DVB-NIP (DVB-Native IP) integrates services in 5G and DVB-S2.
In September this year, the DVB specification for native IP transmission, DVB-NIP, was published by the European Telecommunications Standards Institute (ETSI) as TS 103 876 V1.1.1. The publication came just before the annual IBC Show in Amsterdam, where several exhibitors demonstrated the operation of the new standard.DVB-NIP (DVB-Network Independent Protocol) is a technique that enables the transmission of OTT (Over-The-Top), such as video streaming or other multimedia, over existing DVB networks (such as terrestrial DVB-T/T2 or satellite DVB-S/S2). It is a solution that allows the integration of Internet services with traditional broadcast networks, so OTT content can be delivered without relying solely on IP or mobile networks. DVP-NIP also makes it possible to extend the reach of a broadcast network (e.g., DVB-T/T2) by using multiple low-power 5G transmitters in selected areas, which is much more economical and easier to implement than using traditional backhaul transmitters.
DVB-NIP extends the capabilities of traditional satellite broadcasting by making content available in various formats on all IP devices. All services can thus be delivered to an STB receiver, TV, tablet or cell phone. Broadcasting based on the newly developed standard natively combines with terrestrial broadband IP unicast content delivery, meaning that end users will no longer see whether data is being delivered via broadband or satellite, regardless of the platform on which they choose to watch the content.
DVB-NIP leverages many existing IP-based DVB standards. In addition to DVB-I for service discovery and program metadata, DVB-AVC and DVB-DASH are used for encoding and packaging audio/video streams, DVB-MABR for multicast distribution, and DVBGSE for link layer adaptation. At the physical layer, DVB-S2X and DVB-T2 are used. DVB-HB (home broadcasting) standards are also used in some scenarios. To support the migration of existing DVB networks, the DVB-NIP standard also includes a backward compatibility mode option that uses multi-protocol encapsulation (DVB-MPE) to carry IP packets over an MPEG-2 transport stream (e.g., in DVB-S2).
The DVB-NIP standard will significantly simplify the life of the average user, especially in terms of access to multimedia content. Devices such as TVs, set-top boxes and computers will be able to easily work together, thanks to the standardization of data transmission over different networks. This means that whether content is transmitted over cable, satellite or the Internet, the user will be able to receive it without the need for different devices for each platform. Access to selected movies, programs and live broadcasts will become faster and more intuitive, and the integration of devices within a single home network will make it easier to control content from a smartphone or tablet.

Cost-effective monitoring of a single-family house.
The following diagram shows a monitoring system for a single-family house built with Hikvision VE-NC140F-LIU K03036 IP cameras with human object filtering function. The cameras are equipped with image sensors with a resolution of 4 MP and a fixed focal length ensuring a wide viewing angle of 104°. This model uses a hybrid illuminator, which allows it to operate with IR illumination in night mode and turn on white light illumination when a person is detected in a motion detection event. This type of solution makes it possible to deter an intruder and to record important details for identification at night.The DS-7104NI-Q1/M K22024 NVR is used for recording events. The 6-port PoE switch N29978 has been used to establish communication between the devices and power the cameras. The NVR uses the WD Purple M89270 hard drive with a capacity of 2 TB. Support of H.265 compression by the DVR and cameras , allows to store the recordings of 14 days at 20 fps. To access the system from the local and external network, the recorder has been connected to the Mercusys AC12G N2933 router. Locally, the images will be displayed on Hikvision DS-D5022FN00 M29121 monitor. With to the support the Hik-Connect cloud by Hikvision devices, access from an external network is extremely easy and does not require advanced knowledge of network issues.
Using four 4 MP (2560 × 1440 px) cameras, 20 fps continuous recording, H.265 compression set and a profile selected for medium scene complexity, the recordings on the 2 TB hard drive will be kept for about 14 days.
Can G.652.D optical fibers be spliced with G.657.A1/A2 fibers??
In fiber optic installation technology, there can be cables containing fibers in different standards. In LAN, CCTV, automation or FTTH systems one encounters fibers in G.652.D, G.657.A1 or G.657.A2 standard. The G.652.D standard has been used in telecommunications for more than 20 years. The G.657.A fiber group, due to its greater mechanical capabilities (smaller minimum bending radius), was originally intended to be used for last mile sections in FTTH networks. The popularity of cables with these fibers means that today these fibers can be found in almost every system. Installers often ask whether it is permissible to combine (splice) fibers manufactured in different standards.The unequivocal answer is: “yes”. These fibers have the same physical dimensions (sheath, core) and the same tolerance with respect to the size of the so-called module field diameter (MFD), the area responsible for energy transfer in the optical fiber. Thus, they are 100% compatible with each other, and combining them is allowed as much as possible.
Despite the same tolerance range for MFD size, G.657 fibers (and especially A2 fibers) will generally have a smaller mod field diameter. This means that when measured reflectometrically, the splice of G.652.D and G.657.A fibers will generate high attenuation when measured in the A->B direction and a slight apparent gain in the B->A direction. Such measurement results often combined with an ambiguous-looking fiber splice location on the splicer screen (a dark vertical line at the splice location) lead to erroneous conclusions that fiber splicing in different standards is not appropriate. However, it is important to know that the phenomena observed on the OTDR and splicer screens are apparent phenomena that, as a rule, do not affect the proper attenuation of such a splice.
Proof that the aforementioned are 100% compatible with each other can be seen in the fact that large telecommunications operators accustomed for years to G.652.D fibers are gradually beginning to switch to G.657.A1 fibers in certain areas of their networks, often combining new fibers with old ones. In addition, Europe's leading manufacturer of fiber optic cabling, DRAKA, has long used the designation on the sheath of its universal cables: “G.652.D/SM7A1,” so to speak, treating the fibers of the two standards as one and the same.
B2CA cables in low-current systems.
The CPR regulation does not directly apply to the design and construction of buildings, but it does require ensuring the fire safety of buildings, that is, it indirectly requires the use of cables with a certain class of reaction to fire. The CPR regulation does not impose requirements on EU member states related to the use of specific cables in specific buildings. The requirements for using cables with a specific reaction to fire class in a given type of building should be based on a risk analysis made by the installation designer or other national formal and legal documents. Each member state introduces appropriate requirements for buildings on their own.In order to achieve a higher level of fire safety, cable manufacturers recommend the use of B2CA-class cables in special-purpose buildings (especially cables installed within escape routes) that must meet very high safety requirements (e.g., hospitals, nurseries, high-rise buildings, office buildings and nursing homes).
Tri-Shield TRISET 302 B2ca E1006 coaxial cable designed for both individual SMATV systems. The cable is made in LSZH (LS0H) sheath – halogen-free insulation, used where greater safety in case of fire is needed (high-rise and high-rise residential buildings, public utilities).
The following table shows the recommended selection of conductors depending on the size of the building. These recommendations are found in most EU countries.

GSM network as well as GPRS transmission is often used for notifications/readings from meters and communication modules of control panels. When the operator's base station is far away from such a device, there may be problems with adequate signal strength. In order to improve it, a suitable antenna should be connected. Dipol recommends the A7025 model.
