Well, I've reverted to using Linux (Fedora Core 6) and have found the experience much more technically involved, but also much more flexible and functional. Linux V4L2 and IVTV allow for granular control over the WinPVR-350 boards, and will allow multiple boards to be used in the same system. Now my...

I am testing a solution now using WinPVR-350 boards, which rely upon the same video4linux driver that the 250 boards use. I've tried using multiple cards under Windows accessing via DirectShow, but have found that does not work due to DirectShow limitations. My understanding of this same solution un...

I am trying to build a system using VLN and Hauppague WinPVR-350 PCI MPEG2 encoders. Each WinPVR-350 has two analog video encoders onboard, and I have two WinPVR boards installed for a total of 4 encoders. Both of the hardware devices are referenced in DirectShow as "Hauppauge WinTV PVR PCI II ...

When setting up terrestrial broadcast encoding systems, we implement fairly stiff forward error correction on our UDP stream to eliminate the need for retransmission. Not sure if this is applicable to your needs, but I'll tell you that it works very well us. Note that FEC in these encoding systems i...

Only digital transport streams, such as 8VSB ATSC, COFDM DVB-T, and other similar transmission standards, may be decoded to individual program streams each handled seperately. That is because the transport stream is on a single carrier frequency. In analog, a single carrier contains a single program...

I am attempting a similar build but am having problems referencing the encoders within directshow, since they each have the same description. I am able to successfully begin one encode/transcode/streaming operation with one board, but subsequent attempts will crash VLC. I can only access one encoder...
