enea® H324m-BRICKS 1
Multimedia session control and transfer protocols stack for 3G video
The ITU-T H.324 recommendation was initially issued to specify a suite of standards for sharing video, voice and data simultaneously over modem connections on PSTN (Public Switched Telephone Network). It defines a control protocol (H.245) and multiplexing mechanism (H.223) as well as audio and video codecs used for real- time multimedia streaming over an established switchedcircuit connection.
