Description

[0001] SYSTEM FOR SHARING MULTIMEDIA CONTENT, ESPECIALLY FOR MEDICAL APPLICATIONS

[0002] The present invention relates to a system for sharing multimedia content including audio and video files, especially for medical applications. The subject of the invention is an audio and video file sharing system that allows the sharing of real-time or recorded events via an IT network and provides users remote access to recorded events.

[0003] It is a common problem in the medical field that several specialists cannot be physically present in a surgery room, particularly due to long distances or time constraints. This can hinder the introduction of new surgical procedures and the exchange of experiences. In many situations, it would be important to be able to follow a surgery live from anywhere in the world and even participate in it as an active observer or advisor.

[0004] There are several solutions for sharing audiovisual content among remote users. One such system is the MedVC system (MedVC.eu), a medical video communication platform designed for the fast and secure sharing of visual information and videos used in surgical and medical procedures. The system enables live streaming of videos and images, as well as remote consultations between doctors and surgeons. The MedVC system also supports training processes, as it allows the recording and reviewing of medical surgeries and procedures. This can be particularly useful for young doctors or professionals learning different surgical techniques during their medical training.

[0005] US11118905B2 describes a modular video imaging system. This system consists of a control module and multiple input modules that can receive and process image data generated by various types of cameras. The control module is responsible for providing general functions such as user interface management and data processing.

[0006] US20100295870A1 discloses a medical imaging system that works with multiple input sources, converts the signal format of the video data stream from the multiple sources to a format suitable for the selected display, and is also capable of combining synchronous and asynchronous signals, combining graphics, images, video or data geometrically, and to scale graphics, images, video or data geometrically and non-geometrically.

[0007] The problem with the known solutions is that the analogue or digital audio and video signals of the individual multimedia data stream providers are based on different standards and cannot be connected to the same signal processing and transmission equipment.

[0008] Therefore, the objective of the invention is to provide a system capable of receiving, processing and transmitting multimedia data streams, i.e. analogue or digital audio and video signals, from different equipment, from different manufacturers, according to different standards to remote users for the purposes of remotely controlled medical interventions, remote diagnostics or consultations, and distance learning. The invention also provides a system that allows the receiving, processing and sharing of multimedia data streams from multiple surgical devices at multiple locations simultaneously.

[0009] During developing the invention, we started out from a system that is used for sharing audiovisual, multimedia content including audio and video files, particularly for medical applications, and comprises the following:

[0010] - at least one unit providing audio and / or video signals arranged at the site of an event, such as a medical surgery procedure, and / or at least one unit providing pre-recorded and stored audio and / or video signals;

[0011] - a unit connected to the units providing audio and / or video signals, for receiving and processing a multimedia data stream containing audio and / or video signals,

[0012] - a multimedia content provider unit connected to the unit receiving and processing the multimedia data stream, and

[0013] - remote user stations connected to the multimedia content provider unit via an IT network, wherein the remote user stations contain devices suitable for displaying the received multimedia content.

[0014] The aim of the invention can be achieved in the most general sense with a system wherein

[0015] - the at least one unit providing audio and / or video signals and / or the at least one unit providing pre-recorded and stored audio and / or video signals has an analogue or digital audio and / or video signal output according to any standard,

[0016] - the unit receiving and processing a multimedia data stream containing audio and / or video signals that is connected to the units providing audio and / or video signals has inputs that receive analogue or digital audio and / or video signals according to any standard,

[0017] - the unit receiving and processing the multimedia data stream includes a converter unit that converts the various standard analogue or digital audio and / or video signals into analogue or digital audio and / or video signals according to the desired standard.

[0018] This design of the invention defines a system to which equipment from any manufacturer providing analogue or digital audio and / or video signals according to any standard can be connected, thereby enabling the development of a manufacturer-independent system.

[0059] - a microphone with analogue and / or digital audio output.

[0060] The invention is described below by the preferred embodiments shown in the drawings, wherein Figure 1 shows a block diagram of the minimum configuration system according to the invention, Figure 2 shows a block diagram of a multi -site expandable system according to the invention, and Figure 3 is a diagram of a unit receiving and processing multimedia data streams containing audio and / or video signals, connected to units providing audio and / or video signals, with input and output connectors according to various standards, and

[0061] Figure 4 is a schematic block diagram of the unit receiving and processing the multimedia data stream.

[0062] Figure 1 shows a block diagram of a minimum configuration system according to the invention, where a single unit 1 providing analogue or digital audio and / or video signals is shown at the site of medical or surgical procedure, whose output providing analogue or digital audio and / or video signals according to any standard is connected to the input of unit 2 receiving and processing multimedia data stream including analogue or digital audio and / or video signals that receives analogue or digital audio and / or video signals according to any standard. Since the unit 2 receiving and processing multimedia data stream including analogue or digital audio and / or video signals has multiple inputs, several units 1 providing analogue or digital audio and / or video signals can be connected to it simultaneously. The unit 2 receiving and processing multimedia data stream including analogue or digital audio and / or video signals is conveniently connected via a wired or wireless local network to a multimedia content provider server unit or relay server 3. The remote users 5 can connect to the server 3 in a secure and controlled way via the internet 4. The digital audio and video data stream displayed for the remote users 5 is provided by the server 3. The diagram shows two remote user stations 5, one of which has a desktop computer and the other has a mobile terminal, such as a smartphone.

[0063] Figure 2 shows a block diagram of a multi-site, expandable system according to the invention, with multiple remote user stations 5. Figure 2 shows the arrangement of the system’s components in case of a larger institutional building, such as a hospital. In this example, the unit 1 providing analogue or digital audio and / or video signals is located in the same place as the unit 2 receiving and processing multimedia data stream containing the analogue or digital audio and / or video signals connected to it, for example in a surgery room 6. In the diagram, unit 1 is connected to the receiving and processing unit 2 in surgery room 6, but as the receiving and processing unit 2 has multiple analogue and digital inputs, multiple units 1 providing analogue or digital audio and / or video signals can be connected to it. In this configuration, the multimedia content provider server unit or relay server 3 is not located in the same place as or near the receiving and processing unit 2, but further away in the building, for example in a server room 7. Furthermore, the system can also be implemented with the multimedia content provider server unit 3 being located outside the hospital building, in a data centre.

[0064] In this case, the receiving and processing unit 2 is also connected to the multimedia content provider server units or relay server 3 via a wired or wireless local area network. The diagram shows two server units 3 in the server room 7, where the upper server unit 3 is connected to one receiving and processing unit 2, and the lower server unit 3 is connected to two receiving and processing units 2, but the number of receiving and processing units 2 connected to the server units 3 is of course not limited to the example shown.

[0065] The connection of remote users 5 to the relay servers 3 is provided in a secure and controlled way via the internet 4. The digital audio and video data stream displayed to the remote users 5 is provided by the servers 3. The diagram shows four remote user stations 5, two of which have a desktop computer and the other two have a mobile terminal, such as a smartphone.

[0066] Figures 3 and 4 show the internal structure of the unit 2 receiving and processing multimedia data streams containing analogue or digital audio and / or video signals already shown in Figures 1 and 2, with input and output connections. The unit 2 receiving and processing multimedia data stream is conveniently located in a plastic enclosure, which has a modular design and allows for expansion and connection of additional units. The units located in the enclosure are cooled by a built-in fan (not shown in the drawing), and ventilation openings are provided in the enclosure for heat dissipation. The central unit of the unit 2 receiving and processing multimedia data stream containing analogue or digital audio and / or video signals is a computer 30, to which input connectors according to various standard are connected via an input interface and signal converter unit. Unit 1 providing analogue audio and / or video signals can be connected to an RCA (Radio Corporation of America) type analogue input 21. The A / D conversion of analogue signals is performed by a converter unit 31, the output of which is connected to the USB port of the computer 30 via USB (Universal Serial Bus) connectors and cables 25. The RCA analogue input 21 supports the transmission of analogue video signals of various standards (NTSC - National Television System Committee, PAL - Phase Alternating Line), which is important for medical endoscopes, as they often use such systems. After digitisation, the analogue signals can be processed by the computer 30. Since the signal received and digitised by the RCA connectors 21 can be transmitted to the computer 30 via USB connectors 25, the converter performs RCA -USB conversion.

[0067] Unit 1 providing digital audio and / or video signals can be connected to the DVI (Digital Visual Interface) input 22, the HDMI (High Definition Multimedia Interface) input 23 or the SDI (Serial Digital Interface) input 24. Digital input signals do not require digitisation, but digital signals are also transferred through the USB connector 25 and cable to the USB connector of computer 30. In this case, no digitisation takes place, only an HDMI-USB conversion. For digital video signals, the supported resolution is typically 720p, 1080p, or even 4K for new models. The USB connector used must be at least an USB 2.0 to ensure sufficiently fast data transfer. Conversion cables or connectors (e.g. DVI-HDMI) can also be used to ensure compatibility between individual devices. In case of digital signals arriving at the SDI digital video input 24, SDI / HDMI - SDI / USB conversion takes place. SDI (Serial Digital Interface) is a professional digital video transmission standard that is often used in media production and is increasingly common in medical and industrial fields where high-quality, stable video signals are required. An SDI input converter device allows SDI signals to be converted to other digital signals, such as HDMI or USB, so that they can be processed by a computer. The converter must have an SDI video input connector, an HDMI output connector, and a USB connector for computer connection and power supply.

[0068] The advantages of SDI video converters are the following:

[0069] - Image quality: SDI transmits uncompressed digital signals, which is necessary for professional recordings.

[0070] - Cable length support: SDI signals can travel long distances over long cables without loss of quality, making them suitable for use in larger surgery rooms and industrial locations.

[0071] - Synchronised sound and image: SDI is capable of keeping video and audio in sync, avoiding time discrepancies, which is particularly important for live broadcasts or recordings of surgical procedures.

[0072] - Reliability: SDI interfaces are designed with durable connectors, providing long -lasting and reliable connection even in professional use.

[0073] Types and formats

[0074] SDI versions based on the supported resolution and speed:

[0075] HD-SDI: Supports HD (1080p) resolution and typically operates at 1.485 Gbps.

[0076] 3G-SDI: Supports Full HD 1080p resolution at 60 fps, with a speed of 2.97 Gbps.

[0077] 6G-SDI and 12G-SDI: Designed for 4K resolution, it provides higher bandwidth, with 12G-SDI capable of up to 2160p / 60 fps.

[0078] If the surgical device does not have audio and / or video output, or if an audio and / or video transmission by personnel working on site is also required, it is possible to connect at least one independent camera 33 and / or microphone 34 to the computer 30, e.g. via USB ports 26. In case of a surgical procedure, remote consultation and distance learning are possible. The camera located in the surgery room shows the surgical area from an external view. The microphone allows the surgeon to present the surgical procedure.

[0079] The unit 2 receiving and processing multimedia data stream containing analogue or digital audio and / or video signals is connected to server 3 transmitting multimedia content via a wired or wireless network. Connection to the wired network is enabled, for example, via an RJ45 type wired network connection. Connection to the wireless network is enabled via a WiFi connection or a mobile internet connection (e.g. 5G). For this purpose, optionally a WiFi adapter or mobile internet adapter can be connected to the connector 29. In order to protect the IT system and data, individual multimedia content and transmission-related activities are classified into authorisation classes, and transmission takes place in accordance with these authorisation classes.

[0080] User access to the service is controlled in accordance with IT security policies.

[0081] The streaming server can only be accessed by those with streaming authorisation. For example, the following streaming authorisations can be defined;

[0082] - Stream manager: e.g. a doctor on site in the surgery room authorised to set up and control the transmission, can perform stream start / stop / pause operations, authorised to switch views between different inputs and scenes.

[0083] - Stream administrator: can remotely intervene in the stream, can access the server via an encrypted channel, authorised to compile and control the stream, can perform stream start / stop / pause operations, authorised to switch views between different inputs and scenes, can override user access.

[0084] - System administrator: can access the server via an encrypted channel, authorised to perform maintenance and operational tasks, authorised to perform settings, authorised to perform system backups and archiving, can perform monitoring tasks.

[0085] Access to shared multimedia content is granted on an invitation basis. Authorised users can register in the system, for example with their email address and username. To view the shared content, selected remote users receive an invitation to join a video conference via a link and a unique ID. Only the stream manager and stream administrator can authorise or deny remote users' access and participation in the stream.

[0086] Shared multimedia content may contain multiple audio, video, image or text data streams, which can be displayed alternately on a single screen or simultaneously in multiple windows. Multi-window display can be configured using a so-called scene planning. Scenes can be created by the stream manager and stream administrator. Scenes facilitate switching between different content combinations during live broadcasts. A broadcast usually consists of multiple video sources, such as an endoscope camera, ultrasound device video signal, and images from the camera showing the surgical procedure. To protect multimedia content shared with remote users over the internet, transmission can be secured using protocols such as TLS (Transport Layer Security), SRT (Secure Reliable Transport), and E2EE (End-to-End) encryption.

[0087] In addition to sharing multimedia content with remote users, the system also enables local display of content. For this purpose, the unit 2 receiving and processing multimedia data stream containing analogue or digital audio and / or video signals is also equipped with HDMI output connectors 28 and for example a local monitor, TV or projector can be connected to this output.

[0088] Devices with video output used during surgery allow the surgeon to obtain real-time images of the surgical site. Some examples of such devices are the following:

[0089] Endoscope: It is a thin, flexible tube with a camera at the end, which is inserted through a body cavity or a small incision. It is often used in laparoscopic surgery.

[0090] Laparoscope: This is a specialised endoscope used for abdominal surgeries. The camera image is projected onto a monitor, which helps the surgeon perform precise operations.

[0091] Surgical robot devices (e.g. Da Vinci robot): In these devices, the surgeon remotely controls the robot arms while viewing real-time video of the surgical site. This allows for extremely precise surgical procedures.

[0092] The use of the system according to the invention significantly advances the development of medical training and surgical techniques. With the use of modern communication and imaging technologies, such as 5G-based video streaming or AR (augmented reality) solutions providing remote access, remote participation enables doctors to learn new procedures and techniques, to optimise existing methods and to consult during operations.

[0093] Simultaneous streaming from multiple surgery rooms is made possible, allowing participating doctors to follow several different procedures and techniques in real time. The technological infrastructure used ensures high- quality, real-time video and audio transmission.

[0094] Medical device manufacturers offer solutions that enable the transmission or recording of video signals. Multimedia reception and processing units with analogue and / or digital inputs according to various standards enable the connection of devices with analogue and / or digital outputs according to various standards, thus ensuring independence from manufacturers.
