Abstract

A video exhibit stand and method of exhibiting informational programs comprises a housing having a plurality of large and small openings therein and arranged around the periphery thereof. A plurality of cathode ray tubes and audio speakers are supported within the housing with the screens of the cathode ray tubes secured within the large openings and the audio speakers secured within the small openings. Video transmitter means within the housing conducts informational programs recorded on cassette tapes to a four-way signal splitter which splits the video signal into four distinct but identical signals. These signals are conducted to the inputs of the cathode ray tubes and the audio signals are conducted to the audio speakers. The exhibit stand is portable and may be located at the juncture of hallways where people may view the cathode ray screens from all directions. A plurality of such video stands may be located at remote points in a large auditorium room or in separate remote rooms. A transmitter at a remote central station sends four distinct but identical signals to the plurality of remotely located video exhibit stands where they are received by the four-way signal splitter within the housing. The splitter within the housing further splits the signal into four distinct but identical signals carrying identical information. The signals are conducted to the inputs of the cathode ray tubes whereby the signals appear on the screens thereof for viewing from all angles.

Claims

1. A video exhibit stand comprising:

a housing having outer and inner walls and a vertically upwardly swinging closure;

a base in the form of an inverted dome for supporting said housing;

a standard secured to the base at one end thereof, and to the housing at the opposite end thereof;

a plurality of alternating larger and smaller openings within the walls of the housing and arranged around the periphery thereof;

a plurality of cathode ray tubes having inputs thereon supported within the housing and having the screens thereof secured within the larger openings;

audio speakers having inputs thereon supported within the smaller openings, said smaller openings alternating between the larger openings;

a video transmitter having output means thereon;

a four-way electronic signal splitter having input and output means thereon, said inputs connected to the outputs of the video transmitter whereby informational program signals are transmitted to the four-way electronic signal splitter;

cable means connecting the output of said four-way electronic signal splitter to the inputs of the cathode ray tubes; and

said four-way electronic signal splitter producing four distinct but identical informational signals which are conducted to the inputs of the cathode ray tubes where said informational programs appear on said screens.

2. A video exhibit stand as defined in claim 1, wherein:

said housing is spherical in form having an access opening at the top thereof, and said vertically upwardly extending closure is dome shaped corresponding to said opening.

3. Video exhibit stand as defined in claim 1, wherein:

said base has a plurality of feet secured at their ends to the end of said standard;

said feet extending radially horizontally outward from said standard; and

a plurality of hollow tubes secured in vertically orientation to the opposite ends of said feet;

a plurality of rods having upper and lower ends, the lower ends of which are inserted into said vertically oriented tubes; and

barrier means secured to the upper ends of said rods and incirclying said housing whereby people are prevented from walking into and knocking over said video exhibit stand.

4. Video exhibit stand as defined in claim 1, wherein:

said larger and smaller openings having border means on the outside thereof closing the juncture between the wall and the cathode ray tubes and audio speakers.

5. A video exhibit stand as defined in claim 1, wherein:

said video transmitter is located at a remote central location and having means for connecting the output of said transmitter to the four-way electronic signal splitter within the housing of the exhibit stand.

6. A video exhibit stand as defined in claim 1, wherein:

said closure is in the form of a dome corresponding to the access opening in said housing and a receiving antenna secured to said closure having means connecting said antenna to the four-way signal splitter within the housing for conducting the signals received thereon to said four-way electronic signal splitter within the housing of exhibit stand.

7. A video exhibit stand as defined in claim 1, wherein:

said video transmitter is a video cassette and said informational programs are pre-recorded on video cassette tapes.

8. A method of exhibiting informational programs comprising the steps of:

placing a plurality of video exhibit stands having multiple viewing screens around the periphery thereof at remote locations within a large auditorium or within different conference rooms in a convention center;

locating video transmitter means at a central station remote from the exhibit stands;

boosting the video signal prior to transmitting;

splitting the video signal into four distinct but identical signals containing identical informational programs;

transmitting said four distinct but identical signals to a four-way electronic signal splitter within each of the video exhibit stands;

splitting the signal by the four-way signal splitter within each of the video stands; and

displaying said informational programs on each of the screens of the cathode ray tubes of each of the video exhibit stands whereby people at said remote locations passing by or in proximity to said exhibit stands may view said screens from all directions.

9. A method of exhibiting informational programs as defined in claim 8, wherein:

said video transmitter means is a mini TV transmitter.

10. A method of exhibiting informational programs as defined in claim 8, wherein:

said video transmitter means is a cable television transmitter.
