SYSTEM AND METHOD FOR DISTRIBUTING MEDIA CONTENT FIELD OF THE INVENTION

[0001] The present invention relates to a system and method for providing media content to one or more viewers.

BACKGROUND OF THE INVENTION

[0002] At a large event, such as a sporting event like the Formula 1 Grand Prix or the Tour de France for example, an event attendee will not be able to view the action around the whole event area due to the size of the area. Accordingly, the viewer’s experience at these events is limited.

[0003] One known solution to this problem is to telecast the action on the track onto a big screen, where the video feed is captured by a video recording camera at different locations around the track. However, these big screens are not visible to all attendees at the event.

[0004] Existing systems for broadcasting video to a user device (such as a television screen or a mobile device) involve a video camera device for capturing a video feed, which is then transmitted to a remote station (or a remote server) for encoding the information into a format suitable for broadcasting and reception by the user equipment. These existing broadcasting systems suffer from latency issues. Therefore, while a user in the event area could tune into the broadcasted content on his/her mobile device to view the action around distant or other locations in the event area, the user’s viewing of this content on his/her mobile device will not be in realtime thereby limiting the viewer’s experience at the event.

[0005] An example of an existing system is described in United States Patent 9,064,011 B2 to Quickplay Media Inc. This document discloses a mobile media platform that receives content for subsequent transmission to a mobile device. The mobile media platform is arranged for encoding and transcoding, content tagging, unicast-multi-cast-broadcast switching, mediation, and settlement. The mobile 2017100647 02 Jun2017 2 media platform is a remote server that receives and stores source data. User electronic devices access the mobile media platform to view the source data. The use of a mobile media platform increases latency of the overall system and reduces the real-time viewing experience of the user.

[0006] Another example of an existing system is described in United States Patent Publication 2015/0026466 A1 to Wowza Media Systems, LLC. This document discloses a media sever for sending and receiving data from various devices. The media server communicates with playback devices that are configured to steam video content. The media server is also configured to authenticate user devices. The use of the media server as disclosed in this document also increases latency of the overall system.

[0007] A further example of an existing system is described in United States Patent Publication 2014/0282748 A1 to McNamee et al. This document discloses a method for distributing content feed of a live event via satellite. The use of the satellite for streaming video however greatly increases the overall latency of the system as well as increases the cost.

[0008] Another example of an existing system is described in United States Patent Publication 2011/0072450 A1 to Backchannelmdia Inc. This document discloses a system for linking content stored on a computer network with content broadcast over a television network. Broadcasting content over the television network however suffers from inherent latency from the point of capture to the point of viewing . Therefore, the system of this document is also not suitable for providing a real-time viewing experience to a user.

[0009] Embodiments of the present invention seek to provide a system for providing media content to one or more viewers with lower latency (i.e. substantially in real time) and/or to provide media content for high-density viewing and/or to at least provide the public with a useful choice. 3 2017100647 02 Jun2017

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[00038] Referring to Figure 1, the system 100 according to an embodiment of the present invention for distributing content to one or more user electronic devices 900 includes a digital video camera 120, an encoder 140, and a wireless access point 160.

[00039] The digital video camera 120 is configured capture content data from the real world. As user herein, ‘content data’ includes one or more of audio data, image data, and video data. The digital video camera 120 interfaces with the encoder 140 via a Serial Digital Interface (SDI) video interface. Flowever, according to other embodiments, the digital video camera 120 may interface with the encoder 140 via a High Definition SDI (HD-SDI) video interface or via a High Definition Multimedia Interface (HDMI) video interface, via a Display Port, Digital Visual Interface (DVI), or via a Universal Serial Bus (USB).

[00040] The digital video camera 120 is a physically separate device from the encoder 140. However, in other embodiments, the digital video camera 120 and the encoder 140 are part of the same device. For example, the encoder 140 may be housed within the digital video camera 120.

[00041] The encoder 140 is configured to receive the content data captured by the digital video camera 120 and encodes the data into a format suitable for reception by the user electronic devices 900. The format used by the encoder 140 is preferably H.264 format or MPEG-4 Part 10, Advanced Video Coding (AVC). The format used by the encoder may alternatively be H.265 format or MPEG-H Part 2. 10 2017100647 02 Jun2017 [00042] The encoder 140 is particularly configured for transmission over a transport stream having the following settings: a video packet identifier of 33; an audio packet identifier of 36; a program clock reference packet identifier of 33; and a program map table packet identifier of 32.

[00043] The encoder 140 is further configured to perform forward error correction (FEC) on the content data that is received by the transmitters. The FEC used by the encoder 140 is Pro MPEG FEC 10. The FEC is performed at a rate of less than about 20% of the transport stream bandwidth, which would result in a latency of less than 2 seconds.

[00044] The encoder 140 is configured for transmission over an average transport stream bandwidth of between about 500 kbps and about 4 Mbps, preferably about 1 Mbps and about 1.5 Mbps. The invention allows the system to operate for high density (i.e. transmission of data to a plurality of user electronic devices) at low bitrates of about 500 kbps to about 3 Mbps, while maintaining the high definition streaming. The encoder 140 is configured to transmit the content data to the transmitter(s) in a multicast configuration.

[00045] The specific encoding techniques and settings employed by the encoder 140 result in a latency of less than about 100ms. In contrast, the average latency for an existing conventional system can be between 100ms and 250ms.

[00046] The wireless access point 160 is configured to receive encoded content data from the encoder 140 and to transmit the encoded content data to the user electronic devices 900. The wireless access point 160 is configured to convert the multicast transmission from the encoder 140 into a unicast configuration, which is then transmitted to the user electronic devices 900.

[00047] The wireless access point 160 is configured to support transmission of the encoded content data to up to about 40 user electronic devices. As will be 11 2017100647 02 Jun2017 described in further detail below with reference to Figure 5, the system may comprise more than one wireless access point, wherein each wireless access point is configured to support transmission of content data to up to about 40 user electronic devices. The wireless access point 160 is configured to operate on a 2.4GHz frequency band and/or on a 5GHz frequency band. It will be understood that the wireless access point could be operated in accordance with one or more wireless local area network standards.

[00048] Where the wireless access point 160 is configured transmit the encoded content data in accordance with wireless standard IEEE 802.11a, the wireless access point 160 is configured to transmit content data at one or more data rates of about 18.0 Mbps, 24.0 Mbps, 36.0 Mbps, 48.0 Mbps, and 54.0 Mbps.

[00049] Where the wireless access point 160 is configured transmit the encoded content data in accordance with wireless standard IEEE 802.11 g, the wireless access point 160 is configured to transmit content data at one or more data rates of about 18.0 Mbps, 24.0 Mbps, 36.0 Mbps, 48.0 Mbps, and 54.0 Mbps.

[00050] Where the wireless access point 160 is configured transmit the encoded content data in accordance with wireless standard IEEE 802.11b, the wireless access point 180 is configured to transmit content data at one or more data rates of about 1.0 Mbps, 2.0 Mbps, 5.5 Mbps, and 11.0 Mbps.

[00051] Where the wireless access point 160 is configured transmit the encoded content data in accordance with wireless standard IEEE 802.11η, the wireless access point 180 is configured to transmit content data at one or more data rates of about 24.0 Mbps, 36.0 Mbps, 48.0 Mbps, and 54.0 Mbps.

[00052] Where the wireless access point 160 is configured transmit the encoded content data in accordance with wireless standard IEEE 802.11ac, the wireless access point 180 is configured to transmit content data at one or more data rates of about 24.0 Mbps, 36.0 Mbps, 48.0 Mbps, and 54.0 Mbps. 12 2017100647 02 Jun2017 [00053] Due to the closed-circuit nature of the system 100, the wireless access point 160 does not require any filtering and application control, which further improves the latency.

[00054] The specific settings employed by the wireless access point 160 result in a latency of less than about 200ms.

[00055] The user electronic device is configured to have a buffering time for content received from the transmitter of about 2 seconds.

[00056] Figure 2 shows the method 200 according to an embodiment of the present invention for distributing content data to one or more user electronic devices in an area, which may be an event area (such as a sporting arena for example). The method 200 involves the data capture device positioned in the area capturing a video feed (at 220), an encoder converting the video feed into a format suitable for reception by user electronic devices (at 240), and a transmitter (wireless access point) receiving the encoded video feed from the encoder (at 260) and transmitting the video feed to the user electronic devices (at 280).

[00057] It will be readily appreciated that the system 100 of Figure 1 and the method 200 of distributing content data of Figure 2 can be scaled accordingly depending on the size of the event area and the number of user electronic devices in the event area to be serviced. For example, there may be more than one data capture device positioned in the event area to capture content data from different locations in the event area in order to increase the user’s visibility of the event area. In this configuration, the data capture devices capture content data and communicate the data to the encoder for encoding and subsequent transmission to the user electronic devices via the transmitter. Alternatively, there may be more than one encoder provided in the event area that communicates with a respective one or more of the plurality of data capture devices. In addition, there may be more than one wireless access point to support a higher number of user electronic devices. Where there are a plurality of wireless access points, the wireless access points are arranged and configured to provide seamless data communication and coverage as 13 2017100647 02 Jun2017 the user electronic device moves from a first cell that is serviced by one wireless access point to a second cell that is serviced by another wireless access point.

[00058] Referring to Figure 3, a system 300 according to another embodiment of the present invention is disclosed for distributing content data to a user electronic device. The system 300 is similar to the system 100 of Figure 1, and like reference numerals used for the system 300 of Figure 3 with the addition of 200 indicate like elements as the system 100 of Figure 1. In the embodiment shown in Figure 3 however, the system 300 further comprises a server 370 for authenticating the user electronic device(s). In this embodiment, a network switch 350 is provided, which is configured to selectively control traffic between the server 370 and the encoder 340 to the wireless access point 360. The network switch may communicate traffic to and from the server via the Internet for example. The server 370 is configured to provide additional content to the user, which may be advertising (such as promotional content from event sponsors) and/or event messages. Unlike conventional systems however, the server does not receive content data from the data capture device 320 for subsequent transmission to the user electronic devices. In this way, the latency of the overall system is significantly reduced compared to conventional systems.

[00059] It will however be appreciated that, according to other embodiments of the invention, the network switch may not be provided. According to these other embodiments, the wireless access point is provided with inbuilt routing capabilities, which allows for data communication with the server via a network (which may be the Internet for example).

[00060] Figure 4 shows a timing diagram according to an embodiment of the present invention, particularly for the system shown in Figure 3. A user of an electronic device 900 seeking to access the content provided by the system will be required to first obtain authentication from the server 370. The user electronic device connects to the wireless access point 360 and sends a request for authentication (at 410) to the wireless access point 360, which is subsequently routed by the network switch (at 420), via the Internet for example, to the server 370. 14 2017100647 02 Jun2017 [00061] The server 370 receives the request for authentication and makes a determination as to whether the user electronic device is authorised to access the content provided by the system. The server may for example assess whether a user identification included in the request from the user electronic device corresponds to an existing identification stored in one or more computer data storage devices. The existing identifications in the data storage devices may be a list of attendees of the event in which the system is configured to operate for example. The server 370 sends its decision (at 430) as to whether the user electronic device 900 is authorised to access the content to the wireless access point 360, which subsequently transmits the decision (at 440) to the user electronic device 900 as to whether the user electronic device is authorised to access the content.

[00062] If the user electronic device 900 is granted access by the server 370 to the content, the user electronic device 900 is provided with an access token, which includes the settings for the user electronic device 900 to view the content data. The access token may for example define an access session by the electronic device to the content for a limited period of time. For a sporting event, the limited period of time may correspond to the duration of the sporting event for example.

[00063] The data capture device 320 transmits content data to the encoder 340 (at 450), which encodes the content data as described above. The encoded data is transmitted to the wireless access point (at 460) for subsequent transmission to the user electronic device 900 (at 470).

[00064] The server 370 may be configured to provide further content to the user electronic device 900, such as advertising material or event messages. Where the further content is desired to be transmitted to the user electronic device 900, the server 370 transmits the further content to the wireless access point 360 (at 480), which subsequently transmits the content to the user electronic device 900 (at 490).

[00065] Referring to Figure 5, a system 500 according to another embodiment of the present invention is disclosed for distributing content data to multiple user 15 2017100647 02 Jun2017 electronic devices 901, 902, 903 located in the event area. The system 500 is similar to the system 300 of Figure 3, and like reference numerals used for the system 500 of Figure 5 with the addition of 200 indicate like elements as the system 300 of Figure 3. In the embodiment shown in Figure 5 however, the system 500 includes multiple wireless access points 561, 562, 563. Each wireless access point 561, 562, 563 is positioned in the event area to increase the coverage for content data to be provided to the user electronic devices in the event area. In particular, each wireless access point 561, 562, 563 defines a cell, which is a geographic area, each a wireless access point is configured to provide content data to user electronic devices 901, 902, 903 located in the geographic area corresponding to its respective geographic cell. Each wireless access point is configured to provide content data to up to 40 user electronic devices in its respective cell. The wireless access points 561, 562, 563 are further positioned and configured such that if a user electronic device moves from one cell to another cell, there is a substantially seamless handover between the wireless access points for the moving user electronic device such that the user’s viewing of the content data on the user electronic device is uninterrupted as the user electronic device moves between cells.

[00066] The embodiment shown in Figure 5 shows the wireless access points 561, 562, 563 in communication with a single network switch 550 and a single encoder 540. It will be readily appreciated that more than one encoder and/or network switch may be provided, which can assist in reducing the latency for the user electronic devices.

[00067] In contrast to the existing systems that are described in the Background section for example, the present invention does not require an intermediate remote server for storing content from a data capture device and that is later accessible by one or more users. Rather, according to the present invention, the communication of data from the video camera to the user electronic device is more direct and therefore has a significantly improved latency for providing a real time viewing experience to a user. In particular, as described above, the video as captured by the video camera is provided directly from the camera to local encoder. The camera may be connected to the encoder by a physical connection for example to enable faster data transfer between the camera and the encoder. Once the data 2017100647 02 Jun2017 16 is encoded by the encoder into a suitable format, the encoded data from the encoder is provided directly to the transmitter for transmission to the user electronic devices. The encoder may be physically connected to the encoder by a physical connection for example to enable faster data transfer between the encoder and the transmitter. Thereby, in contrast to the existing systems, the present invention greatly reduces the latency and allows for content to be provided to the user in real-time.

[00068] Where the present invention requires a server (as described with reference to Figure 3 for example), the video camera is connected to the encoder via the network switch. However, because the network switch is only configured to direct the flow of traffic either to the server or to the transmitter, the network switch does not increase the latency of the overall system and does not significantly impact of the real-time viewing experience of the user.

[00069] Preferred embodiments of the invention have been described above by way of non-limiting example. Further modifications and variations may be made without departing from the scope of the invention.
