Description

Broadcast Receiving Apparatus with Multiple Standby Mode and Power Control Method

The present invention relates to a broadcast receiving apparatus and a power control method thereof, and more particularly, to a broadcast receiving apparatus and a power control method thereof for power saving in an unused time zone.

STB (Set Top Box) receives broadcasting signals through terrestrial, satellite, cable and internet, and separates them into AV contents and outputs them to display devices such as TVs. The power is very high compared to other home appliances.

The operation mode of the general STB can be divided into an on mode that a user watches and a standby mode that does not watch. In the on mode, the broadcast signal is received through a tuner or the Internet, which is then decoded by a media processor and output as audio and video.

On the other hand, in the standby mode in which the user does not watch the STB after turning off the STB by the remote controller, almost all functions are performed in the same manner as the ON mode, and only the audio and video output functions are cut off.

As such, the reason for performing almost all functions in the standby mode is that the broadcaster should receive update information (firmware upgrades, program guides, management information, etc.) transmitted by the SI (Service Informaion) signal while the viewer does not watch the broadcast. Because.

Also, when the user turns on the STB to watch again, it takes a long time for the user to wait until the broadcast screen is displayed, which is a factor that causes the STB to operate almost in the same manner as the standby mode. Accordingly, even if the user turns off the STB by using the remote controller, it consumes 80 to 90% of the power compared to the ON mode.

In a typical STB, 10-15W of power is consumed to watch a broadcast without a storage device or additional tuner. It consumes 8 to 13W while not watching, which is a very high power consumption per year.

Given that most home appliances operate at less than 1W in standby mode, STBs consume a lot of power. However, considering the situation where most advanced countries including Korea regulate the annual power consumption of STB, improvement is required. In the case of improvement, it is important to lower power consumption in standby mode without degrading service quality.

3. STB Operation mode

The STB 100 according to the present embodiment has four operation modes to reduce power consumption. An operation mode transition diagram is illustrated in FIG. 3. As shown in FIG. 3, it can be seen that the four operation modes of the STB 100 are on mode, active-standby mode, passive-standby mode, and off mode.

And STB 100,

1) From 'On Mode' to 'Active-Standby or Off Mode',

2) From 'active-standby mode' to 'on mode, passive-standby mode or off mode',

3) From 'Passive-Standby' to 'On-Mode, Active-Standby or Off',

4) From 'Off mode' to 'On mode',

It can be seen from Figure 3 that it can be switched.

Hereinafter, each of the four operation modes of the STB 100 will be described in detail.

3.1. On mode ( Active Mode )

On mode, the power is supplied to the STB 100, and is a mode that can perform both the 'main-function' and the 'background-function'. In the on mode, the STB 100 may selectively perform the main function and the background function, and may also perform both together.

In On mode,

1) When the user cuts off the power to the STB 100 by turning off the power switch, the STB 100 switches to the off mode,

2) If the user inputs the OFF button or there is no command input from the user for a specific time, the STB 100 switches to the active-standby mode which will be described later.

'Power switch' is a physical switch provided on the back of the STB 100, 'OFF button' is the OFF button provided on the front panel 140 of the STB 100 and the OFF button provided on the remote control, the difference between the two It should be noted that there is.

In the on mode, power is applied to all blocks of the STB 100. Here, all the blocks of the STB 100 are i) all the blocks (110 to 160) provided in the STB 100 shown in FIG. 2, ii) all internal blocks provided in the processor 130 shown in FIG. (130a to 130g), iii) all internal modules (REMOCON module, etc.) provided in the internal blocks (130a to 130g) of the processor 130 shown in FIG.

3.2. Active-standby mode ( Active Standby Mode )

In the active-standby mode, power is supplied to the STB 100, and the main function cannot be performed, and only the background function can be performed.

In active-standby mode,

1) When the user command (regardless of the type of the user command) is input, the STB 100 switches to the on mode,

2) When the power is cut off from the STB 100 by the user turning off the power switch, the STB 100 switches to the off mode,

3) If the set time elapses without performing the background-function, the STB 100 switches to the manual-standby mode which will be described later.

4 is a diagram illustrating a power-on state of the STB 100 in the active-standby mode. In FIG. 4, the hatched blocks are blocks to which power provided by the power supply unit 170 is applied.

As shown in FIG. 4, in the active-standby mode, the blocks necessary for performing the background function are a tuner 110, a demodulator 115, a memory 120, a processor 130, an RTC 135, and a front panel. The power is applied to the 140, the Ethernet interface 150, and the IR receiver 155.

5 is a diagram illustrating a power-on state of the processor 130 in the active-standby mode. The hatched modules in FIG. 5 are modules to which power provided by the power supply unit 170 is applied.

As shown in FIG. 5, all modules of the REMOCON module, the NAND module, the I2C module, and the memory control block 130b of the I / O interface block 130a, which are modules required for performing the background function in the active-standby mode. For example, it can be confirmed that power is applied to all modules of the CPU 130c, the PMU module, the CKC module, the interrupt controller module, the RTC module, and the Ethernet processing block 130g of the system management block 130e.

In active-standby mode, the CPU 130c controls the system management block 130e to clock down, which helps reduce power consumption. As a result, the power consumption of the processor 130 in the active-standby mode is about 1/10 of the on mode.

3.3. Manual-Standby ( Passive Standby Mode )

In the passive-standby mode, power is supplied to the STB 100 and is a mode in which neither the main function nor the background function can be performed. In the manual-standby mode, 'display the current time and the operation state of the STB 100 through the front panel 140,' 'detecting whether a user command is input through the front panel 140 and the IR receiver 155' Can only perform a function.

On the other hand, although not explicitly mentioned above, the above display function and detection function performed in the passive-standby mode is naturally performed in the on-mode and active-standby mode.

In manual-standby mode,

1) When the user command (regardless of the type of the user command) is input, the STB 100 switches to the on mode,

2) When the power is cut off from the STB 100 by the user turning off the power switch, the STB 100 switches to the off mode,

3) When the background-function execution time arrives, the STB 100 switches to the active-standby mode.

6 is a diagram illustrating a power-on state of the STB 100 in the passive-standby mode. In FIG. 6, the hatched blocks are blocks to which power provided by the power supply unit 170 is applied.

As shown in FIG. 6, it can be seen that power is applied to the RTC 135, the front panel 140, and the IR receiver 155, which are blocks necessary for performing the above-described display function and detection function, in the manual standby mode. have.

On the other hand, the operating system and the software operating in the processor 130 is transferred to the memory 120, the memory 120 operates in the self refresh mode. As a result, the power consumption of the processor 130 in the passive-standby mode is several mA.

FIG. 7 is a diagram illustrating a power-on state of the processor 130 in the passive standby mode. The hatched modules in FIG. 7 are modules to which power provided by the power supply unit 170 is applied.

As shown in FIG. 7, in the passive-standby mode, the REMOCON module of the I / O interface block 130a, the PMU module of the system management block 130e, which are modules required to perform the aforementioned display and sensing functions, You can see that power is applied to the RTC module.

3.4. Off mode ( OFF Mode )

The off mode is a mode in which no power is supplied to the STB 100 and no function can be performed. That is, in the off mode, the display function and the sensing function performed in the manual-standby mode are also not performed.

As described above, when the STB 100 switches to the off mode, the user turns off the power switch.

In the off mode, when power is supplied to the STB 100 by the user turning on the power switch, the STB 100 switches to the on mode.

In the off mode, no power is applied to all the blocks of the STB 100.

4. STB Architecture

FIG. 8 is a diagram showing the architecture of the STB 100 shown in FIG. As shown in FIG. 8, the STB 100 may be divided into an application layer 100a, a middleware framework layer 100b, an H / W, and an OS layer 100c.

The application layer 100a is provided with a customer-level power monitoring application, which is an application used for setting a user environment for power control of the STB 100 as well as an application related to the STB 100.

The middleware framework layer 100b includes middleware for unidirectional / bidirectional broadcast processing and a power management bundle, which is middleware for power control.

The H / W and OS layer 100c includes a kernel and a driver for supporting standby mode in addition to the H / W.

5. STB In mode  Transition technique

STB mode switching is a mode switching between the active-standby mode and the passive-standby mode according to a timer and 'external signaling of a high-end (not shown) of a broadcaster providing broadcast and contents'. This will be described in detail with reference to 9.

9 is a flowchart provided to explain an STB mode switching method according to another embodiment of the present invention.

As shown in FIG. 9, when the STB 100 operates in the on mode (S210), when the OFF button is input by the user or no command is input from the user for a specific time (S220 -Y), the processor ( 130 switches the operation mode of the STB 100 from the on mode to the active-standby mode (S230).

Switching from the on mode to the active-standby mode when there is no command input from the user for a certain time can be implemented to be performed only if the user has set in advance.

Power-supply states of the STB 100 and the processor 130 switched to the active-standby mode by step S230 are as shown in FIGS. 4 and 5. In addition, in the active-standby mode, the STB 100 may not perform a main function and may perform only a background function.

The background-function has been described above as including STB S / W update, EIT update, and STB management, where the broadcaster's high-end has external signaling to STB S / W update time, EIT update time and Guide the STB management time.

Therefore, when the STB 100 is switched to the active-standby mode, the CPU 130c of the processor 130 determines the background-function execution time by referring to external signaling received from the high-end of the broadcaster, and manages the system. Notify the PMU module provided in block 130e.

On the other hand, when a user command is input in the active-standby mode (S240-Y), the processor 130 switches the operation mode of the STB 100 to the on mode (S210). On the other hand, if a user command is not input in the active-standby mode (S240-N), the processor 130 determines whether the background function is being performed in the STB 100 (S250).

If it is determined in step S250 that the background function is being performed (S250-N), the processor 130 maintains the operation mode of the STB 100 in the active-standby mode (S230).

On the other hand, if the set time elapses without performing the background function in step S250 (S250-Y), the processor 130 switches the operation mode of the STB 100 to the manual-standby mode (S260).

When the STB 100 enters the passive-standby mode, the PMU module provided in the system management block 130e of the processor 130 operates the RTC 135 according to the background-function execution time determined at the time of switching the active-standby mode. Let's do it.

The power-up state of the STB 100 and the processor 130 which has been switched to the passive-standby mode by step S260 is as shown in FIGS. 6 and 7. In addition, in the manual standby mode, the STB 100 cannot perform the main function as well as the background function.

On the other hand, if a user command is input in the manual-standby mode (S270-Y), the processor 130 switches the operation mode of the STB 100 to the on mode (S210).

On the other hand, if the user command is not input in the manual-standby mode (S270-N), the processor 130 determines whether the background-function execution time has arrived using the RTC 135 (S280).

If it is determined in step S280 that the background-function execution time has arrived (S280-Y), the processor 130 switches the operation mode of the STB 100 to the active-standby mode (S230).

On the other hand, if it is determined in step S280 that the background-function execution time has not arrived (S280-N), the processor 130 maintains the operation mode of the STB 100 in the manual-standby mode (S280).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
