CyberLink Has Released The New PowerDVD 13 Media Player

April 2nd, 2013 · 5 Comments · General 3D News

cyberlink-powerdvd-13


Today CyberLink has introduced their new version 13 of the PowerDVD media player, bringing some new and interesting features and improvements, some of which related to 3D, though not that much is actually targeted especially at stereoscopic 3D support. If you are going to be using the player for Blu-ray 3D movie and would use the player mostly for 3D video playback you’d need the Ultra version as the other two versions of the player – Pro and Deluxe do not come with stereo 3D video support at all.

Among the more interesting features in the new PowerDVD 13 are things like official support for the new AVCHD 2.0 standard (including 3D video support), playback of lossless APE audio (OGG and FLAC are already supported), 4K video support (for bitrates up to 60 Mbps) and a new subtitle rendering engine allowing you to better customzie how the subtitles appear. CyberLink also promises faster startup time for Blu-ray movies, better speed and responsiveness of the playback for various types of media. With the new PowerDVD 13 there is more attention for not only HD and 3D video playback, but for HD audio as well, so if you have a more serious sound system you can enjoy not only high-quality audio from movies, but also play looseless stereo audio and multichannel HD audio as well. It is interesting to note that the new PowerDVD 13 also supports TrueTheater HD for Blu-ray movies and Full HD videos (upscaling resolution) as compared to the previous version 12.

There isn’t much changed on the types of stereoscopic 3D display devices and output modes from the previous version, though they were already quite comprehensive with support for only 3D-capable DLP Link projectors using DLP Link glasses being the only thing that is still missing, though frame sequential mode is supported on a devices using 3D Vision with compatible hardware. PowerDVD 13 Ultra is available with a price of US $99.95 or €99.99 Euro and if you have an older 11/12 Ultra version you can upgrade for half the price of the license.

Using a 3D DLP Projector in Stereoscopic 3D Mode with a PC

The 3D DLP projectors are one of the most affordable solutions to get a large screen with 3D support, whether it is for watching 3D movies at home or for playing games in stereo 3D with a better sense of immersion. There are a lots of models available on the market using various interfaces and having different resolutions and capabilities and all of these may cause a confusion and as a result you may end up with a 3D-capable projectors that does not work the way you wanted it. There are a few very important things that you should be aware of when considering buying a new 3D DLP projector or already have one, but you still haven’t used its 3D capabilities and you want to try them out. One of the most important advantages, besides the large projected screen of a 3D DLP projector is the fact that the technology does not suffer from issues with crosstalk, unlike 3D-capable monitors or 3D HDTVs. So let us see what is the most important information that you need to know.

When talking about a consumer level affordable 3D DLP projectors there are two main types of modes being used for providing support for stereo 3D, these are frame sequential input (can be over a VGA or HDMI interface) or HDMI 1.4 frame packaging. The interface and mode being used by a 3D DLP projector is very essential on what else will you need and how can you use the projector, so you must carefully choose the right interface based on what toy are going to be using the projector for and even depending on what other hardware you have in your PC. You should be well aware of the fact that there are still no affordable consumer level 3D DLP projectors capable of providing 1080p resolution in 3D mode with high-enough refresh rate for comfortable gaming. So regardless of the interface a 3D DLP projector uses and the native resolution it supports you can forget about being able to play games in stereo 3D mode at 1080p resolution for now, but you can still watch 3D movies at Full HD resolution if the projector is with 1080p native resolution. And this is just one of the examples of the limitations and features you should be well aware of when considering to use a 3D DLP projector, especially if you still haven’t purchased one. But there are a lot more specific things…


3D DLP Projector with frame sequential support:

– You can supply the frame sequential output over VGA or HDMI 1.3 interface.
– The projector is limited to 720p resolution in stereo 3D mode as maximum.
– In order to use the projector in stereo 3D mode it has to be in its native resolution (can be up to 720p).
– Besides being able to use stereo 3D mode at 60Hz per eye, you can also use 120Hz refresh rate in 2D mode.
– You can use any standard pair of DLP Link glasses with it, there is no need for any kind of emitter as the technology uses special kind of white light flashes embedded in the image being displayed.
– With DLP Link glasses you are good to watch 3D videos with the help of any software player capable of outputting 3D in frame sequential mode such as the Stereoscopic Player for example.
– With DLP Link glasses you are not able to directly play games in stereoscopic 3D mode or watch Blu-ray 3D movies without having to meet some additional hardware requirements and use extra software.
– You can use DLP Link glasses to play games in stereo 3D mode only if you have a compatible AMD-based graphics card supporting AMD’s HD3D technology (Radeon HD 5000 series and up) together with the TriDef 3D softare.
– You can use Nvidia’s 3D Vision active shutter glasses together with their specific IR emitter to play games in stereo 3D mode if you have a compatible Nvidia-based graphics card (GeForce 8×00 series and up), you can’t use DLP Link glasses with 3D Vision.
– Have in mind that both AMD and Nvidia have a list of officially supported 3D DLP projectors, so any model out of that list may or may not work, so there is no guarantee that you would be able to use it.
– If you want to be able to play Blu-ray 3D movies then DLP Link glasses are not an option and if you have AMD-based graphics you are out of luck, all of the software players supporting Blu-ray 3D playback on PC such as PowerDVD have support only for 3D DLP projectors using Nvidia’s 3D Vision technology.


3D DLP Projector with HDMI 1.4 frame packaged support:

– You need to use the HDMI 1.4 interface on the projector
– The projector should be either 720p or 1080p native resolution, you will be limited to respectively 720p or be able to use both 720p and 1080p resolutions for stereo 3D, but wit the limitation of using 720p resolution at only 50/60 Hz 3D mode or 1080p at 24Hz 3D mode.
– Even if the projector is with 1080p native resolution, the refresh rate supported at it in 3D mode is limited to 24Hz which is good on for 3D movies, for games you still have to resort back to 720p resolution where you can use either 50Hz or 60Hz in 3D mode.
– With HDMI 1.4 3D DLP projectors you are not able to use 120Hz refresh rate in 2D mode as you can with the frame sequential models.
– These projectors still rely mostly on the standard DLP Link glasses, though there are some models available offering RF glasses as well, but due to the specifics of the HDMI 1.4 3D support the type of glasses used is of not much concern as long as the projector is compatible with them.
– The 3D DLP Projector with HDMI 1.4 frame packaged support do not have support for frame sequential input.
– You cannot use the Nvidia 3D Vision active shutter glasses with these projectors, you either need a generic DLP Link glasses or any other specific model designed for the particular projector (RF glasses for example).
– You can play any kind of 3D videos and movies, including Blu-ray 3D movies as long as you have a software 3D video player and a video card capable of supporting HDMI 1.4 frame packaged output.
– All software players with support for Blu-ray 3D movie playback such as PowerDVD will be able to play 3D movies if you have at least an a second generation Intel Core processor (Sandy Bridge) in order to have support for Intel’s InTRU 3D technology, and this means Intel Core i3, Core i5 or Core i7 CPU, Pentium processors won’t do as they don’t feature InTRU 3D support. For owners of AMD-based video cards the minimum is Radeon HD 5000 series (all AMD HD3D capable video cards should work, though some may not support GPU acceleration for Blu-ray 3D) and for owners of Nvidia-based GPUs the minimum is GeForce GTX 260 or GeForce GT 320 according to Nvidia (some of supported GPUs might not have GPU acceleration).
– When talking about gaming in stereo 3D mode, using Intel’s integrated GPUs is out of the question as they are simply not powerful enough and regarding the AMD and Nvidia-based GPUs the limitation is the same as with Blu-ray 3D movie playback above – you need ca graphics card supporting either Nvidia’s 3DTV Play or AMD’s HD3D technology that can supply HDMI 1.4 frame packaged output.
– Owners of compatible AMD-based hardware with AMD HD3D technology supported need to use the TriDef 3D software (the same as frame sequential users would), owners of Nvidia-based graphics cards need to use Nvidia’s 3DTV Play software (instead of the 3D Vision for owners of frame sequential capable projectors).
– Have in mind that both AMD and Nvidia have a list of officially supported 3D DLP projectors, so any model out of that list may or may not work, so there is no guarantee that you would be able to use it.
– Projectors relying on HDMI 1.4 frame packaged input do tech do have more input lag than models using frame sequential input for stereo 3D and while this isn’t an issue for watching 3D video on them it can be a bit of a problem for some (not all) gamers playing in stereo 3D mode.

You should note that the newer 3D DLP projectors using HDMI 1.4 for 3D support are not suitable for some owners of older Nvidia-based hardware that would work with frame sequential models for example such as the GeForce 8800 which although old is still quite popular and widely used product and quite capable for gaming in the not so demanding 720p resolution even in stereo 3D mode. And with regards to the increased input lag required for the processing of the frame packaged 3D input and the lack of support for 120Hz 2D mode the frame sequential models might still be more attractive for people that are going to be using them mostly for gaming. On the other hand 3D DLP projectors using frame sequential mode are more restrictive and hard to setup for users that are going to be using them mostly for watching movies in 3D whereas the HDMI 1.4 interface makes it much easier. For gaming in stereo 3D mode on a 3D DLP projector there is still not way to get 1080p resolution, so the far that some 3D DLP projectors with HDMI 1.4 interface are with native resolution of 1080p does not help at all as you’d still have to resort to 720p resolution when playing games in stereo 3D mode anyway due to the limited refresh rate at the higher resolution.

DDD is offering a trial version of their TriDef 3D software and Nvidia also does offer you to download a 14-day trial version of the 3DTV Play software from their website, so you can get these to try things out and if everything works then you can buy a license for the software. There is no trial version of the 3D Vision software as it is a part of the Nvidia graphics driver now and it includes only free anaglyph 3D mode, the 3D Vision functionality is tied to hardware requirements as well anyway. If you already have the IR emitter of a 3D Vision kit connected to a PC you get free 3DTV Play functionality, so there is no need to buy a separate license for that.

As you can see 3D DLP projector support overlaps quite a bit in the frame sequential models, though there are some models and brands covered by official support only by either AMD or Nvidia. Unlike Nvidia however AMD is much more open to support for projectors supporting HDMI 1.4 frame packaging as there is no official list of devices on their website. Now, if you already own a 3D-capable DLP projector that is not on the list don’t worry, there is still some chance that you might be able to make it work via a workaround solution, however you should be warned that things like IR emitter emulators, or EDID override drivers may or may not work in your case and even if they tend to work you might face different issues or problems and you never know if they won’t stop working soon. So resort to trying the different workarounds (some of which are also being discussed on this website) as a last resort if you already own a device that is not on the officially compatible list, if you are making the decision on what to buy now, better choose a compatible model fitting your needs and requirements, as this can save you a lot of trouble later on.

The H.265/HEVC Standard is Probably Coming Sooner than Later

January 30th, 2013 · No Comments · Other S3D Tech

hevc-h265-logo


High Efficiency Video Coding (HEVC) or H.265 is a new video compression standard that is being developed by a Joint Collaborative Team of ISO/IEC MPEG and ITU-T VCEG (JCT-VC) for a while already as the successor of the currently very widely adopted H.264 (AVC) standard. The H.265/HEVC has now entered in its final standardization stage and is probably going to be fully approved as a standard very soon, though it will take a while before it becomes widely available in all kinds of devices as the H.264 already is. The final Draft 10 has been presented a few days ago and had received first stage approval (consent) in the ITU-T Alternative Approval Process, so it can be just a month away from getting approved, and a the same time MPEG also announced that HEVC is entering their Final Draft International Standard (FDIS) status which can take two months to have it approved as an International Standard. And if you are wondering why it is important to have the successor of the H.264 standard approved and getting implemented in both software and hardware sooner than later, then you need to think about things such as 4K HDTVs (the standard supports up to 8K), HFR 3D (HEVC will support higher framerates) and other new technologies and products that are going to have more demands in terms of video resolution and storage/bandwidth requirements.

The original idea behind the HEVC is to improve the compression efficiency by a factor of at least two compared to the H.264/AVC compression standard for the same content retaining the same quality and though that goal might not be achieved in all conditions, the results demonstrated from the not yet fully finalized new HEVC compression standard are very promising. Of course the reduction of the bitrate requirements while retaining the same level of quality can only be achieved by increasing the complexity of the algorithms used for the compression and decompression of the video. This means slight increase in the time needed to compress HEVC/H.265 video as compared to H.264, but the decoding process is what will be more performance demanding, especially when going for higher resolutions than 1080p. Of course we are probably going to be getting hardware acceleration for encoding/decoding as well as dedicated hardware made to handle the extra load in devices such as HDTVs.

Now, you may be wondering how is H.265/HEVC going to be important for you in regards to stereoscopic 3D video support. Unfortunately the current Draft 10 does not cover stereoscopic 3D support, though such is going to be available via extensions of HEVC in order for it so also fully support stereoscopic 3D as well as multiview video and other more advanced features such as 12-bit video as well as 4:2:2 and 4:4:4 chroma formats, but we may have to wait until January next year for these extensions to become available. That should not worry you as you are not going to see H.265 available everywhere overnight, it is a process that will take a few years and meanwhile H.264 will most likely remain as the standard, the speed of adoption depends a lot on the industry and how soon H.264 will start hitting its limits a lot, so that the adoption of the successor may be speeded up. But for now we are still at least a month or two before the H.265/HEVC gets its final approval.

Now you can find a lot of similarities here between the H.264 and the upcoming H.265 standard and that is normal as the new one builds on top of the old one and further improves on some features as well as adds new ones. And similar to how the Multiview Video Coding (MVC) extension of the H.264/AVC standard was added as a means to ensure high-quality and resolution 3D video over a medium such as Blu-ray 3D, the upcoming H.265/HEVC will have a similar extension using the Multiview Video plus Depth (MVD) format. The new MVD format is going to be addressing one of the drawbacks that MVC has and that is to be able to provide multiview data for display on autostereoscopic 3D displays in a standardized way without having to increase that much the bit rate required for encoding the additional views. The 3D HEVC extension has been proposed to MPEG and VCEG and was chosen as the starting point for the development of an HEVC-based 3D video coding standard, but as already mentioned this will take some more time. The idea behind the H.265/HEVC and the 3D HEVC extensions relying on MVD is to ensure that the new video compression standard will be future-proof, so it will not only provide features that we are starting to get the need for at the moment, but also support for features that might be required in a few years from now.
