Abstract

A recording apparatus includes a reception unit and a recording unit. The reception unit receives a broadcast signal, out of a plurality of broadcast signals that can be specified by conditions made up of broadcast frequencies and other items such as reception areas. The recording unit records the broadcast signal received by the reception unit and broadcast ID information that enables the broadcast signal to be identified out of a plurality of broadcast signals, onto a recording medium in an interrelated manner. A playback apparatus includes a reading unit, a display unit and a playback unit. The reading unit reads a program, which is a broadcast signal during a certain period, and at least part of broadcast ID information. The display unit displays at least part of the read broadcast ID information and the playback unit plays back the read program.

Claims

1. A recording apparatus comprising:

reception means for receiving one broadcast signal, out of a plurality of broadcast signals, each broadcast signal being specified using a condition, the condition including a broadcast frequency and at least one other item; and

recording means for recording

(1) the broadcast signal received by the reception means, and

(2) broadcast ID information based on a channel number and other information, the broadcast ID information enabling the received broadcast signal to be identified out of the plurality of broadcast signals,

on a recording medium in an interrelated manner, wherein

the recording medium is a rewritable optical disc,

the recording means records data onto the recording medium in conformity with DVD Video Recording Standard, treats a part of the broadcast signal received by the reception means during a certain period as a program, and records the program and the broadcast ID information on the recording medium,

the broadcast ID information being recorded into an IT_TXT area in a management information file on the optical disc and is linked to a recording area for the recorded program, and

the broadcast ID information being recorded in accordance with a data application format that is shown by a data application ID recorded together with the broadcast ID information, in a text field that is appended with an IDCD value “

0x90”

.

2. A playback apparatus for playing back a program recorded on a recording medium,

the recording medium storing the program and broadcast ID information for the program in an interrelated manner,

the program being a part of a broadcast signal during a certain period,

the broadcast ID information (1) identifying the broadcast signal, out of a plurality of broadcast signals able to be specified by a condition including a broadcast frequency and at least one other item, on which the program was received, and (2) being based on the broadcast frequency and other information,

the playback apparatus comprising:

reading means for reading the program and at least part of the broadcast ID information related to the program;

display means for displaying the at least part of the broadcast ID information read by the reading means; and

playback means for playing back the program read by the reading means, wherein

the broadcast ID information includes broadcast station ID information that (a) identifies a broadcast station that broadcasts the broadcast signal for the program on the recording medium out of a plurality of broadcast stations that broadcast the plurality of broadcast signals and (b) is specified based on a channel number and the other information,

the reading means reads the broadcast station ID information from the recording medium,

the display means displays the broadcast station ID information read by the reading means,

the recording medium is a rewritable optical disc,

the program aid management information, including an IT_-TXT area that is linked to an area in which the program is recorded on the optical disc, are recorded in conformity with DVD Video Recording Standard,

the broadcast ID information of the program is recorded in an IT_TXT area in accordance with a data application format that is shown by a data application ID recorded together with the broadcast ID information, in a text field that is appended with an IDCD value “

0x90”

,

the reading means judges whether the data application ID paired with the broadcast ID information, including the broadcast station ID information, matches a predetermined value, and reads the broadcast station ID information only when the data application ID matches the predetermined value,

the management information includes a LAST_MNF_ID area, and

the reading means judges whether a predetermined value is stored at a predetermined position in the LAST_MNF_ID area and suppresses reading of the broadcast station ID information when the predetermined value is not stored.

3. A recording apparatus comprising:

reception means for receiving a broadcast signal;

program recording means for recording a program which is a part of the broadcast signal received by the reception means during a certain period, on a recording medium; and

program attribute recording means for recording program-related information, which is linked to an area in which the program is recorded, with a data construction that is defined by a predetermined standard, and recording attribute information, which shows attributes of the program and is not defined by the predetermined standard, in the program-related information with a data construction that conforms with an application format, the application format being shown by a data application ID that the program attribute recording means records as a pair with the attribute information,

wherein the program attribute recording means records the data application ID in a last recording apparatus information area, the predetermined standard dictating that a recording apparatus that records data also records apparatus information in the last recording apparatus information area.

4. A playback apparatus for playing back a program that is recorded on a recording medium,

the recording medium storing

(1) a program

(2) program-related information, which

(a) is linked to an area in which the program is recorded,

(b) has a data construction that is defined by a predetermined standard, and

(c) includes attribute information, which shows attributes of the program and is not defined by the predetermined standard,

the attribute information having a data construction that conforms with an application format, and

the application format being shown by a data application ID that is recorded as a pair with the attribute information,

the playback apparatus comprising:

reading means for reading the program and the attribute information;

display means for displaying the attribute information read by the reading means; and

playback means for playing back the program read by the reading means, wherein

the recording medium includes a last recording apparatus information area into which a recording apparatus that records data must, according to the predetermined standard, also record apparatus information, and

the reading means judges whether the data application ID is recorded in the last recording apparatus information area, and only reads the attribute information on judging that the data application ID is recorded.
