Title:
ENCODING METHOD, DECODING METHOD, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/169426
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are an encoding method, a decoding method, and an electronic device. The encoding method comprises: first, acquiring the current frame; then, acquiring, from an external reference list of an encoder, a reconstructed picture corresponding to a reference frame of the current frame, wherein the reference frame of the current frame is a frame which has been encoded by the encoder, and the external reference list is independent of the encoder; then, performing intra-frame encoding on the reconstructed picture by the encoder; and on the basis of an intra-frame encoding result, performing inter-frame encoding on the current frame by the encoder, so as to obtain a code stream corresponding to the current frame. In this way, the encoder can flexibly select a reference frame from the external reference list to perform encoding, such that cross-frame reference or cross-resolution reference can be realized, thereby improving the flexibility of managing the reference frame of the encoder. Therefore, the weak-network resistance of the encoder can be improved, such that when a network condition in an RTC scenario becomes poor, the fluency of a video can be ensured.
