OS/2 multimedia applications, such as Volume Control shown in the following figure provide you with examples of multimedia control implementations. File:img1.png The SW.DLL dynamic link library, located in the \MMOS2\DLL subdirectory contains the functions that support creating and manipulating these controls. (The SW.H fil...")

The sample captioning system consists of three parts: the Caption Creation Utility program, Caption DLL, and Caption Sample Application. The Caption Creation Utility program (located in \TOOLKIT\SAMPLES\MM\CAPTION subdirectory) creates a 'caption' file. This is a text file containing timing information relating to i...")

While this technique provides good performance, it has the disadvantage that each decompressor must deal with the pel format of the display in various modes, clipping the output to visible regions, and any scaling that is to be performed. Additionally, on bank-switched video displays, the...")

The ability to create and record movies is provided by the Video IN product (part of the OS/2 BonusPak). The OS/2 digital video device ('''digitalvideo''') provides file-format support through the multimedia input/output (MMIO) architecture. Several movie file formats including AVI, MPEG, FLC/FLI animation are supported. Several decompression types, like Ultimotion, Indeo 2....")

The analog video output can be connected to an analog video digitizer component that produces output on the display, or it can simply be connected to a an external video monitor. The audio output can be connected to amplified speakers, headphones, or other audio media drivers. == Device Specifics == The videodisc medi...")

CD-XA (Compact Disc-Extended Architecture) refers to a storage format that accommodates interleaved storage of audio, video and standard file system data. CD-XA data is stored in a file system format on the discs, and playback control is managed by the CD-XA media device in cooperation with the amplifier-mixer device. CD-XA takes advantag...")

A typical use for CD audio is to provide high quality audio for use in a presentation. Another use of CD audio would be to provide detailed audio help for an application user. Instead of the usual hyperlinked text and graphics, an entire step by step audio tutorial might be stored on a compact disc in several different languages. :h2 id=94.Compact D...")

Typically, a digital signal processor (DSP) is used to generate the sounds of the instrument, which results in an authentic reproduction of the original performance. General MIDI (Musical Instrument Digital Interface) is a standard specification for pl...")
