First, smart TV generally has an application mall. After installing the software in LeTV market, IKEA market, Android market, etc. , you can find third-party software to install in the market.

Second, it can be installed through sd card (many articles introduce that it can be installed through U disk, but so far I have installed a lot of software, such as 360, application management, etc., and I can't identify the installation package in U disk). The default TV is sd card. If the installation file is copied to sd and the TV can't recognize it, then delete the original program file of sd card, change the name of the file you want to install to the newly deleted file name, and then go to the installation package management in TV to reinstall the installed file.

3. Generally, TVs have cloud hosting. You can register an account, log in on TV and computer at the same time, and then upload the file to the cloud hosting on the computer. The TV will automatically synchronize, showing that the cloud hosting has added files, which can be downloaded and installed on the TV after synchronization.
