By deploying the chroma key panel from the chair, stowage, mobility, and efficiency are enhanced during video production.

FIELD OF THE INVENTION

The present invention relates generally to a chair and chroma key photography backdrop assembly for broadcasting or video conference. More so, the chair is equipped with at least one accessory retention arm to retain multiple broadcasting devices and props. In addition, the chair and backdrop assembly provide a chair having a supportive shock absorber and at least one detachable accessory retention arm, a collapsible chroma key panel deployable directly behind the actor and to the sides of the chair, one or more cameras operable in front of the chair, and a sound system operatively connected to a microphone in the camera, both being stowable and operable from the accessory retention arms; whereby an actor sits in the chair, and is viewable in front of the collapsible chroma key panel such that the cameras layer the image of the actor and a video image together or separately based on color hues, or chroma range.

BACKGROUND OF THE INVENTION

With the development of internet and social media, an individual online broadcasting or video conference is increasingly popularized in modern society. Not only celebrities or professional actors but also common people throughout all the industries are streaming online. It can be determined that broadcasting or video conference online will spread more widely in the future with the blooming of innovations in communication and the internet.

The broadcasting or video conference is suitable for everyone or any group, but the quality of broadcasting is quite different. Especially for the common people, the broadcasting or video conference effect can be greatly influenced by the condition of hardware or environment on the stream, including the selection of the live broadcast background or backdrop, the use of broadcasting or video conference apparatus, etc. Accordingly, with the thriving of streaming media, the related industry and market demand are increasing. For example, many people who want to achieve a good broadcasting or video conference effect and attract more viewers and subscribers, are contriving to design an attractive and fancy streaming or recording effect in some aspect, such as background, sound effect, visual effect, publicity effect, equipment, and the like, but most live broadcast's quality depends on by individual performance on the camera. Thus, the broadcasting or video conference effect for average people who has no experience on performance is poor.

Therefore, a demand to facilitate the live streaming for common people is proposed, especially to develop the technology on the hardware or accessory of live streaming in order to enhance the attraction and adaptability of the live show and recording. Some attention has been drawn to the development of a specified chair and backdrop for the live broadcast.

Throughout the prior art, engineers or designers have conceived some prototypes on the chair or the backdrop for the live broadcast. However, these chair design inventions were basically limited on the configuration of the chair itself, such as the comfortability, flexibility, and foldability, rather than on the improvement of live broadcast effects in entirety. The majority of actors or users during the broadcasting or video conference are still holding the broadcasting device in their hands or using an external bracket to support the device. It will cause inconvenience when the device needs to be moved or held for a long time. For example, the actor will be exhausted, and the images captured by the device are not stable, consequently resulting in an inferior efficiency and quality of the broadcasting.

On the other hand, some engineers have already manufactured the portable and detachable colorful backdrop panels, which can be attached to the backrest of the chair at the live streaming. Nevertheless, these designs specimens for backdrop panels have some flaws. For instance, the color or image patterns on the backdrop are not changeable; the pictorial elements on the backdrop are stationary; the under-way change of a backdrop panel will interrupt the live streaming show.

Thus, there is an urgent need for enhancing the live broadcast's quality, especially for common people.

In one embodiment of the present invention presented inFIGS. 1-6, a chair and chroma key photography backdrop assembly100leverages the effect of chroma key photography with a collapsible chroma key panel112that is integrated and deployable directly behind an actor200and to the sides of the chair102on which an actor200sits during broadcast. The chroma key panel112deploys directly behind, and to the left and right side of the actor200sitting on the chair102. The chair102has at least one accessory retention arm comprising sidewalls that form a cavity sized and dimensioned to retain broadcast equipment, including cameras400, sound systems, lights, and fans. The chair102also has a shock absorber108to absorb shock impulses from the actor200who is sitting on the chair102. Chroma key photography software in the cameras400separate the solid color of the chroma key panel112from the actor200sitting in the chair102, and replaces the solid color background of the chroma key panel112with a virtual image or video, such that the actor200appears to be in front of a virtual image or video. By deploying the chroma key panel112from the chair102, stowage, mobility, and efficiency are enhanced during video production.

One objective of the present invention is to integrate a green screen into a chair102, and enable the chair102to stow video production supplies, such as a portable desk, a fan a light source, a microphone, a sound system, one or more cameras400, and a communication device.

Another objective is to create a clean and tidy environment for broadcasting or video conference in which all supplies are condensed into a simple chair102.

Yet another objective is to create the privacy effect of a room from a chair102and integrated green screen.

An exemplary objective is to hide the location of the actor200, as the cameras400and chroma key panel112allow broadcasting or video conference from any location.

Additional objectives are to provide chroma key photography software that separates the actor200in the chair102from the chroma key panel112.

Additional objectives are to generate images and videos of advertisements on the chroma key panel112behind the actor200.

Additional objectives are to provide an easy to use and manufacture chair102and chroma key photography backdrop assembly100.

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 chair102with a chroma key panel112and other broadcasting or video conference equipment.

As referenced inFIG. 1, the assembly100provides a unique chair102that is sized and dimensioned to receive an actor200during filming of a video during broadcast. The chair102has a sitting portion104, such as a padded seat that an actor200can sit on during broadcast. The chair102also has a backrest portion106that the actor200can lean back on for lumbar and lower back support. The chair102provides a foundation for the actor to speak, act, and present information from. The chair102may also include a wheel portion110that enables mobility. This can include wheels and rollers on a foundation base.

In some embodiments, the chair102has a supportive shock absorber108. The shock absorber108helps support the weight of the actor200and any objects that is stored in the chair102. The shock absorber108rests adjacently to the sitting portion104, providing vertical support. However, in alternative embodiments, the supportive shock absorber108rests adjacent to the backrest portion106. In this manner, the load or shock waves generated by the weight of the actor200during broadcasting or video conference is absorbed and dampened by either, or the sitting portion104and the backrest portion106. In one non-limiting embodiment, the supportive shock absorber108includes a coil spring that has an adjustable coil strength. Optionally, the shock absorber108can apply a gas lift mechanism to support the sitting portion.

In yet other embodiments, the chair102includes at least one accessory retention arm that are detachably attached to the backrest portion106of the chair102. The accessory retention arms provide support for the arms of the actor200, 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 cameras400, and a communication device. The cameras400can be deployed in front of the chair102for capturing images and video of the actor200in front of a chroma key panel112, as described below.

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 actor200and can be held at a desired position by the accessory retention arms or mounts. One or more cameras400can 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.

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 arms110a-bcan 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.

In yet another example of the utilization of the accessory retention arms,FIG. 6illustrates a perspective view of multiple accessory retention arms600a,600b,600ccarrying various accessories, such as a fan608for cooling the actor during broadcast; a water spray602to enable the actor drinking water during broadcast; a table606for holding laptops, keyboards, papers and eating off; a ring light604for 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 light604. The accessory retention arms600a,600b,600care adjustable around the actor for easy access to the accessories.

Turning now toFIG. 3, the assembly100provides a collapsible chroma key panel112that is integrated into the chair102. This unique combination creates a single chair102stores and broadcasts with internal broadcast equipment, and a chroma key panel112, creating a compacted broadcasting or video conference system. The chroma key panel112may include by a resilient flat surface defined by a solid color for capturing video images with the one or more cameras400. In one embodiment, the chroma key panel112is a surface that does not reflect much light or create shadows, such as a muslin fabric or synthetic green screen known in the art.

The chroma key panel112is deployable directly behind the actor and to the sides of the chair102, possible stowing and deploying from the accessory retention arms. In some embodiments, the chroma key panel112slidably deploys and retracts into a housing. In other embodiments, the chroma key panel112may fold or telescopically slide between deployed and retracted positions. In other alternative embodiments, the chroma key panel112stows and deploys directly from the accessory retention arms. The chroma key panel112can also swivel from behind the chair102to a retracted position in the accessory retention arms. In any case, the resilient configuration of the chroma key panel112allows for various means to deploy directly from the housing, the backrest portion106, or the sitting portion104.

AsFIG. 4shows, the chroma key panel112may extend from directly behind the chair102(and the actor200in the chair102), or to the left and right sides of the chair102. This creates a panoramic view around the actor200. In other embodiments, the actor200can be facing away from the cameras400, looking directly at the chroma key panel112.

For example,FIG. 5illustrates 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 panel112is in the line of sight behind the actor200while sitting on the chair102.

It is known in the art that by using a camera directly in front and facing the actor200, the chair102with chroma key panel112backdrop can separate the actor200from the background; thereby generating a virtual image or video in place of the solid color of the chroma key panel112. Further, a sound system operatively connects to a microphone in the camera. The cameras400and the sound system are both stowable and deployable from the cavity of the accessory retention arms.

In one exemplary use, a wheeled chair102with a green screen background is angled to surround the actor200. With the cameras on the left and right and back and front of the actor200, each camera can capture the actor200and separate the actor200from the background. This is achieved by each camera individually and capturing the actor200from 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 actor200from the chroma key panel112. Camera 2 is left facing, separating the actor200from the chroma key panel112. Camera 3 is right facing, separating the actor200from the chroma key panel112. Camera 4 is rear facing, separating the actor200from the chroma key panel112.

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 actor200. Furthermore, the cameras may be attached directly to the chroma key panel112or stowed inside the accessory retention arms.

In operation of the assembly100, one or more cameras400are operable in front of the chair102for capturing videos and images of the actor200. The cameras400are positional in front of the chair102and the chroma key panel112that extends behind. Thus, when an actor200sits the chair102, the actor200is viewable in front of the collapsible chroma key panel112, such that the cameras layer the image of the actor200and 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. 3illustrates 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 panel112.

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.

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.

In one embodiment of the present invention presented inFIG. 13, a chair and chroma key photography backdrop assembly1300leverages the effect of chroma key photography with a collapsible chroma key panel12that is integrated and deployable directly from a chair on which an actor sits during broadcasting. The chroma key panel112deploys 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 arm1301comprising sidewalls that form a cavity sized and dimensioned to retain broadcast equipment1302, 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 equipment1302is a mobile phone with a camera. A chroma key photography software in the mobile phone separates the solid color of the chroma key panel112from the actor sitting in the chair, and replaces the solid color background of the chroma key panel112with 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 panel112from the chair, stowage, mobility, and efficiency are enhanced during video production.

In one preferable embodiment of the present invention presented inFIG. 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 actor200from the chroma key panel112. Said Camera 1 can be a mobile phone1302with a camera. Camera400bis left facing, separating the actor from the chroma key panel112. Camera400cis right facing, separating the actor from the chroma key panel112. Camera400dis rear facing, separating the actor from the chroma key panel112. In this embodiment, an accessory retention arm1301fixed under the bottom of the sitting portion of the chair can hold the front camera angled to the actor.

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 phone1302with 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 panel112or held inside the accessory retention arm1301.

The present invention also provides some different assemblies with the chair to make the broadcasting attractive, as shown inFIG. 15andFIG. 16. In another embodiment as shown inFIG. 15, the chair optionally equipped with accessory retention arms has a larger and higher backrest portion1506. A pair of angel wings1504is attached on the back of the backrest portion1506, so that the actor sitting on the chair looks like wearing an angle to attract the viewers on a broadcasting. The pair of angel wings1504can be attached detachably via sticking or tying. Optionally, the chair contains a headrest1502. The headrest1502is mounted on the backrest portion1504, and the height of the headrest1502is adjustable.

Likewise, in a changeable embodiment as shown inFIG. 16, the chair has a backrest portion1506, headrest1602and decoration1604. Preferably, the decoration1604is attached on the headrest1602detachably. Preferably, the decoration1604is shaped to a pair of ears of some animals including a cat, rabbit, dog, etc. or character decoration including hats and head dresses. The headrest1602is mounted on the backrest portion1506, and the height of the headrest1602is adjustable. Those varied decorations assembled with the chair enhance the appealing during a broadcasting.

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.

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

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 inFIG. 1.

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 portion104achieves more stabilization of the phone or camera held by the arm to prevent the broadcasting or video conference image from being shaked and vibrated.
