The Densité IP Gateway (IPG-3901) plug-and-play modules is a 3 RU module for the Densité 3 frame, which offers bidirectional IP/SDI conversion. The Gateway operates with 10 GigE audio/video video-over-IP, supporting 4K UHD/3G/HD/SD-SDI formats. The IPG-3901 v2.3 gateway module furthers the end-to-end support of IP for Grass Valley product lines от now offering support for Video Services Forum Technical Recommendation 04 (VSF TR-04), enabling independent routing of AES audio alongside SMPTE ST 2022-6 video and interconnection to audio devices supporting AES67 open standard for audio over IP.
With the addition of intoPIX TICO mezzanine encoding and decoding option on the gateway, customers have a convenient way to add 4K to their workflow and move 4K across the production facility. TICO mezzanine compression is visually lossless 4:1 compression, which is lightweight and fast, perfectly suitable for live production. The IPG-3901 with purchasable TICO option provides either two (2) encodes OR two (2) decodes OR one (1) encode and one (1) decode per card.
- Bidirectional transport of 4K UHD/3G/HD/SD-SDI video signal over 10 GigE port
- TR-04 support where each video signal is converted using SMPTE ST 2022-6 along with AES67 de-embedding/embedding of up to 16 audio channels per I/O
- Redundancy mode with full compliance of SMPTE ST 2022-7 Class A of all IP essences where each module connects up to 3×3 3G or 5×5 HD/SD signals
- Aggregation mode where both network ports are combined for a total IP bandwidth of 20 GigE:
- Provides higher 3G transmission capability per IPG-3901 card such as the transfer of 4K UHD uncompressed over a 4K link using a single IPG-3901 card
- In this mode, bidirectional I/O for 2 inputs, 2 outputs and 7 bidirectional I/Os for up to 11 streams
- Large frame buffer on every IP receiver provides support for server originated bursty sources
- All SDI outputs are aligned with respect to the module reference for precise timing adjustment ensuring signal stability
- Supports multicast loopback with SDI output alignment
- Support of PTP on the media port with fail-over redundancy for AES67 streams. Supports both AES67 and SMPTE ST 2059 profiles
- Support of DiffServ for network traffic provides categorization of flows into QoS classes
- Flexible SD/URS reference input
- Compatible with Densité 3 and 3+ platforms
- Integrates with iControl and GV Convergent SDN control frameworks
- IGMPv3 support for IP inputs
- Supports unicast and multicast signals
- Features dual-network interfaces supporting 10 GigE SFP+ with either:
- Short range multi-mode optical connectors
- Long range single-mode optical connectors
- Direct attach copper assemblies
- Active optical cables and optical transceiver
- TICO 4K 1-wire option:
- IPG-3901-OPT-TICO — this is a purchasable option that gives dual TICO codec option for 4K 1-wire support
- 2SI/SDQS 4K link I/O support as per SMPTE ST 425-5
- Simultaneous HD and 4K
- TICO is intoPIX Profile 1 with visually lossless 4:1 low-latency compression
- Flexible configuration of 2 encoder or 2 decoder or 1 encoder and 1 decoder
- 3G monitoring of 4K UHD signals
