Abstract
Abstract For the sake of elevating significantly user's flexibility in edits of video signals, the memory control device for video editors comprises a storage means for storing at least one or more of title data composed of video image data representing title signals and key data used for controlling the title signal; a first memory for storing video image data and which is provided with a data reading means for reading the video image data so as to be capable of displaying the data in the form of a video image; a second memory for storing a key data and which is provided with a video image controlling means for controlling a video image to be displayed on the basis of the key data read; a specifying means for specifying a memory into which is to be written the title data; and a writing means which reads the video image data and the key data of title data to write both the data read into the first memory and the second memory, respectively, in the case when the first memory is specified by the specifying means, while which reads only the key data of the title data to write the data read into the second memory in the case when the second memory is specified by the specifying means.

Claim 1
Independent Claim
222 words
A memory control device for video editors comprising: a storage means for storing at least one or more of title data composed of video image data representing title signals and key data used for controlling the title signal; a first memory for storing video image data and which is provided with a data reading means for reading the video image data so as to be capable of displaying said data in the form of a video image; a second memory for storing key data and which is provided with a video image controlling means for controlling a video image to be displayed on the basis of the key data read; a specifying means for specifying a memory into which is to be written the title data which have been stored in said storage means; and a writing means which reads the video image data and the key data of title data from said storage means to write both the data thus read into said first memory and said second memory, respectively, in the case when said first memory is specified by said specifying means, while which reads only the key data of the title data from said storage means to write the data thus read into said second memory in the case when said second memory is specified by said specifying means.

A memory control device for video editors comprising: a storage means for storing at least one or more of title data composed of video image data representing title signals and key data used for controlling the title signal; a first memory for storing video image data and which is provided with a data reading means for reading the video image data so as to be capable of displaying said data in the form of a video image; a second memory for storing key data and which is provided with a video image controlling means for controlling a video image to be displayed on the basis of the key data read; a specifying means for specifying a memory into which is to be written the title data which have been stored in said storage means; and a writing means which reads the video image data and the key data of title data from said storage means to write both the data thus read into said first memory and said second memory, respectively, in the case when said first memory is specified by said specifying means, while which reads only the key data of the title data from said storage means to write the data thus read into said second memory in the case when said second memory is specified by said specifying means.
Claim 3
Dependent Claim
164 words
A memory control device for video editors comprising: a memory for storing key data used for controlling video images to be displayed and which is provided with a video image controlling means for controlling the video images on the basis of the key data read; a storage means for storing at least one or more of either of video image data or key data; an extracting means for extracting selectively data from said storage means; and a writing means for writing the key data extracted selectively by said extracting means into said memory with no conversion of the key data thus extracted in the case where the data extracted selectively by said extracting means are the key data, while writing the video image data extracted selectively by said extracting means into said memory with conversion of the video image data thus extracted selectively by said extracting means in the case where the data extracted selectively by said extracting means are the video image data.
Claim 4
Dependent Claim
164 words
A memory control device for video editors comprising: a memory for storing key data used for controlling video images to be displayed and which is provided with a video image controlling means for controlling the video images on the basis of the key data read; a storage means for storing at least one or more of either of video image data or key data; an extracting means for extracting selectively data from said storage means; and a writing means for writing the key data extracted selectively by said extracting means into said memory with no conversion of the key data thus extracted in the case where the data extracted selectively by said extracting means are the key data, while writing the video image data extracted selectively by said extracting means into said memory with conversion of the video image data thus extracted selectively by said extracting means in the case where the data extracted selectively by said extracting means are the video image data.
Claim 5
Dependent Claim
164 words
A memory control device for video editors comprising: a memory for storing video image data and which is provided with a data reading means for reading the video image data so as to be capable of displaying said data in the form of a video image; a storage means for storing at least one or more of either of the video image data or key data used for controlling a video image to be displayed; and a writing means for writing the video image data extracted selectively by said extracting means into said memory with no conversion of the video image data thus extracted in the case where the data extracted selectively by said extracting means are the video image data, while writing the key data extracted selectively by said extracting means into said memory with conversion of the key data thus extracted selectively by said extracting means in the case where the data extracted selectively by said extracting means are the key data.
