Problems solved by technology

Since 2003, however, due to improvements in network architectures for delivering encoded video, as well as advances in prediction mechanisms, the concealment of missing fragments has become less and less efficient, making the attractiveness of independent decodability of fragments significantly reduced. piece

Embodiment Construction

[0023] figure 1 A simplified block diagram of a communication system (100) of an embodiment of the disclosure is shown. The system (100) may include at least two terminals (110-120) interconnected by a network (150). For one-way data transmission, a first terminal (110) may encode video data at a local location for transmission to another terminal (120) over a network (150). The second terminal (120) may receive encoded video data of another terminal from the network (150), decode the encoded data and display the restored video data. One-way data transfer is often used in media service applications, etc.

Abstract

A method and device for decoding video streams. The video stream includes at least two encoded video sequences. The sequence parameter set used by each of the at least two coded video sequences differs from the sequence parameter set used by other coded video sequences by at least one value. Each of the at least two encoded video sequences includes at least two encoded images. The method includes,before decoding any one of the encoded images of the at least two encoded video sequences, the decoder decoding and enabling a single set of decoder parameters related to the at least two encoded video sequences. The method also includes the decoder decoding at least one encoded image of the at least two encoded video sequences.

Description

[0001] Related documents [0002] This application claims priority to U.S. Provisional Application No. 62 / 730,885, filed September 13, 2018, and U.S. Application No. 16 / 232,675, filed December 26, 2018, the disclosures of which are incorporated herein by reference in their entirety. technical field [0003] The methods and devices in various embodiments relate to video encoding and decoding, and in particular, relate to methods and devices for encoding and decoding using a high-level syntax framework. Encoding priority and persistence of high-level syntax parameters in parameter sets, such as sequence and image parameter sets, and some high-level headers, such as image headers, is also disclosed. Background technique [0004] Video encoding and decoding using inter-picture prediction with motion compensation has been applied. Uncompressed digital video may consist of a sequence of images, each with a certain spatial dimension, such as 1920×10×0 luma samples and correlated c...
