Title: METHOD AND SYSTEM FOR ENCODING/DECODING PANORAMIC VIDEO
Abstract:
Provided are a method and system for encoding/decoding panoramic video, said method comprising: a panoramic camera photographing a panoramic video, then sending the panoramic video to a video-data caching unit; according to a viewing-angle division rule, said video-data caching unit dividing the panoramic video into a plurality of viewing-angle video sequences by means of an encoder; encoding each of the viewing-angle video sequences to obtain multiple sets of encoded data; a user equipment decoding said encoded data by means of a decoder and playing the obtained viewing-angle video sequences; the system comprises a panoramic camera, a communications unit, and a user equipment; the solution provided not only accurately determines the trend of a user’s movement, but also ensures, according to a preprocessing unit, real-time decoding of the panoramic video corresponding to the effective field of view (FOV) in front of the viewing angle, reducing the decoding overhead.
