With the dual antenna switching two antennas are employed for better utilization of the signal quality; also see antenna diversity.
3G-SDI means 3 GHz Serial Digital Interface and stands for the HD video signal transmission via coaxial cable with a video raw data rate of 2.97 Gigabit/second.
For transmission of RF-signals over great distances we offer helicopter or other aircraft service to be employed as that can receive signals and forward them to ground units. Quite often aerial live videos will be transmitted from a helicopter directly to a ground unit.
Antenna diversity describes the use of several antennas in order to reduce the destructive interference of RF-radio airwaves. Airwave obliteration is often triggered by reflection of buildings or even out in the open. When using several neighboring antennas the chance of signal-reducing obliterating air waves will decrease. Using additional antennas the transmission safety of a signal will increase. Using several antennas for reception an integrated signal processing decides which of the adjoining signals provides the best level for the purpose.
Asynchronous Serial Interface stands for the manner of transmission of ASI-transport streams of broadcaster signals. With this technology several programs consisting of images, sound, and date may be transmitted as bundle. User information will be encoded and then transmitted in the form of ASI-transport stream, and it will be decoded after receipt.
