The redesign, which has been previewed on the PlayStation blog, will feature a simplified search feature and content listings with more detailed information about games and videos.
The store will feature more than 20,000 pieces of game-related content, including downloadable games and add-ons, the blog says. There will also be more preview videos and TV shows than before.
The improved online store will debut in the US on October 23 and will be available to those with a PlayStation 3.

Sony launched a smaller and lighter version of the PlayStation 3 at the end of September. At the beginning of this month, the Japanese company also rolled out a "PlayStation Mobile" service, which allows users to download games on their smartphones and tablet computers.
The new devices are thought to be part of Sony's strategy to try to win back customers who have moved to playing games on mobile devices and personal computers.
The company is trying to return to profit after four years of losses following the global financial crisis and a growing preference for Apple and Samusng products among consumers.
