Dolby Audio Monitoring with Surround Sound display, Dolby Status, Audio Session, and Loudness Session displays


The Dolby Status display (Option DPE) gives an in-depth view of integrated or VANC metadata and comparisons of the Dialnorm value to Loudness measurements. Dolby E requires frame synchronization to the video signal and the guard band measurement provides a direct readout in terms of field and line location of the Dolby frame sequence. User-configurable thresholds for the Dolby E guard band timing measurement (Option DPE) are available as well as Dolby E guard band timing and trigger alarms based on their specific guard band parameters.

Full-featured Simultaneous Input Monitoring (SIM) boosts versatility

The Simultaneous Input Monitoring (Option SIM) capability takes multiformat monitoring to a new level. This capability helps operational staff quickly determine if a video quality problem existed in the input signal or arose in their facility. It enables engineering staff to quickly detect, diagnose, and resolve technical problems introduced in a piece of video equipment by comparing the input and output signals at each point in the chain. This feature is also especially helpful when checking for transparency during format conversion. 
 

Simultaneous Input mode comparing incoming and outgoing signals


FlexVu™ enables flexible and intuitive configuration of displays from two monitored inputs. The user can display simultaneous fault detection, status reporting, alarm generation, and error logging. SIM is ideal for transmission monitoring of simultaneous HD and SD programs. It is also ideal for monitoring stereoscopic 3D content in production and post-production applications by simultaneously monitoring the Left Eye image and the Right Eye image.

SyncVu™ is used in conjunction with SIM mode for 3D applications when input A is used for the Left Eye and input B is used for the Right Eye. When SyncVu™ is enabled, the Left and Right Tile displays are synchronized, so that if a picture tile is selected for Tile 1, Tile 2 automatically displays a picture tile in exactly the same mode as Tile 1. This enables the user to quickly configure the instrument identically for Left and Right Eye 3D monitoring.

The CaptureVu® feature allows users to capture, store, and download the data of a video frame to recreate displays and compare the live signal to captured data for easy troubleshooting of intermittent errors or for analyzing fault conditions at remote sites.

3D stereoscopic monitoring

The 3D stereoscopic monitoring and displays are available with Option S3D. A 3D image is comprised of a Left Eye and Right Eye image to be fed as two separate HD-SDI signals or combined within a 3G Level B format. Alternatively, the 3D signal can be carried in a single HD-SDI signal as a Side by Side or Top/Bottom image for the left and right images. A variety of different 3D monitoring modes are available within the instrument to assist the user in determining the difference between the Left Eye and Right Eye views. From this disparity difference between the two left and right images, the depth of an object within the image can be determined. 
 

Simultaneous 3D display of Left Eye and Right Eye signals with Difference Map and Overlay picture displays


For monitoring purposes a variety of displays can be set up within the Picture mode:

  • Difference Map Display – A subtraction of the two luma video signals L-R or R-L to produce a grayscale difference map image and see the difference between the left and right images
  • Red/Cyan Anaglyph Display – The left image is shown in red and the right image is shown in cyan, with identical left and right objects shown in monochrome. This allows the user to isolate differences between objects and gauge the depth of the object within the image
  • Green/Magenta Anaglyph Display – The left image is shown in green and the right image is shown in magenta, with identical left and right objects shown in monochrome
  • Checkerboard Display – This picture display shows a block of the image from the left eye and then the next block shows the image from the right eye in a 16×9 checkerboard pattern. This helps the user compare the levels and color of the signal between the left and right images

These modes help the user compare the disparity between the left and right images and can assist in interpreting the depth of the objects within the image.

3D stereoscopic measurement

For measurement of the depth of an object within the image (Option S3D) a Disparity Grid can be overlaid over the picture with a horizontal disparity between 1 to 15% of screen width and a vertical disparity of 50%, 25%, or 10% that can be selected by the user. The horizontal and vertical position controls allow the Disparity Grid to be moved around within the picture display to gauge the depth of objects within the image. 
 

3D Left and Right Eye RGB waveform displays with a Checkerboard, and Red/Cyan Anaglyph picture displays


A set of Disparity Cursors are also available for precise measurement of horizontal disparity of an object between the Left and Right Eye images. Readout is given of the pixel difference between the cursors and the percentage of disparity of an object.

Quad Diamond display for 3D alignment

The new Tektronix-patented Quad Diamond display (Option S3D) simplifies stereoscopic camera alignment by viewing a disparity histogram of the left and right signal from a signal level of 0 to 100% vertically for each of the components: Luma, Red, Green, and Blue. If the two cameras are well balanced the trace will form a vertical trace for each of the diamonds. A deviation in the trace indicates an imbalance between the left and right eye images that should be corrected using the various camera controls until the trace becomes vertical. This display can also be used in post-production for aiding the editor and perform color correction on the left and right images.

Superior data analysis capabilities for engineers and operators

The ANC Data Inspector (Option DAT) provides an industry-leading solution to help broadcasters easily and accurately ensure that all required VANC data is present and correctly configured through an intuitive ANC data display. 
 

ANC Data Inspector and CaptureVu provide detailed content analysis


In contrast to other solutions, the ANC Data Inspector enables operators to easily and quickly ensure that the VANC data is present and free of errors. When errors are detected, engineers are quickly guided to a more detailed view of the data packet content for further analysis.

With FlexVu™, each picture display tile can display different CEA708/608 Closed Caption and individual Teletext subtitles. Teletext subtitle pages can be decoded in either WST or OP47 format.

The Auxiliary Data Status display (standard on the instrument) provides summary information on Active Format Description (AFD) per SMPTE 2016, Video Index Aspect Ratio, Wide Screen Signaling (WSS), V-Chip, TSID, CGMS-A, Broadcast Flag, CEA708/608 Closed Caption, Teletext, and Time Code information. 
 

Monitoring of ancillary data (Closed Caption, Time Code, and AFD) using Aux Data Status


Today there is a wide array of metadata that provides information to a variety of equipment through the processing chain. Monitoring of this metadata is critical to ensure that the processing equipment correctly handles the signal. For instance, correct format of the AFD ensures that the aspect ratio on the display is correctly formatted and the automated AFD graticule is available for the Picture display along with the binary data and text description for easy monitoring.

The instrument can also monitor Dolby metadata embedded in the Vertical Ancillary (VANC) data space per SMPTE 2020.

The Datalist display (Option DAT) provides detailed information on the actual data values in HD/SD-SDI and 3G-SDI (with Option 3G) input signals. Users can easily use this display to locate protocol errors in the input signals.
