Copyright © 2007 Slide 13 Which Creates Issues With Home Devices and Wiring “Islands” communicate poorly -- or not at all –No way to move baseband video and audio (e.g., DVD player output) from one room to another –DVRs can’t talk with each other –Can’t get A/V content from PC to TV screen –Need to physically move digital camera and camcorder from one place to another (PC, TV) –Weak control over lighting, no connection to HVAC Many things we wish we could do but can’t –Record movie on one DVR and play in another room (could do it if they were same brand) -- needs both media and control solution –Monitor and control lighting and HVAC from outside house –… Lacks ease of use and ease of administration –Incredible level of complexity both in trouble shooting and whenever we want to do something “a little different”
Copyright © 2007 Slide 14 Home “bandwidth budget” growing “Bandwidth budget” is total pipe size needed to accommodate all the information being sent around the home –Includes bits from all the things that people want to interconnect Just like any budget, it keeps expanding! –People want to connect more devices Not just PCs, but digital camcorders, MP3 players, PVRs, games,.. –Each device is getting richer information Digital cameras going from 6 to 8 to 10 megapixels TV going from standard definition to high definition Computer files going from data to incorporate video, special effects Consumer interest in entertainment will keep driving bandwidth both to and within the home
Copyright © 2007 Slide 15 …Creating New Requirements for Home Networks Carry high-speed data –“Fast Ethernet” sets the standard 100 Mbps Carry primary digital voice (VoIP) Carry multiple channels of high-definition video Voice and video much less tolerant than data –Need low bit error rate (BER), latency, and jitter –Isochronous very time sensitive –HD video requires high data rate: 10 to 20 Mbps per channel (more during “trick play”) Cost effective for mass consumer market –Large – preferably global – ecosystem –Multiple chip and hardware makers –Standards-based Likely to include some combination of technologies –Each serves a purpose –Should interconnect –Should not conflict/interfere with each other
Copyright © 2007 Slide 16 New Homes Are Easy Structured cabling still best choice –Coaxial cable: RG6 for analog video (and RF digital video) –Unshielded twisted pair (UTP): Category 5e or 6 for analog telephones, digital data, whole-home audio, and IP video Gigabit Ethernet runs at 1000 Mbps (1 Gbps) and getting cheaper every day Cat 6 cable has sufficient capacity for foreseeable future – will support 10 Gbps Structured media centers now widely available –Leviton and Telect on show floor Should be “no brainer” for new construction –But need to get message across to builders Expensive to retrofit in existing homes –“No New Wires” is the mantra
Copyright © 2007 Slide 17 New Technologies Arriving Many entering the market nearly simultaneously –Ethernet: 100 Mbps Gigabits per second –802.11n: next generation of Wi-Fi – over the air –MoCA: over coax –HomePNA: over coax and phone line –HomePlug AV: over power line –UPA / Opera: over power line –HD PLC: over power line –UWB: over coax, power line or the air (“Wireless USB”) All claim to be suitable for multi-channel high-definition video –Incorporate high bandwidth, QoS –Performance claims need to be verified New standards for media interoperability –DLNA and Microsoft Rally for consumer networks
Copyright © 2007 Slide 18 Networking Technology Decisions Need Analysis Not just getting digital video from ONT to digital set top boxes –Need to enable interconnection among media devices (almost everything including cellphones) including legacy devices Many Choices of Networks –Five types: new UTP; wireless; existing coax, phoneline, powerline –Multiple “flavors” of each Not “One Size Fits All” –Probably need a combination of technologies Criteria to be applied –Fit with application –Current and future data rates –Number and location of outlets –Useful life time –Standardization –Cost –Timing –…
