  • Method, apparatus and computer program product for service decomposition in IP-broadcast networks
    Patent number: 8700793
    Abstract: 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.

  • 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
    Publication number: 20090219987
    Abstract: 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.
