A recording medium has a first recording area on which recording information is recorded, and a second recording area on which management information for managing the recording information is recorded. The second recording area includes a bit rate recording area for recording a bit rate.

Recording medium, and system and method for recording and reproducing the recording medium

An information record apparatus includes: a down-convert device for down-converting a first content information having a first reproduction quality (HD) into a second content information having a second reproduction quality (SD) which is lower quality than the first reproduction quality; a scramble device for generating scramble information by scrambling the first content information, on the basis of a predetermined scramble key; and a first record device for recording the second content information and the scramble information into a first record medium.

Scrambling content information in a first recording medium when downgrading the quality of content information for storage on a second recording medium

An information recording apparatus () is provided with: a recording device () for recording record information into a first or second recording layer by irradiating thereon laser light; a first controlling device () for controlling the recording device to record the record information into a first object area of the second recording layer which faces a recorded area of the first recording layer; and a second controlling device () for controlling the recording device to record the record information into a second object area of the second recording layer which faces an unrecorded area of the first recording layer smaller than a predetermined width, out of an unrecorded area whose both ends are adjacent to the recorded area.

Information recording apparatus and computer program

An information recording medium (), provided with: a first recording layer (Llayer) and a second recording layer (Llayer) in which record information can be recorded; and a plurality of first block areas, each of which includes a recording area () of a first size on the first recording layer and a recording area () on the second recording layer located at a position facing the recording area of the first size on the first recording layer, and each of which is a unit by which the record information is recorded, at least one of the first recording layer and the second recording layer comprising a size area () to record therein first size information () which indicates the first size.

Information recording medium, information recording device and method, and computer program

A broadcast storage unit, which receives a program to be broadcasted digitally and records the program, includes a DeMUX processing unitthat acquires program information concerning a program to be broadcasted, an SI information analyzing unitthat extracts information on a new program from the acquired program information, a recording condition setting unitthat reserves the new program for recording based on the extracted program information, and a storing unitthat records the new program that is reserved for recording.

Apparatus and method which enables fully recording a fragmented program even with an operation after initial few airings

A recording medium has a first recording area on which recording information is recorded as a set of recording units, and a second recording area on which control information for controlling the recording information to be recorded on the first recording area is recorded. Identifying information for identifying a management condition of the recording information recorded on the first recording area is also recorded on the second recording area at every recording unit.

Recording medium and system for recording and reproducing the recording medium

An information editing apparatus for editing a reproduction manner of record information which is recorded on an information storage medium and includes at least one picture information, includes: a selecting unit for selecting a partial record information from the record information, the partial record information being part of the record information and including at least one picture information; a designating unit for designating a reproduction timing of the selected partial record information; an extracting unit for extracting the picture information included in the partial record information as a representative picture information indicative of the partial record information; and a recording unit for recording one of the extracted representative picture information and a designation information indicative of a recorded position on the information storage medium of the representative picture information and the designated reproduction timing on the information storage medium as a reproduction control information separately from the record information.

Information editing apparatus and information reproducing apparatus

A recording medium has a first recording area on which multiplexed audio informations are recorded as sets of one or more information units, a second recording area on which control information for controlling recording of the multiplexed audio informations are recorded. The control informations include first information representing the number of sets of information composing the multiplexed audio informations, and second information instructing to record the multiplexed audio informations as a stream.

Recording medium and system for recording and reproducing the recording medium using control information that represents the number of sets of information composing the multiplexed audio information

A management server device in a contents providing system can communicate with a user terminal through a communication network. The management server device includes a play-list creation device which creates a play list of contents based on user input to the user terminal, a storage device which stores the created play list in relation to a user, and a transmission device which acquires a play list from the storage device according to a request from the user terminal.

Management server device and terminal device for a contents providing system

An apparatus records main information and sub information onto an information recording medium, which has a main recording area and a sub recording area. The apparatus is provided with an receiving device that receives the main information input from the external source; an accumulating device that accumulates the main information received by the receiving device; a recording device that records the main information and the sub information to the main recording area and the sub recording area, respectively; and a controller that determines whether or not an amount of the main information accumulated in the accumulating device is smaller than a predetermined amount, and that controls the recording device.
