Description

[Technical field]

[0001] The present invention relates to a distribution system that enables residents of an apartment building to watch live outdoor footage on a television or other device. [Background technology]

[0002] Generally, one of the benefits of purchasing or living in a high-rise building such as a high-rise tower apartment or a high-rise rental building is that the view from the apartments, shops, and offices on the higher floors is good and you can enjoy a view that stretches far into the distance. In addition, by overlooking the entire city where the sunlight, sky, street trees, etc. change depending on the season, you can feel the change of the seasons, and when a fireworks display is held in the neighborhood, you can take advantage of the good view and watch the fireworks from home without having to go to the event. Another benefit is that you can check the traffic conditions (road congestion, etc.) and weather conditions in the vicinity, and predict changes in the weather conditions in advance by seeing the sky in the distance.

[0003] However, compared to apartments on higher floors, apartments on lower and middle floors do not necessarily have good views, and are not sufficient for enjoying the expanse of scenery or overlooking the city. On the other hand, even if the apartment is on a higher floor, it is not possible to enjoy the fireworks from an apartment located in the opposite direction from the venue of the fireworks display. In addition, if a high-rise building that blocks the view is constructed nearby after moving in, the view that was previously enjoyable may become difficult to see or may even disappear altogether. When enjoying the view or watching the fireworks, it is sometimes necessary to go out onto the balcony (outdoors) because it is difficult to see from inside the room, but depending on the season, such as midsummer or midwinter, it can be very hot or cold, making it difficult to stay outdoors for a long time.

[0004] If you want to check the traffic conditions in the vicinity, you have to look down from the balcony on a high floor, which is difficult for people who are afraid of heights. Also, if you plan to go out for a short time, such as going out for a quick shopping trip in the neighborhood, you may want to visually check the weather conditions to see if you need an umbrella. However, it is difficult to tell whether it is raining or not from a window located at the back of the balcony, and it is difficult to see the sky on a balcony on an upper floor because the view above is blocked, so it is a hassle to go out to the balcony. Although we have used a high-rise building as an example here, there are also people who live in low-rise or mid-rise apartment buildings who would like to enjoy the scenery and fireworks in a direction that cannot be seen directly from the windows or balconies of their apartments, and who would like to visually check the weather conditions in the vicinity without going out to the balcony. Summary of the Invention [Problem to be solved by the invention]

[0005] To solve the above-mentioned problems, the present invention provides a distribution system that enables each dwelling in an apartment building to watch live outdoor images from inside the building, regardless of the height or direction of the dwelling unit, and without having to endure seasonal cold or heat, so that dwellers can enjoy the view, scenery, fireworks, seasonal atmosphere, etc., and can easily grasp the nearby traffic and weather conditions without going out onto the balcony or looking down. [Means for solving the problem]

Effect of the Invention

[0008] With the distribution system of the present invention, dwellers in apartments, shops, and offices located in high-rise buildings such as high-rise tower apartments and high-rise tenant buildings, as well as other collective buildings, can enjoy the scenery, fireworks, seasonal atmosphere, etc., regardless of the height or orientation of the apartment they occupy, and without having to endure seasonal heat and cold. Furthermore, they can easily keep track of nearby traffic and weather conditions without having to go out onto the balcony or look down. [Brief description of the drawings]

[0009] [Figure 1] 1 is a functional block diagram showing the main configuration of a distribution system according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] A distribution system 1 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram showing the main configuration of the distribution system 1. The present invention distributes outdoor live images captured by a live camera 2 installed outdoors in a high-rise tower apartment in a state where the camera is installed, so that the images can be viewed on vacant channels of televisions and other devices installed in each dwelling unit and store 51, 52, 53, etc. in the high-rise tower apartment, so that the residents of each dwelling unit and store can enjoy the scenery, fireworks, seasonal atmosphere, etc. from their rooms, regardless of the height position or direction of the dwelling unit in which they reside, without having to endure the cold and heat of the season, and can grasp the traffic and weather conditions in the vicinity of the apartment without having to go out to the balcony or look down before going out. In this embodiment, an example of application to a high-rise tower apartment in which dwelling units and stores are located will be described. However, the present invention may of course be applied to other high-rise buildings, such as high-rise tenant buildings in which offices and stores are located, and can be applied to all collective buildings including low- and medium-rise apartments and tenant buildings.

[0011] The distribution system 1 converts the video data of the outdoor live video transmitted in real time by the live camera 2 into an electric signal for independent broadcasting conforming to a broadcast signal for terrestrial digital television broadcasting, integrates the electric signal for independent broadcasting with a broadcast signal of terrestrial digital broadcasting received by a common antenna for receiving broadcasts, amplifies the strength of the integrated signal to a level suitable for viewing on a television or the like, distributes the amplified integrated signal, and distributes it to each of the residences and stores 51, 52, 53, etc. In this embodiment, in addition to a signal obtained by integrating an electric signal obtained by converting a video signal of the outdoor live video into a terrestrial digital broadcast signal for television viewing, an integrated signal obtained by integrating a satellite broadcast signal and a cable television broadcast signal obtained from a cable television is distributed and distributed to each residence. The integrated signal distributed to each residence is branched into a terrestrial digital broadcast signal obtained by integrating an electric signal related to the outdoor live video, a satellite broadcast signal, and a cable television broadcast signal at each residence, so that the signals can be viewed on a receiver such as a television or a recorder.

[0012] As shown in Figure 1, the distribution system 1 comprises a live camera 2 installed on the rooftop R, a PoE-powered switching hub 31 installed in the apartment building's manager's office 3, a camera controller 32, a monitoring unit 33, and an OFDM modulator (modulator) 34 with a built-in HD encoder, an in-building booster 4 with a built-in mixer installed in a common area of ​​the building, a distributor (not shown) that distributes an integrated signal from the in-building booster 4, and a splitter (not shown) that splits the integrated signal distributed to each of the residences / stores 51, 52, 53, etc.

[0013] The live camera 2 is equipped with infrared LED lighting, and captures normal color images during the day and monochrome images as an infrared camera at night, thereby acquiring clear video data of live outdoor images (including audio). The live camera 2 is a so-called PTZ camera, and has pan (P / horizontal swing), tilt (T / vertical swing) and zoom (Z / telephoto / wide-angle adjustment) functions, and can be adjusted in advance by operating the controller 32 installed in the manager's room 3 so that the scenery around the apartment building is accurately captured. Furthermore, an AI application is installed that can automatically swing and focus so that the direction of the image can be periodically changed, or the object of image capture can be changed according to the date and time or the change in brightness around the installation location. Since the live camera 2 is exposed to rain and wind outdoors, it is painted with a material that is highly rust-resistant and can withstand salt damage.

[0014] The live camera 2 is connected to a PoE power supply switching hub 31 via a LAN cable L1 laid from the manager's room 3 to the rooftop R, and receives power from the PoE power supply switching hub 31 while streaming outdoor live video data in real time to the PoE power supply switching hub 31. The PoE power supply switching hub 31 is also connected to a controller 32 and a monitoring unit 33 via LAN cables L2 and L3. The controller 32 has an operation unit (joystick, etc.) for performing pan, tilt, and focus operations on the live camera 2 via the PoE power supply switching hub 31, as well as preset buttons for switching to a preset angle of view and focus with one touch.

[0015] The monitoring unit 33 decodes the video data (RTSP protocol) received from the live camera 2 via the PoE power supply switching hub 31, converts it into a video signal in high definition multimedia interface format, and transmits the video signal to the OFDM modulator 34 connected by a cable L4 for high definition multimedia interface. In order to enable the outdoor live video captured by the live camera 2 to be viewed on a receiver or receiver compatible with terrestrial digital television broadcasting, the OFDM modulator 34 encodes the video signal in high definition multimedia interface format received from the monitoring unit 33, converts it into an electrical signal for independent broadcasting that complies with the terrestrial digital television broadcasting standard (ISDB-T), and transmits it to the in-house booster 4 via a coaxial cable L5.

[0016] The in-building booster 4 is connected to the OFDM modulator 34, and is also connected by separate coaxial cables to a common antenna for receiving terrestrial digital television broadcasting and satellite broadcasting, and to a cable television for receiving cable television broadcasting. The in-building booster 4 has a built-in mixer (not shown) that combines the electric signal for independent broadcasting transmitted from the OFDM modulator 34 and the broadcast signal of terrestrial digital television broadcasting acquired from the common antenna into one integrated signal, thereby enabling outdoor live video captured by the camera 2 to be viewed using an available channel of terrestrial digital television broadcasting. Furthermore, the in-building booster 4 functions as a booster to amplify the strength of the integrated signal that also combines the broadcast signals of satellite broadcasting and cable television broadcasting to a level suitable for viewing using a receiver such as a television or a recorder installed in each apartment in the condominium, and then outputs the combined signal.

[0017] The integrated signal transmitted from the in-building booster (mixer) 4 is distributed by a distributor installed midway along the coaxial cable laid toward each of the dwelling units and stores 51, 52, 53, etc., and the distributed integrated signal is distributed to each of the dwelling units and stores 51, 52, 53, etc. The integrated signal distributed to each dwelling unit, etc. is split by a splitter (not shown) installed in each dwelling unit, etc. into electrical signals (broadcast signals) for terrestrial digital television broadcasting, satellite broadcasting, and cable television broadcasting, and the signals are taken into a television or recorder, so that they can be viewed on a projector or LED display connected to the television or recorder. As a result, the residents of each dwelling unit of a high-rise tower apartment building in which the distribution system 1 is installed can enjoy the scenery, fireworks, seasonal atmosphere, etc. from indoors without having to endure seasonal temperature changes by turning on a television, projector, etc. that they have installed themselves, regardless of the height position or direction of each apartment building, and can be aware of the traffic and weather conditions in the vicinity of the apartment building without having to go out to the balcony or look down before going out.

[0018] (Modification of the above embodiment) In the distribution system 1 according to the embodiment, one live camera 2 having a PTZ function and an AI application is installed on the rooftop, and the direction of shooting is periodically changed, or the shooting target is changed according to the date and time or the change in brightness in the vicinity of the installation location, but a fixed camera without a PTZ function may be used as the live camera. Also, multiple live cameras may be installed to simultaneously shoot different directions or shooting targets, and display them on one screen at the same time. Also, the live camera may be installed in a place other than the rooftop.

[0019] In the distribution system 1 according to the above embodiment, the electric signal for independent broadcasting transmitted from the OFDM modulator 34 is integrated with the broadcast signal acquired from the common antenna, but the electric signal for independent broadcasting may be integrated with the broadcast signal for terrestrial digital television broadcasting acquired from cable television. In addition, in the distribution system 1 according to the above embodiment, in addition to the broadcast signal for terrestrial digital television broadcasting and the electric signal for independent broadcasting, the broadcast signal for satellite broadcasting and the broadcast signal for cable television broadcasting are integrated into one integrated signal, but depending on circumstances such as the installation of an individual receiving antenna for satellite broadcasting in each residence or the like or the installation of a cable television line from an optical cable for telephone, the distribution system may be configured to target only the integrated signal that combines only the broadcast signal for terrestrial digital television broadcasting and the electric signal for independent broadcasting.

[0020] In the distribution system 1 according to the above embodiment, the in-house booster 4 is equipped with a mixer, but the in-house booster and the mixer may be installed separately. In addition, various other embodiments may be adopted within the scope of the present invention without departing from the spirit and scope of the present invention. [Explanation of symbols]
