Streaming
Nowadays, streaming technology continuously provides data to the desktop but does not download the
whole file. In the ideal situation, the media server that houses the content communicates continuously with
the client to determine how much data the user can handle. Based on this data, the server modifies the data
stream as necessary and transmits just the right amount of data to the client.
The first advantage of streaming is random access. Movies can be viewed at any moment throughout the
video stream thanks to streaming technology. The settings allow your user to advance to the chosen starting
point if they only want to see the last five minutes of an hour-long video. Reduced storage requirements on
the client system are another advantage. Media that is streamed plays instantly on the screen; it isn’t kept in
memory or on the hard drive.

How to Embed Audio in Webpages
The <audio> tag can be used to embed audio in HTML. Previously audio could only be played using web
plugins such as Flash. With HTML 5, audio can now be added to webpages. Three audio formats—MP3, WAV,
and OGG—are supported by this tag on Chrome, Firefox, Safari, Opera, and Edge. Only the Safari browser
does not support the OGG audio format.
Syntax:
<audio src=”filename” type=”audiofiletype”>
</audio>
Attributes of <audio> tag are as follows:
Attribute Description
autoplay Specifies to play audio as soon as the
page loads.
controls Displays the audio controls.
loop Restart the audio when it finishes.
muted Audio will be automatically muted
when the page loads.
src Denotes the URL of the audio file.
Example:
<html>
<body>
<audio controls autoplay loop src=”t1.mp3” type=”audio/mpeg”>
</audio> </body>
</html>
This will play the audio automatically when the page loads. The audio will also keep playing in a loop. Adding
muted after autoplay will let the audio start playing automatically but muted.
