“…This paper presents a novel methodology and system for automated functional verification of CAS in integrated digital television sets. It extends the earlier work [4] which designed a system for automated testing of CAS in set-top boxes. In [4] CAS functionality in a single set-top box was verified with the testing methodology based on black-box functional testing system [5].…”

“…It extends the earlier work [4] which designed a system for automated testing of CAS in set-top boxes. In [4] CAS functionality in a single set-top box was verified with the testing methodology based on black-box functional testing system [5]. That testing system was shown to be highly efficient and requires very limited manual tuning related to test procedure adaptations for particular set-top box manufactures.…”

“…The test framework compares each TV response to the reference response and makes decision about the correctness of the CAS operation on the TV's based on the result of the comparison algorithm. The verification algorithms match those for testing of CAS in set-top boxes [4]. In order to support testing of TV sets from different manufacturers and with different response speed, verification algorithms incorporate pop-up detection and Optical Character Recognition (OCR) in order to detect the right moment in which the CAS responded before starting the comparison of the response with the reference response.…”

Conditional access system (CAS) is an essential part of Pay-TV systems, used to restrict access to certain content only to the users who subscribed to that content. Therefore it is useful to have automated verification of CAS system in integrated digital TV sets which contain the conditional access module. This paper presents a novel system for automated verification of CAS in multiple TV sets. The system supports simultaneous verification of 16 integrated digital TV sets produced by different manufacturers. The verification algorithm incorporates pop-up detection and optical character recognition in order to detect when each TV set sends the CAS message. Comparison with the reference image representing the expected response makes decision on the correctness of CAS functionality in the TV set. The system brings speed gain greater than 10 compared to the system which verifies one TV set at a time.
