• Audio Silence and Audio-level Issue Detection

• Detect Black Video, Frozen Video, Tiling/Macroblocking

• Perceptual Video Quality (eMOS)

• Live Thumbnails

• User Triggered and Alert Triggered Stream Captures

• Stream to View

• Historical Reporting and Graphing

• Transport Stream Bandwidth Graphing

• Program Group Bandwidth Graphing

• Carousel Monitoring (SA-BFS, DSM-CC, tru2way™)
