Multimedia Objects 2.8-1


Let us Revise!

I. Answer the following questions:
1. Write how you will insert images in your Web page.
2. Name the attributes that are used to change the size of the image in a
Web page.
3. Describe how you will convert an image to a hyperlink.
4. Define Image Map.
5. Write the tag and attribute used to display an image as the background

Introduction
The Web pages that you design must invite the users. The Web pages can be
enhanced by adding Multimedia objects. Multimedia objects are the objects
that enable the user to listen to music, watch movie, enjoy animation and
much more. Adding music, movie and animation to your Web pages is very
simple. These multimedia objects can be added to the Web pages using the
<EMBED> tag along with Src attribute.

2.8.1 Music
To add a flavour to your HTML Web pages, you can add background music to
them. The user can browse your Web page enjoying the background music.

Hands-On!

The following example illustrates how to add music in your Web page.
Open the HTML file Music.html in Internet Explorer.
The code in Music.html file is given below:
<HTML>
<HEAD>
<TITLE> Music </TITLE>
</HEAD>
<BODY Bgcolor="Firebrick" Text="Lightyellow">
<FONT Size=7>
<H1 Align="Center"> National Anthem </H1>
<CENTER><IMG Src="Mal_Flag.gif"><BR><BR>



<EMBED Src="National_Anthem.wav"></CENTER>
<BR>
<MARQUEE BGColor="Black" Loop=1>

Code Sample 2.8.1



Figure 2.8.1: A Web page with Music
When you open the Web page shown in Figure 2.8.1 in a browser, you can
see the text of our National Anthem scrolling across the screen and hear to
the National Anthem. The tag that is used to execute sound files is <EMBED>
tag. Src is the attribute used along with this tag. The name of the sound file is
assigned to the Src attribute. You heard a wonderful music while opening the
above Web page because of the following tag:
<EMBED Src=”National_Anthem.wav”>

The attributes that can be used along with <EMBED> tag are explained in
Table 2.8.1.



Attribute Use Example
Src Specifies the name <EMBED
of the sound file Src=”flourish.mid”>

AutoStart Specifies whether <EMBED
the sound should be Src=”flourish.mid”
played automatically Autostart=True>
or not.

Loop Specifies whether <EMBED
the music should be Src=”flourish.mid”
played indefinitely Loop=True>
or only once. If the
value assigned is
true, it will be played
indefinitely.
Otherwise, it will be
played only once.
Width Specifies the width <EMBED
of the sound control. Src=”flourish.mid”
Width=”45”>

Height Specifies the height <EMBED
of the sound control. Src=”flourish.mid”
Height=”30”>

Table 2.8.1: Attributes of <EMBED> Tag

For example, the following code plays the MIDI file (Sound file) indefinitely.
The height and width of the sound control would be 20 and 30 respectively.
<EMBED Src=”flourish.mid” Loop=True Height=”20”
Width=”30”>

Note

<BGSOUND> tag can also be used to play sound files.



Lab Exercise
Lab Exercise 1: Open D8_1.html in Internet Explorer. The following code will be present in
D8_1.html.
<HEAD>
<TITLE> Music </TITLE>

<IMG SRC="CAKE.BMP"> <BR><BR>
<EMBED Src="HAPPY_BIRTHDAY.MID" LOOP=FALSE
HEIGHT=20 WIDTH=30>
</CENTER>
</FONT>
</BODY>
</HTML>
1. Identify the tag which is used to add the sound in source code D8_1.html.
2. Locate the attribute which is used to assign the sound file.
3. Name the value of the loop attribute which is used to play the music only once.
4. Identify the value of the autostart attribute which is used to play the music
automatically.

Lab Exercise 2: Open D8_1.html in Internet Explorer.
1. View the code in Notepad.
2. Set the Loop attribute value to True and observe the difference.
3. Set the Autostart attribute value to False and observe the difference.

2.8.2 Movies
Adding movies to your Web page is as simple as adding music to your Web
page.

Hands-On!

The following example illustrates how to add movies in your Web page.
