BEST MODE FOR CARRYING OUT THE INVENTION In this specification, "format conversion" means to reduce the amount of information to such an extent that a user can view. For example, format conversion includes conversion from HD format to SD format, conversion from a format including video data and audio data to a format including only audio data, and conversion of video data of 30 fields / second to video data of 10 fields / second. Including conversion.

The information converted by the "format conversion" includes header information. The header information includes information indicating a format of information including the header information. In “format conversion”, information indicating a format included in the header information is also converted.

In the conventional D-VHS or the like, the broadcast data is stored as it is (all the information of the trapon) (recording).
I do. In the case of this method, since a very large storage area is required, the possibility that the viewer can store everything he wants to store is reduced.

For this purpose, in the present invention, the storage format can be designated for each program (for each recording unit).
For example, when recording news broadcast only in high-definition, it may not be particularly necessary to record in high-definition. In this case, if the data is received in high definition and recorded in SD, the storage capacity required for recording is small. In the case of a music program, even if video data is thinned out and only audio data is stored, it is possible to satisfy a viewer's request. By doing so, more programs can be stored in the viewer with the same storage capacity than before.

The timing at which the format is converted is controlled by the storage control unit. There are two methods. The first is real-time conversion (real ti
meconvert). That is, it is a procedure for receiving, converting, and storing.

The other is a procedure for saving data as it is once received in the primary storage area and converting the data when the CPU power has sufficient time, because data may be lost if the CPU power is very high for the conversion. It is.

Regarding the reproduction, the storage control unit assumes that the user views the recorded data as it is, and also converts the format of the recorded data and reproduces the data. In addition, in addition to the method of always specifying the format for each program, the storage specifying unit determines, for example, a default recording format and specifies only when the recording format is different from the default, and the EIT, PMT component_de
A method of automatically controlling based on the information written in the component_tag of the descriptor, the content of the content_descriptor of the EIT
A method of checking a genre based on t_nibble and controlling based on the information, n in the ERT program INDEX
Control by mode_id may be considered. CS,
In the case of CATV, since the genre can be determined by the channel, the channel can be specified.

The method of designation includes a time when a program is scheduled to be recorded and a time when a default setting is made for the storage device. Also, in the case where the storage capacity is likely to overflow in the specified format as in the case of the current video deck, it is also possible to specify the format to be converted. At this time, items that should never be changed can be specified.

The conversion program may be distributed by broadcasting, distributed by media, or distributed by another network. Even when the data is stored in the external storage device, it is possible to specify which format can be copied as long as the format can be converted from the storage format.

If a list of the genres of the broadcast program is required, the EIT or the like flowing in advance is searched.
Also, a function of creating a list on the receiving device is required.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 27 is an explanatory diagram of a storage format determination table 1500 according to Embodiment 6. FIG. 16 is an explanatory diagram of the storage format determination table 1600 according to the sixth embodiment.

The storage format determination section 111 determines a format for storing the program 122 based on the storage format determination table and the capacity calculated by the capacity calculation section 110.

Referring to FIG. 14, a case where the storage format determination table 1400 is used will be described. In the storage format determination table 1400, each storage format is given a priority. The priorities are in the order of HD format, SD format, and audio only format. For example, the capacity required for storage in the HD format is 10 GB, the capacity required for storage in the SD format is 3 GB, and the capacity required for storage in the audio-only format is 100 KB.

For example, when the capacity calculated by the capacity calculation unit 110 is 10 GB or more, the storage format determination unit 111 selects an HD format whose storage capacity is 10 GB as a format for storing the program 122. When the capacity calculated by the capacity calculation unit 110 is less than 10 GB and equal to or more than 3 GB, the storage format determination unit 111 selects an SD format whose storage capacity is 3 GB as a format for storing the program 122. The capacity calculated by the capacity calculation unit 110 is less than 3 GB 10
If it is 0 KB or more, the storage format determination unit 1
Reference numeral 11 denotes a format for storing only the audio whose capacity required for storage is 100 KB as a format for storing the program 122. The capacity calculated by the capacity calculation unit 110 is 100
If it is less than KB, the storage format determination unit 11
No. 1 does not select a storage format and outputs an error message indicating that the program 122 cannot be stored.

As described above, the storage format determining unit 111
Determines a format for storing the program 122 using the capacity calculated by the capacity calculation unit 110 as a parameter. Although the example in which the storage format is determined based on the free space before storing the program 122 is shown, the present invention is not limited to this. The storage format may be determined based on the free space after storing the program 122.

The program information 121 may include information indicating a genre to which the program 122 belongs. The storage format determination unit 111 compares the capacity calculated by the capacity calculation unit 110 with the program 122.
May be determined based on the genre to which the program 122 belongs. For example, a music program is shown in FIG.
5, it can be stored in the SD video + audio format or the audio only format thinned out to 1/3 as described later. The movie program may be stored only in one of the HD format and the SD format, that is, in a format including video, as described later with reference to FIG.

Referring to FIG. 15, a case where the storage format determination table 1500 is used will be described. In the storage format determination table 1500, each storage format is given a priority. Priority is HD format, SD format, SD video thinned to 1/3 +
The audio format is followed by the audio only format. For example, the capacity required for storing in the HD format is 10 GB, the capacity required for storing in the SD format is 3 GB, and S is thinned to 1/3.
The capacity required for storage in the D video + audio format is 1 GB, and the capacity required for storage in the audio only format is 100 KB.

For example, when the capacity calculated by the capacity calculation unit 110 is 10 GB or more, the storage format determination unit 111 selects the HD format whose storage capacity is 10 GB as the format for storing the program 122. When the capacity calculated by the capacity calculation unit 110 is less than 10 GB and equal to or more than 3 GB, the storage format determination unit 111 selects an SD format whose storage capacity is 3 GB as a format for storing the program 122. The capacity calculated by the capacity calculation unit 110 is less than 3 GB and 1 G
B or more, the storage format determination unit 111
Selects the SD video + audio format in which the capacity required for storage is thinned out to 1/3 of 1 GB as the format for storing the program 122. If the capacity calculated by the capacity calculation unit 110 is less than 1 GB and 100 KB or more,
The storage format determination unit 111 selects a format of only audio having a capacity required for storage of 100 KB as a format for storing the program 122. Capacity calculator 11
If the capacity calculated at 0 is less than 100 KB, the storage format determination unit 111 does not select a storage format and outputs an error message indicating that the program 122 cannot be stored.

As described above, the storage format determining unit 111
Determines a format for storing the program 122 using the capacity calculated by the capacity calculation unit 110 as a parameter.

Referring to FIG. 16, a case where the storage format determination table 1600 is used will be described. As described above, for example, the storage format determination table 1600
For example, it can be used to store movie programs. The storage format determination table 1600 has either the HD format or the SD format, that is, only the format including video. The priorities in the storage format determination table 1600 are in the order of HD format and SD format. For example, the capacity required for storing in the HD format is 10 GB, and the capacity required for storing in the SD format is 3 GB.

For example, when the capacity calculated by the capacity calculation unit 110 is 10 GB or more, the storage format determination unit 111 selects the HD format whose storage capacity is 10 GB as the format for storing the program 122. When the capacity calculated by the capacity calculation unit 110 is less than 10 GB and equal to or more than 3 GB, the storage format determination unit 111 selects an SD format whose storage capacity is 3 GB as a format for storing the program 122. If the capacity calculated by the capacity calculation unit 110 is less than 3 GB, the storage format determination unit 111 does not select a storage format and outputs an error message indicating that the program 122 cannot be stored.

The format converter 102 converts the format of the program 122 received by the receiver 101 according to the format determined by the storage format determiner 111 (S1304). The program storage unit 104 stores the program 122 converted by the format conversion unit 102 (S
1305).

If it is determined that program information 121 is not received (NO in S1301),
