  • 1. End-user Network and IPTV Receiver Shuji Hirakawa IEC Technical Committee 100 (TC 100) Secretary IEC TC 100 AGS Secretary
  • 2. Between IEC and ITU-R <ul><li>ITU-R SG 6 and IEC TC 100 have implicit but very clear boundary in Broadcasting standardization </li></ul><ul><ul><li>TV Broadcasting standardization has long history near 50 years since 1960s </li></ul></ul><ul><ul><li>ITU-R SG 6 including its former SGs 10 and 11 has established good relationship with IEC </li></ul></ul><ul><ul><ul><li>Especially, receivers and professional recording equipment </li></ul></ul></ul><ul><ul><ul><li>ITU-R covers broadcasting side and IEC covers receiver side </li></ul></ul></ul>
  • 3. Digital broadcasting case <ul><li>ITU-R developed Recommendations for broadcasting systems and IEC did International Standards of receivers </li></ul><ul><li>The following table shows an example of digital broadcasting system RECs and their receivers’ International Standards </li></ul>IEC IEC ITU-R ITU-R IEC 62002-1, 2 IEC 62455 IEC 62216-1 IEC 62028 IEC 62028 To be included in IEC 62360 IEC 62360 IEC 62360 Doc. 6/374 Multimedia System H Doc. 6/374 Multimedia System C Mobile (One-Seg./DVB-H) BT.1306 System B BO.1516 System A DVB BT.1306 System C BO.1516 System D ISDB Terrestrial Satellite
  • 4. Reference Models of End-user Network <ul><li>There are several reference models for end-user network </li></ul><ul><li>ITU-T SG 9 is revising its J.190 </li></ul><ul><li>ITU-T FG IPTV is developing Home Network model for IPTV service </li></ul><ul><li>CEA/OCC is discussing Home-Network Model for IPTV service with ATIS </li></ul><ul><li>HN-WG.A is developing Node Reference Model for Home Network </li></ul><ul><li>DLNA seeks interoperability framework </li></ul>
  • 5. ITU-T J.190 Rev.1 J.190 Figure 5-1
  • 6. ITU-T J.190 Rev.1 (Cont.) Shown in Figures 5-1 and 5-2, the MediaHomeNet architectural framework introduces the concept of logical elements. There are four distinct classes of logical elements defined by the MediaHomeNet architecture framework; these are referred to as Portal Services (PS), Layer-1/2 Converters (LC), Boundary Points (BP), and End Point (EP).
  • 7. ITU-T FG IPTV/WG 5 Model <ul><li>End-user network is consist of primary domain network and secondary domain network according to the ITU-T FG IPTV Document 126. </li></ul><ul><li>An IPTV end-user device can be connected to an Access Network through the Access Gateway and Primary Domain Network, and Secondary Domain Networks in addition to RF connection to Broadcasting Service Network. </li></ul>
  • 8. CEA/OCC Model
  • 9. CEA/OCC Model
  • 10. HN-WG.A Node Reference Point A: Connection Point of IP End-User Network Point B: Connection Point of Non-IP End-User Network Point N: Connection Point between IP Wide Area Network and End-User Network Wide Area Net-work NT Access Gateway IP Equipment Non-IP Gateway Non-IP Equipment IP Home Network (Wired/Wireless) IP Home Network (Wired/Wireless) Point N Point A Point B Access Network
  • 11. DLNA Interoperability Framework <ul><li>Complete set of components to deliver user experience for sharing content </li></ul><ul><li>How media content is encoded and identified for interoperability </li></ul><ul><li>How media content is transferred </li></ul><ul><li>How media content is identified, managed, and distributed </li></ul><ul><li>How devices discover and control each other </li></ul><ul><li>How devices physically connect together and communicate </li></ul>Content Sharing Framework Networking & Connectivity (IPv4, Ethernet, 802.11) Device Discovery & Control (UPnP Device Arch) Media Management (UPnP AV) Media Transport (HTTP) Media Formats (Images, Audio, AV)
  • 12. Overlapping foreseen in a year in case of IPTV <ul><li>Unlike digital broadcasting case in ITU-R, management group members of ITU-T Focus Group on IPTV (FG IPTV) may have different historical background </li></ul><ul><ul><li>The members may come mainly from telecom operators and their system and equipment suppliers </li></ul></ul><ul><ul><li>They may have less experience of working with other international standardization bodies including IEC than ITU-R Broadcasting Group </li></ul></ul><ul><li>Formally, telecom operators were controlling their terminal devices that were distributed by themselves </li></ul><ul><ul><li>Broadcasting receivers have been in consumer domain from the beginning </li></ul></ul>
  • 13. Overlapping foreseen in a year in case of IPTV (Cont.) <ul><li>The specifications of consumer equipment like TV receiver has been standardized in IEC </li></ul><ul><li>ITU-T FG IPTV Working Group 5 is ‘ End Systems ’ including ‘ Terminal Devices ’ and ‘ Home Network ’ </li></ul><ul><ul><li>Some part of IPTV receivers may be obtained by end-users from retail market (i.e. consumer equipment.) </li></ul></ul><ul><ul><li>Some part of ‘IPTV Terminal Devices’ are just digital TV receivers. </li></ul></ul><ul><li>Because IPTV may include some part of broadcasting services, the framework of standardization should be as same as the case in ITU-R SG 6. </li></ul><ul><ul><li>Transmission side is under ITU (ITU-T) </li></ul></ul><ul><ul><li>Receiver side should be under IEC including terminal devices and home network </li></ul></ul>
  • 14. Actions Requested <ul><li>IEC General Secretary and ITU-T Director should recognize ‘overlapping foreseen in a year’ between two bodies on IPTV receivers and end-user network. </li></ul><ul><li>IEC General Secretary and ITU-T Director should develop mechanisms to resolve the following issues in addition to current liaison mechanism between ITU SG and IEC TC: </li></ul><ul><ul><li>ITU-T asks IEC to develop an International Standards under the scope of IEC, or vice versa. </li></ul></ul><ul><ul><li>To develop dual logo (IEC & ITU-T) document if necessary. </li></ul></ul><ul><ul><li>To encourage JCA IPTV and JCA Home Network to open the membership to IEC </li></ul></ul>
  • 15. IPTV is a case <ul><li>It is observed that there are three types of IPTV: </li></ul><ul><ul><li>Internet Video (Type 1) </li></ul></ul><ul><ul><li>Telco IPTV (Type 2) </li></ul></ul><ul><ul><li>TV Over Net or Web TV (Type 3) See the following pages </li></ul></ul><ul><li>The end-user devices (user premises) should receive as many television services as possible while ITU-T FG IPTV is focusing mainly on Type 2. </li></ul><ul><li>Similar situation is foreseen in End-User Network (Home Network in ITU-T) </li></ul>
  • 16. Type 1: Internet Video (TV) <ul><li>Video content that is streamed over the internet to a home PC. User has to navigate, typically via the web browser on their home PC, to a particular website, selects the desired video contents to be viewed, and wait for the video streaming to begin. </li></ul><ul><li>Typically, content is viewed on the PC display , rather than a television display, unlike traditional TV content. </li></ul><ul><li>Users usually need traditional PC navigation devices, such as a keyboard and a mouse , to interact with the application and make his/her content selection. </li></ul><ul><li>In the first presentation, it is called as ‘Internet TV.’ </li></ul><ul><ul><li>E.g., YouTube, Google Video, etc in USA, and Gyao, etc in Japan. </li></ul></ul>
  • 17. Type 2: Telco IPTV <ul><li>Video services comprising a line-up of traditional TV programs , often in metaphors familiar to traditional TV users. </li></ul><ul><li>Users typically can choose to watch a “channel” of “linear” TV content . </li></ul><ul><li>The service is very similar, and sometimes identical, to a cable or satellite TV service. </li></ul><ul><li>A set-top-box (STB) is used to provide the video signal to a TV receiver display in consumer's home. </li></ul><ul><li>In some cases, a digital TV set can be a target receiver of telco IPTV services. </li></ul><ul><li>The user typically uses a remote control to navigate, select and interact with contents. </li></ul>
  • 18. Type 3: TV Over Net or Web TV <ul><li>A new TV receiver , or an adapter box, will have an Ethernet (RJ-45) jack that is used by the TV to navigate out onto the internet to access specific websites where either live or on-demand video content can be streamed to the TV. </li></ul><ul><li>In some parts of the world, such as Japan and parts of Europe, TV receivers that previously use the internet to access non-video data (e.g., local weather, traffic conditions, sports score, etc.) are now able to access video content over the internet. </li></ul><ul><li>User uses a remote control to navigate, through the internet-enabled TV receivers, the content selection. </li></ul>
  • 19. International Standardization Activities in IEC <ul><li>End-user system comprises ‘terminal (device)’ and ‘end-user network.’ </li></ul><ul><li>International Electrotechnical Committee TC 100 (Audio, video and multimedia systems and equipment) has two Technical Areas (TAs): </li></ul><ul><ul><li>IEC TC 100/TA 1 : Terminals for audio, video and data services and content </li></ul></ul><ul><ul><li>IEC TC 100/TA 9 : Audio, video and multimedia applications for end-user network </li></ul></ul>
  • 20. IP connection within end-user network <ul><li>IEC TC 100 has developed two International Standards based on DLNA Specifications. </li></ul><ul><ul><li>IEC 62481-1 Ed.1: DLNA Home networked device interoperability guidelines - Part 1: Architecture and Protocols </li></ul></ul><ul><ul><li>IEC 62481-2 Ed.1: DLNA Home networked device interoperability guidelines - Part 2: Media Formats -> See next page </li></ul></ul><ul><li>‘ DTCP-IP’ allows end-user IP network to carry HDTV content between a TV receiver and digital recording devices under localization restriction (a measured RTT should be less than 7 milliseconds.) </li></ul><ul><ul><li>DTCP: Digital Transmission Content Protection </li></ul></ul><ul><ul><li>RTT: Round Trip Time </li></ul></ul><ul><li>An end-user device with HDTV video decoding capability has high-speed IP connectivity using an RJ-45 connector at least. -> Show an example later </li></ul>
  • 21.  
  • 22. Requirements of IPTV end-user devices <ul><li>Set Top Box or Digital Television Receiver? </li></ul><ul><li>Some of STBs may be distributed to IPTV subscribers (end-users) by Telco IPTV enterprise while some of them are obtained from retail market. </li></ul><ul><ul><li>Distributed STBs by some Telco IPTV enterprises may have ‘walled garden’ restriction for ‘linear’ TV and/or VoD services. </li></ul></ul><ul><ul><li>HDTV output of STB may be displayed on a TV receiver using HDMI. </li></ul></ul><ul><li>All digital television receivers are from retail market. </li></ul><ul><ul><li>End-users are like to connect their own property, TV receiver, to any possible source including off-air terrestrial RF channels, satellite channels, some STBs, Internet TV, Telco IPTV, WebTV, etc. </li></ul></ul><ul><ul><li>Current digital TV receiver has a lot of connecters on its back panel including HDMIs, Terrestrial Coax, Satellite Coax, IEEE-1394s, RJ-45s, etc. Show an example later. </li></ul></ul><ul><li>Remote controller and large screen display </li></ul>

  • 24. An example of digital TV receiver back panel <ul><li>It has three RJ-45 connectors: </li></ul><ul><ul><li>One for a direct connection to HGW for 4th MEDIA (Linear IPTV and VoD provider using FTTH) </li></ul></ul><ul><ul><li>One for external HDD for recording and retention </li></ul></ul><ul><ul><li>One for general purpose IP connection, for special EPG, Internet TV including ‘Actvila’ (www.actvila.jp), etc. </li></ul></ul>RJ-45 x 3: for HDD, for General Purpose, and for 4th MEDIA HDMI x 2 for 1080/60P USB for HDD
  • 25. Requirement for end-user network connectivity <ul><li>Recording capability is very important for IPTV STB and digital TV receiver. </li></ul><ul><li>DLNA provides content viewing of recording equipment (Digital Media Server) by a large screen flat panel display such as digital TV receiver (Digital Media Player). </li></ul><ul><li>Content including HDTV is transmitted over IP connection of end-user network. </li></ul><ul><li>IP connection is protected by DTCP-IP in case of Japan. </li></ul><ul><li>End-user network is existing while there are so many cases household by household. </li></ul>
