News Gathering (ENG)

For news networks and stations, LiveU's live broadcasting equipment transforms the digital video acquisition chain into an agile workflow of news gathering. It offers a portable, highly robust uplink system for SD or HD-quality coverage of breaking and local news, and opens multiple opportunities for new types of reporting, for example:

- Live weather and traffic reports from fast-moving vehicles, such as cars, trains, motorcycles, boats, and even helicopters.

- A single reporter or camera operator, outfitted with a video camera and a LiveU backpack, can be dispatched to perimeter areas of an unfolding story to interview eyewitnesses and passersby, cover other emerging sub-plots, or provide live ‘beauty shots’.

Live Sports

LiveU is the perfect complement to live sporting events, providing a mobile, on-the-spot solution for quick updates, sideline and locker room interviews, crowd shots, pre and post game shows, press briefings, roaming cameras at team events and media days, and more. Broadcasters are also utilizing LiveU for transmitting live games and competitions online, as well as to stadium jumbotrons, and more.

Entertainment

LiveU customers regularly utilize the video broadcast equipment for entertainment events, such as red carpets, premiers, live reality shows, fashion shows, hometown live shots on talk shows, and celebrity coverage. LiveU offers easy live content acquisition to live in-studio TV shows that rely on feeds from the street or remote locations to augment their programming.

Pre-Recorded Upload

Even if you don't require a live feed from the field in every instance, LiveU is ideal for preparing footage on the fly. Edit a take and add graphics in the field on your laptop and then uplink the finished file via FTP utilizing the multiple modems of the LiveU system. Also, you can easily upload large amounts or raw footage for studio editors to process.

Technology

Overview

cellular video link

LiveU is a pioneer in portable video-over-cellular technology, addressing all demands for full HD or SD quality, resiliency, availability, mobility and sub-second latency in a highly innovative technological solution. Our core technology is based on cutting-edge adaptive algorithms which combine cellular communications and video encoding.

LiveU holds the patent (US Patent No: 7,948,933) for its Remote Transmission System.

The LiveU solution bonds up to 14 cellular (3G/4G LTE/WiMAX) modems over multiple carriers, as well as multiple LAN and even BGAN satellite connections. This creates a reliable, broadband video uplink pipe over multiple narrow-band pipes. Using any camera, the fully-integrated self-powered compact unit provides video resolution ranging from CIF through D1 (SD) and up to 1080i HD. The bonded 3G/4G solution aggregates all data connections simultaneously to achieve high bandwidth and smooth transmission, even as bandwidth and signal levels change across the different connections.

LiveU was the first company to integrate 4G LTE links into its cellular-bonding solutions. Since September 2010, LiveU mobile transmission solutions have been deployed in several commercial LTE networks, such as in Scandinavia and the US. While single modem video delivery devices might suffer from performance fluctuations, loss of transmission or inability to go live, LiveU's multi-link solutions allow broadcasters and online video professionals to enjoy the benefits of both the 4G and 3G worlds. LiveU's solutions are considered to be a viable alternative to costly satellite uplink or portable satellite TV equipment.

LiveU's video uplink systems meet US and EU cellular health-related standards (i.e. SARs - Specific Absorption Rates). For more details, please contact us.

High Quality Video Transmission

LiveU has developed several advanced proprietary algorithms that enable resilient high quality video transmission over the ever-fluctuating multiple cellular networks. Among these are:

• Adaptive Bit Rate (ABR) of the H.264 video encoder.

  • This mechanism adapts the video encoding rate continuously according to the changing network conditions. Taking into considerations the continuous real-time measurements of the performance of every available link, the user’s resolution and latency requirements, cellular channel behavior and other parameters, ABR reduces or increases the H.264 video encoding rate. The result: a real time video rate adaptation mechanism that optimizes the encoding process on-the-fly.

• Error handling mechanisms:

  • In wireless and cellular environments, packet loss and errors are common inherent phenomena. LiveU has been developing proprietary error-handling mechanisms specifically adapted to these phenomena and to the unique paradigm of aggregation of multiple links. Adaptive and predictive Forward Error Correction (FEC), Error Concealment and Error Recovery mechanisms at the video application level complement each other and are employed as needed for each specific operation conditions.

LiveU provides sub-second latency for interviews and highly resilient profiles for live transmission from fast-moving vehicles (cars, trains, motorcycles, boats, and even helicopters when local law permits). We also offer high-speed File Transfer mode (FTP) over the aggregated bandwidth. As part of its full service option, LiveU providesroaming support for cost-effective global coverage.
