HDMI 케이블을 사려는데, 버전 표시가 1.3, 1.3a, 1.3b 제각각이어서 무슨 차이가 있나 알아봤다. 그랬더니,

There is some room for confusion here, and unfortunately, HDMI cable vendors are often just as confused as everyone else—it’s common to see cable labeled “1.3b compliant,” when there is no such thing as HDMI 1.3b, and we are frequently asked whether our cables are 1.3a or 1.3b compliant. But while there is no “1.3b” version of the HDMI spec, the Compliance Test Spec does have a 1.3b version and a 1.3b1 version, as well as a 1.3c version (testing for cables was unaffected by these minor CTS revisions, except that 1.3c adds new criteria for “active” cables)

실제 표준 스펙은 1.3에서 완료되었고, 마이너 리비전은 호환성 테스트 스펙의 개정판일 뿐이다.

광고 문구에 “1.3b Test Spec. Compilant”라고 써야 할 것을 “1.3b Compilant”라고 쓰는 바람에 뭔가 새로운 기능이 추가된 것처럼 소비자를 기망했다는 말이다. 징글징글해.
