Description

Comrex LiveShot delivers live, two-way, HD video and audio over a range of IP 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. Perfect for both point-to-point applications and field broadcasts, LiveShot is ideal for streaming low-latency broadcast quality audio and video from anywhere internet is available.

Features

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

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 (in bonding mode).

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 alternatively has the ability to use multiple networks to send identical streams (in redundancy mode).


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:
