同步和. Latency - Which Matters 更多的 in Enterprise and Sports Streaming?

在超低延迟和同步之间取得现实平衡的一些最有效的方法是什么? Tim Siglin, Founding Executive Director, Help Me Stream 研究 Foundation, Contributing Editor, 流媒体, discusses this topic with Chris Packard, Manager, Live Programming & 流, LinkedIn,以及首席执行官奥利弗·列茨 nanocosmos,从本次会议开始 流媒体 Connect 2024.

“How important is 同步hronization versus latency?西格林问道. 他告诉帕卡德, “我知道你提到了在全体会议上让观众中的某个人入职, I know that's sort of the holy grail of w在这里 you're going. 两者之间是否存在平衡?, 虽然, 我们说,只要我们有同步,我们不一定需要超低延迟? Or do we have to have as low latency as possible, everybody 同步hronized receiving the content at the same time?”

帕卡德说,LinkedIn在这些要求上处于一个不同寻常的位置,因为它可能是世界上唯一一家像LinkedIn这样规模的公司,每两周召开一次全体会议,因为它的首席执行官重视沟通. “So if somebody goes in the mic, 在奥马哈说, 内布拉斯加州或伦敦, he can just choose the feed coming right in.他说,LinkedIn在程序中使用超低延迟进行信号采集, but the end user experiences a latency of around 30 seconds, 但他想知道, “如果有这样一个世界,无论是在我们办公室还是在家里的电脑上,演讲者都可以随时举手,进入更多的虚拟舞台, maybe outside the production control room, 但是程序内馈送? 这才是真正令人兴奋的,因为它融合了我们的两个世界,而不仅仅是控制室环境的输出流. So I think that's w在这里 we're getting to. I think we've been 虽然t leaders in this space for some time."

Packard also mentions the potential of incorporating elements from Meta into their meetings, such as the photorealistic avatars that 脸谱网 正在开发. 他说:“脸谱网上超逼真的头像让我大吃一惊. “如果我们能有某种CEO的虚拟形象,可以访问,其他人也都有自己的虚拟形象, maybe that's w在这里 we're heading.“然而, 他说, 最重要的是,面对面互动的平等机会仍然至关重要. “I think that the in-person interactivity is still going to be paramount, 但我们也必须认识到人们在不同的地方,没有某种地域偏见,并确保每个人都有平等的地位来贡献和被倾听.”

Lietz differentiates between broadcast experiences, which require 同步hronization but not interactivity, interactive experiences, which require real-time engagement. “Coming back to the question about 同步hronization, 对于所有情况, 我们认为将每个人的延迟保持在相同的水平是非常重要的,他说. “That means if you have a low latency, like a sub-second stream for everybody, 你不需要太担心同步,因为每个人都在低延迟空间. 这更像是你需要尽可能降低质量,保持直播运行.” With more traditional live broadcast-type experiences, 比如体育直播, 他说, “Everybody wants to enjoy a game or something in an event, maybe in a lean-back experience sitting on a couch on a 4K monitor. And no matter if they are on a TV screen, 电脑屏幕, 或者在手机上, they want to have the same experience, but t在这里's no interaction.“然而, with more interactivity in live events, 他说, “When it comes to betting or interacting with the presenters, 比如买东西, 然后你需要来到实时空间,参与互动体验.”
