77. ware User Manual Iss 03 Bridging Module In This Chapter This chapter provides a summary of the Bridging Module available for the TES9 The following topics are discussed e Overview TES9 Software User Manual Iss 03 Bridging Module 7 1 Overview The Bridging module allows WST data in a SMPTE 259 625 line video signal to be bridged to VANC data in a SMPTE 292 10801 50 Hz video signal or vice versa The VANC data in the SMPTE 292 signal conforms to Operational Practice OP 47 In this chapter the term bridging refers to extracting the data from one video signal either Program 1 or Program 2 of the TES9 and inserting the data in a different format into the other video signal of the TES9 In practice bridging WST data will usually involve the use of two TES9s one to bridge from WST in the 259 video to OP 47 packets in the 292 video and then a second TES9 downstream in the 292 video path to bridge from OP 47 packets in the 292 video back to WST data in the 259 video Before configuring the Bridging module you must specify the Requested Video Format on both the Program 1 and Program 2 tab of the main menu For the video signal to be used to extract or insert the WST data the Requested Video Format must be set to SD 625 Line For the video signal to be used to extract or insert the OP 47 packets the Requested Video Format must be set to match the video format being used This will usually be HD 10801 50Hz When a Bridging
