METHOD AND DEVICE FOR FORMING A COMMON DATASTREAM ACCORDING TO THE ATSC STANDARD
First Claim
1. A method for forming a common transport datastream from a plurality of a mobile-digital television signal datastreams and from a common stationary-digital television signal datastream, comprising:
- determining a constant number of data units for each of the plurality of mobile-digital television signal datastreams and the common stationary-digital television signal datastream, each constant number having a constant size in every successive time interval with a constant cycle duration for the transmission of the plurality of mobile-digital television signal datastreams and the common stationary-digital television signal datastream;
determining a data structure for the common transport datastream with successive sequences in each case with a constant number of data units with respectively identical positions for data units of a stationary-digital television signal datastream and identical positions for data units of the mobile-digital television signal datastream, respectively, wherein data units of each of the mobile-digital television signal datastreams are transmitted respectively in associated, identical positions of at least one successive sequence; and
packing individual positions of the data structure of the common transport datastream with data units of the associated plurality of mobile-digital television signal datastreams and common stationary-digital television signal datastream.

Abstract
A method and a device for forming a common transport datastream from several mobile-digital television signal datastreams and a common stationary-digital television signal datastream. A constant number of data units of respectively-constant size in every successive time interval with constant cycle duration for the transmission of every individual datastream is determined. A data structure is specified for the common datastream with successive sequences in each case of a constant number of data units with respectively-identical positions for data units of the stationary-digital television signal and respectively-identical positions for data units of the mobile-digital television signal. Data units of each of the datastreams of the mobile-digital television signal are transmitted in each case in associated, identical positions of at least one successive sequence, and define the individual positions of the data structure of the common datastream with data units of the respectively associated datastreams.

16. A device for forming a common transport datastream from a plurality of mobile-digital television signal datastreams and a common stationary-digital television signal datastream, comprising:
-
a plurality of stationary-digital television coding units configured generate a plurality of stationary-digital television signal datastreams from respective stationary-digital television channels; a plurality of mobile-digital television coding units configured to generate a plurality of mobile-digital television signal datastreams from respective mobile-digital television channels; a first multiplexer configured to generate the common stationary-digital television signal datastream from the plurality of stationary-digital television signal datastreams; and a second multiplexer in communication with the first multiplexer and the plurality of stationary-digital television coding units and the plurality of mobile-digital television coding units and configured to generate the common transport datastream from the plurality of mobile-digital television signal datastreams and the common stationary-digital television signal datastream, wherein one of the plurality of mobile-digital television coding units operates as a superordinate master unit and is connected to the other mobile-digital television coding units operating as subordinate slave units, wherein a data structure for the common transport datastream is formed with successive sequences in each case of a constant number of data units with respectively identical positions for data units of the stationary-digital television signal datastream and identical positions for data units of the respective mobile-digital television signal datastream, and wherein data units of each mobile-digital television signal datastream are transmitted respectively in associated, identical positions from at least one successive sequence. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
