Abstract: The invention relates to a device for receiving audio video data packets and corresponding method. According to said method, said packets received comprising an absolute time stamp showing the display time of said packets, said packets being intended to be displayed after their recording, or to be displayed directly following their reception. The device comprises an interface module with the display intended to respect, among other things, the display time of said packets. The device comprises: means for reformatting said packets intended to be displayed after recording in such a manner that these packets after they have been read are received by the interface module with the display in the same format as said packets intended to be displayed directly following their reception, said means for reformatting said packets modifying at least the time stamp of the packets intended for the recording.

Abstract: The invention concerns a method enabling different software versions addressed to different decoders to be mixed in a common stream. The principle consists in defining a unique data format enabling a decoder to be updated from a stream transporting the binary segments of several software versions of the resident software, said binary segments consisting of segments common to several software versions of the resident software, said binary segments consisting of segments common to several software versions and segments specific to each of the software versions.

Abstract: The invention reduces the time required for automatically searching for channels on a device receiving channels of various widths. The invention proposes a channel detection process which carries out successive passes with frequency spacings corresponding to channels of a specific width. During each pass, only the channels corresponding to the specific width are searched for. The invention also pertains to a multichannel reception device comprising the means required for the operation of the process.

Abstract: A method for forcing a terminal to perform an action, and a corresponding terminal and public table. A system broadcasts a public table comprising code for the action. The terminal receives the table, and extracts and executes the code. In a preferred embodiment, the system is a MPEG system and the terminal a decoder. The MPEG broadcast system inserts code into a conditional access table or a programme map table and broadcasts it. The action is advantageously a reset of the decoder which, when it is switched on again, automatically makes it download the latest version of applicable code, such as the operating system. An advantage is that the system operator can make the decoder perform actions, such as upgrading to a newer software version without user interaction.
