Inter-prediction method and video encoding/decoding method using the inter-prediction method

摘要

An inter-prediction method and a video encoding/decoding method using the inter-prediction method are disclosed. The video encoding method using inter-prediction includes: encoding a first picture that serves as a reference for random access; inter-prediction encoding a block included in a second picture, which is displayed before the first picture, by using a plurality of reference pictures; generating reference picture information representing whether a past picture, which is displayed before the second picture, is used as a reference picture for encoding the second picture; and transmitting the encoded first and second pictures and the reference picture information.

主权项

1. A video encoding method using inter-prediction, comprising:
encoding a first picture, wherein the first picture serves as a random access picture and is encoded without referring to a reference picture which has already encoded and then decoded; inter-prediction encoding a block included in a second picture, which is encoded after the first picture and displayed before the first picture, by using a plurality of reference pictures; generating reference picture information representing whether one or more past pictures, which are encoded before the first picture and displayed before the first picture, are used as reference pictures for encoding the second picture; and transmitting the encoded first and second pictures and the reference picture information, wherein, when the one or more past pictures are used as the reference pictures for encoding the second picture, the one or more past pictures are deleted from a memory after encoding at least the second picture.
