The IQMIX25 is a multichannel video-over-IP transceiver developed for use within low latency and high bandwidth Ethernet IP networks. Using RTP VSF TR-03 (SMPTE ST 2110), TR-04 and SMPTE ST 2022-6 encoding and encapsulation schemes, along with either clause 74 or clause 108 FEC, enables the IQMIX25 to encode or decode up to 16 SDI signals and transport them over redundant 25 GbE links (SMPTE ST 2022-7).
IQMIX25 provides frame synchronized SDI outputs along with both compressed and uncompressed modes of IP operation. Using SMPTE ST 2042 (VC2) lightweight compression allows for high quality signal carriage whilst optimizing bandwidth requirements, and sending signals uncompressed provides best quality transport although at the expense of bandwidth. Encapsulation of signals in a SMPTE ST 2022-6 transport stream provides compatibility with other video over IP solutions.
IQMIX25 fully integrates with remote control and monitoring systems to provide easy set up and real-time information on signal presence and status for each channel. It’s also fully compatible with Grass Valley’s new broadcast-centric IP routing and network management solution designed to migrate broadcasters from a traditional baseband routing and control environment to new hybrid SDI and IP workflows.
Handles up to 16 SDI signals over dual 25 GbE IP links (dependent on SDI signal format and compressed or uncompressed transport mode)
Supports configuration of Ethernet links for maximum signal transport using both SFPs or for dual link mode to provide link redundancy as per SMPTE ST 2022-7, and when operating as a receiver will dynamically adapt to any stream presented to it
Multiple transport types available for each SDI input including:
Compressed IP transport using SMPTE ST 2042 (VC2) low latency high-quality encoding profile
Uncompressed video transport using either VSF TR-03 (SMPTE ST 2110) and TR-04 RTP, or SMPTE ST 2022-6 encapsulation
PCM audio using TR-03 & AES67
SMPTE ST 2110-40 metadata support via IETF standard “RTP Payload for Ancillary Data”
Supports frame synchronized SDI inputs and outputs referenced to either IEEE-1588v2 (PTP) network timing (compliant with SMPTE ST 2059-2) or via the IQH3B or IQH4B frame’s analog reference bus for Black Burst / tri-level syncs
Includes UHD quad link mode for 3G SQD or 2SI signal transport
Supports unicast as well as IGMPv3 source specific multicast, allowing point-to-point operation or transmission in multicast groups, and forward error correction with either clause 74 (Base-R) or clause 108 (RS) FEC
Low delay mode and Independent H & V offset available for each channel along with up to 2 frames of video delay, and up to 255 ms of audio delay
3G-SDI to SMPTE ST 424/SMPTE ST 425 level A compatible
HD-SDI to SMPTE ST 292/SMPTE ST 274/SMPTE ST 296
