What is h.320?

H.320 is a standard for video conferencing that was developed by the International Telecommunication Union (ITU). It was introduced in the 1980s and has been widely used for video conferencing across different types of networks, including ISDN (Integrated Services Digital Network), LAN (Local Area Network), and WAN (Wide Area Network).

H.320 supports full-motion video with synchronized audio and has a maximum resolution of 704 x 576 pixels. It utilizes a codec to compress and decompress the video and audio data, allowing for efficient transmission over the network.

One of the advantages of H.320 is that it provides high-quality video and audio, which is essential for effective communication in business and other settings. It also supports multipoint conferencing, which allows multiple participants to communicate with each other in real-time.

However, H.320 has some limitations, including its reliance on the ISDN network, which has become less common in recent years. It also requires specialized equipment and dedicated lines, which can be costly and complex to set up. As a result, newer video conferencing standards like H.323 and SIP have become more popular.
