[0089] In another aspect, the capture videos by the four cameras are combined by chroma key photography software to create a three-dimensional playback or broadcast.

[0090] The above embodiment creates the adjustability and interchangeability of different backdrops and the recordings images.

[0091] In one embodiment of the present invention presented in FIGS. 1-6, a chair and chroma key photography backdrop assembly 100 leverages the effect of chroma key photography with a collapsible chroma key panel 112 that is integrated and deployable directly behind an actor 200 and to the sides of the chair 102 on which an actor 200 sits during broadcast. The chroma key panel 112 deploys directly behind, and to the left and right side of the actor 200 sitting on the chair 102. The chair 102 has at least one accessory retention arm comprising sidewalls that form a cavity sized and dimensioned to retain broadcast equipment, including cameras 400, sound systems, lights, and fans. The chair 102 also has a shock absorber 108 to absorb shock impulses from the actor 200 who is sitting on the chair 102. Chroma key photography software in the cameras 400 separate the solid color of the chroma key panel 112 from the actor 200 sitting in the chair 102, and replaces the solid color background of the chroma key panel 112 with a virtual image or video, such that the actor 200 appears to be in front of a virtual image or video. By deploying the chroma key panel 112 from the chair 102, stowage, mobility, and efficiency are enhanced during video production.

[0092] One objective of the present invention is to integrate a green screen into a chair 102, and enable the chair 102 to stow video production supplies, such as a portable desk, a fan a light source, a microphone, a sound system, one or more cameras 400, and a communication device.

[0093] Another objective is to create a clean and tidy environment for broadcasting or video conference in which all supplies are condensed into a simple chair 102.

[0094] Yet another objective is to create the privacy effect of a room from a chair 102 and integrated green screen.

[0095] An exemplary objective is to hide the location of the actor 200, as the cameras 400 and chroma key panel 112 allow broadcasting or video conference from any location.

[0096] Additional objectives are to provide chroma key photography software that separates the actor 200 in the chair 102 from the chroma key panel 112.

[0097] Additional objectives are to generate images and videos of advertisements on the chroma key panel 112 behind the actor 200.

[0098] Additional objectives are to provide an easy to use and manufacture chair 102 and chroma key photography backdrop assembly 100.

[0099] Those skilled in the art will recognize that it is common for performers and entertainers to broadcast (streaming) and record videos from their home. With many competitive performers and streamers, the performer must keep their viewers entertained and engaged. Watching a performer with the same background and environment for many sessions becomes tedious and tiresome, and boring for the viewer. Also broadcast performers (streamers) are able to earn money based on the volume quantity of their viewer base and also from advertisers that pay to place their logo, product and service to the viewer base. The present invention creates a compact, cost-effective broadcasting system that combines a chair 102 with a chroma key panel 112 and other broadcasting or video conference equipment.

[0100] As referenced in FIG. 1, the assembly 100 provides a unique chair 102 that is sized and dimensioned to receive an actor 200 during filming of a video during broadcast. The chair 102 has a sitting portion 104, such as a padded seat that an actor 200 can sit on during broadcast. The chair 102 also has a backrest portion 106 that the actor 200 can lean back on for lumbar and lower back support. The chair 102 provides a foundation for the actor to speak, act, and present information from. The chair 102 may also include a wheel portion 110 that enables mobility. This can include wheels and rollers on a foundation base.

[0101] In some embodiments, the chair 102 has a supportive shock absorber 108. The shock absorber 108 helps support the weight of the actor 200 and any objects that is stored in the chair 102. The shock absorber 108 rests adjacently to the sitting portion 104, providing vertical support. However, in alternative embodiments, the supportive shock absorber 108 rests adjacent to the backrest portion 106. In this manner, the load or shock waves generated by the weight of the actor 200 during broadcasting or video conference is absorbed and dampened by either, or the sitting portion 104 and the backrest portion 106. In one non-limiting embodiment, the supportive shock absorber 108 includes a coil spring that has an adjustable coil strength. Optionally, the shock absorber 108 can apply a gas lift mechanism to support the sitting portion.

[0102] In yet other embodiments, the chair 102 includes at least one accessory retention arm that are detachably attached to the backrest portion 106 of the chair 102. The accessory retention arms provide support for the arms of the actor 200, while also serving as a unique storage site for broadcasting equipment. In some embodiments, the accessory retention arms are elongated, and include sidewalls that form a cavity that is sized and dimensioned to retain various types of broadcast equipment. This equipment may include, without limitation, a portable desk, a mobile phone, a monitor, a fan a light source, a microphone, a sound system, one or more cameras 400, and a communication device. The cameras 400 can be deployed in front of the chair 102 for capturing images and video of the actor 200 in front of a chroma key panel 112, as described below.

[0103] In one exemplary assemblage of broadcasting equipment: a portable desk provides a flat surface or to placement of items. A fan provides wind effects for dynamic video broadcast and video capture. A light source, such as a lamp, provides light effects for dynamic video broadcast and video capture. A microphone picks up sound from the actor 200 and can be held at a desired position by the accessory retention arms or mounts. One or more cameras 400 can also be retained at a desired position by the accessory retention arms or mounts. A smart device, such as a smart phone or tablet provides easy access to video controls and video displays. All of these components, and more can be stowed in accessory retention arms.

[0104] In yet other embodiments, the assemblage of broadcasting equipment provides a sensation of realism to the actor of the scene, setting, interactive game or virtual reality environment. For example, the accessory retention arms can retain an aroma diffuser, which is operable to diffuse at least one aroma. The accessory retention arms can also hold a smoke diffuser to help diffuse smoke from broadcasting special effects, or simply from a cigarette/cigar. To help cool down the actor, the accessory retention arms 1 10a-b can retain a water spray for spraying a mist on the actor. This can help cool the actor or provide hydration to the actor. In other embodiments, a vibration stimulation motor is integrated into the chair or retained in the cavity of the retention arms. The vibration stimulation motor is operable to vibrate the sitting portion and the backrest portion. This creates a massaging effect for the actor.

[0105] In yet another example of the utilization of the accessory retention arms, FIG. 6 illustrates a perspective view of multiple accessory retention arms 600a, 600b, 600c carrying various accessories, such as a fan 608 for cooling the actor during broadcast; a water spray 602 to enable the actor drinking water during broadcast; a table 606 for holding laptops, keyboards, papers and eating off; a ring light 604 for casting an even light onto the objector (actor) and reducing shadows in the face, while illuminating the eyes of actor; and a mobile communication device holder for holding a smart phone, tablet, and the like. Optionally, the mobile communication device holder is mounted in the inner of the ring light 604. The accessory retention arms 600a, 600b, 600c are adjustable around the actor for easy access to the accessories.

[0106] Turning now to FIG. 3, the assembly 100 provides a collapsible chroma key panel 112 that is integrated into the chair 102. This unique combination creates a single chair 102 stores and broadcasts with internal broadcast equipment, and a chroma key panel 112, creating a compacted broadcasting or video conference system. The chroma key panel 112 may include by a resilient flat surface defined by a solid color for capturing video images with the one or more cameras 400. In one embodiment, the chroma key panel 112 is a surface that does not reflect much light or create shadows, such as a muslin fabric or synthetic green screen known in the art.

[0107] The chroma key panel 112 is deployable directly behind the actor and to the sides of the chair 102, possible stowing and deploying from the accessory retention arms. In some embodiments, the chroma key panel 112 slidably deploys and retracts into a housing. In other embodiments, the chroma key panel 112 may fold or telescopically slide between deployed and retracted positions. In other alternative embodiments, the chroma key panel 112 stows and deploys directly from the accessory retention arms. The chroma key panel 112 can also swivel from behind the chair 102 to a retracted position in the accessory retention arms. In any case, the resilient configuration of the chroma key panel 112 allows for various means to deploy directly from the housing, the backrest portion 106, or the sitting portion 104.

[0108] As FIG. 4 shows, the chroma key panel 112 may extend from directly behind the chair 102 (and the actor 200 in the chair 102), or to the left and right sides of the chair 102. This creates a panoramic view around the actor 200. In other embodiments, the actor 200 can be facing away from the cameras 400, looking directly at the chroma key panel 112.

[0109] For example, FIG. 5 illustrates a rear view of the back of the head of the actor sitting in front of a collapsible chroma key panel, representing the view from the camera in back of the actor and the retention arm in front of the actor holding another chroma key backdrop. This provides a back of the head view of the actor. This camera angle is necessary to make a 3D video or 360° video of the actor. In any case, the chroma key panel 112 is in the line of sight behind the actor 200 while sitting on the chair 102.

[0110] It is known in the art that by using a camera directly in front and facing the actor 200, the chair 102 with chroma key panel 112 backdrop can separate the actor 200 from the background; thereby generating a virtual image or video in place of the solid color of the chroma key panel 112. Further, a sound system operatively connects to a microphone in the camera. The cameras 400 and the sound system are both stowable and deployable from the cavity of the accessory retention arms.

[0111] In one exemplary use, a wheeled chair 102 with a green screen background is angled to surround the actor 200. With the cameras on the left and right and back and front of the actor 200, each camera can capture the actor 200 and separate the actor 200 from the background. This is achieved by each camera individually and capturing the actor 200 from four different directions, including a front view, a rear view, a left-side view, and a right-side view. For example, Camera 1 is front facing, separating the actor 200 from the chroma key panel 112. Camera 2 is left facing, separating the actor 200 from the chroma key panel 112. Camera 3 is right facing, separating the actor 200 from the chroma key panel 112. Camera 4 is rear facing, separating the actor 200 from the chroma key panel 112.

[0112] The four camera angles are combined by chroma key photography software to create a three-dimensional playback or broadcast of the accessory retention arms. Playback of the video in a specific format and layout can create a three-dimensional, holographic, or virtual reality version of the actor 200. Furthermore, the cameras may be attached directly to the chroma key panel 112 or stowed inside the accessory retention arms.

[0113] In operation of the assembly 100, one or more cameras 400 are operable in front of the chair 102 for capturing videos and images of the actor 200. The cameras 400 are positional in front of the chair 102 and the chroma key panel 112 that extends behind. Thus, when an actor 200 sits the chair 102, the actor 200 is viewable in front of the collapsible chroma key panel 112, such that the cameras layer the image of the actor 200 and a video image together or separately based on color hues, or the chroma range. The use of a background layer displays dynamically changing graphics, videos, and advertisements. This creates more interesting and entertaining content. FIG. 3 illustrates a frontal view of the actor sitting in front of a collapsible chroma key panel with a video replacing the solid color of the collapsible chroma key panel 112.

[0114] In the below descriptions, the present invention also presented some alternative embodiments specified with a single chair for broadcasting, without an assembled part of the chroma key panel. It is for sure that the optional combination of the chair with a chroma key panel (for example, chroma key panel 112 mentioned above) in those alternative embodiments can be achieved and is included in the protection of the present invention.

The tables create space that can be used to place props during broadcasting. For example, laptops, keyboards, food, drinks or any items that needs to be presented or utilized during the broadcasting or video conference can be placed on the tables so that the actor can access the items on the table in handy. In addition, the mobility and detachability of the tables facilitate the actor to sit down or stand up in different postures.

[0137] As another changeable embodiment presented in FIG. 12, an additional arm 1203 fixed under the bottom of the sitting portion of the chair 1200 extends over the table's edge to hold a device, preferably a mobile phone 1204 in front of an actor during the broadcasting. The arm 1203 can be an accessory retention arm; preferably it can be flexible or bendable; preferably it consists of multiply joints. Such this configuration for the arm 1203 adjusts the position of the mobile phone 1204 or its holding device to set the camera of the align to the presented object or the actor interchangeably during the broadcasting. The actor's hands are free rather than holding the device. Also, the table can create space to place the keyboards, laptops, food and drinks. In addition, the actor can rest his/her hands on the connected table. The comfortability and adjustability of the actor can boost the quality and efficiency of the broadcasting.

[0138] In one embodiment of the present invention presented in FIG. 13, a chair and chroma key photography backdrop assembly 1300 leverages the effect of chroma key photography with a collapsible chroma key panel 12 that is integrated and deployable directly from a chair on which an actor sits during broadcasting. The chroma key panel 112 deploys directly behind the actor and to the sides of the chair, specifically to the left and right side of the actor sitting on the chair. The chair has at least an accessory retention arm 1301 comprising sidewalls that form a cavity sized and dimensioned to retain broadcast equipment 1302, optionally choosing from mobile phones, cameras, sound systems, lights, and fans, etc. The chair also has a shock absorber to absorb shock impulses from the actor who is sitting on the chair. In this embodiment, the broadcast equipment 1302 is a mobile phone with a camera. A chroma key photography software in the mobile phone separates the solid color of the chroma key panel 112 from the actor sitting in the chair, and replaces the solid color background of the chroma key panel 112 with a virtual image or video, such that the actor appears to be in front of a virtual image or video. By deploying the chroma key panel 112 from the chair, stowage, mobility, and efficiency are enhanced during video production.

[0139] In one preferable embodiment of the present invention presented in FIG. 14, multiple cameras are angled to surround the actor. With the cameras on the left and right and back and front of the actor, each camera can capture or record the actor and separate the actor from the background via the chroma key photography software respectively. This is achieved by each camera individually and capturing the actor from four different directions, including a front view, a rear view, a left-side view, and a right-side view. For example, Camera 1 is front facing, separating the actor 200 from the chroma key panel 112. Said Camera 1 can be a mobile phone 1302 with a camera. Camera 400b is left facing, separating the actor from the chroma key panel 112. Camera 400c is right facing, separating the actor from the chroma key panel 112. Camera 400d is rear facing, separating the actor from the chroma key panel 112. In this embodiment, an accessory retention arm 1301 fixed under the bottom of the sitting portion of the chair can hold the front camera angled to the actor.

[0140] The recordings of four cameras are combined by chroma key photography software to create a three-dimensional playback or broadcast of the actor. The device can be the mobile phone 1302 with a camera. Preferably, the mobile phone is held by the accessory retention arm. Playback of the video in a specific format and layout can create a three-dimensional, holographic, or virtual reality version of the actor. Furthermore, the cameras may be attached directly to the chroma key panel 112 or held inside the accessory retention arm 1301.

[0141] The present invention also provides some different assemblies with the chair to make the broadcasting attractive, as shown in FIG. 15 and FIG. 16. In another embodiment as shown in FIG. 15, the chair optionally equipped with accessory retention arms has a larger and higher backrest portion 1506. A pair of angel wings 1504 is attached on the back of the backrest portion 1506, so that the actor sitting on the chair looks like wearing an angle to attract the viewers on a broadcasting. The pair of angel wings 1504 can be attached detachably via sticking or tying. Optionally, the chair contains a headrest 1502. The headrest 1502 is mounted on the backrest portion 1504, and the height of the headrest 1502 is adjustable.

[0142] Likewise, in a changeable embodiment as shown in FIG. 16, the chair has a backrest portion 1506, headrest 1602 and decoration 1604. Preferably, the decoration 1604 is attached on the headrest 1602 detachably. Preferably, the decoration 1604 is shaped to a pair of ears of some animals including a cat, rabbit, dog, etc. or character decoration including hats and head dresses. The headrest 1602 is mounted on the backrest portion 1506, and the height of the headrest 1602 is adjustable. Those varied decorations assembled with the chair enhance the appealing during a broadcasting.

[0143] The invention includes but not limits all the embodiments above. Especially, the parts of the chair and the assembly are interchangeable, additional or omittable between different embodiments contingent.

[0144] Alternatively, in all the embodiments of the present invention presented above, the said chair can be the same chair as shown in FIG. 1.

[0145] Alternatively, in all the relevant embodiments of the present invention presented above, the said collapsible chroma key panel can be the same chroma key panel as shown in FIG. 1.

[0146] Alternatively, all the arms mentioned above in the all the embodiments can be accessory retention arm; preferably it can be flexible or bendable; preferably it consists of multiple joints. Such this configuration for the chair can free the actor's hands and make the actor more comfortable and flexible instead of being tired and nervous. In addition, the fixation of the arm under the sitting portion 104 achieves more stabilization of the phone or camera held by the arm to prevent the broadcasting or video conference image from being shaked and vibrated.

[0147] Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
