EBU Digitial A/V Sync and Operational Test Pattern

EBU Digitial A/V Sync and Operational Test Pattern

The new EBU A/V sync pattern is unique to the Testor and the new PTG 5610 Test Generator. This is an adaptation of an existing 525 / 625 patterns proposed by the EBU in technical document EBU tech 3305. LYNX Technik has adapted and enhanced this pattern for use in modern multi-format (SDTV and HDTV) environments.

 

The pattern has been designed to address a number of requirements in a modern multi-format digital broadcast facility. The pattern elements are shown below.

Aside from the static video elements, there is also a dynamic element with two video motion sequences and a three level audio sequence. These sequences are used for “transmission alive” verification, audio level calibration, left and right channel ID and audio video timing (lip sync) tests.

SPG 1707 | HD / SD Sync Pulse Generator with Genlock

The SPG 1707 is a compact, versatile analog sync pulse generator with genlock providing HD / SD video sync and audio reference signals. The module provides three SD sync outputs and three HD sync outputs and a separate audio sync output that can be switched between 48 KHz Word Clock or Digital Audio Reference (DARS).  

Features

• Wide variety of HDTV Sync standards
• Simultaneous HD and SD analog sync outputs
• 3 x HD sync outputs and 3 x SD sync outputs
• Genlock with cross lock to any sync standard
• Sync only, Color bars or Black Burst for SD sync
• NTSC, PAL or PAL M/N sync outputs
• Burst phase adjustment for NTSC and PAL sync
• 48KHz Word Clock or DARS audio reference output
• Simple to use, all controls easily accessible

Description

The SPG 1707 is a compact, versatile analog sync pulse generator with genlock providing HD / SD video sync and audio reference signals. The module provides three SD sync outputs and three HD sync outputs and a separate audio sync output that can be switched between 48 KHz Word Clock or Digital Audio Reference (DARS).  
 
Flexible genlock capability allows the module to genlock to any SD or HD reference input, with full cross lock capability, even across unmatched standards.  
 
The HD tri-level sync outputs can be set to any of the available HD standards, and the bi-level SD outputs set for NTSC, PAL or PAL M/N. The SD and HD sync outputs and audio sync signals are all frequency locked to the reference regardless of the selected sync standard for the outputs.  
 
The SD sync outputs can be Color bars, Black Burst or Sync only with selectable 7.5 IRE pedestal for NTSC standards with adjustable burst phase in 8 increments.  
 
The sync generator is robust and temperature stabilized, suitable as a reference source with 2ppm accuracy.  
 
All user controls are located on the top of the module clearly labelled and easily accessible. This facilitates simple changes to module function and configuration without referring to a manual.  
 
The compact portable design makes it suitable for a wide range of applications in broadcast and mobile production environments.  
 
Note: 1080p 50Hz / 60Hz and 59.94Hz sync standards not supported.
