The present invention relates to a broadcast receiver, and more particularly, to a broadcast signal, a processing method, and a broadcast receiver for displaying software download related information.

In particular, conventional digital broadcast receivers are released with appropriate software embedded at the time of product release. In this case, the software means software for controlling the operation of the digital broadcast receiver and the user, such as a user interface, or the digital broadcast receiver itself.

The software means, for example, a program that is directly or indirectly related to system operation of a television, and is required to upgrade the software in order to further improve its performance or to change the user environment.

There are various ways to upgrade the software of the digital broadcasting receiver.

First, there is a method in which a serviceman of a manufacturer who manufactures the digital broadcasting receiver directly upgrades the software.

Second, there is a method in which the user accesses the manufacturer's website and downloads and upgrades.

Third, there is a method in which the software of each manufacturer is included in the broadcast signal, and the broadcast receiver extracts the corresponding software from the broadcast signal transmitted from a broadcasting station or the like and automatically performs a software upgrade process.

However, the third method is called an over the air method, and in some cases, the term OAD (Over Air Download) method may be used interchangeably.

In particular, since the software can be transmitted to several digital broadcasting receivers at one time and the procedure is easy from the user's point of view, the interest in the OTA method is amplified.

However, according to the conventional OTA method, there is a problem in the process of downloading the software related to the system drive of the television.

First, compared with the old version of the software, there is no way of informing the user of the feature that is changed through the new version of the software in the downloading process.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.

1 is a block diagram illustrating a configuration of a broadcast receiver for processing a broadcast signal for displaying software download related information according to the present invention.

Referring to FIG. 1, a configuration of a broadcast receiver for processing a broadcast signal displaying software download related information according to the present invention will be described as follows.

The broadcast receiver 100 according to the present invention includes a tuner unit 101, a demultiplexer 102, an audio buffer 103, a video buffer 104, a data buffer 105, an MPEG decoder unit 106, and a signal. The synthesizer 107, the system controller 108, the OSD generator 109, the memory 110, and the user input 111 may be included.

The broadcast receiver 100 may be, for example, a digital broadcast receiver, a DTV, or the like.

The tuner unit 101 is responsible for tuning a digital broadcast channel. In some cases, it may be composed of a plurality of tuners.

The demultiplexer 102 parses MPEG transport streams received through respective services multiplexed on the digital broadcast channel into audio, video, and data.

The audio buffer 103, the video buffer 104, and the data buffer 105 function to temporarily store the audio, video, and data, respectively.

The MPEG decoder 106 decodes the temporarily stored audio, video, and data and restores the original audio and video signal.

The OSD generator 109 generates and outputs an OSD image so that a user can check various broadcast information provided through digital broadcasting.

The signal synthesizing unit 107 performs signal synthesis on the image output through the MPEG decoder 106 and the OSD image.

The system control unit 108 controls the overall operation of each component of the broadcast receiver 100.

The memory unit 110 stores data necessary for the control and the like.

On the other hand, the memory unit 110, an operating program (OS Program) for driving the system of the broadcast receiver, the tuning information required for tuning the broadcast satellite, for example, a frequency corresponding to the broadcast satellite (Frequency) Information, polarization information, symbol rate information, and forward error correction (FEC) information are recorded and stored.

Accordingly, when system power is turned on, the broadcast receiver 100 executes an operating program stored in the memory unit 110 through system booting, and then reads out the tuning information. Then, a series of operations for tuning the broadcast satellite corresponding to the tuning information is performed.

Subsequently, after receiving the MPEG transport stream of the broadcast channel designated by the user, and restoring and signal processing the original video and audio signals, the video and audio signals are transmitted and output to a general television. After processing various broadcast information received through a broadcast channel into an OSD image, the OSD image signal is transmitted and output to a general television.

Meanwhile, according to the OTA method, in the process of downloading specific software, the broadcast satellite outputs a new latest version of the software through service information (SI) of a digital broadcast signal, and the broadcast receiver 100 ) Receives and downloads it, and updates the software pre-stored in the memory unit 110 with the latest version of the received and downloaded software.

In particular, in the present invention, while downloading the software transmitted in the OTA method, the system control unit 108 reads out the data explaining the feature that the new version of the software is changed compared to the old version of the data temporarily stored in the data buffer, One feature is that the new version of the software, via the OSD generation unit 109, displays the changed feature compared to the old version.

However, in the present invention, since the new version of the software intends to define data describing the changed feature in comparison with the old version in two independent methods, it will be described by dividing it into the respective embodiments.

First Embodiment

2 is a diagram illustrating an example of DII data changed according to the present invention.

3 is a diagram illustrating another example of DII data changed according to the present invention.

Hereinafter, referring to FIGS. 2 and 3, a method of inserting data describing a changed feature of a new version of software compared to an old version using DII (Download Info Indication) data is as follows.

In this embodiment (first embodiment), the upgrade contents are periodically displayed in software by inserting the upgrade contents in a specific portion of the DII data in the current OTA standard.

As illustrated in FIG. 2, a download info response and download infoindication message is defined among the DII data.

In particular, in the syntax of the message, the private data byte field is a part that a manufacturer or the like can arbitrarily use, and one feature of the present invention is to define an additional descriptor.

A descriptor to be added to the private data byte field shown in FIG. 2 is illustrated in FIG. 3.

The descriptor shown in FIG. 3 is a descriptor newly defined in the present invention, and will be named, for example, 'upgrade_display_descriptor'. However, the scope of the present invention is not limited only by the name, but is only an example.

The "descriptor_tag" field describes the purpose or meaning of the descriptor and declares that it is an upgrade display descriptor.

The "descriptor_lengrh" field defines the length of the descriptor (for example, the number of bytes, etc.).

The "upgrade_count" field is a field that defines the number of texts describing a feature upgraded in a new version of software compared to an old version.

The "upgrade_text_length" field is a field that defines the length of one text.

The "upgrade_text" field is a field for describing a feature upgraded in a new version of software compared to an old version, and may directly describe the feature in a text type.

When the text type is used, it is sufficient to display the contents of the "upgrade_text" field as it is, so that the user can show the upgraded feature in the new version of the software more quickly than the old version.

In addition, since data describing the upgraded feature of the new version of the software compared to the previous version is defined in the upgrade display descriptor shown in FIG. 3, no error occurs in particular even in a broadcast receiver that does not use the descriptor. There is also an effect that can be maintained.

On the other hand, the system control unit 108, which parses the upgrade display descriptor, reads the "upgrade_text" field and displays the text content on the screen.

For example, if the text content is a function of 'correcting and supplementing a digital channel skip error during channel tuning', the system controller 108 controls the OSD generator 109 to display a screen as shown in FIG. 4. Design to display

Alternatively, the upgrade display descriptor may be stored in the memory unit 110 and then repeatedly displayed while receiving DDB data (for example, about 10 minutes).

Whenever 5 or 10 pieces of the DDB data are received, it is also possible to replace the contents of the upgrade and send them to the manufacturer.

5 is a diagram (flow chart) showing an example of a control method for processing a broadcast signal for displaying software download related information according to the present invention.

Hereinafter, referring to FIG. 5, the description of the above-described FIGS. 2 to 4 will be described schematically according to the flow of time from the viewpoint of SI information, OTA information, and a user interface.

The broadcast receiver first obtains PMT (Program Map Table) information in the SI information (S501).

Among the SI information, it is checked whether OUI (Organization Unique Identifier) information exists (S502).

As a result of the check (S502), if the OUI information does not exist, it is determined that the OTA service information is not transmitted (S503).

On the other hand, if the check result (S502), the OUI information is present, the model name and version of the software to be transmitted is checked (S504).

If the check result (S504), the model name is different or the version is not the latest version, the procedure is terminated (S505).

On the other hand, when the check result (S504) and the model name are the same and the version is the latest version, the DSI (Download Server Initiate) data is processed (S506).

The DII (Download Info Indication) data is processed (S507).

However, since the DII data includes the upgrade display descriptor shown in FIG. 3, the upgrade contents of the software are stored in the memory unit (S508).

For reference, the upgrade contents of the software mean that, for example, a new version of the software related to the system driving of the television is changed compared to the old version of the software.

It is determined whether DDB (Download Data Block) data exists (S509).

As a result of the determination (S509), if there is no DDB data, it is determined that the OTA service information is not transmitted (S510).

On the other hand, if the determination result (S509), when the DDB data is present, and displays the screen to determine whether the user downloads the software transmitted in the OTA method (S511).

If the user decides not to download the software, transmission of the OTA service is stopped (S512).

On the other hand, if the user decides to download the software, the DDB data is downloaded (S513).

In operation S514, the upgrade content of the software stored in the memory unit is displayed on the screen while the download procedure is performed.

It is determined whether the download of the software has ended (S515).

As a result of the determination (S515), when the download of the software is finished, the transmission of the OTA service is stopped (S516).

Second Embodiment

6 is a diagram illustrating an example of DDB data changed according to the present invention.

7 is a diagram illustrating an example of a method of identifying whether the data is DDB data indicating software download related information according to the present invention.

8 is a diagram illustrating another example of a method of identifying whether the DDB data indicates software download related information according to the present invention.

Hereinafter, referring to FIGS. 6 to 8, a method of inserting data describing a feature changed by a new version of software compared to an old version using DDB (Download Data Block) data is as follows.

The present embodiment (second embodiment) is to display the upgrade contents by transmitting upgrade contents only when a specific packet is transmitted when transmitting DDB data in the current OTA standard.

As illustrated in FIG. 6, a download data block DownloadDataBlock is defined in a data message payload.

The download data block DownloadDataBlock includes a block data byte field, and substantial information of the software to be downloaded is inserted into the block data byte field.

However, in this embodiment (second embodiment), it is one feature that in the case of a specific block, the upgrade content itself is contained instead of the actual information of the downloaded software.

In the case of a specific block, as the way to contain the upgrade itself, we will propose two methods again.

First, there is a method of using a block number field among the DDB data shown in FIG. 6.

If a common protocol is specified and the block number field has a specific value, the upgrade content is sent so that the actual information of the downloaded software is not particularly affected.

For example, as shown in FIG. 7, in the block number field having a multiple of 5, the block data byte field inserts the upgrade contents. Of course, in another block number field, the block data byte field contains substantial information of the software to be downloaded.

Second, among the DDB data shown in FIG. 6, there is a method of using a reserved field.

For example, as shown in FIG. 8, when the reserved field has a value of '0', the block data byte field of the DDB data includes substantial information of software downloaded.

On the other hand, when the reserved field has a value of '1', the block data byte field of the DDB data is set to insert upgrade contents.

Of course, the value is only one example, and may be changed to another value.

The reserved field may also be referred to as a "display_block_identifier" field.

For reference, in the embodiment (second embodiment), since the size of the text is not very long, there is no problem in the speed of downloading the software, no new descriptor is required, and the software (S / W This has the advantage of not having to run a loop.

On the other hand, if the block number field or the reserved field (display block identifier field) is read, and the DDB data is determined to be a block containing upgrade contents, the corresponding contents are immediately displayed on the screen.

For example, if the content is a function of correcting and supplementing a digital channel skip error during channel tuning, the system controller controls the OSD generator to display a screen as shown in FIG. 4.

It is also an advantage of the embodiment (second embodiment) that the software upgrade can be designed so as not to be stored in a memory unit or the like.

9 is a diagram (flow chart) showing another example of a control method for processing a broadcast signal for displaying software download related information according to the present invention.

Hereinafter, referring to FIG. 9, the description of the above-described FIGS. 6 to 8 will be described schematically according to the flow of time from the viewpoint of SI information, OTA information, and a user interface.

The broadcast receiver first obtains PMT (Program Map Table) information among SI information (S901).

Among the SI information, it is checked whether OUI (Organization Unique Identifier) information exists (S902).

If the check result (S902), the OUI information does not exist, it is determined that the OTA service information is not transmitted (S903).

On the other hand, if the check result (S902), the OUI information is present, the model name and version of the transmitted software is checked (S904).

If the check result (S904), the model name is different, or the version is not the latest version, the procedure is terminated (S905).

On the other hand, when the check result (S904) and the model name are the same and the version is the latest version, the DSI (Download Server Initiate) data is processed (S906).

Next, DII (Download Info Indication) data is processed (S907).

In operation S908, it is determined whether DDB (Download Data Block) data exists.

As a result of the determination (S908), when the DDB data does not exist, it is determined that the OTA service information is not transmitted (S909).

On the other hand, if the determination result (S908), when the DDB data is present, and displays the screen to determine whether the user downloads the software transmitted in the OTA method (S910).

If the user decides not to download the software, transmission of the OTA service is stopped (S911).

On the other hand, if the user decides to download the software, the DDB data is downloaded (S912).

Then, while the download procedure is in progress, the upgrade contents of the software are read from the DDB data shown in FIG. 6 and displayed immediately (S913).

Alternatively, the software may be designed to read the upgrade contents of the software and store them first in the memory unit (S914).

For reference, the upgrade contents of the software mean that, for example, a new version of the software related to the system driving of the television is changed compared to the old version of the software.

It is determined whether the download of the software has ended (S915).

As a result of the determination (S915), when the download of the software is finished, the transmission of the OTA service is stopped (S916).

The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, modifications can be made by those skilled in the art to which the invention pertains, and such modifications are within the scope of the present invention.

And, the above-mentioned numerical value is a preferred embodiment or merely an example, the scope of the present invention is not limited to the numerical values, and as can be seen in the appended claims, Modifications are possible by those skilled in the art and such modifications are within the scope of the present invention.

The effects of a broadcast signal, a processing method, and a broadcast receiver for displaying software download related information according to the present invention described above are as follows.

Firstly, according to the present invention, while downloading software related to system driving of a television, information about a feature changed by the software is displayed, thereby improving convenience and reliability of the television user.

Second, according to the present invention, there is an effect that can display the information about the characteristics changed by the software without significantly changing the existing OTA standard.

Furthermore, when the descriptor is added to the DII data of the OTA, compatibility with the existing product and other products can be maintained.

In addition, when a new field is defined in the DDB data of OTA, the text length does not increase relatively much, so it does not affect the software download speed and does not have to run a separate loop in software. There is this.
