摘要
It is provided a processing method for video data that can be displayed on at least one display device. A predetermined quantity of static fields of view (FOV) datasets from the video data are precalculated and stored, video data for the temporal transitions between the stored, static FOV data sets are further calculated and stored as dynamic FOV datasets (transition data), wherein, immediately or at a later point in time, a static or dynamic initial FOV and a static or dynamic target FOV are specifically selected for this purpose, in particular by a user, and the video data corresponding in time to the selected FOV datasets, including the dynamic transition data between the initial FOV and the target FOV can be streamed or are streamed.
說明書
This application is the United States national phase of International Application No. PCT/EP2018/058926 filed Apr. 6, 2018, and claims priority to German Patent Application Nos. 10 2017 110 506.9 filed May 15, 2017, and 10 2017 125 544.3 filed Nov. 1, 2017, the disclosures of which are hereby incorporated by reference in their entirety.
Fundamentally speaking, two approaches exist for seamless transitions between perspectives (fields of view, (FOV)) in videos, which make a repeated recalculation (i.e. a calculation in real time) necessary.
The forms of embodiment proposed here propose a further approach in which the calculation in real time is omitted in that the corresponding video data are precalculated and reused.
A perspective change is the change in the field of view, in particular in 360°/panorama videos, or between partial regions in an altogether larger image region of a plane video, or an alternative sequence of a plurality of videos with the same start point.

The invention claimed is:1. A processing method for video data that can be displayed on at least one display device, comprising the following steps:a) a predetermined quantity of static fields of view (FOV) datasets from the video data are precalculated on a server and stored on a content distribution network (CDN), b) video data for the temporal transitions between the stored, static FOV data sets are further calculated on the server and stored on the CDN as dynamic FOV datasets (transition data), wherein, immediately or at a later point in time, c) a static or dynamic initial FOV and a static or dynamic target FOV are specifically selected for this purpose, in particular by a user, and d) the video data corresponding in time to the selected FOV datasets, including the dynamic transition data between the initial FOV and the target FOV can be streamed or are streamed from the CDN to the at least one display device. 2. The processing method as claimed in claim 1 , wherein the video data, including the dynamic transition data, can be displayed or are displayed on the display device, in particular a client. 3. The processing method for video data as claimed in claim 1 , wherein only the video data corresponding in time to the initial FOV dataset, the target FOV dataset and the dynamic transition data can be streamed or are streamed. 4. The processing method for video data as claimed in claim 1 , wherein the precalculated static FOV datasets and the precalculated dynamic transition data sets are stored on a server system, in particular a distributed server system. 5. The processing method for video data as claimed in claim 4 , wherein the server system is constructed in a geographically distributed form, and the datasets are at least partially redundantly stored thereon. 6. The processing method for video data as claimed in claim 1 , wherein the dynamic transition data can be selected from a dataset that covers a predetermined region, in particular an angular region or solid angular region. 7. The processing method for video data as claimed in claim 1 , wherein the position, in particular the standpoint and/or the direction of view of a virtual observer in the initial FOV and the target FOV, is different. 8. The processing method for video data as claimed in claim 1 , wherein the display device comprises at least a flat screen, at least a curved panoramic screen, a hemispherical projection surface, a head-mounted display and/or a fulldome projection surface. 9. A client device configured and designed for use in the processing method as claimed in claim 1 , in particular with a means for the targeted selection of an initial FOV and a target FOV. 10. A processing system for video data that can be displayed on at least one display device, comprisinga server means for precalculating and storing a predetermined quantity of static FOV datasets from the video data on a content distribution network (CDN), the server means for further calculating and storing on the CDN dynamic FOV datasets as transition data for the temporal transitions of the stored static FOVs, means for the targeted selection of a static or dynamic initial FOV and a static or dynamic target FOV, in particular by a button that can be pressed by a user, in the at least one display device, and means for streaming the video data between the server means and the at least one display device corresponding in time to the selected FOV data sets, including the dynamic transition data between the initial FOV and the target FOV. 11. The processing system as claimed in claim 10 , further comprising a display device, in particular in a client. 12. The processing system as claimed in claim 10 , wherein at least one ofthe means for precalculating and storing a predetermined quantity of static FOV datasets from the video data, the means for calculating and storing dynamic FOV datasets as transition data for the temporal transitions of the stored static FOVs, the means for the targeted selection of a static or dynamic initial FOV and a static or dynamic target FOV, in particular by a button that can be pressed by a user, and the means for streaming the video data corresponding to the selected FOV data sets, including the dynamic transition data between the initial FOV and the target FOV, are disposed in a manner distributed over different computers.
