scope:

This Recommendation provides models which deliver estimates of the impact of typical IP network impairments on the quality experienced by the end user in multimedia mobile streaming and IPTV applications over transport formats such as: RTP (over UDP), MPEG2-TS (over UDP or RTP/UDP), 3GPP-PSS (over RTP).

The models are network planning tools. They are of help in selecting IP-network transmission settings such as the audio and video format, the audio and video codecs and the audio and video bitrates, under the assumption that the network is prone to packet loss.

This Recommendation targets the same services as [ITU-T P.1201] and [ITU-T P.1202]. In particular, this Recommendation covers the same coding technologies and unreliable network mechanisms such as user datagram protocol (UDP). Moreover, this Recommendation extends the HR application area to include H.265 video coding (HEVC). However, this Recommendation is limited to QoE/QoS planning, while [ITU-T P.1201] and [ITU-T P.1202] are dedicated to service monitoring and benchmarking.

The following Recommendations have also been developed for QoE/QoS planning, but for different applications:

- [ITU-T G.107]: speech (telephone band)

- [ITU-T G.107.1]: speech (wideband) - [ITU-T G.1070]: videophone

- [ITU-T G.1030]: Appendix II: web browsing

For a summary of the services, encoding and network characteristics covered by the ITU-T G.1071 model algorithms, refer to Table 1 of clause 6
