The PWS4500 live server system is one of the key elements of Sony's next-generation 4K/HD live production solution with IP technology. The PWS4500 incorporates all the functions of the PWS4400, including XAVC (both 4K and HD) and Avid DNxHD® recording capabilities, flexible I/O configurations, and HFR recording capability. In addition, the PWS4500 adds IP interfaces, file-sharing function (Share Play), and redundant power supply. Moreover, the system can be configured flexibly, using various optional accessories, allowing it to be used as a highly cost-effective plain HD production recorder with less I/Os, or as a full-featured slow replay server supporting both 4K and HD formats, and both SDI and IP interfaces, depending on users requirements. The PWS4500 system consists of four products the PWS4500 Multi Port AV Storage Unit (as a recording deck), the PWSK4403 USB Control Device (as a control panel with a jog shuttle and a fader lever), the PWS100PR1 Production Control Station (Workstation that runs production application software), and the PWS100MG1 Media Gateway Station (Workstation that transfers files). In addition, there are several option boards and software that need to be installed per users' requirements. Moreover, the associated Windows 8 PC running application software, the PWARCT1 Recording Control Software, which can trigger rec/stop/play/file transfer from a PC, adds operational flexibility to the PWS4500 so that it can be used as an easy-to-use multiport 4K/HD production recorder for a wider variety of production usages.
