  • 19. Video is very Susceptible to Loss   Single packet loss may result in an impairment (unlike voice)   Loss of different packet types result in different types of visual impairment   QoE is measured subjectively, eyes Slice error of the viewer   General definition for QoE: Impairments/time Mean Time Between the Artefacts   Common industry benchmark Pixelisation MTBA = 2 hrs or greater No more than 1 error in a 2 hour movie   Other metrics such as number of support calls may also be important Ghosting Presentation_ID © 2007 Cisco Systems, Inc.

  • 20. MPEG: Impact of packet loss   Impairment depends on which MPEG frames lost I-frame loss will result in a visual impairment Limiting loss to a single I-frame in the worst case will limit the level of impairment Detailed paper at http://www.employees.org/~jevans/videopaper/videopaper.html Presentation_ID © 2007 Cisco Systems, Inc.
