Mairead Philpott's appeal at Nottingham Crown Court is the first to be televised outside of London.
The law was changed to allow cameras into the Court of Appeal last month, and today's case is set to be the most high-profile to be broadcast so far.
Philpott is appealing a jail term of 17 years for the manslaughter of her children in a house fire in Derby last year.
