Here, the digital broadcasting receiver means a broadcasting receiver capable of receiving digital broadcasting transmitted as digital video and audio signals. Digital broadcasting refers to a broadcasting technology capable of bi-directional operation, reproduction and accumulation because it compresses and outputs a television signal in a digital form in which information signals are encoded and recorded unlike conventional analog broadcasting. Compared to analog broadcasting, such digital broadcasting is strong against noise and has a small data loss, and since it transmits separate error correction information, it is advantageous for error correction and provides a high resolution and clear screen. Also, unlike analog broadcasting, digital broadcasting can receive a broadcasting service from a broadcasting station and provide bidirectional service to provide information to a broadcasting station. In the present invention, digital broadcasting is used not only for broadcasting through terrestrial, satellite, and cable but also for broadcasting transmitted through an Internet network. That is, digital broadcasting defines the concept including IP (Internet Protocol) broadcasting. Also, in the present invention, a digital broadcast receiver includes a broadcast receiver capable of providing an Internet service to a viewer. Here, the Internet service includes communication services such as information services such as CoD (content's on demand) service, YouTube service, weather, news, local information and search, entertainment services such as games and karaoke, TV mail and TV SMS And the like can be provided through the Internet. Accordingly, the digital broadcast receiver in the present invention includes a network TV, a web TV, and a broadband TV. The broadcasting service may include an Internet service as well as a broadcasting service provided through terrestrial, satellite, and cable.

Meanwhile, the content provider 20 can provide a service to the user 40 using a unicast or multicast method. The unicast method is a method of transmitting data 1: 1 between one sender and one receiver. For example, in a unicast method, when a receiver requests data from a server, the server can transmit data to the receiver upon request. The multicast method is a method of transmitting data to a plurality of receivers of a specific group. For example, the server can transmit data to a plurality of pre-registered receivers at once. An Internet Group Management Protocol (IGMP) protocol may be used for multicast registration.

The network provider 30 may provide a network for providing services to the user 40. The user 40 may construct a home network end user (HNED) to receive a service.

As a means for protecting the content transmitted from the content providing system, a conditional access or a content protection may be used. As an example of such restriction reception or content protection, a scheme such as a cable card (CableCARD) and a DCAS (Downloadable Conditional Access System) may be used.

On the other hand, the user 40 can also provide the content through the network. In this case, conversely, conversely, conversely, the user 40 may be a content provider and the content provider 10 may receive content from the user 40. [ Thereby enabling bidirectional content services or data services.

Also, for example, if the demultiplexed video signal is an encoded video signal of the H.264 standard according to the DMB (Digital Multimedia Broadcasting) scheme or DVB-H, it can be decoded by the H.264 decoder.

Meanwhile, the video signal decoded by the video processor 320 is input to the mixer 350.

The OSD generation unit 340 generates an OSD signal according to a user input or by itself. For example, based on a user input signal or a control signal, a signal for displaying various information in graphic or text on the screen of the display unit 180 can be generated. The generated OSD signal may include various data such as a user interface screen of the display device 100, various menu screens, widgets, icons, and the like.

For example, the OSD generating unit 340 may generate a signal for displaying broadcast information based on a caption of a broadcast image or an EPG.

The mixer 350 may mix the OSD signal generated by the OSD generator 340 and the decoded video signal processed by the image processor 220. The mixed signal is provided to formatter 360. Since the decoded broadcast video signal or the external input signal and the OSD signal are mixed, the OSD can be overlaid on the broadcast image or the external input image.

A frame rate converter (FRC) 355 can convert a frame rate of an input image. For example, a frame rate of 60 Hz is converted to 120 Hz or 240 Hz. When converting the frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame between the first frame and the second frame, or insert the third frame predicted from the first frame and the second frame. When converting a frame rate of 60 Hz to 240 Hz, it is possible to insert three more identical frames or insert three predicted frames. On the other hand, it is also possible to maintain the input frame rate without performing another conversion.

The formatter 360 receives the output signal of the frame rate conversion unit 355 and changes the format of the signal to be suitable for the display unit 180 and outputs the signal. For example, the R, G, and B data signals may be output as low voltage differential signaling (LVDS) signals or mini-LVDS signals.

On the other hand, the audio processing unit (not shown) in the control unit 170 can perform the audio processing of the demultiplexed audio signal. To this end, the voice processing unit (not shown) may include various decoders.

When a demultiplexed speech signal is a coded speech signal, the speech processing unit (not shown) in the control unit 170 can decode the demultiplexed speech signal. For example, the demultiplexed speech signal may be decoded by an MPEG-2 decoder, an MPEG 4 decoder, an AAC decoder, or an AC-3 decoder.

In addition, the audio processing unit (not shown) in the control unit 170 can process a base, a treble, a volume control, and the like.

The data processing unit (not shown) in the control unit 170 can perform data processing of the demultiplexed data signal. For example, if the demultiplexed data signal is a coded data signal, it can be decoded. The encoded data signal may be EPG (Electronic Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel. For example, the EPG information may be ATSC-PSIP (ATSC-Program and System Information Protocol) information in the case of the ATSC scheme and may include DVB-SI information in the DVB scheme . The ATSC-PSIP information or DVB-SI information may be information included in the above-described stream, i.e., the header (4 bytes) of the MPEG-2 TS.

Conversely, when the user moves the remote control apparatus 200 close to the display unit 180, the selection area within the display unit 180 corresponding to the pointer 205 may be zoomed out and displayed. On the other hand, when the remote control device 200 moves away from the display unit 180, the selected area is zoomed out, and when the remote control device 200 approaches the display unit 180, the selected area may be zoomed in.

On the other hand, when the specific button in the remote control device 200 is pressed, it is possible to exclude recognizing the up, down, left, and right movement. That is, when the remote control device 200 moves away from or approaches the display unit 180, it is not recognized that the up, down, left, and right movements are recognized, and only the forward and backward movements are recognized. Only the pointer 205 is moved in accordance with the upward, downward, leftward, and rightward movement of the remote control device 200 in a state where the specific button in the remote control device 200 is not pressed.

On the other hand, the moving speed and moving direction of the pointer 205 may correspond to the moving speed and moving direction of the remote control device 200.

The pointer in the present specification means an object displayed on the display unit 180 in correspondence with the operation of the remote control device 200. [ Therefore, various shapes of objects other than the arrow shapes shown in the figure are possible with the pointer 205. [ For example, it can be a concept that includes points, cursors, prompts, thick outlines, and so on. The pointer 205 may be displayed corresponding to a point on a horizontal axis or a vertical axis on the display unit 180 or may be displayed corresponding to a plurality of points such as a line or a surface Do.
