Options 1S and 2S are VM700T, VMTB and VMUPG upgrade options that add a state-of-the-art serial digital video acquisition and analyzer module to a VM700T, Turbo version VM700A or standard VM700A video measurement set, providing the capability to display, capture and analyze the 270 and 360 Mbit 525 line and 625 line serial component and 143 Mbit 525 line serial composite digital video signal with unprecedented ease and accuracy. Now, for the first time, comprehensive analysis of analog video signals and serial digital video signals is possible in a single package that is the recognized leader in automatic video measurement sets worldwide. The features built into the VM700T/A Series SDI analyzer module are the result of years of experience with professional television organizations and in the designing and manufacture of advanced waveform/vector monitors and automatic analyzers for the serial digital video operating environment.
The VM700T/A Serial Digital Video measurement option benefits from the proven display technology and user interface that won a technical Emmy for excellence. All SDI (Serial Digital Interface) measurement functionality was designed with the highest degree of automation possible. The seasoned professional video equipment manufacturer to the first time SDI design engineer will find the VM700T/A SDI analyzer option innovative, accurate, fast and above all easy to use.
The VM700T/A Serial Digital Video Analyzer module installs directly into a VM700T or Turbo version VM700A. I/O connections are accessible on the instrument rear panel and include two SDI inputs, a re-clocked SDI output (switches with the active SDI input), an AES digital audio input, a Longitudinal Time Code input for time stamping logged error files and a loopthrough analog blackburst input for timing reference. SDI measurement applications can be selected through the instrument front panel, touch panel interface or RS-232-C or GPIB remote control drivers. Simple to complex SDI measurement functions can be created directly from the VM700T touch panel interface. Functions can be enabled manually, automatically using the system's internal clock or via remote control. Users who need to create and distribute VM700T SDI measurement functions to additional VM700Ts will appreciate the FTP interface that allows file transfers.
SMPTE 305M specifies a Serial Data Transport Stream that can be used to transport packetized data within a studio/production center environment. The data packets and synchronizing signals are compatible with ANSI/SMPTE 259M and can therefore pass through existing plant routing equipment. The growing use of SDTI to transfer digital video at faster-than-real-time rates with none of the compression artifacts found in MPEG provides tremendous potential to post/production applications. The VM700T Ancillary Data Analyzer application can automatically detect the presence of the SDTI signal as well as decode the SDTI Header data information for quick proofs of the SDTI transport layer. Line number, line number CRC, code and AAI, Destination address, Source address, Block type, CRC flag, Data extension flag, Reserved data and Header CRC are all decoded and clearly displayed.
The Interchannel Timing application is designed to quickly measure time delay between two SDI sources or between one SDI source and the analog black-burst reference input. Timing measurements are made in real-time and in-service without special test signals. An easy to read auto-scaling display indicates time delay in time or video frames.
