Abstract
Provided are an apparatus and a method for processing conditional access system (CAS)-based content. A method of operating a broadcast receiving apparatus includes: receiving a broadcast stream that includes content encrypted based on a CAS; extracting, from the received broadcast stream, CAS information for decrypting the encrypted content; receiving an entitlement control message (ECM) having a preset format based on the CAS information generated in a different format for each broadcasting business operator; and displaying the content decrypted based on the ECM.
Claims15
A method of operating a broadcast receiving apparatus, the method comprising:
- receiving a broadcast stream that comprises content encrypted based on a conditional access system (CAS);
- extracting, from the received broadcast stream, CAS information for decrypting the encrypted content;
- receiving an entitlement control message (ECM) having a preset format based on the CAS information generated in a different format for each broadcasting business operator;
- and
- displaying the content decrypted based on the ECM.
A method of operating a broadcast providing apparatus, the method comprising:
- encrypting content based on a conditional access system (CAS);
- generating CAS information for decrypting the content;
- generating an entitlement control message (ECM) in a preset format based on the CAS information;
- transmitting a broadcast stream comprising the content and the CAS information to a broadcast receiving apparatus;
- and
- transmitting the ECM to the broadcast receiving apparatus, according to a request from the broadcast receiving apparatus.
A broadcast receiving apparatus comprising:
- a display;
- a communication unit;
- a memory storing at least one instruction;
- and
- at least one processor configured to execute the at least one instruction to control the broadcast receiving apparatus,
- wherein the at least one processor is configured to execute the at least one instruction to:
- receive a broadcast stream that comprises content encrypted based on a conditional access system (CAS);
- extract, from the received broadcast stream, CAS information for decrypting the encrypted content;
- receive an entitlement control message (ECM) having a preset format based on the CAS information generated in a different format for each broadcasting business operator;
- and
- display the content decrypted based on the ECM.
A computer-readable recording medium having stored therein a program for performing:
- receiving a broadcast stream that comprises content encrypted based on a conditional access system (CAS);
- extracting, from the received broadcast stream, CAS information for decrypting the encrypted content;
- receiving an entitlement control message (ECM) having a preset format based on the CAS information generated in a different format for each broadcasting business operator;
- and
- displaying the content decrypted based on the ECM.
