Hardware Adaptation Interfaces Overview</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>This document introduces you to the Multimedia Hardware Adaptation Interfaces

collection. </p>

<section><title>Purpose</title> <p>The Multimedia Hardware Adaptation Interfaces

(HAI) collection defines hardware-independent interfaces for controlling the

hardware component, such as:<ul>

<li><p>Video hardware</p></li>

</ul> </p> </section>

<section><title>Architectural Relationship</title> <p>The APIs are introduced with their components.

The Multimedia components DevVideo and DevSound provide APIs for handling

the media data once the raw data stream has been extracted by the Multimedia

HAI components. </p> </section>

<section><title>Description</title> <p>The Multimedia HAI provides support

for controlling the hardware component, and handling the data streams. </p> </section>

<section><title>Components</title> <p>The Multimedia HAI collection includes

the following: </p> <ul>

<li id="GUID-E0BCB995-BC4D-5594-A3A5-32BA557459E7"><p>Video HAI </p> </li>

</ul> </section>

<section><title>Video HAI</title><p>The <xref href="GUID-D9D2A600-89C6-5D82-8BC0-2C60D8F6517A.dita">Video

HAI</xref> defines an interface for plug-ins that provide video functionality. </p></section>

<section><title>Using Multimedia HAI</title> <p>Hardware integrators can write

device drivers or servers to manage the component like:</p><ul>

<li><p>Video</p></li>

</ul><p>These components expose APIs that are independent of

the underlying implementation and hardware specifics. </p> </section>
