations in Hong Kong and expatriate communities) cancelled all regularly-scheduled programming, displayed their logo in grayscale, and replaced their cancelled programmes with live earthquake footage from CCTV-1 for multiple days after the quake.". Is that enough to answer the question?
Answer: yes
