TKR-Cast broadcasts your desktop in real-time to every computer in your classroom, training institute, or office. Powered by efficient UDP multicast that streams 60 FPS video without choking your Wi-Fi router.
When streaming to 50 students, traditional unicast software sends 50 duplicate video streams over the internet. Your presenter laptop stutters, network crashes, and students experience 3 to 10 seconds of delay.
Your PC encodes the screen just once. The local network switch replicates the multicast frames to all 50 student monitors simultaneously. Presenter CPU stays cool and latency is imperceptible.
Broadcast to unlimited PCs on the same LAN subnet with zero incremental CPU or bandwidth overhead. 1 viewer or 100 viewers use the exact same network load.
When a student PC launches midway through a lecture, TKR-Cast detects the new receiver and fires an immediate keyframe refresh so their display connects without any black screen delay.
Direct integration with Windows Media Foundation ensures high-framerate hardware encoding with smooth fallback to software JPEG on older classroom computers.
High-resolution screen frames are sliced and reassembled across standard Ethernet MTU boundaries without router packet fragmentation or buffer drops.
Choose to broadcast your entire desktop, a secondary monitor, or a specific application window while keeping your personal notes hidden.
Works entirely offline. Conduct exams, lectures, and live code walkthroughs securely inside an isolated, air-gapped lab.
