Boosting SNG Via All-IP Networks - White Paper
- 1. BOOSTING SNG VIA ALL-IP NETWORKS
- 2. SNG or Satellite Newsgathering is an integral part of any broadcaster’s business. In our world of rolling news, sporting and live events the transmission of video from the scene has become essential, giving the feeling of immediacy, of being there. The last few years have heralded a significant change in the media and broadcast sector. Applications and technology are evolving, on a variety of different levels. The digitization of the sector has meant that the use of IP is overtaking more traditional means of broadcasting. This is a market in transformation and it’s an exciting time as more and more becomes possible. In the broadcasting world of today, a simple contribution link alone is not sufficient. Operators require access to the Internet, to file transfers, email and newsdesk applications. The effect of COVID-19 has also had an impact on the current broadcasting landscape in positive and negative ways. The requirement for people to stay at home has resulted in a huge rise in subscriptions for and overall usage of streaming services. This demand is creating congested networks and a struggle to serve some customers on overloaded terrestrial networks. On the other hand, the pandemic has negatively impacted outside broadcasting (OB), especially due to the lack of live sports broadcasts and newsgathering, as SNG trucks are parked up waiting for some sort of normality to return. The role of satellite in this transformation is going to be significant due to its innate and unique ability to deliver content to a large geographical area, anywhere on the planet and far beyond the reach of any terrestrial network. The satellite industry itself is also going through change as operators introduce new, High Throughput Satellites (HTS) that deliver more throughput, low latency services for less cost. Setting The Scene
- 3. The IP Evolution of Newsgathering Long gone are the days when a journalist would have to physically transport a tape back to HQ after covering a story so that it could make its slot on the evening news. Technology and digitalization has transformed OB and exponentially expanded broadcaster’s capabilities in the field. There are currently three methods of newsgathering used by broadcasters. Traditional SNG SNG is the use of mobile communications equipment for the purpose of worldwide newscasting. Mobile units are usually vans equipped with advanced, two-way audio and video transmitters and receivers, using dish antennas that can be aimed at geostationary satellites. Traditionally, newsgathering and sports coverage was handled by dispatching large trucks manned by various technically skilled people for each and every event. Each service had its own communication requirements. Bi-directional communication was often limited to voice using solutions such as ISDN. While these trucks had great coverage and could provide high bandwidth and availability, for many newsgathering operations they were simply too expensive to build and maintain and well as too large to get close to an unfolding scene. Cellular Bonding The industry then made a move to cellular bonding technology, which has become an increasingly popular choice for broadcasters. Utilizing 3G and 4G cellular networks to bring video back from the field, cellular bonding involves dedicated equipment and All-IP transmission. It is easy to use and enables broadcasters to get close to an event. However, cellular bonding relies upon bandwidth availability and if networks are contended, the overall quality of the transmission is negatively impacted. Blending All-IP Networks The next shift in newsgathering technology is occurring with the blending of all available IP networks. This eradicates the concern of degradation of transmission when relying on cellular bonding by ensuring that satellite is used when IP terrestrial networks are unavailable, do not provide enough bandwidth, suffer from jitter and are not cost-effective. In these cases, the system simply switches to satellite in order to create a highly reliable connection no matter where the news or event is breaking. Over recent years, there have been significant advances in satellite technology that offers broadcasters new means of delivering high-quality video. For example, Ka-band satellites offer higher throughput and can be used with smaller terminals that require less power than traditional the Ku-band satellites that are traditionally used on SNG trucks.

Trends Ingest Trends Advances in technology are transforming newsgathering and mean that for those covering the news, there are more options than ever available to capture footage. • Mobile Journalism (MoJo): For journalists themselves, the smartphone and tablet have brought about a paradigm shift in the way news is gathered. Portable electronic devices are now widely used to gather news, edit and distribute news. This means that a journalist must now be able to do everything. No longer is a team assembled with specialist knowledge. Each journalist must be able to bring together video, words and graphics to create their own broadcast. • Drones: The use of drones to capture footage for news outlets is on the rise. Drones enable crews to get to the story where they physically can’t and to give a different perspective on the news. This is especially useful for sports broadcasting and coverage of disasters. • 4K UHD: An increasing amount of transmissions are now being carried out using Ultra HD and therefore highly reliable, high throughput capacity is required. • Multicamera: Use of multiple cameras means garnering more high-quality content from more locations and perspectives. • IP Services: Skype and Zoom calls are also becoming a staple of the remote studio, especially due to the impact of coronavirus. However, they require sufficient bandwidth to ensure that these video applications run smoothly. Mobile Journalism (MoJo) Drones 4K UHD Multi-Camera IP Services
- 5. Production Trends The trend for remote production means that IP is essential for any newsgathering organization. An increasing amount of production is being carried out from remote locations without the standard technical infrastructure that would normally be expected. This is only set to increase with the increase of MoJo or mobile journalism and the use of multiple cameras. A great deal more editing must be completed at the remote studio to prepare for transmission. Transmission Trends The move towards IP means that broadcasters and service providers are now looking to aggregate IP bandwidth by bonding all available IP networks. To cover live news events, camera crews deploy mobile solutions that can transmit more than just video. They require access to multiple applications, including Voice-over-IP (VoIP), video clip transfer, web and archive browsing, email and social media, as well as newsroom applications. These all require a reliable bi-directional IP“multiservice”communication link of sizeable bandwidth to allow news crews to operate like they are in the studio. To aggregate enough IP bandwidth to concurrently handle all services a remote location requires, the specialist“cellular bonding” industry now bonds all available IP networks at a given point in time – whether it is 3G/4G, microwave, Wi-Fi, fiber, Ka- or Ku-band satellite. There are pros and cons associated with each method of transmission. However, the ideal scenario is to be able to shift to the most reliable and effective method when necessary. 3G/4G • Pros: Low cost, medium delay, abundant in urban areas • Cons: Medium throughput, uncontrolled bandwidth, bandwidth contention possible, susceptible to jitter, global availability Microwave • Pros: Low OPEX, low delay, high throughput, controlled bandwidth • Cons: High CAPEX, portability, low coverage area, flexibility of location WiFi • Pros: Very low cost, medium delay, abundant in urban areas • Cons: Very low throughput, uncontrolled bandwidth, bandwidth contention possible, susceptible to jitter Fiber • Pros: Low OPEX, low delay, highest throughput, controlled bandwidth • Cons: High CAPEX, low coverage area, flexibility of location Satellite • Pros: very high availability (Ka/Ku Band), high and scalable throughput, low jitter, All-IP, pricing is coming down (HTS) • Cons: satellite link delay, cost challenge High Throughput Satellites (HTS) Benefits for Newsgathering and Broadcasters The satellite industry itself is also going through change as operators introduce new, High Throughput Satellites (HTS) that deliver higher throughput, low latency services for less cost. HTS are changing both the economics and the entire user experience. New constellations are being announced or launched continuously, especially for new orbital architectures such as LEO/MEO. According to NSR, there will be 14 times more capacity by 2027. This is projected to drive down the overall cost of satellite capacity to spur new growth and is set to offer opportunities for broadcasters by making the environment even more favorable for future deployments.
