Video and audio editing system

Claim 2

Claim 3

A video and audio editing system as claimed in claim 1, wherein said time lag inputting means includes means for acquiring a first time lag which is a time by which audio data are fetched later or earlier than the fetching start time designated by an operator and means for acquiring a second time lag which is a time by which the fetched audio data exhibit silence beginning with the top thereof, and said table updating means updates the contents of said start time table and said end time table based on the fetched first and second time lags.

Claim 4

A video and audio editing system as claimed in claim 1, wherein said time lag inputting means is an instruction inputting apparatus manually operated by an operator who independently inputs a time lag.

Claim 5

A video and audio editing system wherein video data and audio data are fetched from an external apparatus onto a computer via a video board and an audio board, respectively, and stored in a storage medium, wherein said system comprises: a start time table and an end time table for storing a processing start time and a processing end time, respectively, for each scene to be fetched from said external apparatus; a time lag inputting means for inputting time lags inherent in fetching audio data from said external apparatus and placing said audio data on said audio board; wherein said time lags result from the inherent time required between requesting said external apparatus to begin playing previously recorded data and said previously recorded data being copied and placed in said storage medium, a table updating means for updating the contents of said start time table and said end time table based on the inputted time lags; and a control means for referring to the contents of said start time table and said end time table to control fetching start times and fetching end times of said video data and audio data and fetching the audio data while skipping data corresponding to the time lags.

Claim 6

A video and audio editing system wherein video data and audio data are fetched from an external apparatus onto a computer via a video board and an audio board, respectively, and stored in a storage medium, wherein said system comprises: a start time table and an end time table for storing a processing start time and a processing end time, respectively, for each scene to be fetched from said external apparatus; a time lag inputting means for inputting time lags inherent in fetching audio data from said external apparatus and placing said audio data on said audio board; wherein said time lags result from the inherent time required between requesting said external apparatus to begin playing previously recorded data and said previously recorded data being copied and placed in said storage medium, a table updating means for updating the contents of said start time table and said end time table based on the inputted time lags; and a control means for referring to the contents of said start time table and said end time table to control fetching start times and fetching end times of said video data and audio data and fetching the audio data while skipping data corresponding to the time lags.

Claim 7

A video and audio editing system as claimed in claim 4, wherein said time lag inputting means includes means for acquiring a first time lag which is a time by which audio data are fetched later or earlier than the fetching start time designated by an operator and means for acquiring a second time lag which is a time by which the fetched audio data exhibit silence beginning with the top thereof, and said table updating means updates the contents of said start time table and said end time table based on the fetched first and second time lags.

Claim 8

A video and audio editing system as claimed in claim 4, wherein said time lag inputting means is an instruction inputting apparatus manually operated by an operator who independently inputs a time lag.

Claim 9

A video and audio editing system wherein video data and audio data are fetched from an external apparatus onto a video board and an audio board, respectively, and subsequently stored in a storage medium, the system comprising: a start time table and an end time table for storing a relative start time and a relative end time, respectively, for each scene to be fetched from said external apparatus; a time lag inputting means for inputting time lags inherent in fetching and storing audio data from said external apparatus on said storage medium; wherein said time lags include the inherent time required for requesting said external apparatus to begin playing previously recorded data, the external apparatus beginning to play the recorded data, the data being transferred from the external apparatus to the audio board, the audio board processing the audio data, the audio data being transferred from the audio board to the storage device, and the audio data being placed in the storage medium, a table updating means for updating the contents of said start time table and said end time table based on the inputted time lags; and a control means for referring to the contents of said start time table and said end time table to control a reading start time and a reading end time from said storage medium and reading out the audio data from said storage medium while skipping data corresponding to the time lags representative of silence.

Claim 10

A video and audio editing system wherein video data and audio data are fetched from an external apparatus onto a video board and an audio board, respectively, and subsequently stored in a storage medium, the system comprising: a start time table and an end time table for storing a relative start time and a relative end time, respectively, for each scene to be fetched from said external apparatus; a time lag inputting means for inputting time lags inherent in fetching and storing audio data from said external apparatus on said storage medium; wherein said time lags include the inherent time required for requesting said external apparatus to begin playing previously recorded data, the external apparatus beginning to play the recorded data, the data being transferred from the external apparatus to the audio board, the audio board processing the audio data, the audio data being transferred from the audio board to the storage device, and the audio data being placed in the storage medium, a table updating means for updating the contents of said start time table and said end time table based on the inputted time lags; and a control means for referring to the contents of said start time table and said end time table to control a reading start time and a reading end time from said storage medium and reading out the audio data from said storage medium while skipping data corresponding to the time lags representative of silence.

Claim 11

A video and audio editing system as claimed in claim 7, wherein said time lag inputting means includes a means for acquiring a first time lag which is a time by which audio data are fetched later or earlier than the fetching start time designated by an operator and a means for acquiring a second time lag which is a time by which the fetched audio data exhibit silence beginning with the top thereof, and said table updating means updates the contents of said start time table and said end time table based on the fetched first and second time lags.

Claim 12

A video and audio editing system as claimed in claim 7, wherein said time lag inputting means is an instruction inputting apparatus manually operated by an operator who independently inputs time lag information.
