Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a display apparatus, and more
particularly, to a device and method for modifying a video image of
a display apparatus. Although the present invention is suitable for
a wide scope of applications, it is particularly suitable for
efficiently modifying a size and aspect ratio of a displayed video
image.
2. Discussion of the Related Art
In the recent technology, one of the functions of a television
receiver required during the analog-to-digital transition process
of the television environment is the function of enlarging or
reducing an inputted video image and modifying an aspect ratio of
the inputted video image. For example, a wide television receiver
having a picture ratio of 16:9 requires a wide range of video
aspect ratios corresponding to various optional modes, such as a
normal mode (i.e., a video aspect ratio of 4:3) and a wide mode
(i.e., a video aspect ratio of 16:9).
Such optional modes including the normal mode (i.e., video aspect
ratio of 4:3) and the wide mode (i.e., video aspect ratio of 16:9)
are required because the conventional analog televisions include a
television type having a video aspect ratio of 4:3 and another type
having a video aspect ratio of 16:9. In other words, since each
television has a fixed video aspect ratio, the conventional
television is unable to efficiently display broadcast programs
having different video aspect ratios.
More specifically, the related art television has some
disadvantages in displaying moving pictures, such as movies. High
picture quality movies are formed to have a video aspect ratio of
2.35:1. Accordingly, high picture quality images are horizontally
longer than the 16:9 wide screen provided in television screens or
DVD screens. Therefore, a process of modifying the image having an
aspect ratio of 2.35:1 to an image having a video aspect ratio of
16:9. In addition, in televisions having a 4:3 video aspect ratio,
a process of modifying the image having the video aspect ratio of
2.35:1 to a 4:3 video image is required. Similarly, when modifying
a 2.35:1 video image to either a 4:3 video image or a 16:9 video
image, either the left and right portions of the original video
image are cropped or a black screen is inserted on upper and lower
portions of the video image. Therefore, in order to support all of
the various types of movie or motion picture contents distributed
in the market or being broadcasted on television, a more enhanced
and improved video image controlling function is required and
should be developed.

numbers will be used throughout the drawings to refer to the same
or like parts.
FIRST EMBODIMENT
FIG. 1 illustrates the structure of a television receiver according
to the present invention. Although the first embodiment of the
present invention is illustrated as the television receiver, as
shown in FIG. 1, the first embodiment of the present invention is
not limited only to a television receiver but can also include
other types of display apparatuses, such as personal computers
(PC), mobile phones, personal digital assistants (PDA), and so
on.
Referring to FIG. 1, the display apparatus according to the first
embodiment of the present invention includes a combined
analog-digital tuner 1 tuning analog broadcast signals and digital
broadcast signals, a digital video decoder 2 decoding digital
broadcast signals outputted from the combined analog-digital tuner
1, an analog video decoder 3 decoding analog broadcast signals
outputted from the combined analog-digital tuner 1, a video
processor 4 modifying the decoded video signals decoded from the
digital video decoder 2 and the analog digital decoder 3 in
accordance with a resolution of a display 7 and a video aspect
ratio desired by the user, and on-screen display (OSD) generator 5
providing an on-screen display (OSD) for controlling the size of a
video image being displayed, and a screen output unit 6 providing
the video signals formed in the video processor 4 and an OSD image
generated in the OSD generator 5 to the display 7.
The method for modifying a screen by using the screen modifying
device according to the present invention having the
above-described structure will now be described in detail.
The tuner 1 receives broadcast signals of a channel selected by the
user through an antenna, a set-top box or cable receiver. Then, the
digital video decoder 2 or the analog video decoder 3 decodes the
received broadcast signals. The video processor 4 modifies the
decoded broadcast signals received from one of the digital video
decoder 2 and the analog digital decoder 3 to a displayable video
signal in accordance with a predetermined resolution and video
aspect ratio. Subsequently, the screen output unit 6 receives the
video signal outputted from the video processor 4 and provides the
video signal to the display, as shown in FIG. 2A. FIG. 2A
illustrates a video image being displayed when the video aspect
ratio is 16:9. In this case, a black screen is formed on both the
upper and lower portion of the screen.
When the user desires to control the size and ratio of the
displayed video image, the user can modify the size and ratio by
using the control keys of a remote controller or by using the
"Video Image Modifying Menu", as shown in FIGS. 5A and 5B. The
remote controller includes a zoom control key, a normal mode (4:3)
key, a wide mode (16:9) key, and a spectacle control key. When the
user selects any one of the control keys, the OSD generator 5
displays an OSD corresponding to the user-selected control key on
the display 7. For example, as shown in FIGS. 2B and 2C, if the
user selects the zoom control key, the OSD generator 5 displays an
OSD for controlling the size of the video image on the display 7.
Subsequently, the user uses the direction control keys on the
remote controller to select the enlargement ratio for modifying the
size of the video image. The user can control the size of the image
while verifying the changes in the size of the image displayed on
the screen.
The video processor 4 converts broadcast signals to video images in
accordance with the user-specified video image size or video image
ratio. More specifically, depending upon the size and ratio of the
video image desired by the user, the length, width, and
length-width ratio of the video image are modified. At this point,
the video processor 4 enlarges or reduces the size of the video
image and modifies the video image ratio starting from the center
point of the image or screen. Even though the size and ratio of the
video image are modified, the size or shape of the OSD provided
from the OSD generator 5 remains unchanged.
SECOND EMBODIMENT
FIG. 3 illustrates a block diagram of a display apparatus according
to a second embodiment of the present invention.
Referring to FIG. 3, a tuner 102 receives broadcast signals of a
channel selected by the user through an antenna, a set-top box or
cable receiver. Then, a demultiplexer (DEMUX) 103, which is a
signal divider, divides the received broadcast signals into a video
signal, an audio signal, and supplementary information.
The supplementary information includes a Program Association Table
(PAT), Time Date Table (TDT)/Time Offset Table (TOT), and an Event
Information Table (EIT). The PAT includes information on a
plurality of programs, such as information on the program genre,
and TDT/TOT includes the time information for each program. And,
the EIT includes information on title, synopsis, rating, start/end
time, and broadcast time of the programs. Additionally, the
supplementary information also includes subtitle data.
A data processor 106 receives the supplementary information from
the DEMUX103, stores the supplementary information in a memory 108
to a predetermined format, and then provides the supplementary
information to a video processor 104 in accordance with a command
given by the user or a microcomputer 109. Also, the data processor
106 provides an OSD signal to the video processor 104 in order to
display an OSD on a display 105. The video processor 104 receives
the video signals from the DEMUX 103 and receives the supplementary
information and the OSD signal from the data processor 106. The
video processor 104 converts the video signals, the supplementary
signals, and the OSD signals to displayable signals. Also, the
video processor 104 displays the video signals on the display 105.
In addition, the video processor 104 also displays an Electronic
Program Guide (EPG) or subtitles included in the supplementary
information in accordance with the user command. An example of the
EPG is illustrated in FIG. 4.
An audio processor 107 receives an audio signal from the DEMUX 103
and converts the audio signal in order to be outputted through a
speaker 111. A control key input unit 101 receives a user command,
which is transmitted to the microcomputer 109. Then, the
microcomputer 109 controls each member part in accordance with the
user command.
When the user desires to control the size and ratio of the
displayed video image, the user can modify the size and ratio by
using the control keys of a remote controller. As shown in FIGS. 5A
and 5B, the microcomputer 109 displays a "Video Image Modifying
Menu", which is an OSD for setting the size and ratio of the video
image. The "Video Image Modifying Menu" includes items such as
"Size Control", "Ratio Control", "Normal Mode", "Miscellaneous",
and so on. For example, as shown in FIG. 5A, when the user selects
the "Size Control" item, the user either uses the direction control
keys on the remote controller in order to select the reduction
ratio or the enlargement ratio of the image, or arbitrarily inputs
the length and width of the image. Referring to FIG. 5B, when the
user selects the "Ratio Control" item, the user can either select a
desired aspect ratio of the image, or program a new aspect ratio as
desired. Also, when the user selects the "Normal Mode" item, a
normal image is displayed. Finally, when the user selects the
"Miscellaneous" item, the user can change the color of the upper
and lower portions of the screen, which is usually shown as a black
screen. The user can also decide whether to change the size and
ratio of the EPG and the OSD in accordance with the size and aspect
ratio of the image. Furthermore, an option for changing the
location of the subtitles being displayed is also provided
herein.
Depending upon the above-described selections made by the user
through the "Video Image Modifying Menu", the video processor 104
processes the video signal, the supplementary information, and the
OSD signal accordingly. Since the video processor 104 can
separately process the image signal, the supplementary information,
and the OSD signal, the EPG or the OSD may remain unchanged while
the size and aspect ratio of the image is modified.
Even when external signals are inputted to the display apparatus
according to the present invention though an external apparatus,
such as a VCR or a DVD, the video processor 104 can control the
size and aspect ratio of the image in accordance with the user
command.
Moreover, the user can use the "Video Image Modifying Menu" to
program the size and aspect ratio of the video image corresponding
to each genre of the broadcast programs and store the programmed
sizes and aspect ratios within the memory 108. When the size and
aspect ratio corresponding to each genre of the broadcast programs
are stored in the memory 108, the microcomputer 109 verifies the
genre information included in the supplementary information of the
broadcast program and, then, automatically modifies the size and
aspect ratio of the video image of the received broadcast program
based on the genre information, so as to display the modified video
image on the display 105.
As described above, the device and method for modifying a video
image of the display apparatus according to the present invention
provides a "Video Image Modifying Menu" or an OSD window displayed
on the display for controlling the size and aspect ratio of the
video image, thereby allowing the user to efficiently modify the
size and aspect ratio of a displayed image.
It will be apparent to those skilled in the art that various
modifications and variations can be made in the present invention
without departing from the spirit or scope of the inventions. Thus,
it is intended that the present invention covers the modifications
and variations of this invention provided they come within the
scope of the appended claims and their equivalents.
