Co z AES67?

AES67, formaly known as AES67- 2018 (and originally AES67- 2015), is a standard for thee transporty of high--quality audio over IP networks. It specifies a set of procoms and formats that ensure audio signals can be exchange reliable between devices from different different dirers. At its core, AES67 desites the use of thee Real- time Transport Protocol (RTP) for streg audio, thee Session Initionion Protocol (SIP) foreconneconnection management and streation, and the precisisin Timol (Ptvv2, Iene), Iene exentárt entárt entárörört.

Porównania AES67 wigh Other AoIP Standard

AES67 is note only AoIP standard on thee market. Competeng technologies included Dante (Audinate), Ravenna (ALC Network), Livewire + (Thee Telos Alliance), and SMPTE ST 2110-30 (a professional media standard). Understanding these differences helps integrators choose the right tools for their intercom systems.

  • Dante: Proprietary but dominant in the pro- audio exterd. Dante implements AES67 as an optional disability mode, allowing Dante devices to exchange audio with non-Dante AES67 gear. Dante 's nativa protocol offers lower latency andd easyr discvery, but AES67 mode occupes some compatiures for compatibility. Many intercom conterrers now include both Dante and AES67 modes.
  • Ravenna: Developed by by ALC, Ravenna is also based on RTP and PTP and is fully compatible with AES67. It adds advanced factores like high-density multichannel transport andd sulfrant streams. Many broadcast contrirers, such as Lawo andd Neumann, use Ravenna in their products. Ravenna is often preferred in large- scale broadcast plants that require many channels.
  • SMPTE ST 2110-30: This is the widdact industry standard for transporting uncompressed audio in professional media environments. It use the same RTP and PTP foundations as AES67 but adds requirements for video synchization and timing. AES67 can be considered a subset of ST 2110-30; therefore, intercom systems designed for ST 2110-30 networks are often AES67-compatible. As transmissters transition to IP- based production, ST 2110 appolettion is acceletating.
  • Livewire +: Te telos Alliance 's AoIP ecosystem is used d widely in radio. Livewire + equivates AES67 support, enabling connectivity with IP audio codecs and third-party intercoms. It also offers publicary providenges like automatic straint routing andd integrated phone system integration.

For most intercom applications, AES67 provides the beset balance of difficability, performance, and coste. When a faciliy is committed to a single vendor 's ecosystem, the nativa protocol may offer faciligages, but AES67 ensures that no device becomes an island. For new installations, choosing equipment that supports AES67 as a primary or seconsecondary transport metod is a safe long- term strategy.
