CCS: Space-Saving Combiners and Switching Systems for Terrestrial Broadcasting Infrastructure

Almost all TV stations share one problem: quite limited space for accommodating transmitting and receiving equipment such as patch panels and combiner systems. The challenges this poses when remodeling or expanding facilities almost inevitably cause delays and considerable extra costs.

A must-have solution: the SPINNER Compact Combining and Switching System (CCS)

The main advantage of the Compact Combining and Switching System (CCS) developed by SPINNER is an exceptionally compact, space-saving design.

In recent years, SPINNER has systematically improved and updated its range of multi-channel combiners and U-links in order to offer customers space-saving, standardized solutions that meet all of their requirements (in every power class, with and without integrated mask filtering, and with backup circuits). “Space-saving” means that, for example, a combiner for 10 low-output transmitters fits inside a single 19” rack, and the high-output combiners only take up half a square meter of space for each transmitter. “Standardized” means that combiners for a wide range of applications (widely spaced or adjacent channels, with or without mask filtering) come in standardized racks and can be quickly and easily exchanged if channels are subsequently replaced or added to. Since all SPINNER combiner systems are completely assembled, tuned, and tested in the factory, they are quick and easy to set up and take live at the station.

In many cases, this makes it possible to avoid costly special designs when space is limited. As far back as 2007, more than 50 TV stations in Europe were retrofitted with the SPINNER CCS system. Besides requiring less space, the CCS system has the advantage of making it possible to use bypass patch panels to minimize the need to take transmitters offline. This is a very important aspect, since when a multiplexed digital television (DTV) channel stops broadcasting four or more TV subchannels can be interrupted. If it’s necessary to temporarily switch off a combiner block, e.g. to change a frequency, the signal can be fed to the combiner’s broadband input instead and continue being broadcast.

Since the SPINNER U-links allow switchovers in a matter of minutes, it only takes two brief nighttime interruptions to implement a frequency change

SPINNER developed the modular CCS system for combiners and patch panels in order to make it possible to implement combining, mask filtering, and a large number of switchover functions in a minimum of space.

By 2010, more than 100 transmitting stations in Europe and Asia had already been equipped with SPINNER CCS combiners, which were easy for local companies to install and take live. The CCS patch panels have already proved their worth for multiple channel changes. Many customers are so satisfied that they are now ordering our CCS combiners for their entire transmission networks.

For planning, installation, operation, and future expansions, the SPINNER CCS system offers network operators enormous benefits that should definitely be taken into account when comparing with competing products.
