The service, which can be accessed for free by all of Sky Digital's 7.4m subscribers, will feature more video content and original editorial, according to the broadcaster.
The relaunch is an attempt by the broadcaster to improve the digital platform's usability and visual appeal.
Ian Shepherd, managing director of Sky Interactive, said: "With the launch of the new channel, Sky aims to re-assert its creative leadership in interactive television and drive increased usage and frequency among our existing customer base."
The most prominent changes will include the addition of a video-based front page with a schedule of short programmes, as well as the introduction of a contents page.
Sky says that Sky Active already has a reach of 1m users, and it is expected that the first results of Sky's 20,000-strong user panel research, expected in the new year, will offer more insight into how viewers interactive with their TVs.
The news from Sky came in the same week that Barb, the TV industry's audience measurement standard, said that it has been taking steps on building its interactive TV measurement capabilities.
Tony Wearn, research director at Barb, told a conference in Berlin that Barb is investigating which techniques have the best potential for the future.
To date, the company measures interactivity via only Sky Digital and wants to extend its detection method to include other platforms. Technical issues are inhibiting the extension of its detection methods.
