DESCRIPTION

"INTERACTIVE AND SMART DIGITAL MULTIMEDIA DISPLAY SYSTEM

AND METHOD"

Technical Field of the invention

The present invention refers to an advanced solution for managing interactive digital signage and communication, liable to control in real-time, through application contents, systems and external applications (3rd party applications) , variable multimedia contents, advanced systems of automation and mechatronics, among other sources with specific protocols.

Summary of the invention

The present invention refers to an advanced solution for digital signage, used for communication of high impact, which allows the user, via commutation equipment comprising hardware devices, such as multimedia devices, and mobile computing devices, and a platform for integrating contents, to allow the connection without limits for the various access points of information.

The present invention is thus useful to allow anyone, such as a non-trained authorized user, to publish contents on a TV or other multimedia device, without the need to have specific knowledge of programming, without the need of dedicated physical infrastructure, without local access, only with an internet access and a mobile computing device smaller than a credit card, this device being 100% passive and very silent, needing only an energy source up to 5V to guaranty the continuous passage and display of the desired contents, even when the internet access is temporarily interrupted.

Background of the invention

US20110124318 discloses an advanced advertising system/method that is especially useful with billboard advertisements, physical location of business, TV ads, radio ads and/or local services that are available within a specified zone/area or specific vicinity. More specifically the invention relates to either a system/method that allows a user to easily obtain information via GPS location and/or an identifier code from an advertisement or the like via a Smartphone/Smart device or any other type of interactive apparatus. This system comprises (i) a Smartphone/Smart- device, (ii) a user, (iii) a service provider, (iv) a GPS mapping program database, (v) a web portal/interface, (vi) a vendor, (vii) an advertisement, the system includes options of choice (A) , (B) , (C) or (D) and said user chooses option (A), the method comprising the steps of:

(a) activating Smartphone/Smart-device;

(b) activating software of the system;

(c) activating an icon of choice and;

(d) activating or saving an icon associated with an advertisement. This patent application claims to address problems such as non-effective advertising methods, the need for use of expensive equipment and also complicated to implement by non-experienced users, non-cost-effective methods of advertising, publishing and signage. The present invention not only provides an improved solution to these problems but also addresses additional problems, such as the need for bulky equipment, the need to display contents in all kinds of multimedia devices, the need for updating and publishing multimedia contents in real-time and also periodically verifying the rights for transmission of the multimedia contents, guarantying that the display of the multimedia contents is not allowed when the location, the rights of transmission and other safety parameters are different from those previously set.

WO2008028696 discloses a device for publishing multimedia contents by rendering them accessibility to the public and comprises an electronic processor connected to publication units for multimedia contents. The electronic processor carries stored in its memory the multimedia contents to be published, and information relative to the dates and times of publication. The processor supports control software for controlling the publication of the multimedia contents via the publication unit on the set dates and times; first communication software for downloading online the information relative to the dates and times of publication; and second communication software for downloading online said multimedia contents to be published and/or their updating. The method enables publication of the multimedia contents via the publication unit on the set dates and times to be automatically commanded. The present invention allows for the possibility of real-time updating and publishing of contents, without the need of preprogramming. Furthermore, the present invention comprises an operational architecture and method more efficient because together they assure the updating of multimedia contents on the mobile computing devices, which would have a role partly similar to the publication units, and also the successful verification of the rights for transmission, even if an internet connection is not available, due to a proactive cache on the mobile computing devices.

General Description of the Invention

The flexibility of the solution from the present invention, also referred to as "Point&Click", has no need for previous programming, allows the user to have access from all around the world, using any hardware device, such as a multimedia display device, with any type of contents (particularly operating third-party applications such as PowerPoint or native applications) . It can be applied in TVs, monitors and screens, multimedia kiosks or any other type of display equipment or device. It can also be used internally within the organizations, to provide information, enabling the integration of advanced monitoring and management control with a 100% cloud implemented solution, "infinitely" scalable and with minimum technical requirements in terms of user knowledge and training, being necessary only to make available, e.g., a tv and an internet connection, to be able to control, remotely, and after installation, all the mobile computing devices and the hardware devices connected thereto, without the need to establish a physical connection to these devices in order to perform OS, antivirus, codecs updates, among others. The present invention uses a database structure with the ability to manage each one of the devices integrating the solution, according to the location of the TV or display screen, according to the desired contents, etc.

The incorporated proactive cache system, which is one of the main advantages of the present invention, ensures the passage of contents even when there is no internet connection, automatically updating the multimedia contents as soon as the connection is restored.

Multimedia refers to contents that use a combination of different content forms. This contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material. Multimedia includes a combination of text, audio, still images, animation, video, or interactivity content forms. Multimedia is usually recorded and played, displayed, or accessed by information content processing devices, such as computerized and electronic devices, but can also be part of a live performance.

Multimedia devices are electronic media devices used to store and experience multimedia content. Multimedia is distinguished from mixed media in fine art; by including audio, for example, it has a broader scope. The term "rich media" is synonymous for interactive multimedia. Hypermedia can be considered one particular multimedia application.

A hardware device according to the present invention is any device or equipment that sends data or instructions into a computer or a device to which a computer sends data or instructions to. Examples of hardware input devices are a mouse, keyboard, voice recognition system, digital camera, barcode reader, optical readers, magnetic readers, sensors, mechanical and electronic receptors, RFID reader, smart card reader, touch-sensitive screen, graphics tablet, scanners, check digits and others. Examples of hardware output devices are visual display units, such as cathode- ray tube, flat screen (LCD) or a plasma screen, sound output, electronic paper, printers and others. A mobile computing device is any device comprising mobile components, such as mobile hardware and software.

Mobile computing devices are portable devices capable of operating, executing and providing services and applications like a typical computing device.

In a preferred embodiment of the present invention, a mobile computing device preferably comprises the following specifications (Table 1) :

Where there is a screen, regardless of location or available infrastructure, the integrated solution, the mobile computing device with the developed solution Smart . Signage®, allows any authorized user to control, online and on-time, all the broadcasted and available contents. The present invention is applicable for any business using high impact or other type of communication as a privileged channel to target customers and potential customers, or having the need to inform, manage flows for contents passage and customer service lines or creating "gaming" initiatives to improve sales processes and reducing costs.

An SSID (Service Set Identifier) is the name of a wireless local area network (WLAN) . All wireless devices on a WLAN must employ the same SSID in order to communicate with each other. The SSID on wireless clients can be set either manually, by entering the SSID into the client network settings, or automatically, by leaving the SSID unspecified or blank. A network administrator often uses a public SSID, that is set on the access point and broadcast to all wireless devices in range. Some newer wireless access points disable the automatic SSID broadcast feature in an attempt to improve network security.

A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model.

A wireless Access Point (AP) is a device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards. The AP usually connects to a router (via a wired network) as a standalone device, but it can also be an integral component of the router itself.

An Ethernet hub, active hub, network hub, repeater hub, multiport repeater or hub is a device for connecting multiple Ethernet devices together and making them act as a single network segment. It has multiple input/output (I/O) ports, in which a signal introduced at the input of any port appears at the output of every port except the original incoming.

An operating system or OS is a software program that enables the computer hardware to communicate and operate with the computer software. Without a computer operating system, a computer and software programs would be useless. Network Specifications and Location - Control over the Security of Information

At the time of configuration, the mobile computing device - connectable to the hardware device, such as a multimedia display device - is paired with the SSID of the client's network and the router's MAC, AP or network hub, this pairing ensures that in the event of a theft, the mobile computing device does not present the contents even if all the requirements to operate correctly are met, because it will work only when connected to the network for which it was configured.

Likewise, the mobile computing device at the time of configuration is paired with the location of the client's network or place of instalment, and this pairing ensures that in the event of a theft, such mobile computing device does not present the contents even if all the requirements to operate correctly are met, because it will work only when connected to the network for which it was configured.

The present invention is an innovative advantageous solution for solving and/or minimizing:

• The difficulty in publishing contents on tv sets, remotely;

• The difficulty in publishing contents on tv sets without previously programming;

• The difficulty in displaying different formats of contents at the same time or sequentially;

• Ability to schedule the publishing of certain contents; • The need for heavy and/or expensive hardware structure;

• High energy consumption for offering available and active 24h/7h solutions;

• Background noise from commonly used electronic and hardware equipment;

• Reduced mobility of commonly used infrastructures;

• Difficulty in managing contents;

• Difficulty of creating sequences of contents without using video editing software tools.

• Management of TV sets organized individually, in groups or otherwise arranged;

• Managing local OS updates

• Large network bandwidth consumption due to the constant need for access;

Digital Rights Management (DRM) is a class of technologies that are used by hardware manufacturers, publishers, copyright holders, and individuals with the intent to control the use of digital content and devices after sale; there are, however, many competing definitions.

With first-generation DRM software, the intent is to control copying; with second-generation DRM, the intent is to control executing, viewing, copying, printing and altering of works or devices. The term is also sometimes referred to as copy protection, copy prevention, and copy control, although the correctness of doing so is disputed. DRM is a set of access control technologies.

According to an embodiment of the present invention, the provided solution is used in the context of a model of operationalization, allowing the login and record to be made by the authorized user (customer) , validating the rights of transmission every 24h, wherein these rights have a similar behaviour to the DRM but maintain cache this information, which allows the mobile computing device to confirm and validate their rights of transmission even when it is offline.

The rights of transmission result from the payment of the provided service, together with the use of the present invention .

The File Transfer Protocol (FTP) is a standard network protocol used to transfer computer files from one host to another host over a TCP-based network, such as the Internet .

FTP is built on client-server architecture and uses separate control and data connections between the client and the server. FTP users may authenticate themselves using a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) . SSH File Transfer Protocol (SFTP) is sometimes also used instead, but is technologically different.

Modular Communication

The isolation of the module regarding configuration (screen structure, areas, times of passage, source addresses, fonts, colours etc.) of the content's module, allows the user to enjoy a total freedom in the hosting of the contents, which may even be hybrid or 100% closed in networks without external communication. The module of contents is any file server, cloud, FTP or even a web server in http or https communication.

Dynamic Construction of Areas

Allows for the creation of multiple areas of contents by simply dragging the mouse or other hardware device on the display screen. This automatically triggers the assignment of a timeline or schedule to these areas, to which multiple multimedia contents may be added, such as video, images, Powerpoint®, widgets, etc.

These contents are managed in a temporal manner and can take its own "natural" time, for example contents such as video, or "non-natural" wherein the time is set on its timeline area

Proactive Cache Management

Along with the settings and configurations verified by the mobile computing device, a validation of the capacity required to store all the contents added to the timeline takes place, so that the equipment only transfers the contents once, even though the timeline is changed, it can identify the ID corresponding to such contents and does not require a subsequent download.

If the necessary cache is greater than the capacity of the equipment, it will delete and background download only the necessary data for assuring the content's display and reproductio .

HTML Pages Reproduction

Allows the user to manage HTML pages as a PNG image, and this HTML reproduction allows the user to set HTML pages from different sources which may overlap and their overlapping generates a final content without being able to identify that it is not the same page.

In this manner, the user achieves the reproduction of contents on TV sets without visible areas of contents.
