I'm in the envious (or otherwise) position of beginning creation of my video library. Lots of DVDs, about 30 BDs, and a fair amount of home video. For the optical media, I will need to encode to a suitable file for streaming. I've experienced some audio (and to a lesser extent video) stuttering with an avi file I have that plays perfectly from serviio to my xb360. I've read there are high-bitrate issues with the sony players, but I have another video that I encoded with the same output parameters (in handbrake for playback on a nookcolor, actually) that has no issues on my BX37 (S370).

So, about to embark on encoding my collection and would like to get the best quality I can on the BX37 without any stuttering issues. My serviio is running from my synology NAS (1.2GHz ARM CPU), so serviio transcoding will likely not be an option for me. What file types/bitrates have worked the best for those with sony DLNA products?

Compare bitrate of these two movies with Bitrate_Viewer

It is very difficult to answer.
- Best container, probably MKV but not supported with all DLNA products, best Sony container seems to be MPEG2-TS limited to 20-25Mbps bitrate.
- Best Audio encoder is DTS but AC3 must be preferred ( 2channels with 192kbps, 6 channels with 384kbps)
- Best video encoder is x264 (AVC/H264) maximum 1920 x 1080 resolution, you could probably set the maximum video bitrate to 15-17Mbps.

What is the reason Sony DLNA limit to 20-25Mbps bitrate?
With this bitrate may only play video as 720p
Correspondingly, watch videos 1080p is not possible because the bitrate in that video is much more than 20-25 Mbps

Posted: **Tue Jan 17, 2012 10:03 am**

20-25Mbps bitrate is the DLNA "conformance" value, but device could support more. Example:
- MPEG_PS : 10Mbps with mpeg2video (like DVD)
- MPEG_TS_SD : 15 Mbps with mpeg2video
- MPEG_TS_HD : 20 Mbps with mpeg2video
- MPEG4_P2_MP4_SP_L5 : 10 Mbps with mp4 video
- AVC_TS_MP_HD : 25Mbps with avc/h264 Main@Level 4
- AVC_TS_HP_HD : 30Mbps with avc/h264 High@Level 4 --> The best formats/bitrates for Sony DLNA

But you could fing a system transport bit rate up to 48Mbps.

EDIT: There were also VC-1 video codec with Advanced profile Level2 (20Mbps) and Level3 (40Mbps), http://wiki.multimedia.cx/index.php?tit ... And_Levels, but L3 is probably not DLNA compliant.

How can this be accomplished?
network of 100 Mbps is sufficient for this purpose or need gigabit network?

I'm talking about the MPEG2 Transport specification, in real life renderers use 100Mbps Ethernet interface, and firmware video decoding (buffer) are probably limited (30-35Mbps).

firmware video decoding (buffer) are probably limited (30-35Mbps)

this restriction only Sony TV DLNA? Or from other manufacturers such as restrictions (Samsung, Toshiba, etc.)

only one example:

avatar, no stutter, the film plays perfectly! no difference with blu-ray disc. (sony bdp-s780, no trancoding, lan cable)

sony bdp-s780 - this is not TV

I am interested in a direct connection to TV and DLNA network without intermediate devices (players, WD tv Live, etc)

Do you like the player is connected to the TV?

Thanks for that screenshot.

You confirm this mkv file is a direct BlueRay Ripping ?
The peak @50Mbps is strange but all other bitrate <40Mbps seems good.
mkv is not specify in DLNA, probably in the next version 2.0

they mean a big difference it is?

this is a direct connection.

PC-> DLNA -> BDP-S780 -> TV

I understand correctly that the current version of DLNA is not able to play files of more than 25 Mbps
1080p playback of video files with a bitrate of more than 25 Mbps will be supported in version DLNA 2.0
This applies to all producers of the TV or just to Sony ?

When a new version of DLNA 2.0 ?

ok, but serviio it plays perfectly.

http://en.wikipedia.org/wiki/Blu-ray_Disc#Bit_rate

Bit rate
For users recording digital television programming, the recordable Blu-ray Disc standard's initial data rate of 36 Mbit/s is more than adequate to record high-definition broadcasts from any source (IPTV, cable/satellite, or terrestrial).
BD Video movies have a maximum data transfer rate of 54 Mbit/s, a maximum AV bitrate of 48 Mbit/s (for both audio and video data), and a maximum video bit rate of 40 Mbit/s.
This compares to HD DVD movies, which have a maximum data transfer rate of 36 Mbit/s, a maximum AV bitrate of 30.24 Mbit/s, and a maximum video bitrate of 29.4 Mbit/s

Sony have probably made some progress on DLNA with 2011 BDP devices, not sure that mine (BDP-S370) supports that bitrate (not tested, no sources)!

thanks, Illico.

I'm an even higher bitrate test. then I sign up here.

For future DLNA Guidlines version, I don't know ... don't have 500$ !

All producers Sony, Samsung, Sharp, Panasonic are DLNA members.
But Sadly, some providers haven’t adopted 100% DLNA’s streaming guidelines (LG device), but other adopted 200%.

eclp results on Sony device are very encouraging.

Do not want to seem annoying or modest

In colleague at work TV Samsung UE32d65XXX
He argues that the TV plays fine on 1080p DLNA video - respectively bitrate in this file more than 30 mbps

I updated my firmware to the new TV

Now that the file I pointed out earlier 1080p plays perfectly.

About this upgrade (18/01/2012)

This file updates your TV set firmware to version PKG3.904EUA, and provides the following benefits:
Improvements in this version:

Improves TV performance during 1080i / 1080p transitions

I too noticed stuttering using a Sony BDS-580. Some files play perfectly using wired connection, and some stutter.
Files that stutter that will fit on a 16Gb USB flash drive (or have been cut down to test) play perfectly when plugged into the player, so the file itself is not the problem - MKV, TS and M2TS tried. They also play perfectly using my PC and Media Player Classic.
I had noticed that movies encoded with the latest TRUE-HD and DTS 7.1 were worse. The Sony reports file playback rates at just under 40Mb/sec during peak times, which is well within my network capability. Tried transcoding to lower audio using TsMuxer, but that didn't work either.
I also tried other free DLNA software (none I found were any good) and Mezzmo, which is priced! Mezzmo couldn't handle these files either, even with their own transcoding methods. Their support advised there was a known problem with Sony and DLNA at higher rates and have developed transcoding to supposedly deal with this by limiting the stream rate to 20Mb, but this didn't work for me either.
As an aside, Mezzmo does things a lot better than Serviio! It is easier to use and a lot faster in loading, updating files etc. This is not a plug for a free version - I didn't buy it as I couldn't get it to work with the stuttering files either! - but for some users I can see it would be a lot better than having to nursemaid Serviio all the time.
Does anyone know of a file I can try that has a known constant bit stream which could be adjusted? I was thinking of trying some increasing bit rates until stuttering occurs, in an attempt to know if it is worth limiting the video or audio rate, or both.
I also wonder if the problem is inherent in the files themselves, perhaps dodgy encoding techniques, simillar to some MP3 problems.
Does anyone know of a good way of testing this?
