pcHDTV HD-5500
The pcHDTV HD-5500 is an ATSC PCI card. This is the third, and most recent, product offering from pcHDTV.
The card's nomenclature falls slightly out of line from its earlier product offerings (the HD-2000 and HD-3000). It is quite possible that pcHDTV would have liked to have used "HD-5000", but ended going with HD-5500 due to the fact that BBTI/TechniSat had already released a card to market bearing a "HD5000" moniker. Undoubtedly, in using "HD5000", BBTI/TechniSat was in part capitalizing on the prevalent marketing hype for the "LG 5th Gen" demodulator. Nonetheless, its interesting that they choose a nomenclature that is also quite similar to a competitor's (pcHDTV) conventions.
