On Tuesday, Ofcom opted against launching an investigation of YouView, which aims to upgrade the Freeview and Freesat platforms to support video on-demand and internet services.
In doing so, the media regulator rejected a number of complaints from industry stakeholders, including Virgin Media, IP Vision and Sky.
Speaking as Sky announced strong financial results for the third quarter of 2010, Darroch remained critical of YouView, but also cautiously acknowledged the huge benefits it could herald, reports The Guardian.
Around 10 million households in the UK currently receive Freeview on their main set, while early estimates suggest that the market for YouView devices could be around 7m consumers.
"We expressed our views to Ofcom - we have two broad concerns about YouView or [Project] Canvas, as it was known," said Darroch.
"[With] leading broadcasters and ISPs in a consortium there is a risk of stifling choice and there is also the inappropriate use of public money [by the BBC]."
He added: "Ofcom made its decision and we will move on. I think generally when you look at what we are doing at Sky we are broadening out our content business.
"We always look at new distribution opportunities. We will look at it [YouView], but it is too early to say what our involvement will be."
Despite opting against an investigation, Ofcom said that it will closely monitor YouView as its impact on the UK IPTV market "will not be known with any confidence for some time".
Also today, Sky confirmed that it will start rolling out Anytime+, its new internet-delivered video on-demand service, to millions of Sky+ HD homes from next week.
