## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention describes a method for managing digital files, such as, for example, applications developed for digital TV, in a digital TV receiver apparatus with support for the execution of said digital files, as well as a manager of said digital files.
Particularly, the manager has a visual interface that enables the user to identify which applications are present in the digital TV receiver apparatus, install and/or uninstall applications, in addition to providing quick access to certain applications.
2. Prior Art
A digital TV receiver apparatus is a device capable of receiving and decoding the digital signals sent by broadcasters for presentation on a monitor. Said apparatus can be fixed (integrated to the TV set or not), portable or mobile.
Several applications already exist and are being developed for said receiver apparatus, and include, for example, solutions for e-business, program guides, access to stock exchange trading figures, weather forecast, games, surveys and many others.
In the model proposed for Brazilian digital TV, said applications are sent independently by broadcasters and received by digital receiver apparatus with support for interactivity, which are responsible for executing them. In this model, when we change channels, the current application is interrupted, and not saved, so that the application of another broadcaster can be loaded.
As the possibilities for interaction increase, along with the access speeds and the storage capacity of the digital TV receiver apparatus, new opportunities for the development of these applications appear.
In the proposed scenario, applications can be developed so that they co-exist on the digital TV receiver apparatus co-operatively in such a way that the user has a positive and satisfactory experience when using them. Furthermore, since resources are limited in digital TV receiver apparatus, there is a need to manage the applications, providing a streamlined control of said resources.
With this in mind, document WO 00/30346 describes a method for managing a receiver apparatus designed to manage the hardware components, such as sound and image components, memory, among others.
The present invention differs from this document by not being designed to manage the hardware, but rather the digital content that can be executed by the receiver apparatus.
The literature search revealed no documents revealing or suggesting the teachings of the present invention, to the extent that the solution proposed herein is novel and inventive in comparison with the state of the art.

Example 1
The applications manager, called “Sticker Center”, is built in by the manufacturer to the memory of the digital TV receptor, and is called by the user by a button (dedicated or not) on the remote control 420. When called, the manager appears above a background that can be, but is not limited to, a video 202 being aired by the broadcaster currently tuned 400, a static or animated image file, or a video file built into the receptor.
The essential function of the applications manager is to manage and execute different types of applications installed in the receptor 428, 524, 702.
The first types of applications controlled by the manager are the utility applications installed by the user in the receptor 122, 314, and as shown in FIG. 5A (the “stickers”).
The second types of applications controlled by the manager are the applications previously installed in the receptor by the manufacturer 124, 304 (the “prime stickers”).
The third type of applications controlled by the manager are the applications that are being transmitted by the digital signal of the broadcaster currently tuned 400, and that will work only for as long as this broadcaster is tuned in (broadcaster stickers) 126. These applications will be identified 402, received 406 and installed 408 by the manager 128. If the broadcaster so wishes 410, these applications may be uninstalled 412 from the receptor by a specific command sent via digital TV signal to the manager. As shown in FIG. 4A.
The icons that call these three types of applications can be seen in the applications manager, and can be displayed on the TV screen in an area for quick access (main menu) 206 or on a specific user menu called “My stickers” 302, 304, 314.
The display for fast access (main menu) 206 can be shown vertically or horizontally. The limit on the screen will be 1 access icon to the user menu (My stickers) 204, 500 and X icons for applications compatible with the manager that are being transmitted by the signal of the broadcaster currently tuned (broadcaster stickers) 208.
When the user uses the arrows of the remote control to move the navigation focus through the fast access menu (main menu) to the desired icon 208, 424 and press the confirmation key (OK), the corresponding application (broadcaster sticker) will be executed by the receptor 428.
When the user uses the arrows of the remote control to move the navigation focus through the fast access menu (main menu) to the access the icon for the user menu (My stickers) and presses the confirmation key (OK) 500, the user menu will appear 520.
When the Sticker Center is accessed, the “broadcaster stickers” are automatically downloaded 406 by the digital signal from the TV broadcaster currently tuned 400 in and are installed 408 in the digital TV receptor in an area dedicated to installing these applications 126, as shown in FIG. 4A.
The broadcaster may uninstall these applications automatically by sending the respective digital TV command signal 410, 412, for example, at the end of a certain program.
In relation to the display for the user menu (My Stickers) the total limit of stickers displayed 520, 304, 314 will be determined by the quantity of applications installed which, in turn, is limited by the quantity of memory 132 available in the receptor. These sticker icons 304, 314 can be chosen and organized by the user by way of a configuration interface.
When the user uses the arrows of the remote control to move the navigation focus to the desired icon 304, 314 and presses the confirmation key (OK) 522, the corresponding utility application (Sticker) will be executed by the receptor 524, 702.
During the process of navigating through the interface of the user menu, descriptive information on the “stickers” can be seen in the descriptive area 312.
The applications manager enables the user's accounts to be managed 106, and creating at least one account in the manager is an important step requested upon first access to the system.
Once the first account is created, it is possible to create new accounts or edit existing accounts by just accessing the accounts management area by way of the respective icon 306.
Each account stores information on a given user 110, such as the configurations of the manager, of the menu, data of each application, among others.
The sub-system “Sticker Shop” is accessible from the “Sticker Center” 308, 504. This sub-system is stored in a dedicated server 130, which will be accessed by way of the digital receptor through the interactivity channel 120. It will be possible to locate, see details and make a free or paid transfer of utility applications (“stickers”) in the “Sticker Shop” 506. The “stickers” can be downloaded via the interactivity channel 508 and executed through the digital receiver 512, 524.
The number of applications that can be received and installed is limited by the memory of the receiver 132.
