-* '''Camera Capture:''' As previously explained in other sections of this Wiki, Camera Capture represents the module in charge of managing the reception and processing of the information data coming from the cameras used by the application. To fulfill this purpose, Camera Capture interacts with entities called Medias, which encapsulate within its structure, the type of camera used, the protocol in which the data is received, and provides the necessary operations to manipulate the flow of information.
+* '''Camera Capture:''' As previously explained in other sections of this Wiki, Camera Capture represents the module in charge of managing the reception and processing of the information data coming from the cameras used by the application. To fulfill this purpose, Camera Capture interacts with entities called Medias, which encapsulate within its structure, the type of camera used, the protocol in which the data is received, and provides the necessary operations to manipulate the flow of information. Camera Capture is in charge of creating the respective Media instances. For this, it uses a Media Factory, and a Media Descriptor, so that through the description entered into the module, the factory can be used to build the new Media of the system. Of course, the tasks of Camera Capture also include managing the processes of starting and stopping the flow of information. In this way, it could be said that Camera Capture is the entity in charge of manipulating the instantiation, deletion, and regular operation of the Media entities.
-* '''Media Factory:''' This class simply represents a Data Transfer Object (DTO), which will contain the information parsed by the custom Inference Parser. The idea is that the rest of the system modules can share this DTO to transmit the information obtained from the inference process so that everyone can interpret it regardless of the context of the application with which they are working. It is the responsibility of the Inference Parser to produce a new Inference Info after parsing the information received.
+* '''Media Factory:''' Each custom implementation of a Media type must have an associated module in charge of its creation. As shown in the class diagram, a Factory Pattern is used for the design of this part of the system, where a Factory Interface is provided, which indicates the minimum operations that this module must include. The Factory will receive a Media descriptor as a parameter, which indicates the information required to instantiate a new Media type. The Camera Capture module will be in charge of using the functionalities of the Factory for the construction of the Media.
