Introduction
High Definition (HD) content is gaining in popularity, driven by the increasing availability and affordability of HD-capable televisions, new releases of movies on HD media (Blu-ray entertainment experience.
It may be possible for consumers to upgrade their current PCs by adding new HD DVD and/or Blu-ray lack the required processing capabilities for fully featured and smooth HD content playback. HD content presents many challenges, including:
Large quantities of data processing

& HD DVD) and a desire by consumers for a more immersive

optical drives; however, the remaining PC components might
o up to six times the rendering required of standard-definition content o it is also memory bandwidth intensive
Computational complexity of algorithms for decode (i.e. CABAC) and processing (i.e. advanced de-interlacing)
High power consumption levels as PC resources run intensively to decode HD content, which can reduce battery life on notebooks and increase noise levels caused by the fans of the system running to dissipate heat
o This is not ideal in a home theater scenario
HDCP and content protection mechanisms included on most HD media by content providers (movies studios, cable providers…). If these requirements are not supported properly, consumers may encounter issues to playback HD protected content on their PCs.
In the past, the ATI Radeon™ X1000 series of graphics processors from AMD sought to overcome these challenges by harnessing the GPU processing power hardware to assist in the video decoding process. This innovation moved the major part of the video decoding off the CPU, while taking advantage of the GPU graphics power for post processing routines designed to enhance the image quality.
AMD continued its efforts to deliver an exceptional home entertainment experience for consumers with the ATI Radeon™ HD 2000 series. These products leveraged ATI’s Avivo™ HD technology to provide a comprehensive solution t o the challenges of HD playback.

Unified Video Decoder (UVD)
To enable the largest number of consumers to playback HD content on their PCs, from thin notebooks to entry-level PCs, AMD introduced the Unified Video Decoder, or UVD. Initially featured on the ATI Radeon™ HD 2400 series, ATI Radeon™ HD 2600 series, ATI Mobility Radeon ™ HD 2300, ATI Mobility Radeon ™ HD 2400 and the ATI Mobility Radeon ™ HD 2400 XT, UVD is a dedicated video decoding block that facilitates the full, bit accurate, decoding process of VC-1 or H.264/AVC encoded video. The entire range of ATI Radeon™ HD 3000 series desktop GPUs now feature UVD with further processing improvements.
By utilizing dedicated hardware for the decoding of VC-1 and H.264 encoded video, the CPU is alleviated from the decoding process and the graphics pipeline and CPU cycles are freed up. The decreased drain on system power is particularly beneficial in notebooks, where HD playback processing on the GPU places a lesser burden on the battery life. Less overall heat is produced, resulting in a quiet er system as fans are not required to spin as fast and move as much air to dissipate the heat.
Processing of HD video requires large amounts of memory bandwidth. The initial implementation of UVD on the ATI Radeon dependant on the available memory bandwidth on a given board. The net result was, at launch, the lowest bandwidth ATI Radeon playback of all HD content at 720p pixel resolutions. If the desktop resolution was set any higher than 720p, then HD video decoding would fall-back to software in order to save GPU bandwidth.
Subsequent Catalyst™ software updates have improved the situation such that VC-1 and H.264 content encoded in 1080p will play back using UVD at desktop resolutions as high as 1920x1200 (higher than 1080p), however 1080i VC-1 and H.264/AVC as well as HD MPEG-2 content still fall-back to fully software based decoding.

The net result is that even the DDR2 equipped ATI Radeon™ HD 3450 will facilitate hardware decoding of 1080p and 1080i VC-1 and H.264/AVC encoded content at 1920x1200 / 1080p desktop resolutions.

HDCP Support
The advent of new HD optical discs, such as Blu-rayTM and HD DVD, as well as dig ital cable on PCs, mandates certain requirements to playback protected content at HD resolutions. Certain technology licensing specifications mandate that these new technologies comply with content protection mechanisms. In particular, when stored on Blu-ray resolutions if HDCP is supported on both the PC and the monitor.

HDMI & Audio Support on the ATI RadeonTM HD 3000 Series
To be compliant with Windows Vista® Premium logo requirements, a system with enabled HDMI output must include two distinct audio sources – one main system source and one for HDMI output. Like the ATI Radeon™ HD 2000 series, the ATI Radeon support for HDMI by including an HD-audio controller on the ASIC, creating a protected audio path separate from the system’s audio, compliant with Windows Vista Premium requirements and without any additional connection or cable.
Combined with the ATI Radeon™ DVI-to-HDMI adapter, ATI Radeon series and ATI Radeon and audio support via standard DVI for easy connectivity and a superior HD experience. Current DVI-to-HDMI connectors do not carry audio, thus do not enable HDMI. ATI Radeon™ adapters handshake with the board to enable audio via the DVI port; when the adapter is connected to the output of an ATI Radeon series or ATI Radeon output.

Summary
The emergence and popularity of HD has created high expectations from consumers looking for a unique and immersive video experience, and this includes consumers choosing to use a PC as the hub of their entertainment center. But as a relatively new technology, HD brings new challenges related to the large quantity of data needed to be processed in HD, as well as its computational complexity, power consumption and need for content protection.
GPUs can play a critical role in providing consumers with a high quali ty and seamless HD playback experience. Unfortunately, many of the current graphics solutions on the market do not provide the performance for full-quality HD playback, and in some cases, lack the proper support for HDCP, audio and HDMI output preventing end users from fully enjoying the complete HD experience.
With ATI’s Avivo™ HD and its unique video playback technologies such as UVD and advanced image post processing, a comprehensive approach to HDCP requirements and seamless support for audio and HDMI interfaces, the ATI Radeon series address HD playback challenges for The Ultimate Visual Experience™ for HD.

How To Evaluate Video Playback Performance
While video image quality is paramount in choosing the right solution, playback performance is of equal importance. This applies especially to PCs that are set up as media centers where multi-tasking is a necessity.
Here are some guidelines on how to properly measure video playback performance: Step 1: Make sure that there aren’t any unnecessary tasks running in the
background. End all unnecessary tasks using Windows Task Manager.
Step 2: Set the desktop resolution to 1080P (1920x1080) through Windows Display Settings.
Step 3: Launch Window’s performance monitor by pressing Window key + r and typing “perfmon” in box. Alternatively, you can create a
shortcut to this application located in the “C:\Windows\System32\perfmon.exe” folder.
ATI Radeon™ HD 3450 - Video Review Guide 8
Step 4: Once Windows’ Reliability and Performance Monitor application launches, configure it to record CPU activity for at least 120 seconds (2 minutes). You can do so by first activating the Performance Monitor window:
Proceed to the Action Æ Properties menu where you can change the duration and frequency of the CPU activity logger to the amount of time you plan to test each scene/clip in a movie:
AMD believes that 120 seconds of playback is sufficient for obtaining an accurate measurement of CPU utilization for video playback. AMD recommends that you test
ATI Radeon™ HD 3450 - Video Review Guide 9
scenes with high bit-rate to evaluate how the system will perform under heavy workload from decoding video streams.
Step 5: Launch your software player of choice and make sure that hardware acceleration is enabled for each test. You can enable and disable hardware acceleration by going to the Configuration Æ Video menu:

Step 6: Start the movie and navigate to the scene that you want to use for your testing. Right before the scene begins, switch to the Reliability and Performance Monitor window (by pressing alt-tab) and start the CPU utilization logger by pressing the “unfreeze display” button or by pressing ctrl-f. Return to the movie by choosing the Cyberlink window from the task bar or by pressing alt-tab again.

Step 7: After watching the movie for the amount of time you set in the Performance Monitor, alt-tab to the Performance Monitor and press the Freeze Display button. You can obtain the average CPU utilization in th e information box near t he bottom of the window.
