LiveShot Portable
A portable IP video codec for live wireless newsgathering
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 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:
Portable
LiveShot Portable is compact and lightweight. Available with Anton-Bauer gold mount plates or V-mount plates, LiveShot is designed to sandwich between a professional video camera and a battery (though it can be hooked up to any camera with a consumer digital video 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
LiveShot utilizes CrossLock technology 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.

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
The Comrex Connect Modem is designed to support the unique needs of remote broadcasters. A high-powered, industrial strength 4G/LTE modem outfitted with a high-gain antenna, the Connect Modem is more powerful than most USB data modems available on the market, to handle the heavy data load of a broadcast over IP.
Leverage Two Connect Modems
Leverage the power of two Comrex Connect Modems with your LiveShot Portable for twice the reliability. CrossLock technology, our sophisticated custom reliability layer, bonds the available cellular networks and sends a single media stream, along with background and error correction information, resulting in a higher level of reliability for remotes. LiveShot Portable supports up to two Comrex Connect Modems.

“The form-factor of LiveShot Portable is unique… which distinguishes it from other bonded cellular products. And LiveShot also contains some unique features, like two-way video and IFB capability.”
LiveShot Is “a TV Studio in a Single Box”
“Comrex equipment has helped our show be successful over the years — we’ve used it to make reliable field connections all over the world. If you need to take your show on the road, Comrex LiveShot is the best product out there.”
North Metro Television Goes Wireless with LiveShot
“I was initially impressed by the quality of Comrex LiveShot’s visuals, but it was the low delay that impressed me the most. Over an AT&T cellular network, using an antenna, we can usually expect about a half-second delay.”
Live From The Field [with Neumann University]
“LiveShot is easy to use. It’s been great to be able to control the equipment with an app. I can get it up and on the air in seconds. LiveShot is one of the unsung heroes of bonding technology – it provides so much capability in such a small package.”
