USB flash drive. They have support for analogue and digital terrestrial TV. The HVR-9xx sticks are produced in Taiwan by Deltron, and are also sold for Apple computers by Elgato under the EyeTV brand. HVR-1xxx devices are PCI-based products that receive analogue and digital terrestrial TV. They are similar to the HVR-9xx but have support for NICAM or dbx Stereo for analogue terrestrial on all models. HVR-3xxx and 4xxx devices are tri-mode and quad-mode devices respectively. Tri-mode means support for analogue terrestrial/cable, digital terrestrial and DVB-S digital satellite. Quad-mode devices additionally support DVB-S2 HD digital satellite. The HVR-4000 marks a change in bundled applications in that instead of using Hauppauge's WinTV2000 package, it ships with Cyberlink PowerCinema. Personal Video Recorders The Personal Video Recorder (PVR) range uses an on-board MPEG/MPEG-2 encoder to compress the incoming analogue TV signals. The benefits of using a hardware encoder include lower CPU usage when encoding live TV. The first WinTV-PVR product was the WinTV PVR-PCI, launched in late 2000 and not receiving any driver updates since February 2002. It was joined by the WinTV PVR-USB, which has two variants. The first variant supported MPEG-2 streams up to 6 Mbit/s and supported Half-D1 resolutions (320 × 480). This was replaced by an updated model supporting up to 12 Mbit/s streams and Full-D1 resolution (720 × 480). The first WinTV-PVR to gain popularity was the PVR-250. The original version of the PVR-250 was a variant of the Sag Harbor (PVR-350) which used the ivac15 chipset. Although the chipset was able to do hardware decoding the video out components were not included on the card. In later versions of the PVR-250 the ivac15 was replaced with the ivac16 to reduce cost and to relieve heat issues. The PVR-250 and PVR-350 were joined by the USB 2.0 PVR-USB2 to complete their generation of devices. Their successors, the PVR-150 and PVR-500, were released alongside the PVR-250/350/USB2 and while popular with both OEMs and the general public, there have been numerous driver issues as well as video quality complaints. The PVR-500 was released as a Media Center card and wasn't supplied with Hauppauge's WinTV2000 software. It was effectively two PVR-150s on a single board, connected via a PCI-PCI bridge chip. The PVR-USB2 was silently replaced with the PVR-USB2+ which is identical both visually and terms of features, but uses a Conexant chipset rather than the Philips chipset in the old
