Title
Critical RF Measurements in Cable, Satellite and Terrestrial DTV Systems

The secret to maintaining reliable and high-quality services over different digital television transmission systems is to focus on critical factors that may compromise the integrity of the system. This application note describes those critical RF test measurements which help to detect such problems before viewers lose their service and picture completely.

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。
Solving Intermittent Transport Stream Problems with CaptureVu Technology

CaptureVu technology allows you to set an error break point on an incoming real time or stored MPEG transport stream. By setting specific conditions for CaptureVu technology you allow the analyzer to find intermittent problems for you, trigger a recording to memory, or stop analysis to allow you to drill down to the route cause of an issue quickly and efficiently.
