Abstract

A command and control architecture for a compressed digital television broadcast studio. The architecture includes provisions for session management, real-time control of studio activities, the use of proxy objects to establish communications with objects not providing a high level of control, control of studio filter devices and stream management. The invention includes an object architecture particularly suited to a digital studio.

Claims

1. A command and control architecture for a digital studio having a plurality of studio components including studio components associated with respective objects, said objects providing representation of one or more functions of said respective studio components, said command and control architecture comprising:

means for locating a desired studio component by locating an object associated with said desired studio component;

means, coupled to said locating means, for acquiring control of said desired studio component by controlling said object associated with said desired studio component,

means, coupled to said acquiring means, for specifying an interconnection to said desired studio component to establish a stream to said desired studio component; and

means, coupled to said specifying means, for controlling said stream by controlling an object associated with said stream.

2. The command and control architecture of claim 1, wherein said object associated with said stream is an object corresponding to a state of an underlying image sequence.

3. The command and control architecture of claim 2, wherein said object associated with said stream is for manipulating selectively said underlying image sequence.

4. The command and control architecture of claim 3, wherein said object associated with said stream is manipulated for playing said underlying image sequence.

5. The command and control architecture of claim 3, wherein said object associated with said stream is manipulated for stopping a display of said underlying image sequence.

6. The command and control architecture of claim 3, wherein said object associated with said stream is manipulated for pausing a display of said underlying image sequence.

7. The command and control architecture of claim 3, wherein said object associated with said stream is manipulated for rewinding said underlying image sequence.

8. The command and control architecture of claim 3, wherein said object associated with said stream is manipulated for forwarding said underlying image sequence.

9. A method for managing digital data for a digital studio having a plurality of studio components including studio components associated with respective objects, said objects providing representation of one or more functions of said respective studio components, said method comprising the steps of:

(a) locating a desired studio component by locating an object associated with said desired studio component;

(b) acquiring control of said desired studio component by controlling said object associated with said desired studio component;

(c) specifying an interconnection to said desired studio component to establish a stream to said desired studio component; and

(d) controlling said stream by controlling an object associated with said stream.

10. The method of claim 9, wherein said controlling step (d) controls said object associated with said stream that corresponds to a state of an underlying image sequence.

11. The method of claim 10, wherein said controlling step (d) controls said object associated with said stream for manipulating selectively said underlying image sequence.

12. The method of claim 11, wherein said controlling step (d) controls said object associated with said stream for playing said underlying image sequence.

13. The method of claim 11, wherein said controlling step (d) controls said object associated with said stream for stopping a display of said underlying image sequence.

14. The method of claim 11, wherein said controlling step (d) controls said object associated with said stream for pausing a display of said underlying image sequence.

15. The method of claim 11, wherein said controlling step (d) controls said object associated with said stream for rewinding said underlying image sequence.

16. The method of claim 11, wherein said controlling step (d) controls said object associated with said stream for forwarding said underlying image sequence.

17. A computer-readable medium having stored thereon a plurality of instructions, the plurality of instructions including instructions which, when executed by a processor, cause the processor to perform the steps comprising of:

(a) locating a desired studio component by locating an object associated with said desired studio component;

(b) acquiring control of said desired studio component by controlling said object associated with said desired studio component;

(c) specifying an interconnection to said desired studio component to establish a stream to said desired studio component; and

(d) controlling said stream by controlling an object associated with said stream.

18. The computer-readable medium of claim 17, wherein said controlling step (d) controls said object associated with said stream that corresponds to a state of an underlying image sequence.

19. The computer-readable medium of claim 18, wherein said controlling step (d) controls said object associated with said stream for manipulating selectively said underlying image sequence.

20. The computer-readable medium of claim 19, wherein said controlling step (d) controls said object associated with said stream for playing said underlying image sequence.
