High-definition necessitates high requirements
While live tv and news broadcast events might be synonymous with the images you’ve seen of rows and rows of satellite trucks, the truth is that a growing number of these live video transmissions are broadcast over cellular networks. The value proposition is clear: done right, live broadcast transmission on cellular networks offers a compelling combination of mobility and bandwidth for broadcasters.
However, done wrong, live broadcast over cellular can be fraught with out-of-control costs, connections that go down at a hint of network congestion, and insufficient latency for live broadcast requirements.
A leader in video contribution uplink systems over 3G and 4G cellular networks, French Company AVIWEST makes it their mission to equip live video organizations with the right video equipment to do the job.
Creating an industry-leading solution with IoT
Part of the requirements of that mission is to develop and supply market-leading technology to customers in this competitive and fast-moving industry.
“There may not be any mobile broadband application quite as ‘broadband’ as live transmission of HD quality video streaming; Data rates are massive and thus transmission costs and latency are of significant consideration. We always strive to reduce this cost for our customers.”
– Ronan Poullaouec, CTO AVIWEST
AVIWEST sought to provide a remote video uplink system that offered a superior combination for highly mobile live broadcast crews: small size, high efficiency, and powerful video throughput.
Finding the Right IoT Partner
To provide an industry-leading product in terms of footprint, battery life, video quality, and transmission costs, AVIWEST decided to work with Telit to leverage the superior performance of a well-designed cellular module. Including up to eight of these cellular modems as the foundation of the product meant AVIWEST required confidence in the cellular modems ability to perform amidst high data transfer rate requirements across any place in the world.
The PRO 3 series video encoders and transmitter, the flagship model of AVIWEST, is designed for live video producers and news gathering professionals looking for industry-leading performance from any location around the world. Special proprietary encoders compress video data streams, decreasing the cost to transmit by up to 30%. The 8 3G/4GLTE modems are coupled with a patented custom antenna array for optimal signal strength.
“The Telit LM940 and Telit LN940 modules met all of our demands, exceeding other module offerings on the market in terms of reliability, performance, and worldwide coverage on a single module. We expect a dramatic increase in battery life for our product due to the implementation of this module.”
- Ronan Poullaouec, CTO AVIWEST
Telit’s high-bandwidth, high-category cellular modems offer radio frequency performance that AVIWEST can count on. The industrial-grade PCIe M.2 form factor allows for easy integration in our products and the global-compatibility of these modules ensures AVIWEST’s global go-to-market plan can develop with minimal SKUs and manufacturing concerns.
“The global nature of the cellular modules allows us to minimize operation costs. It allows us to really focus on growing the competitive nature of our business as opposed to controlling the costs of operating this network of devices.”
- Ronan Poullaouec, CTO AVIWEST
While the PRO 3 series stand as industry-leading solution in terms of cost savings and quality of service, the AIR series focuses on being an ultra-compact cellular transmitter to bring live broadcast events to the masses. This back-pack portable solution is enabled by highly-efficient cellular data cards; battery life is an important consideration in such a small package.
Automatic processes including adaptive clocking, selective suspend, link power management, and more combine with the powerful AVIWEST proprietary video encoding system to keep video streams transmitting efficiently.
