– Several companies have home A/V equipment with Ethernet ports now, more to follow – Digital media is the norm for home and professional A/V • DVD for videos • CD, SACD, DVD-Audio for audio • Digital cable, digital satellite, High Definition TV – Convergence: • It’s not just a buzzword, it’s really happening • Computers are used to play videos and music • “Consumer media servers” with hard drive recorders – Increased penetration residential broad band access IEEE 802.3 CFI Portland July 2004 10July 2004 Home Physical Infrastructure Home Physical Infrastructure • New homes are now being wired with UTP cable • According to the Consumer Electronics Association, 52% of new homes in the U.S. are constructed with structured wiring plants • ISO/IEC has just approved the standard for residential structured wiring plants (SC25/WG3) IEEE 802.3 CFI Portland July 2004 11July 2004 It’s already happeningIt’s already happening Digital Living Network Alliance (DLNA, was DHWG) is already developing higher-level protocols that use Ethernet as the physical layer – Professional audio has used several proprietary solutions for almost a decade • It’s very popular, but the solutions are proprietary (non- standard) – Professional video is looking for similar solutions – Using Ethernet will standardize the interface across computers and A/V equipment IEEE 802.3 CFI Portland July 2004 12July 2004 In SummaryIn Summary – The home networking market has already chosen Ethernet for data • The “home” part of SOHO is growing rapidly each year • There are already products on the market from several manufacturers- --and there are more to come – The home audio/video industry is now deliberating about whether to choose Ethernet – The expansion of Ethernet into audio/video will potentially create a new market segment • Tens of millions of new Ethernet ports per year – With increased broad band penetration and the completion of EFM, the home is the next Ethernet challenge for A/V apps IEEE 802.3 CFI Portland July 2004 13July 2004 A/V Home Entertainment A/V Home Entertainment RequirementsRequirements John Gildred Pioneer Alexei Beliaev Gibson Labs IEEE 802.3 CFI Portland July 2004 14July 2004 A/V Has Time Sensitive ApplicationsA/V Has Time Sensitive Applications • Multi-Room Synchronization – Audio playback synchronized across multiple rooms – Video playback synchronized across multiple rooms and maintaining lip-sync • Network Trickplay – Multiple HDTVs accessing recorded shows on a Digital Video Recorder – Each TV attempts slow/fast playback at same time • Jam Session – Multiple instruments with live effects and mixing – Turn on instruments and immediately begin playing – 500uSec max latency, zero long term jitter • Gibson Guitar experience at 100Mbps IEEE 802.3 CFI Portland July 2004 15July 2004 A/V Application Example Requirements A/V Application Example Requirements Asym. 0<100mSec*RequiredA/V Conferencing N/A<100mSec*RequiredNetwork VideoTrickplay Asym. 0500 usecRequired Jam session (live performance) Asym. 0500 usecRequired Multi-room synchronous audio playback Long term jitter Maximum latency Data/time guaranteeApplication *Round trip including application layer IEEE 802.3 CFI Portland July 2004 16July 2004 Home Network Use Case I:Home Network Use Case I: Different Audio Tracks in Each RoomDifferent Audio Tracks in Each Room Living Room Study Bedroom Dining Room Kitchen Basement Network Attached Storage or Home Media Server Digital Audio Player Digital Audio Player Speakers Speakers Speakers Digital Audio Player IEEE 802.3 CFI Portland July 2004 17July 2004 Home Audio Use Case IHome Audio Use Case I • User stores all his music files on a Network Attached Storage (Media Server) box connected via an Ethernet switch • Each room has a digital audio receiver, connected to Ethernet, which can access and play any song from the Media Server – Digital audio receivers drive local speakers over ordinary speaker wire IEEE 802.3 CFI Portland July 2004 18July 2004 Living Room Study Bedroom Dining Room Kitchen Basement Network Attached Storage Or Home Media Server Digital Audio Player Digital Audio Player Speakers Speakers Speakers Digital Audio Player Same Track in Multiple RoomsSame Track in Multiple Rooms Home Network Use Case II:Home Network Use Case II: IEEE 802.3 CFI Portland July 2004 19July 2004 Home Audio Use Case IIHome Audio Use Case II • Sometimes, the user wants one digital audio receiver to be the “master” and control what songs are played in other rooms through “slave” receivers – A single song in the whole house – A single song in selected rooms; e.g. living room, dining room, and study, but not bedroom • Simultaneous audio playing in multiple rooms requires synchronization and phase control of audio within the limits of human hearing to prevent “reverberation” throughout the house IEEE 802.3 CFI Portland July 2004 20July 2004 Time Sensitive RequirementsTime Sensitive Requirements • Precise End-Point Synchronization – Data/time synchronization must be sufficiently precise at little or no cost – Ethernet today does not provide data/time synchronization • Bounded Jitter and Latency – Bounded jitter and latency per A/V application is required • Bandwidth Allocation Guarantee – Guaranteed protection from interfering streams is required • Plus All the Existing Benefits of Ethernet – e.g. minimum packet loss IEEE 802.3 CFI Portland July 2004 21July 2004 Next Generation AV ConnectorNext Generation AV Connector Plug and Play IEEE 802.3 CFI Portland July 2004 22July 2004 Next Generation AV ConnectorNext Generation AV Connector Clean and Simple IEEE 802.3 CFI Portland July 2004 23July 2004 The Next Evolutionary StepThe Next Evolutionary Step (Missing Link with (Missing Link with PoEPoE Option)Option) 802.11e Ethernet 802.11e 1394 1394 Room #1 Room #2 Ethernet IEEE 802.3 CFI Portland July 2004 24July 2004 Ethernet is EverywhereEthernet is Everywhere Ubiquitous, except in the homeUbiquitous, except in the home • Fast • Robust • Very familiar • Affordable right now • Very wide product selection • Growing momentum in CE industry IEEE 802.3 CFI Portland July 2004 25July 2004 Next Generation AV ConnectorNext Generation AV Connector Universal Linkage IEEE 802.3 CFI Portland July 2004 26July 2004 Consumer Electronics is Consumer Electronics is Ready for EthernetReady for Ethernet IEEE 802.3 CFI Portland July 2004 27July 2004 Home Network Potential MarketHome Network Potential Market Seyoun Lim Samsung proyoun.lim@samsung.com IEEE 802.3 CFI Portland July 2004 28July 2004 The home network is at the heart of The home network is at the heart of the digital homethe digital home • Enabling home entertainment networks is key to opening up several large potential markets.
