Welcome to the cutting edge of wireless HDMI technology. If you’ve experienced the frustration of lag during screen mirroring or live streaming, you understand how essential smooth, real-time playback truly is. Meet the SVBONY TansAir3 ST4—a sophisticated HDMI transmitter and receiver that delivers both ultra-low latency and innovative infrared remote extension, creating a seamless, professional-grade experience without the cables. This groundbreaking device represents a significant leap forward in wireless video transmission, offering performance that rivals wired connections while providing unprecedented flexibility and convenience.
In this technical exploration, we’ll uncover how the ST4 achieves an impressive 0.06s low latency and how its IR infrared expansion enables effortless control of devices across different rooms—all completely wirelessly. We’ll examine the advanced technologies that make this possible and explore the practical applications that make the ST4 an ideal solution for both professional and personal use.
What Is Low Latency and Why Does It Matter?
Latency is the delay between a source signal (such as your camera or gaming console) and the output on your display. In video transmission, even minimal delay can lead to:
- Audio-video synchronization problems
- Lag during fast-paced gaming or live broadcasts
- A subpar viewing experience during presentations or streams
Conventional wireless systems typically exhibit latencies exceeding 0.1 seconds—perceptible to most viewers and particularly problematic for real-time applications. However, with a 0.06s latency, the ST4 operates at near-instantaneous speed, making it perfect for:
- Live broadcasting
- Competitive gaming
- Real-time monitoring on film sets
- Conference room presentations
How Does the ST4 Achieve 0.06s Low Latency?
A 0.06-second delay is roughly one-quarter the duration of a human blink (0.1–0.4 seconds). The magic lies in the integration of advanced 5GHz HDMI transmission technology and highly optimized encoding protocols that work in perfect harmony to minimize delay at every stage of the transmission process.
Key Technologies:
- 264 Encoding: Delivers efficient compression while preserving superior video quality.
- Dual-Band Support: Utilizes both 5GHz and 2.4GHz frequencies with intelligent auto-switching.
- Auto Channel Tuning: Dynamically selects the clearest channel to minimize interference.
- Direct Stream Transfer: Bypasses unnecessary processing to accelerate data transmission.
Together, these technologies ensure that video and audio are transmitted almost instantaneously—faster than the blink of an eye. The system’s sophisticated algorithms continuously monitor and optimize transmission parameters, maintaining consistent performance even in challenging wireless environments.
IR Infrared Extension: Control Beyond Boundaries
Among the most innovative aspects of the ST4 is its built-in support for infrared remote control. This functionality allows you to operate source devices—such as cable boxes or media players—from a different room, even through walls. The system supports multiple IR frequencies (30KHz/38KHz/47KHz/56KHz), ensuring compatibility with virtually all consumer electronics devices.

How It Works:
- Connect the IR emitter cable to the transmitter.
- Position the IR receiver near your set-top box or target device.
- Use your remote control from anywhere within range—the ST4 seamlessly relays the IR commands.
Perfect For:
- Enjoying TV in the bedroom while your set-top box remains in the living room.
- Controlling a presentation laptop from anywhere in the conference room.
- Managing media playback during live events without needing physical access to the device.
Plug and Play Setup
The ST4 is engineered for simplicity and user convenience. Its plug and play HDMI capability ensures:
- No additional drivers or software required
- One-touch pairing process
- Support for up to 4 receivers from a single transmitter
- Simply connect your devices, power on the system, and begin streaming immediately.
