Ofcom said that its initial assessment of pay TV was that it had "delivered significant benefits to consumers", however, "there are some warning signs, such as areas where consumer choice may be limited".
The regulator is assessing the UK pay-TV market as part of an investigation into the industry, sparked by a complaint against leading pay-operator BSkyB, from rival companies within the market including BT and Virgin Media.
Ofcom said that it had concerns over whether companies had an incentive to make their premium content, such as sports and films, available to others and whether businesses were able to compete effectively when buying premium content.
