  FIG. 9 is a flowchart showing the flow of sleep mode processing in the first embodiment of the present invention. The following description is based on the order of steps shown in the flowchart of FIG.

  The sleep mode management processing unit 26 starts when the user selects “Yes” according to “4. Do you want to start the sleep mode?” On the sleep mode setting screen shown in FIG.

(Step a1)
When sleep mode processing is started by the sleep mode management processing unit 26, the sleep mode management processing unit 26 inputs the level measured by the optical sensor 5 from the optical sensor receiving unit 21, and the level of the input optical sensor is shown in FIG. It is checked whether or not the brightness mode reference data “brightness detection reference value Z” is below.

(Step a2)
When it is determined in step a1 that the level of the input optical sensor is equal to or less than the brightness detection reference value Z, the process proceeds to step a2, and the sleep mode management processing unit 26 causes the communication interface unit 22 to receive a video signal and an audio signal from the external device 6. To check whether the screen is displayed on the TV monitor 3.

(Step a3)
When “brightness detection reference value Z” of the sleep mode setting data is exceeded in step a1, or when a video signal and an audio signal are input from the external device 6 and the screen is displayed on the TV monitor 3 in step a2. Proceeds to step a3, waits for a certain time, and returns to step a1.

(Step a4)
When the screen is not displayed on the TV monitor 3 by the input from the external device 6 in step a2, the sleep mode management processing unit 26 is currently viewed by the user from the program information extracted from the TS packet by the TS decoder 12. Take out the program ID.

(Step a5)
Next, the process proceeds to step a5, and if the sleep mode setting data shown in FIG. 4 includes “presence / absence of sleep mode setting”, the “program ID” of the sleep mode setting data is extracted, and the user extracted in step a4 is currently viewing Check if the program ID is the same as the current program ID. If they are the same, the program that the user is currently viewing is a program for which the sleep mode is set.

(Step a6)
In step a5, when it is determined that the program that the user is currently viewing is a program for which the sleep mode is set, the sleep mode management processing unit 26 performs a process of turning off the power when the timer time elapses. In order to confirm with the user whether to shift to a certain sleep mode, an OSD display command for a sleep mode shift confirmation screen shown in FIG. The OSD processing unit 16 generates a sleep mode transition confirmation screen and outputs the sleep mode transition confirmation screen to the display processing unit 15. The display processing unit 15 superimposes the sleep mode transition confirmation screen generated by the OSD processing unit 16 on the video data decoded by the video processing unit 14, and converts the superimposed video into a television signal. The video is output to the TV monitor 3 and displayed.

(Step a7)

(Step a9)
Next, in step a9, the sleep mode management processing unit 26 checks whether a signal corresponding to the cancellation is output from the remote control receiving unit 20 in order to check whether the user has canceled from the remote control 4.

(Step a10)
If it is determined in step a9 that the user has not canceled from the remote controller 4, the sleep mode management processing unit 26 checks whether the current time is equal to or greater than the power-off time in order to check whether the timer time has elapsed. To check.

(Step a11)
In step a10, when the current time is smaller than the power-off time, the process proceeds to step a11, returns to step a9 as a waiting state for a certain time.

(Step a12)
When it is determined in step a5 that the program currently being viewed by the user is not a program for which the sleep mode is set, or in step a7, the user operates the remote control 4 within t seconds from the sleep mode confirmation screen displayed on the OSD. If it is determined that “No” has been set in step S9, or if it is determined in step a9 that the user has canceled from the remote controller 4, the process proceeds to step a12. In step a12, the sleep mode management processing unit 26 retrieves “whether the power is turned off at the end of the program” of the sleep mode setting data and checks whether the power is turned off at the end of the program. If it is determined that the power is not turned off (no) at the end of the program, this process is terminated.

(Step a13)
In step a12, when it is determined that the power is turned off at the end of the program, the sleep mode management processing unit 26 starts the power-off setting process at the end of the program shown in FIG.

(Step a14)
When it is determined in step a10 that the current time is greater than or equal to the power-off time, or when the program returns from the power-off process due to the end of the program in step a13, the process proceeds to step a14, where the sleep mode management processing unit 26 A command to turn off the power of the broadcast receiving apparatus 1 is sent to 24. The power supply control unit 24 that has received the command turns off the power supply 23, and the process ends.

If it is determined in step a12 of the sleep mode process shown in FIG. 9 that the power is turned off at the end of the program, the “power-off setting process at the end of program” shown in FIG. 10 is started.

(Step b1)
First, the sleep mode management processing unit 26 extracts the program end time of the program that the user is currently viewing from the program information extracted from the TS packet by the TS decoder 12.

(Step b2)
Next, in step b2, the sleep mode management processing unit 26 checks whether the current time is equal to or greater than the program end time in order to check whether the program end time is reached.

(Step b3)
When the current time is smaller than the program end time in step b2, the process proceeds to step b3 and returns to step b1 in a waiting state for a fixed time.

(Step b4)
When it is determined in step b2 that the current time is equal to or greater than the program end time, the sleep mode management processing unit 26 performs an OSD process to confirm to the user whether to turn off the power when the program end time is reached. The OSD display command for the power-off confirmation screen shown in FIG. The OSD processing unit 16 generates a power-off confirmation screen and outputs the power-off confirmation screen to the display processing unit 15. The display processing unit 15 superimposes the power-off confirmation screen generated by the OSD processing unit 16 on the video data decoded by the video processing unit 14, converts the superimposed video into a television signal, and converts it into a TV signal. Output to monitor 3 and display video.

(Step b5)
Next, in step b5, the sleep mode management is performed to check whether the user has selected “Yes” within t seconds or nothing has been selected by operating the remote controller 4 from the power off confirmation screen displayed on the OSD. The processing unit 26 checks whether a Yes signal is output within t seconds from the remote control receiving unit 20 or no signal is output. The sleep mode management processing unit 26 returns to step a14 of the sleep mode processing shown in FIG. 9 if a Yes signal is output from the remote control receiving unit 20 within t seconds or if no signal is output. If the user selects “No” within t seconds by operating the remote controller 4, and if a No signal is output from the remote control receiver 20 within t seconds, the sleep mode management processing unit 26 performs step b1. Return to.
