Sony could be bringing backwards compatibility to future consoles.



A newly published patent entitled 'remastering by emulation has sparked speculation it could be a possibility after it was revealed this month.

As reported by Gearnuke, the patent from Sony Interactive Entertainment America details the live remastering of textures from older titles, and placing them "on the fly" with new ones more in keeping with high resolution displays.

The patent explains: "Each asset such as a texture called for by legacy software such as a legacy computer game software has a unique identifier associated with it... The unique identifier can be rendered by imposing a hash on the asset, and then the asset stored with its identifier in a data structure.

"An artist remasters the textures for presentation on a higher resolution display than envisioned in the original software, and stores them back in the data structure with their identifiers.

"The original software is then played on the higher resolution display, with asset (such as texture) calls being intercepted, identified, and the data structure entered to retrieve the remastered asset having a matching identifier. The remastered asset is then inserted on the fly into the game presentation."

However, Eurogamer has noted that newly published patent was originally filed for in 2016, suggesting there's a possibility it's the technology the PlayStation 4 uses to run PlayStation 1 and 2 titles.
