Digigram at BroadcastAsia2014

At BroadcastAsia2014, Digigram has announced it will feature "a complete range of products designed to address the requirements of all applications and budgets."

The company will highlight a new RAVENNA/AES67-enabled sound card for low-latency synchronous audio-over-IP distribution over LAN; the low-cost, ultralow-latency IQOYA *CALL and IQOYA *CALL/LE audio-over-IP contribution codecs; the IQOYA *LINK and IQOYA *LINK/LE stereo audio-over-IP distribution codecs; the high-density IQOYA *SERV/LINK multiple-stereo or multichannel audio-over-IP codec for professional IP audio distribution; and the latest release in the company's AQILIM family of video encoders for professional video broadcasting and distribution over IP networks.

Audio Distribution Range

IQOYA *SERV/LINK Multiple-Stereo or Multichannel Audio-Over-IP Codec for Professional IP Audio Distribution
Digigram's IQOYA *SERV/LINK incorporates multiple distribution codec instances and the company's FluidIP™ technology on a single processing hardware platform to simplify the transport of multiple audio programs (mono, stereo, multichannel) over IP networks in a high-density format.
The IQOYA *SERV/LINK codec allows users to configure multiple-stereo or multichannel solutions for links between studios and between the studio and transmitters, DVB operators or content delivery networks.
In its compact 1-RU version, the solution can handle up to eight stereo analog channels, 16 stereo AES/EBU channels, 32 stereo MADI channels, or multichannel LAN IP audio interfaces (Livewire and RAVENNA) and up to 64 codecs with multiple GPIOs and RS232 ports for auxiliary data tunneling.
The scalability of the system allows users to mix and expand the supported audio I/Os, and a larger 4-RU version provides even higher channel density. The solution supports analog, AES, MADI, Livewire, or RAVENNA audio connectivity, and multiple audio codecs (PCM, MPEG L2 and L3, AAC, apt-X) and is one of the industry's few audio-over-IP codecs that can simultaneously stream raw RTP, HTTP, and MPEG-TS/IP streams.

IQOYA *LINK and IQOYA *LINK/LE Audio-Over-IP Codecs
The IQOYA *LINK and IQOYA *LINK/LE codecs are full-duplex encoding and decoding solutions for IP-based studio-to-studio and studio-to-transmitter links, as well as audio program delivery to DVB operators. Developed in collaboration with European telcos, the IQOYA *LINK/LE codec is a cost-effective version of Digigram's full-featured IQOYA *LINK codec.
Based on FluidIP™ technology, the smart IP audio streaming engine developed by Digigram, both IQOYA *LINK and IQOYA *LINK/LE boast high mean time between failures (MTBF), low back-to-back latency and a host of features "that guarantee audio quality and continuity".
"With audio synchronisation based on Network Time Protocol (NTP), these Digigram solutions enable operators to provide a seamless listening experience for users on the go — even as they move among the contiguous transmitters used in a multifrequency network," a statement from the company said.

Video Distribution Range

AQILIM *FIT/LE Video Encoder
The AQILIM *FIT/LE professional video encoder is a solution for live event broadcasting over an IPTV network or multiscreen video distribution over the Internet. With input options and compatibility with leading content delivery networks (CDNs), the encoder is suitable for live video streaming applications, including filmed radio; live distribution of corporate, sporting, or news events; the creation of WebTV; the live distribution of electronic sports events and live education via e-learning.
The AQILIM *FIT/LE encoder connects directly to the camera or video mixer, capturing live video and streaming encoded video either to an IP network or to the CDN responsible for Internet distribution of live video. A straightforward Web-based interface eliminates the need for specialised user training or dedicated operators. The robust 1-RU encoder is available with analog, SDI, and/or HDMI video inputs.

Audio Contribution Range

IQOYA *CALL and IQOYA *CALL/LE Audio-Over-IP Codec for Professional IP Audio Contribution
Digigram will highlight IQOYA *CALL and IQOYA *CALL/LE codecs, which allow users to build low-latency IP audio contribution links while keeping costs under control. These codecs belong to Digigram's Mobile Studio and Ultra Mobility solutions.
IQOYA *CALL protects the investment of broadcast institutions within large fleets of heterogeneous ACIP EBU Tech 3326-compatible equipment managed by SIP infrastructure. Its front panel enables usage in all OB situations, the company says.
IQOYA *CALL/LE is ane addition to the IQOYA range of IP codecs. It provides full-duplex IP audio sessions over the Internet and wireless connections, thanks to its smart signaling and symmetric RTP connection mode. As with all IQOYA family members, IQOYA *CALL and IQOYA *CALL/LE codecs share the benefits of Digigram's FluidIP™ IP audio streaming engine, including smart jitter, packet loss and drift management; quality of service optimisation; end-to-end dual-stream redundancy; and stable ultralow latency.

Audio Production Range

LX-IP RAVENNA PCIe Sound Card
The LX-IP RAVENNA PCIe sound card, the first RAVENNA-enabled product developed by Digigram, features ultralow latency — down to one audio sample per IP packet — and up to 256 RAVENNA I/O channels from multiple RAVENNA streams. The solution makes it easy to record and play as many as 128 audio-over-IP RAVENNA channels simultaneously in/out of a desktop computer.
Boasting ultralow, round-trip latency down to three milliseconds, interoperability with all AES67 requirements, an embedded 128 x 128 switching matrix, Grandmaster PTP clock abilities, and high redundancy assured by two Gigabit Ethernet connections, the solution enables broadcasters to maintain performance regardless of computational load presented by other applications.
"As a leading supplier of audio-over-IP solutions for all applications and all budgets, Digigram will be bringing its full range of innovative IP audio codecs, audio applications, and professional sound cards to BroadcastAsia2014," said Philippe Delacroix, President and CEO at Digigram.
"We also look forward to showcasing our recently launched professional video encoder, which is a game-changer for live streaming applications."
