RF Connector Types BNC (Bayonet Neill-Concelman) The BNC is a quick disconnect radio frequency connector used with coaxial cable. It features two bayonet lugs on the female connector and a quarter turn coupling nut on the male connector. The majority of board mounted connectors are female while cable mounted connectors tend to be male. Micro BNC The Micro BNC has the same characteristics of the BNC connector in a miniaturised form, which allows significantly higher densities when designing PCB board layouts. The Micro BNC is also known as a they HD-BNC TM or Ultra Tiny BNC. DIN 1.0/2.3 The DIN 1.0/2.3 was introduced in the 1990’s initially for telecommunication application. They feature a push/pull lock and release feature and are suited to applications where space it limited.

How Does Broadcasting Work ? Digital data containing all the information necessary to define a video transmission is sent from a transmitter to a receiver through a transmission media such as air, copper or fibre. The transmitters typically form part of the broadcast infrastructure and the receiver is typically located in the home as a TV or set top box. Television creates the moving pictures by repeatedly sending still pictures called frames, so quickly that your eyes view them as a moving image, as opposed to separate pictures. This is a more technically advanced and faster moving version of a flick book animation. In a television, the frame rate is the number of times in a second that the pictures are refreshed. Most standard televisions refresh the screen at 60 frames per second (60Hz), but 4K televisions may have a 120 or 240 frames per second (120Hz/240Hz) refresh rate. This means that the picture that is shown appears smoother due to the speed of the frames changing. All frames (pictures) are composed of pixels (picture element). The higher the number of pixels in each frame the clearer the final picture will be and images are more defined, hence why this is called the screen definition or resolution. The most common resolutions used now are: 720p - @900 pixels -HD Ready 1080p - @2005 pixels – Full HD 4K - @4000 pixels – 4K UHD TV 8K - @8000 pixels – 8K UHD TV 5
