| 20090162688 | METHOD OF MAKING A HYBRID STRUCTURE, AND HYBRID STRUCTURE - In a method of making a hybrid structure, at least one support body is fixed in a tube component which is then placed in an injection molding tool. An injection-molded part is injection-molded to an outer surface of the tube component in an area of the support body. As a result, the tube component is inwardly deformed, when regions adjacent to the support body are exposed to an injection pressure, and forms indentations for engagement of the injection-molded part. | 06-25-2009 |

| 20100011390 | Method and Configuration for Storing and Playing Back TV Transmissions - An improved method and configuration for operating a network containing a personal video recorder server having measures for receiving several digitally encoded TV channels, for feeding several terminals and for recording storable TV programs. The terminals have measures for selecting storable TV programs and measures for transmitting the choice to the PVR server. The configuration contains a first database in which the index of TV programs stored by the PVR in response to the selection produced by the terminal is recorded. The first database controls authorization or refusal to play back the stored programs on the terminal. A second database stores, for the first terminal, the other terminals authorized to play back the TV programs selected by the user of the first terminal or all TV programs associated therewith by the first data base index. Terminals that are not contained in the second database are not authorized. | 01-14-2010 |
| 20100023976 | Method and Configuration for Storing and Playing Back TV Transmissions - A method and a configuration for storing and playing back TV transmissions, in particular an improved method and configuration for operating a network PVR, include a PVR server for receiving digitally encoded TV channels. Terminals select TV transmissions to be stored and transmit the selection to the PVR server. The PVR server records the TV transmissions to be stored, wherein a small part of data items to be stored during recording is transmitted to the memory of the selecting terminal and a main part of the data items to be stored is recorded in a mass storage device coupled to the PVR server. The parts of the recording stored in the memory of the selecting terminal and in the mass storage device are combined in such a way that they can be played back through the use of the selecting terminal, either by the selecting terminal or by the PVR server. | 01-28-2010 |
