Hi,
Do you mean that you want your application to send and recieve the audio/video data online. If it is so, I think you can write applets and use them in the application. Or you can also use Macromedia Flash to do the same in a better way. For further info about Flash player please visit
http://www.macromedia.com/software/flash/about.
And as a reference please once visit www.mlb.com, whichhas some video library running on iAS.
Hope this might have given you some poiters that help you. Should you have any further queries please get back to our software forum.
Thanks and All the best,
Rakesh.
