Adobe: 2013年将是MPEG DASH的发现之年

文章特色图片

MPEG DASH might be the future of online video, but how far off is that future? At the recent 流媒体 West conference in Los Angeles, Kevin Towes, senior product manager at Adobe他坐下来接受了红毯采访,讨论了该节目的命运.

“人们之所以如此兴奋,是因为它希望能够帮助简化广播公司的工作流程, 如果你想想今天的工作流程,在桌面、iOS和Android上传输Flash,并连接到电视, there are multiple workflows almost for every single device which means more content encoding, 更多的内容存储, 多个drm, 多种帧大小, and it gets extremely complicated and super expensive for broadcasters,Towes说. “因此,MPEG DASH的精神是提出一种方法,一种格式, 一种加密格式, 一种存储机制, 一种传递方法可以跨所有这些设备使用. And so why everybody is excited about it is because it helps reduce costs, 它有助于减少碎片化, it helps increase the interoperability between encoders and content delivery networks and video players."

2013年将是MPEG DASH年吗. 不完全是,但期待DASH发挥更大的作用.

“还有很多工作要做,”Towes指出. “2012年,我喜欢把它看作是‘意识之年’. 明年将是2013年是发现之年. 如何将这些编码器、cdn、播放器和设备连接在一起,以真正展示DASH试图呈现的弹性和愿景? 然后当我们经历这些的时候它是关于操作化的, getting DASH into the hands of the consumers from a more viewable point of view."

特洛伊: 大家好,我是来自流媒体的特洛伊德雷尔.com coming to you from the red carpet at 流媒体 West in Los Angeles. We like to have some informal conversations with the leaders of our industry. 今天加入我的是Adobe的Kevin Towes,大家好,Kevin. 请告诉大家你是做什么的.

凯文: 你好,特洛伊. 谢谢你们邀请我. I'm the Senior Product Manager at Adobe responsible for media delivery. What that means is responsible for the technologies that include internet protocols, video delivery protocols that deliver video to desktop and to mobile devices.

特洛伊: I know you recently took part in a major release from Adobe, the release of Adobe Media Server. 正确的? We've been hearing about it for months and months but it finally just came out recently, right?

凯文: Exactly, the Adobe Media Server version 5, we're very proud of that product. 今年是它作为产品诞生的第十个年头,它通过RTMP和RTMPE等内容保护技术多次改变了世界, 以及自适应比特率技术,比如动态流媒体. Adobe Media Server has evolved since we started ten years ago as a communications server. 该产品的第五个版本是一个相当大的里程碑. 去年我们推出了第4版.5 which introduced the first time we delivered video to a non-flash client. 这是一个相当大的举动. With version 5 we completed that development with the support for content protection on the Apple platform. And so that we can apply full DRM with Adobe Access mapped with Adobe Media Server. 还有我们的Adobe Access保护流媒体技术,这是Adobe的一项创新,它允许你在Flash和iOS设备上拥有非常简单的发布工作流程,这样你就不需要复杂的存储或复杂的保护工作流程. So Adobe Access Protected Streaming is now supported in Apple devices like the iOS platform.

特洛伊: 大新闻,大动作. 现在就像你说的,这不是一个新产品,但它是一个新的名字. 名字里有什么呢?

凯文: 一个名字包含了很多东西,我们对这个新名字最感兴趣的是它代表了媒体服务器现在是一个具有无限可能性和端点的媒体服务器. As we see more and more devices whether it's Android or Apple or even 微软 devices entering the market, we wanted to position the Adobe Media Server as a technology that was a media server, 不仅仅是Flash. 我们继续把Flash做得非常好,但我们希望确保我们的客户能够在他们想要的设备上扩展这种体验, 满足他们必须满足的优质内容或企业级内容的所有要求,无论是电影还是情节电视节目,甚至是您的企业视频. So requirements like closed captioning and content protection are all part of it.

特洛伊: I've been very impressed that rather than getting protectionist about Flash or fighting against Apple, you guys just want to make the tools that people use to do the best job.

凯文: 这是正确的. 我们的业务是让视频看起来很棒,我们正在扩展这项业务,帮助客户通过分析和广告插入将内容货币化, and so we're absolutely thrilled that we can extend that experience across multiple devices beyond Flash.

特洛伊: Adobe Media服务器, 以前是Flash Media Server,你们可能不知道, 是一部分, 你称之为“黄金时间计划”的新系统的一个组成部分, 这样对吗?? You have to explain this to me because I'm still getting my head around what Project Primetime is.

凯文: Project Primetime是关于为我们的广播合作伙伴提供盈利工作流程,这意味着发行工作流程的每个部分都是Primetime试图解决的问题. 无论是出版, that means packaging or preparing your content it could be content encryption. 可能是传递和编码. Project Primetime使所有这些组件能够在客户端结束的保护伞下聚集在一起, 在你观看视频的设备上. 当你在观看视频时,该设备包含的信息可以通知在该设备上显示的广告. And for those broadcasters whose business model it is to use ads to monetize their content, then Project Primetime enables that so it's about tying analytics with advertising, with rich content publishing and content protection all under one package.

特洛伊: But there isn't one piece of software that people can buy called Project Primetime, right?

凯文: 不,它不是像Adobe Media Server这样的单一产品. 这是一套产品,包括我们最近收购的一些产品,比如Autitude或Demdex,我们现在称之为受众管理器,它允许你获取数据,无论是由Omniture创建的,还是由Adobe Pass创建的,还是由第三方数据系统创建的, we can bring that into Adobe and create segments and inform decisions for the ads that get displayed. 因此,从消费者的角度来看,他们所拥有的价值就是他们正在观看与他们相关的广告, 他们感兴趣的东西. 这对广播公司的价值在于,他们可以对广告商说,我们可以用这个资料来吸引观众.

特洛伊: And Primetime even works with third-party ad servers, is that right?

凯文: 这是一个细微差别. Ad delivery servers could be you content delivery network, it could be your CMS or your OVP. But what we try to do is say if you want to use a separate ad delivery system, that's great. 我们不做广告投放. 黄金时间是关于广告决策的, 对广播公司来说,真正的价值在于对市场的细分,这样他们就可以有针对性地投放广告.

特洛伊: Now Primetime is also fairly new but it sounds like you already have some fairly major clients for it.

特洛伊: 这是正确的. 在过去的12个月里,我们一直在努力工作,将Autitude和Demdex引入我们的平台,并与Adobe Media Server和Adobe Access保持一致. Over the last 12 months we've been working closely with companies like the BBC as well as NBC. 与BBC合作,我们在去年夏天的奥运会上提供了明显的帮助,其中包括Project Primetime的出版部分, 这是Adobe Media Server以及与编码器和内容交付网络的合作伙伴关系,能够产生一个同时播放游戏的系统. 我们还引入了一个叫做黄金时段亮点的东西,它允许BBC获取数据来创建片段和点播片段,这些片段可以在多个设备上消费. 在NBC,我们实际上做了很多广告决策和投放部分,而黄金时间的另一部分是分析和广告,用于NBC的比赛.

特洛伊: Now you're here at 流媒体 West speaking at a panel on MPEG DASH. 让我们来谈谈DASH. Maybe you could tell people just what it is and why is it getting so much hype?

凯文: MPEG DASH是一个行业标准的视频平台. It's a about a file format, a protocol if you will of how you can deliver video over an HTTP network. 它描述了准备或包装内容的最佳方法, 加密内容的常用方法, and profiles that suggest ways to do closed captioning and some of the other key requirements for videos. 它之所以让人们如此兴奋,是因为它希望能够帮助简化广播公司的工作流程, 如果你想想今天的工作流程,将Flash传送到桌面,iOS和Android,并连接到电视,几乎每个设备都有多个工作流程,这意味着更多的内容编码, 更多的内容存储, 多个drm, 多种帧大小, and it gets extremely complicated and super expensive for broadcasters. 因此,MPEG DASH的精神是提出一种方法,其中一种格式, 一种加密格式, 一种存储机制, 一种传递方法可以跨所有这些设备使用. And so why everybody is excited about it is because it helps reduce costs, 它有助于减少碎片化, it helps increase the interoperability between encoders and content delivery networks and video players.

特洛伊: 现在每个人都在谈论DASH,好像它显然是未来. 怎样才能使它成为现在?

凯文: 我们已经做了大量的工作,高通在很久以前就通过3GPP引领了这一潮流,今年又成立了DASH促进会(现在被称为DASH IF),我们通过Adobe吸引了像我们这样的公司, 微软, 杜比, 真正接受DASH并帮助推广DASH的概念,以便广播公司意识到它的好处,并将DASH视为未来的一种方式. 还有很多工作要做. 2012年,我喜欢把它看作是意识之年. 明年将是2013年是发现之年. 如何将这些编码器、cdn、播放器和设备连接在一起,以真正展示DASH试图呈现的弹性和愿景? 然后当我们经历这些的时候它是关于操作化的, getting DASH into the hands of the consumers from a more viewable point of view. 最终通过减少和简化工作流程, 它帮助内容所有者把更多的内容放到网上. 消费者是赢家,因为网上有更多的内容. 广播公司之所以获胜,是因为他们的工作流程要便宜得多, 而像内容传送网络和编码器这样的生态系统之所以胜出,是因为它们支持多平台的能力大大降低了.

特洛伊: 你想给消费者使用它的时间加上一年?

凯文: I would love to have that crystal ball. 我认为,明年我们将看到大量关于DASH的发现和实验,我希望在2013年,我们将开始看到一些真实的事件开始在网上体现出来. 2014 is probably going to be a year where we're going to see a lot more and just continue to grow from there.

特洛伊: 太棒了,谢谢你的到来. 我是特洛伊·德雷尔从红毯上走过来.
