Abstract: Thematic map preparation method and apparatus, a storage medium and an electronic device are provided. The method includes: preparing a map style master based on an aimed application field; generating metadata information corresponding to the map style master, wherein the metadata information includes a mapping relationship between each of the geographical units in the map style master and the initial color identification corresponding thereto, and the metadata information further includes location information about the legend in the map style master; processing original input data, and acquiring an attribute color identification of each geographical unit in the original input data; and replacing the initial color identification corresponding to each of the geographical units in the map style master with the attribute color identification, and updating the legend, so as to obtain a thematic map of the original input data when aimed at the application field.

Abstract: A method of transcoding a content stored on a first server (OS) is provided. The first server (OS) is arranged within an UPnP network comprising at least one first server (OS), at least one UPnP renderer (UR) and at least one UPnP control point (CP). The content directory services (CDS) of the at least one first server (OS) are browsed to determine the available content and the available encodings of the content. The rendering capabilities of the at least one renderer (UR) are determined. The rendering capabilities of the at least one renderer (UR) are compared with the available content and the available encoding of the content according to the content directory service of the at least one server (OS). The content directory service (CDS) of the at least one server (OS) is updated.
