DIPOL Weekly Review - TV and SAT TV, CCTV, WLAN
No. 28/2012 (Sept. 3, 2012)
The world's largest test of "smart cars". The U.S. Department of Transportation, in cooperation with leading car manufacturers (Ford, General Motors, Honda, Hyundai, Mercedes-Benz, Nissan, Toyota, Volkswagen) and the University of Michigan, has launched tests of "V2V (Vehicle-to-Vehicle)" safety technology. The budget for the tests has been set at $22 million. They will include checking the communication systems between vehicles.
So far, in Ann Arbor, Michigan, about 500 trucks and buses have been equipped with this technology, and they can communicate with each other (V2V) and with elements of the city's infrastructure (Vehicle-to-Infrastructure - V2I). By October, this number will increase to 2800 vehicles.

"Vehicle-to-vehicle communication has the potential to be the ultimate game-changer in roadway safety - but we need to understand how to apply the technology in an effective way in the real world," said David Strickland, NHTSA (National Highway Traffic Safety Administration).
V2V wireless communication can be a major milestone
in the development of active safety of vehicles
In 2011, more than 32,000 people died in the streets of America because of accidents. V2X technology should improve both the safety and efficiency of roads.
After checking the connectivity and communication in real environment, drivers may expect the second phase - development of on-board computer systems, which, after receiving information from nearby cars on their position and speed, will be able, for example, to reduce the speed of the vehicle to a safe limit.
All the vehicles will also exchange information with road infrastructure, a new system of road signs capable of automatic reduction of the speed. Connections with city computers will allow drivers to select the least congested routes.
The range of devices installed in cars and based on advanced electronics and wireless transmission is growing very quickly. Nissan offers vehicles equipped with radars, which in the case of a collision risk can automatically apply the brakes. An interesting system is under development in Volvo. Their wireless system will allow the first car to lead a car convoy. The other drivers will be able to pass the control over their cars to the system and relax while driving e.g. on a highway.

How to easily convert DVB-T signals into PAL channels? Many hotels, motels, boarding houses etc. are equipped with televisions not capable of receiving DVB-T MPEG-4 broadcasts. After analog switch-off the owners of the businesses have to exchange the TV sets (which is expensive), buy external DVB-T receivers - STBs (which may be troublesome - additional devices and remote controls), or solve the problem elegantly and economically by application of a headend converting signals within the antenna system.
The latter alternative can be easily implemented with the use of a simple DVB-T / UHF PAL headend Mixpol DVB-08T R951680. One headend allows for reception of 8 digital channels on any PAL TV sets. The headend can also convert HD channels. It is possible to install more than one headend to receive a greater number of channels.
DVB-T / UHF PAL Headend: Mixpol DVB-08T (8 channels)
8-channel DVB-T / UHF PAL headend Mixpol DVB-08T R951680
An example application of the DVB-08T headend has been shown in the diagram below. DVB-T signals received by the terrestrial TV antenna are split into 3 paths. Two of the paths provide the signals to the R951680 headends. The WWK-951 R89861 multiband amplifier in the third path amplifies the original signals that are then combined with the analog channels provided by the headends and amplified by the broadband amplifier R82303. The original DVB-T signals and 16 PAL channels can be fed to an RF distribution network.

Connections between server rooms or groups of IP cameras. A common problem in IP networks is the need to build high-speed links. Such requirements are imposed, for example, when connecting two server rooms, groups of CCTV DVRs or IP cameras, etc. While the connections of individual computers or IP cameras to network switches can use Fast Ethernet links (100 Mbps), the mentioned earlier cases require the application of Gigabit Ethernet technology.

A modern solution is the use of a fiber optic link. It is quite easy due to the fact that advanced switches are usually equipped with slots for SFP modules. To implement a fiber optic link, the installer needs only a suitable SFP module, indoor or outdoor fiber optic cable and some accessories. The fibers should be terminated with patch cords (arranged in a splice tray placed in a fiber optic box) that are then connected to the switches. There is no need for a fusion splicer - the installer can terminate each fiber using a pigtail and the ULTIMODE L5550 mechanical splice.
The configuration presented below can be used for links up to 20 km.

Wi-Fi via ... power outlet. Powerline Ethernet adapters TP-LINK TL-WPA271KIT N3361 allow network connection through existing power line. The pair or a set of the powerline adapters is an ideal solution in every case where it is impossible to install Ethernet cables or the environment between some points is not suitable for a wireless medium. One of the two units is equipped with wireless access point (AP) providing wireless connectivity for laptops, tablets, smartphones etc.
The user needs as many units as the number of the AC power outlets that are to be simultaneously used as the nodes of the computer network.
An application of the TL-WPA271KIT N3361 devices
The installation of the TL-WPA271KIT is very simple. The "first" one should be connected to the router (with the included network patch cable) and plugged into the nearest power outlet. The second/next adapter is to be connected via its patch cable to the computer in the second/next room and plugged into the nearby power outlet. The maximum length of the electrical wires between the outermost points of the network cannot exceed 300 m. All outlets should use the same branch (phase) of the power network.

TV system in a hotel complex. The owner of a hotel complex with four buildings faced the problem of distribution of television signals from MMH-300 headend to all the buildings.
The best solution was to connect the buildings with single-mode fiber optic cable and use optical transmitters and receivers from Terra. The buildings are spaced about 300 meters apart, so there was no problem with running ducts with universal fiber optic cable ULTIMODE UNI-4SM L7644...

What kind of camera is best to promote towns on the internet? The Municipal Council in Sandomierz, Poland, tests another camera showing the beauty of the town. This time it is a PTZ device operating in auto-patrol mode. The camera has been installed on the council building and provides video stream with resolution of 1280 x 720 pixels. Thanks to compliance with ONVIF standards, the stream can be easily archived on NUUO NVRs or other servers supporting that specification. The images from the camera, with the use of RTSP protocol and streaming server, have been placed on the town's website, together with the player...
