## Abstract

A method for protecting personal information in Audience Measurement (AM) of a digital broadcasting system is provided, including inserting an indicator, which notifies whether a consumption pattern of a service or content provided by a service provider can be measured, into a service guide, to which the information of the service or content is provided by a service provider; and determining whether the AM can be executed for the service or content in accordance with the indicator when the AM function is implemented in a terminal.

generating, by a server, the service guide including a service fragment that includes control information for a service and a content fragment that includes control information for content, wherein the service fragment includes a first indicator indicating whether audience measurement (AM) is allowed or disallowed for the service by a terminal, and the content fragment includes a second indicator indicating whether the AM is allowed or disallowed for the content by the terminal;
transmitting, by the server, the service guide to the terminal;
receiving, by the server, first AM data for the service, from the terminal, if the first indicator indicates that the AM is allowed for the service; and
receiving, by the server, second AM data for the content, from the terminal, if the second indicator indicates that the AM is allowed for the content.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
generating an AM command and transmitting the AM command to the terminal.

### Claim 3 (depends on 1)

The method of claim 1, wherein the terminal is not allowed to perform AM related to the service if the first indicator indicates that the AM is disallowed for the service, or
wherein the terminal is not allowed to perform AM related to the content if the second indicator indicates that the AM is disallowed for the content.

### Claim 4 (depends on 1)

The method of claim 1, wherein the first AM data and the second AM data are generated in a smartcard.

### Claim 5

A server in a digital broadcasting system, the server comprising:
a transceiver configured to transmit or receive data; and
a controller configured to:
generate a service guide including a service fragment that includes control information for a service and a content fragment that includes control information for content, wherein the service fragment includes a first indicator indicating whether audience measurement (AM) is allowed or disallowed for the service by a terminal, and the content fragment includes a second indicator indicating whether the AM is allowed or disallowed for the content by the terminal,
control the transceiver to transmit the service guide to the terminal,
control the transceiver to receive first AM data for the service, from the terminal, if the first indicator indicates that the AM is allowed for the service, and
control the transceiver to receive second AM data for the content, from the terminal, if the second indicator indicates that the AM is allowed for the content.

### Claim 6 (depends on 5)

The server of claim 5, wherein the controller is further configured to generate an AM command and transmit the AM command to the terminal.

### Claim 7 (depends on 5)

The server of claim 5, wherein the terminal is not allowed to perform AM related to the service if the first indicator indicates that the AM is disallowed for the service, or
wherein the terminal is not allowed to perform AM related to the content if the second indicator indicates that the AM is disallowed for the content.

### Claim 8 (depends on 5)

The server of claim 5, wherein the first AM data and the second AM data are generated in a smartcard.

### Claim 9

A method for receiving a service guide by a terminal in a digital broadcasting system, the method comprising:
receiving the service guide including a service fragment and a content fragment that includes control information for a service and a content fragment that includes control information for content, wherein the service fragment includes a first indicator indicating whether audience measurement (AM) is allowed or disallowed for the service in a smartcard, and the content fragment includes a second indicator indicating whether the AM is allowed or disallowed for the content in the smartcard;
determining that the AM is allowed for the service in the smartcard if the first indicator indicates that the AM is allowed for the service in the smartcard;
determining that the AM is allowed for the content in the smartcard if the second indicator indicates that the AM is allowed for the content in the smartcard;
transmitting, to the smartcard, a first signal indicating that the AM is allowed for the service in the smartcard or a second signal indicating that the AM is allowed for the content in the smartcard;
receiving first AM data for the service, from the smartcard, if the first indicator is included in the service fragment and the first indicator indicates that the AM is allowed for the service based on the first signal; and
receiving second data for the content, from the smartcard, if the second indicator is included in the content fragment and the second indicator indicates that the AM is allowed for the content based on the second signal.
