Abstract: A video projection switching apparatus includes a screen interface, a display controller, a switching unit, and a plurality of input interfaces. At least two of the input interfaces are electrically connected to the display controller and used for connecting to external input devices. The screen interface is used for connecting to a display screen. The display controller is electrically connected to the switching unit and the screen interface. When at least two input interfaces both input video signals, the display controller first outputs a video signal input from one of the at least two input interfaces through the screen interface according to a preset program. The switching unit outputs a switching signal to the display controller when a user operates. The display controller selects to output a video signal input from another one of the at least two input interfaces through the screen interface when receiving the switching signal.

Abstract: A method for processing a video data stream, a video decoding apparatus, and a method for encoding data stream are provided. The method includes: receiving a video data stream; generating a layer list using at least the patch-layer association information, the layer list including a first layer associated with the first view, the first layer being based on a first depth of the first view; assigning a first layer identification to the first layer; updating the view list section by adding the first layer as a second view; selecting a first target view for rendering on an output device; selecting one or more patches using at least the layer list and the patch list section; combining the selected one or more patches to form a first intermediate output frame; and performing post processing using at least the view list section.

Abstract: Embodiments of the disclosure provide resolution-based decoding and encoding methods and a bitstream. The method includes the following. A bitstream is parsed to obtain a current patch. Whether the current patch is a patch whose resolution is to be changed is determined. When the current patch is a patch whose resolution is to be changed, the bitstream is parsed to obtain a scaling-rate parameter of the current patch. A scaling factor for the current patch is determined based on the scaling-rate parameter of the current patch. Coordinates of the current patch in a three-dimension (3D) space coordinate system are obtained based on the scaling factor for the current patch.

The decoding method includes: according to a code stream, obtaining spliced map set information and video data to be decoded; performing metadata decoding on the spliced map set information, so as to obtain respective auxiliary information in at least two heterogeneous formats; and performing video decoding on the video data, so as to obtain a spliced image, wherein the spliced image is composed of image sub-blocks corresponding to the at least two heterogeneous formats.

Abstract: Embodiments of the present application provide encoding and decoding methods, an encoder, a decoder, and a storage medium. The decoding method includes: a decoder decodes a code stream, and determines a first indication parameter; when the first indication parameter indicates that a sub-block image unit that does not include geometric information exists, a second indication parameter corresponding to the sub-block image unit is determined; and when the second indication parameter indicates that the sub-block image unit does not include geometric information, reconstruction processing is performed according to texture information corresponding to the sub-block image unit.
