A properly configured PTP clock is required to ensure all devices remain in sync. Switches used in an AES67 capable infrastructure should support DiffServ to provide correct prioritising of PTP and RTP packets. AES67 uses IEEE 1588-2008 Precision Time Protocol (PTPv2) for clock synchronisation. AES67 uses IEEE 1588-2008 PTP for clock synchronization of devices and prioritization of control and data traffic. The PTP V2 Priority values can be used to determine if your SMPTE-enabled Dante devices are more likely to be elected as masters or slaves. AES67 recommends that PTP takes the highest QoS Class 7, we recommend moving the RTP audio up above general traffic at Class 0. もしShureデバイス上でAES67を使用している場合、Danteプライマリリーダークロックとして選択したデバイスが、AES67 (PTPv1またはv2)のプライマリリーダークロックにもなります。 Jul 7, 2021 · PTP In Depth PTP is a network protocol developed by the IEEE which allows devices on an IP network to synchronize to a single Leader clock. Sonifex products use BMCA (Best Master Clock Algorithm) synchronization, which automatically selects the most suitable master clock for the network. Audio streams (both Q-LAN and AES67) must be the second highest priority on your network. Aug 29, 2023 · Hi all, I am trying to receive AES67 audio from other device and output it to I2S on a Pi 4B. AES67 also defines its own PTP profile, the Media profile. Is there any AES67 conversion software (to convert from a different protocol to AES67)? May 2, 2016 · AES Standards News Blog AES-R16-2016, Report on PTP parameters for AES67 and SMPTE ST 2059-2 interoperability AES and SMPTE have both specified profiles for IEEE 1588-2008 Precision Time Protocol (PTP) for use in professional media applications; the respective standards being AES67 and SMPTE ST 2059-2. Three profiles for Precision Time Protocol (PTP) might potentially be used in the professional media environment: the Peer-to-Peer Default PTP Profile of IEEE Std 1588-2008, the Media Profile of AES67 and the SMPTE Profile of SMPTE ST 2059-2. Nov 30, 2022 · The AES67 PTP media profile is based on the AES67 standard that is used for high-performance streaming and audio-over-IP interoperability in audio devices. AES67 provides the means for exchanging audio streams between areas with different networking solutions or technologies already in place, such as Dante, Ravenna, Q-LAN, Livewire, and WheatNet. Introduction AES67 is a published standard which defines interoperability guidelines for high-performance professional digital IP networking. May 10, 2021 · With IP, Precession Time Protocol (PTP) is leveraged to distribute time. AES67 mandates support of Differentiated Services (DiffServ), a QoS scheme where different types of traffic can be categorized into service classes. Check if PTP-aware switches are part of your network and try switching PTP support (temporarily) off. If all AES67 devices on the network support this profile (this is not a requirement), you can reduce the SYNC message interval down to 2^-4 – we recommend that you keep the SYNC message interval at the Media profile default value of 2^-3. Others are non-configurable. PTP media profiles SMPTE 2059-2 and AES67 are most commonly used profiles in the media industry. Excessive delay of audio packets over the network results in audio dropouts. Having both versions on the same network can be tricky. Dante Devices PTP Clocking Support The following table is a generic guide aiming to summarise the PTP capabilities of Audinate’s End User and OEM products. A node supporting AES67 shall tag PTP and RTP packets with different values which support priority settings for the data transport. ptp delay-req interval 0 (1 per second) is the default specified by the AES67 media profile. For details on how PTP works on an Ethernet switch, refer to this white paper on IEEE 1588 PTP on the Cisco Nexus ® 3100 Platform and 9000 Series Switches.
