    • HDV over IP in Korea 2004.1.28. Joonbok Lee [email_address] KAIST
    • Contents
      • HDV
      • Standards for HDV over IP
      • HDV over IP Activities in Korea
        • HDVTS (KAIST)
        • VideoLAN for HDV (K-JIST)
        • HDTV Media Gateway System(ETRI)
        • Demonstration Plan
    • HDV
      • HDV Fortmat :
        • High-Definition Digital Video Recording and Playback on a DV cassette tape http://www.hdv-info.org/
      • JVC GR-HD1 Camcorder
        • 720/30p (1280x720, 30fps)
        • MPEG-2 TS
          • Element Stream Type Video: MPEG2 (ISO/IEC 13818-2)
          • Audio: MPEG1 (ISO/IEC 11172-3)
        • About 20Mbps
        • Support IEEE1394 interface.
        • Encoding Delay: about 1 sec.
    • Standards for HDV over IP
      • RFC 1889: RTP: A Transport Protocol for Real-Time Applications
      • RFC 2250: RTP Payload format for MPEG1/MPEG2 Video
        • RTP Payload contain integral number of MPEG transport packet (188byte).
        • Suggest several MPEG picture fragmentation rules.
        • RTP Header fields for MPEG2 Video
      • HDV over IP Activities in Korea
      • HDVTS (KAIST)
      • VideoLAN for HDV (K-JIST)
      • HDTV Media Gateway System (ETRI)
      • Demonstration Plan
    • HDVTS
      • 1) System Diagram
      • 2) Specification
      • Platform: Microsoft Windows XP (based on DirectShow)
      • Protocol: RTP over IP (RFC 2250)
      • Supports Unicast, Multicast, IPv4, and IPv6.
      • MPEG2 Decoder:
        • Software Decoder (Elecard’s MPEG2 Decoder, libmpeg2)
        • Plan to support hardware decoder.
      • Sender: Pentium 1GHz. 256MB RAM
      • Receiver: Pentium 2GHz. 512MB RAM (for software decoder)
      • Prototype will be completed by Feb.
      • Both binary and source code will be opened to public.
      • 3) Software Modules
      • Implement as DirectShow Module.
      • Sender: Receive MPEG2-TS stream from JVC GR-HD1 using IEEE1394 interface, and then make RTP packet.
      • Receiver: Depacketize RTP packets, and then decode and show MPEG2-TS stream.

    • VideoLAN for HDV
      • VideoLAN
        • http://www.videolan.org
        • Free Software and Open Source video streaming solution for every OS.
        • Mainly designed for high bandwidth application
        • VLS (Server) + VLC (Client)
        • Supoprt MPEG-1, MPEG-2, MPEG-4 and DivX.
        • Uses free software mpeg-2 decoder. (libmpeg2)
        • Supports IPv4, IPv6, Unicast, Multicast.
        • RTP: RFC 1889, RFC 2250
      • K-JIST modify VLS to support MPEG2 TS stream from IEEE1394.
      • Need to optimize IEEE1394 interface reading module.
      • Testing in Local Network.
      • Kiyoung Lee <kylee@netmedia.kjist.ac.kr>
    • HDTV Media Gateway System
      • HDTV Media Gateway System for multiple platforms.
      • VOD, Live contents.
      • Add live stream facility using JVC HD camcorder.
      • Developing modules for JVC HD camcorder to embedded Linux.
      • YouHyeon Jeong <yhjeong@etri.re.kr>
    • Demonstration Plan
      • 59 th IETF Meeting.
        • 2.29 ~ 3.5
        • Multicast HDV stream of some IETF Meeting sessions.
      • Buddha on the Net. (Prof. Dae Young Kim)
        • 5.26
        • Multicast HDV stream of Korean ceremony of Buddha’s birthday.
