Cobham — Solo7 HD Nano TX: This is “one of the smallest HD transmitters,” said Sam Medler, special projects manager for
Lubitch: Beamr Video is “a way of delivering 4K now instead of waiting two years” for HEVC
Beamr — Video: This is “a perceptual quality filter that is highly correlated with human vision,” so it can “eliminate all the redundancies in video that are beyond human vision,” allowing it to offer the same quality of video at half the bitrate, explained Beamr president Eli Lubitch. At IBC it showed 6Mbps and 3Mbps versions of a 1080p movie side by side with no noticeable difference between them. It can either be used to save bandwidth, or to offer higher quality video, such as HD to mobiles or 4K, at the same bitrate. “It will preserve all the settings and profiles, so for the clients it is transparent. You don’t need any special software in the receiving card.”

Dejero’s Live+ VSET can use cellular links to enhance satellite transmissions
broadcast. “The really cool thing is that the latency in HD is just 15 milliseconds.” The 100mW transmitter draws only 7W of power, weighs just 70g, and has both HD-SDI and HDMI inputs. It can transmit H.264 video at up to 30Mbps. In
64QAM it has a range of 50-100m, in 16QAM (about 15-20Mbps) the range is up to about 300m, while in QPSK (10-12Mbps) it is up to about 500m. From hilltop to hilltop, line of sight, it can do 4-5km.

Dejero — Live+ VSET: This rack mount 1U transmitter will allow outside broadcast or ENG vehicles to transmit over cellular, microwave and satellite, including transmitting live while driving to location, and to then seamlessly transition to satellite on arrival. Its adaptive bitrate encoder reduces latency and improves the reliability of satellite video feeds. For example, during rain fade or other atmospheric conditions that cause Ka-band satellite bandwidth to decrease, the system will automatically pick up the drop in bandwidth by transmitting via cellular networks. In ideal conditions when most data is being sent over satellite, it takes advantage of the lower latency of a cellular connection to deliver an overall decrease in latency on the entire Ka-band system.
