Broadcaster ITV is investing heavily in systems as it drives growth in channels including mobile and the web.

The company, which has reported an 13 percent annual profit rise to £462 million, on the back of sales of in-house productions to other markets, said it was determined to improve its multichannel offering.

ITV's online revenues increased by 21 percent to £34 million. "Within online, we are continuing to invest in fixing our legacy technology and in improving the quality and distribution of ITV Player," it said.

ITV Player "is now available on Android and Apple devices, Freesat and PS3, contributing to a 44 percent increase in long form views to 376 million", it said. The company is due to launch YouView, its paid on-demand service, this year, and it already has online distribution deals with Netflix, Lovefilm and Sky.

Mobile viewing of ITV content also "increased rapidly" last year, it said, representing nine percent of all video on demand viewing of ITV content in December – a figure it said was "comparable with the BBC iPlayer". The ITV Player app has been downloaded more than three million times.

The company is also focusing on improving its internal systems, with some of the changes motivated by its Manchester offices moving to the new MediaCity in Salford, also used by the BBC.

"In 2011 we launched our investment programme in technology in order to make the business fit-for-purpose," it said. "We have begun to roll out our desktop refresh, which is aimed at giving all of our people the best tools for the job, and we will continue this refresh throughout 2012."

ITV is also taking steps towards "complete digital production for all of our shows by implementing plans for tapeless content". It said that these "significant technology projects" were being implemented across the business, adding: "We are aware that they will take time to accomplish but we are confident that they will lead to great improvements to the way in which we operate."
