Video service system design method based on smart television application and external hardware

The invention relates to the technical field of open intelligent terminals, and discloses a video service system design method based on intelligent television application and external hardware. The video service system comprises an open intelligent terminal, external hardware connected to the open intelligent terminal, and a cloud operation service system. The open intelligent terminal comprises an intelligent terminal operating system and video application software running on the intelligent terminal operating system, and the open intelligent terminal interacts with external hardware and an operation service system. Through interaction between video application software on the intelligent terminal and external hardware, operation service core links such as user identity confirmation, private information management, data encryption and decryption and the like are completed; therefore, the demands of video operators such as telecom and wired video operators for safely and controllably carrying out video servic
