In anticipation of the widespread implementation of digital broadcasting, companies are building up their digital broadcasting infrastructures, developing receivers, and coming out with new products to support the industry. The VT1200 series of compact MPEG2-TS generators is designed with the TS generation capabilities essential for operation, verification, maintenance and troubleshooting of MPEG2 equipment, as well as other leading-edge features such as support for HDTV and the ability to save user contents. The VT1200 series includes two models - the portable model (VT1200) and the rack-mountable (VT1220) - and can be used in a wide range of applications.

• Pre-installed contents and simulated motion video playback
  Patterns such as a color bar are pre-installed and can be used immediately. Simply press the Select button to access the pre-installed contents. The VT1200/VT1220 also has a simulated motion video playback feature for playing multiple frames consecutively. This is useful for detecting screen freezes. In addition, a 1 kHz tone signal is included for use in checking audio.
  
  
• Creating and saving contents
  The standard utility software can be used to create original contents, which can be transferred and saved in the VT1200/VT1220 memory. For example, you can select the color bar as the background and superimpose a station name. Next, simply click the Convert button to create a color bar with the station name on it. Both HDTV and SDTV formats are supported.
  
  

• User-friendly controls
  The VT1200/VT1220 is extremely easy to use. Simply use the Select button to select a pattern number and then press the Play button. An external control function (contact input) is included to support integration to a broadcasting system.
  

• Through output and input TS monitor function
  The VT1200/VT1220 has a through output function (works with ASI I/O only). With this function, broadcast data is output directly (through output), although you can switch to internal contents if necessary.The VT1200/VT1220 monitors in real time for TS Sync Loss, PAT errors, and other errors input to the ASI input terminal. If an error occurs, the user is alerted by LEDs on the front panel and by contact output (rear panel).
  
  
• Automatic time stamp update of the internal contents
  PTS, DTS, PCR and a Continuity Counter are updated for continuous MPEG2-TS output free of time conflicts.

  

• Simulated motion video playback function
  The VT1200/VT1220 has a simulated motion video playback function for consecutive playback of multiple frames. This makes it easy to detect locations where the screen freezes.
