Abstract

Disclosed is an information processing apparatus for switching a first session and a second session in executing processing, the apparatus comprising: storage controlling means which, if a first module belonging to a group is activated in the first session, then stores correspondence between the first session and the group; and activation controlling means which, if a second module belonging to the group is activated in the second session, then stops activation of the second module based on the stored correspondence between the first session and the group.

Claims

1. An information processing apparatus to manage usage of resource modules in multiple sessions, said information processing apparatus comprising:

storage controlling means which, if a first resource module belonging to a given group of resource modules is activated in a first session, then the storage controlling means stores correspondence between said first session and said given group of resource modules; and

activation controlling means which, if a second resource module is requested to be activated, then controls activation of said second resource module based on the stored correspondence between said first session and said given group,

wherein if said second resource module is requested to be activated in said first session and said second resource module belongs to said given group, said activation controlling means activates said second resource module,

wherein if said second resource module is requested to be activated in a second session and said second resource module belongs to said given group, said activation controlling means deactivates said second resource module, and

wherein the first resource module and the second resource module belonging to the given group are activated only within a single session, the first resource module and the second resource module can not be activated across more than one session.

2. An information processing apparatus according to claim 1, wherein, if said first resource module is activated, said storage controlling means stores correspondence between said first session and said given group based on data which are held in said first resource module and are indicative of said given group.

5. An information processing apparatus according to claim 1, wherein

said first resource module belonging to said given group corresponds to a single resource.

6. An information processing apparatus according to claim 1, wherein

said second resource module belonging to said given group corresponds to a program being related to hardware for recording.

3. An information processing method for use with an information processing apparatus to manage usage of resource modules in multiple sessions, said information processing method comprising:

if a first resource module belonging to a given group of resources is activated in said first session, then storing correspondence between said first session and said given group of resources;

if a second resource module belonging to said given group is requested to be activated, then activation of said second resource module based on the stored correspondence between said first session and said given group;

if said second resource module is requested to be activated in said first session and said second resource module belongs to said given group, said second resource module is activated; and

if said second resource module is requested to be activated in a second session and said second resource module belongs to said given group, said second resource module is deactivated,

wherein the first resource module and the second resource module belonging to the given group are activated only within a single session, the first resource module and the second resource module can not be activated across more than one session.

4. A computer readable medium storing a computer program for controlling an information processing apparatus to manage usage of resource modules in multiple sessions, said program causing said information processing apparatus to execute:

if a first resource module belonging to a given group of resources is activated in said first session, then storing correspondence between said first session and said given group of resources;

if a second resource module belonging to said given group is requested to be activated, then activation of said second resource module based on the stored correspondence between said first session and said given group;

if said second resource module is requested to be activated in said first session and said second resource module belongs to said given group, said second resource module is activated; and

if said second resource module is requested to be activated in a second session and said second resource module belongs to said given group, said second resource module is deactivated,

wherein the first resource module and the second resource module belonging to the given group are activated only within a single session, the first resource module and the second resource module can not be activated across more than one session.
