All three listed technologies – MPEG, P*64, and Indeo – are video compression standards or codecs that can be used to compress video files.
– MPEG (Moving Picture Experts Group) is a working group that develops standards for digital video and audio compression and transmission (e.g., MPEG-1, MPEG-2, MPEG-4, H.264, H.265).
– P*64 (Px64 or H.261) was an early video coding standard developed by the ITU-T, designed for videoconferencing over ISDN lines at multiples of 64 kbit/s.
– Indeo was a family of video codecs developed by Intel, popular in the early to mid-1990s, used for video playback on personal computers.
Video compression is essential for reducing the storage space and bandwidth required for transmitting digital video. Different codecs and standards employ various algorithms (like spatial and temporal redundancy reduction) to achieve compression, often trading off file size/bandwidth with video quality.
