Webcasting or Live Video Streaming on IBM Cloud Video Streaming Manager

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 1920×1080 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.
Clients that need to track viewership for continuing education credits or professional development are encouraged to very attendance using check-ins in the chat or Q&A module or by requiring viewers to submit an online quiz using one of the many online survey or form services available online.
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.  Webcasts are usually broadcast at 6Mbps 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.  Archive HD recordings are usually recorded and edited at 25Mbps and delivered as an archive video file at 12Mbps.

Webcasts are broadcast using group of picture interframe compression, which is more efficient than 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 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.
