Tektronix Enhances Sentry
Tektronix says it has added significant new capabilities to its Sentry digital content monitor. The Sentry 5.0 release enables Sentry to perform in-depth monitoring of video streams at full line rate – 1 Gbps per unit. This performance enables video service providers to monitor hundreds of video streams per unit, which reduces the number of Sentrys to comprehensively monitor a large multi-channel lineup.
Sentry 5.0 introduces eMOS, or Perceptual Video Quality, which helps service providers tackle content errors where the QoE score is good but the program suffers artifacts due to over-compression, which is common in motion intensive programs like sports. In addition, the new release includes GOP length statistics, RTP support and new reason codes that help service providers quickly understand the source of an issue.
