Telos iPort High Density Multi-Codec Gateway

Telos® iPort is a Multi-Codec Gateway designed on an IP backbone that is used by broadcasters worldwide, featuring built-in resilience and reliability even with challenging connections. Worldwide networks use iPort for both Distribution and Contribution spanning multiple time zones.

Now, the iPort legacy continues with the more powerful iPort High Density, which transports multiple channels of stereo, mono, and dual-mono audio across IP networks, including private WANs, IP-radio links, and over good quality Public Internet connections—perfect for large-scale distribution of audio to single or multiple locations.

iPort High Density is the workhorse of codecs and comes with eight bi-directional stereo codecs, configurable to run in MPEG or Linear PCM mode.  You can license additional codecs up to a maximum of 64, as well as add Enhanced aptX™ encoding. iPort High Density connects to your existing Livewire® Network using a single ethernet cable (CAT-6 recommended) for all I/O. It can also pair with Telos Alliance xNodes via an adequately configured ethernet switch for use as a standalone multi-stream codec.

Coding algorithms include AAC, AAC-LD, HE-AAC (plus v2), MP2, MP3, linear PCM, and optional Enhanced aptX™. 24 to 320 kbps for MPEG codecs, standard fixed rates for Enhanced aptX™, and 24-bit PCM at 48kHz, mono, or stereo are supported. Dual, diverse-path, end-to-end connections are available for ultra-reliability and redundancy. Built-in streaming servers use SHOUTcast/ICEcast formatting at the output.

iPort High Density offers MPEG-standard ancillary data transport, up to three transparent control and metadata channels per codec and direction, and enhanced GPIO options with up to 20 end-to-end GPIO channels per codec and direction, all bundled and synchronized with the respective audio content. An optional Content Delay feature allows independent local storage and scheduled delayed playout of any or all coded audio channels.

• Transports multiple channels of stereo, mono, and dual-mono audio across IP networks

• Comes with eight bi-directional stereo codecs 

• Codecs are configurable to run in multiple MPEG or linear PCM modes

• Up to four redundant IP stream destinations per encoder

• Unicast UDP and TCP, or UDP Multicast stream types, independently configurable per WAN stream

• Each codec independently configurable 

• License additional codecs up to a maximum of sixty-four

• Enhanced aptX™ encoding optional

• Connects to existing Livewire® networks, allowing audio from remote facilities to be used as if they were local sources, with associated logic and control

• Pair with Telos Alliance xNodes and an adequately configured ethernet switch for use as a standalone multi-stream codec 

• Coding algorithms include:

• AAC

• AAC-LD

• HE-AAC (plus v2)

• MP2 (MPEG 1 layer 2)

• MP3 (MPEG 1 layer 3)

• Linear PCM

• Optional Enhanced aptX™ (24 and 16 bit)

• Supported bit rates include:

•  24 to 320 kbps for MPEG

For iPort High Density + Content Delay 

• Capabilities identical to iPort High Density 

• Adds hardware and exclusive software to enable delayed playout of selected received audio channels

• Associated GPIO and ancillary data are likewise delayed and synchronized with audio

• Each playback delay time is independently configurable on a per-channel basis

• The total amount of hours, bitrate, and the number of streams depends on storage
