Abstract

The utility model relates to a set-top box with a monitoring function, which comprises a set-top box body which is connected with a TV in a plugging way, and also comprises a camera device which is connected with the set-top box through signals and is arranged outdoors, and is characterized in that the TV displays images captured by the camera device by specially operating the set-top box body, and the camera device and the set-top box body are connected by a USB interface and wireless signals. The utility model has the beneficial effects that: when the set-top box is in a normal working state, the camera device operates in the background and can not affect the normal viewing of the digital TV; and when someone appears in the monitoring range, a system can automatically popup a prompt, and a user can select a specific operation to switch the pictures of the TV so as to facilitate a master to confirm the identity of visitors in order to select the corresponding operation such as opening the door and the like. The utility model and a residential area monitoring device can form a security system, so that the utility model can send the captured images in the absence of the master to the residential area monitoring device and save to be searched.

Description

A kind of set-top box that has monitoring function

Technical field

The utility model relates to the set-top box technique field, specifically is meant a kind of set-top box that camera head has monitoring function that has.

Background technology

Digital TV set-top box is a kind of conversion equipment that digital television signal is converted to analog signal, it is to the reduction of decoding through the image of digitalization compressed and voice signal, produce the video and the voice signal of simulation, provide high-quality TV programme to spectators by television indicator and stereo set.Along with popularizing and development of digital television techniques, top box of digital machine has become the indispensable equipment in many families parlor.But existing set-top box functionality is quite single, can not adapt to the consumption idea that people improve day by day.

In fact, the inner powerful microprocessor that adopts the advanced person of digital TV set-top box, notion with system realizes all functions, this microprocessor has good expandability, can utilize the advantage of embedded system to expand many economical and practical functions, give the consumer a kind of enjoyment of brand-new digital home, for example video monitoring function.

The utility model content

The problem that the utility model need solve provides a kind of set-top box of supporting video monitoring function.For addressing the above problem, the technical scheme that the utility model is taked is: a kind of set-top box that has monitoring function is provided, comprise the set-top box body of pegging graft with television set, it comprises that also one is connected and installed in outdoor camera head with set-top box signal, makes television set show the image of camera head picked-up by the specific operation to described set-top box body.

Concrete, described camera head adopts USB interface to be connected with the set-top box body or adopts wireless signal to connect.

The beneficial effects of the utility model are: when set-top box is in normal operating conditions following time, camera head is at running background, can not influence normal digital television receiving, in the time of in the people appears at monitoring range, system can eject prompting automatically, and the user promptly can select specific operation to switch TV set image, is convenient to owner and confirms visitor's identity, so that select corresponding operation, as open the door etc.; The utility model can also be formed safety-protection system with the cell monitoring device, with owner not the time image that absorbs send to the cell monitoring system and preserve and wait to look into.

Description of drawings

Fig. 1 forms schematic block diagram for the utility model;

Fig. 2 is that the utility model embodiment one principle is formed schematic block diagram;

Fig. 3 is that the utility model embodiment two principles are formed schematic block diagram.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model is intended to protect a kind of set-top box of supporting to have monitoring function.

As Fig. 1, the described set-top box that has monitoring function comprises set-top box body 10 and external camera head 20 two parts.Existing set-top box generally all has USB interface, therefore utilize this USB interface expansion camera function, be about to have the camera head and the set-top box grafting of USB interface, camera head generally places outdoor (for example on user's door hurdle) and at the set-top box microprocessor corresponding processing program is set, with the storage of the picture that photographs and be prompted to the user, the user can select to check picture as required or carry out other operations.

Because may to have influence on the user indoor attractive in appearance for the USB interface connecting line, so camera head also can take the wireless connections mode with set-top box, for example adopts the transmission of radiofrequency signal and receives the transmission of realization signal.

As Fig. 2, described set-top box body 10 comprises main control chip 11 and the output interface 12, tuner 13, SDRAM and the conventional func modules such as FLASH memory module 14, control panel 15 that are connected with main control chip; Described camera head 20 is connected with main control chip 11 signals, in real time send the image information that photographs to main control chip 11, main control chip 11 carries out analyzing and processing to the received signal, if signal shows the people and enters monitored space, then signal to television set by main control chip 11 and show corresponding prompt information on the television set not influencing under the situation of watching, at this moment owner can select image switching to check or ignore.

When adopting wireless communication mode to connect, at the built-in radio receiving transmitting module of set-top box body, and in camera head also built-in radio receiving transmitting module.Then as shown in Figure 3, described set-top box comprises main control chip 11 and the output interface 12, tuner 13, SDRAM and the conventional func modules such as FLASH memory module 14, control panel 15 that are connected with main control chip, and other comprises the wireless transmitter module 18 that is connected with main control chip 11.The set-top box body is connected with camera head 20 by wireless transmitter module 18, realizes the video monitoring function.

Main control chip 11 is communicated by letter with tuner by the I2C bus form, and tuner 13 output intermediate-freuqncy signals (IF) are input to main control chip 11; Integrated image processing program is also being stored set-top box basic function program in the main control chip 11.The FLASH flash memory module is used for depositing and moving of main control chip program in the memory module, also can be used for storing the image information that photographs.Buffer memory SDRAM cushions when module then is used for program running; Control panel 15 is used to provide the human-computer interaction function of necessity.

Described camera head can be also by the security protection monitoring system communication in radio receiving transmitting module and the user sub-district, and the image information that photographs is sent to the monitoring system of sub-district, the centralized management of realization system.

Radio receiving transmitting module that the utility model is related and camera head all are modules of comparative maturity in the prior art, are not giving unnecessary details at this.
