BACKGROUND1. Field
The present invention relates to display devices, and more particularly, to a method of displaying recorded material and a display device using the same.
2. Background
A contemporary display device, such as a television receiver provided with a personal video recorder (PVR), enables the storage (i.e., recording) and playback (i.e., reproduction) of received signals, e.g., received television broadcasts and other video-based content, according to a user selection from a recording item list, which may be displayed using on-screen display (OSD) data. Such a recording item list can be viewed as an OSD menu including selectable icons, for example, in the form of titles and/or thumbnails, providing a user with means to designate for playback a specific recording item of the list.
Meanwhile, the display device may be further provided with a limited preview mode enabling a user to recognize content of a designated (highlighted) recording item. A recording item is typically designated by manipulating a curser to navigate the displayed recording item list, for example, to select a specific recording item for playback. In the preview mode, a thumbnail or other sample image corresponding to each menu item (e.g., title) may be displayed via a corresponding preview window. That is, the OSD menu of the recording item list uses a single preview window to display a sample image of the corresponding recording item when highlighted for playback execution.
For improved user recognition of the selected recording item, the single preview window may display more than one such thumbnail or sample image. For example, a plurality of thumbnails may appear in the preview window through the use of a type of a revolving display, where a predetermined viewing time period is allotted for each thumbnail before the next thumbnail is likewise displayed for a similar time period. In other words, prior to playback execution, a single preview window may display a predetermined set of sample images, one by one, in correspondence to any selected one of the recording items. Such a revolving display may be initiated for a default menu item (e.g., the latest recording item) in the absence of a user selection from the recording item list or upon such recording item selection by the user.
In a contemporary display device as described above, however, a user has difficulty in recognizing the overall contents of corresponding recorded material at a glance. Also, after selection of a specific recording item for playback, in the event that there may be a favorite or otherwise specially desired portion of the selected recording item, it may take the user considerable time to search for a corresponding recording point enabling more immediate playback.
Accordingly, the present invention is directed to a method of displaying recorded material and display apparatus using the same that substantially obviates one or more problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a method of displaying recorded material and display apparatus using the same, which facilitates user recognition of the contents of selected recorded material prior to its reproduction (playback).
Another object of the present invention is to provide a method of displaying recorded material and display apparatus using the same, which facilitates user recognition of the contents of all recorded material available for reproduction (playback).
Another object of the present invention is to provide a method of displaying recorded material and display apparatus using the same, which facilitates the recognition and designation for playback of a specific recording position of recorded material selected (designated) by a user.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these objects and other advantages in accordance with the purpose of the invention, as embodied and broadly described herein, there is provided a method of displaying recorded material in a display device. The method comprises displaying a recording item list having a plurality of recording items; and simultaneously displaying, in response to a user selection of a specific recording item, a plurality of sample images corresponding to the selected recording item via a corresponding plurality of preview windows.
According to another aspect of the present invention, there is provided a display device comprising a personal video recorder (PVR) unit for storing content of at least one recording item of a recording item list; a PVR controller for extracting a plurality of sample images corresponding to each stored recording item; and a display module including a screen for displaying the recording item list in response to a recording item list request and for simultaneously displaying, in response to a user selection of a specific recording item, the extracted sample images corresponding to the selected recording item via a corresponding plurality of preview windows.
It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiment(s) of the invention and together with the description serve to explain the principles of the invention. In the drawings:
According to the present invention, a plurality of preview windows for a single item of a recording item list is employed, for example, as part of an OSD menu. The preview windows of the present invention occupy adjacent areas of the same screen and respectively display N sample images (e.g., thumbnails) of one selected recording item in association with another identifying feature (e.g., a program title) of the selected item. By thus displaying the plurality of sample images simultaneously, a user is able to recognize the overall contents of recorded material at a glance and may be further provided with time information corresponding to a position of any one or all of the sample images. In particular, without playing or viewing a selection of recorded material in its entirety, the N sample images of a selected (highlighted) recording item are simultaneously displayed via the N preview windows, respectively. The set of N sample images, which may include still images, thumbnails, or sample moving pictures, may represent equally spaced divisions of an item of the recorded material. For example, the recording length (run time) of a selected recording item may be divided by a number N, i.e., a value set by the user or determined as a default value, where a representative sample image is extracted from the recorded material in correspondence to each interval. Accordingly, a set of sample images may be simultaneously displayed via the plural preview windows, respectively, with time information of each interval being displayed in association with the corresponding sample image.
Referring to
Meanwhile, a display device (e.g., a television receiver) according to the present invention, which includes a personal video recorder, is typically configured to receive a video input signal (VIDEO IN) including content to be recorded in the personal video recorder. That is, the display device according to the present invention may be provided with means to receive and record additional video content, i.e., in addition to that which may already be stored in the storage medium 104b. Here, the storage medium 104b of the display device according to the present invention may be provided internally or may be connected externally as an externally disposed or remotely accessible (e.g., via the Internet) storage device. As such, the display device of the present invention may be supplied with video data as a transport stream (TS) output from the storage medium 104b or input to the PVR controller 103 via its video input.
For the video input to a display device of the present invention, an antenna and tuner arrangement (not shown) may be provided to selectively receive terrestrial television broadcast signals and may be further or alternatively provided with an external signal input port (not shown) to receive a video input signal via a cable connection to an external source or service. Such a tuner may be an analog broadcast signal tuner or a digital broadcast signal tuner, and the cable connection signal may likewise correspond to an analog or digital television signal. In addition to broadcast signal reception as above, one or more multimedia peripherals, such as a digital video disc player, videotape recorder, or other external player (not shown), may be variously connected to supply a video input signal according to user requests.
The PVR controller 103 serves as a central processing unit of the display device according the present invention and controls the PVR unit 104 in response to key signal data provided in accordance with user selections. For instance, the PVR controller 103 provides the PVR unit 104 a thumbnail extraction command in response to a key signal from the user interface and according to system programming. In response to the thumbnail extraction command, which is generated in correspondence to a specific recording item, the PVR unit 104 extracts N (N being a positive integer) corresponding thumbnails at a predetermined time interval and provides the extracted thumbnails to the PVR controller 103 for storage in the system memory 107 together with corresponding title and other identifying information of the specific recording item. It should be appreciated that the thumbnail extraction command may be generated in response to a recording key signal or a specific recording item designation. That is, thumbnail extraction and storage may be performed at the time of originally recording (storing) a video input signal in the storage medium 104b or after designating recorded material of a displayed recording item list, i.e., during an instance of menu display.
Subsequently, the PVR controller 103 uses the extracted N thumbnails to configure recording item OSD data corresponding to the recorded material. In doing so, OSD menu data may be configured for the entire contents of the storage medium 104b, namely, recorded video content available to the display device according to the present invention, and is stored in correspondence to each selectable item of a recording item list to be displayed. Thereafter, in the event of a recording item list key signal input from the user interface 101, which is a user operation to request a generation and display of recorded material information, a user selection can be made as desired from a recording item list comprised of the stored recording item OSD data. As such, the requested display of a current recording item list corresponds to entry of a recording item list mode.
In detail, in a recording item list mode selected by a user, a recording item list is displayed on a screen of the display device to provide the user with a visual indication of all recorded material, that is, video content that has been stored in the personal video recorder and is available for playback using the display device. Using, for example, a curser to first highlight one of the recording items, the user may then select any recording item of the list, but if no specific recording item is selected by the user, the display device may simply highlight a latest recording item, i.e., the last or most recently recorded material among the displayed recording items. The display of a recording item list according to the present invention includes a plurality of sample images for at least one item of the list and preferably a set of sample images for all such items.
In the operation of the above-configured display device, a video input signal is stored in the storage medium 104b, enabling recorded material to be played back by the PVR unit 104. Thereafter, if a user selects via the user interface 101a specific recording item from a displayed recording item list, a key signal for selecting the corresponding recording item is input to the PVR controller 103. In this case, the PVR controller 103 is provided with N thumbnails required for configuring the OSD data of the selected recording item. These thumbnails may be provided from the system memory 107, in accordance with a previous instance of recording item OSD data configuration, or via the PVR interface 104a, i.e., from the storage medium 104b. In the later case, since any display of the N thumbnails of the recording item OSD data requires extraction from the recorded material, there may be some delay in generating the requested recording item list. In any event, the provided thumbnail information is output to the video display processor 105, to be integrated with OSD menu data of a current recording item list and displayed on a screen of the display module 106. In doing so, N thumbnails are displayed via N preview windows, which are collectively arranged with at least one other identifying feature of the selected recording item, for example, its title and/or time information of the thumbnail.
As shown in
Referring to
It should be appreciated that the generation and storage of a recording item list as above may be performed with respect to recorded material already stored in the storage medium 104b and available for playback. That is, the above process may be performed in conjunction with a recording item list mode for enabling a playback operation, for example, as part of an initial step of selecting a recording item for playback. In this case, the video input signal of the display device is in effect being supplied from the storage medium 104b, which may be an externally disposed or remotely accessible storage device. In any event, recording item OSD data configured and stored in accordance with
Referring to
In response to a user selection or highlighting of a specific recording item from a displayed recording item list, i.e., in the recording item list mode, a number (N) of preview windows are simultaneously generated to be displayed in association with the selected recording item, and in each preview window, a corresponding sample image is displayed (S405).
Thus, N thumbnails are simultaneously displayed via N preview windows, such that all the thumbnails are displayed in association with the highlighted item and its at least one identifying feature, e.g., its title. The sample images may include any combination of one or more of a thumbnail, a moving picture, or a still image (screen shot). For example, a series of thumbnails may be appear in the plurality of preview windows, respectively, in correspondence to N intervals of a size (period) determined by an equal division of the recording length of the recorded material. If the sample image is a thumbnail, the thumbnail substantially corresponds to a moving picture or video segment of, say, ten seconds in length, and is in essence a representative image of the moving picture, in which its final scene may appear, and perhaps remain displayed, in the preview window after the video segment has run its length. If the sample image is a moving picture, the moving picture substantially corresponds to a video segment of one interval, such that the recorded material may be fully represented by a simultaneous display of all N sample images via the N preview windows. If the sample image is a still image, a corresponding still image, e.g., an initial frame, of each interval is displayed in each preview window.
Various combinations of the above sample images to be displayed may be devised. For instance, a plurality of still images corresponding to one displayed sample image, such as a thumbnail, may be stored in the system memory 107 (or the storage medium 104b) to enable a selective display of the plurality of stored still images in response to a designation of a specific preview window. Then, at least one still image may be further stored in response to a user selection of at least one of the displayed still images, so that recorded material (video content) may be reproduced from a recording position corresponding to the thus selected at least one still image.
The number (N) of extracted thumbnails, and in turn the count of the preview windows, may be determined in advance by a manufacturer of the display apparatus or may be set and subsequently edited, as desired, by the user. The preview window count may be set, by the manufacturer or by the user, according to a default condition or based on the size (recording length) of the corresponding recording item. Thereafter, to edit the preview window count after selection of a specific recording item as in the steps S403 and S404, the current count may be displayed in a count window 106b enabling a user selection of the preview window count, which determines the number of intervals (equal divisions) of the recorded material. In the absence of a user selection of a specific count, the system programming equally divides the selected recorded material by a default value count. Further, in the absence of any selection of a specific thumbnail of a displayed array of thumbnails, i.e., after recording item highlighting but before playback execution, the N preview windows may each be popped up in turn (one by one) according to an automatic “revolving” thumbnail display cycling through all N thumbnails.
Referring to
Thus, as shown in
Therefore, according to the present invention, a recording item of a recording item list is selected to display a plurality of corresponding thumbnails via a corresponding number of preview windows, which may be set by the user. The plurality of thumbnails are extracted in accordance with a predetermined time interval and displayed together on a screen, which enables a user to recognize at a glance the overall contents of each item of a recording item list. Then, the user may navigate to highlight any one of the preview windows, whereupon the highlighted preview window is popped up and displays the recorded material from a corresponding position of the selected recording item, after which the user may execute a playback operation to reproduce the recorded material from the desired position. If so, the corresponding recorded material is played from the currently highlighted preview window to an end of the recorded material.
INDUSTRIAL APPLICABILITYBy adopting the present invention, a user is able to recognize the overall contents of recorded material selected by the user. In particular, the user is able to recognize the overall contents of a specific recording item, prior to playing back the recorded material and without playing to view the selected recorded material entirely, without using a bookmark function of a progress bar. With corresponding time information displayed above each thumbnail, a running time can be predicted with respect to a specific recording position. The present invention is nevertheless applicable to a display device provided with a general time-shift function.
Thus, the present invention provides a method of displaying recorded material and a display apparatus using the same, which facilitates user recognition of the contents of selected recorded material prior to its reproduction, as well as user recognition of the contents of all recorded material available for reproduction, so that the recognition and designation for playback of a specific recording position of recorded material selected by a user.
Furthermore, as described above, the storage medium employed by the display device according to the present invention may be externally or even remotely disposed, and the extraction and storage of the plurality of sample images for simultaneous display respectively via a corresponding plurality of preview windows according to the present invention may be performed in response to an arbitrary user selection from a displayed recording item list, that is, after completion of a corresponding recording operation. As such, the corresponding recording operation may have been performed, at some earlier time, by a party or operator unknown to the primary (or instant) user. Therefore, the present invention is applicable in cases where the user has not performed any recording operation, or where the user is otherwise unaware of the extent or currently availability of the recorded material, and in cases where new or existing content may be updated or changed regularly as through an Internet-based storage device or video service, that is, a storage medium maintained by others to include video content wholly unknown to the user.
The present invention is also applicable to photo series and to separate video-recorded material including digital interne video express (DIVX) and universal serial bus (USB) video recorded materials. In the case of a photo series, each photo (i.e., recording item) includes a title and a size. A USB or DIVX recording item can include the same information as a moving picture recording item.
While the present invention has been described and illustrated herein with reference to one or more preferred embodiments, it will be apparent to those skilled in the art that various modifications can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention covers such modifications provided they come within the scope of the appended claims and their equivalents.
