TLS Viewer turns your iPhone or iPad into a wireless video-village monitor for NDI® sources on your local network. Made by a working video-assist operator for film and commercial sets, it does one thing well: show the feed, clearly, with the tools you reach for between takes. WHAT IT DOES • Finds NDI® senders on the same Wi-Fi automatically. No IP addresses to type. • Single-source monitor with pinch-to-zoom and pan for focus checks. • Multi-view grid to keep several sources on one screen. • Histogram and false colour for exposure calls. • Live link stats: frame rate, latency, dropped frames, so you know when the network is the problem. • Bandwidth switch: full quality on a clean network, proxy mode when the Wi-Fi is crowded. • Reconnects on its own when the network changes. The last frame stays on screen with a clear status chip. • Keeps the screen awake while you are monitoring. Tap once to hide all controls. WORKS WITH Any NDI® sender on your network: switchers, capture apps, cameras, and video-assist systems that publish NDI®. A built-in demo source lets you explore every tool without a sender.
