挑战

With the recognition that more OBs would require UHD capability along with a fully IP end-to-end workflow, in 2016, Timeline Television began examining the possibility of building a state-of-the-art, triple expanding OB truck to support fully uncompressed 4K/UHD, IP and High Dynamic Range workflows. The truck would be based around the SMPTE 2110 and SMPTE 2022 standards that define transport and timing protocols for audio, video and metadata over an IP network. The design would use a number of elements from broadcast technology supplier SAM but when it came to core IP switching, the choices were limited as Dan McDonnell, Managing Director and Founder of Timeline Television explains. “We needed a high density switch with 100G ports and support for 4 lanes of 25G with nonblocking architecture as unlike a data network, we can’t drop any packets. If you look at the market, that rules out the vast majority of vendors and in our test the Arista 7504R was able to handle everything we threw at it”

解决方案

The Arista 7500R Series modular systems are high-performance data center switches, available in a compact 7RU (4-slot) or 11RU (8-slot) that combine scalable L2 and L3 forwarding and traffic management with advanced features for network monitoring, precision timing, and network virtualization to deliver deterministic network performance for mission-critical data centers, cloud computing, enterprise, and HPC environments. The 7504R has 36 x 100G Interfaces per line card with a switching capacity of 15Tbps plus an industry-leading latency of sub 4 microseconds. With the Arista switch at the heart of the system, the OB truck has an effective maximum matrix size of 4608 x 4608 which allows it to run 32-cabled Sony 4300 cameras plus 14 UHD capable video servers along with full audio up to Dolby Atmos levels. The truck, which took 5 months to build, is widely regarded as the most advanced unit of its kind in Europe. As McDonnell says, “As an industry first, there was a bit of a learning curve, but we had no issues with the Arista switch. One of the things we were concerned about was unlike a data center where a switch is always on, we have to deploy on a new site for every job and switching equipment on and off needs to be predictable and have reasonably quick startup - in this respect, the Arista switch is up and running in under 8 minutes which is faster than some of the other elements within the truck.”

The new UHD truck has already been put through its paces at a number of high-profile events including the recent IAAF World Championships and World Para Athletics Championships in London.
The truck is regarded as the most advanced unit of its kind in Europe, showcasing the state of the art in terms of outside broadcasting technology.
The Arista switch provides flawless reliability, ensuring real-time operation with its sub 4 microsecond latency.
The small form factor of the Arista switch allows for flexible deployment of 10, 25, and 100G interfaces to meet every deployment scenario and future evolution.
