Abstract: According to one method, at a source side or an encoder side, a selected viewport associated with the 360-degree virtual reality images is determined. One or more parameters related to the selected pyramid projection format are then determined. According to the present invention, one or more syntax elements for said one or more parameters are included in coded data of the 360-degree virtual reality images. The coded data of the 360-degree virtual reality images are provided as output data. At a receiver side or a decoder side, one or more syntax elements for one or more parameters are parsed from the coded data of the 360-degree virtual reality images. A selected pyramid projection format associated with the 360-degree virtual reality images is determined based on information including said one or more parameters. The 360-degree virtual reality images are then recovered according to the selected viewport.
