The video camera apparatus obtains a still image sensing signal with high image quality in a progressive scan mode and is capable of recording onto a recording medium by a recording means which performs recording operation corresponding to an interlace scan mode. An image sensing signal read from a CCD image sensorin the interlace scan mode is recorded directly onto a recording medium by a recording/reproducing sectionthrough a camera signal processing circuit, while an image sensing signal read from the CCD image sensorin the progressive scan mode is converted into an interlace scan signal and is then recorded onto a recording medium by the recording/reproducing section

Video camera apparatus using an image sensor

A recording apparatus of the present invention comprises a compressed data processing unit for performing compression processing of second definition data to generate compressed data, a system data generating unit for generating system data including at least time code, an extended track number generating unit for generating extended track number on the basis of inputted second definition data, a memory unit for storing compressed data and system data, a read-out unit for reading out compressed data and system data which are stored in the memory unit, a control unit for controlling the read-out unit so as to read out, at a predetermined timing, the compressed data and the system data which are stored in the memory unit on the basis of the extended track number, and a recording unit for recording, into second sector, compressed data which has been read out from the read-out unit, and for recording, into third sector, along with extended track number, system data which has been read out by the read-out unit.

Recording apparatus and method

Audio signals and video signals are recorded as follows. Three video PES packets, each being formed of one video frame, are combined to form a video editing unit. Then, the video editing unit and the associated audio editing unit are alternately disposed on a magnetic tape. The recorded PES packets are output as a TS as follows. A STC is initialized, and then, PSI packets of a PAT and a PMT are output. TS packets specially used for a PCR for storing the STC are then output at certain intervals. Subsequently, video PES packets are converted into TSs, and the output of the video TSs is started while synchronizing a time obtained by subtracting vbv_delay from the first I-picture DTS with the STC. Audio PES packets are converted into TSs, and the output of the audio TSs is started while synchronizing a time obtained by subtracting the start up delay from the first frame with the STC. Data streams are recorded in the following manner. The three MSBs of a sync block (SB) header indicate the type of data to be recorded in the following data area. If the data type is PES-VIDEO or PES-AUDIO, a full/partial flag is recorded in the fourth MSB of the SB header. In the subsequent four LSBs, the continuity count value representing the continuity of the same type of SBs is recorded.

Recording apparatus and method, playback apparatus and method, and recording medium therefor

A magnetic-tape recording apparatus records digital data on a magnetic tape by a rotating head. It includes a first obtaining device for obtaining predetermined-unit video data; a second obtaining device for obtaining audio data corresponding to the predetermined-unit video data; a synthesizing device for synthesizing the predetermined-unit video data and the audio data corresponding to the predetermined-unit video data such that they are continuous on a track in the magnetic tape without any space disposed therebetween; and a sending device for sending data synthesized by the synthesizing device to the rotating head in order to record the data on the magnetic tape.

Video camera apparatus

An imaging apparatus can obtain a high quality still picture imaging signal in the all pixels read out mode and output it by means of an output processing means adapted to the interlaced read out mode. The imaging signal read out from a CCD image sensor in the interlaced read out mode is directly supplied to a DV recording/reproducing processing section by way of a camera signal processing circuit . The imaging signal read out from said CCD image sensor in the apparatus is converted into an interlaced signal by a scan conversion section A, which is then supplied to the DV recording/reproducing processing section
