摘要: A converter circuit is specified for voltage maintenance in an electrical AC supply network (1), with the electrical AC supply network (1) having an associated voltage source (UR; US; UT) for each phase (R; S; T) for supplying an electrical load (2), with the converter circuit having a respective inverter (3) for each phase (R; S; T), which inverter (3) is connected on the DC side via an energy-storage capacitor (4) to a supply device (5). On the AC side, each inverter (3) is connected in series between the associated voltage source (UR; US; UT) and the electrical load (2) in the respective phase (R; S; T), and in that, on the AC side, the supply device (5) is connected to at least two phases (R; S; T) between the associated voltage sources (UR; US; UT) and the respective inverters (3).

摘要: A method for providing an encoded video application (3D APP; 2DAPP) from a server (SERVER) to a respective client (CLIENT1, . . . , CLIENTN) user via a communications link, comprises steps of updating scenes pertaining to said video application (3DAPP; 2DAPP) at said server (SERVER), deriving therefrom a respective video stream (2Dvideo 1, . . . 2DvideoN) comprising a succession of respective 2D user-related viewpoints for said respective client (CLIENT1, . . . , CLIENTN), calculating at least one respective compression related parameter (ep2D—1, . . . , ep2D_N) from application object vertex information extracted from a subset of successive ones of said scenes pertaining to said video application (3DAPP; 2DAPP) at said server, using said respective compression related parameter (ep2D—1, . . . , ep2D_N) during subsequent encoding of said respective video stream (2D-video1, . . . 2DvideoN), for thereby generating a respective encoded video stream (encoded2D video—1, . . . , encoded2DvideoN) for provision to said respective client user (CLIENT1, . . . , CLIENTN). A server adapted to perform this method is disclosed as well
