Digital television time lock controlling equipment and method

Abstract

The invention discloses a time locking control device and method of digital television. The method comprises the time locking control with startup system time as control object: obtaining startup system time; determining whether the startup system time is located in the predetermined invalid play time area, if yes, popup user cipher input window, entering television program play after inputting correct the first user cipher, or else, entering directly into television program play. The method also comprises the time locking control with continuous play time length as control object: in the play process of television program, counting the current continuous play time length; determining whether the continuous play time length exceeds the predetermined maximum continuous play time length, if yes, popup user cipher input window, entering television program play after inputting correct the second user cipher, or else, stopping the play of television program. The invention which is independent of condition receiving system of digital television is provided with varied, flexible time locking control.

Description

technical field [0001] The present invention relates to the time locking technology of digital TV, especially relates to a conditional access (CA) system of digital TV, which is independent of the conditional access (CA) system of digital TV, by taking the booting system time or continuous playing time as the control object, combined with popping up the user password input window to prompt input A user password to unlock a time-locked control device and method. Background technique [0002] In order to achieve effective control and management of digital TV program broadcasting, digital TV broadcasting control technology includes a variety of control schemes. [0003] For example, one is to add child locks and age locks to digital TVs through the conditional access (CA) system of digital TVs, and set passwords to limit specific viewing groups, or limit the number of programs watched to achieve control purposes. [0004] Among them, the child lock or age lock is to achieve th...

AI Technical Summary

Problems solved by technology

[0006] 1. Setting the time lock is restricted by the conditional access system;

[0007] 2. Since the child lock and age lock are only a hierarchical control on age groups, and the program lock is a control scheme for a single program, it is less practical when there are various viewing groups in a family

[0009] 1. The setting of the time lock depends on a specific conditional access system;

[0010] 2. Poor control flexibility

Because the time lock can only set the working time period, such as 16:00-18:00, but if the two programs that the user likes are cross-segment, such as the program at 8:00 in the morning and the program at 20:00 in the evening, then It may only be set to 8:00-20:00, or a wider range, so that it will not work as a time limit, unless the setting is changed several times a day

[0011] 3. The change setting of time lock is complicated

If the time lock period has been set, such as 12:00-16:00, and the user suddenly needs to watch the program at this time period, he can only enter the conditional access system to change the setting again, so that the user cannot quickly change the setting
