MediaKind Cygnus Contribution
This media processing and delivery solution addresses a number of different live content contribution use cases and applications such as remote / at-home production with distinct values enabling content providers/owners, Broadcasters and TV Operators to maximize their investment whilst maintaining the quality and low latencies required for professional media delivery.
Aperi Network Address Translation (NAT) & Firewall App
App Store. Providing seamless inbound and outbound re-routing of RTP streams within your network infrastructure, NAT app also includes RTP stream health monitoring, which will automatically shut down streams that deviate from a specified policy. Stream replication allows for two distinct output streams with independent IP addresses, ports, and VLANs. Failover can merge multiple source streams, selecting the highest quality single stream and automatically switching to a perfect replication should the
original stream degrade in quality or deviate from policy. The supports the SMPTE 2022 standard for transporting both compressed (2022-2) and uncompressed (2022-6) media flows via IP. NAT app provides an open bandwidth budget across the 10 GbE interfaces, and can route varying numbers of compressed (2022-2) streams depending on size, and up to 6 uncompressed (2022-6) streams per SFP port. It also provides support for the SMPTE 2110 standard, and can route video (2110-20), audio (2110-30), and ancillary data (2110-40) flows independently through networks. NAT app provides an open bandwidth budget across the 10 GbE interfaces, and can route up to 64 independent media flows per port. It offers stream duplication for media flows via SFP, and A/B failover for flows outputting through SFPs.
4-layer inspection for basic ACL:
Ethernet: mac.dst, mac.src, vlan, vlanid
IP: ip.dst, ip.src
UDP: udp.dst, udp.src
Additional inspection of RTP payloads for ACL
Ensure 2022-2 payloads conform to transport stream structure and have correct packet count
Ensure 2022-6 payloads include RTP header extension, SDI types in headers match configured values, and detect if frame size of encapsulated SDI matches configured value
Ensure presence of RFC4175 payload header and indicated frame size matches configured values; ensure encapsulated raster video frame size matches configured value
4-layer packet header rewrite enforces complete re-addressing of every packet before egress
All unicast/multicast mappings are supported
For multicast flows, flood, IGMPv2 and v3 are supported
Monitoring and Stats
Ingress statistics include:
Ethernet: Frames received, FCS errors, packet rate, and total average bandwidth
Firewall-overall & firewall-per-flow counts total packets dropped, accepted, average speed and bandwidth
RTP flow shows RTP type (and payload header if applicable), sequence number, transport stream checking, and PDV/inter packet arrival time
For 2022-2, shows TS packets per payload, TS lock, TS rate, and payload alignment
For 2022-6, shows SDI type indicated by payload header versus one detected by line/sample counting, and SDI TRS lock and errors
For RFC4175, shows video raster type indicated by payload header versus type detected by line/sample counting
Egress statistics show total packet count, packet speed, and average rate per flow and for Ethernet
Configurable PDV buffer depth
Creates a new regenerated hitless transport with new addressing
Counts total number of recovered and unrecoverable packets, along with the differential delay between input flows
Designed for IP-centric operations:
Specifically designed for IP-centric operations, the X10 and X20 chassis has a significant video processing capacity. 10G bi-directional IP interfaces provides video firewall-grade IP security at every connection node. Capable of internal routing of up to 140G, the backplane extends Appear’s tradition of providing high capacity future-proof platforms. The chassis supports dual active backplane providing Appear TV patented lossless redundancy between modules. Service density can be defined up to 2,000 services in and out per module.
Current and future IP video standards:
The X platform supports “light” intra-codecs as well as AVC and HEVC. Option modules for receiving compressed or uncompressed video from IP or SDI (Optical and Electrical) are readily available. With backplane latency of less than 1ms, universal applicability for virtually any video application is ensured, as is the implementation of both current and future IP video standards, including VSF-TR03, VSF-TR04 and SMPTE2110.
X Platform Modules:
Hi-density, modular and hot-swappable - the X10 and X20 use the same set of modules and same software:
Software-based Video Compression
With high performance H.264 and H.265 encoders as our core component, services can be transcoded into multiple profiles up to UHD with HDR. Encoding quality levels can be chosen to achieve desired quality vs. speed, making it possible to target a large number of different requirements. Running on COTS servers and supporting IPTV, OTT and VOD applications, all screens become picture perfect.
Live transcoded services can be streamed out as key-frame aligned transport streams straight into Appear ABR or any existing packager and origin server. Alternatively, HLS segments and playlists can be generated directly, ready to be fed into existing CDN infrastructure. For VOD the easily configurable architecture and RESTful API allows for integration into any workflow.
Key features include:
- High Quality H.264/AVC and H.265/HEVC transcoding
- Automatic resource allocation with centralized management
- Flexible redundancy schemes
- MPEG TS, HLS and SRT output
- Pure CPU solution running on COTS
- Different CPUs and server configurations supported in same cluster
- GOP alignment between servers for optimal hardware usage
Limelight Live Push Ingest
Limelight Video Delivery
LiveU Matrix offers cost-effective and reliable live content distribution over the public internet with significant cost savings compared to traditional contribution and distribution methods. Only minimal infrastructure is required to set up new content sources and destinations – allowing you to replace SAT dishes and IRDs with backpacks, rack-mount encoders and servers.
The dynamic cloud platform makes it simple and cost-effective to curate content through one interface. Users can easily search, filter, preview, and distribute live feeds to one station, multiple stations, or thousands of end points within their entire network. The flexible interface can also be customized based on the user’s role. LiveU Matrix gives full visibility into all feeds available and puts the broadcaster/production crew in the driver’s seat to manage and send content anywhere.
Used by tier 1 broadcasters and leading content creators worldwide, Matrix has been built from the ground up to support well-established content sharing models with intuitive, broadcaster-oriented modes of operation. These include large affiliate networks or press agencies, media/ownership groups, national broadcasters as well as smaller local loop or event pools, and local/global content syndicators. Major news broadcasters including CBS, CNN, Cox Media Group, Fox Sports, Meredith Corporation, Quincy Media, and Sinclair Broadcast Group are curating their content with LiveU Matrix. During the COVID-19 pandemic, governors in several US states are also using LiveU Matrix to deliver their daily live briefings directly to stations and networks from remote locations.
