the output tasks comprise a multi-object synchronous output mode and a single-object synchronous output mode, wherein the multi-object synchronous output mode represents that a plurality of television terminals in the group output object data at the same time, and the single-object synchronous output mode represents that a single television terminal in the group executes the output tasks.
8. The multi-terminal synchronization method of a digital television according to claim 5, further comprising the steps of:
the method comprises the steps of monitoring actions of a user through a sensor group and judging the actions, generating a terminal switching control signal if a user action judging result is characterized as pause output, and generating a switching output control signal if the user action judging result is characterized as continuous output and the terminal switching control signal is executed currently;
and monitoring and judging the behavior action of the user through the sensor group, generating a terminal switching control signal if the sight of the user leaves the television terminal, and generating a switching output control signal if the terminal switching control signal is executed currently and the sight of the user is monitored to return to the television terminal.
