Al Jazeera Supports Post-Earthquake Communication In Nepal

During a natural disaster, such as the 7.8 magnitude earthquake in Nepal on 25 April, communication infrastructure is often disrupted, and information can't get in or out of the affected region. For people in the area, and friends and family awaiting word of loved ones, news agencies often become the best place to turn for updates. Al Jazeera has been on-scene from the beginning, providing in-depth, up-to-the minute coverage and telling the story of the earthquake and its survivors.

To compensate for the loss of infrastructure, Al Jazeera has turned to satellite uplinks for reliable and high bandwidth transfer of video and data to news stations worldwide. One team is stationed in Kathmandu near Mt. Everest, reporting on the difficult conditions that is hampering rescuers abilities to evacuate climbers from the mountain. Vislink is proud to support Al Jazeera in their efforts to provide critical information to those that need it most following this tragic event.

Broadcast RF uses Vislink equipment to provide live coverage of the 2015 London Marathon


Broadcast RF chooses Vislink as RF solution supplier to ensure compatibility, versatility and quality coverage

When the 2015 London Marathon kicked off on Sunday 26th April, more than 38,000 participants crossed the starting line, making it the biggest in the event’s 35-year history. For the second year in a row, Broadcast RF was there with Vislink equipment to provide continuous live coverage of all 26.2 gruelling miles from Blackheath to The Mall.

To ensure top class coverage of every step of the course throughout the day, Broadcast RF and AMP Visual were relied upon by CTV OB (Outside Broadcast) and BBC Sport to provide the wireless live feeds for the event, which was viewed by a global audience of millions across 196 countries. The outside broadcast operation used a combination of fixed cameras at six OB stations, Vislink L1700 transmitters on mobile cameras, two helicopters and a fixed aircraft downlink from 22,000 feet, all linked to a central receive system at a master OB station positioned at Canada Gate.

“It was incredible to witness the dedication and organisation of Broadcast RF, AMP Visual and CTV OB throughout the days of hard work that went on behind the scenes. Vislink equipment was integral to the event coverage and is relied upon to maintain our customer’s professional reputation.”

Robert King,
Regional Sales Manager

Broadcast RF utilised Vislink’s 2GHz L1700 wireless camera-mounted transmitters, on five motorbikes that followed the route. Frequency spectrum is in short supply at the marathon, so Broadcast RF chose the L1700 for the MPEG4/H.264 video encoding that provides an excellent picture quality over the limited bandwidth. The L1700 is also lightweight and compact, making it perfect for mobile cameras where space and weight constraints are important factors. Vislink’s proprietary Deep Time Interleaving technology enhanced the robustness of the coverage, with its advanced system of error correction designed to cope seamlessly with interruptions to the link path that inevitably occur with this type of event coverage.

“With millions of eyes worldwide tuned into the event, it’s important that the operation runs smoothly. Having Vislink as an RF equipment supplier allowed us to build a customised solution for this event. We know that all equipment is compatible with the receiver facility, are in the bandwidth and frequency required, and offers the compression schemes needed to transmit quality images over the congested spectrum. We are always judged on our last performance and our reputation relies on having top quality equipment solutions, to ensure repeat business.”

Chris Brandrick
Sales Director
Broadcast RF

Stationary cameras at the OB station were complimented with handheld radio cameras using Vislink L1700s, which allowed cameramen to get down next to the runners and do interviews with fun runners, charity runners and celebrities alike. Two helicopter cameras were also deployed along the route, transmitting video feeds to a fixed wing aircraft circling the route at 22,000 feet. Two RF downlinks delivered the video from the aircraft at 3GHz via Vislink’s proprietary 24MHz wide LMS-T modulation scheme to a customised diversity receiver system at the master OB TV compound.

“We have worked with Broadcast RF for many years on a variety of events, and it was very exciting seeing their live coverage of the London Marathon. Vislink was pleased to work with the Broadcast RF Project Manager and engineering team to develop and support the best possible solution to ensure not a minute of the race was missed.”

TV Pro Gear Delivers The Future Of ENG Vehicles Vislink Microwave Equipment Included In Unique Vehicle Design

It looked like something straight out of a science fiction movie - a brand new, first-of-its-kind ENG news vehicle recently made an appearance at GISL-TV4 in Trinidad. TV Pro Gear designed and built the vehicle as part one of a phased approach to upgrading GISL's entire station to HD.

Vehicles over 33' feet are forbidden in Trinidad due to the tight winding roads. System integration company TV Pro Gear had to find a way to get the functionality of 40' truck in a 33' vehicle without sacrificing ergonomics and operator comfort.

President of TV Pro Gear, Andrew Maisner stated, "In the past, video recorders, routers and signal distribution gear required a large amount of equipment rack space. As technology has been progressing, the equipment has gotten smaller, less power hungry and less noisy. This allowed us to eliminate the machine room by putting all of the equipment in and under the production consoles. As a result, despite the reduced size of the vehicle, the main control room is still quite spacious."

GISL-TV4 will be using the truck to capture video from live broadcast sports, concerts and political events. Viewers will be able to enjoy HD quality broadcast images in real-time, thanks to Vislink's microwave transmitter atop the mast, and two repeaters strategically placed on area mountaintops.

"Vislink's sales and engineering staff were incredibly helpful in planning out the microwave transmission portion of this project. Their support ensured that the microwave system would be second to none."

From Scene To 4K Screen

Technology trends over the last year have travelled in the direction of bigger, better, faster and higher quality. We saw it with the growth of HD, and we are now seeing the same trend with 4K Ultra HD technology. There is no question that the future of TV viewing is 4K Ultra HD - consumers will continue to demand better picture quality and TV manufacturers will respond. 4K is the natural progression of technology advancement in relation to viewing monitor resolution. With four times the number of pixels per inch as 1080p60, images are clearer, more detailed, and of better clarity, and 4K televisions are slowly making their way onto the market.

Consumers are also demanding greater flexibility to when and how they watch television. Internet streaming of IP encapsulated video to televisions and peripheral devices has become a mainstream method of video consumption.

HD signals (1920 x 1080) are composed of 2 million pixels, while a 4K signal (3840 x 2160) is comprised of 8 million pixels. As a result, an important issue quickly becomes apparent: 4K has four times the resolution, and subsequently requires four times the amount of data to move video across the network, which quadruples the amount of bandwidth required to transmit when compared with HD.

The increased bandwidth required to transmit video at 4K translates to higher costs for cable and internet companies. At present, streaming HD content is already taxing network video traffic. As more and more videos are provided to viewers at 4K, the bandwidth required to stream the video will increase demand on cable providers, who may begin imposing bandwidth limits on consumers. This will dramatically increase buffering times for online 4K content viewing.

To counter this effect, engineers have been hard at work on better compression techniques that will reduce the bandwidth required to transmit data. Much like 4K is to next generation video, H.265 (also known as HEVC) is the next generation of video compression.

By employing advanced encoding techniques, and combining them with sophisticated modulation schemes, H.265 requires less bandwidth for transmission. H.265 is expected to deliver the same, or even superior, picture quality for both HD/SD and 4K resolutions, at up to a 50 per cent reduction in bitrate versus its predecessors, MPEG-4/H.264. There are a number of microwave transmission technologies that can be used to compensate for the remaining 25 per cent of additional bandwidth.

For example, in point-to-point microwave or satcom applications, DVB-S2X (DVB-S2 with extensions) enables steeper roll-offs in the modulation scheme enabling more carriers to be squeezed into the available bandwidth.

Also, for non line-of-sight MIMO (multi-input multi-output) OFDM transmission techniques can be used to increase throughput by utilising multiple antenna techniques with antenna de-correlation to create two independent video streams.

Other improvements can be achieved using LDPC (low density parity check codes) FEC techniques can alternatively be used to help offset the additional 4K bandwidth. LMS-T modulation techniques with LDPC codes increases data throughput for a comparative signal to noise ratio.

Additionally, LTE technology, as used in 4G cellular transmissions, can be utilised in private frequency bands for local networks.

To make way for broadcasting 4K efficiently and cost effectively, encoders and decoders will need to incorporate H.265 compression schemes. There is some debate over the timeline of implementation and adoption, but some equipment manufacturers are already developing encoders with H.265 compression capabilities.

Much of the focus has been on last mile delivery of video (ie, to playout devices via IP or cable). However, H.265 will also play an important role in the collection of video from the field, as better compression and modulation schemes will result in lower bandwidth requirements for broadcasters. For example, the impact on cellular newsgathering would be beneficial. Right now, cellular transmitters can stream in HD, but with H.265, they would be able to deliver the same quality video at half the bandwidth, lowering the cost and improving the quality of transmission.
