IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements,
improvements, and other changes to its products and services at any time and to discontinue any product or service without
notice. Customers should obtain the latest relevant information before placing orders and should verify that such information is
current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order
acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s
standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty.
Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should
provide adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask
work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services
are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such
products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under
the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of

may be subject to additional restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service
voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business
practice. TI is not responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would
reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement
specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications
of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related
requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any
applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its
representatives against any damages arising out of the use of TI products in such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products
are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet
military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-
grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in
connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI
products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use
any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.

About This Manual
This document describes how to install and work with Texas Instruments’
(TI) H.264 1080i@60 Baseline Profile/High Profile Encoder
implementation on the DM6467 platform. It also provides a detailed
Application Programming Interface (API) reference and information on
the sample application that accompanies this component.
TI’s codec implementations are based on the eXpressDSP Digital Media
(XDM) standard. XDM is an extension of the eXpressDSP Algorithm
Interface Standard (XDAIS).
Intended Audience
This document is intended for system engineers who want to integrate
TI’s codecs with other software to build a multimedia system based on
the DM6467 platform.
This document assumes that you are fluent in the C language, have a
good working knowledge of Digital Signal Processing (DSP), digital
signal processors, and DSP applications. Good knowledge of
eXpressDSP Algorithm Interface Standard (XDAIS) and eXpressDSP
Digital Media (XDM) standard will be helpful.
How to Use This Manual
This document includes the following chapters:
Chapter 1 - Introduction, provides a brief introduction to the XDAIS
and XDM standards. It also provides an overview of the codec and
lists its supported features.
Chapter 2 - Installation Overview, describes how to install, build,
and run the codec.
Chapter 3 - Sample Usage, describes the sample usage of the
codec.
Chapter 4 - API Reference, describes the data structures and
interface functions used in the codec.
