An architecture which allows real-time video editing using a 2D/3D graphics engine. This architecture comprises input and output buffers. It receives video streams from either compressed sources of data or non compressed sources of data. This architecture allows a flexible upgrade of the video effects using software plug ins.

Real-time video editing architecture

Multiple independent displays from one graphics controller can be driven in a wide variety of modes using multiple display controllers. This invention incorporates a unique combination of enhancement building on a generic single multi-display graphics subsystem. Digital video is gaining vast popularity in the worldwide consumer, professional and commercial market. The applications of this invention cover all these market segments and include (but are not limited to) Digital Content Creation, Digital video playback, digital entertainment, DVD Authoring etc etc.

Video display system with two controllers each able to scale and blend RGB and YUV surfaces

Provides an apparatus and method for displaying dual Digital Visual Interface (DVI) displays simultaneously, with independent images, by using a Transition Minimized Differential Signaling (TMDS) serializer with dual channels and one clock. Also provides an apparatus and method allowing either two low-resolution displays or one high-resolution display to be driven by a reduced circuit.

Method and apparatus for real-time video editing using a graphics processor

Multiple stage interleaving through a memory matrix is utilized to separate adjacently disposed bits from bytes of digital information, in a reorganized bit stream. At least two stages of interleaving are required for the preferred embodiments of the invention which achieves a bit separation distance equal to the bit capacity of a plurality of either the matrix columns or rows, with that plurality being the number of adjacently disposed bits in each byte of digital information.
