Abstract
Abstract A method for reproducing multimedia data in response to plural requests for reproduction using an optical disk library unit having at least one optical disk drive. When a new request for reproduction of multimedia data is given to the optical disk library unit during reproduction of multimedia data recorded over plural optical disks, the new request for reproduction is refused if an optical disk having the multimedia data requested by the new request is the same of one of the plural optical disks having the multimedia data being reproduced.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
A method for reproducing multimedia data in response to plural requests for reproduction using an optical disk library unit having at least one optical disk drive, wherein, when a new request for reproduction of multimedia data is given to the optical disk library unit during reproduction of multimedia data recorded over plural optical disks, this new request for reproduction is refused if an optical disk having the multimedia data requested by the new request is the same as one of the plural optical disks having the multimedia data being reproduced.
Claim 2
Independent Claim
90 words
A method for reproducing multimedia data in response to plural requests for reproduction using an optical disk library unit having at least one optical disk drive, wherein, when a new request for reproduction of multimedia data is given to the optical disk library unit during reproduction of multimedia data recorded over plural optical disks, this new request for reproduction is refused if an optical disk having the multimedia data requested by the new request is the same as one of the plural optical disks having the multimedia data being reproduced.
Claim 3
Independent Claim
140 words
A method for reproducing multimedia data in response to plural requests for reproduction using an optical disk library unit having at least one optical disk drive, the method comprising steps of: storing an upper limit of the number of multimedia data reproducible simultaneously from a single optical disk; storing a reproduction number for each optical disk contained in the optical disk library unit, which reproduction number is the sum of the number of multimedia data being reproduced from the optical disk and the number of multimedia data to be reproduced later from the optical disk; and when a request for reproduction of multimedia data is given to the optical disk library unit, refusing this request if the number obtained by adding 1 to the reproduction number of the optical disk having the requested multimedia data exceeds the upper limit number.
Claim 4
Independent Claim
140 words
A method for reproducing multimedia data in response to plural requests for reproduction using an optical disk library unit having at least one optical disk drive, the method comprising steps of: storing an upper limit of the number of multimedia data reproducible simultaneously from a single optical disk; storing a reproduction number for each optical disk contained in the optical disk library unit, which reproduction number is the sum of the number of multimedia data being reproduced from the optical disk and the number of multimedia data to be reproduced later from the optical disk; and when a request for reproduction of multimedia data is given to the optical disk library unit, refusing this request if the number obtained by adding 1 to the reproduction number of the optical disk having the requested multimedia data exceeds the upper limit number.
Claim 5
Dependent Claim
172 words
A multimedia server system comprising an optical disk library unit wherein multimedia data recorded in plural optical disks are processed with at least one optical disk drive, and a server for distributing the multimedia data recorded in the optical disks to plural clients, said system comprising: a recording media storage means for storing, for each multimedia data, an identification data that identifies an optical disk in which the multimedia data is recorded; an identification data comparing means for comparing the identification data of the plural optical disks with each other and outputting a result; and a control means for accepting a request for reproduction of multimedia data from the client if the result of the comparison by the identification data comparing means indicates that the identification data of the plural optical disks is different and for refusing a request for reproduction of multimedia data from the client if the result of the comparison by the identification data comparing means indicates that the identification data of the plural optical disks is the same.
Claim 6
Dependent Claim
172 words
A multimedia server system comprising an optical disk library unit wherein multimedia data recorded in plural optical disks are processed with at least one optical disk drive, and a server for distributing the multimedia data recorded in the optical disks to plural clients, said system comprising: a recording media storage means for storing, for each multimedia data, an identification data that identifies an optical disk in which the multimedia data is recorded; an identification data comparing means for comparing the identification data of the plural optical disks with each other and outputting a result; and a control means for accepting a request for reproduction of multimedia data from the client if the result of the comparison by the identification data comparing means indicates that the identification data of the plural optical disks is different and for refusing a request for reproduction of multimedia data from the client if the result of the comparison by the identification data comparing means indicates that the identification data of the plural optical disks is the same.
Claim 7
Dependent Claim
191 words
A multimedia server system comprising an optical disk library unit wherein multimedia data recorded in plural optical disks are processed with at least one optical disk drive, and a server for distributing the multimedia data recorded in the optical disks to plural clients, said system comprising: a reproducible data number storage means for storing an upper limit of the number of multimedia data reproducible simultaneously from each optical disk; a reproduction number storage means for storing a reproduction number of each optical disk, which reproduction number is the sum of the number of multimedia data being reproduced from the optical disk and the number of multimedia data to be reproduced later from the optical disk; and a control means for accepting a request for reproduction of multimedia data from the client if the contents of the reproducible data number storage means is greater than or equal to the reproduction number stored in the reproduction storage means and for refusing a request for reproduction of the multimedia data from the client if the contests the reproducible data number storage means is less than the reproduction number stored in the reproduction storage means.
Claim 8
Dependent Claim
191 words
A multimedia server system comprising an optical disk library unit wherein multimedia data recorded in plural optical disks are processed with at least one optical disk drive, and a server for distributing the multimedia data recorded in the optical disks to plural clients, said system comprising: a reproducible data number storage means for storing an upper limit of the number of multimedia data reproducible simultaneously from each optical disk; a reproduction number storage means for storing a reproduction number of each optical disk, which reproduction number is the sum of the number of multimedia data being reproduced from the optical disk and the number of multimedia data to be reproduced later from the optical disk; and a control means for accepting a request for reproduction of multimedia data from the client if the contents of the reproducible data number storage means is greater than or equal to the reproduction number stored in the reproduction storage means and for refusing a request for reproduction of the multimedia data from the client if the contests the reproducible data number storage means is less than the reproduction number stored in the reproduction storage means.
