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.
Claims14
A method for transmitting a service guide in a digital broadcasting system, the method comprising:
- 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.
2 more elements
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.
4 more elements
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.
4 more elements
A terminal in a digital broadcasting system, the terminal comprising:
- a transceiver configured to transmit or receive data;
- and
- a controller configured to:
- control the transceiver to receive 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 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,
- determine 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,
- determine 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,
- control the transceiver to transmit, 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,
- control the transceiver to receive 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
- control the transceiver to receive 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.
6 more elements
A method for receiving a signal by a smartcard in a digital broadcasting system, the method comprising:
- receiving, from a terminal, a first signal indicating that audience measurement (AM) is allowed for a service in the smartcard and a second signal indicating that AM is allowed for a content in the smartcard;
- executing an AM process for the service and an AM process for the content based on the first signal and the second signal;
- reporting first AM data for the service based on the AM process for the service;
- and
- reporting second AM data for the content based on the AM process for the content,
- wherein the first signal and the second signal are determined based on a service guide including the service fragment that includes control information for the service and the content fragment that includes control information for the content, wherein the service fragment includes a first indicator indicating whether the 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.
