Abstract: The present invention relates to an image information decoding method. The decoding method includes receiving a bit stream including a Network Abstraction Layer (NAL) unit that includes information related to encoded image, and parsing a NAL unit header of the NAL unit. The NAL unit header may not include 1 bit flag information that represents whether a picture is a non-reference picture or a reference picture in the entire bit stream during encoding.

Abstract: Methods and apparatuses for hiding and extracting data based on a pilot code sequence are provided. A data hiding method may include converting an input audio signal to a frequency domain, distorting phase information of the audio signal converted to the frequency domain based on a pilot code sequence representing data to be hidden, and converting the audio signal with the distorted phase information to a time domain and transmitting the audio signal converted to the time domain. The pilot code sequence may be a set of phase values corresponding to a bit value “0” or “1” of data.

Abstract: A method and apparatus for performing an assay process, featuring providing microbeads in a solution, each microbead having a particle substrate with a grating with a superposition of different predetermined regular periodic variations of the index of refraction disposed in the particle along a grating axis and indicative of a code; placing the microbeads on an alignment substrate; reading codes of the microbeads and the position thereof on the alignment substrate; reading the fluorescence on each microbead and the position order thereof on the alignment substrate; and determining an assay result based on bead position order and bead code of the earlier reading steps.
