The Technology Behind the System

Zangi-developed Streaming Control Protocol (SCP) was designed to replace Realtime Transportation Protocol (RTP) as a standard for online data transmission. SCP works by reducing the size of the payload format in order to carry up to 25% more data in IP networks on the same bandwidth.

The advantages provided by SCP include low bandwidth usage, smart Internet channel for data transmission, fast and smart recovery for lost packages, Internet Channel Quality-Adaptive system and a fully codec-independent platform.
