Yes, USB is the bottleneck. The Divicatch tops out at about 80 Mbps (just capturing to disk) on my Dell 2.6 GHz PC at work. Fine for broadcast streams, but not so good for content distribution where some folks want to do I-frame only 4:2:2 HD MPEG-2 at 150+ Mbps. Ron John Willkie wrote:
I guess I need to ask Regis about Enensys' plans for M/H support on these units.As to the studly PC, that's mostly due to the USB interface, and I suspect that the upper bit limit on DVB-T/H would prevent that from being much of an issue. Even SCTE transport streams aren't usually above 38 mb/sec.Even the Dektec PCI cards (which do less hardware processing than do the DVEO/Computer modules hardware cards) have no problem rendering a single program service on my 2.66 ghz single core Celeron box. USB is a whole different matter, though.John Willkie------------------------------------------------------------------------*De:* opendtv-bounce@xxxxxxxxxxxxx [mailto:opendtv-bounce@xxxxxxxxxxxxx] *En nombre de *Ron Economos*Enviado el:* Saturday, December 13, 2008 4:40 PM *Para:* opendtv@xxxxxxxxxxxxx *Asunto:* [opendtv] Re: Can't stream HD?The Enensys Divicatch ASI works with VLC. In fact, there's a copy of VLC on the Divicatch installation disk. Of course, you need a truly studly PC to play back high bitrate streams. http://www.computermodules.com/usb-transport-stream-capture-playback-analyzer/DVB-ASI-Capture-Playback.html Ron John Willkie wrote: And, I should point out, I know of no plug-ins for Windows Media Player or VLC that provide this functionality either. Part of the problem is the "up to 216 mb/sec" nature of DVB-ASI. Much simpler to figure out which program service within the transport stream to render than to process the entire transport stream. That's what non-professional gear does. What you are referring to is the creation and analysis tasks of the 1990's,and in non-broadcast environments.In broadcast environments at least, they are much different these days, and DVB-ASI (and to a small extent, SMPTE-310) are simply required.
