Input, the password strength is higher than the pure digital password, which is different from the general IPTV only digital password input, which meets the password complexity requirements of other platform application services.

The IPTV (Internet Protocol Television) virtual keyboard is currently the main input device of the remote control. The upper, lower, left, right or other buttons of the remote control are used to move the selection keys of the virtual keyboard to further enter the function of inputting text. Various keyboard arrangements have been proposed, mainly for the convenience of use, reducing the number of keyboard button movements. However, there is less innovation and research on the issue of screen keyboard password entry to prevent peeks.

Password input protection, in the online banking, ATM and other touch screens, usually a fixed keyboard, others can easily see the input password from the side, so there are patents randomly generated in the keyboard order: 201112056. But the keyboard is The numeric keys are dominant, and passwords for English and special symbols cannot be entered.

Another patent proposes: 201026057, which allows the user to switch whether the input text is in the secret mode. If it is in the secret mode, the image is displayed with an asterisk (*) instead of the input text. If it is not the hidden mode, the input content is displayed. On the screen. Although this technology replaces the input text with an asterisk (*), this method still does not apply to the IPTV password input, because the screen keyboard is displayed on the screen, and the indicated buttons are still seen by other TV viewers.
