AI Technical Summary

Problems solved by technology

However, because there are many factors associated with flicker, the adjustment of the quantization step size is very complicated and difficult to achieve
Although conventional techniques reduce flicker to some extent, they do not completely eliminate it

Embodiment Construction

[0014] Hereinafter, embodiments consistent with the present disclosure will be described with reference to the accompanying drawings, which are examples for illustrative purposes only and are not intended to limit the scope of the present disclosure. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0015] figure 1 is a schematic diagram illustrating an exemplary encoding device 100 consistent with the present disclosure. The encoding device 100 is configured to receive video data 102 and encode the video data 102 to generate a bitstream 108, which can be transmitted over a transmission channel.

[0016] In some embodiments, video data 102 may include a plurality of raw (e.g., unprocessed or uncompressed) image frames obtained from any suitable image source (e.g., video recorder, digital camera, infrared camera, etc. )Generated. For example, video data 102 may include a plurality of uncompressed image fr...

Abstract

A method of encoding video data includes inter-coding a block of an image frame to generate an inter-coded block, reconstructing the inter-coded block to generate a reconstructed block, and intra-coding the reconstructed block to generate a double-coded block.

Description

[0001] Copyright notice [0002] Portions of the disclosure of this patent document contain material that is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyrights. technical field [0003] The present disclosure relates to information technology, and more particularly to methods and apparatus for encoding video data. Background technique [0004] Periodic Intra Coding or Periodic Intra Refresh has been widely used in the field of robust video transmission over unreliable channels. Inter-frame flicker (abbreviated as flicker) refers to the discontinuity between an intra-frame (intra-coded frame) and the previous inter-frame (inter-coded frame) that can be perceived, and occurs at low to medium The periodic intra-frame perception of bit-rate encoding is more pron...
