An exemplary decoding method of an input video bitstream including a first bitstream and a second bitstream includes: decoding a first picture in the first bitstream; after a required decoded data derived from decoding the first picture is ready for a first decoding operation of a second picture in the first bitstream, performing the first decoding operation; and after a required decoded data derived from decoding the first picture is ready for a second decoding operation of a picture in the second bitstream, performing the second decoding operation, wherein a time period of decoding the second picture in the first bitstream and a time period of decoding the picture in the second bitstream are overlapped in time.

Decoding method and decoding apparatus for using parallel processing scheme to decode pictures in different bitstreams after required decoded data derived from decoding preceding picture(s) is ready

A graphics processing method for three-dimensional images, applied to a first buffer for storing right-view contents and a second buffer for storing left-view contents, includes the following steps: when a current Vsync status indicates that a display engine is not operating within a right Vsync period of a right-view frame, the drawing engine drawing the right-view contents stored in first buffer; when current Vsync status indicates that the display engine is not operating within a left Vsync period of a left-view frame, the drawing engine drawing the left-view contents stored in second buffer; during the right Vsync period of the right-view frame, the display engine displaying right-view contents stored in first buffer; and during the left Vsync period of the left-view frame, the display engine displaying left-view contents stored in second buffer.

A graphics processing method for three-dimensional images, applied to a first buffer for storing right-view contents and a second buffer for storing left-view contents, includes the following steps: sending drawing commands respectively related to the right-view contents and the left-view contents to a drawing engine; when a current Vsync status indicates that a display engine is not operating within a right Vsync period of a right-view frame, the drawing engine drawing the right-view contents stored in first buffer; when current Vsync status indicates that the display engine is not operating within a left Vsync period of a left-view frame, the drawing engine drawing the left-view contents stored in second buffer; during the right Vsync period of the right-view frame, the display engine displaying right-view contents stored in first buffer; and during the left Vsync period of the left-view frame, the display engine displaying left-view contents stored in second buffer.

An embodiment of the invention provides a method performed by a de-multiplexer that is coupled to a front-end stream buffer and a plurality of back-end video buffers. The front-end stream buffer is configured to buffer a plurality of video data units of a video stream. The video stream includes a plurality of subordinate video streams interleaved therein. Each of the back-end video buffers is configured to buffer the video information contained in a corresponding one of the subordinate video streams. First, the de-multiplexer determines whether it is blocked from fetching the video information of a first video data unit buffered in the front-end stream buffer. Then, if being blocked, the de-multiplexer skips accessing the first video data unit and instead fetches the video information of a second video data unit buffered in the front-end stream buffer.

Electronic devices and methods for processing video streams

A method for performing video display control within a video display system includes: dynamically utilizing two of a plurality of buffers as on-screen buffers for three-dimensional (3D) frames, wherein the plurality of buffers is positioned within the video display system; and during utilizing any of the two of the plurality of buffers as an on-screen buffer, dynamically utilizing at least one other buffer of the plurality of buffers as at least one off-screen buffer for at least one 3D frame. An associated video processing circuit and an associated video display system are also provided. In particular, the video processing circuit is positioned within the video display system, where the video processing circuit operates according to the method.

An apparatus is provided for converting two-dimensional video frames to stereoscopic video frames, comprising a comparing unit, a temporal transform operator and a spatial transform operator. The comparing unit receives a sequence of two-dimensional video frames and provides a comparison result indicative of temporal difference data for the sequence of two-dimensional video frames. The temporal transform operator is coupled to the comparing unit for modifying the sequence of two-dimensional video frames according to the comparison result. The spatial transform operator is coupled to the comparing unit and the temporal transform operator for generating a stereoscopic frame pair according to each frame of the modified video frames. The stereoscopic frame pair comprises a left-eye video frame and a right-eye video frame for providing visual differences perceived by human eyes.
