All rights reserved. 2 Business Drivers • Compe77ve pressures • Mul7screen services • Aging RF network • Shorter STB useful life • Reduce cost of CPE • Efficient video distribu7on over PON • Flexible adver7sing • Ala carte programming Copyright 2015 – ARRIS Enterprises, Inc. All rights reserved. 8 October 2014 3 Some Network Considera6ons • DOCSIS – Serving group sizes necessary to deploy – Strategy to acquire the number of DOCSIS QAMs per service group required for the desired services – CMTS expansion – [Poten7ally] aging outside plant • FTTP – Be_er data integrity – Delivering IP video services over EPON/GPON (vs. RFOG) Copyright 2015 – ARRIS Enterprises, Inc. All rights reserved. 8 October 2014 4 Value of IP Mul6cast 5 Mul7cast vs. Unicast bandwidth savings • Viewership trends1 -‐ -‐ -‐ -‐ Over 80% of peak 7me viewership is of linear content on the big screen DVR playback cons7tutes less than 15% of peak 7me viewership VOD cons7tutes a few % 2nd-‐Screen viewership is s7ll minor 2013 ARRIS Whole Home Solu7on Copyright 2015 – ARRIS Enterprises, Inc. All rights reserved. 1 (2,386 STB, 1032 HH) Compare and Contrast: Unicast & Mul6cast in an HFC Network • Consider a typical Service Group with 250 subscriber homes, ~2.5 TVs per home, and 50% ac7ve… this yields 312 ac7ve TVs simultaneously • For pure IP Unicast… – Assume 50% of viewed content is HD @ 6 Mbps… 156*6 Mbps =936 Mbps needed for Unicast HD – Assume 50% of viewed content is SD @ 2 Mbps… 156*2 Mbps = 312 Mbps needed for Unicast SD – Total Bandwidth required if Unicast = 1.2 Gbps – ~35 DOCSIS channels required • For pure IP Mul7cast… – With ~625 TVs, sta7s7cs show that we will likely have no more than 130 unique programs being viewed at the busy hour – Assume 50% of viewed content is HD @ 6 Mbps… 65*6 Mbps = 390 Mbps needed for Mul7cast HD – Assume 50% of viewed content is SD @ 2 Mbps… 65*2 Mbps = 130 Mbps needed for Mul7cast SD – Total Bandwidth required if Mul7cast = 520 Mbps – ~15 DOCSIS channels required • Mul7cast for Linear saves ~20 DOCSIS channels (57% savings) Copyright 2015 – ARRIS Enterprises, Inc. All rights reserved. 6 Concerns with pure IP Mul6cast in an HFC Network • Slow channel change • Poten7al performance issues over DOCSIS – UDP/RTSP streaming/packet loss • No on-‐demand services • No mobile device support • No Ad inser7on/blackout management at the edge Copyright 2015 – ARRIS Enterprises, Inc. All rights reserved. 7 Mul6cast-‐Assisted ABR Addresses Unicast and Mul6cast Usage • Leverage the IPTV infrastructure – Transcoder, Packager, CDN, DRM • ABR data is delivered to the home via a combina7on of Mul7cast and Unicast – Mul7cast used as an access network bandwidth op7miza7on tool for the big screen – Unicast is used for fast channel change and mul7screen • All clients establish a standard unicast session – Client is unaware whether mul7cast or unicast are being used – Leverage a transparent proxy and a cache in an Edge Device in the home • Mul7cast is the preferred manner to fill the cache • A cache miss results in passing the request to the CDN (unicast) Copyright 2015 – ARRIS Enterprises, Inc. All rights reserved. 8 Mul6cast-‐assisted ABR Generic Architecture 9 CDN ABR Client Mul7cast Server Access Mul7cast Controller Data Gateway Home Network ABR Client • Data Gateway – Join the mul7casts and cache ABR files – Act as HTTP Proxy for the home and either respond with content from the cache or pass the request through • Mul6cast Server – Bring in ABR, wrap in mul7cast – Typically highest bit rate • Mul6cast Controller – Sta7cally manage, configure what channels are on what mul7cast – Distribute that informa7on to Mul7cast servers – Distribute that informa7on to Data Gateways Copyright 2015 – ARRIS Enterprises, Inc. All rights reserved. Mul6cast-‐assisted ABR Opera6on CDN 10 ABR Client Mul7cast Server Mul7cast Controller Access Data Gateway Home Network ABR Client 1. ABR Client makes call to CDN for asset 2. Data Gateway (proxy) has cache miss, forwards request to 3. 4. 5. 6. CDN Asset is streamed back to Data Gateway, where it is cached ABR Client hits on Data Gateway cache Data Gateway requests asset be ‘wrapped’ in mul7cast Mul7cast Controller instructs server to wrap asset in mul7cast; Data Gateway does IGMP join; con7nues to cache asset Copyright 2015 – ARRIS Enterprises, Inc.
