Abstract: A camera head unit including an image sensor configured to generate an image signal, a main unit configured to perform a signal process to the image signal, and first and second cables are included. Further, a determining section configured to determine whether a connection state is in a first connection state in which the camera head unit and the main unit are connected with each other via a first cable without a second cable or a second connection state in which the camera head unit and the main unit are connected with each other via the first cable and the second cable, and a transmission section configured to transmit the image signal between the camera head unit and the main unit at least via the first cable according to a determination result determined by the determining section are included.

Abstract: A main unit and a camera head unit including an image sensor and being detachably attachable to the main unit are included. Further, a first cable including a first connector section and a second connector section and being capable of connecting between the camera head unit and the main unit, and a second cable including a third connector section and a fourth connector section and being capable of connecting between the camera head unit and the main unit via the second cable and the first cable connected with the second cable are included. In addition, the second connector section and the fourth connector section have a same structure.

Abstract: A digital audio signal processing apparatus for creating coded edited data by insertion of second coded audio data coded in block units not synchronized with frames and fields into first coded audio data coded in block units also not synchronized with the frames and the fields at a request made by a command signal synchronized with the frames or the fields comprises coding means for creating the first and second coded audio data, and switching means for receiving the first and second coded audio data whereby selective switching of the first coded audio data and the second coded audio data from one to another is carried out at a location selected among a position specified by the command signal and positions before or after the specified position when the selected location coincides with a boundary between two consecutive coded blocks of the first and second coded audio data.

Abstract: A system for performing insertion editing on the audio portion of an audio-visual signal; wherein the video portion of the signal is coded in field/frame units, and the audio portion of the signal is coded in block units which are not synchronized with the field/frame units. The system allows the block units of audio to be insertion edited according to a command that is synchronized with the field/frame units of video--despite the non-synchronous relationship between the block and field/frame units. Audio editing is implemented through a switching scheme that adjusts the audio insertion begin point and end point to account for differences between the block unit and field/frame unit boundaries.

Abstract: Methods and apparatus are provided for changing the repetition rate of image data. A correlation value representing similarity between fields or frames of the image data is produced and one or more fields or frames are added to or subtracted from the image data selectively based on the first correlation value to produce output image data having a repetition rate different from an initial repetition rate of the image data. In other aspects, methods and apparatus for detecting that a sequence of field or frame image data intervals represent a still image are provided which compare direct current components of corresponding discrete cosine transformed data blocks of sequential image data intervals to determine a number thereof which are equivalent, and determine that the image data intervals represent a still image when the sum number exceeds a predetermined threshold.
