Playstation 3 as a media hub - how good is it? Part IV -- Media Server, capability of streaming media files from computers revealed

 

Finally moved in to the dorm tonight, been stucked in the traffic for 1 hour and a half which normally would only take about 30 min to my school. Plus bad bad weather also, not pouring, but a bit rain during the move-in process which was unpleasently enough... A bit rain is good for Calif though since I don't remember when was the last time there was raining this yearSad

So let's move on to my Playstation 3 review which I've been promising supposedly to post on 09/19...

So this time is about streaming media to Playstation 3 from your DLNA enabled devices such as a computer. This is a new function added after firmware v1.80. This is a huge improvement on what the PS3 is capable of in terms of as a media hub IMO. Prior to v1.80, if you want to get your media files to play on PS3, you only have 2 (maybe 3) choices:

1. Burn a disc, then play in PS3

2. Copy files to hard drive (FAT32 only, 4GB file size limitation) or other flash media, then playback on PS3

3. Using the software, Red Kawa fileserver, to download files from your PC to PS3, but the speed is amazingly slow...

So after v1.80, you no longer have to do the above, just streaming from your computer using an DLNA enabled software, that's it. The speed of the streaming is amazingly fast on a wired connection, a recorded 1080i around 14Mbps mpeg2 file starts instantly at the time you hit your play button, and there's never a drop out. So it's really good, but people have reported slow connection on the wireless side since PS3 only has a 54Mbps card. By using this function, you also break the 4GB file size limitation on FAT32 drive, and there's NO folder/file name restrictions whatsoever. The bad side is that a PS3 is still a PS3, it only recognizes very limited files, videos have to be mpeg with mp2 (if other audio such as ac3 the mpeg has to be program stream) or mp4 AVC, no avi, mkv, ogg stuff. But you can use a DLNA enabled software called TVersity to transcode those non-compilant video formats on the fly. A very impressive software to further extends the ability of PS3. But since I don't like anything being compressed, or transcoded, the software is no big deal to me, but I'll introduce it briefly later. Another problem presently presents is the audios in HDTV gets converted to LPCM on PS3, seems like SONY likes LPCM a lot... This is not a big deal on casual viewing, but if you have some good surround mixing TV shows, you are just missing out those effects. And PS3 seems adds a lot of bass on the converted audios which results an over-exaggerated boom, very unnatural. Yet the biggest problem I found out is that PS3 can't handle certain mpeg2 stream, such as those records from CBS and the Tube (a 24 hr digital music station here). There's this guy who has the same problem, here is his blog entry about this issue, he puts out this file for diagnosing purpose. My summary ends here, I'm impressed how long I can write here... But this never happens when I write a research paper...

So let me introduce the media server function picture by picture. The following is a setup on the network. The last option media server connection is where you can enable/disable this cool function...

Media Server Connection Option

There are many DLNA enabled softwares you can use, I'm using windows media player and Tversity here. Windows media player is the easiest way to go since it's already in windows, but it doesn't support mp4 AVC. I would recommend TVsersity here for mp4 support, or even trancode on-the-fly for non-compilant avi, mkv, etc files.

Turning on Media Sharing function in windows media player, it'll recognize PS3 easily as Unknown Device, check allow then you are all set.

The interface of TVersity, ustilizing flash. TVersity is very powerful at updating the media, not only sharing to PS3, but can also share to other device such as PCs. Much more powerful than windows media player. The setup of TVersity is a bit hard at first, you can check this blog entry for detailed instruction, also check out TVersity PS3 forum

Basically, if you setup the softwares correctly, PS3 will recognizes those servers immediately, but just in case something doesn't get updated promptly, here's how you can manually search the servers...

Loosen your seat belt, cuz searching takes a long long time...

So first let's entering the TVersity server

Blackhawk Down Trailer I copied from PS3 to PC, just to test the ability of supporting media on TVersity.

Tom and Jerry tale I recorded from Saturday morning cartoon, the original capture is 1080i, here I have encoded to x.264 using Megui. The reason I chose to transcode this one is that the original source is a complicated one, most of time are fast motion chasing scenes, so I think I made a bad choice later on after I waited 24 hours for this 20 min footage to compete encoding process... The result is NOT very good, the picture gets residues from previous scenes, very weird... Side notes, I just wish that WB and UPN the two never got merged together, that way I got some more cartoon like transformers every afternoon on WB and more si-fi on UPN.

Here's some of the parameter I set in Megui... I set the bitrate @1Mbps, and audio as AAC-LC multi-channel... This is the native resoultion 1024*768 on the screen.

Another picture shows that the time searching function is working on the mp4 file, so except slow encoding and ghost pictures, Megui really gets the job done. I might look into it further when I got time since cartoons I don't really care too much about image quality, they are NOT HD anyways...

Now come to the windows media server, which has more files...

Lots of Channel 2 recordings, but ironically, PS3 can't handle any streams from this channel...

83d4c8c5.jpg picture by linkai8424

Cold case, a crime investigation type drama I recently got interested in...

CSI Miami, love the warm vivid pictures, and the surround sound mixing, but too much noises...

15ef06ea.jpg picture by linkai8424

Heroes, don't like the show, can never understand why it has such a hugh success... I am experiencing recording time on how to record two different shows on a consecutive time but not losing any content on both, such as here the heroes is from 9:00 to 10:00, then CSI Miami starts from 10:00-11:00.

Here are the most troulesome mpeg2 files. All the shows from CBS and the Tube aren't playing correctly on the PS3. My favorite show Jericho happens to be the worst of these mpeg2...

This Spiderman3 theme song doesn't get any better...

Complete Mai-K TV works fine though... I guess the goal for completing this series is where I start my downloading career...

a01e569c.jpg picture by linkai8424

So no longer have to burn DVD-RWs to watch them...

2c51bf2a.jpg picture by linkai8424

Screen mode can be used to change the size of the window, like the original window, extend to the full screen with some horizontal stretch for 16:9 non-anamorphic material. Original 352*240 windows on 1080i screen, how small it is...

7d6f853c.jpg picture by linkai8424

Windows media player doesn't have the ability to transcode non-compliant files, so shows a bunch Unsupported Data here, these are actually avi files I believe...

Mai performs her Japanese debut song "Love, day after tomorrow" on 56th NHK Kohaku show in 2005. Her 3rd apperance on this show. In 2006, she did her own countdown live...

This is a crippled 1024*576 version, too bad, still havn't got the 1080i version with AAC 5.1

Playstation 3 as a media hub - how good is it? Part III -- DVD/BD related settings and DVD upscaling capability on firmware v1.9x Part 2

 

71224f47.jpg picture by linkai8424

This entry is a continuation to the PS3 settings post, it focuses on the upscaling feature on the PS3.

Since I'm using  a component cable, the only way I can take the advantage of PS3's upscaling feature is to burn a DVD-R. Frankly, I only have very few DVD-R backups. The DVD-R I will be using here is Blue Gender, the anime series I reviewed not long ago. The original DVDs are D5 around 4G in size, so backups are easy, therefore I made them, but generally speaking I don't make copies...

So here upon inserting the disc, PS3 recognizes as DVD-R, upsacling will be applied.

a1ae105a.jpg picture by linkai8424

If you press the green triangle button (options) on SIXAXIS or BT remote, it will show the options, here there are four. You won't get the fourth item "Information" if you are using a copyrighted disc or DVD-ROM.

80faf28a.jpg picture by linkai8424

The infromation is very basic, only shows the number of titles... I wish it shows the size of the disc...

097c3fe0.jpg picture by linkai8424

So this is a random disc I pull out, the second disc of the anime series. This is how upscaling looks. I think this is the best picture I took in this batch.

893ae261.jpg picture by linkai8424

Earlier I mentioned how I check if upscaling is applied, this is the picture, my monitor truly shows 1080i.

b983fb35.jpg picture by linkai8424

Move on to the DVD playing GUI, which is very similar to blu-ray disc. The top shows the title number, audio codec and bitrate, video codec and bitrate; the bottom is the timeline. These icons are also very similar to blu-ray's, it's just blu-ray disc has those red, green, blue, yellow buttons which the DVD doesn't have here. The only picture quality related settings you can access here is the AV settings, it's the second row second icon from the right (the icon right underneath number 8 and 9 and between them with two sliding bars horizontly placed, forgot to take this picture... )

28dde1d9.jpg picture by linkai8424

Activating the AV settings, you get frame noise reduction, black noise reduction, and the method of Upscale. The noise reductions are effective at removing the noises, but on my monitor, I saw some annoying horizontal shaking lines during some scenes. Other than that, upscaling is perfect. I think the default value for both reductions are 2, choosing 3 can elaminte that horizontal shaking lines a lit bit.

There are four methods of Upscale: Normal, Double scale, full, off. The default method is Normal, as seen here. It automatically corrects the aspect ratio. Traditional DVD players with upscaling don't provide auto aspect ratio function so every time you want to watch 4:3 footage on a 16:9 screen with non-distorted image, you have to manually correct it. So PS3 is the only machine I've reviewed so far provide this feature except those DVD software  on computers... I think it's a very very good feature, saves the time switching back and forth if you want to watch 16:9 feature movie and 4:3 bonus material.

8a404797.jpg picture by linkai8424

Double scale is the same as Normal but shrinks the overall picture by about 10%, and it's only working under 1080i/1080P resolution, does NOT work on 720P.

cb9b2d19.jpg picture by linkai8424

Full is remove that aspect ratio correction feature, which I think is NO good. Here is the team leader battles with an early stage blue which has its core exposed in air, knock off the core, then the blue is dead. Later evolutions on the blues have shields on the core or gets buried within their body, the scientist on the second earth developed a new type of machine called double edger which can effective kill those kinds. The very last blue they battled with does not have a core...Thinking

ab494dff.jpg picture by linkai8424

Off is turning off the upscaling feature, which results a softer image and loses the auto aspect ratio correction feature.

7fabe466.jpg picture by linkai8424

Finishing up the intro for the upscaling, here is a Copyrighted disc, Dark Angel Season 2. Non scaling is applied as detected by my monitor, 480p only.

Jessica Alba (Max) gets distorted...

9879974f.jpg picture by linkai8424

Have to manually forcing 4:3 aspect ratio.

55d19c6f.jpg picture by linkai8424

Sum up, the upscaling feature on PS3 is very effective, it provides a much vivid image than original DVD and auto corrects the aspect ratio. Only quirk is that some weird horizontal shaky lines are introduced during some scenes on Blue Gender, I haven't checked out non-anime material yet. DVDs without upsacling are about the same picture quality as my Harman Kardon DVD.

Last, PS3 has no problem displaying my authored "advanced“ subpicture, this DVD took me about 4 weeks to finish, including adding transition menus to the original menus, adding a feature page, making about 1800 subpictures by copying and pasting from the net and timing them according to the songs, competely re-programming the structure and registers in the DVD, a huge huge project I have ever done.
