Abstract

Payment-based audiovisual playback system characterized by comprising a microprocessor unit, primarily including storage means for storing inter alia in digital form the visual and sound information to be used, and associated, through a number of interfaces, with display means for sound playback which provide a multimedia environment. The unit is controlled by a multitask operating system including a library of integrated tools and services in the storage means. The system is also associated, through an interface, with a telecommunications modem and is connectable to an audiovisual information distribution network by a telecommunications modem and telecommunications links, the telecommunications functions also being managed by the multitask operating system.

Claims

1-10. -10. (canceled)

11. A jukebox, operable to at least play songs selected by a user, comprising:

a touch-screen display, operable to receive touch-based input from a user;

a communications system, connectable to a central server for distribution of at least songs;

a local memory, maintaining at least a database of songs stored on the local memory;

a multi-task operating system, the operating system being arranged to associate a task with respective peripherals and assigning a first priority level to a display task and a second priority level to an audio task.

12. The jukebox of claim 11, further including a system operating status file stored on the local memory, containing data allowing the system to return to a specified location in case of an interruption caused by a fault.

13. The jukebox of claim 12, wherein the system operating status file includes data relating to the insertion of money.

14. The jukebox of claim 12, wherein the system operating status file includes data relating to addition of a selection to a queue.

15. The jukebox of claim 12, wherein the system operating status file includes data relating to the end of a selection.

16. The jukebox of claim 11, wherein the multi-task operating system includes a library of tools and services integrated in the local memory.

17. The jukebox of claim 11, wherein the multi-task operating system includes a priority resolution module.

18. The jukebox of claim 11, wherein the multi-task operating system includes a scheduling module for filling a storage request queue.

19. The jukebox of claim 11, further including at least two temporary buffers for storing video data and at least two buffers for storing audio data retrieved from the local memory, the temporary buffers that store video data allowing the processing of the information transferred into a display buffer by a display control circuitry from one of the temporary buffers during a video data transfer to the other temporary buffer by the operating system, the temporary buffers that store audio data allowing the processing of the information transferred into a reproduction buffer by an audio control circuitry from one of the temporary buffers during an audio data transfer to the other temporary buffer by the operating system, said temporary buffers being associated with respective status buffers arranged to store state data representing respective activities relating to decompression tasks, said status buffers being provided for the temporary buffers that store video data and for the temporary buffers that store audio data, said respective status buffers capable of being put into an active state if one of the two corresponding temporary buffers is empty, and if each of the corresponding temporary buffers contain data being put into an inactive state.

20. The jukebox of claim 19, further including a scheduling module for the operating system arranged to read said status values and to alternatively feed the video and audio buffers with said data, said scheduling module for performing a test to determine the state of status buffers provided for the temporary buffers that store audio data if status buffers provided for the temporary buffers that store video data are in an inactive state, the audio buffer having a size sufficient for storing an amount of data to avoid any lack of data during an audio operation, when a display task has been triggered.
