  • Page 4: A: Introduction

    INTRODUCTION The SCOPIA XT1000 is a High Definition (HD) videoconferencing system with a maximum picture resolution of 1080p i.e.1920 x 1080 pixels at 30 fps (frames per second). The optional Sony 60 fps camera extends the frame rate to 60 fps but with a consequent reduction in resolution to 720p or 1280 x 720 pixels.

  • Page 5: B: Setup Procedure

    SETUP PROCEDURE Setting up the SCOPIA XT1000 system was straightforward. The CODEC unit may be mounted on a shelf in an under-monitor cabinet or positioned vertically adjacent to the monitor using the stand supplied. A rack mounting kit is not available. The HD camera may be positioned either on top or below a picture monitor.

  • Page 10 1080p Several audio formats are supported by the SCOPIA XT1000. Radvision has implemented the ITU standard G.719, giving 20Hz-20KHz analogue audio with low latency/delay. The 3-way microphone pod uses beam forming technology to improve pickup from the presenters while minimising background noise. In larger installations an additional microphone pod may be daisychain cabled to the main microphone.

  • Page 11: D: System Operation

    D: SYSTEM OPERATION The system may be operated locally either from the remote control or via a room control system. As the system does not support RS.232 control this requires an IP link using the API command protocol. Control is also available via the optional SCOPIA iPad application.
  • Page 12 Remote Control The system may also be remotely configured and controlled via a password protected web browser from a network connected PC. Diagnostic and call statistics are usefully available from this web interface but unfortunately web snapshots of transmitted and received images are not.

  • Page 14 system automatically goes into screensaver mode after a selectable period of time; it can also be put into standby mode via the remote control. An incoming call or button press on the remote control will return the system to active mode. Optional MCU An optional nine site MCU supports up to eight remote sites and the host SCOPIA XT1000 MCU CODEC.

The received audio level was measured as peaking to -4dBm.

    Mobility The SCOPIA XT1000 is designed to be installed adjacent to a picture monitor but is also lightweight and portable so can be moved easily. To establish a connection, each new location will need the local IP address to be re-entered into the...

  • Page 20: Appendix 2 Detailed Video Tests

    Appendix 2 Detailed Video Tests During all video tests the audio protocol negotiated was G.719. When the system was forced to H.263 video protocol, image material connected to the DVI input was restricted to 8fps at XGA resolution. This has a serious impact on many of the rating scores as motion and lip synchronisation were significantly affected by this reduction in frame rate.
