H.320
H.320 is an umbrella recommendation by the ITU-T for running Multimedia over ISDN based networks. The main protocols in this suite are H.221, H.230, H.242, audio codecs such as G.711, and video codecs such as H.261 and H.263....

This Recommendation defines the use of advanced video codecs, including H.264:
- Command and Indication
- Capability exchange signaling
- Transport (utilizes the single NAL unit mode of RFC 3984 for H.323)
- Reduced-Complexity Decoding Operation (RCDO) for H.264 Baseline Profile Bitstreams
- Negotiation of video submodes
