1SEG TELEVISION FOR DISPLAYING A STREAM INFORMATION < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-seg television, which is a Japanese mobile television, and more specifically, to a one-seg television capable of displaying language information supported by a received stream.

'One Seg' is an abbreviation of one segment. It is a name derived from dividing a channel for digital broadcasting into 13 segments and using one of the segments. One segment-compatible devices are appearing in various mobile devices such as mobile phones. Currently, the one-segment compatible device is referred to as one-seg television.

As described above, the one-seg television described above is a mobile television set for Japan, and is a one-segment (1seg) service for a terrestrial digital broadcasting mobile device capable of enjoying a terrestrial broadcast television program on a mobile phone or a miniature television, Means a device that supports broadcasting. One Seg broadcasting is a service that provides video, audio, and data, but uses a part of the channel of digital TV broadcasting in Japan, not independent broadcasting. Although the transmission is not large, it is sufficient for small devices such as mobile devices, and video broadcasting (video) supporting the H.264 / AVC standard and audio broadcasting (voice) supporting the MPEG-2 AAC standard are being implemented . Further, it is possible to link and display detailed broadcast content (BML, Broadcast Markup Language) from the broadcasting station through the Internet by linking the data broadcast (data). Furthermore, since it is possible to link to other networks via the Internet, there is an advantage that the cooperation service of broadcasting / communication is easy.

The one-seg television supporting the one-seg broadcasting receives the various types of streams from the broadcasting station by its nature. However, the information of the transmitted stream and the method of the kind of the language supported by the stream transmitted specifically are not presented have.

Therefore, the user has to confirm the language supported by the received stream, which inconveniences the user, which causes the reliability of the entire one-seg television to be used to be reduced.

SUMMARY OF THE INVENTION The present invention has been made to overcome the above problems, and it is an object of the present invention to allow a user to easily grasp a kind of language supported by a stream received from a One Seg television.

According to an aspect of the present invention, there is provided a one-seg television according to an embodiment of the present invention, comprising: an extracting unit for analyzing a stream of one-Seg broadcast data and extracting a type of a supported language supported by the stream; And a display unit for displaying the type of the extracted supported language.

In one embodiment of the present invention, the apparatus may further include a playback unit for playing back the support language determined by the user's selection.

In one embodiment of the present invention, the extracting unit may analyze a flag related to a supported language in a program map table (PMT) in the stream.
In one embodiment of the present invention, the flag associated with the supported language includes information indicating that the stream includes at least one of a single language, a multi-language, a BML (broadcast markup language), and a closed caption language can do.
In an embodiment of the present invention, the display unit may display a user-selectable type of supportable language in a predetermined portion of the screen.
In an embodiment of the present invention, the display unit may display the type of the supported language selected by the user differently from the type of the other supported language.

As described above, the one-seg television capable of displaying the stream information according to the present invention displays the stream information, specifically the type of the language supported by the stream, so that the user can easily grasp the type of the language So as to improve the reliability of the product.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically showing a one-seg television capable of displaying stream information according to a preferred embodiment of the present invention.

Referring to FIG. 1, a one-seg television capable of displaying stream information according to the present embodiment includes a supported language extracting unit 10 for analyzing a received stream and extracting a type of a language supported by the stream, And a support language display unit 20 for displaying the type of the language.

The support extracting unit 10 receives and analyzes a stream transmitted from a predetermined broadcast medium, and extracts a type of a language supported by the stream. Since the extraction of the type of the supported language is within the analysis range of the stream, when it is necessary to analyze the stream information for another purpose, it can be performed in parallel with the stream information analysis for the other purpose.

The type extraction of the supported language is based on the premise that the received stream includes information indicating the type of language supported by the stream. One Seg broadcasting also includes the kinds of languages supported in the stream. Specifically, the types are stored in 'StreamType' in Program Map Table (PMT). The PMT includes information (PID, Program Identification, and program identification information) about a video / audio stream in a program (stream), and is parsed to obtain actual video / audio information at the time of watching television. It is possible to extract the type of the language supported by the stream by extracting 'StreamType'. Of course, the above example conforms to the stream standard supported by the current one-seg broadcasting, and it is recalled that the present invention is not limited to the above example in consideration of a case where a later specification or the like is changed.

FIG. 2 shows the structure of a PMT in a stream used in a one-segment broadcasting. The 'StreamType' is located on the 'N loop' of the 2 ^nd loop of the received stream, and one of the StreamType shown in Table 1 is stored. The 'ES info length' located on the right side of 'StreamType' in FIG. 2 defines the length of the 'N loop'. As a result, the necessary number of 'StreamType' is arranged in the 'N loop'. One of 0x1B indicating video information, 0x0F indicating audio information 1 and 2, 0x0D indicating BML information, and 0x06 indicating closed caption is recorded in the 'StreamType'. In case of storing a plurality of pieces of information, Another StreamType existing on the 'N loop' is used.

At present, the maximum number of 'StreamType' allowed in the one-seg broadcasting stream is five, and the video, audio 1, 2, BML, and closed caption information listed above can be respectively allocated. Since the StreamType of Audio 1 and Audio 2 is equal to 0x0F, it is possible to judge whether a single audio (there is only one 0x0F) or multiple audio (two 0x0F exists) as the number of times that 0x0F appears. As a result, since audio 1 and audio 2 are included in the audio (audio), it is possible to judge whether a single language or multiple languages are supported by assigning audio 1 and audio 2 in 'StreamType'. In addition, when '0x0D' is assigned to 'StreamType', it means that it supports Broadcast Markup Language (BML), and when 0x06 is assigned, it supports closed caption language. This means that the language supported by the stream is one of multi-language, BML, and closed caption, but it is not limited to this, and various types of languages are also expected to be supported.

As a result, the supported language extracting unit 10 extracts the language supported by the received stream by analyzing the StreamType included in the 'StreamType'.

The supported language display unit 20 displays the type of the supported language extracted by the supported language extracting unit 10 so that the recognized language can be recognized by the user. The support display unit 20 can display images or audio (including sound), but it is more preferable to display images and images in order to display various kinds of supported languages.

Preferably, the image display of the supported language type is performed at the upper or lower part of the screen, and particularly displayed at the upper part of the screen. One-Seg television is mostly applied to mobile devices, so that displaying on the top of the screen displaying the status of the system, such as the reception state and the battery state, in the mobile device can be displayed without invading another screen. It is also intended to meet the expectation that the user will be presented with a type of supported language in the system status window.

For example, in case of multiple languages, '2L' (indicating that two languages are supported), and in the case of BML, 'B' for closed caption language, and 'C' for closed caption language. It goes without saying that such an example can be variously changed in consideration of the convenience of the user.

If there is only one language supported by the support language extracting unit 10, that is, when the user selects only one language when a certain channel is selected, the language (pronunciation) It is not necessary to carry out a specific display, but it is also possible to display an abbreviation for a single language or display it only when the user desires through the setting of an option.

FIG. 3 shows the output of the kind of the supported language on the actual screen of the one-seg television.

When the user selects television conversion by using a screen of the one-seg television (touch screen method) or a shortcut key for viewing the television, the one-seg television obtains the A / V parsing information, Information on a stream, specifically, information on a language supported by the stream, and displays the result on the screen through the support language display unit 20. [ As described above, in FIG. 3, the supported languages are displayed as '2L', 'B', and 'C' in the upper system status display field of the screen.

By displaying the type of the language supported by the received stream, the user can recognize the type of the language supported by the program being watched without difficulty, and convenience for using the content is increased.

Meanwhile, it is desirable that the desired service can be provided immediately by selecting the displayed supported language without being limited to the display of the supported language. For this purpose, as shown in FIG. 4, It is preferable to further include a playback unit 30 as far as possible.

When the user selects one of the supported language information displayed through the support language display unit 20, the playback unit 30 processes the supported language corresponding to the selected support language and outputs it in the form of voice or text of the content , And selects '2L', i.e., multiple languages as shown in FIG. 5, to select one of the two available languages to be displayed again in the submenu. Currently, only two languages (Japanese and English) are shown in this embodiment because it is limited to two kinds of multiple languages supported by one-seg broadcasting. However, it is recalled that this can be changed according to future specification changes and technological developments. When the user selects 'English', the playback unit 30 extracts information corresponding to the user's selection from the stream and outputs the language of the English pronunciation. If 'Japanese' is selected, The language of the Japanese pronunciation is outputted by the operation.

When the user selects 'B', the playback unit 30 extracts corresponding information from the stream and outputs BML as shown in FIG. 6 (right).

If the user selects 'C', the reproducing unit 30 extracts corresponding information from the stream and outputs the subtitles as shown in FIG. 7 (right).

For convenience of the user, the playback unit 30 may display the currently output language in cooperation with the supported language display unit 20. For example, when the BML is being output, the 'B' corresponding to the BML can be made brighter than the other supported language indications '2L' and 'C' during the display of the supported language through the supported language display unit 20, The color may be different. In the case of '2L' representing multiple languages, '2L' may be processed as the above 'B', but since it is easier to recognize the type of the currently displayed language, It may be desirable to change. That is, when 'English' is selected and the language of English pronunciation is being outputted, 'E' and 'Japanese' are selected instead of '2L', and when the language of Japanese pronunciation is being outputted, 'J' Is preferred.

Also, before the user selects any one of the supported languages, it is preferable that any one of the languages should be output, and it is preferable that the language can be changed through option setting or the like.

Meanwhile, the playback unit 30 should be associated with a means such as a touch screen or a shortcut key for receiving a user's selection in order to output a user's selection. The input means will not be discussed in detail.

Referring to FIG. 8, the operation of the one-seg television capable of displaying the stream information according to the embodiment shown in FIG. 4 will be described. When the user of the one-seg television switches to the television viewing (S110) And receives the stream (S 120). The supported language extracting unit 10 analyzes the received stream, extracts the type of the language supported by the stream (S 130), and the extracted result is displayed as video or audio through the supported language display unit 20 (S 140). When the supported language is displayed by voice, the type of the language supported by the currently received stream is informed by the user's local language. When displaying the supported language by video, the type of the supported language is displayed at a predetermined position on the screen do. The display position is preferably the upper end of the screen as the system status window, as described above. By displaying the kind of the supported language in this manner, the user can grasp the type of the language supported by the received stream, thereby facilitating the user's convenience. If the user selects a desired language among the displayed languages, the user is prompted to select the desired language (S 150), the language supported by the language (S 160) is reproduced and output (S 170) Allow the user to be provided with the desired support language.

In the above process, the broadcasting program corresponding to the received stream is to be reproduced in a certain language even before the user selects the supported language. It is preferable that the broadcasting program is basically outputted in the language of his / her own (voice) It is desirable to make the change possible.
