Recommendation ITU-T J.1207 specifies the conformance test of a smart TV operating system over integrated broadcast and broadband cable networks. A smart TV operating system is intended to be installed in an integrated broadcast and broadband (IBB)‑capable cable set-top box (STB) and TV and to enable broadcasting and IP-based interactive services provided by cable television operators and third‑party providers. By running a smart TV operating system, the IBB-capable cable STB and TV will be able to intelligently provide subscribers with advanced and personalized services by downloading and installing advanced and personalized apps from cable operators' platforms and third‑party platforms, which are interconnected with the related cable operators' platforms. Conformance to the smart TV operating system means that it adhere to the relevant requirements of ITU-T J.1201, ITU-T J.1202, ITU-T J.1203, ITU-T J.1204, ITU-T J.1205 and ITU-T J.1206. The TVOS platform should meet the function and architecture’s conformity requirements, security conformity requirements, performance conformity requirements, and interface conformity requirements as described in this Recommendation.
