Subjective Measurement
- Compression subsystem artifacts by a Human Visual Model as if a human
observer was present
- Desired compression quality is selectable
- Compression parameters may be varied immediately based upon subjective
feedback, leading to optimal compression ratios
- All SD and common HD formats supported
Continuous Monitoring
- Compression subsystem is continuously monitored as opposed to other,
one-time techniques
- Compression artifacts, such as dropped frames or edge artifacts, are
reported immediately
- System failures, such as noise or outright system failure, are detected
immediately
Synchronization
- Automatic synchronization if SMPTE timestamps are preserved by compression
subsystem
- Manual synchronization by visual determination of compression lag is
optional
- Synchronization lock, or loss of synchronization, are reported by the
monitor
Alarms
- Audible and SNMP alarms are reported
- Continuous average and peak error are reported
- Peak error second is available for review, locally or remotely
TCP/IP Interface
- Ethernet interface
- All parameters controllable by front panel or remotely
- Alarms are reportable by SNMP or TCP/IP
- Remote monitoring of all data is supported
Human Visibility Model
- VisibelTM reporting of subjective quality
- Tuned to SD / HD display parameters
- Detects edge artifacts
- Detects motion artifacts
- Detects dropped frames, quantization error, noise
