H.324

H.324 is an ITU-T recommendation for voice, video and data transmission over regular analog phone lines. It uses a regular 33,600 bit/s modem for transmission, the H.263 codec for video encoding and G.723 for audio. It is used in the Vialta Beamer BM-80 Phone Video Station and in several other videophones.

H.324 was adapted by 3GPP to form 3G-324M.

One of the first, if not the first, desktop computer-based videoteleconferencing systems manufactured for sale was the MINX system developed by the Datapoint Corporation (who also developed ARCNet, ARCNet Plus, and was instrumental in the initial development of the desktop computer). In its early incarnations, the MINX system was relatively proprietary. However, the current versions being sold (now being sold by a spinoff from Datapoint called VUGATE) utilize the H.324 standard (as well as being capable of using H.323 and H.320).
