- Description
- CRI USM Video is a proprietary video container format developed by CRI Middleware for use in video games. It stores compressed audio and video streams, often using CRI's own codecs, and is commonly used for cutscenes and in-game video playback. It is prevalent in many console and PC games developed in Japan.
- RealPlayer created RA for audio streaming. It makes use of various audio codecs from those that deliver high-fidelity sounds to those that record low bitrate audio data. Radio stations mainly used it for online streaming, but current formats have overthrown it.
