What the ZAO does for mobile Broadcasting
Challenges live mobile video streaming
High quality mobile video streaming can be challenging from remote locations such as news-gathering situations or other live events that may include sports events being filmed over a wide area. Cameras may need to provide live video streams from a car, motorcycle, drone or helicopter that are moving at speed. The fluctuating availability of the 3G or 4G cellular network makes it hard with traditional systems to maintain reliable HD quality of live streaming content. The RASCOW algorithm combined with H.265 and its small size and weight, the Zao-S provides high reliability that is easily transportable even on a person or bicycle. It can easily be held in a body strap or mounted directly to the camera.
The miniature Smart-telecaster Zao-S maintains HD quality in low 3G or 4G bandwidth environments
Smart-telecaster Zao-S, the world’s smallest mobile H.265 HEVC hardware encoder that can be attached to any broadcast camera, solves these issues. Thanks to the compression capabilities of H.265, coupled with its RASCOW technology, high quality mobile HD live streaming is possible even in low 3G or 4G bandwidth environments. This makes it a first class product for encoding on the move for reliably streaming live broadcast quality content.
Smart-telecaster Zao-S: Minimal latency whilst covering live events
When streaming live events, especially news, a one second delay is very noticeable – Zao-s can provide minimal latency typically half a second but as low as 240ms. Production companies, broadcasters and journalists are no longer getting frustrated with reliability, delay and image quality. Broadcasters and production companies can save money without the need for satellite, RF services or an Outside Broadcast (OB) truck.

Key features Smart-Telecaster Zao-S:
Real time mobile HD video transmission direct from the camera
Smart-telecaster Zao-S is a portable video H265 HEVC encoder that compresses video in real-time enabling full HD live video streaming to anywhere in the world, while on the move.
Lightweight and small
Due to its lightweight (about 350g) and portability, the Zao-S can be carried either on body strap or can be mounted on a camera and connect either via HD-SDI or HDMI to the camera.
Supports H.265 video compression standard
Smart-telecaster Zao-S is equipped with the H.265 video compression standard. H.265 technology improves encoding and compression by approximately 50% compared to H.264 compression. As a result HD picture quality can be maintained even when the mobile phone signal strength becomes low and with very low latency (0.5 seconds).
Smart-telecaster Zao-S connects up to 6 SIM cards via external dongles that can be bonded together to form a single connection via 3G, 4G or WiFi. RASCOW technology monitors the changing mobile signal strength in real time and adapts the most optimum bonded combination of the 3G, 4G and WiFi connections. As a result the quickest and most reliable delivery across the internet is given to the decoding platform. This continues to give reliable video contribution even when signal strengths becomes low or fluctuates rapidly.
Easy to carry
Smart-telecaster Zao-S is a portable video encoder. The specially strap that comes with the product is easy to carry and operate.
Smart-telecaster Zao-S contains on internal battery and external battery
Smart-telecaster Zao-S supports a variety of mobile networks such as WCDMA, LTE, 3G, 4G, WiFi, ethernet, etc.
With multi-link technology in Smart-telecaster Zao-S you can use up to 3 mobile data cards simultaneously. This strongly improves the quality of broadcasting under weak signal conditions.
Receives multiple video streams
Our Smart-telecaster Zao-S viewing software can receive up to 4 video streams from 4 different camera units at the same time.
Supports 1080i standard for full HD TV
Smart-telecaster Zao-S supports the
HD-SDI/HDMI (1080i) video standard for full HD TV achieving unprecedented high quality digital video.
To guarantee secure communications Smart-telecaster Zao-S supports
authentication and encryption(AES 256bit).
Live with your Smartphone
STC for ML CAM is now available in the App store for mobile video transmission just using your iPhone.
Technology for optimized mobile communications
Click on the image to enlarge
Our technology for optimized mobile communication is called RASCOW (Real-time Auto-Speed Control based on Waterway model). RASCOW technology automatically balances the load between various network base stations during live broadcasting. This allows unprecedented stability in image transmission, even under network congestion or weak network signals.
The ZAO can be used in many ways, by just as many different customers. You can find some uses here, namely:
The Zao broadcasting video from a boat on open sea
The ZAO live streaming a radio broadcast
