Abstract: For automatising the translation of spoken language into sign language and manage without human interpreter services, a system is proposed, which includes the following features: a database (1), in which text data of words and syntax of the spoken language as well as sequences of video data with the corresponding meanings in the sign language are stored, and a computer (20), which communicates with a database (10) in order to translate fed text data of a spoken language into corresponding video sequences of the sign language, wherein, further, video sequences of initial hand states for definition of transition positions between individual grammatical structures of the sign language are stored in the database (10) as metadata, which are inserted by the computer (20) between the video sequences of the grammatical structures of the sign language during the translation.

Abstract: To allow for a larger selection of viewpoints for the viewer during the reproduction of 3D image contents, it is proposed to compute the two stereoscopic images from the image signals of recording cameras (101, 102, 103), which record images of an object (1) to be reproduced from different viewpoints of a monoscopic position. The stereoscopic images are computed with an image viewpoint, which correspond to the viewing angle of a hypothetical viewer (400) in the central axis of the monitor screen (304). A change of the actual viewing position with regard to the central axis is signalized to a processing unit (301), which computes the two stereoscopic images with image viewpoints changed accordingly.

Abstract: Disclosed are methods and devices for compressing and decompressing video data streams, according to which the statistical relationship between image symbols and the context assigned thereto is used for compression. Particularly disclosed is a context-sensitive encoding unit in which the image symbols filed in an image storage are assigned to different encoding branches via a context switch, where they are encoded and compressed by a Golomb encoder and a run length encoder.

Abstract: The invention can advantageously be applied to voting, wherein invitations for voting which influence the current program on the television set TV are transmitted to the mobile radio device MS, to quiz events, wherein the user is afforded the possibility of entering his answers to questions posed into the mobile radio device MS, to spontaneous purchases or TV commerce, wherein the user can order articles that are promoted or presented during the current program, to messaging, wherein the possibility of sending specific contents is afforded, e.g. “send this clip to a friend”, to communities, wherein e.g. a chat is made available with respect to a broadcast, and to gaming, e.g. in the context of a prize game, relating directly to a current program. What is advantageous with regard to purchases or orders is, in particular, that an unambiguous identification or authentication of the user is ensured by means of the mobile radio communication network NET_UMTS.

Abstract: A method for transferring data between a first computer and a second computer includes detecting and recording occurrences, which reduce quality and which lead to a deterioration in the quality of the transferred data.

Abstract: According to the disclosure, various service messages, such as multimedia messages, short messages, Email messges, fax messages, “Voice Mail” messages, “Instant Messaging” messages etc., available or provided in a service center, or generated in a terminal are transmitted between the service center and a terminal, without the terminal having to be embodied as a client with relation to the transmission and processing of the service message, whereby the service message is directly or indirectly transmitted from the service center to a server, embodied as message server, preparing the message using an intermediate server and sent from the above in prepared form, for output on a network specific terminal to the terminal and multimedia message content is transmitted in the reverse direction from the terminal to the server which generates multimedia messages from the content and then sends the above directly or indirectly to the service center.

Abstract: To allow an individual picture (1) which comprises picture values (3) grouped together into blocks (2) to be quickly compressed with good picture quality, the picture values (3) are quantized block by block by a quantization factor, with the data volume represented by quantized picture values (3) dropping as the quantization factor rises. After the picture values (3) in a block (2) have been quantized, an actual data volume is determined which corresponds to that data volume represented by the last block (2) quantized which is related to the number of picture values (3) in the last block (2) quantized, and a target data volume is determined which corresponds to that volume of storage space which is available for the picture values (3) still to be quantized and which is related to the number of picture values (3) still to be quantized. If the actual data volume is larger than the target data volume the quantization factor is raised, and vice versa.
