摘要:
Provided is a method of assessing an image quality of each of a base layer and an enhanced layer using a different scheme to assess a quality of a multi-level video based on assessment results. A multi-level video quality assessing system includes: a bitstream extractor to separate a multi-level video into a base layer bitstream and an enhanced layer bitstream; a base layer quality assessment module to generate quality assessment result information of a base layer image by assessing an image quality of base layer bitstream; an enhanced layer quality assessment module to generate quality assessment result information of an enhanced layer image by assessing an image quality of enhanced layer bitstream; and a final video quality assessment module to assess a quality of experience (QoE) of multi-level video based on quality assessment result information of each of the base layer image and the enhanced layer image.
摘要:
An apparatus and method sequentially parses bitstreams based on a removal of an Emulation Prevention Byte (EPB). The apparatus and method may detect an EPB pattern from among sequentially input bitstreams, may store the bitstreams, may store a processed bitstream where the EPB pattern is removed, among the bitstreams, and may select an output of a register buffer based on an input of a buffer selection flag.
