See and Solve with Tektronix Displays

 
Quad Tile display of Alarm Status, Error Log, Video, and Audio Sessions. 

The “See and Solve” displays in Tektronix video monitors simplify video monitoring tasks such as calibration, error detection, and content correction allowing the user to detect errors at a glance and troubleshoot them efficiently.

Tektronix displays offer the sharpest CRT-like trace quality for clear waveform monitoring with the look and feel of an analog display. The familiar video waveform display can show SD/HD/3G-SDI signals in RGB, YPbPr, YRGB, or pseudo composite. Signal components can be displayed in either Parade or Overlay mode.

With several sweep rates and easy control of vertical gain and horizontal magnification, you can efficiently monitor and measure video waveform parameters.

Specialized displays provide summarized, yet comprehensive reports of alarms, session, and status of content. Powerful displays such as Video Status show a condensed view of error statistics, signal format, presence of ancillary data, and more. These Tektronix-exclusive displays simplify monitoring tasks by providing important content information at a glance.

The Black and Frozen frame detection can be used to alert the operator to a problem in the transmission chain. These and other errors can automatically be logged in the Error Log and provided as a report.

Alarms, Quality Statistics, and Logging – Thorough and Fast Content Verification

The WVR5250 offers a variety of displays designed to show status at a glance, in addition to the status bar continually displayed at the bottom of the screen.

A comprehensive overview of the video content status is presented in the Video Session display for both SDI and HDMI interfaces. Offering a time-based compilation of information, this screen is ideal for presenting evidence of compliance after content screening. Information on input format and session time is presented, along with statistics on Error Detection and Handling (EDH) / Cyclic Redundancy Check (CRC), gamut errors, and Black / Freeze frame detection. For an HDMI source, the HDMI formats (Colorimetry, Color space, Color depth, TMDS clock, HDMI/DVI ID, Pixel repetition rate, Quantization range), as well as HDCP status, are also presented. An EDID information display helps to diagnose connectivity issues when they occur.

The Alarm Status display provides continuous information on the state of each condition currently being monitored by the instrument.

To support unattended monitoring and QC applications, as well as provide documentation for service-level agreements, these instruments maintain an error log of 10,000 events, which facilitates the detection and correction of problems. Log entries are recorded with date, time of day, and time code (VITC, LTC, ANC). The error log can be downloaded to a USB memory stick or through a network connection to .TXT or .HTM formats for easy record keeping and processing on spreadsheets or database software.

Picture Display – Quick Visual Confirmation and Precision Content Adjustment
 
Picture display with Safe Area Graticule and AFD information. 

For a qualitative view of the content, a full-color Picture display is offered, which can be displayed as a full-screen presentation. This display is compatible with all input formats and features automatic adjustment for aspect ratio and number of active lines.

You can select bright-up conditions that show the location of RGB or composite gamut errors on the Picture display. The Line Select mode shows the location of the line currently selected within the Picture display.

Users can choose from several Safe Action and Safe Title graticules on the Picture display which help editors and operators easily identify incorrectly positioned video content such as graphics, titles, or logos.

Graticule choices include the Safe Action and Safe Title graticules defined in SMPTE RP218, ITU, and ARIB standards, plus two sets of completely flexible, user-definable graticules. These graticules facilitate editing tasks and reduce the need for format conversions.

Patented Tektronix Gamut Displays – Efficiently Detect and Allow Correction of Gamut Problems
 
Spearhead and Diamond gamut displays. 

The Tektronix-patented Diamond, Split Diamond, and Arrowhead displays simplify the process of verifying gamut compliance and are ideal for colorists, editors, and operators to visualize whether the content is RGB or Composite Gamut compliant with a single glance. Plus, they are designed to help isolate the Out-of-Gamut component just as easily. For SDI component content that is destined for broadcast in composite systems, the unique Tektronix Arrowhead display can be used to monitor Composite Gamut compliance without the need for a separate encoder. Within this display, a separate upper and lower luma-only gamut limit can be applied.

Each of these displays offers user-selectable gamut thresholds so operators can set monitoring limits appropriate to their specific operation and include a preset for EBU-R103. You can also select bright-up conditions to see the location of gamut errors on the Picture display. In addition, gamut monitoring is fully integrated with the powerful alarm logging and reporting capabilities of the WVR5250.

Two-channel Simultaneous Monitoring (Option SIM)
 
Two-channel simultaneous monitoring of waveform and picture input, ideal for monitoring multiple camera inputs. 

Two-channel Simultaneous Monitoring (Option SIM) is ideal for monitoring multiple camera inputs or comparison of incoming and outgoing transmission chains. In mobile truck (OB van) applications this allows the operator to compare two different camera inputs with picture and waveform displays. This capability can also help 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.

HDMI Input with HDCP
 
HDMI input, including EDID information, available in multiple displays. 

HDMI is used in a wide variety of applications, from cameras to Blu-ray players and set-top box devices. The HDMI signal can have HDCP enabled, which prevents illegal distribution of copyrighted content. HDCP is typically enabled for consumer type devices such as Blu-ray players and set-top boxes. For other applications, such as cameras or other professional devices, HDCP will not be enabled, allowing copying and distribution of the copyrighted content. Information on HDCP is found in the Video Session display, along with information on the video format. The HDMI interface also contains metadata, and a summary of this information is found on the Aux Data Status display. When HDCP content is present, the SDI output and picture display on the DVI-I output will be disabled and an HDCP compliant monitor will be required to view the picture display on the switched HDMI output. The Video Session display provides summary information related to the HDMI metadata for an HDMI input. Additional metadata presence can be found in the Aux Data Status display that provides data values of the input and output EDID information.

3D Stereoscopic Monitoring
 
3D monitoring of left and right eye. 

3D stereoscopic monitoring and displays are available for SDI signals on the WVR5250 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 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. 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
 
3D monitoring using a disparity grid. 

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. 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 showing 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, then 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.

The instrument provides 16-channel embedded digital audio monitoring with Audio Bars, Lissajous Displays, Surround Display*1, and a front-panel headphone port for easy compliance verification of digital audio without the need for an additional piece of equipment. Flexible mapping of the embedded audio inputs to the audio bar displays allows for a variety of audio mixes to be supported from multiple stereo signals to surround and stereo support.

The Surround Sound1 display provides intuitive graphical representation of channel interaction in a surround sound system. The Bars display provides indication for faults, audio levels, and provides indication of the presence of a Dolby format. The flexible Lissajous display allows the selection of any two audio channels.

Loudness measurements are made to ITU-R BS.1770-3/1771, EBU R 128, and ATSC A/85 recommendations. A Loudness meter (with Option LOUD) is available within the Audio display that provides Short and Infinite Loudness measurements. The Loudness session display graphically plots Loudness measurements over time, from 90 seconds to 30 hours. The Loudness measurements can be downloaded through the network or saved to USB for further analysis.

Specialized audio displays provide deeper inspection of the signal and make the WVR5250 instrument a comprehensive compact waveform and audio rasterizer. The audio session displays summarize levels, faults, and number of active bits for each channel. These instruments also feature Audio Control Packet Data and Channel Status displays.

The Dolby metadata can be monitored within the instrument using the Dolby Status display that gives an in-depth view of VANC Dolby metadata that complies with the SMPTE 2020 standard. The user can also choose to monitor Dolby E guardband timing information from one of the embedded audio channels.

Facility Timing Made Easy
 
Timing and Lightning displays simplify timing tasks. 

Synchronization is one of the most fundamental and critical procedures in a video facility. Every device in a system must be synchronized in order to successfully create, transmit, and recover video pictures and audio information. The intuitive Timing display clearly shows the timing offsets between HD and SD signals relative to the reference. (Timing display is not available for HDMI inputs.)

This Tektronix-patented Timing display makes facility timing easy through a simple graphical representation which shows the relative timing of the input signal and the reference signal (or a saved offset reference) on an X-Y axis. Simply adjust the timing of the equipment until the circle is within the center of the display for precise, direct measurements of vertical offset in number of lines and horizontal offset in μs.

The Lightning display shows luma and chroma amplitudes and helps users verify component timing using a color-bar signal. The Tektronix-patented Bowtie display complements the timing measurement capability of the Lightning display. Using a special Bowtie test signal in component format, this display helps make precise, accurate measurements of interchannel amplitude and timing.

Troubleshoot Signal Paths

A simple test signal (Option GEN) can be generated from the SDI output that produces 100% or 75% color bars along with pathological test signals. This can be useful for troubleshooting a signal path or piece of equipment without the need to carry an additional generator.

Superior Data Analysis Capabilities for Operators and Engineers (Option DATA)
 
ANC Data Inspector provides detailed content analysis. 

The ANC Data Inspector 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.

In contrast to other solutions, the ANC Data Inspector enables operators to quickly and easily 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.

Closed Caption (CEA708/608) and individual Teletext subtitles can be simultaneously decoded and displayed within the Picture display. Teletext subtitle pages can be decoded in either WST or OP47 format.

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

The Auxiliary Data Status display 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.

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 of the WVR5250 along with the binary data and text description for easy monitoring.

 
Datalist display provides detailed pixel-by-pixel information. 

The Datalist display 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. (Datalist and ANC Data Inspector are not available for HDMI inputs.)

The right side of the display shows the data values in hexadecimal, decimal, or binary format and uses the following color coding for easy identification of data types and errors:

  • Green – Active
