20100106802 | APPARATUS AND METHOD FOR GENERATING A DATA STREAM AND APPARATUS AND METHOD FOR READING A DATA STREAM - When generating a data stream, text data, an escape-start-sequence, a first number of data units, an escape-continuation-sequence and a second number of data units are entered into a data stream. A base decoder displays only the text data and skips the data units referenced by the escape-start-sequence and the escape-continuation-sequence, while an extension decoder reads those data units and processes them together. | 04-29-2010 |
20110093930 | Concept of Efficiently Distributing Access Authorization Information - A device for controlling a service access authorization for a user device with regard to an access-restricted service includes a service access authorization provider, the service access authorization provider being configured to set a period of time in which the service access authorization is valid, responsive to an authorization message provided with a service-dependent user identifier, and the service access authorization provider being configured to disable an authorization allowing the service access authorization to be extended or reactivated using the previous service-dependent user identifier when at least a predetermined duration has passed since an end of a last authorization time interval for which a service access authorization was determined by the device. | 04-21-2011 |
20120124095 | Text-Based Information Transmission - The navigation overhead and/or the content managing/updating overhead is reduced by providing link objects with condition data being associated with the link items of the link objects so that, depending on a check as to whether the condition data is fulfilled or not, an automatic handling of a link object may be performed. For example, the automatic handling may have an automatic appointing an object ID referred to by a link item of the link object that has condition data associated therewith which is fulfilled, as a newly-selected object ID. | 05-17-2012 |
20120185526 | Transmission Scheme for Text-Based Information - A text-based information transmission is made complying with a greater number of transport-layer systems by performing the fragmentation and de-fragmentation of the information object at the application-layer side rather than at transport-layer domain. By this manner, the text-based information service is not restricted to transport-layer systems accommodating the maximum size of the information objects. Rather, it is possible to adjust the fragmentation size of the fragments into which the information objects are fragmented to the maximum transport packet content section size offered by the transport layer within the application layer. The fragment size may even vary in a time-varying manner responsive to instructions from the transport layer posed onto the transport layer in consequence of time-varying transmission channel characteristics, for example. | 07-19-2012 |

20130152121 | TRANSPORT-STREAM PROVIDER, DAB SIGNAL PROVIDER, TRANSPORT STREAM ANALYZER, DAB RECEIVER, METHOD, COMPUTER PROGRAM, AND TRANSPORT STREAM SIGNAL - A transport stream provider for providing a plurality of transport stream packets describing digital media information is configured to provide a transport stream packet of a first packet type including a program association table and key information for decrypting encrypted media information. The program association table contains an association between a program No. and a packet type identifier of a further transport stream packet of a second packet type. The transport stream provider is configured to provide a transport stream packet of the second packet type in such a manner that the transport stream packet of the second packet type contains a reference to packet type identifiers of transport stream payload data packets which describe contents of different content types of the digital media information. | 06-13-2013 |
