ClearView is a highly advanced test & measurement analyzer providing source and processed video recording, file importing, automatic alignment, and a variety of quality metric assessments for any content resolution or frame rate. Comparative playback modes are a unique feature applied up to 8K ultra high definition uncompressed sequences*. This combination of quality analysis features allow users to effectively quantify the human subjective experience.

ClearView is offered as a hardware system, or applied in Cloud SaaS, or local software license.

ClearView full-reference scoring methods:

- ΔEITP: Provides an objective assessment of whether a difference between two colors may be visible between two versions of a given program

- VMAF: Video Multimethod Assessment Fusion is tailored for quality assessment of streaming video services

- MS-SSIM/DMOS: Multi-Scale Structural Similarity Image Quality Assessment on both MS-SSIM and DMOS scales, where DMOS is the difference between the mean opinion scores of the reference and processed video

- JND: The number of human observers that must be gathered to end up with at least one person who believes that the processed video is at least as good as the reference (just noticeable differences)

- PSNR: Peak Signal-to-Noise Ratio, the ratio between the maximum possible power of a signal and the power of distorting noise affecting the fidelity of its representation

- aFREQ: Audio performance metric for finding gross errors versus each reference audio channel. aFreq includes an audio-video offset measurement or lip sync value for a selected channel in program

ClearView no-reference scoring methods:

- NIQE: Natural Image Quality Evaluator, a completely blind, distortion free, no reference, image quality assessment index

- aPEAK: True-peak audio measurement per channel according to ITU-R BS.1770-3

- LKFS: Audio loudness measurement per program according to ITU-R BS.1770-3

- Spatial: Calculates the activity power of a video frame, a higher number indicates more changes in the frame

- Temporal: Calculates the changes between successive video frames, a zero indicates a frozen frame

The Venue Player system is a compact, reliable, multiple output video server supporting up to eight full HD or two UHD outputs, all with up to sixteen channels of embedded audio. Multiple storage options allow for hours of playout of uncompressed YCbCr or RGB, 8, 10, or 12 bit video from a single 1RU package. The Venue Player system is unmatched in number of outputs, small size and storage capacity.

The Venue Player’s control application is the Venue Player GUI or browser based Venue Player Manager which can control video sequences in several ways. One or more units can be instructed to start playout based on system clock time (NTP synchronized) or an incoming LTC time code value. Play commands can be applied to one or several sequences at a time. Each unit has a direct user interface via keyboard & mouse, or full set up and playback control via networked device such as a tablet or laptop with web browser. Functions can also be accessed from a command line scripting interface or VDCP over IP.

Venue Players also come with 10G IP or 12G-SDI interfaces with multiple storage configurations.
