IBC 2010: 3DTV来了
3D television has seen a varying degree of experimentation in the United States, from Turner Broadcasting creating 3D television broadcasts of NASCAR races and key PGA Tour events to 3ality providing rigs for NEP Broadcasting's production of the first televised NFL game in stereoscopic 3D (S3D), which was broadcast on September 2 in the Tri-State area on Verizon FiOS TV.
在池塘的另一边, 3D体育已经进入主流, 天空体育推出了一个完整的3D体育频道.
3D交付面临的问题, 然而, are far greater than the question of the financial and technical issues faced for delivering 3D content, although the encoding and delivery of 3D content holds interest to StreamingMedia.com readers as S3D content is often now encoded on the same encoders that are used for streaming delivery, 开启了流媒体3D内容的可能性.
最基本的是, 3D重新定义了动画的创建方式, how CGI integrates with a previously shot 3D sequence and how cameras are placed for maximum 3D spatial depth-without jarring the audience of out of the action or scene.
Oh, and all this needs to be accomplished without "busting the budget" or blowing out the timeframe required to create the content.
在IBC 2010, a number of companies will present their own product offerings for various small pieces of the value chain.
在最猛烈的地方, 生产拍摄, Barcelona-based S3D Technologies will demonstrate two tools to help camera crews and directors of photography make real-time decisions.
S3D有一个看似显而易见的软件工具, 但它对快速决策至关重要:3D计算器.
"During a 3D shoot t在这里 are some stereoscopic parameters to bear in mind,公司发言人说, ，比如镜头的焦距, 感光装置的尺寸, the zero parallax points of both images and the max positive parallax of the scene."
“除了, the cinematographer also need to bear in mind the distance of the objects desired to come out of the screen (negative parallax), the size of the screen and the distance between the screen and the viewer,发言人说.
有那么多需要担心的因素, 包括感光装置的组成——无论是胶片, CCD or CMOS-the company provides its S3D Calculator to calculate interaxial and convergence settings.
The calculator works hand-in-hand with the electronics of a stereoscopic 3D rig, such as the company's S3D BS Rig and accompanying Beam Splitter. These hardware devices allow a 35mm HD camera and even Super35 cameras to be mounted behind a mirror box that optically splits the signal for capture on two parallel photosensitive devices.
The calculator provides metadata during the shoot that's key to integrating live-action 3D shots into CGI software packages such as Maya or 3DStudioMax.
To better visualize the scene for 3D integration of CGI sequences, PhaseSpace等公司将展示虚拟3D相机.
PhaseSpace, which showcased its technology at the HP Global Workstations event I attended back in February and again at the recent SIGGRAPH 2010 event, 使用主动led和红外灯连接到演员身上, allowing real-time motion capture to a pair of HP Z800 workstations.
12核威斯特米尔Z800马力的单位有足够的开销, 除了捕捉运动数据, Z800s还可以输出基本的3D环境, overlaying it in real-time over the actors' motion capture 信息, for a visualization only seen on very high budget productions such as Avatar, 谁率先提出了虚拟摄像机的概念.
"The cost of production drops to about $10 per second for motion capture, 从每秒钟几千美元开始, 使用两台Z800工作站,惠普首席执行官特雷西•麦克希里在惠普发布会上说, as part of a joint presentation with Raleigh Studios' Best Practices Lab.
最后, 所有的计算器, beam-splitters and virtual cameras are only as beneficial as the delivery medium. 许多公司将展示非实时编码, and a very small handful will be showcasing run-time encoding of stereoscopic 3D. 有关这些公告的更多信息，请参见公开宣布.
In a further attempt to understand the challenges facing production and business models for cost-effective 3D delivery, Interxion将主办一场仅限受邀者参加的会议, iStreamPlanet, 微软, 还有其他几个重要的合作伙伴.
会话, 我来调节一下, will look at the benefits and challenges that 3D delivery faces, 不仅仅是传统的广播, 但也适用于流媒体传输.
就像奥运会这样的大型活动一样, w在这里 a variety of foreign broadcasts and several NBC business units shared the cost of a consolidated IP HD transport stream, t在这里 appears to be opportunities for cost savings in the delivery of a single S3D feed for both traditional and online broadcasting.
The choice of Interxion as the host partner for this event is also a strategic move, as the Amsterdam-based data center provider is expected to place an IPO offering on the NASDAQ by the end of 2010. Interxion operates 26 carrier-neutral data centers in 13 cities and 11 European countries.
IBC's exhibit halls will be open from September 10-14, 2010, at the RAI Amsterdam Congress Centre.
