Embodiment Construction

[0023] Figure 1A Schematic illustration of frequency spectrum used for signal distribution; specifically, frequency bands up to 40MHz are occupied by cable television (CATV) return channels for communication exchange between subscribers and service providers; 47-68MHz and 174-230MHz The frequency bands include TV channels belonging to the first VHF (Very High Frequency) band and the third VHF band; UHF (Ultra High Frequency) TV channels are located at 470-862 MHz. The two frequency bands 110-174MHz and 230-445mHz are used for the distribution of CATV channels and converted satellite channels. The 230-445mHz frequency band is also known as the extended S-band. The VHF frequency band is subdivided into 7MHz wide channels, while CATV and UHF channels are 8MHz wide, such as Figure 1C shown schematically. Figure 1B A particular use of spectrum in the range 41-46.5 MHz is schematically shown, which will be described below.

Abstract

The present industrial invention concerns a system for the distribution in a condominium and / or community environment of a plurality of television signals, and / or audio signals, and / or digital audio and / or video signals transmitted with different standards. According to the invention, one or more digital signals can be received by a single user of the system by means of a frequency conversion into a predetermined channel, which can be accessed by said user only. The digital signal being present in said channel always has the same modulation and can be selected by said user through control means which send a control signal to selection means.

Description

technical field [0001] The industrial invention relates to the distribution system of multiple television signals and / or audio signals, especially the distribution system of video and audio signals of different standards in the environment of apartment buildings and / or residential areas. "Apartment building" refers to a group of apartment units, and "settlement" refers to a group of one or several buildings. Background technique [0002] The development of digital technology, especially signal compression technology, has led to digital television via terrestrial, cable and satellite transmission. Digital television offers wider program availability (for example, the fact that 4 to 6 digital programs can be allocated within the frequency band occupied by an analogue channel), and the implementation of new so-called man-machine conversational services (such as the so-called Benefits of VOD (Video On Demand) or NVOD (Near Video On Demand). [0003] Clearly, to receive these n...
