Referring to
The multimedia signal may include multimedia data. For example, the multimedia may refer to various mediums including audio, text, images, video, and the like. Therefore, the multimedia data may include one or more of audio data, text data, image data, video data, and the like. The multimedia signal may refer to the multimedia data or a signal converted from the multimedia data to use various wired or wireless transmission paths.
The multimedia signal included in the first signal may include content that may not be changed by a user. For example, the multimedia signal may include a broadcasting signal transmitted from a broadcasting station, various multimedia data registered in a web server by a third-person user, multimedia data stored in a compact disc/digital versatile disc (CD/DVD), and the like. In some examples, the first signal may include a control signal for the multimedia signal.
The first signal may have a format of national television system committee (NTSC), Phase Alternating Line (PAL), a cable broadcasting signal, a satellite broadcasting signal, a terrestrial broadcasting signal, a digital multimedia broadcasting (DMB) signal, a video codec, an audio codec, and the like.
According to various aspects, it is possible to update content by the user with a second signal that includes user data. For example, the user data may include audio data, text data, image data, video data, multimedia data, and the like.
The first signal unit 110 may obtain the first signal that includes the multimedia signal. There are various methods by which the first signal unit 110 may obtain the first signal. For example, the first signal may be received from a broadcasting signal transmitted from a broadcasting station. The first signal may be extracted from a storage unit internally provided or from an external database (DB). As another example, the first signal may be generated using an input unit such as an internal or external multimedia authoring tool.
The second signal unit 130 may obtain the second signal input by the user and which includes the user data. Unlike the content of the first signal, the content of the second signal may be generated, changed, and/or updated by the user. For example, the second signal may include a short message service (SMS) message, a multimedia message service (MMS) message, advertisement data, guide data, and the like, each of which may include multimedia data such as images and audio data.
As an example, an SMS message and a MMS message may be a message to deliver to a family member. The advertisement data may be advertisement data generated by a small enterprise such as a restaurant. The guide data may be information data of a hospital.
The signal output unit 150 may receive the first signal from the first signal unit 110, receive the second signal from the second signal unit 130, and simultaneously output the first signal and the second signal together such that image data from the first signal is simultaneously displayed together with image data of the second signal.
Therefore, a receiving end of the signal output unit 150 may receive both the first signal and the second signal. If the receiving end is a multimedia apparatus that has a multimedia data reproduction function, such as a TV, an environment may be provided to display the first signal and the second signal together.
The first signal may be output from the signal output unit 150 through a pre-installed wired or wireless transmission line for a multimedia signal to various multimedia apparatuses such as a display reproduction apparatus. In this example, the signal output unit 150 may additionally output the second signal through the pre-installed transmission line. That is, the same wired or wireless transmission line may be used for both the second signal and the first signal. For example, if the first signal uses a channel of a predetermined frequency band, the second signal may also use the same channel.
An output signal of the signal output unit 150 may include two signals, that is, the first signal and the second signal. A conventional multimedia reproducing apparatus that typically only receives the multimedia signal included in the first signal may is not able to receive and process the second signal. According to various aspects, the multimedia apparatus described herein may include a signal processing unit 140 as shown in
Referring to
In this example, the signal processing unit 140 may generate a third signal by embedding a second signal obtained by the second signal unit 130 in a first signal obtained by the first signal unit 110. In addition, the signal output unit 150 may output the third signal instead of the first signal and the second signal.
The third signal, which refers to a combined signal of the first signal and the second signal, may use a signal type of the first signal to maintain use of the pre-installed transmission line for transmission of the multimedia signal. In this example, the signal processing unit 140 may convert a signal type of the third signal that is a combination of the first signal and the second signal into a signal type of the first signal. As another example, the second signal may be embedded in the first signal so that the third signal automatically has the signal type of the first signal.
The signal processing unit 140 and the signal output unit 150 described herein may output only the third signal having the same signal type as the first signal. As a result, a multimedia reproducing device that receives an output signal of the signal output unit 150 may reproduce and display the received third signal without an additional device. Such an effect is remarkable when the signal output unit 150 is included in a broadcasting server.
Referring to example of
Irrespective of whether the first signal unit 110, the second signal unit 130, and the signal processing unit 140 are included in the broadcasting server, the third signal output from the signal processing unit 140 may be transferred to the signal output unit 150 included in the broadcasting server. Accordingly, the broadcasting server may include a broadcasting unit (not shown) to convert the third signal into a broadcasting signal and output the broadcasting signal. In this example, the broadcasting unit may be included in the signal output unit 150.
The broadcasting unit may generate the broadcasting signal by converting the third signal. Because a source input to the broadcasting unit is just the third signal, only conversion of the third signal is necessary in the same manner as when one piece of conventional multimedia data is converted into the broadcasting signal. Accordingly, a broadcasting unit may maintain its existing structure.
In various examples, the broadcasting server may transmit the converted broadcasting signal to a pre-installed antenna or in a conventional method through a pre-installed cable. Accordingly, the broadcasting server does not need a separate transmission line for the second signal and a separate broadcasting unit to convert the second signal into the broadcasting signal. In addition, the user may still use an existing display unit.
Referring to
For example, the first signal unit 110 may obtain a first signal from multimedia providing servers such as a broadcasting server, a network server, and the like. As another example, the first signal may be obtained from various multimedia players such as a CD/DVD display, Blu-ray player, and the like. In addition, the first signal unit 110 may transmit the first signal to the signal output unit 150.
The output terminal of the signal output unit 150 may be connected to the input terminal of the display unit through the set-top box. For example, the set-top box may be equipped with an interface (not shown) connected to the output terminal of the signal output unit 150 with one end and to the input terminal of the display unit with the other end.
The output terminal of the signal output unit 150 and the input terminal of the display unit may be interconnected, for example, by a wire or by a wireless communication line. In this example, the output terminal of the signal output unit 150 and the input terminal of the display unit are interconnected one to one.
Because the signal output unit 150 and the display unit are interconnected, a target of the signal output from the signal output unit is clear. Therefore, the second signal output from the corresponding set-top box may be estimated as requested by the user of the display unit. In this example, a unit to select a target display unit of the second signal, for example, an address receiving unit 160 of
Referring to
The second signal unit 130 includes an input unit 133 that generates the second signal by receiving input from a user. The input unit 133 may include a user input tool such as a keyboard, a multimedia authoring tool generating the second signal through operation of the user input tool, a check unit displaying the second signal to the user, a mouse, a touchpad, and the like. Thus, the second signal unit may obtain the second signal by generating the second signal through the input unit.
In addition, the second signal unit 130 may include a storage unit 135 to store the second signal and an extraction unit 137 to extract the second signal stored in the storage unit 135. The storage unit 135 may store at least one second signal. The second signal stored in the storage unit 135 may be transmitted from the receiving unit 131 or the input unit 133. The storage unit 135 may be separately structured from the second signal unit 130 and installed in the second signal unit 130 after the user stores the second signal. Various storage units such as a CD/DVD and Blu-ray discs are examples of the storage unit 135. The extraction unit 137 may extract at least a part of the second signal stored in the storage unit 135. The signal extracted by the extraction unit 137 may be a portion of or the entire second signal stored in the storage unit 135.
In addition, the multimedia apparatus may include an address receiving unit 160 to receive a network address of the display unit. In a system, for example, a broadcasting system that receives and displays the signal output from the signal output unit 150 by a plurality of display units, the second signal may be displayed together with the first signal even on a display unit that is not capable of displaying a signal of the second signal. The address receiving unit 160 may be used to prevent such a case. For example, the address receiving unit 160 may provide a received network address of the display unit to the signal output unit 150, so that the signal output unit 150 outputs the first signal and the second signal only on a display unit corresponding to the network address.
In this example, the address receiving unit 160 may receive a network address that demands the second signal. For example, a user may select to receive the second signal though a selection unit provided to the display unit, and the display unit may transmit the network address of the corresponding display unit to the address receiving unit 160. Also, the address receiving unit 160 may receive the network address of the display unit from a DB with which the network address demanding the second signal is registered.
The signal output from the signal output unit 150 may be used in various manners. For example, the signal output from the signal output unit 150 may be displayed on the display unit. Accordingly, the multimedia apparatus may include a display area set unit 170 to set a display area for the second signal on a display screen of the display unit.
The display unit that receives the first signal and the second signal output from the signal output unit 150 may display either or both of the first signal and the second signal. If the second signal is displayed together with or independently from the first signal, the display area set unit 170 may set an area to display the second signal on the display screen of the display unit. The output signal of the signal output unit 150 may include setting information of the display area for the second signal. According to various examples, the display unit may receive the setting information and display the second signal on the display area included in the setting information by analyzing the setting information.
For example, the setting information output from the signal output unit 150 may include at least one of preset setting information, setting information input from an outside device, setting information received from the outside device, and the like. The preset setting information may be stored in a storage unit in advance. The setting information input from the outside may be input through an input unit. The setting information received from the outside may be received by a receiving unit. In various examples, the storage unit, the input unit, and the receiving unit may be integrally formed with the storage unit 135, the input unit 133, and the receiving unit 131 of the second signal unit, respectively.
As an example, the first signal and the second signal may be displayed together on a screen. In this example, the second signal may be displayed as an overlay state on the display screen for the first signal. For example, the multimedia apparatus may include a signal conversion unit 180 to convert the second signal into a signal of the same signal type as the first signal and transfer the converted second signal. As one example, the first signal may include a multimedia signal used in a conventional display unit and the like. Therefore, if the signal type of the second signal becomes the same as the signal type of the first signal including the multimedia signal, the display unit may directly use the second signal without another separate unit.
For example, the first signal may have a format including at least one of NTSC, PAL, a cable broadcasting signal, a satellite broadcasting signal, a terrestrial broadcasting signal, a DMB signal, a video codec, and an audio codec, and the like. In this example, the signal conversion unit 180 may convert the second signal to the format of the first signal.
As another example, the first signal may have a plurality of signal types. In this example, the signal conversion unit 180 may judge the signal types of the first signal output together with the second signal. The signal conversion unit 180 may judge the signal types of the first signal by receiving the first signal obtained by the first signal unit.
A display unit may receive the signal output from the signal output unit 150. The display unit may receive the first signal and display the first signal on a screen such as a panel. In addition, the display unit may selectively receive the second signal output from the signal output unit 150 together with the first signal. Also, the display unit may display the second signal on a display area set on the screen. An example of the display unit is shown in
Referring to
The signal receiving unit 210 may receive the first signal and also the second signal. Because the second signal may be additionally output from a signal output unit, the signal receiving unit 210 may include an antenna or a wired receiving unit capable of receiving the second signal as well as the first signal.
For example, the multimedia display unit 230 may extract the first signal and the second signal separately, and display the second signal on the set display area of the screen while simultaneously displaying the first signal on the screen. The first signal or the second signal may include audio data. Therefore, the multimedia display unit 230 may further include a speaker to output the audio data.
The display area of the screen to display the second signal may be set as default, or set using setting information received by the signal receiving unit 210. For example, the display area may be set by a display area set unit 250 provided to the multimedia display unit 230. The display area set unit 250 may enable a user of the multimedia apparatus of
Referring to
The server 310 adapted to provide the multimedia signal may include a broadcasting server, a relay broadcasting server, a network content server, a private broadcasting server, a set-top box connected to the display unit 350, and the like. For example, the server 310 may be provided with a signal output unit to simultaneously output the multimedia signal and the user data.
The mode request unit 330 may generate a request signal to request the server 310 for a first mode to output the multimedia signal to the display unit 350 and a second mode to output the multimedia signal and the user data together to the display unit 350, and transmit the request signal to the server 310.
The server 310 may receive the request signal and analyze the request signal of the mode request unit 330 to determine whether the request is acceptable. For example, if the request is unacceptable, the server 310 may transmit a reject message to the mode request unit 330. If the request is acceptable, the server 310 may drive the signal output unit according to the mode contained in the request signal.
As an example, the server 310 may not accept the request of the mode request unit 330 in various cases. For example, the request may be unacceptable when the user data obtained is absent.
The mode request unit 330 may transmit at least one of user data received by a receiving unit 331, user data generated by an input unit 333, and user data extracted from a storage unit 335 by an extraction unit 337, to the server 310. The data stored in the storage unit 335 may be transmitted from a receiving unit or generated by an input unit and transmitted.
Information indicating that the user data desired to be output by the request signal of the second mode is the user data transmitted from the mode request unit 330 may be included in request information and may be transmitted to the server 310. In addition, the user data may be transmitted to the server 310. For example, the mode request unit 330 may include a data conversion unit 338 to convert the user data to a signal type of the multimedia signal and transmit the converted user data to the server 310, so as to reduce a load of the server 310.
The server 310 may receive the user data transmitted from the mode request unit 330 by a receiving unit provided to a second signal unit, and store the received user data according to the request or output through the signal output unit together with the multimedia signal.
As an example, the multimedia apparatus illustrated in
Referring to
A trigger signal is received in operation 520. In response, user data is displayed together with the multimedia signal on a display area set in a display screen of the multimedia display unit 230, in operation 530. For example, the user data may have a shorter display time than the multimedia signal. Therefore, a point of time to display the user data out of the display time of the multimedia signal may be a significant matter.
Therefore, a trigger generation unit (not shown) may be used. For example, the trigger generation unit may generate a trigger signal at a time point designated by the user or a time point of receiving the user data, and transmit the trigger signal to the multimedia display unit 230. The multimedia display unit 230 receiving the trigger signal may display the multimedia signal and the user data. If the trigger signal is not received, the multimedia display unit may display only the multimedia signal.
The control method illustrated in
If a trigger signal is received from a trigger generation unit (not shown) in operation 620, the multimedia signal and user data are output together, in operation 630. In this example, the signal output unit 150 may output only the multimedia signal if the trigger signal is not received from the trigger generation unit. As another example, if the trigger signal is received from the trigger generation unit, the user data obtained from the second signal may be output together with the multimedia signal.
The trigger generation unit may generate the trigger signal at a time point designated by the user or a time point of receiving the user data.
According to various aspects, a multimedia apparatus is capable of creating a more convenient and enjoyable user experience by displaying a multimedia signal together with a user data signal through various types of multimedia devices.
