H.324m Dcod-Bricks for 3G Video Streaming Analysis

DCOD-BRICKS™ is a portable source code implementation for non-intrusive analysis of H.324m video streams.

ITU-T H.324 recommendation was initially issued to specify a suite of standards in order to share video, voice and data simultaneously over modem connections on PSTN (Public Switched Telephone Network). It defines control protocol (H.245) and multiplexing mechanisms (H.223) as well as audio and video Codec’s to be used for real time multi media streaming over an established switched circuit
connection.

3G-324M has been derived from H.324 standards by 3GPP and 3GPP2 standardization bodies to specify multi-media communication in mobile switched circuit environments. It is used for video calls between 3G mobiles or 3G mobile and servers.

Our H324M analysis stack performs the following key features:

	Monitoring of session control protocols defined in ITU-T H.245 and ITU-T H.324.
	Generation of an event log file that includes all events related to multimedia session control.
	Generation of a message log file detailing content of all H.245 messages that have been exchanged during the session.
	Media flow extraction: for each direction media flows are stored in one 3GP file or in separate audio (AMR) and video (H.263, MPEG4) files for possible subsequent processing.

Our H.324M analysis stack is compliant with the following standards:

	ITU-T H.324 (09/2005) including procedures of Annex A (SRP/NSRP/WNSRP), Annex C for mobile communications (CCSRL and H.223 levels procedures) and K (MONA – future release),
	3GPP & 3GPP2 TS 26.111 (V6.01), TS 26.110 (V6.00), and TS 26.911 (V6.00),
	ITU-T H.245 V.11,
	ITU-T H.223 as well as its Annex A (level 1 extensions), B (level 2 extensions), C and D (level 3 extensions – future release).
