Reaching Out

This document explores the seamless integration of video and telecommunication standards, highlighting the connection between two worlds: video services and telco networks. It focuses on maintaining the strengths of both sides by adopting a standards-based approach, which recognizes the unique characteristics of video conferencing beyond mere data transmission. Key specifications such as SMPTE and ITU-R standards, along with challenges like timing and data loss, are addressed. The aim is to provide dedicated video services over telco networks while ensuring reliability and quality.

  3. Two Worlds of Standards Telco Standards Video Standards ? 270 Mbps Composite MPEG 1.5 Mbps T-1 45 Mbps DS-3 155 Mbps OC-3

  4. Network Solutions Dedicated Video Service OverlayNetworkfor Video Telco Network Video Data Telephony

  5. A Standards Based Approach Maintains the Strengths of Both Sides Standard Interface Video Telco Network And Takes Nobody ‘Hostage’

  6. Current Standards For Interface ANSI T1.802.01-1996 • Component Digital to DS-3 Interface • Proposed Extension to OC-3 Rate ITU-T H.320 • Narrowband - up to T-1 rates • Video conferencing

  7. Video Is A Unique Service • Can’t be treated merely as ‘data.’ • Timing problems • Data loss problems • Timeliness of Video • Must be there when expected • Must be complete • Can’t be ‘re-sent’ • Can’t be treated merely as ‘data.’ • Timing problems • Data loss problems • Timeliness of Video • Must be there when expected • Must be complete • Can’t be ‘re-sent’
