Abstract: A method, apparatus and computer readable medium storing a corresponding computer program for decoding a video bitstream based on multiple decoder cores are disclosed. In one embodiment of the present invention, the method arranges multiple decoder cores to decode one or more frames from a video bitstream using mixed level parallel decoding. The multiple decoder cores are arranged into groups of multiple decoder cores for parallel decoding one or more frames by using one group of multiple decoder cores for said one or more frames, wherein each group of multiple decoder cores comprises one or more decoder cores. The number of frames to be decoded in the mixed level parallel decoding or which frames to be decoded in the mixed level parallel decoding is adaptively determined.

Abstract: A method and apparatus of sharing an on-chip buffer or cache memory for a video coding system using coding modes including Inter prediction mode or Intra Block Copy (IntraBC) mode are disclosed. At least partial pre-deblocking reconstructed video data of a current picture is stored in an on-chip buffer or cache memory. If the current block is coded using IntraBC mode, the pre-deblocking reconstructed video data of the current picture stored in the on-chip buffer or cache memory are used to derive IntraBC prediction for the current block. In some embodiments, if the current block is coded using Inter prediction mode, Inter reference video data from the previous picture stored in the on-chip buffer or cache memory are used to derive Inter prediction for the current block. In another embodiment, the motion compensation/motion estimation unit is shared by the two modes.

Abstract: Methods and apparatuses pertaining to a simulated transparent device may involve capturing a first image of a surrounding of the display with a first camera, as well as capturing a second image of the user with a second camera. The methods and apparatuses may further involve constructing a see-through window of the first image, wherein, when presented on the display, the see-through window substantially matches the surrounding and creates a visual effect with which at least a portion of the display is substantially transparent to the user. The methods and apparatuses may further involve presenting the see-through window on the display. The constructing of the see-through window may involve computing a set of cropping parameters, a set of deforming parameters, or a combination of both, based on a spatial relationship among the surrounding, the display, and the user.

Abstract: A post processing apparatus includes a super-resolution (SR) filtering circuit and a loop restoration (LR) filtering circuit. The SR filtering circuit applies SR filtering to a processing result of a preceding circuit. The LR filtering circuit applies LR filtering to a processing result of the SR filtering circuit. Before the SR filtering circuit finishes SR filtering of all pixels of a frame that are generated by the preceding circuit, the LR filtering circuit starts LR filtering of pixels that are derived from applying SR filtering to pixels included in the frame.
