Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
A digital interface between a source of digital video picture elements and a memory, each picture element comprising at least four bits, said interface comprising: (a) means connected to said source for receiving and storing data groups comprising at least the four most significant bits of data corresponding to each video picture element and for forming said data groups into words; (b) means for performing a direct memory address transfer of said words to said memory; (c) means for monitoring the number of data groups received from said source and the number of data groups transferred to said memory during a predetermined period of time; and (d) means for ensuring that the number of data groups received from said source equals the number of data groups transferred to said memory during said predetermined period.
Claim 2
Dependent Claim
134 words
A digital interface between a source of digital video picture elements and a memory, each picture element comprising at least four bits, said interface comprising: (a) means connected to said source for receiving and storing data groups comprising at least the four most significant bits of data corresponding to each video picture element and for forming said data groups into words; (b) means for performing a direct memory address transfer of said words to said memory; (c) means for monitoring the number of data groups received from said source and the number of data groups transferred to said memory during a predetermined period of time; and (d) means for ensuring that the number of data groups received from said source equals the number of data groups transferred to said memory during said predetermined period.
Claim 3
Dependent Claim
24 words
An interface according to claim 1 wherein said transfer of words to said memory occurs at rates between two and ten megabytes per second.
Claim 4
Dependent Claim
125 words
A digital interface between a source of digital video picture elements and a memory, said video picture elements comprising at least four bits, said interfacing comprising: (a) means connected to said source for receiving and storing data groups comprising at least the four most significant bits of data corresponding to each video picture element and for forming said data groups into words, said means for receiving and storing said data groups and for forming said groups into words comprising a first-in, first-out register file, said register file comprising at least four registers, each register comprising at least four storage levels, each level comprising means for storing at least four-bits; and (b) means for performing a direct memory address transfer of said words to said memory.
Claim 5
Dependent Claim
125 words
A digital interface between a source of digital video picture elements and a memory, said video picture elements comprising at least four bits, said interfacing comprising: (a) means connected to said source for receiving and storing data groups comprising at least the four most significant bits of data corresponding to each video picture element and for forming said data groups into words, said means for receiving and storing said data groups and for forming said groups into words comprising a first-in, first-out register file, said register file comprising at least four registers, each register comprising at least four storage levels, each level comprising means for storing at least four-bits; and (b) means for performing a direct memory address transfer of said words to said memory.
Claim 6
Dependent Claim
34 words
An interface according to claim 3 comprising means for reading successive data groups into one level of successive ones of said registers and for simultaneously reading a word from another level of said registers.
