Apparatus and method for processing conditional access system-based content

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, from a broadcast providing apparatus, 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, wherein the CAS information includes identification information for identifying at least one of a plurality of CASs;
• generate a uniform resource locator (URL) corresponding to the identification information;
• receive, from an external electronic apparatus, an entitlement control message (ECM) having a preset format based on the CAS information via the communication unit, the external electronic apparatus being different from the broadcast providing apparatus;
• and
• display the content decrypted based on the ECM,
• wherein the at least one processor is further configured to execute the at least one instruction to receive the ECM based on the URL, and
• wherein the CAS information includes CAS data generated in a different format for each of a plurality of broadcasting business operators.

A non-transitory computer-readable recording medium having stored therein a program for performing a method comprising:

• receiving, by a broadcast receiving apparatus, a broadcast stream that comprises content encrypted based on a conditional access system (CAS) from a broadcast providing apparatus;
• extracting, by the broadcast receiving apparatus, from the received broadcast stream, CAS information for decrypting the encrypted content, wherein the CAS information includes identification information for identifying at least one of a plurality of CASs;
• generating a uniform resource locator (URL) corresponding to the identification information;
• receiving, by the broadcast receiving apparatus, an entitlement control message (ECM) having a preset format based on the CAS information from an external electronic apparatus being different from the broadcast providing apparatus;
• and
• displaying, by the broadcast receiving apparatus, the content decrypted based on the ECM,
• wherein the receiving of the ECM comprises receiving the ECM based on the URL, and
• wherein the CAS information includes CAS data generated in a different format for each of a plurality of broadcasting business operators.
