`ABSTRACT
`(57)
`A digital content reproducing apparatus is provided with a
`plurality of user operation interfaces, e.g., a linear content
`operation panel and an interactive content operation panel,
`a data monitor unit monitors information on digital contents,
`and upon occurrence of a change, the plurality of user
`operation panels are automatically and exclusively dis
`played in an operation panel display area. Accordingly, only
`usable operation keys can be displayed, user operation
`learning time can be shortened, since the panel rendering
`area is made Small, a mouse motion distance can be short
`ened, and easy to use can be improved. Further, since the
`panel rendering area is made Small, the image display area
`can be made relatively large.

`
`CROSS-REFERENCE TO RELATED
`APPLICATION
`0001. This application relates to and claims priority from
`Japanese Patent Application No. 2005-248576, filed on Aug.
`30, 2005, the entire disclosure of which is incorporated
`herein by reference.
`
`BACKGROUND OF THE INVENTION
`0002 The present invention relates to image rendering
`techniques for an apparatus which reproduces digital con
`tents multiplexing a plurality of contents having different
`information, and more particularly to image rendering tech
`niques for reproduction control of digital contents by using
`user operation interfaces.
`0003. A conventional digital broadcasting compatible
`HDD/DVD decoder which is a digital content reproduction
`apparatus requires, in addition to channel tuning, reproduc
`tion control keys for linear contents such as video and audio,
`the keys including “reproduce”, “stop”, “fast forward”, “fast
`backward”, “temporary stop' and other operation keys. The
`apparatus further requires “up”, “down”, “right”, “left'.
`“decide' and four-color keys for operation control of data
`broadcasting. In order to deal with all functions, a number of
`remote keys are required. It takes learning time in order for
`a user master an operation method, or there is an issue of not
`easy to use.
`0004 As described in JP-A-2005-73022, there is known
`a broadcast receiving apparatus which provides a user with
`illumination of a usable key of a remote controller in
`accordance with information on digital contents. Typical
`apparatus which perform reproduction control by graphical
`user interface (GUI) digital include a digital broadcasting
`compatible personal computer and a DVD reproduction
`compatible personal computer. In these apparatus, reproduc
`tion keys for linear contents and interactive contents are
`displayed on a screen and unusable keys are disabled so that
`it is possible to improve user easy to use performance.
`However, in order to display all keys, a large panel rendering
`area is required. Since linear contents and interactive con
`tents are multiplexed and transmitted for digital broadcast
`ing, these contents are also recorded in a multiplexed state.
`
`SUMMARY OF THE INVENTION
`0005. The apparatus described in JP-A-2005-73022 is
`required to mount all keys so that a remote controller having
`a large area is used. Similarly, the apparatus using GUI is
`also required to display all keys so that a wide operation
`panel rendering area is used.
`0006 Information on data added digital broadcasting
`includes up-to-date news, weather forecast and the like.
`There arises an issue of a lapse of an appreciation term,
`when reproduction is made.
`0007. It is therefore an object of the present invention to
`display automatically only usable operation keys in accor
`dance with information on digital contents. Accordingly, a
`user operation learning time can be shortened, since the
`panel rendering area is made Small, a mouse motion distance
`can be shortened, and an easy to use performance can be
`
`improved. It is an object of the present invention to provide
`a digital content reproduction apparatus capable of having a
`relatively large image display area by making Small a panel
`rendering area. It is another object of the present invention
`to provide a digital content reproduction apparatus capable
`of reproduction within an appreciation term by monitoring
`information on digital contents.
`0008 According to the digital content reproduction appa
`ratus of the present invention, a plurality of user operation
`interfaces of the same size are provided, information on
`digital contents is monitored, and upon occurrence of a
`change in the information, the user operation interfaces are
`automatically and exclusively displayed in the same panel
`rendering area so that only usable operation keys can be
`displayed. Information on digital contents is monitored and
`display is controlled in accordance with digital content
`attributes.
`0009. According to the present invention, a plurality of
`user operation interfaces of the same size are provided,
`information on digital contents is monitored, and upon
`occurrence of a change in the information, the user operation
`interfaces are automatically and exclusively displayed in the
`same panel rendering area so that only usable operation keys
`can be displayed and a user operation learning time can be
`shortened.
`0010. According to the present invention, since the panel
`rendering area is made Small, a mouse motion distance can
`be shortened so that a user easy to use performance can be
`improved.
`0011. According to the present invention, since the panel
`rendering area is made Small, the image display area can be
`made relatively large.
`0012. According to the present invention, only informa
`tion within an appreciation term can be presented by con
`trolling the display state in accordance with information on
`digital contents.
`0013. Other objects, features and advantages of the
`invention will become apparent from the following descrip
`tion of the embodiments of the invention taken in conjunc
`tion with the accompanying drawings.

`
`DESCRIPTION OF THE EMBODIMENTS
`0027 Embodiments of the present invention will be
`described in detail with reference to the accompanying
`drawings.
`0028 FIG. 1 is a diagram showing the structure of a
`digital content reproduction apparatus according to the
`embodiment of the present invention.
`0029 Referring to FIG. 1, the digital content reproduc
`tion apparatus records broadcast data received at a broadcast
`receiving unit 1 in a data record unit 3 with involvement of
`a data input/output control unit 2. The data input/output
`control unit 2 reads data from the data record unit 3 and
`Supplies the read data via a data extraction (demultiplex)
`unit 4 to a content decode unit 6 which decodes the supplied
`data and sends the decoded data to an image rendering unit
`7. A data monitor unit 5 always monitors information on
`digital contents in the data extraction unit 4, and in accor
`dance with a change in the information, instructs the image
`rendering unit 7 to perform rendering of an user operation
`interface corresponding to the information on the contents.
`The decoded contents and the user operation interface are
`Superposed and output as image data by the image rendering
`unit 7. A user input to the displayed user operation interface
`from a mouse, a keyboard or a remote controller is sent to
`a user operation input unit 8 which transfers the user
`operation information to a system control unit 9. In accor
`dance with the user operation information, the system con
`trol unit 9 controls the broadcast receiving unit 1, data
`input/output control unit 2, data extraction unit 4, content
`decode unit 6 and image rendering unit 7.
`0030) Next, description will be made on the user opera
`tion interface during digital broadcast reproduction.
`0031
`FIGS. 2 to 4 show image display states during
`digital broadcast reproduction. A monitor Al has a content
`display area A2 and an operation panel display area A3.
`During reproduction of linear contents such as moving
`image contents, a linear content operation panel A4 is
`displayed in the operation panel display area A3, the linear
`
`content operation panel providing functions of reproduce,
`stop, temporary stop, fast forward, fast backward, previous
`skip, next skip and the like.
`0032. During reproduction of interactive contents such as
`data broadcast contents, an interactive content operation
`panel A5 is displayed in the operation panel display area A3,
`the interactive content operation panel providing functions
`of numerical keys from 0 to 9, up/down/right/left keys, a
`decide key, blue/red/green/yellow keys and other keys.
`0033. The linear content operation panel A4 and interac
`tive content operation panel AS are displayed exclusively
`and are not displayed at the same time. The functions
`provided by the linear content operation panel A4 and
`interactive content operation panel A5 are not limited to
`those described above, but the functions may be increased or
`decreased in accordance with the apparatus function.
`0034) Next, by taking Japanese terrestrial digital broad
`casting as an example, description will be made on a specific
`digital content monitoring method.
`0035 TV type services, data broadcasting services and
`data added TV services are defined for Japanese terrestrial
`digital broadcasting (Association of Radio Industries and
`Businesses: Terrestrial Digital Television Broadcasting
`Operational Guideline TR-B14). Program specific informa
`tion (PSI) on digital broadcasting contains a program map
`table (PMT). PMT contains a data encode descriptor which
`contains an auto Start flag.
`0036). In data added TV services, if the auto start flag is
`'1', data broadcasting is automatically displayed, whereas if
`it is "O. data broadcasting is displayed upon instruction
`from a user. The data monitor unit monitors the auto start
`flag, and when the flag becomes “1, the interactive content
`operation panel A5 is displayed, and when the flat becomes
`“0”, the linear content operation panel A4 is displayed.
`0037. In this embodiment, the linear content operation
`panel and interactive content operation panel are provided,
`information on digital contents is monitored, and upon
`occurrence of a change in the information, the panels are
`automatically and exclusively displayed in the operation
`panel display area A3 of the same panel rendering area size.
`Accordingly, only usable operation keys can be displayed, a
`user operation learning time can be shortened, since the
`panel rendering area is made Small, a mouse motion distance
`can be shortened, and an easy to use performance can be
`improved. Further, since the panel rendering area is made
`Small, the image display area can be made relatively large.
`0038. In this embodiment, although terrestrial digital
`broadcasting has been described, the embodiment is also
`used for reproduction of other digital contents. Also in this
`case, the operation panel can be switched automatically by
`monitoring the content Switching flag.
`0039 FIG. 5 is a diagram showing the structure of a
`digital content reproduction apparatus according to another
`embodiment of the present invention. Description will be
`made on only different points from the description described
`So far.
`0040. In the above description, although data is supplied
`to the apparatus by using broadcasting waves, in this
`embodiment, digital content services via a network B1 are
`assumed. In this case, data can be acquired via a network

`description, although a single monitor is used which has
`both the content display area and operation panel display
`area, in this embodiment, a first monitor A6 has a content
`display area A2 and a second monitor A7 has an operation
`panel display area A3. If a remote controller or the like has
`the operation panel display area A3, the number of keys of
`the remote controller can be reduced. FIG. 9 is a diagram
`showing the structure of the digital content reproduction
`apparatus of this embodiment.
`0046. A different point from the foregoing description
`resides in that a content rendering unit 7b and an operation
`panel rendering unit 7c are independent. Other points are
`similar to the foregoing description, and the description
`thereof is omitted. FIGS. 10 to 12 show the structures that
`the content rendering unit 7b and operation panel rendering
`unit 7c are made independent as different from the foregoing
`description. Other points are similar to the foregoing
`description, and the description thereof is omitted.
`0047 FIGS. 10 to 12 are similar to those figures
`described above. In the foregoing description, although the
`data monitor unit monitors the auto start flag, in this
`embodiment, attributes of digital contents are recorded and
`a data broadcasting descriptive language BML (Broadcast
`Markup Language) is analyzed.
`
`0048 FIG. 13 shows examples of the attributes and
`language analysis results. Information on data added digital
`broadcasting includes up-to-date news, weather forecast and
`the like. These contents have a nature of an appreciation
`term and it is difficult to consider that these contents are
`referred to after, e.g., one month. In this embodiment,
`therefore, a content appreciation term is set beforehand in
`accordance with record days and times and information on
`the contents. If contents are within the appreciation term,
`data broadcasting is not displayed even if the auto start flag
`is “1”, but the linear content operation panel is displayed. If
`the contents are within the appreciation term and a user does
`not still view the contents, the data broadcasting is auto
`matically displayed even if the auto start flag is “0” and the
`interactive content operation panel is displayed. Only new
`information can be presented for viewing, by controlling the
`display state in accordance with information on digital
`COntentS.
`0049. It should be further understood by those skilled in
`the art that although the foregoing description has been
`made on embodiments of the invention, the invention is not
`limited thereto and various changes and modifications may
`be made without departing from the spirit of the invention
`and the scope of the appended claims.
