Abstract:
1. Device for recording coded digital audiovisual data being received from a digital video broadcast event via video signals in which information about the total amount of data or the remaining amount of data of the coded digital audiovisual data of the program contributions is not received with the coded digital audiovisual data, which comprises: a mass storage medium for storing at least one portion of coded audiovisual program data, said portion including at least one of audio data and video data from a program contribution, and said portion having a varying data rate, a device for continuous determination of an instantaneous data rate, to determine a weighted mean data rate for the respective portion of the program data and to determine, based on the weighted mean data rate and based on program information about the program contribution, if sufficient storage capacity is present in a corresponding portion of the mass storage medium for a complete recording of the portion of coded audiovisual program data of the program contribution, the device further comprising: a demultiplexer for separation of the portion of coded digital audiovisual program data with a varying data rate, which is a part of a program contribution, from a transport data stream, a program information decoder connected to the demultiplexer for obtaining the program information about the program contribution, wherein the program information includes at least one of a genre and a sender, and also includes a starting time and stopping time for the portion of the program contribution, and wherein said program information does not include information about the total amount of data or the remaining amount of data of the coded digital audiovisual data of the program contributions, and another storage area provided in the mass storage medium, which is provided for storing the instantaneous data rate determined in the device for later access in determination of the weighted mean data rate for respective portions of the program contribution; and wherein the weighted mean data rate is a nonlinear function of values for the instantaneous data rate and wherein the weighted mean data rate is further related to at least one of: a) a plurality of program contributions of each genre and b) an evaluation of the transport data stream of a sender.
