Generation of a customizable TV mosaic

1. A method for the generation of a mosaic comprising a plurality of content-transport streams by a module, said streams being received as separate single streams by the module, said method comprising the following steps, after displaying a screen comprising at least a first area intended for displaying a mosaic and a second area comprising a content identifier list:

detecting a command selecting an identifier from the list coming from a user control interface;

obtaining from the user control interface a movement to be applied to said identifier from its position in the list to a determined location in the first area;

successively modifying the definition of the screen by adding a representation of the selected identifier and moving it into successive respective positions along the applied movement and transmitting the modified screen definition to the display device in order to display the successively modified screen;

modifying the definition of the screen by adding a mosaic element showing the stream representing the content identified by the selected identifier in the first area while said second area comprising said content identifier list is still displayed on the screen;

transmitting the screen definition data to the display device for displaying the modified screen.

2. The method according to claim 1 wherein, the command also indicates a determined location in the first area, the definition of the screen is modified by adding a mosaic element in the first area, showing the stream representing the content identified by the selected identifier at the location indicated.

3. The method according to claim 1 , wherein, among the contents, those authorized for viewing are determined and according to which the identifiers of the list to be displayed in the second area are the determined content identifiers.

4. The method according to claim 1 , wherein, following the detection of at least one command coming from the control interface indicating scrolling in a given direction of the list of identifiers:

the definition of the screen is modified by removing at least one content identifier previously displayed at one end of the list in the second area and by adding at least one content identifier not previously displayed in the list to the other end of the list;

the screen definition data are transmitted to the display device in order to display the modified screen.

5. The method according to claim 1 , said method further comprising the following steps:

detecting a command, coming from the control interface, selecting a mosaic element situated at a first determined location in the first area and indicating a movement from the first location to a second location in the first area;

successively modifying the definition of the screen by moving the selected mosaic element into successive respective positions along the movement indicated; and

transmitting the screen definition data to the display device in order to display the successively modified screen.

6. A computer program to be installed in a module capable of receiving content-transport streams, capable of receiving commands transmitted from a control interface and capable of sending screen definition data to a display device in order to display the thus-defined screen, said program comprising instructions for implementing the steps of a method according to claim 1 during execution of the program by processing means of said module.

7. A module capable of receiving content-transport streams, capable of receiving commands transmitted from a control interface and capable of sending screen definition data to a display device in order to display said screen, said module being suitable for implementing the steps of a method according to claim 1 .

8. A television receiver comprising a module capable of receiving content-transport streams, capable of receiving commands transmitted from a control interface and capable of sending definition data to a display device in order to display said screen, said module being suitable for implementing the steps of a method according to claim 1 .

9. A screen definition data intended for display on a display device, comprising at least a first area intended for the display of a content-transport stream mosaic and a second area comprising a content identifier list, said screen definition data being obtained following the implementation of a method according to claim 1 .
