- Description
 - AVCHD (Advanced Video Coding High Definition) is a file format designed for recording and playing back high definition video. It is commonly used in digital camcorders and cameras for capturing HD footage. AVCHD leverages the MPEG-4 AVC/H.264 video compression codec, which efficiently reduces file sizes while preserving high-quality video resolution, and supports both Dolby AC-3 and linear PCM audio codecs for high-quality sound.
 - 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.
