Using IEEE1394 interface and cable can transport high-resolution and high-quality video stream. High quality video stream But IEEE1394 cable can’t use over than 4.5 meters.About DV format(2/2): About DV format(2/2) IP (20) UDP (8) RTP DV(80byte) DV(80byte) ・・・ Using the software can be sent anywhere using the Internet The DV data sent over the Internet using RTP payload (RFC3189) . DV/RTP packet formatSoftware Introducing (DVTS,1/11): Software Introducing (DVTS,1/11) ・DVTS(Digital Video Transport System) ©WIDE project(*1) (*1) WIDE Project Internet study project inaugurated in 1988 in Japan and led by Professor Jun Murai Environmental Information, Keio University.http://www.wide.ad.jp/ ・Currently DVTS works Free BSD, Linux, MacOSX and Windows. ・This presentation talks about Windows version DVTS.Software Introducing (DVTS,2/11): Software Introducing (DVTS,2/11) System requirement Equipment: DV camera, PC equipped IEEE1394 interface, IEEE1394 cable. In the highest quality of communication, the system consumes over 35Mbps as network bandwidth.Software Introducing (DVTS,3/11): Software Introducing (DVTS,3/11) Access http://www.sfc.wide.ad.jp/DVTS and get the DVTS. And install DVTS in your PC, after that created the icon. Click this icon to start DVTS! DVTS is free software.Software Introducing (DVTS,4/11): Software Introducing (DVTS,4/11) Click this icon, the window is up. From now, give a description of each menu and each function.Software Introducing (DVTS,5/11): Software Introducing (DVTS,5/11) Input destination IP address. Send DV stream When you select Start sending menu, setting window is up. If peer use different from default UDP port, you input suited port number. If your PC or peer’s PC can’t process full frame, you set this value to adopt. This value decides to discard level. After set up, click OK bottom to start sending.Software Introducing (DVTS,6/11): Software Introducing (DVTS,6/11) Check the Preview, you can see the your sending stream in your display.Software Introducing (DVTS,7/11): Software Introducing (DVTS,7/11) This buttons control receiving stream. Because of instability of treatment of control receiving, you may fail to receiving. Then you check your network state that whether receiving packets or not. If packets are coming, you will try again and again. After that you maybe get stream. Receive DV streamSoftware Introducing (DVTS,8/11): Software Introducing (DVTS,8/11) You can use multicast for receiving. Input multicast group address and start receiving If you want to use different from default UDP port, setting this value.Software Introducing (DVTS,9/11): Software Introducing (DVTS,9/11) You can set decode quality to adopt your PC’s performance and network state. If the PC performance is less, you can’t get high quality view smoothly. Software Introducing (DVTS,10/11): Software Introducing (DVTS,10/11) This option is setting view window size on your display.Software Introducing (DVTS,11/11): Software Introducing (DVTS,11/11) If you concern packet loss rate, click this.Software Introducing (DVcommXP,1/7): Software Introducing (DVcommXP,1/7) DVCommXP ©Fatware,Inc. DVCommXP is commercial software by Fatware, Inc. To access http://www.fatware.jp and download trial version or get software license. But now, this site supported language is Japanese only. DVCommXP requires same equipment about DVTS but it works WindowsXP only.Software Introducing (DVcommXP,2/7): Software Introducing (DVcommXP,2/7) System requirement of DVcommXP OS : Windows(r)XP Professional or Windows(r)XP Home Edition CPU and Memory : One-way(DV input or output only): CPU PentiumⅢ 500MHz or more. Memory:128MB or more. Two-way(DV input and display a PC monitor) CPU PentiumⅢ 1.8GHz or more. Memory:256MB or more. Bandwidth : 30Mbps or more. Software Introducing (DVcommXP,3/7): Software Introducing (DVcommXP,3/7) File(F) Sending(S) Receiving(R) View(V) Help(H) This is the DVcommXP window.Software Introducing (DVcommXP,4/7): Software Introducing (DVcommXP,4/7) Send DV stream Input destination address. Select IP version. DVcommXP has DVTS compatibility. If peer uses DVTS, select DVTS. Select UDP port.Software Introducing (DVcommXP,5/7): Software Introducing (DVcommXP,5/7) Select IP version. Select UDP port. Display setting. DVcommXP can output DV stream by IEEE1394. Receive DV streamSoftware Introducing (DVcommXP,6/7): Software Introducing (DVcommXP,6/7) Multicast receiving Input Multicast address. Select network interface.Software Introducing (DVcommXP,7/7): Software Introducing (DVcommXP,7/7) Setting display size. This is packet loss rate window. DVcommXP can see peer’s packet loss rate using RTCP.Introducing Comet DVIP(1/10): Introducing Comet DVIP(1/10) Comet DVIP ©Comet Project Comet DVIP realizes digital video transmission at the real time on the Internet used intelligent NIC. Intelligent NIC can process sending and receiving DV stream in hardware process. Comet (Communication Enterprising Technology) Project at Fujitsu Lab. http://www.pds-flab.rwcp.or.jp/index.htmlIntroducing Comet DVIP(2/10): Introducing Comet DVIP(2/10) This is the Comet DVIP hardware. This is the intelligence NICIntroducing Comet DVIP(3/10): Introducing Comet DVIP(3/10) IEEE1394 ×2 100Base-TX Comet DVIP’s NIC has two IEEE1394 interfaces. One connects DV camera and another one outputs DV stream. It can select automatically input and output interfaces. This interface is not controlled by OS.Introducing Comet DVIP(4/10): Introducing Comet DVIP(4/10) Comet DVIP has different property from before introduced two softwares. Because of intelligence NIC, Comet DVIP doesn’t require high-spec CPU and OS. It can send and receive one PC equipped intelligence NIC. The system has dedicated hardware and software. Introducing Comet DVIP(5/10): Introducing Comet DVIP(5/10) This is Comet DVIP software icon. Click this icon. It asks you to be going to load firmware, it takes some time (Y/N). Click “Yes”. Some time later, Comet DVIP control window is up.Introducing Comet DVIP(6/10): Introducing Comet DVIP(6/10) This is Comet DVIP control window. Configurations. Control NIC. Comet DVIP control software works Linux, FreeBSD and Windows Me/2000/XP.Introducing Comet DVIP(7/10): Introducing Comet DVIP(7/10) Select IP version and transmission mode. Input destination IP address (target) and your IP address (self). Because of Comet DVIP network is not controlled by Windows, you need to input your IP address and Gateway.Introducing Comet DVIP(8/10): Introducing Comet DVIP(8/10) ③ ② ① ③ You need to click Initialize bottom and 1394 reset bottom to start sending or receiving DV stream. After that, click send bottom or receive bottom.Introducing Comet DVIP(9/10): Introducing Comet DVIP(9/10) Comet DVIP output is DV format, you prepare the display equipped DV interface or connect to IEEE1394 “windows” interface. Most of the monitor has NTSC interface only, then you need to setting DV to NTSC converter.Introducing Comet DVIP(10/10): Introducing Comet DVIP(10/10) You connect Comet DVIP’s IEEE1394 interface and “windows” IEEE1394 interface to see the received DV stream in your display. After connected, you can see the stream on your display using DV capture tool.Comparison(1/2): Comparison(1/2) Comparison of functions.Comparison(2/2): Comparison(2/2) Comparison of functions.Slide37: DVcommXP To sale for it outside of Japan needs to reserch violations of intellectual property rights. Fatware, Inc. sales DVcommXP in Japan only because of they don't research that things. If any agency which wants to sale DVcommXP outside of Japan is coming up. And it researches violations of intellectual property rights and the problem will become clear. They will discussion about to sale overseas. DVTS demonstration machine send CPU:AMD AthlonXP 1.2GHZ Memory:256MB receive CPU:Pentium3 Mobile CPU 750MHz Memory:256MB Sending machine can two-way connection. I’ve test before.
