Running the QuickTime TV Installer

Before you install QuickTime TV, make sure you have the
basic system requirements as listed above. Then follow
these steps to install the QuickTime TV software:

(1) Locate the "QuickTime TV 1.5b6" installer application.
Double-click the icon to run it.
(2) Read the disclaimer that appears, then click Accept.
(3) In the Easy Install dialog box, click Install. All the
necessary software will be installed on your computer's hard
disk.
(4) When installation is complete, click Restart.

When you restart, you will find a new folder titled
"QuickTime TV" at the top level of your hard disk. This
folder contains the broadcast viewing and web browser helper
applications. Note that the QuickTime TV Installer will
install new QuickTime video decoders, H.261 and H.263, which
allow for watching at low bit rates. The H.261 and H.263
decoders are PowerPC native and will only install on PowerPC
machines.

Important Information About Version 1.5b6 of QuickTime TV

QuickTime TV, QuickTime TV SD Listener, and Conferencing
Helper Application are posted as free beta software and does
not come with Apple technical support. Do not call Apple
technical support or the Apple Assistance Center with
questions, comments, or problem reports about QuickTime TV.

All known crashing bugs have been addressed. However, this
software is not warranted to be complete or free from
errors. This software has the following limitations:

* If you use classic networking, QuickTime Conferencing will
not load and you will not be able to use QuickTime TV.
Switch to Open Transport Networking by running the Network
Software Selector (in the Apple Extras Folder), select "Use
Open Transport Networking" and restart. Note: if you see the
"Network" control panel in your system folder, then you are
using classic networking; if not, you will see the
"AppleTalk" and "TCP/IP" control panels instead.

* If you are using Open Transport 1.1.2 and notice that
memory isn't being released after you quit the applications,
uncheck the "Load only when needed" checkbox in the options
dialog in the TCP/IP control panel.

* QuickTime TV can interoperate with QuickTime TV
Broadcaster. QTTV can watch broadcasts originated by
QuickTime TV Broadcaster, but the broadcaster must be
sending media in an acceptable format for the watcher. For
example, a 68040-based MacOS computer can not handle receipt
of H.261 video. The QuickTime TV Broadcaster party should
choose 'PhotoJPEG' or 'Video' to send media to the
68040-based MacOS computer.

* Pausing during recording may cause problems. Some
configurations are not able to resume recording if video is
paused during recording. The symptom of this problem is a
blank movie (with no recorded video) after a pause. For this
reason, pausing is NOT recommended during recording with
QuickTime TV.

To View an RTP/SDP Broadcast

* Launch the "QuickTime TV SD Listener" application. Let it
run in the background. It will gather information on ongoing
and upcoming RTP broadcasts.

* Launch the "QuickTime TV" application.

* Select the menu item "New RTP Channel..." from the "File"
menu.

* Select the session you wish to watch and click on
"Select." Note that you may have to wait a few minutes
before the session you wish to watch appears in the list
(depending on how long QuickTime TV SD Listener has been
running). Alternatively, you click on "Type-in" if you know
the IP address and port number of the session you wish to
watch.

* The broadcast will be viewed via RTP. It may take a few
seconds before you receive media.

To View a QTTV Broadcast

* Make sure that your computer is properly configured to use
the Internet.

* Launch the "QuickTime TV" application.

* Select the menu item "New TCP/IP Channel..." from the
"File" menu.

* Type in the domain name or IP address of the QTTV live
broadcast you wish to watch.

* The broadcast will be viewed via the Internet.

While viewing a broadcast, you can store a "QTC Calling
Card" for a QuickTime Conferencing Internet broadcast by
selecting the "Save Channel..." menu item in the "File"
menu. The next time you wish to tune into the broadcast you
can select the "Open Channel..." option and select the QTC
Calling Card for that broadcast.

Watching a broadcast can be initiated from a web page. A URL
to a stored-address file (with a .qtc extension) can cause
QuickTime TV to launch, open a "Web Calling Card" file, and
attempt to make a connection to the address described in the
file. The server and browser must both be properly
configured for QTC; this process is described below.

Configuring a Web Browser for QuickTime Conferencing Calling
Cards*

*Important NOTE: The information below describes how to use
the Conferencing Helper Application with QTC Calling Cards.

Netscape Navigator 2.0 is pre-configured for QTC calling
cards. Navigator 3.0 is not.

To configure other web browsers so that they may view live
broadcasts and connect to other users for videoconferences
on the Internet, follow the steps listed below:

(1) Install the "Conferencing Helper Application" as the
Helper Application for the Mime Type "video/x-qtc", with the
file extension ".qtc".

Specifically for Netscape Navigator (version 3.0), follow
the directions below:

* From the "Options" menu, choose "General Preferences". The
"Preferences" panel opens, showing a variety of preferences.

* Choose the "Helpers" tab at the top of the window. The
window changes to show the "Helper Applications" settings.

* Click on the 'New' button

* Specify the MIME type as "video"
 
* Specify the MIME sub-type as "x-qtc" and click the "OK"
button.

* Type ".qtc" in the extension field.

* Set the "Action" to Launch Application.

* Click on "Browse", and then a file directory pop-up is
displayed. Browse through your directories, and select the
"Conferencing Helper Application" in the local "QuickTime
Conferencing" folder on your hard disk. When you are done
with this step, the "Conferencing Helper Application" will
be displayed as the helper application for the Mime type
"video/x-qtc" with action "Launch" and extension ".qtc".

* Click on the "Apply" button.

* Close the preferences panel of Navigator, and close the
application. When you restart Netscape Navigator, you will
now be able to launch the appropriate QuickTime Conferencing
application to view live broadcasts.

QuickTime Conferencing and Firewalls

At those sites with Internet firewalls, it may be necessary
to configure the firewall so that QuickTime TV can use
certain features.

* To allow incoming QuickTime Conferencing broadcasts to be
received at an Internet site, it is necessary to allow
incoming TCP traffic on port 458.

* To allow QuickTime Conferencing media streams to flow in
through the firewall, it is necessary to allow incoming UDP
traffic with static port 458 and with dynamic port values
greater than or equal to 7000.
