Max Bitrates for USB content on Philips DVD Players

[GrayStrickland]

I'm hoping Jagabo will jump on this thread....

It's been posted that the maximum bitrates for USB content on a Philips 5982 is 3000 kb/sec (or 3 MB/sec); and that the 5982 has only a USB 1.1 port.

It's also been posted that the Philips 5990 and 5992 have a USB 2.0 port. With a faster usb port, I wonder what bitrate they can handle from usb. What is the maximum bitrate for USB content on a 5990 or 5992?[/u]

Since the USB2 port and processing chip on the 5990/5992 limit file resolution to ~720x576 (MPeg, Divx, Xvid, WMV codecs), I'm wondering how one would test bit rates over ~8-16 Mb/s (1-2MB/s). Can you suggest a test file? I have a 5992.

BTW, USB 1.1 is limited to about 5Mb/s in continuous transfer.

I just tried a 720x480, 24 fps, 9500+ kbps CBR Xvid, plus 384 kbps AC3 audio AVI on an 8 GB thumb drive and had no problems. 8000 kbps and 6000 kbps also played with no problems. I had to lower the motion search precision settings and use no b frames to get the bitrate up to 9500. Actually, I had the encoder set for 10000 but the file came out 9500 (reported by GSpot which scans the video data). You're going to have a hard time getting Xvid bitrates over 10000 kbps with standard definition video.

The 5982's limit is probably more like 4000 kbps. I had a 5960 and it played a 3000 kbps CBR Xvid plus 384 kbps AC3 file properly. But if I stepped up to 4000 kbps for the video it started getting jerky. From reports* from people with the 5982 the limit looks to be the same or a little bit higher.

<edit>
I just made a 20000 kbps CBR xvid video from a very noisy source. It was only 30 seconds long and had 256 kbps MP3 audio. It played without problems.

Consider a Western Digital TV HD Media Player. It costs about US$120 but can play high def and a much wider array of containers and codecs.

* There is a thread here that was started when the 5982 was just coming out. Philips' web site claimed something nebulous about it like "compatible with USB 2.0 devices". So there was a lot of discussion about whether that meant USB 2.0 or not. It was eventually determined that the player's USB performance wasn't significantly better than the 5960.
