Description
FIELD OF THE INVENTION
[0001] The present innovation relates to devices commonly known as consumer electronics, in particular to an interconnected system for the wireless transmission of high-quality audio and video among consumer electronic devices.BACKGROUND OF THE INVENTION
[0002] Having detected the possibility of implementing the proposed system, it is necessary to investigate the previous technologies, seeking further advantages for consumers that could result from the application of this innovation, as well as the inventions and applications already existing worldwide in this regard.
[0003] The application ES2253968 to Vision Relax, published on 01-06-2006, proposes a device that enables the visualization of previously stored images on a physical medium and that must be reproduced from a decoder. The visualization of images is carried out in a device similar to glasses which also has integrated headphones, remote control and elastic characteristics that point to a comfortable and ergonomic experience by the end users. The patent application document also makes reference to proprietary program code and applications developed on the Linux platform. Patent application US2016 / 0309213 to Shenzhen TCL New Technology Co. published on 20-10-2016, refers to a method of synchronization of audio / video signals that includes: acquiring a delay data value of an audio signal formed by a wireless module of an audio / video signal synchronization device and a wireless audio device; According to a display format of a video data to be reproduced, calculate the playing time of each frame of the video data to be reproduced; According to the delay data value and the reproduction time of each frame, calculate the number of frames to be stored in buffer memory, and generate and store in the buffer memory the frames with the corresponding number; And according to an audio / video playback instruction, reproduce the buffered frames and video data to be played sequentially, and transmit audio data corresponding to the video data that will be reproduced to the wireless audio device for audio data playback while playing frames. An audio / video signal synchronization apparatus is also described.
[0004] In a way similar to that described in the previous paragraph, it is constituted the patent ES2376213 to Telefonica SA, published on 12-03-2012. In which the procedure is stated by which the distribution of audio and video signals for wireless mechanisms in indoor environments using DVB-T signals in the 5 GHz spectrum would be possible. This invention, as stated in the same patent applies directly to the construction and deployment of communication networks and their connection with other networks, not being the same limited to equipment within the so-called mass consumption electronics.
[0005] Patent ES2354079 to QUALCOMM INC, published on 09-03-2011, states an alternative method for synchronizing wireless audio and video signals. In this case, the claims again focus on alternative methods for synchronizing audio and video data by providing coding, decoding, buffering and transfer control characteristics typical of common RTP signals in content distribution applications.
[0006] Patent MX213002574 to RAMDEO PRADEEP, published ON 16-09-2014, presents the invention of a system that includes a wireless camera for generating audio and video feeds by a first person, while a second person, looks at the audio and video feeds through a device with internet access, located in a different geographical position.
[0007] Patent MX2007002295 to QUALCOMM IN, dated 11-05-2007, presents an optimization method for the transmission of audio and video data in wireless systems. This application focuses mainly on the video conferencing sector that involves several people and that during the transmission the audio and video data of one of the interlocutors must be sent to all other participants based on the selections made by computer programming stored within a server that determines the speaker by predefined criteria.
[0008] The PCT patent WO2006 / 073863 to INTEL CORP +, published on 13-07-2006, is categorized within the field of multicast transmissions, specifically within the improvement of existing methods, where different characteristics of a transmission system for multimedia content are outlined that could involve various existing devices such as memories of various types, personal computers, personal digital assistants and personal communication systems including cell phones. Within this context, the creation of an RMA (Reliable Multicast Agent) is crucial in order to increase the reliability and robustness of the link, thus seeking to ensure minimum losses in the eventual receiver-sender transmission.
[0009] Having explored all these aspects already registered, it is evident that this system provides in itself a substantial advance regarding the interconnection capacity between consumer electronics, its relationship with the end user through graphic tools on the television or monitor; as well as the ability to be multiplexed between each other providing comfort and flexibility to everyday applications.
[0010] Patent application US 2006 / 0209745 A1 discloses a system for wireless transmission which comprises a source device having a A / V source connected to a wireless transmitter by means of a first wired interface, and a sink device having a wireless receiver connected to a A / V presentation system by means of a second wired interface.
[0011] Patent application US 2008 / 235733 A1 discloses a gateway which connects home devices (such as personal computers) with remote devices via wireless modem and via an external cable / DSL service, both of which are distributed via wired or wireless router.SUMMARY OF THE INVENTION
[0012] The described device enables the transmission of audio and video between sending and receiving devices, given that an exponential increase in access to such technologies has been registered draws attention that the interconnection characteristics have not advanced significantly in regard to traditional methods.
[0013] By applying the present system, is sought to update and improve the current devices specifically for their characteristics of audio and video (I-A / V) interconnection and transmission characteristics. Thus being, a conventional consumer electronics reproduction or decoding equipment equipped with the transmission system; constituting an I-A / V transmitter which can be interconnected with another conventional consumer electronics device called the I-A / V receiver.
[0014] Typically, for applications of this type the I-A / V receiver will be a conventional television which has been equipped since its manufacture with wireless technology that allows it to be interconnected with a wide variety of I-A / V emitting equipment which can also be equipped with the present transmission system since its assembly and manufacturing phase.
[0015] In addition, and taking advantage of the processing capabilities of the I-A / V receiver equipment, the possibility of interrelating these functionalities at a graphical level is conceived.
[0016] That is, users can choose directly on their television screens whether or not they want to use said wireless system for interconnection. Following this line of development, it is understandable that a same user would like to have several I-A / V emitting devices connected to the same I-A / V receiver, for which, by multiplexing such choice would be possible within the same 1-A / V receiver.
[0017] It is currently well known that wireless technologies for audio / video transmission have advanced significantly, however the traditional physical methods of link and transmission remain the default option for manufacturers of consumer electronics. The present proposal aims to be a first step towards the final elimination of the cables that are currently used to make the transmission of audio / video signals between devices that read / decode / transmit to others that normally function as receivers with all the steps and stages that this may imply.
[0018] However, the present solution does not have as an objective the elimination of the physical cables dedicated to the electrical supply of the different devices but implementing a method of wireless interconnection for the replacement of certain common physical wiring existing between devices classified within the so-called Consumer Electronics.
[0019] Such devices which include but are not limited to televisions, electronic entertainment systems, multimedia playback units, personal and industrial computers and cable signal coding terminals which normally include a physical means such a cable made of metallic material which extends from the device that originates the signal to the device that receives it, decodes, processes and transmits to the end user, usually by means of a screen which can be a Plasma, LCD or backlit light-emitting diodes (LED technology) type.
[0020] Another objective of the present application is the provision of a transmission system that can be applied to a range of manufacturers which, for simplicity, replicability, interconnection capacity, as well as low cost can be implemented in a variety of electronic equipment as mentioned in the previous paragraph.
[0021] Another objective of the present application is to provide an interconnection method that is easy to use by end users, which should not interact directly with the components dedicated to audio and video transmission either in the form of radio frequency waves or datagrams, bits or any other form / specification of wireless transmission.
[0022] Similarly, another objective of the present application is the mass elimination of traditional methods for transmitting audio / video signals within the field of consumer electronics. This, by implementing a safe method, not subject to common interference, whereby end users have a new experience of installing and using the devices within the category of consumer electronics which would have from their assembly phase dedicated components for the transmission and reception, so that they can be interconnected easily, inexpensive and without external physical cables.BRIEF DESCRIPTION OF THE DRAWINGS
