这个市场一直被 Accordent 和声波铸造, 和 both made announcements at this week's show.

We'll cover Accordent's strategic approach to the market in the next few weeks, but it's worth mentioning that the company's announcement at the show of an Express version of its Accordent Media Management System (AMMS).

在硬件捕获方面, 声波铸造 announced a new portable Mediasite ML Recorder, which is significantly smaller than the previous version, has the ability to capture DVI or HDMI non-copy-protected content 和 can also automate closed captioning via the version 5.4软件包.

"We have also added Silverlight multicast support,罗布·利普斯说, executive vice president of 声波铸造, ，并正在大力探索H.264 encoding-since Silverlight 和 IIS support it-to complement our current Windows Media audio 和 video encoding."

A rack-mount unit also released at the show has an HD input card option, although the company says its encoding profiles still only support SD video streams. Since many educational institutions are putting HD cameras in new lecture capture room, the HD input card means that a sharper video signal will reach the codec, 从而产生更高质量的SD流.

Ncast, a company whose focus has been on live streaming of graphics, including full-motion capture of DVI/HDMI signals, announced a lectern-mounted capture unit capable of selecting between any two of the input connectors: composite video, VGA, DVI, HDMI, 组件视频.

使用H.264 codec, Ncast can deliver both signals are part of a single raw H.264年流. One of the signals will be sized to its full size, while the other will be in a positionable picture-in-picture (PIP) configuration.

"Our customers don't need to worry about synchronizing slides, 网页, or computer capture with a video stream of the lecturer,汉克·马格努斯基说, Ncast创始人. "All the content is already synchronized, 和 can be delivered as a single 720p video stream."

Ncast使用 Wowza媒体服务器, which I'll be reviewing in the next few weeks, to convert the raw H.264年流 wrappers to allow playback in either a Flash or QuickTime player.

Following on the heels of Wowza's inclusion in T和berg's streaming strategy (now a part of 思科), this week's Wowza announced it will license its Wowza媒体服务器 2 to 原尺寸的通信，现在是…的一部分罗技.

"We've seen significant interest in the telepresence space," said Dave Stubenvoll, CEO of Wowza. “两年前, there was little interest in streaming tie-ins to videoconferencing, but the increase in HD videoconferencing 和远程监控 means that many telepresence manufacturers are looking to us to provide protocol conversion so that desktop users can view a stream of an ongoing videoconference."

It's little wonder that the videoconferencing companies are expressing interest: Frost & Sullivan claims the telepresence market is expected to reach $4.到2014年达到70亿美元.
