I want to know the answer to the following question:
How many HD channels did the Freeview HD service contain as of December 2013?
All the background I'm provided with is that "The Freeview HD service currently contains 10 HD channels (as of December 2013[update]) and was rolled out region by region across the UK in accordance with the digital switchover process, finally being completed in October 2012.". Is that enough to answer the question?
Answer: yes
