System multimedia
Introduction Multimedia (video, sound, 3 d Surround, etc.) The past is the field of application suppliers and graphics card manufacturers. In the 90s, M i C R O S O f T decided to make Wi N D O W S a powerful multimedia platform and founded the technique of subsequent D i r e c t x. As the progress progresses, almost all multimedia types are directly supported by the Wi N D O W S operating system. Windows 2000 has continued this process, providing video media players, audio services, voice A P i (S P e e C HA P i), and D i R e c T x systems, all of which have important registry entries, system administrators should understand them.
The media player media player is the latest product of the video playback system of M i C R O S O F T (that is, well-known A C T I V E M O V I E E E E E E E E, D i R E C T S H O W and Several Other Names). It has a lot of powerful features, including:. Automatic codec (video software decoder). Support AV i, MPEG and MOV file format. Scalable display area, from compact to full screen. Support stereo. Recorder style Display control. Several elements required for free upgrading media players can be configured directly through registry.
The audio service sound is accompanied by videos, and Windows 2000 itself can play WAV and M P E G sound files, which can be configured by registry. The registry even contains settings with old-fashioned, non-D i R E C T X sound drivers, which is important for traditional applications.
A relative new person in the speech multimedia field is voice, which can be synthesized by computer and can be entered from the microphone. Windows 2000 saves important information about its SPEECH API in the registry entry. The voice demonstration provided by M i C R O S O F T is very attractive, which can be programmed to accept voice commands, even providing fairly complex user interface behavior with database interactions.
DirectXD I R E C T X is the name of M i C R O S O f T for its multimedia A P i, which originated from old-fashioned MCI (Media Controli N T E R F A C e, Media Control Interface), and several similar techniques. D i r e c T X technology has the following main four types:. D i R E C T P L a y: A technique for playing games through the network (I N T E R N e t or local area network). D i r e c T P L A y tracks the available game information by registry. . D i R e c t m u s i c: Directly create synthetic music (synthesizer has been referred to as M i D i) instead of simply playing recording. D i r e c t m u s i c contains all information supporting the functions supporting the synthesizer in the value of the registry. D i R E C T 3 D: As its name suggests, D i R e c T 3 D is directly using mathematical information instead of a bitmap to create a virtual three-dimensional object on the screen. D i R e c T 3 D requires a lot of hardware support to work and save this information in the registry entry. . D i r e c t D r a W: D i r e c t D R A W is responsible for accelerating a simple graphical drawing operation, especially bitmap operation. But it is not saved in the registry, mainly because most of this information is stored directly in the graphics card, not in the software.
Check if hardware supports Direct3D
In some cases, it may be necessary to determine if the Windows 2000 computer has hardware that supports D i R E C T 3 D (eg, virtual modeling task). System administrators can check the registry in accordance with the following steps to figure out this: 1) Open the Start menu and select "Run". Click the "Browse" button to start navigation until the root directory of Wi N D O W S2 0 0 0 (usually W I N N T) is found. Go to the S Y S t e m directory and find R E G E D T 3 2. E X E, select it to the dialog and click the "OK" button. The Registry Editor is launched, and all configuration units are displayed in different laminate windows, respectively. 2) Select "Window" menu item H k e y _ L O c a l _ m a c h i n e, its sub-window display. Maximize this window for use. 3) Find the tree control using the left window to find S O F T Wa R E / M I C R O S O F T / D I R E C T 3 D / D R I V E R S / H A L. Click this subkey to select it, display its value in the right window. 4) If the value is seen in the H a L item, then the video card supports D i R E C T 3 D. If you don't see a value, then the video card does not support D i R E C T 3 D. Determine if an application uses DirectDraw
In some cases, it may be necessary to determine if a Windows 2000 program has hardware that supports D i R E C T D R A W (eg, virtual modeling tasks). System administrators check the registry to figure out this. First, run the application in quotation marks, follow these steps: 1) Open the Start menu and select "Run". Click the "Browse" button to start navigation until the root directory of Wi N D O W S2 0 0 0 (usually W I N N T) is found. Go to the S Y S t e m directory and find R E G E D T 3 2. E X E, select it to the dialog and click the "OK" button. The Registry Editor is launched, and all configuration units are displayed in different laminate windows, respectively. 2) Select "Window" menu item H k e y _ L O c a l _ m a c h i n e, its sub-window display. Maximize this window for use. 3) Find the S O F T Ware / Microsoft / DirectDraw / MostRecentApplication child using the tree control of the left window. Click this subkey to select it, display its value in the right window. 4) If you see the name of the application in the value n a m e of this item, then the program supports D i R E C T D R A W. If you don't see it, the program does not support D i R E C T D R A W.
