Product Overview

Compact with a versatile interface that can be used in a backpack or camera-mounted, and lightweight at only 3 pounds, LiveShot Portable is a bonded cellular solution designed for the most demanding field broadcasts. LiveShot delivers live, two-way, HD video and audio over a range of IP and cellular networks at latencies as low as less than 200mS. Utilizing sophisticated CrossLock VPN technology, LiveShot is able to make use of even the most challenging 3G/4G, Wi-Fi, and satellite networks to maintain a secure and stable connection. Used by TV stations, networks, sports franchises, and government organizations for a wide range of applications, LiveShot is ideal for streaming low-latency broadcast quality audio and video from anywhere internet is available.

“LiveShot has enabled us to cover live events from almost anywhere. Being able to shift from fiber, which can be difficult to access, to a modem-based system, we’ve been able to broadcast all kinds of new things live to people who may not be able to attend.
Joe Conlon, Townsquare Television

LiveShot Portable works with:

LiveShot Rackmount

Portable

LiveShot Portable is compact and lightweight. Supplied with Anton-Bauer gold mounts, and modifiable with a V-mount plate, LiveShot is designed to sandwich between a professional video camera and a battery (though it can be hooked up to any camera with an HDMI port, and carried in any way imaginable). Powered from the battery or by an external AC power supply, LiveShot weighs 3 pounds and consumes 8 watts of power.

Video

LiveShot encodes and decodes video to the H.264 codec standard, which is the state-of-the-art codec for high quality video using low network bandwidth. But not all H.264 encoders are alike. Within the standard, several lesser-quality profiles are available to conserve processing power. For optimal video quality, LiveShot encodes with H.264 HIGH profile. While this option is unavailable in competing products, all H.264 options that maximize quality over poor networks and decrease latency are implemented in LiveShot.

Audio

Comrex has years of experience encoding live, low-latency audio over IP networks for broadcast, and LiveShot shows it. In addition to standard AAC audio coding, LiveShot uses HE-AAC and AAC-ELD audio coding, both reducing network bandwidth and lowering delay.

Latency

LiveShot can encode and decode an audio/video stream with less than 200mS delay (depending on encoding mode and network factors). LiveShot uses an automatic decoder buffer manager to keep delay to an absolute minimum.

Channels

LiveShot delivers full-duplex video and stereo audio between the field portable and studio rackmount systems. In addition, a full-duplex cue channel is available between the systems.

CrossLock VPN

LiveShot utilizes CrossLock VPN to create a stable and secure connection across the public Internet.

The most advanced network management tool on the market today, CrossLock gives users the ability to use multiple IP networks together simultaneously. When a new network is introduced, Crosslock will immediately evaluate how much bandwidth is available, while factoring in latency and jitter information, and combine the two connections to take advantage of all available bandwidth.

More than just combining networks, CrossLock can also monitor and dynamically adjust how much of your stream is being placed on each network, in real time. When necessary, CrossLock can apply appropriate error correction, recovery, or concealment techniques. And when a network becomes unusable, CrossLock can isolate it, without any user intervention.

CrossLock also adds intrusion protection, encryption, and forward error correction.

Internal Wi-Fi Access Point

LiveShot Portable provides an internal Wi-Fi access point. This access point serves a mobile-friendly web page, which enables users to control their unit through their smartphone via their browser or simple-to-use mobile app. Additionally, LiveShot can agree to terms and conditions of public Wi-Fi hotspots in coffee shops or hotels, making it easy to take advantage of available Wi-Fi networks.

Wireless

LiveShot offers connections to wireless modems via two USB ports, which can be used simultaneously to increase the bandwidth of connections. This feature allows users to choose their 3G/4G data carrier and/or Wi-Fi modem, depending on their circumstances. Additionally, when the LiveShot Hub is connected, two more USB ports are available (4 in total).

Along with USB modem compatibility, LiveShot is equipped with a built-in Ethernet port, which can be used to connect to wired broadband IP networks, and Inmarsat BGAN and VSAT terminals.

Switchboard TS

Comrex Switchboard is a feature that allows users to bypass common IP networking snags (like private LANs and firewalls) by routing data through a private server maintained by Comrex.

Switchboard within the hardware codec enables the following functions:

  • Comrex codecs can sync with a cloud based server and deliver status information
  • Comrex codecs can determine their public IP address and the type of any NAT-style router ahead of the codec, and display that information to the user
  • Comrex codecs can display presence, status, NAT info and IP addresses of other codecs within the same fleet
  • Comrex codecs can share this information with codecs outside the fleet (Shares)
  • Comrex codecs can take instruction from the server on how best to traverse NATs when placing a call between two codecs

Switchboard TS is included in the purchase of any LiveShot codec.

Accessories

LiveShot Hub

For when your wireless coverage may not be ideal.

While the LiveShot Video IP Codec is designed to operate well when connected to the Internet via one or two 4G modems, a 4G network is not always available. When faced with a challenging 3G-only environment, the new LiveShot Hub will provide connections for up to four USB devices. The Hub provides additional 3G bandwidth and, because of LiveShot’s advanced dynamic aggregation capabilities, the Hub also provides modem redundancy – as the camera moves, LiveShot will continuously adjust the amount of contribution from each modem.

Additional connection options

Beyond 4G and 3G cellular connections, LiveShot can utilize many other types of networks. For instance, typical 2.4GHz and 5.0GHz Wi-Fi networks can be accessed via USB devices, while 5.8GHz wireless radio networks, new mobile MIMO networks, and satellite uplinks are available via LiveShot’s RJ-45 port for the harshest environments. Of course, you can also use a wired LAN connection when available.

Comrex Connect Modems

Professional grade modem for broadcast applications.

Bonded cellular technology and wireless data connections like 3G and 4G LTE have redefined the way remote broadcasts are done. In particular, USB cellular modems make connecting to these networks fast and simple. But the number of USB cellular data devices offered by cell phone providers is dramatically decreasing in favor of cellular Wi-Fi Hotspots. Additionally, many of the off-the-shelf modems offered by carriers are not designed to meet the rigorous demands of the 24/7 news cycle.

With this in mind, Comrex has developed Connect Modems – pro-grade, high performance cellular data modems. To ensure that Comrex customers experience the highest degree of broadcast reliable data transmission, each device comes in a ruggedized, industrial case with a carrier-certified, high gain antenna (2.1 dBi) and sturdy, customized mounting hardware for LiveShot Portable. LiveShot Connect Modems are available for Verizon, AT&T, and international carriers. LiveShot Connect will fit into LiveShot Rain cover sleeves for extra security and protection from the elements.
