将现代技术与视频管道相结合, 桥的数字 develops affordable turnkey solutions and provides services that streamline video capture and manipulation for clients around the world.
而内容创作和交付的趋势也在不断变化, the quest for greater workflow efficiency has remained constant, 这是一种努力 桥的数字 has helped its customers pursue since opening its doors nearly 20 years ago. 将现代技术与视频管道相结合, its 10-person team develops affordable turnkey solutions and provides services that streamline video capture and manipulation for clients around the world. Each system that 桥的数字 develops is tailored to suit the client's needs, 包括它的最新作品, 4K HEVC编码解决方案 Aja kona 5 8通道PCIe 3.0 I/O卡，NVIDIA显卡，和 激烈的 Technologies的Net-X-Code 用于IP捕获、控制、转换和输出.Originally developed to package fitness classes for on-demand viewing for one of 桥的数字’s clients, the solution prepares live 4K streams for 4K video-on-demand (VOD) delivery with little to no downtime. 它产生一个精确的帧, 每个类的高比特率HEVC代理, 哪些操作人员可以很容易地夹和修剪, 基于代理时间码, as the file is recording using the Net-X-Code interface in an HTML5 web browser. 用不同的班级拍摄成一个长录像, the client can easily identify and pull classes as they end without stopping the recording. A future-proof tool, 桥的数字’s solution also supports up to 8Kp30.
“实现一致的, high quality look across live and VOD assets was crucial for this implementation. 以4K作为选择的采集格式, we knew HEVC was the way to go to ensure more rapid turnaround and delivery to the VOD library once each class had wrapped,里奇·默里分享道, 总裁兼创始人, 桥的数字. “HEVC delivers a high quality picture with a low bit rate and more manageable file sizes compared to alternative video codecs. 具有创造性思维, 以及AJA的帮助, 激烈的, 和NVIDIA技术, we were able to develop a 4K HEVC-compatible ingest and clipping tool that not only met the client’s needs but that will also prove valuable in a range of other production environments.”
在当前部署中, 4K footage of every class from four studios is fed through a switcher and input via 12G-SDI to 桥的数字’s 4K HEVC encoding solution. 依靠Aja kona 5进行抓捕, 溶液将镜头作为HEVC吸收, 与此同时, creates a frame-accurate proxy that is made available in the Net-X-Code HTML5-supported interface. 一旦登录到界面, the operator can easily view and trim the file in real-time for the correct endpoint and outpoint, 无需重新渲染. An NVIDIA Tesla T4 graphics card powers the GPU processing required for HEVC.
“KONA 5 came highly recommended by the 激烈的 team and checked all of the boxes, 从可负担性到12G-SDI连接, which is a must for handling the bandwidth requirements of 4K delivery. 事实证明，它是一个真正的中坚力量, 以可接受的价格提供可靠的性能, 你不能再要求更多了,默里解释道。.
随着4K迅速成为行业标准, and consumer demand for live and VOD content reaching a fever pitch, 桥的数字 expects the demand for similar encoding solutions to grow in the future. 他的结论是, “4K拍摄将很快成为常态, and professionals will need a set of tools that make it easy to create and deliver complex codecs like HEVC. The goal with our latest solution is to help companies maintain video integrity by keeping the file as close to the source quality as possible and avoiding conversion between capture and delivery. 这样做的时候, 他们也可以利用时间, 节省空间和成本, which are key considerations as consumer appetite for content continues to surge.”
