Frequently Asked Questions

  • What makes LTN unique?

    LTN Global operates a fully-managed private terrestrial network accessible from anywhere in the world. Our patented network protocols enable broadcasters to transmit live feeds with complete confidence. We guarantee 99.999% uptime and latency, better than satellite, fiber, or other legacy forms of live video transmission.

    The core of our network is highly redundant, using multiple Tier 1 internet backbone carriers and secure global data centers. Our proprietary rapid error recovery (RER) and dynamic multi-carrier routing (DMR) technologies instantly detect and correct even the slightest interruptions without the need for human intervention. LTN DMR ensures uninterrupted feeds even in the face of complete failure at one or more carrier networks or data centers.

    Once connected from any point on the internet, our clients can access any other authorized broadcaster in the LTN Network. LTN offers 24/7/365 monitoring and client service through our network operations center (NOC), staffed by trained operators who respond immediately when human intervention becomes necessary.

  • Which security measures do you have in place to protect my content?

    Content access is strictly controlled to support our clients’ requirements and provide best-practice security. Each client determines which destinations will have access to its transmissions for full-time feeds or occasional-use events.

    LTN utilizes multiple layers of protection including a fully managed service, which only activates feeds to authorized receivers as specified and scheduled by each client through the LTN Portal. The portal protects content integrity, produces a transparent audit trail, and utilizes both end-to-end and individual-access-link encryption.

    Secure access to the LTN Network is flexible and easy to manage. As your operation evolves, our 24-hour network operations center will assist in granting or removing access as required.

  • What are the membership benefits of the LTN Network?

    LTN is a secure, lightning-fast network of more than 3,000 client sites across the globe, with new broadcasters, sports venues, studios, full-time channels, cable head-ends, digital platforms, and events connecting every day. Content providers can transport point-to-point or point-to-multipoint broadcasts, and broadcasters can schedule and accept feeds in seconds.

    LTN Network members can easily receive contribution feeds from or distribute content to any other member, reaching linear and digital destinations quickly and easily. The LTN Network accepts, converts, and delivers MPEG-TS feeds and digital streaming formats like HLS, RTMP, and MPEG-DASH.

    Clients can send and receive short- and long-form events or full-time channels over the LTN Network. They can choose to quickly add or cancel a destination for any reason at any time.

  • How do you guarantee performance?

    Our managed network includes diverse carriers in all of our data centers. In the unlikely event that a data center or a carrier were to fail, we would automatically reroute any channel or feed through alternate paths and carriers in milliseconds. We extend our multipath technology and fast rerouting to each client’s “last-mile” access and can leverage multiple ISPs at a client site to provide the highest guaranteed availability of any transport service in the world.

    This performance guarantee is spelled out in our service level agreements.

  • Can LTN provide linear and digital transport of my content?

    The LTN core broadcast network delivers any MPEG-TS transport stream unmodified to any number of receivers. LTN can encode and decode feeds from and to SDI with our LEAF integrated encoder/decoder or with third party encoders.

    We seamlessly transport large, pre-encoded, and MUX’d channels with existing encoded signals to prevent additional encoding costs. IP/TS transport without encoding or decoding requirements can be managed entirely on LTN appliances, which are available at any LTN-installed location.

    LTN provides digital transcoding, transport, and delivery of any channel to streaming destinations and OTT platforms. The LTN Network has integrated world-class video transcoders to provide any digital format required by our clients, from RTMP to DASH. We also can provide efficient scaleout streaming delivery for large-scale distribution through our integrated partner CDNs.

  • Is LTN available around the world? Who can I connect to?

    The LTN Network is available globally and is actively used on all continents except Antarctica. LTN connects several thousand client sites with hundreds of live-shot studios, TV stations, sports venues, broadcast facilities, production houses, and content distributors all in one easy-to-use platform. We provide clients anywhere in the world with an accessible and secure connection to everyone they want to reach, including all major broadcasters and streaming platforms.

  • How do I connect to the LTN Network?

    Connecting LTN equipment to the internet is all you need to access the LTN Network. Our unique technology enables connection to and from any site in the world, including large data centers and major broadcast networks with multiple carriers, single studios with one ISP, the portable LTN Flypack™, and temporary facility networks like hotels and convention centers. LTN fully supports diverse connections with multiple ISPs to remove any single point of failure and increase the availability of the network.

    LTN also supports direct fiber cross-connects at major data centers, interconnections with other transport services like LiveU, direct managed public cloud access, private peering connections, streaming protocol ingest and delivery, and even interconnections with traditional fiber networks and satellite teleports.

  • Which codecs and video formats are supported by LTN?

    Any broadcast format that can be transmitted in a transport stream will work on our network. LTN regularly carries channels ranging from SD and HD to 1080p60, 4K, and 8K signals. Any codec that is compatible at both the sender and receiver can be used, whether traditional MPEG2 and H.264 or newer JPEG2k and HEVC. LTN does not modify the transported signals, so even content-owner encrypted signals can be transported easily without LTN requiring any special access.

  • How do I book and manage my feeds?

    For full-time feeds, there’s no need for scheduling. The LTN NOC provisions your channel and ensures it is delivered to all of your authorized destinations, whether a single party or hundreds of receivers. For scheduled events and occasional use (OU), our simple web-based portal enables you to schedule your feeds in seconds. Whatever content you choose to route into any LTN OU endpoint can be delivered on a point-to-point or point-to-multipoint basis.

    LTN also operates a 24/7/365 network operations center, which directly helps clients with any questions about their feeds.

  • How does LTN work in public cloud environments?

    LTN has extended our IP video transport network into many public cloud environments, including AWS and Microsoft Azure, consistently guaranteeing the same broadcast quality, ultra-low latency, and service levels of our physical network. Clients can book feeds into and out of public clouds and manage physical transport paths through the same LTN Portal. LTN transport services can peer with client virtual networks or integrate directly with a client deployment of playout or video processing services.

  • Does LTN have support for ancillary and meta-data services?

    As LTN does not modify the TS signal, we can transport any data in pre-encoded signals. For SDI-to-SDI transport, LTN encoders and decoders support many types of captions, SCTE triggers, and other VANC data in accordance with standards-compliance.

  • What is the LTN setup process and timeframe? How do I get onto the network?

    The process varies depending on project size and type. During discovery, we work with clients to confirm the technical requirements, video equipment compatibility, and adequate bandwidth availability at all sites. The LTN engineering and sales teams support this process through technical discussions and by leveraging our existing relationships with vendors, carriers, and partners to find the optimal solution for each project.

    For simple installations—such as some studios or single LTN appliances with an existing ISP—equipment can be configured and shipped within two days of a completed order. Once the client has received the equipment and it has been installed onsite, we conduct a 24–48-hour network verification test to ensure all video services will be reliable. Sites are released to production following successful network and video testing.
