A PRACTICAL APPROACH TO LIVE STREAMING
Full Description:
In August of 2001, newspaper editors from across the state of Texas were able to ask questions of Gov. Rick Perry while sitting comfortably in their own offices during the 4th Annual Texas Transportation Summit in Irving, TX. Next, they were able to see and hear him personally respond during an interactive webcast of the governor’s statewide editorial board meeting, which was held in conjunction with the Transportation Summit. This interactive forum is believed to be the first time a governor used live streaming technology to hold such a meeting. Let’s take a look at what went into staging such an event.
Pulling it all together
Prior to the Transportation Summit, Dallas, TX-based ViewCast Corp. arranged for access to two of six ISDN circuits at the site for dial-up, multi-stream video uplinks to Seattle-based Activate Corp. An analog telephone line at the site also offered dial-up laptop access to the Internet for receiving questions from remote participants. A pair of ViewCast Niagara portable streaming encoders, each coupled to one of the ISDN circuits via Cisco 804 ISDN routers, was used to encode three simultaneous streams as follows: ISDN-1 (28K audio only and 56K audio and video with video playback in a QCIF-sized display window); ISDN-2 (100K audio and video with a CIF-sized display window).
