TV DVB-H Receiver HAI Overview</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<section><title>Purpose</title> <p>The Mobile TV DVB-H Receiver HAI (Hardware

Adaptation Interface) is a component that abstracts DVB-H receiver hardware. </p> </section>

<section><title>Required background</title> <p>Mobile TV DVB-H Receiver HAI

provides an programming interface between the receiver hardware and applications

that use the data provided by that hardware. </p> <p>DVB-H (Digital Video

Broadcast-Handset) is the only mobile TV standard supported by the Symbian

platform at the moment. This standard has been field tested in various locations

between 2003 and 2007 and is already being rolled out as the content delivery

platform for mobile TV in various regions. Full details are available from

the <xref href="http://www.dvb-h.org" scope="external">DVB-H project web site</xref>. </p> </section>

<section><title>Architectural relationship</title> <p>Mobile TV Receiver HAI

interacts with hardware through the Hardware Adaptation Layer (HAL) and abstracts

hardware to mobile TV middleware. The diagramatic representation is shown

below: </p> <fig id="GUID-3B3597B1-1BA0-5865-9275-2F39FBC1CBD6">

<section><title>API summary</title> <p>The Mobile TV DVB-H Receiver HAI component

includes the following APIs: </p> <ul>

<li id="GUID-2C6E3315-1D31-539F-B544-C56860F8EB5B"><p> <b>DVB-H Receiver API </b>  </p> <p>Used

to access and control DVB-H receiver hardware. It provides scanning, tunning

and data reception functionality. </p> <p>For more information about DVB-H

Receiver API, see <xref href="GUID-F0C47F37-354B-51BD-B607-D4575C249DC8.dita">DVB-H

Receiver API overview</xref>. </p> </li>

<li id="GUID-196DA2F2-2F9B-5329-BA58-D0913A577910"><p> <b>DVB-H Receiver Information

API</b>  </p> <p>This API is use to retrieve information about DVB-H receiver

and DVB-H broadcasts. This API does not have any control of DVB-H receiver

hardware but only provide information. </p> <p>For more information about

DVB-H Receiver Information, see <xref href="GUID-721A5765-7A9A-58F9-AFAF-ABC559207D23.dita">DVB-H
