Modular Video Transmission Platform
We have developed a unique FPGA (Field Programmable Gate Array) based technology that enables network video and audio transmissions superior to HDTV with an added latency of less than 1 millisecond. The device is a real-time system with all video and audio processing done in the FPGA.
The device delay is so small that, after adding network delay, real-time delay-critical applications can be realized over long distances. For example, musicians can play together in real time between cities and countries. Video quality exceeds current HDTV broadcast standards and enables live TV production with multiple cameras and in multiple locations.
The device is very easy to use, an all-in-one device, requiring no computer or software, small, lightweight, fanless, 100% silent.
- Video up to 1080p60 (4K or even 8K video versions available on request).
- Fully bidirectional operation, all video and audio signals are transmitted and received in the same device.
- A true FPGA-based real-time system with minimal added latency.
- All-in-one hardware, no need to install a PC or PC card.
- 8-channel analogue audio transmitted with uncompressed 24 bit/48 kHz encoding.
- 4-channel 3G-SDI audio and 2-channel S/PDIF audio.
- TICO video compression with very low latency.
- Small size, light weight, no fan, 100% silent for music applications.
- Easy configuration using the integrated web GUI, front panel buttons or command line.
- Distance collaboration in the performing arts, between institutions internationally.
- Distance master classes, rehearsals, auditions, cultural exchanges.
- Distributed performances with artists in different cities, countries or continents working together in real time for audience in multiple places.
Delay and real-time remote collaboration
- Live performances over a computer network are critically sensitive to low end-to-end audio and video latency.
- For classical music, the end-to-end delay must be less than approximately 20 ms, depending on the instruments and style of performance.
- The packet propagation delay over a network in Europe is in the range of 10 to 20 ms, leaving only a few milliseconds for additional transmission device delay.
- A pair of MVTP devices (transmitter and receiver) adds a delay from about 1 millisecond to several milliseconds depending on the receiver buffer setting and the video format.
