Optische Übertragungsanordnung mit mehreren Übertragungswegen |
摘要 |
The present invention relates to an arrangement for a multiple light path, which may be used for a wireless optical audio and/or video communication system. Known systems use a direct wireless infrared connection. It has been found that such a connection is not reliable enough. It is the object of this invention to realise a reliable infrared connection between different devices. This is realised by a two path connection. A first path is realised by a wireless connection and a second path is realised by a transmission at least partially through an optical fibre. Furthermore this invention presents a special lens and a special photo light emitting diode for the realisation of the two path infrared connection. The invention can used e.g. for the connection between a television set and a video cassette recorder. <IMAGE> |
