The "Smart-telecaster series" is a solution that transmits high-quality video in real time using a public mobile line. Widely adopted from broadcasting media to public institutions such as police and fire departments, it is used for news reports and sporting events from disaster sites both in Japan and overseas.

Zao-SH, the latest model of the "Smart-telecaster series", is capable of ultra-short delay relay by scrapping and building the software of its sister product, Zao-S . It has a function that allows remote control of not only live broadcasts but also automobiles and construction machinery. By using 5G, even higher image quality, short delay relay, and stress-free remote control become possible.

Ultra Low Latency Smart-telecaster Zao-SH - 5g HEVC live video streaming

0.04 seconds latency Changing the game in live video transmission. 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. Buy Zao-SH from UBMS Dubai.

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.

Zao-SH is perfect for following Applications

• 5G Live streaming
• 5G video Streaming
• 5g HEVC live video streaming
• 5G low latency streaming
• Drone 5G streaming

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.

Shoot

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

Capture

The period from capturing video data from SDI/HDMI and performing color space conversion until it is input to the encoder

Encode

The encoding (compression) time

Transfer

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

Decode

The decoding (uncompression) time

AV Sync

The time until adjusting audio and video timing and outputting to SDI/HDMI

Display

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

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

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.

3. World's lightest

It is a palm-sized ultra-compact unit weighing 350g. It operates for approximately 60 minutes with the built-in battery and an additional 4 hours continuous operation with an external battery.

4. Stable and high speed

Mobile networks of different cellular carriers can be bonded into one network to significantly increase bandwidth and stabilize the communication speed.

5. High compression

Equipped with a highly efficient HEVC/H.265 hardware encoder, when compared to a traditional H.264 codec, it can transmit video with almost twice more efficiency.

Serial Control

• Support Serial Tunneling
• Same implementation as Zao-S and HDView
• Remote control use case

In Septembe 2020 Soliton update release of Smart-telecaster Zao-SH. This update includes bug fixes and specification changes. See below for details.

Smart-telecaster Zao-SH 3.0.7.0 / 3.0.7.0-5G

• Added support for interlaced signal input. The signals that can be input are as follows. 1080i 59.94 / 60/50
• Interlaced (i) / Progressive (p) is displayed in the input signal format display.
• Send-back audio is now available.
• As a measure to reduce the load, the sound quality has been adjusted. The sound quality is lower than the previous version Su.
• The automatic stop function of the communication modem has been implemented. If there is a communication path with poor line quality, turn off the power to the communication modem for 1 second and then connect. Resets the communication modem.
