Overview

The BKMW-E3000 is a network interface board for installation in an MSW-2000 series digital videocassette recorder. With this board installed, the VTR can be added to a 10/100/1000Base-T network to transfer video, audio, and metadata as MXF files. You can use MXF data received over the network to record video, audio, and metadata to cassettes. MXF (Material Exchange Format) is a file format that stores video, audio, and metadata in a single package. It enables communications between network devices such as VTRs and servers.

e-VTR Functions

A VTR with this board installed (called an e-VTR below) provides the following functions in addition to functions provided by standard MSW-2000 series VTR.

MXF file transfer and reception (file management)

MXF files containing video, audio, and metadata can be sent and received over a network (using FTP protocol).

Windows application network services

Installing e-VTR Manager, the supplied Windows application, allows FTP file transfer and monitoring of video and audio from the application.

Using the e-VTR control panel to transfer FTP/HTTP files

You can use the control panel operation of the e-VTR instead of the supplied Windows application e-VTR Manager to transfer FTP or HTTP files. If you specify IN and OUT points in advance, you can then transfer the section between the points as a file. Up to 5 servers can be registered as transfer destinations. These destination settings are saved even after the power to the VTR is turned off.

e-monitor functions

Video and audio can be monitored on a computer screen. Video is sent from the e-VTR using JPEG compression, and audio is sent using A-Law compression.

Network transmission data rate limitations

Limitations can be placed on data transmission rates for transmissions from the e-VTR to the network. This can prevent congestion and severe degradation in performance when the network is busy.

MXF Proxy AV file transfer

You can store low-resolution video, audio, and metadata as an MXF file and handle the file at a low transfer rate. Files that contain such low-resolution video and audio data are called “MXF Proxy AV files.” MXF Proxy AV files are played back using the supplied Windows application software e-VTR Manager.

Copying of timecode from the source material

Timecode (LTC) from the source tape in the transmitting VTR can be copied as is to the cassette tape in the receiving VTR. The Setup menu of the receiving VTR (ITEM-252: TCG NETWORK REGEN MODE) can be used to specify whether the timecode is regenerated or copied as is from the source tape.

Web server network services

Internet browsers such as Internet Explorer and Netscape Navigator can be used for the following operations:

•File operations

•Displaying the hours meter

•Displaying the error logger list

•SNMP (Simple Network Management Protocol) settings

•Displaying network information

•Displaying menus for network operations

Automatic acquisition of IP addresses and other network settings

Network settings for the e-VTR (IP address, subnet mask, default gateway) can be automatically acquired from a DHCP server when the VTR is turned on and the VTR set according to the information. In order to utilize this function, it is necessary to install a DHCP server or a DHCP relay agent on the same network as the e-VTR.

Network operation using a host name (DNS client function)

When connecting with external devices via network, operations can be achieved using the host names as well as the IP addresses. Specifying a server to be connected by its host name pemits the server to be easily identified.

File jump function

When the tape already contains data defined as MXF files, you can jump between neighboring files and play the files back.

Automatic creation of MXF files from tape or memory label information

MXF files can be automatically created from information in the timecode (LTC) on the tape (rec start marks, shot marks, post marks) or from information recorded on the
