Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image information display apparatus and method suitable for use in a television receiver that continuously records a received program on a recording medium.
[0002]
[Prior art]
While enjoying a television broadcast, it is often the case that a telephone call suddenly rings or a visitor misses the broadcast program. If a television broadcast program is missed, it cannot be viewed again, except for a rebroadcast program. Programs that are rebroadcast in a short period of time are rare, and news programs and sports programs are not rebroadcast in most cases. Therefore, in many cases, if a television broadcast program is missed, the program cannot be viewed again.
[0003]
In addition, scenes that are desired to be saved while watching broadcast programs such as famous scenes of movies and dramas, interviews with important persons, highlight scenes of sports programs, etc. may suddenly start. In such a case, even if the VTR is set immediately, the scene is often not in time and the scene cannot be recorded.
[0004]
Therefore, the present inventor has proposed a television receiver that records a program on a recording medium continuously while watching a broadcast program. In such a television receiver, even if there is a sudden telephone call or visitor, the program can be played back retroactively, so that the program is not missed. In addition, the program can be easily saved, and it is possible to cope with a sudden start of a program to be recorded.
[0005]
Further, the inventor of the present application proposes to use a hard disk drive as a recording medium in a television receiver that continuously records a program on a recording medium. Conventionally, a magnetic tape has been widely used as a recording medium for recording a video signal. However, the magnetic tape has a low access speed and is difficult to use as a recording medium used in such a television receiver. Although semiconductor memory can be used, large-capacity semiconductor memory is very expensive, and the stored program disappears when the power is turned off. It is not suitable for cases where In contrast, a hard disk drive has a large capacity and a sufficiently high access speed.
[0006]
In such a television receiver in which a program is continuously recorded on a recording medium, when a hard disk drive is used as the recording medium, the hard disk drive has a large capacity, so that the program can be stored for a long time. Furthermore, if a video signal is compressed and recorded using a high-efficiency code, recording for a longer time becomes possible.
[0007]
[Problems to be solved by the invention]
However, if the recording time of the program becomes long, it becomes difficult for the user to search for a desired scene. For example, if a hard disk drive having a capacity of about 1 Gbyte is used and a video signal is recorded by compression with motion JPEG, a recording time of about 60 minutes can be secured. However, it is not easy to search for a desired scene from such a long recording screen and reproduce it.
[0008]
In view of this, an image that has been distinguished as an index image is recorded in advance, the index image is read out according to a predetermined procedure, and a search is performed. A method, a method of simply dividing a recording time every predetermined time, and using a representative image for each time zone as an index, etc. can be considered.
[0009]
However, in the method of recording an image that has been distinguished as an index image in advance, and performing a search by reading out the index image according to a predetermined procedure, it is necessary to record a predetermined index image, and the contents recorded on the reception screen are Not applicable when searching. In addition, the method of detecting scene changes on the playback screen and using the place where the scene change occurred as an index requires a correlation detection circuit and a motion detection circuit to detect the scene change, increasing the circuit scale and cost. Invite. In addition, the method of simply dividing the recording time every predetermined time and using a representative image for each time period as an index does not necessarily become a meaningful image that can identify the position of the search image. An efficient search is not possible.
[0010]
In addition, as described above, when the reception screen is recorded on the hard disk drive, since the video data is compressed and recorded, it is difficult to form an index image by simply dividing the recording time every predetermined time. .
[0011]
That is, when the reception screen is recorded in the hard disk drive device in this way, the video data is compressed in order to improve the recording time. As a compression processing method of video data, an MPEG (Motion Picture Experts Group) method and a motion JPEG (Joint Photographics Coding Group) method are known. Although the MPEG method has high compression efficiency, since compression in the time axis direction is performed, it becomes difficult to perform search and variable speed reproduction in field units. Therefore, when recording the reception screen on the hard disk in this way, it is conceivable to compress the video data by the motion JPEG method.
[0012]
However, in the motion JPEG method, the screen compression rate varies depending on the picture or the like. For this reason, when video data is compressed by motion JPEG and recorded on the hard disk drive, the correspondence between the address of the hard disk drive and the recording time cannot be obtained. For this reason, it is not possible to simply obtain the recording time from the address of the hard disk drive, and it is difficult to display the recording time by dividing it into predetermined time intervals.
[0013]
Accordingly, an object of the present invention is to provide an image information display apparatus and method that can easily search for a desired scene or program from a recording screen and that does not increase the circuit scale or increase the cost. .
[0014]
[Means for Solving the Problems]
The present invention divides the moving image information recorded on the recording medium at the first divided time, the recording medium on which the moving image information is recorded, the divided time setting means for setting the first divided time at predetermined intervals , respectively. And dividing the screen area of the display means into a plurality of small screen areas, and indexing the video information divided at the first division time in correspondence with each of the divided small screen areas. Display control means for controlling to display elapsed time in each screen while displaying as an image, input means for designating a desired index image from among index images displayed in a plurality of small screen areas, and an index to update the images, and a offset time setting means for setting the offset time, the display control means, when the index image is designated by the input means, designated The video information corresponding to the index image displayed is read from the recording medium, when updating the displayed index images, dividing means, the second split time obtained by adding the offset time to the predetermined interval, the recording medium Each of the recorded moving image information is divided, and the display control means displays the newly divided moving image information as an index image .
[0016]
The present invention records the video information on a recording medium, a division time setting step of setting a first division time of the predetermined interval, the first split time, the video information recorded on the recording medium each division And dividing the screen area of the display means into a plurality of small screen areas, and indexing the moving picture information divided at the first division time in correspondence with each of the divided small screen areas.

In the control step, the image information display method is characterized in that the newly divided moving image information is displayed as an index image .
[0018]
When the overview search key is pressed, the display screen is divided into a plurality of small screens, and an image of video data recorded on the hard disk drive every predetermined time is divided and displayed on each divided screen. Further, when the overview search key is pressed, the time of each screen is offset every predetermined time. Therefore, a desired reproduction start position can be easily searched from these index screens.

When a time zone for starting moving image reproduction is searched, the enter key 77 is pressed. When the enter key 77 is pressed, as shown in FIG. 3C, a full screen display is displayed, and reproduction of a moving image is started from the screen at the selected time.
[0055]
As described above, according to the present invention, the time zone of the index image associated with the currently reproduced time zone can be visually recognized by making the screen frame color the same. In addition, the time sequence of the index screens displayed on the screens 81A, 81B, 81C, 81D,... Is clockwise in consideration of real life. Further, the elapsed time is displayed on the screens 81A, 81B, 81C, 81D,... Of each index, and the detailed reproduction elapsed time is displayed on the moving image on the central screen 83.

[0056]
As described above, when the overview search key 75 is pressed, the 60-minute recording screen recorded on the hard disk drive 30 is divided, for example, every 5 minutes, and a plurality of screens 81A, 81B, 81C, 81D,.・ Projected in Further, when the overview search key 75 is pressed, each screen is offset by one minute. Therefore, an image serving as an index of the screen that the user wants to search is displayed somewhere on these index screens 81A, 81B, 81C, 81D,..., And a desired reproduction start position is searched from this screen. be able to.
[0057]
FIG. 4 is a flowchart showing processing for easily searching for a desired reproduction start position by dividing and displaying the image information stored in the hard disk drive 30 at predetermined time intervals. It is.
[0058]
In FIG. 4, it is determined whether or not to create an index screen as shown in FIG. 3 based on whether or not the overview search key 75 is pressed (step ST1). When creating an index screen, a division time T, a division interval t, and an offset time n (n = 0) are set (step ST2).
[0059]
The image information recorded on the hard disk drive 30 is divided at time T at every division interval t (step ST3). In the present invention, one field of video data is compressed and recorded in a fixed-length field on the hard disk drive 30. For this reason, the address of the hard disk drive 30 and the recording time have a correspondence relationship. Therefore, the image information recorded on the hard disk drive 30 can be divided at predetermined intervals by a simple address calculation.
[0060]
When the image information of the hard disk drive 30 is divided every predetermined time, the screen is accessed, index images are created from these divided screens, a search screen is created, and these are displayed (step ST4). As a result, as shown in FIG. 3A, an image for each time is displayed on the multi-screen as an index screen.
[0061]
On such a multi-screen, a desired time zone for reproducing a moving image is selected (step ST5), and it is determined whether or not to update the index screen (step ST6). When updating the index screen, the overview search key 75 is further pressed.
[0062]
When updating the index screen, the division offset time n is set (step ST7), and the process returns to step ST3. As a result, as shown in FIG. 3B, the index screen advanced by the offset time n is displayed in multiple screens.
[0063]
If the index screen is not updated in step ST6, it is determined whether or not a screen for starting moving image playback on multiple screens has been determined (step ST8). When the time zone of the screen on which the moving image playback is to be started is set, the enter key 77 is pressed. When the enter key 77 is pressed and the time zone in which video playback is to be started is determined, the video data for that time is read from the hard disk drive 30 and the video is displayed in full screen as shown in FIG. 3C. (Step ST9).
[0064]
As described above, in a television receiver to which the present invention is applied, video data is compressed by motion JPEG so that one field of data has a fixed length. For this reason, it is possible to divide the image information recorded in the hard disk drive 30 every predetermined time or to give an offset time by a simple address calculation. These calculations are performed by the system controller 10, for example, and the hard disk drive 30 is accessed based on the calculation results.
[0065]
That is, in the television receiver to which the present invention is applied, when video data is compressed and recorded in the hard disk drive 30, the image compression circuit 23 performs compression processing so that the compressed data of one field becomes equal. For example, the input video data is dropped into ¼ field, the compression amount for the video data in the same field is tried multiple times, the code amount is estimated, and the quantization table is set so that the predetermined code amount is obtained. It is done by doing.
[0066]
One field of video data having a predetermined code amount is blocked into fixed-length blocks as shown in FIG. As shown in FIG. 5, each block includes video data in which one field is compressed at a fixed length, and audio data, and a predetermined header for identifying the block is provided at the head of each block. In this way, data is recorded in the hard disk drive 30 using the fixed-length block as a file.
[0067]
As described above, since the image of each field is recorded on the hard disk drive 30 as a fixed-length file, the access address on the hard disk 30 of the index image at a certain time T is a field indicating the elapsed time from the recording start time. by converting the de-number can be obtained by simple operations. In other words, the logical address on the hard disk (HDD) is obtained as follows from the start address of the hard disk and the number of fields converted from the elapsed time and the number of block fixed-length sectors.
(Logical address on HDD) =
(HDD start address + (number of fields) x (block fixed sector length)
[0068]
(Logical address on HDD) =
(HDD start address + (number of fields) x (block fixed sector length)
Conversion of the number of fields can be easily calculated because it can be defined by how many seconds of one recorded field corresponds to real time. For example, in the case of reproduction by dropping a frame of 1/4 field, the image data for one field corresponds to about 0.25 seconds.
[0069]
As described above, in the television receiver to which the present invention is applied, when the overview search key 75 is pressed, the 60-minute recording screen is divided, for example, every 5 minutes, and a plurality of screens 81A every 5 minutes. 81B, 81C, 81D,... Further, when the overview search key 75 is pressed, each screen is offset by one minute. Therefore, an image serving as an index of a screen that the user wants to search is displayed somewhere on these index screens 81A, 81B, 81C, 81D,..., And a desired recording position is searched from this screen. Can do. Since the hard disk drive 30 records video data with one field compressed to a fixed length, a playback screen for each time can be displayed by a simple address calculation.
[0070]
In this embodiment, the video data based on the reception screen is stored in the hard disk drive. However, the present invention saves the video data in the semiconductor memory based on another recording medium, for example, the reception screen. as possible out be similarly applied to a case.
[0071]
