CallMe™ is a new cost-effective Subscription Codec service that lets contributors send high-quality broadcast audio back to the studio using the internet, without the need for dedicated hardware or software.

It has been developed to let Radio and TV Stations put a contributor on-the-air without having to send out an Outside Broadcast vehicle or for them to have any special hardware, software or even specific technical knowledge.

When subscribing to CallMe you will receive a dedicated webpage which connects directly to your chosen codecs with high quality, low delay audio. CallMe is compatible with BRIC-Link, ACCESS and STAC-VIP Talkshow system, taking full advantage of 12 lines on the STAC-VIP from a single webpage. Customise your page, fit your logo or change the background image to suit you and the only thing the contributor needs to do is click the link and click 'Call'.

There is a very large installed base of ISDN mixer-codecs from various manufacturers where the audio mixing and cue capabilities are well-understood and liked but these are only able to connect to the studio using ISDN. CallMe-TR is a small-size, low-cost IP Audio Codec supporting Opus/G.722 audio coding algorithms with stereo audio inputs and outputs on ¼" jacks plus RJ45 Ethernet connectivity. It has been developed as an add-on to provide a low-cost IP connectivity solution for these mixers. It is housed in a 108mm x 103mm x 44mm enclosure for table-top use and has two "Call" buttons on the front panel that provide "Quick Dial" connections and a single "Drop" button to disconnect. CallMe-TR is compatible with most IP Audio Codecs including CallMe-TS which provides a low-cost back-end for studio use. Four can be housed side-by-side in a 1-U rack.

The Industry-standard ACCESS Audio codec just got better with the addition of Opus Codecs and Dual-Streaming capability.

The Comrex ACCESS especially comes into its own on mediocre and contended connections as can happen when using 3G/4G over the public internet. BRUTE Broadcast-Reliable-UDP-Enhancement and Congestion Avoidance further increase the robustness of the connection where packet losses of 25% and above are barely noticed.

Of major significance, is the addition of Dual Streaming capability which allows the use of two or more different data paths to connect back to base. Until now, this has required the use of an expensive external network-combining device and this important capability is now included within the ACCESS-2USB. Any number of network connections can be enabled from any of the units and Crosslock can bond and diversify as well as allow you to monitor the connection.

OPUS Codecs which provide low-delay robust high quality audio are now included in the ACCESS family including the BricLink. Having OPUS as standard, allows compatibility with the Vortex CallMe Browser codec that lets guests and reporters connect directly to the Studio without the need to send out equipment or for the guest to visit the studio.

Unity Intercom provides a low-cost, novel and reliable IP intercom system that allows you to use your existing smartphones as Intercom stations.

Unity works by connecting over Wi-Fi or via a mobile network to a “Unity Server” providing Talk and Listen on multiple independent channels, as well as an independent programme audio feed. Unity can also display camera “On-Air” Tally and integrates with hard-wired communication systems like Clear-Com or RTS, letting you use Unity as a wireless station.

For the mobile intercom stations, the appropriate iOS or Android Unity app is downloaded (free), Listen and Talk channels are selected – then simply Push-to-Talk (PTT). The smartphones can be equipped with headsets – either cabled or Bluetooth – or used in speaker mode. Unity Clients are available for Mac, Windows PC and Windows Touch for use with a Tablet.

LiveShot 2nd Generation multi-stream codec from Comrex provides ultra-low latency, full-duplex HD/SD plus Comms over single or multiple IP connections. Using techniques carried over from the industry-standard ACCESS, LiveShot uses the same technology to stream video and audio over challenging public Internet connections such as 3G, 4G, WiFi and satellite, at bitrates from 32kb/s to 20Mb/s which it can combine for bonding and diversity without the need for additional hardware.

LiveShot uses state-of-the-art H.264 HIGH Profile video and AAC-ELD audio coding with less than 200ms delay, while its intelligent buffer manager keeps latency to a minimum on any network, making LiveShot the ideal tool for live two-way outside broadcasts. As well as the full-duplex video and audio stream, LiveShot provides an independent two-way cue / IFB channel which is available via Bluetooth or a wired headset in the field.

The LiveShot Switchboard Server provided by Comrex will allow remote management of your whole family of LiveShot codecs directly from a web browser and Android/iOS devices. Switchboard offers Crosslock VPN for improved stability and reliability along with redundancy over typical Video and Audio streams.

Our entire V-400 clock range has received an engineering and design refresh to provide enhanced operability, lower power consumption and additional features. The displays themselves are clearer and infra-red remote control for setup is included as standard, as is stopwatch operation. Additional digit and case colours also available.

The new TimeLord-µNet is a small, cost-effective solution to time referencing, a simple small form factor NTP time server that includes its own GPS antenna for an accurate time reference. TimeLord-µNet comes with PoE capabilities and will lock to GPS on power up with very little user interaction needed.

MCC is the BRIC IP Codec Management Software that helps control, maintain and monitor your ACCESS, BRIC-Link or MIDAS codecs. All functions from the remote end including Call/Drop and monitoring Packet Loss, Delay, Call Quality and many other parameters to help keep your broadcast seamless and hassle free with full control of your codecs from a single instance of Windows. Set up your profiles, change system settings, add new contacts all from the same display.

The V4X Intelligent 3G/4G Antenna is the ideal partner for any device that needs to stream audio or video using a 3G/4G mobile connection.

Using a patented intelligent multi-beam antenna array, V4X extends the range and throughput of a 3G/4G connection, bringing stable data throughputs around 2Mbps in most 3G locations without difficulty. Compared with the small aerials built into 3G/4G dongles, the V4X provides some 20dB additional gain with excellent stability. Intelligent selection of the cell with the best data throughput ensures optimum connectivity from any location.

Tests using V4X to connect to 3G/4G with an ACCESS IP Audio Codec in places where 3G/4G coverage is marginal and reception poor, have proved the remarkable capabilities of this combination for outside broadcast use; indeed they are in daily use for news, current affairs and sports coverage in places where only ISDN and wired connections would have been considered before.

The V4X acts as a Wireless Access Point and devices are then connected using a WiFi or cabled network connection, allowing the optimum siting of the V4X for 3G/4G reception whilst still providing excellent connectivity.

The new V4X-PRO with IP65 protection rating has been specifically designed for pole-mounting and outdoor use.

BRIC-Link II Front

Improving the standard set by its predecessor. BRIC-Link high-performance IP Audio Codecs are designed for point-to-point and point-to-multi-point Audio connections and use Comrex's revolutionary BRIC technology (Broadcast-Reliable Internet Codec) to deliver low-delay, jitter-free, high-quality mono or stereo audio over IP networks. Both BRIC-Link versions are capable of analogue and digital audio I/O, and can send linear or compressed audio with very low delay. Uncompressed PCM plus compressed FLAC Lossless Audio Coding and AAC algorithms are all included as standard. End-to-end contact closures and ancillary serial data are also provided. Support for OPUS has been seamlessly implemented and Dual-Streaming capability will be available through the units additional USB slot.
