HTPC

Present day consumers use their PCs for multimedia intensive tasks such as HD video playback. These HTPC tasks are not very power efficient when done using the x86 processor alone. Gamers have remained the main focus of the GPU developers. However, the GPU architecture (coupled with a dedicated video decoder on the same silicon) is quite useful for video playback and post processing also. Home Theater PCs (HTPCs) are becoming more and more popular due to a number of reasons. The desire of consumers to watch and enjoy their media, be it Blu-rays/DVDs or broadcast content, in an independent manner (i.e. not limited by DRM restrictions such as with Tivo recordings or even just optical media) has enabled the HTPC industry to gain a lot of relevance, as opposed to getting tied down with non-upgradeable consumer electronics equipment. All three major vendors (Intel, AMD, and NVIDIA) pay quite a bit of attention to the HTPC market in their products, but it is universally agreed that AMD represents some of the most economical HTPC building blocks targeted towards budget system builders, so that's our focus for today.

A Home Theater PC (HTPC) or Media Center appliance is a convergence device that combines some or all the capabilities of a personal computer with a software application that supports video, photo, music playback, and sometimes video recording functionality. Although computers with some of these capabilities were available from the late 1980s, the "Home Theater PC" term first appeared in mainstream press in 1996. In recent years, other types of consumer electronics, including gaming systems and dedicated media devices have crossed over to manage video and music content. The term "media center" also refers to specialized application software designed to run on standard personal computers.

Intel used to integrate the GPU into the chipset till the GMA X4500. AMD acquired ATI, a processor with AMD's x86 CPU and ATI's GPU on the same die was hotly expected. The Lynx integrates a number of AMD Stars cores and also an updated Redwood class GPU (called Sumo) into the same die

HTPC options exist for each of the major operating systems: Microsoft Windows, Mac OS X and Linux. The software is sometimes called "Media Center Software".

GNU/Linux

A number of mediacentre solution exist for Linux, MythTV is a fully fledged integrated suite of software which incorporates TV recording, video library, video game library, image/picture gallery, information portal and music collection playback among other capabilities

Windows

For Microsoft Windows, a common approach is to install a version that contains the Windows Media Center (Home Premium, Professional or Ultimate for Windows 7, Home Premium or Ultimate for Windows Vista, or the older Windows XP Media Center Edition). Alternative HTPC software may be built with the addition of a third party software PVR to a Windows PC. SageTV and GB-PVR have integrated placeshifting comparable to the Slingbox, allowing client PCs and the Hauppauge MediaMVP to be connected to the server over the network.

Mac OS X

Beyond the operating system itself, add-on hardware-plus-software combinations (for adding more full-featured HTPC abilities to any Mac) include Elgato's EYETV series PVRs, AMD's “ATI Wonder" external USB 2.0 TV-tuners, and various individual devices from third-party manufacturers

It has now been almost a year since the Llano lineup was launched; by integrating a CPU and GPU into the same die and bringing along AMD's expertise in the GPU arena for HTPCs, these APUs (Accelerated Processing Units) offer a lot to the budget HTPC builders.

The purpose of a HTPC system is to enable one or more of the following activities:

·         Media playback: The media could be either stored locally (on a hard drive, NAS, Blu-ray, or DVD) or be streamed from the Internet (from sites such as Netflix or Hulu). Media files include pictures and music files in addition to videos.

·         Optical disc backup creation: This involves the archiving of Blu-ray and DVD movies onto a physical disk (such as a hard drive or a NAS) after removing the DRM protection. This enables consumers to enjoy the content on their purchased discs without the annoying trailers and advertisements, or the need for a Blu-ray drive (e.g. on tablets or smaller HTPCs).

·         Recording and/or editing video files: This involves using a TV tuner to capture broadcast content and record it onto a physical drive. The recorded content could then be edited to remove commercials or for any other purpose before being stored away. Sometimes, it might be necessary to transcode the video files as well (say, converting from one H.264 profile to another). This is much more computationally intensive compared to splitting/joining media streams with similar characteristics.

Some users might also want to use their HTPC for activities such as:

·         Gaming: This is, by far, the most common extension of a HTPC outside its original application area. Thanks to the powerful integrated GPU, we have seen that the Llano APUs are quite good with almost all games at mainstream quality settings. If a budget gaming+HTPC build is on your radar, you can't go wrong with the Llanos--provided you understand that high quality settings and 1080p gaming are likely too much for the iGPU.

·         Network DVR/IP Camera recording: This is quite uncommon, but some users might like to have IP camera feeds viewable/recordable through their HTPCs.

·         General PC Tasks: These include basic web browsing, downloading and other similar tasks (which almost all HTPCs are bound to be good with)

AMD's Llano lineup includes a range of processors with TDP ratings from 65W to 100W. Note that simple playback tasks are going to be quite power-efficient, thanks to integrated hardware decoding, so the relatively high TDPs shouldn't put one off. There are also plenty of FM1 socket motherboards based on the A55/A75 FCHs (Fusion Controller Hubs). The choice of the Llano APU, motherboard form factor, and other components should be made depending on the desired usage scenario
