Zao-SH Ultra Low Latency Mobile Encoder
The Zao-SH is a small mobile encoder that can live stream video from a remote location back to any destination. But with an incredible glass-to-glass latency of only 0,04s (40ms) over LAN, or 0,065s (65ms) over 4G.
The Zao-SH is an H.265 HEVC encoder that can be used in a variety of video contribution scenarios. From broadcast applications, such as news gathering, to public safety, law enforcement and military applications, the Zao-SH can be utilized to send an encrypted live stream from a broadcast or surveillance camera, drone, vehicle, body cam or helicopter.
Smart-telecaster Zao-SH is a 5G compatible ultra-low latency live video transmitter
It is equipped with next-generation transmission technology that reduces the glass to glass latency to 0.04 seconds (40ms) or less. The latency in live video transmission has been an important concern but the Zao-SH is able to transmit live video signal to/from remote areas in almost real time.
The Zao-SH can send a fully encrypted live stream, but simultaneously a return data feed can be sent from the destination back to the Zao-SH, for example to control a PTZ camera or to remotely control a drone gimbal.
The Zao-SH can live stream reliably over multiple bonded 4G SIM cards from different network providers, and /or can be utilized with a LAN connector.
At the receiving end, a Linux based software decoder will provide a video output of the live video. End to end latency starts at a remarkable 0,04s.
Specefications Smart-telecaster Zao-S
Explanation of each part:
The period from when the light enters the lens of the camera until video data is on the output of the SDI/HDMI terminal on the camera
The period from capturing video data from SDI/HDMI and performing color space conversion until it is input to the encoder
The encoding (compression) time
The period in which compressed data is extracted from the encoder and divided into communication packets for multilink transmission/reception. Includes time for error correction and packet sorting between each connection
The decoding (uncompression) time
The time until adjusting audio and video timing and outputting to SDI/HDMI
The period from SDI/HDMI output of the receiver to display the video on monitor (monitor-dependent part)
Function / Feature
1. Very short delay / RASCOW2
Ultra Low Latency
In order to solve the delay problem that occurs during simple transmission, Soliton developed RASCOW2, which is the second version of RASCOW (Real-time Auto Speed Control based On Waterway-model) Solitons’s original codec management/communication protocol. RASCOW2 makes the encoding procedure faster while controlling all transmission settings faster and more efficiently. This feature succeeded in significantly reducing the delay associated with compression.
2. Remote Control Function
Remote driving or remote operation
With almost zero latency, it is now possible to remotely control a car or construction equipment connected to Zao-SH in a remote location. Until now, the delay on live control transmission systems was too large and it was difficult to perform remote operations safely with a live video stream. With the ultra-low latency Zao-SH, it is possible to control machinery effectively with a live video stream that is in almost real time from a remote location.
