Abstract
Abstract The present invention applies to a video tape recorder that records HDTV (High Definition Television) video signals, in particular, onto a magnetic tape, and records at least reproduction standard management information ETN in the order of pictures of video data to be reproduced and output in a main sector, and in the order of pictures of compressed video data in a subcode sector. Search data is recorded on the basis of time management information of video data at the time of decoding, while display data is recorded on the basis of time management information on reproduction and output of video data.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
219 words
A video tape recorder that sequentially forms
recording tracks aslant on a magnetic tape and records video
data, audio data, and auxiliary data related to the video
data and the audio data onto the magnetic tape, comprising: data compressing means for compressing the video data
and the audio data to generate compressed video data and
compressed audio data; pack unit generating means for generating a pack unit
by forming compressed video data into a block for each
predetermined number of pictures and combining the
compressed video data of the block, the compressed audio
data corresponding thereto, and the auxiliary data
corresponding thereto; and a recording system that allocates data of the pack unit
to a main sector and allocates the auxiliary data of the
pack unit to a subcode sector to sequentially form recording
tracks based on the main sector and the subcode sector, wherein the auxiliary data of the main sector includes at least reproduction standard management information,
which corresponds to time management information of the
video data in a decoding mode and which is disposed in the
order of pictures of the video data, and the auxiliary data of the subcode sector includes at least the reproduction standard management
information and picture type information that are disposed
in the order of pictures of the compressed video data.
Claim 2
Dependent Claim
81 words
The video tape recorder according to Claim 1, wherein the auxiliary data of the main sector includes, in addition to the reproduction standard management
information, time information of the video data and/or the
audio data, which is disposed in the order of pictures of
the video data, and the auxiliary data of the subcode sector includes time information of the video data and/or the audio
data, which is disposed in the order corresponding to the
auxiliary data of the main sector.
Claim 3
Dependent Claim
134 words
The video tape recorder according to Claim 1,
comprising: search data generating means for generating search data
from picture data by encoding within a frame in the video
data; and auxiliary data generating means for generating
auxiliary data for search related to the search data, wherein the pack unit generating means further combines
the search data and the auxiliary data to generate the pack
unit, of the auxiliary data of the search data, search data of the video data recorded on the magnetic
tape is recorded on the basis of the time management
information of the video data in the decoding mode, and display data to be displayed with an image based on the
search data is recorded on the basis of the time management
information on reproduction and output of the video data.
Claim 4
Dependent Claim
27 words
The video tape recorder according to Claim 3, wherein
the search data is tape position information indicating a position where
the corresponding video data has been recorded.
Claim 5
Dependent Claim
24 words
The video tape recorder according to Claim 3, wherein
the search data is management information on a reproduction standard of
the corresponding video data.
Claim 6
Dependent Claim
20 words
The video tape recorder according to Claim 3, wherein
the display data is time information of the corresponding video data.
Claim 7
Dependent Claim
220 words
A recording method for sequentially forming recording
tracks aslant on a magnetic tape and recording video data,
audio data, and auxiliary data related to the video data and
the audio data onto the magnetic tape, comprising: a data compressing step for compressing the video data
and the audio data to generate compressed video data and
compressed audio data; a pack unit generating step for generating a pack unit
by forming compressed video data into a block for each
predetermined number of pictures and combining the
compressed video data of the block, the compressed audio
data corresponding thereto, and the auxiliary data
corresponding thereto; and a recording step for allocating data of the pack unit
to a main sector and allocating the auxiliary data of the
pack unit to a subcode sector to sequentially form recording
tracks based on the main sector and the subcode sector, wherein the auxiliary data of the main sector includes at least reproduction standard management information,
which corresponds to time management information of the
video data in a decoding mode and which is disposed in the
order of pictures of the video data, and the auxiliary data of the subcode sector includes at least the reproduction standard management
information and picture type information that are disposed
in the order of pictures of the compressed video data.
Claim 8
Dependent Claim
80 words
The recording method according to Claim 7, wherein the auxiliary data of the main sector includes, in addition to the reproduction standard management
information, time information of the video data and/or the
audio data, which is disposed in the order of pictures of
the video data, and the auxiliary data of the subcode sector includes time information of the video data and/or the audio
data, which is disposed in the order corresponding to the
auxiliary data of the main sector.
