![]() The 1414 Colossus is a PCI-based encoder card. If the prices of the 12 are the same buy the 1212, but if the 1445 is cheaper then buy it and get the component and IR cables separately. The light that signals recording status is a different color.The Windows software it comes with is different.Does not come with an IR blaster output cable (it still has an IR sensor) one can be purchased from Hauppauge for $7.Comes with cables for connecting a PlayStation 3 or Xbox 360 instead of component cables for a cable or satellite settop box.After the company discovered that many who purchased the HD-PVR did so not for recording high-definition television but to capture their video game play to upload to YouTube, it introduced the 1445 HD-PVR Gaming Edition, with the following minor differences: Hauppauge sells several h.264 high-definition encoders. 11.1 Compile LIRC Modules for IR Transmitter Support.9.3 Adjusting Picture Settings Automatically.9.1 Firmware 0x16+ Picture Control Defaults.6 Hardware Stability and Troubleshooting.2.2 Steps to Add the HD-PVR as a Capture Device in MythTV (0.22 or later).To enable this functionality, be sure to set the audio input to S/PDIF by editing the capture card definition in mythtv-setup and setting the preferred input device to S/PDIF. In all HD-PVR firmwares later than 1.0.3.53, AC-3 multiplexing via S/PDIF is available, allowing one to multiplex the original 5.1 channel audio track into the captured stream. HD-PVR users are encouraged to contribute to the page to ascertain real-world playback requirements without VDPAU or some other form of hardware-accelerated playback with MythTV. HD Playback Reports acts as a repository for processor requirements to play high definition material. ![]() Hauppauge recommends a dual-core CPU as a minimum if not using VDPAU a frequently cited minimum for medium-bitrate H.264 playback is a Core 2 Duo 1.8 Ghz processor. ![]() By contrast, even systems which easily play back US broadcast/cable MPEG-2 HD are likely to fail altogether when playing back a recording from the HD-PVR without hardware acceleration. Fortunately, using VDPAU or VDA video card hardware acceleration makes H.264 playback easy. The tradeoff is that decoding H.264 material is very processor-intensive. The HD-PVR uses modern codecs capable of exceptional compression rates at excellent quality. A 13.5 Mb/s H.264 stream is roughly equivalent to a full-channel-bitrate MPEG-2 recording at approximately 19 Mb/s. The H.264 video codec is, bit-for-bit, up to 40% more efficient than the MPEG-2 video codec commonly used in US HDTV broadcasts today. Capture resolution is dependent on the source (ie 720p video will be captured as 720p, 1080i as 1080i, etc.) but the bitrate is user-selectable from 1 megabit/second up to 13.5 megabits/second. The streams are multiplexed into a slightly modified MPEG-2 Transport Stream container. The HD PVR captures at resolutions from VGA/D1 (480i) up to 1080i, and encodes the component inputs in real time using the H.264/MPEG-4 video codec and the AAC audio codec. Prior to this device, component capture devices were cost-prohibitive and were not directly supportable within Linux. In other words, since component video is not and cannot be encrypted, previously uncapturable HD sources such as satellite and premium television will now be fully accessible in MythTV. The HD-PVR is a highly popular capture device because it captures video via component output, permitting the user to capture high-definition video from most sources and without concern for encryption. ![]() The HD-PVR is a USB device that captures the component video outputs and analog/optical audio outputs of any consumer device (including cable/satellite set-top-boxes, HD disk players, video game consoles, and various other home media devices). The Hauppauge HD-PVR is the first consumer-level analog HD capture device available.
