Abstract
Abstract A video display apparatus (18,20) includes a video data generator (12) which generates video data of a still picture (32) and a moving picture (34) (graphic data) on the basis of still picture pattern, still picture character code, moving picture character code and etc. programmed in an external storage (16) unit in advance. A microprocessor (10) applies, in accordance with priority data for the still picture and the moving picture and mode data (26) both programmed in the external storage unit in advance, first priority data (46) to the video data of the still picture character and second priority data (66) to the video data of the moving picture character, respectively. A priority encoder (130) selects a still picture character or a moving picture character having the highest priority on the basis of the first and second priority data, and applies the number of that character to a decoder (132). The decoder outputs a gate control signal (144) in accordance with the number. In response to the gate control signal, the video data of the character having the highest priority among the respective still picture character and the moving picture character is outputted from a gate (80).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
A video display apparatus which displays a plurality of still picture cells in an overlaid state, said video display apparatus, comprising: still picture video data generating means for generating video data of a still picture character to be displayad regarding each of said plurality of still picture cells; first priority data applying means for applying first priority data to the video data of the still picture character from said still picture video data generating means; selecting means for determining priority based on said first priority data applied to each still picture character and for selectively outputting the video data of one still picture character of a still picture having highest priority among said plurality of still picture cells; and display means for displaying the still picture character outputted selectively by said selecting means.
Claim 2
Dependent Claim
91 words
A video display apparatus in accordance with claim 1, further comprising mode signal generating means for generating a mode signal to designate the number of the still picture cells to be displayed, said still picture video data generating means generating video data of the still picture character regarding the still picture cell designated by the mode signal, wherein said selecting means selects the video data of the still picture character of the still picture cell having highest priority in that mode based on the mode signal and the first priority data.
Claim 3
Dependent Claim
69 words
A video display apparatus in accordance with clalm 1 or claim 2, further comprising transparency detecting means for detecting whether or not each still picture character is a transparent picture based on the video data outputted from said still picture video data generating means, wherein said selecting means determines the priority except for the video data of the still picture character detected being transparent by said transparency detecting means.
Claim 4
Dependent Claim
40 words
A video display apparatus in accordance with claim 3, wherein said selecting means is provided with means for generating specific video data when it is detected by said transparency detecting means that all of said still picture characters are transparent.
Claim 5
Dependent Claim
88 words
A video display apparatus in accordance with claim 1, further comprising: moving picture video data generating means for generating video data of a moving character; and second priority data applying means for applying second priority data to the video data of the moving picture character from said moving picture video data generating means, wherein said selecting means selectively outputs the video data of said one still picture character or the picture data of said moving picture character based on the first priority data and the second priority data.
Claim 6
Dependent Claim
108 words
A video display apparatus in accordance with claim 5, further comprising mode signal generating means for generating a mode signal to designate the numer of the still picture cells to be displayed, said still picture video data generating means generating video data of the still picture character regarding the still picture cell designated by the mode signal, wherein said selecting means selects the video data of the still picture character of the still picture cell having the highest priority in that mode or the video data of the moving picture character based on the mode signal and the first priority data as well as the second priority data.
Claim 7
Dependent Claim
156 words
An external storage unit used in association with a video display apparatus which displays a plurality of still picture cells in an overlaid state on a monitor screen on based on video data of still picture characters generated by a still picture video data generator, said external storage unit comprising: still picture character code storing means for storing a still picture character code that designates a still picture character to be displayed, said still picture character video data generator generating the video data on the basis of the still picture character code; and priority data storing means for storing first priority data that designates priority of each still picture character, wherein said video display apparatus includes selecting means for determining priority of each still picture character on the basis of the first priority data and for selectively outputting the video data of one still picture character having highest priority among said plurality of still picture cells.
Claim 8
Dependent Claim
90 words
An external storage unit in accordance with claim 7, further comprising mode data storing means for storing mode data that designates the number of said still picture cells to be displayed, said still picture video data generator generating the video data of the still picture character regarding the still picture cell designated by said mode data, wherein said selecting means selects the video data of the still picture character of the still picture cell having highest priority in that mode based on the mode data and the first priority data.
Claim 9
Dependent Claim
106 words
An external storage unit in accordance with claim 7, further comprising: moving picture character code storing means for storing a moving picture character code that designates a moving picture character to be displayed; and second priority data storing means for storing second priority data that designated priority of the moving picture character, wherein said video display apparatus includes moving picture video data generator for generating video data of the moving character, and said selecting means selectively outputs the video data of said one still picture character or the video data of said moving picture character based on the first priority data and the second priority data.
