Haivision, Wowza, Mirror Image, Cisco Offer Multi-Screen Advice
Streaming video to smartphones and set-top boxes is an essential nowadays, but doing so successfully has many companies in the dark. To help them out and offer best practices, representatives from Haivision, Wowza, 镜像网络, Cicso系统 参加了 网络研讨会 yesterday hosted on StreamingMedia.com.
The hour-long 网络研讨会 kicked off with Peter Forman, vice president of business development for Haivision, who focused on the challenge of streaming live video. While live video doesn't have the same codec concerns as video-on-demand, network challenges are bigger.
For encoding or transcoding live streams, Forman recommended making sure that horizontal and vertical resolutions are divisible by 16, recommended against creating custom renditions for every screen. He suggested that companies use live cloud transcoding where they need it and listed reasons to do so: lower uplink bandwidth requirements, 更低的资本成本, 易于操作.
From the server perspective, the biggest challenge is streaming for different screen sizes, 克里斯·诺尔顿说, vice president of product management at Wowza. Knowlton showed a graphic illustrating a common workflow for streaming to multiple formats, one that uses multiple servers. He then showed a simplified workflow where the camera connected directly to a Wowza server, which handles all needed formats. DRM is available as an add-on, he said., users can add a management and billing layer on top of the system.
大脑周, the video stream sales engineer for 镜像网络, offered reasons why companies should use a CDN (content delivery network), such as reducing infrastructure and operating costs, avoiding internet congestion.
The modern approach to video delivery is to move complexities off the origin server and over to the CDN, 周说. He showed how Mirror Image can perform device detections to ensure the correct video is served, how it prevents link-sharing with a token validation system.
Getting into the business side of multiscreen delivery, 迈克·巴罗斯, global director of ABR sales, 市场营销, channel partners for Cisco Systems, said that even though many companies are doing multiscreen initiatives, 很少有人能从中赚钱.
Reach, engagement, agility at the keys to a successful deployment, said Barros. Reach means the number of viewers or subscribers, engagement means the time spent watching, operational agility refers to the new world of partnerships. Barros highlighted this year's Super Bowl, which was streamed for the first time. He called the online experience better than the television experience, although 有些人不同意.
完成了, Barrow offered best practices such as increasing content stickiness and experimenting now for future growth. A sustainable business model will emerge, he said.
During the question and answer session, 网络研讨会 attendees asked about live streaming over low bandwidth and streaming to a small location, 比如体育场.
