1 is a conceptual diagram illustrating a method for upgrading software of a digital broadcast receiver according to the present invention.

Referring to FIG. 1, when the software stored in the broadcast receiver 110 is to be upgraded to improve the performance of the digital broadcast receiver 110, the manufacturer of the corresponding broadcast receiver 110 may upgrade the software of the broadcast receiver 110. It generates and transmits to the broadcasting station 100.

Then, the broadcasting station 100 loads the upgrade software transmitted from the manufacturer on the broadcast signal and transmits the upgrade software to the broadcast receiver 110.

Here, the software code included in the broadcast signal includes a header part including basic index information about the software code and a payload part including the actual software code in the form of a packet.

The header unit records a manufacturer name and a model name of the digital broadcast receiver 110 to confirm a receiver that has performed a software upgrade, a receiver confirmation code, version information indicating a software version, and a payload for recording a payload length. And a length guide, a version guide for recording guide information on the current software version information, and upgrade period information indicating an upgrade period of the corresponding software.

When the broadcast signal is received from the broadcast station 100, the broadcast receiver 110 analyzes the broadcast signal to determine whether a software code is inserted. If the software code is inserted into the broadcast signal as a result of the determination, the broadcast receiver 110 determines whether the software code is a downloadable code suitable for the model of the corresponding receiver.

That is, the broadcast receiver 110 determines whether the software code corresponds to the model of the corresponding receiver by using the receiver identification code of the header of the software code.

As a result of the determination, if the receiver confirmation code is a software code corresponding to the model of the corresponding receiver, the broadcast receiver 110 determines whether a newer version is stored than previously stored software by using version information of the header part. As a result of the determination, if the version information is a new version, the broadcast receiver 110 queries the user whether to perform a software upgrade by using an OSD.

If the user selects the upgrade, the broadcast receiver 110 immediately performs a software upgrade, and if the user chooses to cancel the upgrade, the broadcast receiver 110 stores the upgrade software information including the current channel information. The upgrade software information includes channel information including software to be upgraded and upgrade period information that can be upgraded.

Subsequently, when the user intends to manually perform a software upgrade, the broadcast receiver 110 may output the stored upgrade software information, and the user may view the output upgrade software information so that the software upgrade may be performed. .

A broadcast receiver that performs the above role will be described in more detail with reference to FIG. 2.

Referring to FIG. 2, a broadcast receiver capable of manually upgrading software includes a tuner 200, a demodulator 205, a demultiplexer 210, an audio decoder 215, an audio processor 220, a video decoder 225, and a video. The processor 230, the display unit 235, the additional information processor 240, the controller 245, the storage 250, and a key input unit 255 are included.

The tuner 200 converts the radio signal transmitted through the antenna into an IF signal according to the analysis information of the remote control code selected by the user, and transmits the radio signal to the demodulator 205.

In addition, the tuner 200 serves to tune the frequency of the broadcast signal corresponding to the selected channel under the control of the controller 245.

The demodulator 205 demodulates the signal tuned by the tuner 200 to correct an error and converts the signal into a transport stream.

The demultiplexer 210 demultiplexes the time multiplexed transport stream into video, audio, and additional information signal sequences.

The audio / video decoders 215 and 225 extend / restore the video and audio signal sequences separated by the demultiplexer 210.

The audio processor 220 converts the audio signal output from the audio decoder 215 into an analog audio signal to be output through a speaker.

The video processor 230 converts the video signal output from the video decoder 225 into luminance and color signals so as to be displayed on a screen.

The video processor 230 allows the upgrade software information stored in the storage unit 250 to be output through the display unit 235 in the form of an OSD or the like under the control of the controller 245.

The storage unit 250 includes a flash ROM for storing software such as an operating system and a DRAM for storing a virtual screen in a bitmap form that can be represented in a CRT area.

In addition, when the user cancels the software upgrade, the storage unit 250 stores upgrade software information including channel information and upgrade period information on the software whose upgrade is cancelled. The stored upgrade software information is displayed on the display unit 235 when the user manually upgrades the software later.

The key input unit 255 receives a command desired by the user.

The additional information processor 240 analyzes the additional information separated by the demultiplexer 210 to determine whether there is software to upgrade. That is, the additional information processor 240 determines whether there is software to be upgraded in the PSI analyzed by the demultiplexer 210. The additional information processing unit 240 checks the version information in the software code of the PSI and, if an upgrade is required, displays a query screen on whether to execute the software upgrade through the display unit 235.

The controller 245 performs overall control of the broadcast receiver. The controller 245 controls the tuner and generates a channel map.

In addition, if there is software to be upgraded as a result of the analysis in the additional information processing unit 240, the controller 245 asks the user whether to upgrade the software and performs upgrade or upgrade software information according to a user command according to the query. If the software upgrade menu is selected by the user through the key input unit 255 later, the stored upgrade software information is output to upgrade the corresponding software according to a user command.

Hereinafter, a method of upgrading software by the broadcast receiver configured as described above will be described.

When a broadcast station sends a broadcast signal including upgrade software information to the broadcast receiver, the broadcast receiver is transmitted to the demultiplexer 210 through the tuner 200 and the demodulator 205.

The demultiplexer 210 separates the received broadcast signal into audio, video, and additional information. The separated additional information is transmitted to the additional information processor 240, and the additional information processor 240 analyzes the additional information to determine whether there is software to upgrade.

That is, the additional information processing unit 240 determines whether a software code exists in the additional information. If the software code exists as a result of the determination, the additional information processing unit 240 determines whether the software code is a downloadable code suitable for the model of the corresponding receiver. That is, the additional information processor 240 determines whether the software code corresponds to the model of the corresponding receiver by using the receiver identification code of the header part in the software code.

As a result of the determination, if the receiver confirmation code is a software code corresponding to the model of the corresponding receiver, the additional information processing unit 240 determines whether a newer version is stored than previously stored software using the version information of the header unit. As a result of the determination, if the version information is the new version, the control unit 245 causes the display unit 235 to display a query screen indicating whether to upgrade the software.

The user looks at the displayed screen to determine whether to upgrade the software.

If the user selects to execute the software upgrade now, the controller 245 controls the software upgrade to be normally performed.

If the user selects to cancel the software upgrade, the controller 245 causes the current channel information and the upgrade period information to be stored in the storage 250 and cancels the software upgrade.

Later, when the user selects a manual software upgrade menu through the key input unit 255, the controller 245 retrieves upgrade software information stored in the storage unit 250 and displays the upgrade software information on the display unit 235. .

When the user selects a software upgrade command through the displayed screen, the controller 245 compares whether the current channel is the same as the channel (channel information in the upgrade software information) stored in the storage 250. As a result of the comparison, if the current channel is the same as the channel stored in the storage unit 250, the controller 245 immediately performs a software upgrade.

If the current channel is not the same as the channel stored in the storage unit 250 as a result of the comparison, the controller 245 controls the tuner 200 to change the current channel to the stored channel, and stores the If the channel is changed, upgrade the software.

If the software code is inserted into the broadcast signal as a result of the determination, the digital broadcast receiver determines whether the software code is a downloadable code that matches the model of the receiver. That is, the digital broadcast receiver determines whether the software code corresponds to the model of the corresponding receiver by using the receiver identification code of the header of the software code.

As a result of the determination, if the receiver confirmation code is a software code corresponding to the model of the corresponding receiver, the digital broadcast receiver determines whether the new version is newer than previously stored software by using version information of the header unit. If the version information is a new version, the digital broadcast receiver determines that there is software to be upgraded.

As a result of the determination in step 302, if there is software to be upgraded in the broadcast signal, the digital broadcast receiver displays a software upgrade execution query screen inquiring the user whether to perform a software upgrade (S304).

The software upgrade execution query screen is displayed in the form of an OSD, etc. The software upgrade execution query screen includes a software upgrade execution command and an upgrade cancel command. If the user wants to upgrade the software immediately, he selects the execute command, and if he does not want to upgrade, he selects the cancel command.

When the user selects an upgrade execution command through the screen displayed in step 304 (S306), the digital broadcast receiver executes a software upgrade (S308).

If it is determined in step 306 that the user does not want to upgrade the software and selects a cancel command, the digital broadcasting receiver stores upgrade software information including current channel information (S310) and does not perform the software upgrade (S312). ). The upgrade software information includes a channel number through which software to be upgraded is transmitted and an upgrade period.

That is, when the user cancels the automatic software upgrade, the digital broadcasting receiver stores the upgrade software information so that the user can manually upgrade the software later. Will be displayed. The period and channel information is useful for the user to determine the software upgrade.

If the software upgrade period has passed, it indicates that there is no software to upgrade. By informing the user that the software cannot be upgraded, the user does not need to search whether there is software to upgrade.

According to another embodiment of the present invention, if the user does not want to upgrade the software, the digital broadcast receiver stores the upgrade period and the corresponding software. Then, in the future, when the user manually selects the software upgrade, the digital broadcasting receiver may display the upgrade period and the corresponding software information so that the upgrade may be automatically performed using the stored software.

When the user selects the software upgrade menu when the upgrade period and the software are stored as described above, the digital broadcasting receiver displays an upgrade software information providing screen displaying the upgrade period. The user sees the upgrade period and upgrades the corresponding software.
