- Description
- id RoQ is a proprietary video (and audio) container format developed for use in video games. It uses a custom codec combining vector quantization for video and a simple compression scheme for audio, designed for fast decoding on limited hardware. It was used in several id Software games such as Quake III Arena and Return to Castle Wolfenstein to play full-motion video cutscenes.
- 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.
