As an example, FIG. 5 is a diagram illustrating a PSIP information table for configuring presence or upgrade data or upgrade data according to another embodiment of the present invention. In the case of EPG data in the PID table of the PSIP information table, 'base_PID (Ox1FFB)' It can be seen that the corresponding PSIP information is EPG data, and as shown in FIG. 6, PID table names according to the data names are '0x0AA1', '0x1DDF', '0x3FFB', '0x4CCA', and the like. By setting the PSIP information table shown in FIG. 5, upgrade data presence information may be configured in the corresponding PSIP information.

In addition, the multiplexer 208 multiplexes the broadcast signal transmitted from the broadcast encoder 202 and the data information (for example, PSIP information) transmitted from the data processor 204 to the broadcast transmitter 210 (step). 404), the broadcast transmitter 210 modulates and transmits (transmits) the multiplexed digital broadcast signal (ie, PSIP information including video and audio signals and EPG data and upgrade data presence information) (step 406).

Next, the tuning and demodulation unit 306 of the broadcast receiving device 106 tunes and demodulates the transmitted digital broadcast signal to restore the transport stream, and the demultiplexer 308 receives the video and audio signals from the restored transport stream. Is extracted and transmitted to the decoding unit 312, and the additional information data inserted on the transport stream is extracted and transferred to the control unit 304 (step 408).

In addition, the decoding unit 312 decodes the video and audio signals, restores the original signal before encoding, and transfers the same to the signal processing unit 316. The control unit 304 parses additional information data, that is, PSIP information, to generate a PSIP information table. Provides a control signal for extracting upgrade data presence information and EPG data through the PID table and generating a corresponding EPG data menu screen to the menu generator 314, and accordingly, the menu generator 314. The generated EPG data menu screen is mixed with the video and audio signals by the signal processor 316 and displayed in OSD mode with broadcast reproduction (step 410). At this time, as shown in FIG. 6, a menu screen such as a PID table name, an upgrade data name, a selection item, etc. may be displayed to select specific upgrade data.

On the other hand, the controller 304 in response to the user inputs a key for requesting the upgrade of the specific upgrade data on the EPG data menu screen on which the upgrade data is displayed by using a remote controller (not shown), the key input unit 302 in response thereto. It is checked whether there is an upgrade request signal generated from 412.

As a result of the check in the step 412, if there is an upgrade request from the key input unit 302, the controller 304 transmits a data upgrade request signal to the communication module unit 318, and accordingly the communication module unit 318 The upgrade request signal is transmitted by accessing the broadcast server 102 through the Internet communication network 108 (step 414).

In addition, the broadcast server 102 provides the upgrade data and its upgrade signal to the data processor 204 through the upgrade processor 206 of the broadcast transmission device 104 according to the upgrade request signal, and the data processor 204. In step 416, the PSIP information is reconfigured as upgrade data and the PSIP information is transmitted to the multiplexer 208 (step 416). For example, at least one of an upgrade request among those indicated by setting '0x0AA1', '0x1DDF', '0x3FFB', and '0x4CCA' as the PID table name according to the data name shown in FIG. 6 in the PSIP information table shown in FIG. PSIP information can be reconstructed with the upgrade data of.

Accordingly, after multiplexing the data signal transmitted from the data processing unit 204 and the video and audio signal transmitted from the broadcast encoding unit 202 and modulating it, the PSIP including the digital broadcast signal (ie, the video and audio signal and the upgrade data) Information) (step 418).

On the other hand, the tuning and demodulation unit 306 of the broadcast receiving device 106 tunes and demodulates the transmitted digital broadcast signal to restore the transport stream, and the video and audio signals from the transport stream restored through the demultiplexer 308. And additional information data are extracted and transmitted to the decoding unit 312 or the control unit 304, respectively, the control unit 304 parses the additional information data, that is, the PSIP information including the upgrade information to generate a PID table in the PSIP information table. After the upgrade data is detected by reference, the upgrade data is stored in the storage unit 310 (step 422).

Subsequently, the broadcast receiving device 106 plays a broadcast program including the video and audio signals decoded and signal-processed by the decoding unit 312 and the signal processing unit 316, and the control unit 304 uses the stored upgrade data. In step 424, data upgrade of the broadcast receiving device 106 is performed. At this time, when the PSIP information including the upgrade data is received, the EPG data menu screen is not displayed because the EPG data is not transmitted.

Therefore, by transmitting a broadcast signal including information on the presence or absence of upgrade data, and displaying the upgrade data according to the EPG data menu screen accordingly, if there is an upgrade request, PSIP information reconstructed the upgrade data with the broadcast signal In this case, data upgrade may be performed by detecting upgrade data in the received broadcast signal.
