Tv for mobile_platforms

  1. 1. PC-TV for Notebook Platforms Options for adding TV functions July 13, 2006
  2. 2. Platforms for adding broadcast TV function • Internal Solutions – Mini-PCI Custom design, OEM only – PCI Express Mini Card Custom design, OEM only • External Solutions – USB 2.0 USB sticks External boxes – PCMCIA Cardbus – ExpressCard ExpressCard/54 ExpressCard/34 – Network PVR (New) – SDIO cards – 1394 (Very rare) Elgato EyeTV 500 (1394 for iMac) 2 7/14/2006 TV on Mobile platforms
  3. 3. USB Sticks • USB 1.1 or 2.0 – Bus powered – Single channel Analog Digital (DVB-T, ATSC) Hybrid (DVB-T/PAL) • Advantages – Low cost – Easy to use – A great retail upgrade • Disadvantages – Easy to breakoff – Only single channel – No HW MPEG – Video Quality 3 7/14/2006 TV on Mobile platforms
  4. 4. USB Boxes • USB Boxes – External power supply – Single Channel analog – Dual Channel analog – Single Channel hybrid – Dual Channel hybrid (none in the market) • Advantages – Better noise immunity – No thermal issues – Dual channel possible – Hardware MPEG possible • Disadvantages – Bulky – Power supply required (unacceptable to OEMs) – Costs more 4 7/14/2006 TV on Mobile platforms
  5. 5. ExpressCard • Two form factors – ExpressCard/54 – ExpressCard/34 • Two interfaces – USB 2.0 – PCI Express • Solutions today only support USB 2.0 interface • Flavors of ExpressCard TV solutions: – Single channel analog – Dual Channel analog – Single channel hybrid • Advantages – Easy to upgrade – Hot pluggable • Disadvantages – Legacy notebooks don’t have Expresscard slots – No retail channel at this time 5 7/14/2006 TV on Mobile platforms
  6. 6. Mini PCI • Still the most popular option for Notebooks • Popular with Japanese OEMs • Flavors of Mini-PCI cards – Single Channel Analog – Single Channel Analog with HW MPEG – Single Channel Hybrid • Advantages – Based on legacy PCI tech. – Customize to fit OEM req. – Low cost • Disadvantages – Not for retail – Not possible with Dual Channel – Not easy to upgrade 6 7/14/2006 TV on Mobile platforms
  7. 7. PCI Express Mini Card • Meant to be a replacement of Mini-PCI addon cards • Very few in existence today • Same advantages as Mini-PCI – Half the width of mini-PCI • Same disadvantages as Mini-PCI 7 7/14/2006 TV on Mobile platforms
  8. 8. PCMCIA Cardbus • Flavors of PCMCIA cardbus TV cards – Single channel Analog – Single channel Analog with HW MPEG – Single channel hybrid • Advantages Single analog with HW MPEG – Works reasonably well with silicon tuners – Supports all Laptops – Hot Pluggable • Disadvantages – Cardbus is getting phased out hybrid – Video quality is poor in general – Runs hot after extended viewing 8 7/14/2006 TV on Mobile platforms
  9. 9. SDIO TV • Finally, TV on our PDA! • Flavors – PAL/NTSC analog – DVB-H • Truly portable TV 9 7/14/2006 TV on Mobile platforms
  10. 10. Network PVR • External Box with TV tuner, MPEG encoder and uPnP capability • Network PVR acts as a filling Station for iPOD, PSP and laptop computers • NAS devices can be supported • Streaming audio and video over wireless networks • Uses Windows Media Connect Media Server Streaming media over wireless network Notebook downloads content Network PVR/DHT Notebook with Docking station 10 7/14/2006 TV on Mobile platforms
  11. 11. A primer on TV standards • Analog TV standards (interlaced video) – NTSC (525 lines, 29.97 frames/second) – PAL and SECAM (625 lines, 25 frames/second) • Digital TV standards – ATSC, DVB-T, DVB-S, DVB-C, DVB-H, DVB-S2 – T-DMB, ISDB-T, ISDB-S Location Cable Satellite Terrestrial North America ITU-T/J.83B (QAM) DVB-S (QPSK), ATSC (8VSB) DSS (QPSK), and 8PSK/TC Europe DVB-C (QAM) DVB-S DVB-T (COFDM) (QPSK),DVB-S2 (8PSK/16QAM) China DVB-C, DTV-C DVB-S TDS-OFDM (QAM) Japan ITU-T/J.83B (QAM) ISDB-S ISDB-T 11 7/14/2006 TV on Mobile platforms
  12. 12. Terrestrial Analog TV standards Switch off of analog TV for various regions likely in 2010-2014 12 7/14/2006 TV on Mobile platforms
  13. 13. Terrestrial Digital TV standards ATSC only in US, Canada and Korea DVB-T in Europe and Asia except Japan, Korea and China 13 7/14/2006 TV on Mobile platforms
  14. 14. DVB-H Adoption map Purple indicates countries with DVB-H trials Green indicates alternative standard adoption 14 7/14/2006 TV on Mobile platforms
  15. 15. DVB-H pilots around the world 15 7/14/2006 TV on Mobile platforms
  16. 16. DVB-H: A truly mobile standard • Digital Video Broadcast for Handheld terminals • Largely in trials and early stages of launch – Crown Castle Inc and Modeo are developing cell phones with DVB-H in US • Possible to add DVB-H capability to notebooks – Avermedia will be shipping SDIO addin card – Eopstech also has a product 16 7/14/2006 TV on Mobile platforms
  17. 17. Premium content on Notebooks • Use IR Blaster to control Cable Set Top or Satellite Set Top boxes • No other way to address this problem until Vista with OCUR is launched – Only unidirectional, so, no VOD, PPV and EPG 17 7/14/2006 TV on Mobile platforms
  18. 18. Challenges for PC-TV on Notebooks • Size and thickness constraints – Form factors of silicon – Tuners • Low power requirements – Most silicon are not designed with low power in mind • Thermal dissipation issues – 2.5 Watts maximum limit • Noise issues – Hard to get good video quality • Too many different hardware options – Single channel vs dual channel, analog vs digital vs hybrid – Hardware MPEG vs Software MPEG • Various analog and digital standards – ATSC is not a mobile standard • Premium content not supported • Antenna for digital TV 18 7/14/2006 TV on Mobile platforms
  19. 19. Silicon Vendors • Philips • Conexant • ATI • NEC • TI • Micronas • Techwell • VIXS • DibCom • Intel Zarlink • Zoran 19 7/14/2006 TV on Mobile platforms
