# Introducing UP.Lens

UP.Lens is a cloud-native live video monitoring and observability service that combines broadcast-grade multiviewer confidence with deep, time-correlated analytics. It enables operations teams to validate video, audio, caption integrity, and ad signaling (SCTE-35) across live broadcast workflows operating in the public cloud.

UP.Lens is purpose-built for cloud environments. It is designed to operate alongside dynamic, elastic cloud workflows, providing a scalable and cost-efficient way to monitor 10 to 300+ simultaneous contribution feeds, including event-driven spikes.

UP.Lens can be deployed as a stand-alone cloud monitoring service or used in conjunction with Telestream’s Capture, allowing teams to extend observability across end-to-end cloud production workflows.

At its core, UP.Lens unifies two capabilities that have historically existed in separate systems: real-time visual confidence and historical, time-aligned analytical insight. This allows teams to see issues as they happen and immediately understand the conditions that led to them, without switching tools or reconstructing timelines after the fact.

# Key Benefits

* **End-to-end live video performance visibility:** Gain deep, real-time insight into the health and performance of your cloud-based live video workflows, from source contribution to final distribution.
* **Fast incident resolution:** Advanced monitoring helps pinpoint disruptions, identify root causes, and accelerate response times, minimizing impact and keeping audiences engaged.
* **Unified monitoring experience:** A single, cloud-native dashboard correlates signals across the entire live-stream pipeline, simplifying operations and enhancing operational confidence.

# Key Features

* **Eyes-on-glass confidence multiviewer:** UP.Lens delivers an instant-on, broadcast-grade multiviewer that restores direct visual and audio verification for cloud-based live workflows.
* **Configurable multiviewer dashboards:** Operators can tailor layouts, select widgets, and surface high-priority signals for proactive monitoring.
* **Penalty box sorting:** Degrading or failing feeds are automatically surfaced, allowing operators to react up to 60 seconds faster.
* **Low-latency proxies:** Full frame-rate video and audio level monitoring ensures tangible, real-time verification.
* **Shareable Views:** Live multiviewer mosaics can be securely shared with external partners without requiring a Telestream account.
* **Troubleshooting time-machine (Incident rewind):** UP.Lens maintains a continuously indexed history of signal behavior to accelerate diagnosis and post-event analysis.
* **Time-aligned diagnostics:** Visual thumbnails, error events, and KPIs (such as jitter and packet loss) are correlated at the exact moment alarms fire.
* **Historical trending:** Engineers can rewind to see precisely when issues began and how conditions evolved leading up to failure.
* **Retrospective analysis:** Supports post-event review, compliance verification, and operational improvement without manual reconstruction.
* **SCTE-35 and caption monitoring:** Real-time validation and historical reporting help protect ad revenue and meet regulatory obligations.
