Abstract

DC60 (24/03/47) This invention-based image encoding process includes the encoding procedure (S102, S103) of encoding that considers many images as a single random access unit (RAU), image processor unit. (PPS) that will be used for decoding all images (pic) that are included in the Random Access Unit (RAU) and Sequence Variable Set (SPS), and the Variable Set (S104) substitution procedure (S104). PPS, SPS) that are encoded in the encryption phase (S102, S103) in the random access unit (RAU). Many images are a single random access unit (RAU), an image processor unit (PPS) that will be used for decoding all images (pic) that are included in the random access unit (RAU) and sequence variables ( SPU) and variable set replacement procedure (S104) of variable set representation (PPS, SPS) encoded in the encoding process (S102, S103) in the random access unit (RAU).

Claims (4)

Disclaimer (ALL) which will not appear on the advertisement page: 1. Image encoding process for encoding image signals on a per-image basis. The image to create the code line, has its characteristics, consists of: The encoding process of encoding a set of variables that will be used for decoding all images that Was included in the access unit which was made up of many pictures; And the procedure for replacing a variable set of placing variables encoded in the coding process in each access unit in the code stream. 2. The image encoding process according to claim 1, has a special characteristic: Variables include the set of image variables that will be used for decoding one or more images, and the subsequent image encoding process. Information substitution procedure, variable identifier of placeholder information, variable identifier before code word. For the pixels of the image in the code line, where the variable identifier information that identifies the variable set for The above image 3. The image encoding process, according to claim 2, has a special effect: In the variable replacement process, the variable set is placed before any image in the access unit in the code stream. Encrypt the image according to claim 3, has a special feature: the process of encoding the image comes with it. Information Generation Procedure, Structure Identifier of Generation Information, Identified Structure Identifier The contents of the substitution structure of the set of variables 5. Image encoding process according to claim 2, has a special feature. Variable sets include: large number of image variable sets, and sequence variable sets that are used together. For decoding all images that are included in the access unit, and in the variable set replacement process, the sequence variable is placed on the head side of the access unit in the code line, and the image variable set for the included image. Located in the unit, the sub accesses are placed in the unit Sub-access in the code stream, where the sub-access is obtained by dividing the access unit 6. Image encryption method according to claim 5, has a special feature: the process of encoding such images follows. with Information Generation Procedure, Structure Identifier of Generation Information, Identified Structure Identifier 7. The image encoding process according to claim 6, is unique: In the process of generating structural identifier information, structure identifier information is included in the process of generating structural identifier information. Code data lines and thus were created. 8. Image encryption process according to claim 6, has a unique feature: In the process of generating structural identifier information, structural identifier information is attached. The code line was created. 9. Image encoding process according to claim 2, has a special effect: variable set including many image variables, and in the process of replacing variable sets, image variables. For images placed before such pictures In the access unit in the code line 1 0. The image encoding process according to claim 2, has a special effect: In the process of replacing a variable set, the image variable set for the image is placed before the image as follows. Said in the access unit in the code data line, except for the already placed image variable set 1. 1. The image encoding process according to Clause 9, is characterized by this: in the encryption process, one or all of the image variables are encoded multiple times, and a large number of image variables are encrypted. The same is created, in the process of replacing a set of variables, many of the same image variable sets that are encoded in The encryption procedure is placed in the same access unit 1. 2. The image-encoding process, according to claim 11, has a special effect: a set of variables, including an order variable, that are used together for decoding all images that are Included in the access unit, in the coding process, the sequence variable is encoded multiple times, and a large number of variables. The same encoded sequence is created, and in the substitution process, multiple sets of identical image variables are encoded in The encryption procedure is placed in the same access unit 1. 3. Image encryption process for encoding image signals on the basis of images. The image to create the code line, has its characteristics, consists of: The encoding process of encoding a set of variables that will be used for decoding all images that Is included in the access unit, except for images that refer to images in other access units and are not displayed when random access is made, where the access unit is made up of many images; And the replacement procedure for placing variables encoded in the coding process in each access unit in the code line 1. 4. Image encoding device for encoding image signals based on images. Attach an image to create a line of code, with its characteristics, consisting of: a functional cipher unit to encode the set of variables that will be used for decoding the image. All the images that were included in the access unit were made with many images; And a functional variable-set replacement unit to place the encoded variable set in the input unit. The code in each access unit in the code data line.
