-
- Dear Valued Macintosh User,
-
- Thank you for downloading this beta version of the InterVU MPEG Player.
- InterVU welcomes and encourages your feedback (e-mail:
- macprevu@intervu.com). Please read the following text carefully to
- understand the configuration, installation, and operational requirements of
- the Mac player. Additional information is also provided by a help file,
- Help.html, located inside the InterVU folder installed by this installation
- application.
-
- There are some problems with both the player and its supporting environment
- which are noted in the PRESENT LIMITATIONS section below.
-
- IMPORTANT for Power PC owners: PreVU uses relatively new features of the
- Apple OS in order to offer reliable and enjoyable video playback. As a
- result, the recent 7.5.3 release of the Apple OS is required on Power PC
- computers. Please upgrade your OS to 7.5.3 before installing the PreVU
- plug-in. This upgrade can be obtained from the Apple WEB or FTP sites.
-
- We intend to rapidly address the problems listed below in the next release
- of the player. Until then, we hope this version of PreVU offers you an
- interesting and enjoyable way to "browse" MPEG video files stored across the
- Internet. We welcome your suggestions for improvements and new features.
- Send email to macprevu@intervu.com.
-
- SOME INFORMATION ABOUT INTERVU AND THE MPEG PLAYER
- ----------------------------------------------------------------------------------------
- The InterVU Macintosh MPEG Player is one of several products offered by
- InterVU. These products are designed to make digital video accessible,
- standards based, and efficient to the WEB page developer and information
- provider. Efficient bandwidth management for distribution of video data over
- the Internet is the objective.
-
- The features and modes of operation of the InterVU MPEG player are intended
- to reduce the bandwidth requirements of network video playback: first frame
- preview, streaming playback, MPEG support, and local cached playback.
- Furthermore, the InterVU WEB site demonstrates that small but specific
- videos have significant utility and value when integrated into the WEB page
- multimedia environment. It is InterVU's desire to have this capability
- enhance the value of your message, not distract from it.
-
- The InterVU MPEG player is a unique type of Macintosh application. On 68K
- processor systems, it is what is referred as a "code resource". On the
- Power PC platforms, the player is a "shared library". In either case, the
- player is not a stand alone program. Rather , it is an extension to the
- Netscape Navigator (or potentially any other browser supporting the
- "plug-in" programming interface).
-
- INSTALLATION INSTRUCTIONS
- -------------------------------------------
- PreVU works with Netscape Navigator 2.0 or newer (Atlas is preferred).
- Successful operation of PreVU requires that you install the PreVU "puzzle piece"
- program extension in the Plug-ins folder of the browser (i.e., any browser
- supporting the "plug-in").
-
- - After you finish reading this document, click the Continue button, and
- follow the displayed installation instructions.
-
- Note: If you have multiple copies of a particular browser (e.g., Netscape
- Navigator), and would like to be able run PreVU on all of them, you must
- repeat the installation procedure for each of the browsers. After the first installation
- is complete, a dialog will appear, which will give you two options, namely,
- "Quit" and "Continue". If you wish to install PreVU for use with any another
- version of Netscape choose "Continue", otherwise, choose "Quit".
-
- Some application software packages (e.g., Adobe Photoshop) also have
- Plug-ins folders. Be careful not to install PreVU in the Plug-ins folders
- associated with these other packages.
-
- - Verify that the PreVU plug-in puzzle piece is installed in the "plug-in"
- folder of the browser.
-
- INSTRUCTIONS FOR PLAYING A (LOCAL) DEMO VIDEO
- ---------------------------------------------------------------------------
- 1. Start Netscape Navigator by double-clicking on the icon of Netscape
- Navigator. Note, for this test you do not have to be connected to the
- Internet.
-
- 2. From the File menu, select "Open File".
-
- 3. From the dialog window, find your Netscape Navigator Folder and open it.
-
- 4. Open the "Plug-ins" folder within the Netscape Navigator Folder.
-
- 5. Open the InterVU Folder. Select the file "Help.html" and open it. This
- help file offers, among other useful information, a "Demo" or test video.
-
- 6. To play the video that showed up on this screen, click on the play button
- (i.e., the green triangle), or click anywhere on the video region.
-
- PRESENT LIMITATIONS
- ---------------------------------
- Frame Use (Netscape Navigator problem only--Atlas works fine) ...
-
- If PreVU is used on a page with Netscape frames, PreVU will begin looping.
- InterVU has incorporated a new option that tells PreVU it is working within frames:
-
- FRAMES = YES
-
- The WEB page developer should use this option with the EMBED statement
- on the WEB page. As Netscape improves its streaming interface, this problem
- will be resolved. See note below.
-
- The Broken Puzzle Piece Icon (Netscape Navigator problem only--Atlas
- works fine) ...
-
- You will see some screen/window flashing during first frame preview. PreVU
- uses the "Image" reload control of Netscape to accomplish the "first frame
- preview" feature of PreVU. This is because any partially downloaded video
- file results in a broken icon representation by Netscape at the video's
- location on the screen. The "Image" reload option of the browser enables
- the PreVU player to repaint the video image over the top of the broken icon
- image. Future versions of Netscape will permit us to eliminate this problem
- (see note below).
-
- Stopping the video while in a full screen-playing mode (i.e., when the video
- is the only item on the screen), will result in a broken icon. Clicking the
- "Image load" button will not restart or refresh the image on the screen.
- Nevertheless, the reload button will replay the video. Future versions of
- Netscape will allow us to eliminate this problem (see note below).
-
- Broken icons will also occur as a result of stopping the video when using
- Netscape frames (that is, if the WEB page developer used the "FRAMES=YES"
- option in the EMBED command). Use "Image load" to start playing again. Again, this
- problem is very similar to the above two. And as before, future versions of
- Netscape will allow us to eliminate this problem (see note below).
-
- Reloading the same video or different videos many times will cause Netscape
- to run out of memory, thus preventing any further reloading of the video
- (another broken icon problem). Quitting Netscape and the restarting it will
- resolve (or reset) this memory problem.
-
- NOTE: The current version of Atlas (new Netscape browser) does fix the broken
- icon problem. InterVU detects Atlas and is subsequently able to take advantage of
- its architectural improvements. However, viewing several videos
- would cause Atlas to run out of memory, thereby resulting in instabilty of the player.
- ⌥
- Other Limitations ...
-
- Large video files (multiple megabytes) can cause player stability problems.
-
- The Microsoft Explorer is not yet supported.
-
- Multiple files, with .mpg extension, will show up in the Netscape 2.0 folder
- after an unexpected shutdown. You may drag them to the trash.
-
-
- ENHANCING PERFORMANCE
- ----------------------------------------
- You can improve the performance of PreVU (and also reduce multiple video
- memory reload problems) by increasing the size of the disk cache and memory
- size allocated for Netscape Navigator. This is accomplished as follows:
-
- Increasing disk cache:
-
- Set the disk cache to 512K or more. To do this, pull down the Apple menu
- and select Memory from the Control Panels sub-menu. Then use arrows in the
- control associated with the Disk Cache to set the value to 512K (or more).
-
- Increasing memory for Netscape Navigator 2.01:
-
- The default size of memory allocated for Netscape Navigator 2.01 is 3016K.
- PreVU performs better if you set the preferred size of the memory to 6016K.
- You can do this by selecting the Netscape Navigator icon, and the choosing
- "Get info" from the file menu. Edit the content of Preferred Size to
- reflect 6016K.
