The term " wired / wireless network " as used herein refers to a communication network that supports various communication standards or protocols for interconnection and / or data transmission / reception between digital devices or digital devices and external servers . Such a wired / wireless network may include both a communication network to be supported at present or in future by a standard and a communication protocol therefor, such as a Universal Serial Bus (USB), a Composite Video Banking Sync (CVBS) (Bluetooth), Radio Frequency Identification (RFID), and infrared communication (hereinafter, referred to as " wireless communication "), a communication standard or protocol for wired connection such as an analog (DVI), a digital visual interface (DVI), a high definition multimedia interface (WiBro), Wibro (wireless broadband), Wimax (World Interoperability for Microwave), WLAN (Wireless LAN), WiMAX Access), HSDPA (High Speed Downlink Packet Access), LTE (Long Term Evolution), and Wi-Fi Direct.
Hereinafter, in the case of simply designating a digital device, the term " fixed device " or " mobile device "
On the other hand, the digital device is an intelligent device that supports, for example, a broadcast receiving function, a computer function or a support, and at least one external input. The digital device includes an e-mail, a web browsing web browsing, banking, game, application, and so on. In addition, the digital device may include an interface for supporting at least one input or control means (hereinafter referred to as input means) such as a handwriting input device, a touch screen, and a space remote control. The digital device can use a standardized general-purpose OS (operating system). For example, a digital device can add, delete, amend, update, etc. various applications on a general-purpose OS kernel, A user-friendly environment can be constituted and provided.
Meanwhile, the external input described in this specification includes an external input device, that is, any input means or digital device which is connected to the above-mentioned digital device through wire / wireless communication and can transmit / receive related data through it. Here, the external input may be, for example, a game device such as a High Definition Multimedia Interface (HDMI), a play station or an X-Box, a digital device such as a smart phone, a tablet PC, Devices.
The term " server " as used herein includes a client, that is, any digital device or system that supplies data to the above-described digital device, and may be referred to as a processor do. Such servers include, for example, a portal server for providing web pages or web content, an advertising server for providing advertising data, a content server for providing content, An SNS server for providing a social network service, and a service server or manufacturing server provided by a manufacturer.
In addition, the term " channel " as used herein means a path, a means, or the like for transmitting and receiving data, and may be a broadcasting channel. Here, the broadcast channel is represented by terms such as a physical channel, a virtual channel, and a logical channel according to the activation of digital broadcasting. As described above, a broadcast channel is a channel for accessing a broadcast content provided by a broadcasting station or a receiver, and the broadcast content is also referred to as a live channel based on real-time broadcasting . However, in recent years, the medium for broadcasting has been diversified and non-real time broadcasting has been activated in addition to real-time broadcasting. Thus, a live channel is not limited to real-time broadcasting, It may also be understood as a term that refers to the entire channel.
In this specification, an " arbitrary channel " is further defined in relation to a channel in addition to the above-described broadcast channel. The arbitrary channel may be provided with a service guide such as an EPG (Electronic Program Guide) together with a broadcast channel, or may be provided with a service guide, a GUI (Graphic User Interface), or an OSD screen may be configured / provided.
On the other hand, unlike a broadcast channel having a channel number promised beforehand between a transceiver and a receiver, a random channel is assigned to a channel number that is basically no longer duplicated with a channel number for representing the broadcast channel. For example, when tuning a specific broadcast channel, the receiver receives a broadcast signal that transmits broadcast content and signaling information for the broadcast content through the tuned channel. Here, the receiver parses the channel information from the signaling information, and constructs a channel browser, an EPG, and the like based on the parsed channel information, and provides the channel browser, the EPG, and the like to the user. When the user makes a channel switching request through the input means, the receiver corresponds to the channel switching request.
As described above, since the broadcast channel is a content promised beforehand between the transmitting and receiving end, when a random channel is allocated to a broadcast channel in a redundant manner, there is a possibility of confusion or confusion of users, and therefore, . Meanwhile, even if the arbitrary channel number is not duplicated with the broadcast channel number as described above, there is still a possibility of confusion in the channel surfing process of the user. Therefore, it is required to allocate a random channel number in consideration of this. This is because the arbitrary channel according to the present invention can be implemented so as to correspond to a broadcast channel in the same manner in response to a user's channel change request through the input means as in the conventional broadcast channel. Accordingly, the arbitrary channel number may be a random number such as arbitrary channel-1, arbitrary channel-2, or the like, which is not a numeric type like a broadcast channel, for distinguishing or identifying the arbitrary channel access number and the broadcast channel number of the user Can be defined and displayed. In this case, although the display of the arbitrary channel number may be realized in the form of a character, such as arbitrary channel-1, or in the form of a number such as the number of the broadcasting channel inside the receiver. In addition, the arbitrary channel number may be provided in the form of a number such as a broadcast channel, or may be defined and displayed in various ways that can be distinguished from a broadcast channel such as a video channel-1, a title-1, have.
A digital device executes a web browser for a web service to provide various types of web pages to the user. Here, the web page also includes a web page including video content. In the present invention, a moving image is separately or independently processed from a web page. The separated moving picture can be implemented by allocating the above-mentioned arbitrary channel number, providing it through a service guide or the like, and outputting the channel in response to a channel switching request during a service guide or a broadcasting channel viewing process. In addition to the Web service, it is also possible to separate and process predetermined contents, images, audio, items, and the like independently from the broadcasting contents, games, and applications themselves for services such as broadcasting contents, games, Any channel number may be assigned and implemented as described above.

9 is a diagram showing a method of processing multi-channel data between a TV and a database server.
As shown in Fig. 9, the TV may request the database server for authentication for use of the multi-channel service.
Then, the database server, when receiving the authentication request from the TV, can set the serial number, IP address, ID, password, etc. for the TV and accept the authentication.
Then, when the authentication is accepted from the database server, the TV can transmit the identification information of the channel currently viewed to the database server.
Here, the identification information of the channel may include an EPG-based channel ID and a channel name.
Then, the database server can store channel information, device information, and the like received from the TV to which the authentication is accepted.
Next, when the channel currently being watched is changed, the TV can transmit the identification information of the changed channel to the database server.
When the change channel information is received from the TV, the database server can update the stored channel information.
In addition, the TV determines whether there is a video stream request for a currently viewed channel from another TV, and if there is a video stream request, the TV can transmit a video stream for the currently viewed channel to another TV .
Here, the TV can transmit the transmission start information of the video stream to the database server.
Then, the database server can update the stored information when the transmission start information of the video stream is received from the TV.
Then, the TV can transmit the video viewing end information on the video stream received from the other TV to the database server.
Then, the database server can update the stored information when the video viewing end information is received from the TV.
In this manner, the database server can receive and store data processing information for a multi-channel service from a digital device such as a P2P-connected TV or the like, and update the stored information in real time.
FIG. 10 is a flowchart illustrating a method of processing multi-channel service data according to the present invention.
As shown in FIG. 10, the first TV may request the database server for authentication for use of the multi-channel service.
Then, the database server can perform a predetermined authentication procedure to accept the authentication for the first TV.
Next, a plurality of second, third, and fourth TVs can transmit the current viewing channel information currently being watched to the database server.
The database server may then store and update the current viewing channel information of the plurality of TVs.
Then, the first TV may request the database server for a list of a plurality of TVs viewing a second channel.
The database server may then transmit the list of TVs viewing the requested second channel to the first TV.
Next, the first TV can request a P2P connection to the TVs included in the list based on the received list.
And, a plurality of TVs can accept the P2P connection of the first TV.
Then, the first TV may request the second TV to start transmission of the video stream for the second channel, among the TVs to which the P2P connection is accepted.
Next, the second TV starts transmitting the video stream to the first TV, and informs the database server that the video stream starts to be transmitted.
Then, the database server can update the information based on the transmission start information received from the second TV.
Then, the first TV can display the sub video provided by the received video stream and the main video currently viewed together.
If the transmission of the video stream is interrupted, the first TV may request to start transmission of the video stream for the second channel to any one of the other TVs to which the P2P connection is accepted from the second TV.
Here, when the transmission of the video stream from the second TV is stopped, and the list of all the other TVs to which the P2P connection is accepted is lost, the first TV transmits, to the database server, You can request a list again.
Then, the first TV can receive the list of TVs watching the second channel from the database server, and can update the stored list.
As described above, the present invention can provide a multi-channel service to a digital device having a single tuner by P2P connection to a database and a second digital device to transmit or receive a video stream for a second channel.
Accordingly, viewers can easily receive a dual tuning function through a digital device having a single tuner, so that multi-channel viewing and a second TV can be used.
Meanwhile, the operation method of the digital device disclosed in the present specification can be implemented as a code readable by a processor in a recording medium readable by a processor included in the digital device. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium readable by the processor include ROM (Read Only Memory), RAM (Random Access Memory), CD-ROM, magnetic tape, floppy disk, optical data storage, And may be implemented in the form of a carrier-wave. In addition, the processor-readable recording medium may be distributed over network-connected computer systems so that code readable by the processor in a distributed fashion can be stored and executed.
