Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
A television transmission system comprising: means for generating a first field of a high-resolution television picture; first storing means for storing said first field and for reading out sequentially different contiguous portions of the stored first field, said first storing means including means for scanning in said first field with a first number of lines, means for selecting in a particular order different contiguous portions of the stored first field for scanning out as fields with a second and lower number of lines, and means reading out by scanning the selected contiguous portions; means for serially emitting each of the read out contiguous portions as a complete field of a low-resolution television picture; means for serially receiving each of said emitted fields; and reassembling means for reassembling the received fields to form a single field having the picture contents of said first field for display as a single complete field.
Claim 2
Dependent Claim
150 words
A television transmission system comprising: means for generating a first field of a high-resolution television picture; first storing means for storing said first field and for reading out sequentially different contiguous portions of the stored first field, said first storing means including means for scanning in said first field with a first number of lines, means for selecting in a particular order different contiguous portions of the stored first field for scanning out as fields with a second and lower number of lines, and means reading out by scanning the selected contiguous portions; means for serially emitting each of the read out contiguous portions as a complete field of a low-resolution television picture; means for serially receiving each of said emitted fields; and reassembling means for reassembling the received fields to form a single field having the picture contents of said first field for display as a single complete field.
Claim 3
Dependent Claim
60 words
The system of claim 1 further comprising means for generating fields of general broadcast television pictures, means for transmitting the generated fields of general broadcast pictures and the emitted fields associated with the read out contiguous portions with said emitted fields being interspersed in said generated fields, and means for controlling said receiving means to receive only said emitted fields.
Claim 4
Dependent Claim
134 words
A television transmission system comprising: means for generating a first field of a high-resolution television picture; first storing means for storing said first field and for reading out sequentially different contiguous portions of the stored first field; means for serially transmitting each of the read out contiguous portions as a complete field of low-resolution television picture; means for serially receiving each of said transmitted fields; and reassembling means for reassembling the received fields to form a single field having the picture content of said first field for display as a single complete field, said reassembling means comprises second storing means for storing each of the serially received fields in a particular order to reassemble the picture content of said first field, and high-resolution display means for displaying the contents of said second storing means.
Claim 5
Dependent Claim
134 words
A television transmission system comprising: means for generating a first field of a high-resolution television picture; first storing means for storing said first field and for reading out sequentially different contiguous portions of the stored first field; means for serially transmitting each of the read out contiguous portions as a complete field of low-resolution television picture; means for serially receiving each of said transmitted fields; and reassembling means for reassembling the received fields to form a single field having the picture content of said first field for display as a single complete field, said reassembling means comprises second storing means for storing each of the serially received fields in a particular order to reassemble the picture content of said first field, and high-resolution display means for displaying the contents of said second storing means.
Claim 6
Dependent Claim
61 words
The television transmission system of claim 3 further comprising means for generating and transmitting fields of general broadcast information, and further comprising means for suBstituting for fields of general broadcast information the fields representing the read out portions, means for identifying the substituted fields and said receiving means including means for transmitting to said second storing means only said substituted fields.
Claim 7
Dependent Claim
39 words
The television transmission system of claim 3 wherein said second storing means includes means for scanning in fields with a first number of lines and means for scanning out a field with a second and larger number of lines.
Claim 8
Dependent Claim
38 words
The television transmission system of claim 5 wherein said first storing means includes means for scanning in said first field with said second number of lines and means for scanning out fields with said first number of lines.
Claim 9
Dependent Claim
42 words
The television transmission system of claim 5 wherein said transmitting means includes means for uniquely identifying each field, and said second storing means includes means for storing each of the uniquely identified fields in a particular position of said second storing means.
