OmniTek Previews New 3D Monitoring Features at NAB 2012
Stand SL8424, NAB 2012
Innovative Test & Measurement Equipment manufacturer OmniTek will be previewing V2.4 of their highly successful OTM and OTR waveform analyser and test signal generator systems at NAB 2012 (Booth SL8424).
V2.4 sees the introduction of several new monitoring facilities. Two that particularly stand out are:
– a ‘real world’ representation of 3D images that can be scrolled to allow the scene to be viewed from different viewing positions
– a set of meters to aid camera alignment for both ‘3D’ and ‘2D’ set-ups
The meters assess factors including vertical alignment, camera roll, zoom level, image sharpness, colour gain and lift by comparing two images. Where a camera is being used for 2D images, this comparison is made against a reference image of the same test chart: where cameras are being used for 3D images, comparisons can be made both between an individual camera and a reference image and between ‘left-eye’ and ‘right-eye’ camera images of any chosen scene. The latter comparison also gives depth range information.
Particularly impressive are a set of ‘Colour Sabres’ used to indicate differences in colour gain and colour lift across the R,G and B components of the images (bottom-left in illustration). The angle of each sabre to the vertical directly reflects the extent of the difference in colour gain, while the positioning of the bottom of the sabre directly reflects the extent of difference in colour lift – and the response to any corrections you make is instantaneous, making the process of correction equivalent to manoeuvring the three sabres into their correct vertical positions.
A number of enhancements have also been made in the area of audio monitoring. New features include:
Logging Momentary, Sliding and Integrated Loudness to a CSV file
Displaying errors in the Z position within embedded audio both in the Status and over PPMs
Displaying errors in the CRC of the channel status block within embedded audio, also both in the Status and over PPMs
Selecting embedded audio services on the basis of individual channels rather than channel pairs (if required)
Applying the Audio Monitor Volume Control to AES output as well as to headphones (if required)
V2.4 also offers the option of adding markers defining user-defined levels to the graticules on the waveform display.
Visitors to NAB 2012 may also be interested to see the release versions of the 3D monitoring, loudness and AES routing features on display last year when V2.2 was previewed at NAB 2011 and the Stereo Mix-down, True Peak, Loudness Range and Dual Generator facilities that were added in V2.3 of the software.
