Live Webcast Captioning
(Windows Media Player)

Accurate, Easy & Affordable
Realtime captioning of webcasts just got easier and better – for both the viewer and the provider.

Up until now, for live webcasting, captions and video were sent via different streams.  Since video streaming requires a lot of bandwidth, while text streaming requires almost no bandwidth, captions are transmitted much faster than video. 

The Realtime Webcast Captioning Solution
The CPC solution is the first and only realtime webcast captioning solution, which inserts caption text directly into the web audio/video stream. Because the video, audio and captions are broadcast together in a single stream, the captions and audio remain in synch, no matter what the speed of the internet connection of the Web Browser computer. This is the key to the whole system. 

This breakthrough allows caption/spoken dialogue synchronization within 2-3 seconds, exactly the same as that of television broadcasts. 

With other realtime webcast captioning systems, captions could appear up to 10 seconds before or after the words are spoken, depending on the speed of the connection. Imagine trying to understand a subtitled movie in which the subtitles appear 10 seconds before or after the actors speak their lines. It would be very frustrating at the least.

How Does it Work?

CPC’s realtime webcasting software works in exactly the same way as broadcast video is captioned today, with two components: a Caption Entry System, and a caption Encoder.   

The Caption Entry Software

The Realtime Caption Entry Software is simple to use, and can accept input from almost any steno writer hardware and any steno writing software, or from speech recognition software.  The Caption Entry Software can be used from anywhere in the world, regardless of the origination point of the video webcast.  As in traditional live television broadcasts, the captioner listens to the broadcast on site or live over a telephone, and enters the text into the Caption Entry software. The text is then immediately sent over the internet to the caption Encoder. 

The Encoder Software

The Encoder Software runs on the same computer that is used to broadcast video and audio onto the Web, called the Video Web Broadcast Server.  As the encoder receives captions from the Caption Entry Software, the captions are inserted into the video, as is the case with traditional live TV broadcast captioning.  It is important to note that the captions are not sent in a separate stream, nor are they sent along with the video, they are inserted directly into the video stream, just like conventional TV captioning. 

CPC’s unique technique to add PowerPoint slides to any live event makes it a full featured live presentation system. Since the PowerPoint slides are computer images, they are extremely clear. You can see all the details. In conventional webcasting, PowerPoint images are converted to video and replace the video of the presenter. You can not see both. With CPC’s technology, you can see the presenter and the slides – both at the same time.

Convert Live Webcast to Video-on-Demand Automatically

While the live event is in progress, CPC saves the video with the captions and the links to the PowerPoint slides on the hard drive of your video server computer. After the live event is over, you can simply take the video and put it on the web for people who want to see the video later on at their convenience. You do not have to do the work twice. 

In the live webcast, all the PowerPoint slides are displayed at the bottom of the screen. When the live webcast is converted to video-on-demand, you get one additional feature. With the video-on-demand you can randomly access the video by clicking on the PowerPoint slides and jump to the corresponding location on the video. 

Automatically Captions a Webcast Version of a Live Captioned TV Broadcast 
– No Labor Required!

By adding a simple caption retrieval device, and an inexpensive video capture device, you can simultaneously broadcast all of your live captioned television broadcasts on the web, as captioned webcasts, with no added manpower  

Instead of using a webcam to broadcast your video, connect your live captioned video stream to a video capture device and broadcast the captured video over the web as it is being broadcast live on television.  Run the video through a caption retrieval device before it goes to the video capture device. Connect a serial cable from a caption retrieval device to your computer.  From the Caption Entry software, select Retrieve Caption option, and press start.  Voila!  The Caption Entry software will automatically pull the captions from your already captioned live video stream, and will insert them directly into your simultaneous live webcast! 

Caption Webcasts From an Existing Script

For those times when you already have a script for your event, there’s no need to hire a stenographer.  With the CPC-800 Caption Entry software, you can open a text file and use relatively unskilled labor to send out your text one line at a time.  In addition, we understand that not everything always goes according to plan, which is why you can easily edit your text before sending it out, and quickly switch between script mode and live mode.
