Adobe Connect Webinars

A Webinar is seminar conducted over the Internet using legacy video and Internet protocols.  The participant sees multiple pods within their webinar window.

The primary pods in a webinar room are a live video and audio feed of the presenter, a PowerPoint presentation, and a chat or Q&A pod.  Additional pods can be added that contain static elements like logos & webinar descriptions; and interactive elements like polling questions and web, survey, or download links.  Additionally, the entire look of the webinar can be changed by creating additional rooms for a pre-webinar lobby, a main webinar room, and multiple break-out rooms for group work.  Webinar pods can be added “live” during the webinar.
The overall webinar window is broadcast at a 1024×768 resolution at 20 frames per second at a bandwidth below 1Mbps.  Adobe Connect automatically resizes for each individual viewer to fit their screen and individual pods can be viewed in full screen, however the resolution of an individual pod is a maximum of 860×480.  Webinars are conducted with virtually no latency, or broadcast delay, similar to a webcam conversation.
A webinar recording will contain all the pods exactly as they were broadcast live and requires editing to replace the video with the higher quality camera recording and change the on-demand version to only show the video and the PowerPoint presentation in a picture-by-picture view.
Remote presenters or participants may interact on a webinar using a webcam, headphones, and microphone, but when there is a live webinar audience in-studio, there are important audio feedback considerations that need to be discussed in advance.

Webinar Differences and Advantages

The biggest reasons that our customers select a webinar is that they can create live polls and individual registered participant login-ins, secured by password, and they can track individual user viewing down to the minute.  This is useful when you need to verify that a participant viewed the entire webinar for continuing education credits.

Webcasting or Live Video Streaming on Ustream Enterprise

A webcast is a video broadcast conducted over the Internet using modern video and Internet protocols.  The participant sees a single video window containing a high definition video presentation and audio.

The webcast producer uses a video switcher to switch the view between one or more HD video cameras and computer presentations.  A chat or Q&A window can be added next to the HD video.  The webcast video and chat/Q&A box can be embedded on a website or viewed from a channel page and the video can be viewed as a video within a webpage or as a full screen video at the broadcast resolution, usually 1280×720 at 30 frames per second.
All other static or interactive elements can be added to the channel or webpage but do not form part of the broadcast.  The look of the webpage cannot be changed while “live” and polls must be conducted using external survey links.  Additional modules can be added to a webcast service, including viewer registration with customizable fields, and analytics to see the number of unique and concurrent viewers, their geo-locations, and details on their viewing devices.
If an on-demand version is requested, an on-demand version can be edited and available within minutes of the live webcast.  This on-demand version will have the start and finish trimmed, to cut-out the 15-30 minutes of the pre-webcast holding slide.  If additional editing is required for content, the editing process is much quicker with a webcast.  Webcasts are usually broadcast at 2.5Mbps and re-encoded in the cloud to add several lower resolution and bitrate versions that viewers can manually select or that will automatically be switched-to if their Internet speed fluctuates below the broadcast bitrate.

Webcasts are broadcast using group of picture interframe compression, which is more efficient than the webinar intraframe compression that compresses each frame individually .  This difference in compression introduces a broadcast delay on webcasts but also benefits the viewer by helping to reduce audio and video drop-outs if there are momentary computational or Internet delays.  The broadcast delay is usually between 15-30 seconds and this delay has production considerations when real-time interactivity or remote presenters are being considered.

Webcast Differences and Advantages

The biggest reasons our customers select a webcast is when they want to reach a larger audience with the highest quality video possible and then make an on-demand version of the live webcast available within minutes of the live broadcast.
