Audio Distribution Range

IQOYA *SERV/LINK Multiple-Stereo or Multichannel Audio-Over-IP Codec for Professional IP Audio Distribution

Digigrams IQOYA *SERV/LINK incorporates multiple distribution codec instances and the companys advanced FluidIP(TM) 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. Designed for radio broadcasting and for intercom and commentary for both radio and TV, 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 industrys 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 that provide uncompromising performance for IP-based studio-to-studio and studio-to-transmitter links, as well as audio program delivery to DVB operators. Developed in collaboration with major European telcos, the IQOYA *LINK/LE codec is a cost-effective version of Digigrams full-featured IQOYA *LINK codec that gives broadcasters the benefit of 24/7 reliability, audio format flexibility, ease of use, and affordability. Based on FluidIP(TM) technology, the smart IP audio streaming engine developed by Digigram, both IQOYA *LINK and IQOYA *LINK/LE boast high field-proven mean time between failures (MTBF), very low back-to-back latency, and a host of state-of-the-art features that guarantee audio quality and continuity. With audio synchronization 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. An intuitive Web-based user interface simplifies configuration, control, and monitoring and gives users access to real-time metrics on the network.

Video Distribution Range

AQILIM *FIT/LE Video Encoder

The AQILIM *FIT/LE professional video encoder is an intuitive and cost-effective solution for high-quality live event broadcasting over an IPTV network or multiscreen video distribution over the Internet. With flexible input options and compatibility with leading content delivery networks (CDNs), the encoder is ideal for popular 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 specialized 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 reliable low-latency IP audio contribution links while keeping costs under control. These codecs belong to Digigrams Mobile Studio and Ultra Mobility solutions, which bring professional quality to full-duplex connections between a remote site and a studio.

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 simple and straightforward usage in all outside broadcast situations.

IQOYA *CALL/LE is a cost-effective and versatile addition to the IQOYA range of IP codecs. It easily provides full-duplex IP audio sessions over the Internet and wireless connections thanks to its smart signaling and hassle-free symmetric RTP connection mode.

As with all IQOYA family members, IQOYA *CALL and IQOYA *CALL/LE codecs share the benefits of Digigrams FluidIP(TM) IP audio streaming engine, including smart jitter, packet loss and drift management; quality of service optimization; end-to-end dual-stream redundan
