The present invention proposes a cable digital TV network conversion device and a system upgrade method based on it, wherein the cable digital TV network conversion device includes: a tuner for setting the frequency point for receiving cable digital TV signals; a demodulator for demodulating The tuner is connected with the tuner, and is used to convert the cable digital TV signal received through the frequency point into upgrade data; the controller is connected with the demodulator, and is used to push the upgrade data to the smart device through the communication module, so that The smart device completes the system upgrade according to the upgrade data; the communication module is connected with the controller and used to communicate with the smart device. The wired digital TV network conversion device of the embodiment of the present invention solves the problem that the smart device cannot complete the system upgrade under the condition that the smart device cannot be connected to the Internet.
Description
technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a cable digital TV network conversion device and a system upgrading method based on it. Background technique [0002] In order to achieve richer and more complete functions, a system upgrade is usually performed on a smart device with an operating system. Compared with the previous version, the upgraded system can make up for the system loopholes of the previous version, improve the compatibility of the system, and make the user experience smoother. At present, the system upgrade of smart devices is mainly connected to the Internet through routing wifi signals such as 4G network signals and broadband networks, and the system upgrade package is downloaded to the local area, and then the system upgrade operation is performed. However, if the smart device is currently unable to connect to the Internet, the system upgrade cannot be completed. Contents of the invention...
