Using IP/TV in a Web Browser

IP/TV can be incorporated into a web browser as either a plug-in or a helper application.

When used as a browser plug-in, IP/TV Viewer lets you watch an IP/TV program that is embedded directly in your browser web page. IP/TV also supports the Apple QuickTime Player as a browser plug-in. This feature helps you watch IP/TV programs without having to install IP/TV Viewer.

When invoked as a helper application, IP/TV Viewer is launched directly from your browser so that it runs in its own window.

This chapter describes the following topics:

•Using IP/TV as a Browser Plug-In

•Using QuickTime as a Browser Plug-in

•Using IP/TV Viewer as a Helper Application

Table 10-1 describes the selection of plug-ins by programs in different situations.

¹The IP/TV plug-in is used by default to play a program unless only the QuickTime plug-in is available

²The program administrator can enforce the use of IP/TV Viewer for any program. In such cases, IP/TV Program Manager prompts users to download the IP/TV plug-in to play the program.

Using IP/TV as a Browser Plug-In

The following sections describe how to launch, run, and customize an IP/TV program plug-in, and how to access the IP/TV sample plug-in.

Note To run a browser plug-in, IP/TV Program Manager must be running in your network. You need to have IP/TV Viewer installed on your system with plug-ins.

Launching the Plug-In

To launch IP/TV Viewer as a plug-in, open your browser and enter the URL of the plug-in. Ask your system administrator for the exact location and name of the browser plug-in web page. For example, the URL http://mywebserver/yourplugin.htm jumps to the web page named yourplugin.htm, which is located on the web server named mywebserver.

Running the Plug-In

After you launch the plug-in, the browser web page with the embedded IP/TV plug-in appears. Figure 10-1 shows a sample plug-in with all the toolbar settings defined.

Figure 10-1 is an example of an on-demand program plug-in window. A scheduled program plug-in window has different VCR controls.

Figure 10-1 IP/TV as a Plug-In—On-Demand Program

The VCR controls for an on-demand program include Stop/Play, positioning buttons, Position Control slider, Mute button, and volume control. For a scheduled program, the VCR controls include Stop/Play, Mute button, and volume control.

Refer to Appendix A in the Cisco IP/TV Viewer User Guide for a complete listing of plug-in window toolbar buttons and icons.

Creating and Customizing the Plug-In

To create an IP/TV plug-in and customize the "look and feel" of the toolbar of the plug-in, use the EMBED tag or OBJECT ID tag on the HTML source page of the plug-in. Use the EMBED tag for the Netscape Navigator browser and the OBJECT ID tag for the Internet Explorer browser. Note that the IP/TV plug-in supports scripting only when the EMBED tag for Netscape Navigator is used. If you want to add scripting and are using Internet Explorer, then you must use the OBJECT ID tag.

Note You must be familiar with HTML and JavaScript to script an IP/TV plug-in.

Using the EMBED Tag

For Netscape Navigator, use the EMBED tag on the HTML source page of the plug-in to create and customize the look of the embedded IP/TV plug-in window.

To modify the EMBED tag, follow these steps:

Step 1 Open IP/TV Program Manager and click either OnDemand Programs or Scheduled Programs.

Step 2 Scroll to the desired program and click the Review link. The Review Program window appears.

Step 3 Scroll to the bottom of the window and click Load Plug-in. A sample web page with the IP/TV plug-in playing your selected program appears. This sample web page has all the default settings.

Step 4 If you like the way the web page looks, save it with an .htm extension and go to Step 6. If you do not like the way the web page looks, go to Step 5.

Step 5 To change the default settings, you need to access the .htm file of the program in a text editor. To do this, choose View Page > Source (for Netscape Navigator) or choose View > Source (for Internet Explorer) to display the .htm file of the web page.

Step 6 Change the default settings of the EMBED tag in the .htm file using the following parameters:
<EMBED TYPE="application/x-sdp" 
SRC="path/file.sdp" 
NAME=name 
WIDTH=width 
HEIGHT=height 
[AUTOSTART= {TRUE | FALSE}] 
[INVOKEURLS= {TRUE | FALSE}] 
[SHOWTOOLBAR= {TRUE | FALSE}] 
[SHOWPOSITIONTOOLBAR= {TRUE | FALSE}] 
[SHOWVCRTOOLBAR= {TRUE | FALSE}] 
[SHOWAUDIOTOOLBAR= {TRUE | FALSE}] 
[SHOWSURFTOOLBAR= {TRUE | FALSE}] 
[SHOWMISCTOOLBAR= {TRUE | FALSE}] 
[SHOWDETACHTOOLBAR= {TRUE | FALSE}] 
[SHOWSTATUSBAR= {TRUE | FALSE}] 
[SHOWMINVIEW= {TRUE | FALSE}]>
See Table 10-2 for a description of EMBED tag and OBJECT ID tag parameters.

Using the OBJECT ID Tag

For Internet Explorer, use the OBJECT ID tag on the HTML source page of the plug-in to create and customize the look of the embedded IP/TV plug-in.

To modify the OBJECT ID tag, follow these steps:

Step 1 Follow Step 1 through Step 5 (and Step 6 if necessary) in the previous section, "Using the EMBED Tag."

Step 2 Change the default settings of the OBJECT ID tag in the .htm file using the following parameters:
<OBJECT ID="plugin_title" 
WIDTH=width 
HEIGHT=height 
CLASSID= CLSID:364752D0-9065-11D2-8210-0060B0F139BD

This parameter is optional.
¹Used only in the EMBED tag.

²Used only in the OBJECT ID tag.

³Do not mix scheduled and on-demand programs in the SURF_OPTION list.
To prevent video from being clipped, you need to consider the toolbar dimensions when designing the HTML source page for the plug-in. The width and height in the EMBED or OBJECT ID tag refer to the size of the window, including video and toolbars.

Toolbar dimensions are:

•Height of each toolbar: 30 pixels

•Width of Audio toolbar:100 pixels

•Width of Detach toolbar: 40 pixels

•Width of Misc toolbar: 132 pixels

•Width of Surf toolbar: 155 pixels

•Height of status bar: 132 pixels

•Width of VCR toolbar: 132 pixels

For example, suppose the existing video size is 320 x 240 and the HTML page author chooses to show the Position toolbar, VCR toolbar, Audio toolbar, Misc toolbar, Surf toolbar, and status bar. The author needs to set the width of the plug-in window to be the maximum of the video width, the sum of the VCR toolbar and Audio toolbar width, and the sum of the Misc toolbar and Surf toolbar width. The height of the plug-in window needs to be the sum of the video height, Position toolbar height, VCR toolbar height, Surf toolbar height, and status bar height. In this case, the video size would be 320 x 348.

Playback Methods and Properties

The IP/TV plug-in supports several attributes that let you manipulate playback of content. These attributes include playback methods and seeking methods and properties. Playback methods for media content are Play, Pause, and Stop. Seeking methods and properties are MarkerName method, CurrentMarker property, Current Position, and MarkerCount property.

Table 10-3 lists and describes the methods and properties that the IP/TV plug-in supports.
Table 10-3 Playback Methods and Properties
Method or Property

Syntax

Description
Play method
plugin_name.Play
Starts playing a video clip from the starting position or continues playing a paused clip. This method has no parameters.
Pause method
plugin_name.Pause
Suspends playback at the current position in the clip. This method performs the same action as clicking the VCR control Pause button. This method has no parameters and does not return a value.
Stop method
plugin_name.Stop
Stops playback of the current clip. This method has no parameters and does not return a value.
MarkerName method
plugin_name. 
GetMarkerName 
MarkerNum
Returns a string containing the name of the marker, given its marker number. MarkerNum is a long value specifying the number of the marker name to return.
CurrentMarker property
plugin_name. 
SetCurrentMarker¹
plugin_name. 
CurrentMarker²
Sets a long value indicating the current marker number. Before you attempt to set this property, determine whether a file has markers and their number by using MarkerCount. If a file has no markers, setting CurrentMarker to anything except 0 (zero) results in an error. Setting CurrentMarker to a number higher than MarkerCount also results in an error.
plugin_name. 
GetCurrentMarker¹
plugin_name. 
CurrentMarker²
Returns a long value indicating the current marker number. This property always returns the current or last marker, which means the actual file position can be either at the current marker or before the next marker. Markers are numbered beginning at 1, so if a file has markers, setting CurrentMarker to 0 (zero) changes the file position to zero.
CurrentPosition property
plugin_name. 
SetCurrentPosition¹
plugin_name. 
CurrentPosition²
Sets a long value of the current position of the clip in seconds.
plugin_name. 
GetCurrentPosition¹
plugin_name. 
CurrentPosition²
Returns a long value of the current position of the clip in seconds.
MarkerCount property
plugin_name. 
GetMarkerCount¹
plugin_name. 
MarkerCount²
Returns a long value of number of markers in the current clip. This property returns zero if a file has no markers. Marker numbers start at 1.

Using the IP/TV Sample Plug-In

If desired, you can use the sample plug-in that comes with IP/TV, which is useful if you want to launch and run IP/TV Viewer solely from a browser without any customization.

To access the sample plug-in, follow these steps:

Step 1 Open your browser.

Step 2 In your browser enter the following URL:

http://mywebserver/iptvfiles/iptv.htm

where mywebserver is the name of your Program Manager.

The IP/TV plug-in appears with the title IP/TV Web Video. All programs on IP/TV Program Manager are listed in the Change Program list.

Web Presenter IP/TV Plug-In Example

This section provides an example of a Web Presenter program IP/TV plug-in. Figure 10-2 shows a browser web page containing a plug-in with three frames: video frame, table of contents frame, and slide presentation frame. The HTML source page for each frame is located in the following directory on the IP/TV CD-ROM:

D:\Demo\Iptv_demo\program files\Cisco Systems\IPTV Demo\Apache\
public_html\iptvfiles

Figure 10-2 Web Presenter IP/TV Plug-In Example

Note IP/TV Program Manager uses "iptv_presenter" for the frame name in the HTML code that it generates for the plug-in, regardless of the frame name specified in the .asf file URLs. If a different frame name is specified in the .asf file URLs, then the presentation URLs are displayed in a separate browser window.

Using QuickTime as a Browser Plug-in

If you do not have IP/TV Viewer or plug-in installed in your device, you can use the Apple QuickTime plug-in to watch IP/TV programs.

The QuickTime client supports ISMA MPEG-4, MPEG-2 with MPEG-1 layer 2 audio, MPEG-1 with MPEG-1 layer 2 audio, SlideCast with H.261 or MPEG-4 video, and PCM (mu-law) audio streaming from IP/TV Server to the QuickTime 6.0 client. However, the QuickTime client does not support MP3, Web Presenter, ScreenCaster, and some audio codecs. QuickTime also does not support password-protected IP/TV programs.

Launching the QuickTime Plug-In

You can open the QuickTime plug-in by clicking the Load Plug-in button in the Review Program window of IP/TV Program Manager.

If you do not have IP/TV Program Manager installed in your device, you can launch the QuickTime plug-in from your browser. For this, you must obtain the URL for the plug-in page from your system administrator. For example, the URL http://mywebserver/yourplugin.htm jumps to the web page named yourplugin.htm, which is located on the web server named mywebserver. When you enter this URL in your browser window, the plug-in launches and starts playing the program associated with it.

Customizing the QuickTime Plug-In

Step 1 Open IP/TV Program Manager and click either OnDemand Programs or Scheduled Programs.

Step 2 Scroll to the desired program and click the Review link. The Review Program window appears.

Step 3 Scroll to the bottom of the window and click Load Plug-in.

Step 4 A sample web page with the QuickTime plug-in playing your selected program appears. This sample web page has all the default settings.

Step 5 If you like the way the web page looks, save it with an .htm extension and go to Step 6. If you do not like the way the web page looks, go to Step 5.

Step 6 To change the default settings, you need to access the .htm file of the program in a text editor. To do this, choose View Page > Source (for Netscape Navigator) or choose View > Source (for Internet Explorer) to display the .htm file of the web page.

Step 7 Modify the EMBED or OBJECT ID tag.

•If you are using Netscape Navigator, modify the default settings of the EMBED tag in the .htm file using the parameters given in the "Using the EMBED Tag" section.

•If you are using Internet Explorer, change the OBJECT ID tag according to the parameters specified in the "Using the OBJECT ID Tag" section.

Using the EMBED Tag

To customize the QuickTime plug-in, modify the EMBED tag on the HTML source page of the plug-in using the following parameters:
<EMBED TYPE="application/x-sdp"

Launching QuickTime from the Web-Based Program Guide

You can launch the QuickTime plug-in from the web-based program guide (WBPG). You can access the WBPG from IP/TV Program Manager as well as through a browser using the URL of the Program Manager host. You can view a program by clicking the Play button next to the program or the program name itself. If your device does not have the IP/TV plug-in or the QuickTime plug-in, IP/TV Program Manager prompts you to download the QuickTime plug-in from the Apple website. You can modify the QuickTime plug-in as explained in the "Customizing the QuickTime Plug-In" section.

Using IP/TV Viewer as a Helper Application

IP/TV Version 3.5 supports IP/TV Viewer as a helper application. The following sections describe how to launch, run, and customize the IP/TV helper application.

Note To create a helper application, IP/TV Program Manager must be running in your network and IP/TV Viewer must be installed.
