One of the most critical challenges for broadcasters today is arriving first on the scene of a breaking news story and being able to send live video coverage. Tough competition between TV channels, combined with the fact that consumers are demanding news faster and on multiple devices, means that broadcasters must have reliable, cost-effective, and portable video uplink solutions at their disposal.
Flexibility is especially important today. As the number of available networks continues to grow, broadcasters need to be prepared for any situation. Choosing a system that supports a wide range of networks, including 3G/4G cellular/wireless, WiFi, Ethernet, and satellite will guarantee that a broadcaster can air live news from any location around the world.
Ease of use is also important and will enable a news organization to react to breaking news. A video uplink system that has been designed with the user in mind will include features like automatic recognition technology, which detects real-time network capabilities and bonds together multiple IP-based networks, as well as a touch-screen interface for simplified configuration and operation.
Additionally, for larger news operations, the ability to monitor and manage an entire fleet of digital mobile newsgathering equipment is an extremely advantageous piece of cellular bonding. Haivision’s new DMNG Manager, was launched at IBC2014. It is a live video contribution platform that enables control over a wide range of equipment including DMNG transmitters, smartphones using the DMNG APP, and DMNG Studio receivers, allowing broadcasters to easily allocate resources and route live video content for transmission over 3G/4G cellular wireless, WiFi, Ethernet, and satellite networks. By streamlining DMNG operations, the solution provides broadcasters with significant time and cost savings.
Being able to maintain a high video quality from remote corners of the world can be challenging, but not impossible. It requires mastering three types of technologies. The first is network bandwidth. Broadcasters can get the most amount of bandwidth by bonding together all available networks, such as WiFi, 3G/4G, and satellite, and then adapt the video compression according to those available networks, in real-time. The second technology that comes into play is video compression. Advanced video compression technologies (e.g., H.264 and next-generation standards like HEVC) and pre- and post-processing tools (e.g., filtering, video concealment process, etc.) are needed to reduce the required bandwidth for a given video quality level, and improve the quality of experience for viewers. Finally, video contribution is key. The transmission must be robust in order to handle possible errors and packet loss. FEC and packet retransmission are the most common features to implement to improve transmission reliability.
