Comrex LiveShot

Richiedi Informazioni



Comrex LiveShot delivers live, two-way, HD video and audio over a range of IP networks at latencies as low as 200mS. With sophisticated CrossLock VPN technology, LiveShot goes beyond bonded cellular, making use of even the most challenging 3G/4G, Wi-Fi, and satellite networks. Compact with a versatile interface that can be camera-mounted or slung over your shoulder in LiveShot Pouch, and light-weight at only 3 pounds, LiveShot is portable and designed for the most demanding field broadcasts. Used by TV stations, networks, sports franchises, and government organizations for a broad 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

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. CrossLock adds intrusion protection, encryption, and forward error correction. Using CrossLock, LiveShot units are able to connect at the touch of a button.

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.
