PROBLEM TO BE SOLVED: To make a user grasp the present reproduction position even though commercials are skipped and reproduced when an optical disk on which a television broadcast signal consisting of a file for program main edditing constituted by inserting a file for commercial in the halfway of the file is recorded, is reproduced. SOLUTION: A CPU 20 copies TOC data recorded on an optical disk 1 via a code buffer 15 and a code buffer 24 into a memory for TOC 21 to store them as TOC information. Moreover, it produces index information by an index producing part 23 according to a command for example, a commercial skipping mode or the like from a user via an operating part 31 by referring the memory for TOC 21 via a control part 22 to transmit them to an index mixing part 18 which mixes the index information to an NTSC signal from an NTSC converting part 17 to supply the mixed signal to a monitoring device 19 which displays the index information together with a video signal.

PROBLEM TO BE SOLVED: To simply set a recording and reproducing position in a recording and reproducing apparatus which comprises a simultaneous recording and reproducing function, an overwrite recording function or the like. SOLUTION: As a recording medium, a recording medium which can be random-accessed such as a magnetic disk 5a or the like is provided. A table-of- contents(TOC) region is formed on the magnetic disk 5a, and information data on a recording data or the like regarding a recorded title is recorded. When the magnetic disk 5a is placed, the information data is read out so as to be stored in an information-system memory 16, and it is supplied to a system controller 10 as required. When a reservation is set, the system controller 10 controls a display output part 12 on the basis of the information data, and a reservation setting screen or the like which contains the recording state display of the magnetic disk 5a is displayed via an image output device such as a television receiver or the like. Data which is set by a user by referring to the display is controlled by the information-system memory 15 so as to be recorded on the magnetic disk 5a at a prescribed timing.
Abstract:
PROBLEM TO BE SOLVED: To attain simply a synchronization of a video and an audio by controlling delay time of the video within one frame, calculating the time information of the video and audio, multiplying this time information together with a video and an audio signals, separating the video and audio signal and the time information from a multiplex signal recorded or transmitted and synchronizing the video and the audio, on the basis of the separated time information. SOLUTION: That a delay time of a video signal from an input of a frame synchronizer 14 to an output ranges 0 to 1 frame means that a delay time between an audio signal inputted and the video signal outputted from the frame synchronizer 14 also ranges 0 to 1 frame. Before multiplexing time audio information A-PTS by a multiplexer MUX 19, time dVFR-int for one frame of an internal reference synchronism is added to the time information A-PTS of audio through an adder inside a microcomputer 11. Thus, the delay time between the audio signal and the video signal is in a ranges of -1 to 0 frame on a time stamp.

CONSTITUTION: A liquid crystal display monitor 2 is separated from a video camera main body 1 and while the liquid crystal monitor 2 is separated, an image pickup image signal from the video camera main body 1 or a reproduced image signal being an infrared ray signal is received by the liquid crystal monitor 2 and displayed on a monitor screen or a remote controller is built in the liquid crystal monitor 2 and a remote command signal being an infrared ray signal from the remote controller is received by the video camera main body 1 to control the drive of the video camera.
Abstract:
PROBLEM TO BE SOLVED: To generate a search image with which a summary of recorded contents can be obtained and a video signal can be searched when video signals are recorded on a recording medium. SOLUTION: A video signal recording apparatus 1 records an input video signal on a recording medium 15. At such a time, an additional information detection circuit 16 detects additional information included in a sub code of the input video signal or in a vertical blanking interval. A feature quantity detection circuit 17 detects a feature quantity indicating an amount of motion of the video signal or presence of telop. On the basis of the additional information and feature quantity, a system controller 20 detects an image to be displayed as a search picture. When detecting such an image, the system controller 20 supplies an identification signal indicative of the detected image to a recording processing circuit 14 and the recording processing circuit 14 records the identification signal in a sub code or the like, for example.

PROBLEM TO BE SOLVED: To provide the encoding device of a moving image signal by which scale reduction and speeding up of a circuit for acquiring information necessary for computation of encoding difficulty are attained. SOLUTION: In a first path, an input digital stream signal is recorded in a mass storage device 13; whereas the information necessary for computing encoding difficulty for each frame is generated from the digital stream signal, and encoding difficulty information is created and recorded in the mass storage device 13. In a second path, the digital stream signal and pieces of encoding difficulty information for each frame are read from the mass storage device 13, the digital stream signal is decoded; while the bit rate to be assigned for encoding of the frames is computed on the basis of the encoding difficulty information, and the decoded signal is encoded in accordance with the computed bit rate.
