Technical data
  • Low cost upgrade for MPEG IMX VTRs
  • The BKMW-E3000 can be quickly and easily installed into MPEG IMX VTRs. Users who already have MPEG IMX VTRs in operation, can upgrade to e-VTR functionality at a fraction of the cost of the VTR itself.
  • Lossless transfer of MPEG-2 data via Gigabit Ethernet networks
  • The Material Exchange Format (MXF) lets you transfer MPEG IMX video data between devices without any degradation of picture quality. This MPEG IMX data complies with SMPTE 356M, the D-10 bit stream standard. Uncompressed digital audio and metadata can also be exchanged across the network with no degradation to the original data.
  • Industry standard network interfaces and protocols
  • The e-VTR is equipped with an IEEE 802.3ab 1000Base-T interface which uses an RJ-45 connector. The e-VTR uses TCP/IP and File Transfer Protocol (FTP) for exchange of MXF files between devices. FTP is also used to control the e-VTR via the network.
  • Two-way transfer of MXF files
  • The e-VTR can output MXF files from any standard definition Betacam-family cassette. In addition, MXF files carrying D-10 MPEG IMX data can be input to the e-VTR from the network. The D-10 data is "unwrapped" from the file and recorded onto an MPEG IMX cassette. A large MPEG IMX cassette can record up to 220 minutes of material when operating in 625/50 mode.
  • Supplied application software for simple e-VTR control
  • A software application is provided for simple control of multiple
  • E-VTRs on the network. This windows-based application allows files to be selected and then dragged and dropped from one e-VTR to another. The application provides tools for the creation, naming, browsing and deletion of files.
  • Low resolution browsing for shot selection and approval
  • Remote agencies and production centres frequently need to view content for approval, or incorporation into programmes or commercials. The e-VTR can output low-resolution browse quality video and audio from any standard definition Betacam-family cassette. This allows editorial decisions to be made while keeping network traffic low. After a specific shot has been identified, a full quality 50Mb/s version can be delivered via the network. The format of the low resolution output is based upon MPEG-4 and is the same as that used in the XDCAM system.
  • Internal web server for browsing via a PC
  • The e-VTR generates HTML pages from an internal web server. A standard Windows-based browser can view these pages to browse machine set-up menus and video/audio file attributes.
  • Tele-File system for automatic location of files on tape
  • For fast access to individual files, the e-VTR must know their precise location on tape. The e-VTR uses the Tele-File system to achieve this. Tele-File cassette labels contain a memory chip onto which data can be written and subsequently read. This read/write process is achieved using a non-contact reader/writer that is built into the cassette compartment of each MPEG IMX VTR. During the recording of an incoming file, the e-VTR writes its IN and OUT point to the Tele-File label on the MPEG IMX cassette.
  • If this tape is subsequently used in another e-VTR, the e-VTR reads the Tele-File label and immediately knows the IN and OUT point of every file on the cassette.
  • Tele-File labels can be purchased in batches of 100, and can be attached to any Betacam-family cassette.
  • Automatic buffering of data to and from the network
  • Video data from an MPEG IMX cassette is read from tape at a constant data rate of 50Mb/s. But the available bandwidth on a Gigabit Ethernet network can frequently be much lower than this. The e-VTR has intelligent - and automatic - buffering built-in. An internal solid-state buffer, combined with intelligent control of the tape transport ensures that the 50Mb/s data is correctly transferred across the network even when data traffic on the network is high.
  • 525/625 switchable for international operations
  • Material can be recorded and replayed by the e-VTR in either 525/60 or 625/50, and your 525 and 625 Betacam, Betacam SP, Betacam SX and Digital Betacam tapes can also be replayed.
  • Metadata enabled
  • The use of metadata is set to revolutionise the generation, storage and management of programme content. The e-VTR has been designed to operate in the broadcast systems of today and tomorrow, and can receive, record and replay metadata contained within the MXF file.
