20080320358 | Encoding and Decoding Method, and Encoding and Decoding Devices with a Two-Stage Error Protection Process - An encoding method for a series of data packets transmitted in the framework of a combined streaming and downloading application by a two-stage error protection process and only one unidirectional transmission channel. According to said method, a partial block of successive data packets is protected against at least some of the transmission errors occurring during streaming with the aid of a first error protection process while all data packets are protected against the transmission errors remaining after streaming is completed with the aid of a second error protection process. In a decoding method by which a series of data packets that are encoded according to the encoding method are decoded. Also disclosed is an encoding and decoding device for carrying out the method. | 12-25-2008 |
20090067450 | METHOD AND SYSTEM FOR ENCODING OR DECODING A SEQUENCE OF DIGITAL DATA - A method is provided for encoding and decoding a sequence of digital data, according to which a portion of the sequence of digital data corresponds to a data block that includes several data packets, at least two data packets per data block containing an identifier. The position of the data packet within the corresponding data block can be determined based on the identifier, and the data is encoded or decoded by taking into account the identifier. | 03-12-2009 |
20090144602 | Method and System for Encoding or Decoding a Sequence of Digital Data - A method is provided for encoding and decoding a sequence of digital data, according to which a portion of the sequence of digital data corresponds to a data block that includes several data packets, at least two data packets per data block containing an identifier. The position of the data packet within the corresponding data block can be determined based on the identifier, and the data is encoded or decoded by taking into account the identifier. | 06-04-2009 |
20090219987 | Method and Device for Generating a Marked Data Flow, Method and Device for Inserting a Watermark Into a Marked Data Flow, and Marked Data Flow - A method generates a marked data flow from an encoded data flow; at least one first data flow section of the encoded data flow is marked as a marked data flow section; and the marking of the marked data flow section indicates that the marked data flow section is suitable to be mixed with a watermark. A method inserts watermarks into the marked data flow, and devices generate the marked data flow and insert watermarks into the marked data flow. | 09-03-2009 |
20110131474 | ENCODING AND DECODING METHOD, AND ENCODING AND DECODING DEVICES WITH A TWO-STAGE ERROR PROTECTION PROCESS - An encoding method and device are provided for a series of data packets transmitted in the framework of a combined streaming and downloading application by a two-stage error protection process and only one unidirectional transmission channel. A partial block of successive data packets is protected against some transmission errors occurring during streaming with the aid of a first error protection process while all data packets are protected against the transmission errors that can remain after streaming is completed with the aid of a second error protection process. In a decoding process, a series of data packets that are encoded according to the encoding are decoded. | 06-02-2011 |
20120047278 | Method, Apparatus and Computer Program Product for Service Decomposition in IP-Broadcast Networks - In a method, an apparatus and a computer program product for service decomposition in IP-broadcast networks, a full service bundle is detected within a first transport stream protocol having a plurality of broadcast packets corresponding to respective broadcast services. The respective service identifiers of the plurality of broadcast packets are evaluated, and the full service bundle is decomposed to create a plurality of decomposed broadcast packets on the basis of the service identifiers. For at least one same service identifier the corresponding plurality of decomposed broadcast packets is sent with the first transport stream protocol as a main service bundle, and for at least one remaining same service identifier the corresponding plurality of decomposed broadcast packets is sent with a second transport stream protocol as a sub service bundle. The second transport stream protocol contains synchronization information of the first transport stream protocol. | 02-23-2012 |
