Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a method of presenting A/V
data and contents data recorded on an interactive recording medium
and contents data provided by a contents providing server connected
through the Internet.
[0003] 1. Description of the Related Art
[0004] High-density recording media such as optical disks capable
of recording large amounts of data are being widely used. The DVD
(digital versatile disc), which is an optical recording medium
capable of recording large amounts of high-quality digital video
and audio data, is one example of these high-density recording
media.
[0005] The DVD includes a data stream recording area in which
digital A/V data streams are recorded and a navigation data
recording area in which navigation data required for playback
control of the A/V data is recorded.
[0006] When a DVD is loaded into a DVD reproducing apparatus, the
DVD reproducing apparatus first reads the navigation data recorded
in the navigation data recording area and stores the navigation
data in an internal memory. The DVD reproducing apparatus then
begins reproduction of the A/V data recorded in the data stream
recording area using the stored navigation data, thereby providing
various functions of the DVD to a viewer.
[0007] The development of new interactive DVDs is being progressing
rapidly. Unlike the DVD, the interactive DVD (I-DVD) contains
additional contents data, which is detailed information about A/V
data recorded thereon, and provides the contents data through a
user interface. The contents data may be recorded on the I-DVD as
data files such as html files.
[0008] In addition, a method for obtaining additional contents data
from a contents providing server connected through the Internet and
presenting the contents data while A/V data and contents data
recorded on the I-DVD are reproduced is under development. However,
an effective method for presenting the contents data appropriately
according to the attributes is not yet available.
SUMMARY OF THE INVENTION
[0009] It is an object of the present invention to provide a method
of presenting auxiliary contents data recorded on an interactive
recording medium or contents data provided by an external contents
providing server appropriately according to the attributes using
attribute information recorded on the interactive recording medium
or provided by the contents providing server.
[0010] The method of reproducing an interactive recording medium in
a reproducing apparatus in accordance with the present invention
comprises the steps of (a) checking attribute information for
auxiliary contents data of A/V data recorded on the interactive
recording medium and (b) determining a presentation method for the
auxiliary contents data based on the attribute information and
presenting the auxiliary contents data accordingly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0019] In order that the invention may be fully understood,
preferred embodiments thereof will now be described with reference
to the accompanying drawings.
[0020] FIG. 1 illustrates an interactive optical disk reproducing
apparatus in which the present invention may be advantageously
embodied. The reproducing apparatus 100 comprises an optical pickup
11, an IDVD system 12, a microprocessor 13, a buffer memory 14, and
an Internet interface 15 through which the apparatus 100 is
connected to a contents providing server 300.
[0021] The IDVD system 12 includes a DVD engine for reproducing A/V
data recorded on an I-DVD 10 and an enhanced navigation (ENAV)
engine for reproducing contents data provided by the contents
providing server 300 or contents data recorded on the I-DVD 10.
[0022] The IDVD system 12 outputs the contents data in
synchronization with the A/V data reproduced from the IDVD 10. As
shown in FIG. 1, the reproducing apparatus 100 is connected to the
contents providing server 300 through the Internet interface 15 by
the mutual operations of the microprocessor 13 and the ENAV engine
included in the IDVD system 12.
[0023] ENAV contents data, which is additional contents data
associated with the A/V data reproduced from the I-DVD 10, is
downloaded from the contents providing server 300 and then
temporarily stored in the buffer memory 14. The buffer memory 14
can be logically divided into a first buffer (buffer 1) and a
second buffer (buffer 2).
[0024] The ENAV engine in the IDVD system 12 outputs the A/V data
from the I-DVD 10 in synchronization with the ENAV contents data
from the I-DVD 10 or outputs the A/V data from the I-DVD 10 in
synchronization with the ENAV contents downloaded from the contents
providing server 300.
[0025] The ENAV contents data recorded on the I-DVD 10 is organized
into a plurality of data files and ENAV navigation information for
reproducing the data files in synchronization with A/V data may
also be recorded thereon. The contents providing server 300
provides various ENAV contents data associated with the A/V data
recorded on the I-DVD 10 as a plurality of data files and provides
ENAV navigation information for reproducing the data files in
synchronization with A/V data. The navigation information may be
provided all at once or may be divided into a plurality of pieces
and provided one by one when needed.
[0026] As shown in FIG. 2, for example, a title of the I-DVD 10 is
organized into a plurality of individual chapters (Chapter#1,
Chapter#2, . . . ) and one or more data files (File#1, File#2, . .
. ) corresponding to each of the chapters are organized as an ENAV
unit. Navigation information for managing the data files included
in the ENAV unit is provided as ENAV unit information
(ENAV_Unit_Info).
[0027] The multiple pieces of ENAV unit information
(ENAV_Unit#1_Info, ENAV_Unit#2_Info, . . . ) are defined as a
linked list and transmitted along with the ENAV contents data files
or transmitted before the ENAV contents data files are sent.
[0028] As shown in FIG. 3, the ENAV unit information includes file
names of data files included in the associated ENAV unit (File(s)
Name), addresses of the data files in the contents providing server
300 (File(s) Address), and attribute information for the data files
(File(s) Attribute).
[0029] For example, the `File(s) Attribute` field for File#2
includes the information that `Type=Non_Square` indicating the
image type and `Ratio=16:9` indicating the aspect ratio and the
`File(s) Attribute` field for File#3 includes the information that
`Type=Square` and `Ratio=4:3`.
[0030] The microprocessor 13 controls presentation of the data
files using the fields of `File(s) Name` and `File(s) Address`
included in the ENAV unit information so that the data files
reproduced by the ENAV engine may be presented in synchronization
with the chapters of the AV data stream reproduced by the DVD
engine.
[0031] Also, the microprocessor 13 controls the image of the
contents data reproduced by the ENAV engine to be presented with an
appropriate image type and aspect ratio using the image type and
aspect ratio information of the `File(s) Attribute` field included
in the ENAV unit information.
[0032] Instead of recording the attribute information explicitly,
the attribute information may be implicitly recorded such that it
can be identified indirectly from the names of the data files. As
shown in FIG. 4, for example, naming File#1 `File#1_S_R.sub.--4`
makes it possible to identify the information that `Type=Square`
and `Ratio=4:3` for File#1.
[0033] Likewise, the image type and aspect ratio of File#2 may be
identified by naming File#2 `File#2_NS_R16`, which indicates that
`Type=Non_Square` and `Ratio=16:9`. The microprocessor 13
determines the image type and aspect ratio of a data file from its
name and controls the image of the contents data reproduced by the
ENAV engine to be presented with the appropriate attributes in
conjunction with the A/V data reproduced from the I-DVD 10.
[0034] The attribute information may be included in meta tag
information as shown in FIG. 5. For example, if the contents data
files are html files, the image type and aspect ratio for an html
data file may be recorded in the meta tag information included in
the header area thereof.
[0035] The attribute information of `image=Square.sub.--4:3` is
added to the meta tag information included in the header area of
File#1 to indicate that `Type=Square` and `Ratio=4:3`. The
attribute information of `image=Non_Square.sub.--16:9` is added to
the meta tag information included in the header area of File#2 to
indicate that `Type=Non_Square` and `Ratio=16:9`.
[0036] The microprocessor 13 determines the image type and aspect
ratio of a data file from the meta tag information and controls the
image of the contents data reproduced by the ENAV engine to be
presented with the appropriate attributes in conjunction with the
A/V data reproduced from the I-DVD 10.
[0037] The attribute information may be included in tag information
of a general data file as shown in FIG. 6. For example, the
attribute information may be added to tag information, which is
positioned at the head or tail of the data file, as image tag
information.
[0038] Attribute information for File#1 indicating that
`Type=Square` and `Ratio=4:3` is added to the tag information
positioned at the head of File#1. Attribute information for File#2
indicating that `Type=Non_Square` and `Ratio=16:9` is added to the
tag information positioned at the tail of File#2.
[0039] The microprocessor 13 determines the image type and aspect
ratio of a data file from the tag information and controls the
image of the contents data reproduced by the ENAV engine to be
presented with the appropriate attributes in conjunction with the
A/V data reproduced from the I-DVD 10.
[0040] By the aforementioned procedure, the interactive optical
disk reproducing apparatus 100 can present ENAV contents data in
synchronization with A/V data reproduced from the I-DVD 10 with an
image type and aspect ratio appropriate for the contents data.
[0041] The attribute information may include other attributes as
well as the image type and aspect ratio of contents data.
[0042] The method of presenting auxiliary data for an interactive
recording medium in accordance with the present invention allows
auxiliary contents data for A/V data recorded on the interactive
recording medium to be presented appropriately according to the
attributes of the contents data.
[0043] While the invention has been disclosed with respect to a
limited number of embodiments, those skilled in the art, having the
benefit of this disclosure, will appreciate numerous modifications
and variations therefrom. It is intended that all such
modifications and variations fall within the spirit and scope of
the invention.
