Picture Quality: HQV Testing

HTPC enthusiasts are often concerned about the quality of pictures output by the system. While this is a very subjective metric, we have decided to take as much of an objective approach as possible. Starting with the Core 100 review, we have been using the HQV 2.0 benchmark for this purpose. The HQV 2.0 test suite consists of 39 different streams divided into four different classes. The playback device is assigned scores for each, depending on how well it plays the stream. Each test was repeated multiple times to ensure that the correct score was assigned. The scoring details are available in the testing guide [PDF]. In the table below, we indicate the maximum score possible for each test and how many points the ASRock ION 3D was able to get.

As stated before, video quality benchmarks are very subjective; however, it appears that the GT218 GPU in this system is performing very close to the GT 425M found in the Vision 3D system. This is not so surprising as both are NVIDIA PureVideo capable and the drivers used on both are very close in age to each other. There are a few items of note.

The NVIDIA noise reduction algorithm did reduce noise and artifacts, and the difference was apparent when enabled vs. disabled. In my observations, during still scenes the noise reduction worked very well; however, when moving objects were on the screen sometimes the noise filter had a difficult time and the noise did leak out a little. The drivers do not have a specific skin tone correction mode that is user configurable in the NVIDIA Control Panel, but there are color enhancement toggles that did adjust color and tones, but it was not enough to give it a full score with regard to skin tone correction.

    I think I'm going to wait until they start using Sandy Bridge in these. I'd love to see the Core 100HT-BD with the Sandy Bridge. I'm not holding my breath but I've been reading all these reviews and have a friend with the ION version and he loves his. I'm just not sure how much longer I can wait or if I'm going to build my own htpc. I figure I've waited this long I'll see if they can push some out this quarter.

    The Brazos platform will be faster, certainly, however its GPU doesn't have the ability to decode BluRay 3D. You don't seem to have looked at this platform's ability to decode 3D, though (unless I've missed something).

    On the other hand, TomsHardware have reviewed the ASRock E350M1 and noted that Ion's CUDA cores throw out questionable quality when encoding, so it's all swings and roundabouts really.

    I don't want to be "that guy", but it bugs the hell out of me to see HTPC reviews where they don't even see how many cablecard or ATSC streams this thing can record/display at a time. The modern HTPC is of debatable utility if all you're doing is streaming video; there are any number of embedded devices that will do that cheaper and better.

    Exactly how many tuners do you expect to get in that case? My recording is done on an ATX motherboard with 13 total tuners. The reviewed system is a playback system, not a recording system.
  • vol7ron - Friday, January 14, 2011 - link

    At least one for that case.

    Why in the world would you have 13 tuners? What kind of bootlegging business are you running?

    Let me guess, you also have Starz, HBO, Showtime, Cinemax, and sports packages too.
  • erwos - Friday, January 14, 2011 - link

    You can connect tuners via USB (ATI) or over the network (HDHR). Shoving them straight into your computer is actually slightly odd to me.
  • stlbearboy - Friday, January 14, 2011 - link

    3 Directv
    4 OTA
    4 Cable
    3 Clear QAM

    This allows viewing to all every TV in the house via extenders. The most active at one time has been 9. I looked at the HDHR and have 3 HD-PVRs for Directv. Only Sports package is Sunday Ticket but with kids and diverse tastes I like the flexibility. You could use a NAS for storage and HDHR for tuners, although I could not imagine trying to comskip on an ION! But my point still remains, you buy that system for playback not recording. As to the question of how many streams you can record, that is a function of your HDD as ATSC does not take any encoding.

    24W is high power. Regular (non-atom) desktop computers can have similar idle power.
    Atom makes it unsuitable for anything except media use.
    But now there are dedicated devices that are generally more convenient, and lower power. (Popcorn hour, Dune, etc.).
    A full OS is not suitable for pure media use.

    I'm still not sure how ANY device can be recommended for a home theater that doesn't support the full range of bitstreaming options. Dolby TrueHD and DTS-HD MA have been in application for nearly five years. It is simply inexcusable to offer anything less than PERFECT support for these. Intel, NVIDIA, and AMD should be ashamed. Please don't take this question in a hostile way, but what kind of "home theater" are you trying to build?

    Next time a device claims to be a "home theater" device and doesn't support bitstreaming, send it back to the manufacturer. It's high time these folks learned that ANY modern HT device must support the following:

    1. Full lossless and legacy bitstreaming compliance
    2. 23.976 compliance
    3. Simultaneous multi-video and multi-audio streams

    Sheesh, it's bloody 2011.

    So, in other words, this thing is pretty much the same as the old ION 330, except with a bluray drive and some front USB ports? I mean, the difference in both the CPU and GPU is very minor, Atom hasn't seen any major developments since it first launched a few years ago.
