For PS3-loving gamers without any technical knowledge of video formats, this is some rather good news. Simply put, there's now an app that will let you change the format of videos into the ones used by Sony's PlayStation 3.

Red Kawa is a new company that just opened up shop this month, but they're offering an app meant for something a lot of people don't have yet. That's a lot of preparation right there. This new video formatting programmed is called the PS3 Video 9, and it turns the videos you have, whether they be WMV or AVI or whatnot, into your choice of the following PS3-playable formats:

MPEG-4 SP (AAC LC)
H.264/MPEG-4 AVC Main Profile(AAC LC)
MPEG-1 (MPEG Audio Layer 2)
MPEG-2 PS(MPEG2 Audio Layer 2)
MPEG-2 TS (MPEG2 Audio Layer 2)

If the name of the program sounds familiar to PSP users, then your assumption is also quite right. The PS3 Video 9 was also developed by the developers of the PSP Video 9 app. In fact, they also made the beloved email program known as PSPoste. Now that they've made a company though, you're sure to hear more from these programmers in the coming months.

Perhaps the best news of all about PS3 Video 9? It's free. Just visit their site for a download, and send them some love, alright?

Ayer SDI DVDP connect to Miranda and Teranext video scaler HD-SDI output and HD-SDI to 5BNC output and CRT projector.
Best PQ is Ayer SDI , next is A1VX, next Sony PS3 ,next Merdian DVDP.
Ayer and A1VX have better dynamic range and less video noise.
Wow!, PS3 is a good DVD player. I like this PS3
As you know, Merdian and Ayer DVDP is very expensive.

I just set up my PS3, popped in the DVE DVD, and went to calibrate. Using HDMI, the PS3 won't pass BTB. WTF? Any clues?

Vill heslt slippa linux då jag har dåliga erfarenheter av det tidigare.

Förstår inte hur de har tänkt med ps3. Hur ska man få in filmerna på hårddisken om man inte kan koppla den till en pc på ngt sätt. Jag syftar på utan linux. Vill heslt slippa linux då jag har dåliga erfarenheter av det tidigare.
Verkar som de vill man ska hålla på och flytta usb-diskar eller bränna film på skivor.
Kan inte se hur den här ska kunna vara bättre än en vanlig HTPC eller en 360 för den delen. Snarare omständigare.

Klarar PS3 av AVCHD-DVD skivor?

But perhaps even more significant is that aforementioned late-breaking issue surrounding the PS3's resolution upconvert/downconvert problems. Sony has confirmed that the PS3 does not upconvert 480p/i and 720p content (whether a standard-def DVD or a PlayStation game) to 1080i, instead only upconverting to 1080p. That leads to two separate issues. First, if you have a 1080i-only HDTV, it is up to your monitor to upconvert the 480p/i or 720p output from the PS3 to 1080i. While that puts the PS3 a rung below most next-gen disc players, which usually upconvert lower-res sources to at least 1080i, I don't know if it's a true deal breaker. Far more problematic is if you set the PS3 to 1080i output mode to work with your 1080i-only monitor, the PS3 will then downconvert 720p content to 480p. That's right -- the PS3 can only output 720p content as an 1080p upconvert, as native 720p or as a 480p downconvert. Since there are still a wealth of 1080i-only HDTVs out there, as well as a host of 720p native PS3 games hitting the market, that's a big drawback for the PS3. Sure, most 1080i sets also accept native 720p signals and will upconvert to 1080i internally, but not all. Why Sony just didn't allow for both 1080p and 1080i upconversion is a bit of a mystery. We can only hope that a fix is possible via a software update and that it is not a hardware issue. Of course, I'm fully 1080p-capable, so I had no such problems. But not everyone is so lucky.

Jo den kirrar 1080i ut.

Ett krux med att ha den inställd på 1080i (vilket man vill på BD film om displayen saknar 1080p-support) är att 720p material (spel då tex) kommer skickas ut som 480p(576p här kanske). That sucks, värdelöst om man måste ändra beroende på om man kör spel eller BD. Hoppas (och tror) på firmware upgrade.

Sony vill väl att vi ska köpa 1080p-input kapabla tv-apparater, I guess.

Hmmm... Stämmer verkligen detta?
Är det inte så att den drar ner det till 576p enbart i de fall som apparaten saknar stöd för 720p?

Sony America has acknowledged that there's a problem with upscaling on the PlayStation 3 in its current form, and has pledged to fix it.

Basically, some older HDTVs are happy to do 1080i (interlaced, 1920x1080 resolution) but not 720p (progressive, 1280x720 resolution). The PS3's reaction to this ought to be to "upscale" the 720p image so it's what the 1080i user sees.

However what actually happens is that the PS3 kicks out a 480p image, meaning that people's televisions are left displaying what amounts to not much more than a PS2-size image.

(To put it another way, these people reckon they should be seeing 921,600 pixels, but in actual fact they're only getting 408,960. And they want those extra 512,640 pixels, boy howdy.)

Sony says that this lack of upscaling happens because the television itself needs to have a 720p input in order to display games that don't support the higher resolution 1080p (progressive, 1920x1080) image. (It's good to see everyone's trying to make this simple and easy to comprehend, isn't it?)

"This is an issue on the side of the individual television sets," a statement from SCEA confirms, "which do not accept 720p input, so when a game outputs an HD signal only at 720p, these select TVs have to display the game at 480p instead."

All of which gibberish, however, can be happily set aside given that Sony's working on a solution that will be rolled out in a forthcoming firmware update.

Just nu plågas de i Nordamerika av att deras tv som endast klarar 480p och 1080i (spec de äldre) och Ps3 skalar då ner ett spel som är i 720p till 480p. SONY har lovat att det skall fixas via uppdateringar.

Jo, men det är enbart på spel detta problem uppstår, och den här tråden handlar om film...

<{POST_SNAPBACK}>

men paccis, om man har en 720p projektor eller tv, vill man då inte ge ut signalen från ps3 i 720p då(och inte 1080i?)?

eller blir det bättre å skicka ut en 1080i signal å sedan låta projjen göra om det till 720p?

Video Modes
The PS3 uses a set number of video modes, denoted by number rather than by resolution:
0:auto mode
YUV
60Hz 1:480i 2:480p 3:720p 4:1080i  5:1080p
50Hz 6:576i 7:576p 8:720p 9:1080i 10:1080p
RGB
vesa 11:WXGA 12:SXGA 13WUXGA
60Hz 33:480i 34:480p 35:720p 36:1080i 37:1080p
50Hz 38:576i 39:576p 40:720p 41:1080i 42:1080p

I was planning on putting the PS3 in my mini theater and the [Panasonic] BD-10 in the main theater. Given the results, I will swap them.

Set the PS3 to output 1080p and also select 1080i. The 1080p is not created by using a deinterlacing chip like the Samsung and Panasonic. It just does a 2-3 frame repeat of the 24p pattern. This means it will never drop out of film mode.

I'd also like to add to my post above that if I select multiple resolutions for the PS3 (720p and 1080i) it will correctly go to 1080i during BD playback. But, in the PS3 menu's it goes to what it thinks is a better resolution, which is 720p. If I want to view 1080 on the menus too then I have to remove 720p entirely as a display option.

I can confirm this. These "symptoms" are exactly the same on my setup. BD movies kick to 1080i, but the menus and games go to 720p.

You can tell it what resolutions your television accepts. This is quite different from telling it what resolution to output.

The end user (at this time... could be fixed via firmware update) has no control over what the console actually outputs. The problem stands that if one selects 1080i, then the system will boot and load the XMB (system menu) in 1080i. The instant that person selects a game (or other source) that is 720p, then the system will down-res to 480p - because you don't have 720p selected as an available output.

If one selects 720p as an available output option, then the system defaults to 720p, regardless of what other selections they've made. The system will properly switch to 1080i for Blu-ray playback. It will also switch to 1080i for games that support 1080p (or i) resolution, such as NBA '07.

I know this sounds confusing, so I have one more trick up my sleeve... Here's how my PS3 is configured:

Available resoluitons (the resolutions I've selected as being available) - 1080i, 720p, 480p.

Actual output:

XMB (stands for Cross Media Bar - The system's main menu) - 720p
Motorstorm Demo - 720p
NBA '07 Demo - 1080i
Resistance: Fall of Man (full game) - 720p
Black Hawk Down trailer (downloaded content) - 1080i
Talladega Nights: The Ballad of Ricky Bobby - 1080i
X Men 3: The Last Stand - 1080i

For comparison, here's the actual output if I only select 1080i:

XMB - 1080i
Motorstorm Demo - 480p (looks like crap, too!)
NBA '07 - 1080i
Resistance: Fall of Man - 480p
Black Hawk Down trailer - 1080i
Talladega Nights: The Ballad of Ricky Bobby - 1080i
X Men 3: The Last Stand - 1080i

It simply won't upsample 720p content, so it down converts the signal instead. This is what you may have read about in other forum threads... People with older HDTVs that don't support 720p resolutions are pretty much screwed.

- Since the standards for BD-ROM such as BDMV and BD-J were delayed, particular player functions were developed later while 2 years has already passed for the development of software decoding function for codecs such as H.264.
- H.264 decoding itself was not very difficult for Cell with moderate optimization and they could play a movie in realtime at the first try unlike very difficult SACD optimization. However, because they began the development without knowing the final Blu-ray standard, they set the goal very high for decoding 2 full HD H.264 streams at 40Mbps simultaneously. Besides the clockspeed of the devkit was lower than the final product which made the development difficult. The current decoder can decode full HD H.264 with 3 SPEs.
- The current BD/DVD player for the PS3 does internal pixel processing at 16-bit per RGB. (The output depends on the display color depth.) Though the 1.0 firmware was 8-bit per RGB, Kutaragi ordered the change of the design at the final product review and it was upgraded to 16-bit in the 1.1 firmware.
- It's still not enough for TV and theater projectors that can display the original YCrCb stored in BD and DVD. For example the current PS3 player lacks gradation in brighter and darker parts of pictures when compared to Panasonic DMP-BD10. The reason why the internal processing is done in RGB is because RSX can't have 2 color spaces at the same time. Honda suspects they used RGB for the player because in the prototype design they planned to overlay XMB in RGB onto the picture of BD/DVD. In the final design XMB is not overlayed onto the player.
- Actually Kutaragi also ordered the development of the version with YCrCb internal processing at the final review. In the firmware version released in December it becomes possible for a user to choose RGB or YCrCb.
- The current player converts interlace to progressive only for SD movies. Right now SCE developers are working to improve DVD picture quality after they implemented YCrCb. After that it's planned to do something for 1080i to 1080p conversion. Though the RAM size can be an obstacle for it, SCE developers say they can do it by splitting the load between Cell and RSX.
- Currently there are complaints from users about non-existent DVD upscaling in the PS3. As for the interlace-to-progressive before upscaling, the current player has it already. There was a team at the division for broadcast equipments at Sony that does research for improving image quality by using the NVIDIA shader language. They ported it onto RSX. After Cell does noise reduction and other filters, RSX does interlace-to-progressive conversion. Though the current algorithm has bugs for some video sources, SCE says the conversion precision will be upgraded by future updates. Also the noise reduction filter is currently optimized for video sources with relatively many MPEG noises recorded with a video recorder. SCE knows lack of picture details because of it and will provide new default values for noise reduction by checking recording formats and media IDs for DVD discs. As for upscaling, they are doing the research to develop a high-quality multi-tap upscaling filter that balances the load between Cell and RSX. They also plan to use the non-original luminance information generated in upscaling for HDMI 1.3 deep color.
- Currently it's known that the audio quality of DTS is especially good compared to other audio codecs as heard in playing 480p DVD via HDMI with more bandwidth for the audio. SCE don't know the definitive reason. They just ported the reference source code provided by DTS with as high precision as possible.
- An SCE developer recommends trying 1.5x fast-forward playback in the PS3 BD player to see the power of Cell. When it's connected to a display via 1080/60p, it becomes very smooth as Cell has an enough margin for video decoding. In 1.5x fast-forward playback it decodes all frames then inserts them into 60fps with sped up audio.
- SCE declared that they'd support 1080/24p in the PS3.

- Though PSX (the DVD recorder) was too weak to decode SACD in software, it was expected that the PS3 would be able to. SCE began the development in a relatively earlier stage. But even at the beginning of this year the SACD decoder was 6 times slower than realtime to convert surround DSD sound into PCM.
- The manager of the Software Platform division at SCE who were in charge of software codecs and players estimated it'd be impossible to finish if they kept that pace. A developer from the Sony HQ who developed softwares for VAIO PC came to SCE and they assigned the development of an SACD decoder codec to him.
- SACD is stored in the DST format (= compressed DSD). DST changes compression methods and parameters every 1/75 seconds, which eats huge processing load when decoding. In the first 2 months the developer optimized it into realtime processing. Then he threw away the old source code and wrote a faster new codec in 3 weeks with the knowledge he had gained. It uses 5 SPEs - 3 SPEs for DST decompression, and 2 SPEs for DSD to PCM conversion.
- After that, he debugged it while consulting the professional audio equipments division of Sony that
developed the DSD format itself. It took 6 months.
- Then the audio tuning specialist at the audio division of Sony began to use a PS3 to check the sound of the then unreleased HD receiver TA-DA3200ES. He pointed out where to fix in the PS3's digital audio processing to SCE. It was in the early October, and the dynamic range at that time was 140dB which was the initial goal set by another Sony developer who developed DSD. The PS3 firmware version 1.10 is this version with a few updates. The decimation filter of the SACD decoder outputs at 24bit/88.2kHz.
- However, last Friday, Honda went to a place for the interview with Ken Kutaragi for some audio/videophile magazine. They brought there an even newer version with a decimation filter at 24bit/176.4kHz. Also, the 64-bit DP internal data of the decimation filter is rounded down to 30-29-bit instead of 24-bit for the output. The dynamic range is over 170dB and the theoretical number reaches 180dB in 30-bit. Honda says its sound was really good even when compared with the sound of the 1.1 version firmware. The Sony developer attributes the goodness to the fact that the software SACD codec of the PS3 processes all data in 64-bit double precision. This new firmware version will be available when the BD remote is released in December.
- As for improving CD sound, upsampling is apparently easy by writing a FIR filter. But it is not yet in the PS3 software player as it takes some time to choose an appropriate upsampling function and noise shaping algorithm.
