2. Description of the Related Art FIG. 7 shows a conventional general method of receiving a program.
Broadcast program loaded on the transmitted radio wave from the receiving antenna 2
, And view it using a broadcast receiving terminal 3 such as a TV or a radio. Alternatively, instead of the broadcast receiving terminal, the program is temporarily recorded in a storage device such as a VTR or a cassette tape recorder, and the recorded program is viewed using the broadcast receiving terminal or directly from the storage device.

[0003]

A conventional broadcast program has a viewing method determined at the time of being broadcast, and it is difficult to correct or modify the program after the program is edited. Therefore, as shown in FIG. 8, it is common for the viewer to receive the program broadcasted on the broadcast station side and watch it as it is broadcasted. In order to change or select only a necessary part for viewing, it is recorded in a broadcast storage device such as a VTR or a cassette tape recorder owned by the user and is determined at the time of broadcasting in a broadcast receiving terminal. It is necessary for the viewer to edit the contents of the broadcast, such as fast-forwarding or rewinding the VTR, etc., or to provide two VTRs, cassette tape recorders, etc., dubbing, etc., and re-edit the contents. It was not easy.

[0004]

A broadcast program viewing method and a viewing device according to the present invention include a broadcast storage device that can be randomly accessed in an external device operable within the viewing device or from the viewing device. And additional information (hereinafter referred to as attribute information) relating to the contents of the program.

[0005] With the above features, the viewer of the broadcast program can
In addition to watching the program as determined during the broadcast,
The same broadcast program can be viewed from another viewpoint reflecting the viewer's own preference. For example, you can select and view only the digest of a news program, the viewer can rearrange the order arbitrarily, extract arbitrary parts from multiple programs, reorganize, or use some of the above examples. It can be easily implemented in combination.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an algorithm of a broadcast program viewing method according to the present invention. FIG. 2 shows an example of a configuration of the viewing device of the present invention for implementing the algorithm of FIG. 1, and FIG. 3 shows an example of a method of expressing the attribute information.

In the viewing method according to the present invention, first, a broadcast program is stored in a storage device which can be accessed randomly. At this time, the attribute information is also acquired from outside. The timing of acquiring the attribute information may be before, during, or after the broadcast. Next, what kind of information of the broadcast program stored by the viewer or the like is desired to be obtained as preference information.

Next, the acquired preference information and the attribute information are compared, and the start time and the end time of the program in which the preference information and the program content information in the attribute information match or are similar are stored in a storage device such as a main memory. Keep it. Finally, the stored programs are sequentially reproduced from the stored start time to end time.

FIG. 4 shows an example of a digest program created by using the viewing method according to the present invention. In this digest program, only the program contents that match the viewer's preference are extracted from the state broadcast before editing and reproduced. Such a digest program is effective, for example, in a news program when it is desired to view only news related to a foreign country.

FIG. 5 shows an example of a program in which the order of the program contents is rearranged by using the viewing method according to the present invention. In the program after the rearrangement, rearrangement reflecting the viewer's preferences is performed from the state of being broadcast before editing, and the program contents are reproduced in the order in which the viewer's preferences are reflected. Such a rearranged program is effective, for example, in a news program when it is desired to view fun news first.

FIG. 6 shows an example of a program obtained by partially cutting out and rearranging program contents reflecting a viewer's preference from a plurality of programs using the viewing method according to the present invention. In the program after the cut-out and rearrangement, the program that has been broadcast before the editing is cut out and rearranged by reflecting the viewer's preference, and the program whose content reflects the viewer's preference is reproduced.
Such cut-out and rearranged programs are effective when, for example, a plurality of news programs are accumulated and it is desired to view all sports news among the program contents in a cross-sectional manner.

A viewing apparatus for implementing the algorithm of FIG. 1 will be described with reference to FIG. Broadcast program is T
The data is stored in a hard disk 12 which is a storage device which can be randomly accessed through a V tuner 11. The attribute information is acquired through the modem 13 and temporarily stored in the main memory 14. Thereafter, the extracted character string is input from the viewer using input means such as a keyboard.

Next, the extracted character string is compared with the program content information in the attribute information that has already been acquired, and the matched part is recorded in the main memory 14 as a set of a start time, an end time, and a program. When all the extractions are completed, the corresponding portions from the broadcast programs stored on the hard disk 12 are sequentially transferred to the video output device 16 to display the video.

In the attribute information notation of FIG. 3, [x] is x
Is a non-terminal symbol. (X) indicates that x repeats one or more times. [date],
The hours, minutes, seconds, and milliseconds are 4,
It consists of two, two, two, two, two and three digits right-justified numerical values, and blanks are filled with zeros. [Separator] may be any single character (or symbol). [File end symbol] depends on the operating system of the viewing device.

This viewing apparatus does not need to include all the components in one device, and may be configured by an external directly operable device. That is, for example, the main unit has only a connection portion with the modem, and the modem is separated from the main device. Alternatively, only the connection portion with the TV tuner is provided in the main body, and the TV tuner is separated from the main body device. Or, in the main unit only have a connection to the hard disk,
