Method and apparatus providing scalability for channel change requests in a switched digital video system
First Claim
1. A method of providing channel change requests in a Switched Digital Video (SDV) system, the method comprising:
- receiving a request for a channel change;
determining if a channel requested by said request for a channel change is being provided to said settop box;
when said channel requested by said request for a channel change is currently being provided to said settop box then buffering said request for a channel change for transmission of said request for a channel change at a later time; and
when said channel requested by said request for a channel change is not being provided to said settop box then immediately sending said request for a channel change to an SDV server in communication with said settop box.

Abstract
A method, apparatus and computer program product for providing scalability for channel change requests in a Switched Digital Video system is presented. A request for a channel change is received. A determination is made regarding whether a channel requested by the request for a channel change is currently being provided to the settop box. When the channel requested by the request for a channel change is being provided to the settop box then the request for a channel change is buffered for transmission at a later time. When the channel requested by the request for a channel change is not being provided to the settop box then the request for a channel change is immediately sent to an SDV server in communication with the settop box.

7. A settop box comprising:
-
a memory; a processor; a communications interface; an interconnection mechanism coupling the memory, the processor and the communications interface; and wherein the memory is encoded with an application providing channel change requests in a Switched Digital Video (SDV) system, that when performed on the processor, provides a process for processing information, the process causing the settop box to perform the operations of; receiving a request for a channel change; determining if a channel requested by said request for a channel change is currently being provided to said settop box; when said channel requested by said request for a channel change is being provided to said settop box then buffering said request for a channel change for transmission of said request for a channel change at a later time; and when said channel requested by said request for a channel change is not being provided to said settop box then immediately sending said request for a channel change to an SDV server in communication with said settop box. - View Dependent Claims (8, 9, 10, 11, 12)

13. A computer readable medium having computer readable code thereon for providing channel change requests in a Switched Digital Video (SDV) system, the medium comprising:
-
instructions for receiving a request for a channel change; instructions for determining if a channel requested by said request for a channel change is currently being provided to said settop box; instructions for when said channel requested by said request for a channel change is being provided to said settop box then buffering said request for a channel change for transmission of said request for a channel change at a later time; and instructions for when said channel requested by said request for a channel change is not being provided to said settop box then immediately sending said request for a channel change to an SDV server in communication with said settop box. - View Dependent Claims (14, 15, 16, 17, 18)

19. A Switched Digital Video (SDV) system comprising:
-
an SDV server; at least one settop box, each of said at least one settop box in communication with said SDV server; and wherein at least one of said settop box is capable of receiving a request for a channel change from a user, determining if a channel requested by said request for a channel change is currently being provided to said settop box, when said channel requested by said request for a channel change is being provided to said settop box then buffering said request for a channel change for transmission of said request for a channel change at a later time to said SDV server and transmitting said request for a channel change at a later time, and when said channel requested by said request for a channel change is not being provided to said settop box then immediately sending said request for a channel change to said SDV server. - View Dependent Claims (20)
