MINIMAL DECODING METHOD FOR SPATIALLY MULTIPLEXING DIGITAL VIDEO PICTURES

摘要

Multiple video picture frames are combined into a spatial multiplex video picture frame that may be fully decoded and displayed. The video display of the spatial multiplex video picture frame is a composite combination of all of the video picture frames that have been combined, and may have an appearance such as a mosaic. Multiplexing the video picture frames involves removing picture headers, creating a picture header for the spatial multiplex video picture frame, and altering the headers of individual components of each video picture frame. The new header for the spatial multiplex video picture frame indicates a slice format frame, and headers of the individual components are altered to provide a slice format based picture position for each video picture frame. The headers of the individual components are altered to become slice based, such as in accordance with the ITU-T H.263 video standard, prior to establishing the slice based picture position if the frames are not already of the slice format.

1. A device, comprising:
a processor; and a memory having instructions storied thereon which, when executed by the processor, cause the processor to perform operations comprising:
removing an image header from each of a plurality of images to be included in a combined image, wherein each image has a plurality of image components, and each image component has an image component header;generating a new image header for the combined image;altering the image component header of each image component to be included in the combined image to set a position for the image component within the combined image; andconcatenating the new image header with the plurality of images having the image header removed and the image components having the altered image component headers to produce the combined image.
