Its subsets are Protected Video Path (PVP) and Protected User Mode Audio (PUMA).
In September 2009, AMD announced the ATI Radeon HD 5000 series video cards, which have HDMI 1.3 output (deep color, xvYCC wide gamut capability and high bit rate audio), 8-channel LPCM over HDMI, and an integrated HD audio controller with a Protected Audio Path that allows bitstream output over HDMI for AAC, Dolby AC-3, Dolby TrueHD and DTS-HD ...
Motherboards typically do not have any more than eight built-in output channels (7.1 surround sound) and four input channels (back and front panel microphone inputs, and a back-panel stereo line-in). Users requiring more audio I/Os will typically opt for a sound card or an external audio interface , as these provide additional features that are ...
Windows Sound Recorder no longer saves to wave (.wav) format by default. Instead, it saves as Windows Media Audio (.wma) format. In the Home Basic N and Business N variants of Windows Vista, the wave format is still used by default. [65] Windows 10's Voice Recorder (the modern equivalent to Windows Sound Recorder) only saves to the MPEG-4 (.m4a ...
Video and Audio Capture devices: Devices used to route audio/video streams (eg.

With the exception of the VGA HD A/V Cable cable and HDMI Audio Adapter , all cables are also capable of outputting SD video at 480i /60 Hz ( NTSC or PAL60 , depending ...
Analog prevention distorts the video signal to prevent high quality copying from the output. AnyDVD is also able to remove copy-prevention from audio CDs. The ripper module is based on code from Elby's CloneDVD. Old versions used a ripper based on FixVTS, but FixVTS was shut down by legal threats from Sony in June 2007. [4]
MPEG-2 and MPEG-4 AAC-LC decoders without SBR support will decode the AAC-LC part of the audio, resulting in audio output with only half the sampling frequency, thereby reducing the audio bandwidth. This usually results in the high-end, or treble, portion of the audio signal missing from the audio product.
