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 power supply is 1.66amps.The Hauppauge HD-PVR is the first consumer-level analog HD capture device available. Step 2: Plug the power supply into HD PVR 2 After your PC has booted to Windows, plug the supplied Power Supply into the Power input on HD PVR 2. Installing the HD PVR 2 Step 1: Boot into Windows on your PC HD PVR 2 works with laptops or desktop PCs with Windows 8, 7, Vista and Windows XP.
ShowBiz is used to record videos, trim your videos or upload your video recordings to YouTube. HD PVR 2 comes bundled with ArcSoft’s ShowBiz. TS and M2TS: these are native H.264 formats which can be recorded as a Blu-ray disc. MP4 recordings are used by many video editors such as Sony Vegas.
There are three types of HD PVR 2 record formats: MP4: this is an H.264 format which can be played on an XBox360. The recording for- mat used by HD PVR 2 is H.264 with AAC audio. Audio can be supplied to the HD PVR 2 from stereo audio or via the HDMI port. The PS3 does not allow recording from the HDMI port. N ote: if you are recording from a PS3, you must use the Component Video port on the PS3.
