  1. Video QoE and StandardsSales Training 05-Nov-2007

  2. What is Changing? • Current standards focus on: • QoS, not QoE • Static requirements, not dynamic measurement • Systems not relevant for IP video (e.g. J.144) • Urgent need for standardized QoE tools for IP video applications • QoS not enough • Pressure to deploy QoE solutions now

  3. Breaking Down QoE Standards • Standard MOS • People know what MOS = 4 means • MOS prediction that is reliable • Predicted MOS matches viewer experience • Evaluation using large database andstandardized subjective experiments • MOS prediction that is reproducible • Standard algorithm to compute MOS • Detailed specification (equations, parameters, etc.) • No need for protocol interoperability or network interfacing as with other standards

  4. Relevant Groups • Video Quality Experts Group (VQEG) • ITU-T Study Group 9 • ITU-T Study Group 12 • ATIS IPTV Interoperability Forum (IIF) • Video Services Forum (VSF) • SCTE • IPTV Focus Group (ITU-T) • DSL Forum • Open IPTV Forum • SMPTE • CableLabs • IETF Focus onQoE modelevaluation (key groups) Focus on interoperability and requirements

  5. Summary for Service Provider • QoE monitoring solutions critical for video service success • QoS not enough, pressure to deploy QoE solutions now • Full standards to be expected by 2009-2010 • Activities in various groups accelerate & converge • Vendors align systems with standards in 2009-2010 • QoE standards do not involve interoperability between vendors • No protocol or network interfacing issues • Standardizes measurements only • Now safe to deploy pre-standard solutions • What to do in the meantime? • Provide input to standards groups • Use QoE solution that already works well today (providing reliable, reproducible video MOS) • Use QoE vendor active in key standards groups • Deploy solutions flexible to align to standards in future

  8. VQEG (Ctd). HDTV test (content-based) Model submission: 4Q/2008, Recommendation: 2009-2010 Key proponents: NTIA, NEC, Yonsei, NTT, KDDI, Opticom, Nortel Hybrid/bitstream test (just launched) Model submission: 4Q/2008, Recommendation: 2009-2010 Proponents: Psytechnics, KDDI, BT, NTT, NEC, Yonsei Univ., SwissQual, Opticom, Telchemy, Tektronix, NTIA, FT, DT, Witbe, QualiDeo, Ghent Univ., Toyama Univ.

  9. ITU-T SG12 Performance and quality of service Symmetricom will contribute to the P.NAMS (Non-intrusive parametric model for assessment of multimedia streaming) Video + audio Inputs: Packet info (loss rate/pattern, jitter, RTP/UDP/TCP header) Codec info Client info (buffering, decoder) Excludes payload information Core model + packet parameter extraction model G.OMVS (“Opinion model for video streaming”) Symmetricom will contribute to the G.OMVS Symmetricom engaged with NTT to establish a common interest working group.

  10. VSF Interoperability, quality metrics Artel, AT&T, Dimetis, Evertz, Fox, Harmonic, Harris, Ineoquest, Level 3, Media Links, Net Insight, Spirent, Tandberg, Verizon, VideoClarity Test and Measurements Activity Group Completed work in 4Q/2006 “Recommended Video over IP Metrics”, Dec. 2006 Symmetricom started the process for establishing a QoE group at VSF meeting in Oct. 2007 Sponsored by at&t Proposal to VSF board members complete.

  11. ATIS IIF QoSM Task Force Telchemy, Tektronix, Telcordia, Verizon, AT&T, BT, Nortel, Ericsson, Motorola, Qwest, JDSU, Cisco “QoE Model for Video, Audio, Multimedia and Transactions” (WT-005) Plans to incorporate “Quality of Experience Requirements for IPTV” (FG-IPTV, DSL-Forum) Symmetricom will be active participant and will support synchronization of ATIS efforts with VSF.

  12. SCTE HMS Hybrid Management Sub-layer (HMS) Committee Management and monitoring interfaces for broadband technologies. Cable MSO’s, vendors of network components, and expert industry consultants. Quarterly meetings. 1st proposal to be provided in January 2008. Symmetricom sponsored by Time Warner.
