The invention disclosed a playing method for a scrambled program and television equipment. The method comprises the steps that after receiving a power off instruction, the television equipment cachesinteraction resources of a CAM card into a preset memory and controls the CAM card to be always in a power supply state; and accordingly, after receiving a power on instruction, the television equipment can acquire the interaction resources from the preset memory and play the scrambled program after being synchronized with the CAM card according to the interaction resources of the CAM card. According to the playing method, after receiving the power off instruction, the television equipment controls the CAM card to be always in the power supply state, and therefore the condition that SAC is triggered to be re-executed is avoided; and after receiving the power on instruction, the television equipment can be synchronized with the CAM card according to the acquired interaction resources, cached when the television equipment is powered on last time, of the CAM card, the synchronization speed of the television equipment and the CAM card is effectively increased, then the STR starting time can be shortened, the playing time of the scrambled program is shortened, and then the quick power on requirement of a user is met.
