Starting RealPlayer Audio Presentation
When you open "Audio presentation page" you will see 3 parts of page, but you will not hear a sound. You will need to start audio presentation with pressing "Play" button on Audio controls.
When you click on "Play" button your RealPlayer will send request to CARDIOnet Program.
On StatusBar you will see message "Connecting..."
After few seconds, RealPlayer will establish connection with CARDIOnet Program and now it will start receiving data.
On StatusBar you will see message i.e. "Buffering... (6,5 kbps, 4 seconds)"
6,5 kbps means, that you will hear sound in medium quality at 6,5 kilo bits per second, if you have chosen medium quality sound transmission.
If you see 16,0 kbps on message, the sound will be in high quality, if you have chosen high quality sound transmission.
When you choose high quality sound, slides in RealPlayer slideshow presentation will appear slower then in medium quality sound. Sometimes you can lose some slides, if speaking time is very short among two slides.
4 seconds means that you need to wait 4 seconds to hear sound. Time which you need to wait depends on your modem speed, Internet connection and quality of sound which you choose.
RealPlayer always needs to receive in buffer the first 10 seconds of Speaker's presentation.
After this you will receive sound data and hear a sound in real time. It is called "streaming". Streaming is the most popular format on Internet. All famous TV and radio stations on Internet work with RealPlayer streaming procedure
