Abstract

The data storage system of the multi-function remote control has a priority control unit which controls user data to be stored in memory so that priority data is not lost even if the effective memory capacity is insufficient. When the data protection mode is set, the priority control unit sets the priority of the data and checks the memory capacity when there is an additional data input. When the effective memory is insufficient by comparing the effective memory capacity with the amount of additional input data, the priority control unit controls to increase the capacity of the effective memory by deleting data having the lowest priority. Therefore, in the case of the memory of the same size, it is possible to increase the efficiency of memory use. In addition, by giving high priority to important data, loss of important data can be prevented even when memory capacity is insufficient.

DATA RECORDING SYSTEM IN A MULTI-FUNCTIONED REMOTECONTROLLER}

The present invention relates to a data storage system of a multi-function remote control, and more particularly, by giving a user's arbitrary priority to data stored in the memory of the multi-function remote control so that the high-priority data is not lost even if the effective memory capacity is insufficient. A data storage system of a multifunctional remote controller having a priority control unit for controlling the same.

In recent years, the use of a remote controller (hereinafter referred to as a remote controller) to make it easier and more convenient to operate TVs, TVs, home appliances, etc. has become common, and each home has at least one remote controller. . However, since a separate remote control is used for each device, a remote control capable of performing an integrated function has been developed.

In addition, with the recent development of digital television (hereinafter referred to as DTV), a new technological revolution that may change the existing TV concept is heralded. In addition, the concept that the airwaves are connected to the TV and the public network to the PC will be integrated into a single track along the opening of the information highway. Therefore, TV will be able to perform various active functions including PC function beyond the conventional passive broadcasting reception concept, and accordingly, a new concept of multifunctional remote controller has been developed to perform appropriate functions.

The multi-function remote controller includes an input unit, a controller, a wired communication unit, a wireless communication unit, a speaker, a memory, a display unit, and the like. The input unit may be devices for inputting a signal instructing the operation of the multi-function remote controller such as a key matrix, a touch panel, and a mouse.

The wireless communication unit may wirelessly connect the multifunctional remote controller and a wireless communication base station to exchange information. The speaker outputs a voice or sound under the control of the controller. The display unit outputs an image signal under the control of the controller.

Since the multi-function remote controller performs various operations including wired communication and wireless communication, memory is frequently used. However, since the memory is limited in capacity, there is a limit to the amount of data that can be stored. Despite these limitations, the memory is operated irrespective of the importance of the data stored or to be stored. Therefore, there is a problem that important data is lost when frequently using memory or storing large data. There is a need for a data storage system that can securely store stored data.

The present invention is devised to solve the above-mentioned conventional problems, and the first object of the present invention is to provide a data storage system of a multifunctional remote controller capable of protecting data of high priority, that is, high priority.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The data storage system of the multi-function remote controller according to the present invention includes a mode setting unit 170, a priority control unit 190, a data input unit 110, a memory 130, and a display unit 150.

The data input unit 110 is for inputting data desired by a user. The input data is stored in the memory 130. The display unit 150 displays data on the screen under the control of the priority controller 190. The mode setting unit 170 sets a data protection mode according to a user's request. When the data protection mode is set, the priority control unit 190 outputs a list of data stored in the memory 130 to the display unit 150. The user sets each of the priorities of the displayed data. When the priority is set, the priority control unit 190 searches whether data is input from the outside. If data is being input, the priority controller 190 checks the effective memory capacity of the memory 130. The priority controller 190 compares the checked effective memory capacity with the input data amount and controls to delete data having a lower priority in order to secure insufficient effective memory. When the effective memory is secured as described above, the control unit stores the input data in the memory 130.

According to the data storage method of the multi-function remote control according to the present invention having the system configuration as described above, first, the data protection mode setting step (S210) of setting the data protection mode according to the user's request is performed. When the data protection mode is set, a data list checking step S215 of displaying a list of data currently stored in the memory is performed. When data lists are displayed on the screen, a priority setting step S220 of setting priorities of the displayed data is performed. The priority may be determined at the user's discretion.

Next, a data input determination step (S225) of checking whether there is an additional input of data in a state in which the priority of the data is set, and proceeding to another operation mode is performed when there is no data input. If it is determined that there is an additional input of data in the data input determination step (S225), a memory check step (S230) of checking an effective memory size is performed. When the memory test step S230 is completed, a first determination step S235 of comparing data between the valid memory and the input data and storing the data when the valid memory is larger than the input data is performed. In the first determination step (S235), when the size of the effective memory is smaller than the size of the input data, a shortage calculation step (S240) of calculating an insufficient memory size (N) is performed.

When the size N of the insufficient memory is calculated, the lowest data size checking step S245 is performed to check the size MIN of the lowest data according to the priority of the set data. When the size MIN of the lowest data is checked, a storage determination step S250 of comparing the insufficient memory size N with the size MIN of the lowest data is performed. If the size N of the insufficient memory is greater than the size MIN of the lowest data in the storage determination step S250, the effective memory increasing step S255 is performed to increase the effective memory size by deleting the lowest data. . When the effective memory increase step S255 is completed, the process proceeds to the shortage calculation step S240 to calculate the size N of the insufficient memory again.

Meanwhile, in the storage determining step S250, when the insufficient size N of the memory is smaller than the size MIN of the lowest data, the data deleting step S260 of deleting the lowest data is performed. When the data deletion step S260 is completed, the size of the effective memory increases. Therefore, after the data deletion step S260 is completed, a data storage step S265 of storing the data input in the data input determination step S225 in a memory is performed.

As described above, according to the data storage system of the multi-function remote control according to the present invention, priority is given according to the importance of the data, and when the capacity of the effective memory is insufficient, the effective memory is increased by deleting the low priority data. High ranking data can be protected.

In addition, when the capacity of the effective memory is insufficient, the effective memory is increased by deleting data having a lower priority, thereby increasing the utilization of the memory having a limited capacity.

The present invention is not limited to the preferred embodiments described above, and various changes and modifications are possible by those skilled in the art without departing from the concept and scope of the present invention as defined in the enclosed utility model registration claims.
