Sony Patents “Remastering by Emulation,” Adding 4K, HDR, Better Textures & More Without Touching Game Code

PS4 9.00 Beta

Could Sony be readying backwards compatibility with the PS5? It seems Sony Interactive Entertainment America, which is the parent company of the PlayStation brand, has patented “remastering by emulation” over at the United States Patent Office.

Spotted byReddit user AlphaFoxWarfare, this patent sounds similar to what Microsoft has done with the Xbox One X enhanced backwards compatibility, by adding 4K resolution, HDR (high dynamic range), better textures and more but without touching the actual game code.

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.

Is this for the PS5? One can hope, right?  Just today, we also posted another Sony patent, and this one is about adding a touchscreen to a gaming controller, which could very well be for the PS5’s input method.
