BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite communication terminal device compatible with multimedia, and more particularly to a composite communication terminal device for performing energization control in block units corresponding to a communication processing state and energization control of the composite communication terminal device. It is about the method.

[0002]

2. Description of the Related Art In recent years, with the progress of communication technology, semiconductor technology, and optical technology, digital lines have been established and high-speed and large-capacity data transmission has become possible. In particular, the characteristics of digital lines are that there is little deterioration in quality due to transmission, there is no need for a transmission line that matches the characteristics of the transmission data media, and the media can be integrated. Multimedia terminals are being commercialized.

For example, an integrated service digital network (IS
With the introduction of DN), communication services have been put to practical use, and AV (Audio Visual) services such as videophones and videoconference systems using such digital lines have been receiving attention.

The above-mentioned service specifications, protocol specifications, and multimedia multiplexing frame configuration specifications for AV services are defined in ITU-T (former CCITT Recommendation) H.264 standard. 320, H.M. 24
2, H.H. It has been announced as 221 mag.

Among these, H. 221 64 Kbps ~
Coded allocation of BAS (Bit Allocation Signal) used for exchange of frame structure and terminal capability in AV service on 1920 Kbps channel, designation of communication mode, etc. is defined.

Further, H. AV using BAS in 242
Protocols such as capability exchange and communication mode switching between terminals are defined. In 320, the system aspect of the entire AV service is defined.

The recommendations given above are end-to-end
After setting the end physical connection and establishing synchronization in the in-channel, multi-process such as image, voice, data, etc. between the terminals by the procedure such as the exchange sequence of the terminal capability using the BAS in the in-channel, the mode switching sequence by the designation of the communication mode, etc. A method for media communication is specified.

As the above-mentioned recommendations are prepared, various products are being developed and commercialized as multimedia terminals by combining independent media until now. For example, various terminals are made.

Of these, in the videophone device, there are functions such as correspondence from still images to moving images, correspondence to high-definition color images, correspondence to writing, and superimposing and editing images from a plurality of video inputs. Prepare, add text by adding, or (Picture in Picture (Pin
Videophone devices with functions such as P) are being made.

Further, due to the progress of storage media, a large-capacity storage medium suitable for storing image data has been developed, and a videophone device having more accurate image data storage and an answering machine function has been also developed. ing.

In addition, an option board has been inserted into a personal computer, and an existing camera, monitor, telephone, FAX, etc. can be combined and used as a TV telephone terminal and can be used.

Further, in the case of a TV conference system, there are not a few cases in which an existing TV monitor, an existing camera, an existing video as a storage medium, and an existing FAX for image transmission are combined.

As described above, although a TV telephone apparatus is realized by combining various functions, there is no terminal that controls the power supply of all the functions.

In addition, a videophone device has been introduced which can remotely turn on / off the power of the other terminal from a remote place. However, this can only be controlled remotely and requires the intervention of the user. The user had to be aware of the power supply of the other terminal.

Further, in recent years, a standard for power supply control is being established from the viewpoint of environmental protection and efficient use of energy, and while power supply control is being carried out in various terminals, the energization time is long and the power consumption is also high. Power control of relatively large multimedia terminals has not been performed very often.

[0016]

However, a drawback common to multimedia terminals typifying the above-mentioned videophone apparatus is that power control cannot be performed despite having many functions. The power consumption is high.

In spite of the fact that the communication terminal has a long energizing time, it consumes a large amount of power, which not only causes a running cost but is also not preferable in terms of the durability of the terminal.

In particular, most of the communication terminals are in a standby state even when the power is turned on, but they are wasting power because they are not controlled. To give an example, although a videophone device with an answering machine has an answering machine and must be energized for 24 hours, it can be used as a monitor, camera, or storage medium other than a communication control device. The power consumption of video and other auxiliary equipment is large, and the user turns on / off the power of each equipment according to the usage status.
It must be turned off, and it is difficult for the user to say that it must be used in consideration of the function and mode to be used.

In addition, the multimedia terminal is a CD-R
Various media such as OM drive, HDD, camera, VTR, and scanner are connected, but it is rare to specify all in practice, but power is supplied to all media. Has been done. For this reason,
It consumes unnecessary power.

Further, with the spread of OS such as Windows (trade name), it is possible to use a plurality of applications on one personal computer at the same time, and it has become possible to handle a large number of applications.

However, since the auxiliary equipment used for each application is different, the auxiliary equipment used for a certain application is always supplied with power even if it is never accessed when operating other applications, and it is useless. It is consuming electricity.

The present invention has been made to solve the above problems, and the objects of the first to ninth inventions of the present invention are to provide a usage status of a plurality of functional blocks and a plurality of application programs. By determining the usage status of each functional block associated with the startup of each function and the usage request status of each functional block that is requested remotely, and controlling the energization from the power supply to each functional block, the required functional blocks can be used according to each usage status.

Embodiments of the present invention will be described with reference to the drawings. [First Embodiment] FIG. 1 is a block diagram for explaining the configuration of a composite communication terminal device according to a first embodiment of the present invention, which corresponds to, for example, a TV telephone device.

In the figure, 101 is a CPU, 102 is a ROM for storing programs, and 103 is a work area R.
AM and 104 are operation units, and have input devices such as a keyboard, a mouse, and a tablet. 106 is a CRT, LCD
It is a display unit including a display device and the like and a VGA controller for controlling the display.

Reference numeral 105 denotes a communication control unit, which performs communication control and is equipped with a microcomputer so that an incoming call can be detected without going through the main control unit. The other party terminal information at the time of an incoming call is brought from the line i / f unit (Ii / f unit) 110 to the communication control unit 105, the operation state of the terminal device is judged from the signal from the communication control unit 105, and the power supply control It is output to the unit 119. The power supply control unit 119 sends a power supply control signal according to the operating state of the terminal device, and controls the power supply for each functional block. 111 is a camera, 113 is an image input / output unit, 11
2 is a video memory.

The block for controlling the power supply may have various forms depending on the system, but in the first embodiment,
122 is a main control block, 123 is a communication control block,
Reference numeral 124 is an image control block, 125 is an audio control block, 126 is a power supply control block, 106, 111, 11
Each 3 is considered a block. Incidentally, recently, some devices have a power-down function, so that each device may be considered as a block.

Next, the operation will be briefly described.

Normally, when the power is turned on, the power is supplied to all blocks. Here, when the communication terminal is no longer used, the state monitoring unit 116 monitors the signal from the operation unit 104 and the communication state from the communication control unit 105 to determine the operating state of the communication terminal. For example, if not used, leave the power control block 126
Energization control is performed to limit power consumption. On this occasion,

On the other hand, the communication control block 123, the image processing block 124, and the audio processing block 125 cannot handle the reception when the power is turned off. Therefore, the power down mode of each element is used (clock is supplied). No, processing such as turning on the power-down terminal) Power consumption is suppressed. Of course, the communication control unit 105 can detect reception. Similarly, the main control block 122 also switches to the power down mode. In this state,
It should save more than the power consumption in normal operation.

At this time, when there is an input from the operation unit 104, the state monitoring unit 116 receives a signal from the operation unit 104, judges the situation, and sends a control signal to the power supply control unit 119. In the power supply control unit 119, the state monitoring unit 11
The power supply of each block is controlled according to the signal from 6.

If received in power down mode,
The communication control unit 105 identifies the capability of the partner terminal via the Ii / f unit 110, sends a signal to the state monitoring unit 116, and the state monitor unit 116 sends a signal to the power supply control unit 119 based on the capability of the partner terminal to operate. Control for blocks For example, when the partner terminal is a telephone, the voice control block 125 and the main control block 122 are put into operation.

In the case of a videophone, the operation can be performed by setting the image control block 124, the display unit 106, and the camera 111 in the operating state in addition to the block during the telephone call.

In a complex communication terminal device in which functional blocks including a control block 124) are respectively connected to a main control block (main control block 122) via a predetermined bus to perform desired complex data processing, a predetermined power is supplied to each functional block. A power supply to be supplied, a monitoring unit (state monitoring unit 116) for monitoring the operating status of the functional blocks, and a power supply level status from the power source to each functional block based on the operating status of each functional block by the monitoring unit. A power supply control unit (power supply control unit 119) for switching control is provided, and the operation status of the functional blocks Based on the operating status of each functional block by the status monitoring unit 116 to be monitored, the power supply control unit 119 controls the switching of the power supply level state from the power supply (not shown) to each functional block, and energizes each functional block. It is possible to control.

A second aspect of the invention is to provide a specifying means (communication control section 105) for specifying a functional block to be used in the functional block from the communication response state with the other party by the communication control block 123, and to provide a power control means (power source). The control unit 119) sets the power supply level state from the power source to each functional block specified by the communication control unit 105 to the normal level,

A process for identifying the capability of the partner terminal when receiving data will be described below with reference to FIGS.

FIG. 2 is a diagram showing a circuit-switched call control procedure (protocol) in the compound communication terminal device shown in FIG. 1, and particularly corresponds to a circuit-switched call control procedure (protocol) in an ISDN circuit.

In the figure, 201 is a calling terminal, 202 is a network, and 203 is a called terminal device (abbreviated as called terminal). Since the present invention relates to the called terminal 203, the description will be made focusing on the called terminal 203. When the calling terminal 201 makes a call, the "call setting" is sent to the network 202, and the "call setting" is made from the network 202. When receiving the "setting", it shifts from the empty state to the incoming call state, returns "call setting acceptance" to the network 202, and shifts to the incoming call acceptance state.

Next, after sending "call" to the network and shifting to the calling state, "response" is sent to enter the response state. Net 202
Upon receiving a "response confirmation" from, the communication state is set. When disconnecting, it receives "disconnect" from the network 202, returns "release", and returns to the empty state when "release complete" is received. here,
The ability of the receiving terminal 203 to determine the capability of the other terminal (that is, the transmitting terminal 201) can be determined when "call setting" is received.

FIG. 3 is a diagram showing an example of the information element format of the ISDN line shown in FIG. 2, and Recommendation I.2 which defines the interface (i / f) between the network and the terminal such as the above "call setting". It corresponds to an example of the format of the layer 3 message of 430.

FIG. 4 is a diagram showing an example of the bit structure of the information element format of the ISDN line shown in FIG. 2, in which the actual "call setting" message is used to switch the channel Blch using the line switching with the μ-law voice. Corresponds to the bit configuration when connected.

As shown in FIGS. 3 and 4, when the receiving terminal 203 shown in FIG. 2 receives the call setting, the ability desired by the other terminal can be discriminated. Therefore, the functional block corresponding to the ability is set to the operating state. By doing so, communication becomes possible.

Proceed to 1) and wait for the end of communication.

On the other hand, if it is determined in step (2) that communication is not in progress, the image control blocks not used in step (3) are P / D (power down mode (hereinafter power down is abbreviated as P / D)). ). The method at this time is to use the P / D (power down) terminal,
There are differences depending on the element used, such as setting the clock frequency to a low frequency or stopping the clock supply.

In step (4), the voice control block is set to P /
Set to D, and step (5) sets the communication control block to P /

If the setting is changed, for example, the camera 111 is handled. In the case of such an application, the camera 111 and the image processing block are set to be turned on in step (14). Hereinafter, canceling the P / D mode will be referred to as ON.

Next, the block power set in step (15) is turned on. In the case of a normal application, since the main control block and the display unit 106 are ON, there is no problem even if they are not particularly switched. If there is no input from the operation unit 104 in step (7), wait for an arbitrary time to elapse in step (8), and if it is determined that there is no input, in step (9) the display unit 106, step ( In 10), P / D of the main control block 122 is set.

Step (16) shows that the P / D mode (absence mode) has been set. In step (17), input from the operation unit 104 is waited for at regular intervals. Operation unit 10

If no call is made, the operation mode is judged to be the PC operation mode, and the PC operation mode is entered in step (28).

On the other hand, when making a call in step (20), the communication control block is turned on in step (21).
In step (22), it is confirmed whether the call is a telephone call or a videophone call. If the call is a telephone call, proceed to step (23) to turn on the voice control block, and turn on the image control block at step (24). And proceed to step (25) to wait for the end of communication. If communication is completed, step (3)

On the other hand, in the case of the TV telephone at step (22), the voice control block is turned on at step (29), the camera 111 is turned on at step (30), and the image control block is turned on at step (31). Go to.

If there is no input from the operation unit 104 in step (17), it waits in step (26) to see if it has been received. If there is no reception in step (26), wait for a fixed time to pass, and if it has passed, step (17)
Return to

On the other hand, if reception is received in step (26), the communication control block is turned on in step (32),
At step (33), the capability of the partner terminal is identified. Here, in addition to those shown in FIGS. 3 and 4, user / user information (UU
It is also possible to perform more complicated control using I) or the like.

Therefore, in step (34), it is confirmed from the result of identifying the partner terminal in step (33) whether or not it is a TV phone. If it is not a TV phone, the voice control block is set to O.
When N, the ringer sound is sounded to notify the user (35).

Next, in step (36), a response is waited for,
If the user answers, answer as a normal phone call in step (38); otherwise, step (37).
Proceed to and send out the voice response message stored in advance,
The voice data from the other terminal is stored. After this, steps (37) and (38) proceed to step (25) to wait for the end of communication.

In the case of the videophone at step (34), the voice control block is changed to step (4) at step (39).
The image control block is turned on in 0), the response is awaited in step (41), and if there is no response, the process proceeds to step (42), in which the image and voice messages stored in advance are transmitted, and the other terminal's The image and voice message are stored, and the end of communication is waited for in step (25).

On the other hand, if there is a response in step (41), the display unit 106 is turned on in step (43), the camera 111 is turned on in step (44), and step (45).
Then, it responds as a normal videophone and waits for the end of communication in step (25).
