Lossless Data Streaming

A new patent by Nintendo European R&D (NERD) has been published. It uses interpolative coding/decoding to compress/decompress entropy coding tables (itself a lossless compression tech) to further the low-level efficiency of lossless compression, enabling lossless data streaming locally or through the cloud.

It isn’t immediately clear what the IRL use cases are, but I guess that the patent might be laying the groundwork for the next-gen GameShare. Instead of streaming a lossy gameplay video, visual/audio data is losslessly streamed from the host or server to the client for perfect re-rendering. Another possibility is to stream small chunks of executables and data (not the whole game) for the client to run locally.
