Abstract
Abstract A method for editing audio data includes the steps of creating a header portion containing at least information for indicating a start of an audio unit to be decoded and having composite elements whose values are equal to those of the audio data to which dummy data is to be added, and creating the audio data composed of the dummy data to be ignored during a decoding time. The system for editing audio data is also provided for executing the editing method.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
70 words
A method for editing compressed audio data comprising the steps of: creating a header portion containing at least information for indicating a start of an audio unit to be decoded and having composite elements whose values are equal to those of the compressed audio data to which dummy data is to be added; and creating the audio data composed of the dummy data to be ignored at the decoding time.
Claim 2
Independent Claim
70 words
A method for editing compressed audio data comprising the steps of: creating a header portion containing at least information for indicating a start of an audio unit to be decoded and having composite elements whose values are equal to those of the compressed audio data to which dummy data is to be added; and creating the audio data composed of the dummy data to be ignored at the decoding time.
Claim 3
Dependent Claim
101 words
The editing method as claimed in claim 1 , further comprising the steps of: calculating a regenerating time of the compressed audio data and a regenerating time of compressed video data; deriving the number of minimum audio units from a difference of the regenerating times of said audio data and said video data; and wherein said step of creating the header portion is executed to create the header portion composed of header information extracted from said audio data, and said step of creating the dummy data is executed to create said dummy data corresponding to said number of minimum audio units.
Claim 4
Dependent Claim
56 words
The editing method as claimed in claim 2 , wherein said audio unit is the minimum unit of the audio data corresponding to said original audio data to be decoded, and said dummy data corresponds to the difference of said regenerating time of the compressed audio data and said regenerating time of the compressed video data.
Claim 5
Independent Claim
84 words
A method for editing compressed audio data comprising the steps of: detecting an output of said compressed audio data; and creating a header portion containing at least information for indicating a start of an audio unit to be decoded if the output of said audio data does not contain a predetermined value, said header portion having composite elements whose values are equal to those of said compressed audio data and dummy audio data composed of dummy data to be ignored during a decoding time.
Claim 6
Independent Claim
84 words
A method for editing compressed audio data comprising the steps of: detecting an output of said compressed audio data; and creating a header portion containing at least information for indicating a start of an audio unit to be decoded if the output of said audio data does not contain a predetermined value, said header portion having composite elements whose values are equal to those of said compressed audio data and dummy audio data composed of dummy data to be ignored during a decoding time.
Claim 7
Dependent Claim
44 words
The editing method as claimed in claim 4 , further comprising the steps of: capturing video data through a picture input device; compressing said video data; indicating a start of creating said dummy audio data; and indicating an end of said dummy audio data.
Claim 8
Dependent Claim
36 words
The editing method as claimed in claim 4 , wherein said audio unit is the minimum unit of said audio data corresponding to said inputted audio data to be decoded, and said dummy data is zero.
Claim 9
Independent Claim
62 words
A system for editing audio data comprising: a storage device for storing compressed audio data; and an editing device for obtaining header information by accessing said compressed audio data and creating a header having composite elements whose values are equal to those of said obtained header information and dummy audio data composed of dummy data to be ignored during a decoding time.
Claim 10
Independent Claim
62 words
A system for editing audio data comprising: a storage device for storing compressed audio data; and an editing device for obtaining header information by accessing said compressed audio data and creating a header having composite elements whose values are equal to those of said obtained header information and dummy audio data composed of dummy data to be ignored during a decoding time.
Claim 11
Dependent Claim
66 words
The editing system as claimed in claim 7 , wherein said storage device stores compressed video data, and said editing device calculates the number of minimum audio unit corresponding to a difference of regenerating times between said compressed video data and said compressed audio data and creates the dummy audio data corresponding to the number of the minimum audio units for said difference of regenerating times.
Claim 12
Dependent Claim
110 words
A recording medium to be read by a computer, for storing a program comprising the steps of: calculating regenerating times of compressed audio data and compressed video data; creating the number of minimum audio units corresponding to a difference of said regenerating times between said audio data and said video data; creating a header portion containing at least information for indicating a start of an audio unit to be decoded and having compose elements whose values are equal to those of said audio data; and creating dummy audio data having the number of minimum audio units corresponding to said difference of regenerating times to be ignored during a decoding time.
Claim 13
Dependent Claim
110 words
A recording medium to be read by a computer, for storing a program comprising the steps of: calculating regenerating times of compressed audio data and compressed video data; creating the number of minimum audio units corresponding to a difference of said regenerating times between said audio data and said video data; creating a header portion containing at least information for indicating a start of an audio unit to be decoded and having compose elements whose values are equal to those of said audio data; and creating dummy audio data having the number of minimum audio units corresponding to said difference of regenerating times to be ignored during a decoding time.
