Abstract
Abstract In a raster-scan display of bowling score information in conventional format, wherein the identity of each player is displayed and corresponding items of pinfall data and score data for each player are displayed in separate rows, improved readout means access digital data storage means only once in reading out corresponding items of both pinfall data and score data for each player, thereby cutting the readout rate to one-half of what would otherwise be required. This is accomplished by taking advantage of the fact that the size of the alphabet of different characters required to display the identity of the players is greater than the sum of the sizes of the respective alphabets of characters needed to provide pinfall data and characters needed to provide score data. A single data register of sufficient capacity to store the number of bits required for the characters of the player identity alphabet is operated as a single register for the raster-scan line display of player identity information and, alternatively, is divided into two smaller-sized registers for the display of corresponding items of pinfall data and score data.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
In a raster-scan display system incorporating storage means, and readout means coupled to said storage means for use in electronically displaying stored game-score data of a given kind of game in a standardized format on a video-signal display device while the game is progressing, said format including an individual strip region thereof devoted to any given player with a first predetermined portion of said strip region having displayed therein a single line of characters identifying said given player and with a second predetermined portion of said strip region having displayed therein k lines of characters defining score information of said given player, k being a first plural integer, wherein a binary word having at least n bits is required to uniquely distinguish each character of a given alphabet of player-identifying characters, n being a second plural integer, and wherein the number of bits mi of a binary word required to uniquely distinguish each character of a preselected alphabet for the ith respective ordinal one of said k lines of score-information is sufficiently smaller than n so that
Claim 2
Dependent Claim

In a raster-scan display system incorporating storage means, and readout means coupled to said storage means for use in electronically displaying stored game-score data of a given kind of game in a standardized format on a video-signal display device while the game is progressing, said format including an individual strip region thereof devoted to any given player with a first predetermined portion of said strip region having displayed therein a single line of characters identifying said given player and with a second predetermined portion of said strip region having displayed therein k lines of characters defining score information of said given player, k being a first plural integer, wherein a binary word having at least n bits is required to uniquely distinguish each character of a given alphabet of player-identifying characters, n being a second plural integer, and wherein the number of bits mi of a binary word required to uniquely distinguish each character of a preselected alphabet for the ith respective ordinal one of said k lines of score-information is sufficiently smaller than n so that
Claim 3
Dependent Claim
29 words
The system defined in claim 1, wherein said time generating means defines a raster scan for said display which is substantially normal to the length of a strip region.
Claim 4
Dependent Claim
237 words
The system defined in claim 1, wherein said given kind of game is bowling and said standardized format is that of a bowling score sheet in whIch said given player strip region extends horizontally with said first portion being located relatively to the left and said second portion being located relatively to the right, said second portion consisting of an upper row in which pinfall data for each of 10 bowling frames may be displayed and a lower row in which bowling score data for each said ten frames may be displayed; wherein said time generating means defines a raster scan for said display which is substantially vertical, defines a first binary signal having a given binary value when said raster scan is in the relatively left portion of its scan field in which said first portion is located and having an opposite binary value when said raster scan is in the relatively right portion of its scan field in which said second portion is located, and defines a second binary signal having a given binary value when a raster scan is traversing an upper row and an opposite binary value when a raster scan is traversing a lower row, and wherein said seconod means applies to said digital-to-video converter a digital address selected from the at least n-bits of said readout binary word in accordance with the respective binary values of said first and second signals.
Claim 5
Dependent Claim
14 words
The system defined in claim 3, wherein said digital-to-video converter includes a read-only memory.
Claim 6
Dependent Claim
91 words
The system defined in claim 3, wherein said given number of bits in each readout binary word is equal to the n bits of the binary word defining the digital address of player-identifying character and said second means divides said given number of bits into first and second binary words each having half said given number of bits, whereby k 2, m1 n/2 and m2 n/2, said first binary word corresponding to a character of said pin-fall data and said second binary word corresponding to a character of said bowling-score data.
Claim 7
Dependent Claim
16 words
The system defined in claim 5, wherein said raster scan display consists of two interlaced fields.
