High Quality Content by WIKIPEDIA articles! VDPAU (Video Decode and Presentation API for Unix) is an open source library (libvdpau) and API originally designed by NVIDIA for its GeForce 8 series and later GPU hardware, targeted at the X Window System on Unix-based operating systems (including Linux, FreeBSD, and Solaris). This VDPAU API allows video programs to offload portions of the video decoding process and video post-processing to the GPU video-hardware. Currently, the portions capable of being offloaded by VDPAU onto the GPU are motion compensation (mo comp), inverse discrete cosine transform (iDCT), VLD (Variable-Length Decoding) and Deblocking for MPEG-1, MPEG-2, MPEG-4 ASP (MPEG-4 Part 2), H.264/MPEG-4 AVC and VC-1, WMV3/WMV9...

High Quality Content by WIKIPEDIA articles! X-Video Bitstream Acceleration (XvBA), designed by AMD for its ATI Radeon GPU, is a future extension of the X video extension (Xv) for the X Window System on Linux operating-systems. XvBA API allows video programs to offload portions of the video decoding process to the GPU video-hardware. Currently, the portions designed to be offloaded by XvBA onto the GPU are motion compensation (mo comp) and inverse discrete cosine transform (iDCT), and VLD (Variable-Length Decoding) for MPEG-2, MPEG-4 AVC (H.264) and VC-1 encoded video. XvBA is a Linux equivalent of Microsoft's DirectX Video Acceleration (DxVA) API for Windows and a competitor to NVIDIA's Video Decode and Presentation API for Unix (VDPAU)....

High Quality Content by WIKIPEDIA articles! X-Video Motion Compensation (XvMC), is an extension of the X video extension (Xv) for the X Window System. The XvMC API allows video programs to offload portions of the video decoding process to the GPU video-hardware. In theory this process should also reduce bus bandwidth requirements. Currently, the supported portions to be offloaded by XvMC onto the GPU are motion compensation (mo comp) and inverse discrete cosine transform (iDCT) for MPEG-2 video. XvMC also supports offloading decoding of mo comp, iDCT, and VLD ("Variable-Length Decoding", more commonly known as "slice level acceleration") for not only MPEG-2 but also MPEG-4 ASP and MPEG-4 AVC (H.264) video on VIA Unichrome (S3 Graphics...

High Quality Content by WIKIPEDIA articles! X-Video Bitstream Acceleration (XvBA), designed by AMD for its (ATI) Radeon GPU and Fusion APU, is an arbitrary extension of the X video extension (Xv) for the X Window System on Linux operating-systems. XvBA API allows video programs to offload portions of the video decoding process to the GPU video-hardware. Currently, the portions designed to be offloaded by XvBA onto the GPU are motion compensation (MC) and inverse discrete cosine transform (IDCT), and variable-length decoding (VLD) for MPEG-2, MPEG-4 AVC (H.264) and VC-1 encoded video.

Over the last decade, a wide spectrum of multimedia resource formats has become available to an increasing number of users who desire to access it through various devices and over heterogeneous networks. This book describes means for device and coding format independent access to advanced multimedia resources in an interoperable way. That is, it addresses issues as indicated in the scenario above which are generally referred to as Universal Multimedia Access (UMA). In particular, it proposes a generic XML-based multimedia publishing framework which allows the adaptation of advanced multimedia resources in a coding format independent way. XML is used to describe the high-level structure of the multimedia resources which enables the...
