METHOD FOR MANAGING MEMORY AND
IMAGE DISPLAY DEVICE FOR SAME
TECHNICAL FIELD
[0001] The present disclosure relates to an image display
device and a method of managing a memory by using the
same, and more particularly, allocates and managing an avail
able memory for a plurality of accounts to enable resources of
the image display device to be ef?ciently used.
Oct. 17,2013
Technical Solution
[0008] In one embodiment, a method of managing a
memory according to a plurality of accounts on an image
display device includes obtaining memory management data
according to the plurality of accounts; receiving a command
to store selected data While logged in using the one account;
obtaining information regarding the one account; and dis
playing a memory management menu according to informa
tion regarding the one account.
[0009]
BACKGROUND ART
[0002] An image display device is a device that has, for
example, functions of receiving and processing a broadcast
ing image vieWable by a vieWer. The image display device
displays, for example, a broadcasting program selected by a
user that corresponds to one of broadcasting signals transmit
ted from a broadcasting station. Currently, the transition from
an analog broadcast to a digital broadcast is being globally
made.
[0003] The digital broadcast indicates broadcast for trans
mitting a digital image and audio signal. The digital broadcast
has less data loss, is easy to correct an error, has high resolu
tion and provides a clear screen as compared to the analog
broadcast, because the digital broadcast is resistant to exter
nal noise. In addition, the digital broadcast may provide a
bidirectional service, unlike the analog broadcast.
[0004] The image display device has been enhanced in
performance and has diversi?ed in function to provide the
digital broadcast including a lot of content. In addition, the
enhanced performance of the image display device alloWs a
user to receive an image signal from the broadcasting station
and vieW a related broadcasting program, and further, the
image display device may perform various functions such as
game and music play functions, and an intemet shopping
function by using various applications.
[0005] The image display device enables various applica
tions to be doWnloaded and used and favorite applications
may be different per individual. A multi-user image display
device needs to doWnload and execute applications by
account. The image display device may provide and manage
a login menu by account but, some image display devices
In another embodiment, an image display device for
managing a memory according to a plurality of accounts
includes a storage unit storing memory management data
according to the plurality of accounts; an user interface unit
receiving a command to store selected data While logged in
using the one account; a control unit obtaining information
regarding the one account from the memory management
data and displaying a memory management menu according
to information regarding the one account.
Advantageous Effects
[0010] According to the present invention, since a memory
is allocated and used by account, it is possible to prevent one
account to exclusively use the memory and thus promote
harmony betWeen family members.
[001 1] In addition, according to the present invention, since
When a storage capacity for one account is insu?icient, stor
age capacities for other accounts may be used With reference
to other accounts, it is possible to prevent a lack of memory or
idle memory.

[0149] That is, according to an embodiment of the present
invention, if the user Wants to store selected data, a memory
management menu related to that data may be displayed
along With or independently of the live broadcast.
[0150] FIG. 11A is an example of a memory management
menu according to an embodiment of the present invention. If
a user corresponding to account A With a suf?cient storage
capacity selects the STORE USING ANOTHER ACCOUNT
button 83 in FIG. 10B, or if there is selection by user B With
a insuf?cient storage capacity in FIG. 10C, the image display
device according to the present invention may provide a
memory management menu 90. Referring to FIG. 11A, the
memory management menu 90 may provide a storage capac
ity allocated by account, a in-use storage capacity by account,
and a free storage capacity on the basis of memory manage
ment data. FIG. 11A illustrates that a storage capacity of 25
Gigabyte is allocated to each of accounts A to D, and a free
storage capacity of the accountA is 5 Gigabyte, a free storage
capacity of the account B is 2 Gigabyte, a free storage capac
ity of the account C is 10 Gigabyte, and a free storage capacity
of the account D is 16 Gigabyte. The memory management
menu 90 may include interfaces 91, 92, and 94 for storing data
selected by some of a plurality of accounts. Since a storage
capacity for the account B is insuf?cient, an interface corre
sponding to the account B is illustrated as inactivated. A user
may select one account that is in a logged-in state or may store
selected data by using another account. In FIG. 11A, storing
in the account D is being selected.

The method of managing the memory of the image
display device according to the present invention can also be
embodied as a processor readable code on a processor read
able recording medium, the processor being included in the
image display device. The processor readable recording
medium is any data storage device that can store data Which
can be thereafter read by the processor. Examples of the
processor readable recording medium include read-only
memory (ROM), random-access memory (RAM),
CD-ROMs, magnetic tapes, ?oppy disks, and optical data
storage devices, and also includes being implemented as a
carrier Wave form such as transmission through the Internet).
In addition, the processor readable recording medium can
also be distributed over netWork coupled computer systems
so that the processor readable code is stored and executed in
a distributed fashion.
