Product	Description
IPM400A	IP Video Monitoring Probe for monitoring video over the IP transport network
VQNet™	Network wide diagnostics for video/network operations centers and headend operations teams responsible for video delivery through their networks. Connects to RFM300, MTM400A or IPM400A network probes
RFM300	ATSC/8-VSB DTV Monitor for ingest monitoring 8-VSB feeds
MTM400A	MPEG Transport Stream Monitor with DVB-S2 interface (Opt. S2) for monitoring satellite feeds MPEG Transport Stream Monitor with QAM interface (Opt. QA, QB2 or QV) for RF access network monitoring
QAM400A	QAM Digital TV Monitor for vverifying RF and TS integrity on a QAM channel at the output of Headend SEM or EdgeQAM devices at the RF combiner
VQS1000	Video Quality software for detecting QoE video impairments. Used together with the MTM400A, RFM300, IPM400A, and QAM400A for live monitoring of impairments and can also be used to analyze any Transport Stream file for off line analysis.

製品	概要
Sentry	Acquisition: Sentry's "Deep Dive" monitoring enables video service providers to detect Video & Audio level impairments in the incoming feeds (e.g. the SPTS from the satellite receivers). This includes perceptual video and audio QoE scoring (tiling, audio disruptions and audio level issues, etc.), black/frozen screen and audio silence.
Medius and Consul	For centralized management, reporting, alerting, aggregation and configuration of monitoring devices from the source to the edge of the network.

ビデオ／オーディオのQoE（ユーザ体感品質）測定
今日のデジタルTV放送は、さまざまなソースを元にして、数多くの装置を経由して最終的に視聴者に届けられます。放送素材に問題がなくても、素材が通過するさまざまな装置に障害があることがあり、ビデオに影響を及ぼすことがあります。素材に劣化が起こると、視聴者によるQoE（Quality of Experience、サービス体感品質）に影響を及ぼします。このような信号劣化はコンテンツの性質により発生したり、ランダムに発生したり、また定常的にQoEが低くなることがあります。コンテンツ品質が劣化する原因はさまざまです。ここで重要となるのは、ネットワークのさまざまなポイントで番組を客観的にQoE評価し、いつ、どこで劣化が発生したかをピンポイントで知ることです。

QoE: What it Means to Subscribers and Service Providers Webinar
Quality of Experience has emerged as the key focal point for cable operators. This webinar explores the results of a recent video network monitoring market study that points to the growing need for network monitoring. Learn about Recommended Best Practices for QoE monitoring, as well as strategic decisions related to Video Monitoring Deployments from Time Warner Cable.
Basic MPEG Overview / MPEG Made Easy Webinar
This introduction to MPEG covers Transport Streams, timing, and error types. Watch this webinar to learn about TR101-290 error types, and how it is giving way to ATSC Recommended Practice (A/78), a more meaningful measure of customer impacting events.
MPEG Timing and Synchronization Webinar
Whether your job is to design Encoders and Set Top Boxes (STBs), or to evaluate or integrate them, dealing effectively with timing concerns is essential. A Tektronix Buffer Analyzer can pinpoint the source of timing problems, and our webinar covering Program Clock Reference (PCR) issues and more explains timing principles and their impact on video quality.
Video over IP QoS (Network Monitoring of MPEG over a IP Transport) Webinar
This presentation on monitoring MPEG Transport Streams over IP networks describes test methodology used to ensure superior Quality of Service (QoS) in video.
