Digital Technologies in the Home

Digital Technologies in the Home
2
Access to the home Issues

• Home networking, with end-to-end QoS, must
  accommodate connection to different broadband
  access technologies DSL, FTTH, cable, wireless,
  PLC.
• Standards are needed for common remote management
  of customer premises equipment encourage ITU-T
  adoption of DSL Forum TR-069.

3
Access to the home Issues

• Standards are needed to define a common interface
  above layer 2, based on Ethernet, between the
  home and the network for all types of access
  technology.
• Common standards are needed for home networking
  and co-existence that span in-home audio, video,
  PC, residential device control, and access to the
  home

4
Wireless

• Limitations of Bluetooth e.g. power consumption
• Coexistence of various systems
• Ageing population brings increasing needs for
  patient monitoring systems

5
Wireless multimedia home applications

• Technology Issue
• Aggressive demands for broadband wireless
  transmissions
• - 20 Mbps 100 Mbps 2.3 G/bps
• Regulation/Standardization Issue
• Many industry standards and industry alliances
• Coexistence of various standards
• Roles of standards bodies such as IEEE versus
  industry alliances developing de facto standards

6
Content Management Summary

• Management of multi-vendor equipment, especially
  in the last hop, remains a challenge
• Residential Gateway is a barrier
• Services and applications are ever-increasing
• Examples Recommendation Service, Podcasting,
  Sharing and editing of content
• End to End Solutions required
• Regardless of format, content, time or place
• Formal standardization processes need to respond
  to the proliferation of de facto and proprietary
  specifications
• Better collaboration is required between the two
• There wont be a single DRM solution
• Interoperability is a requirement for all
  content owners, service providers/distributors,
  consumers

Wireless multimedia home applications

• Digital Rights Management (DRM)/Content
  Protection
• From standardization to implementation of new
  technology, it is required to develop DRM
  mechanisms so that the content industry can
  protect the rights of content producers while
  embracing new technologies and distribution
  methods
• Spectrum allocation
• Need new frequency band (licensed or unlicensed)
  to facilitate new technology for achieving G/bps
  wireless communications for e.g. HDMI (High
  Definition Multimedia Interface)
• Interference management
• Both intra-house and inter-house interference

8
Management of equipment in the home

• Remote device management (RDM) system for DSL CPM
• Reduce installation and maintenance cost
  dramatically using RDM system, which makes use of
  HTTP, based on DSL Forum TR-069
• Home networking systems for ECHONET and KONNEX,
  respectively
• ECHONET consortium carried out the
  interoperability with multi-vender appliances
  through exhibitions and plug-fest. More than 3
  million units of ECHONET compliant appliances
  have been shipped into the market
• In the Netherlands, about 3 000 new
  houses/apartments are equipped with KONNEX
  infrastructure based on EN50090 in 2005
• Digital TV and Home Network
• DTV makes use of the output from the
  consortia/fora such as DLNA, UPnP, HDMI, etc.
• HDTV contents are transmitted over TCP/IP
  connection within a household

Best Practices Highlights

• Define and use open, established consensus
  (pre-consensus) standards
• Standards provide critical interoperability
• Multivendor/multinational participation is
  important (dont forget users)
• Networking/liaison of manufacturers with
  standards developers important in reaching
  consensus

10
Best Practices Highlights

• Other facets
• Help is needed in implementing standards into
  products
• New technologies and associated standards change
  and products/applications must keep up and
  improve how to implement them
• Certification of products/applications in meeting
  standards is being considered and already
  underway
• Consumers/users acceptance is critical on
  acceptance of products/applications in meeting
  acceptable standards
• Summary
• Standards play critical role
• Standards development need input from all to get
  acceptance
• The job is not done.

Standardizers review

• Continue periodically ITU JCA on Home
  Networking
• Taxonomy
• Management Inside Home
• Participants gt Proactive
• Role of standardizers and consortia
