Provided is an image transmission method. Left-eye image data and right-eye image data corresponding to a same original image frame in a target video are divided into sub-images on the image processing device side, multiple sets of image data in one-to-one correspondence with the sub-images are generated, and transmitted to the image display device through transmission threads. Each of the multiple sets of image data includes a sub-image, and first and second sequence numbers that correspond to the sub-image. Left-eye image data and right-eye image data corresponding to a same original image frame are obtained by combining sub-images in the multiple sets of image data, by the image display device, based on first and second sequence numbers in the multiple sets of image data. Finally, a left-eye image corresponding to the left-eye image data and a right-eye image corresponding to the right-eye image data are played.

There are disclosed various methods, apparatuses and computer program products for viewing volume signalling of volumetric video. In accordance with an embodiment of a method information of a viewing volume appropriate for viewing a volumetric video is obtained. The viewing volume is examined to determine what geometrical shapes describe the viewing volume. One or more geometrical shapes determined for describing the viewing volume are selected, wherein signalling information for the selected one or more geometrical shapes is constructed.

A video transmission method that includes predicting, from a texture picture or a depth picture of an anchor viewing position, a picture for a target viewing position on the basis of target viewing position information and processing a prediction error with respect to the predicted picture on the basis of a source picture of the target viewing position. An error-prone region map is generated on the basis of the predicted picture and the source picture. The video transmission method also includes patch packing the prediction error-processed picture on the basis of the error-prone region map and encoding the packed patch on the basis of the texture picture or the depth picture of the anchor viewing position.
