BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

As used herein, terms used in the present invention are selected from general terms that are widely used in the present invention while taking into account the functions of the present invention, but these may vary depending on the intention or custom of a person skilled in the art or the emergence of new technologies. In addition, in certain cases, there is a term arbitrarily selected by the applicant, and in this case, the meaning will be described in the corresponding description of the invention. Therefore, it is intended that the terminology used herein should be interpreted based on the meaning of the term rather than on the name of the term, and on the entire contents of the specification.

In addition, the USB storage device described below is a concept including not only a USB memory and an external USB hard disk but also an external device having a storage space inside the device and connectable to the image display device through a USB connection port.

 1 is a view schematically showing an example of an entire broadcasting system including a video display device according to an embodiment of the present invention.

As shown in FIG. 1, an entire broadcasting system including a video display device according to an embodiment of the present invention includes a content provider (CP) 10, a service provider (SP) 20, It may be divided into a network provider (NP) 30 and an HNED 40. The HNED 40 corresponds to, for example, the client 100 which is a video display device according to an embodiment of the present invention. The client 100 corresponds to an image display device according to an embodiment of the present invention, and the image display device is, for example, a network TV, a smart TV, an IPTV, or the like.

The content provider 10 produces and provides various contents. As shown in FIG. 1, the content provider 10 includes a terrestrial broadcaster, a cable system operator or a multiple system operator, a satellite broadcaster, and an internet broadcaster. An internet broadcaster and the like can be exemplified.

In addition to the broadcast content, the content provider 10 may provide various applications. In this regard, it will be described later in more detail.

The service provider 20 may provide a service package of contents provided by the content provider 10. For example, the service provider 20 of FIG. 1 may package and provide a first terrestrial broadcast, a second terrestrial broadcast, a cable MSO, satellite broadcast, various internet broadcasts, applications, and the like to a user.

Meanwhile, the service provider 20 may provide a service to the client 100 using a unicast or multicast scheme. The unicast method is a method of transmitting data 1: 1 between one sender and one receiver. For example, in the unicast method, when a receiver requests data from a server, the server may transmit data to the receiver according to the request. Multicasting is a method of transmitting data to a plurality of recipients of a specific group. For example, the server can send data to multiple pre-registered receivers at once. For such multicast registration, the Internet Group Management Protocol (IGMP) protocol may be used.

The network provider 30 may provide a network for providing a service to the client 100. The client 100 may establish a home network end user (HNED) to receive a service.

As a means for protecting the content transmitted from the video display device system, a conditional access or a content protection may be used. As one example for such a restriction reception or content protection, a scheme such as a cable card or a downloadable conditional access system (DCAS) may be used.

On the other hand, the client 100 can also provide content through the network. In this case, unlike the above, the client 100 may be a content provider, and the content provider 10 may receive content from the client 100. In the case of designing as described above, an interactive content service or a data service is possible.

On the contrary, the tuner 110 and the network interface unit 130 may be provided. The demodulator 120 may be designed so as not to be included.

The tuner 110 selects an RF broadcast signal corresponding to a channel selected by a user or all pre-stored channels among RF (Radio Frequency) broadcast signals received through an antenna. Also, the selected RF broadcast signal is converted into an intermediate frequency signal, a baseband image, or a voice signal.

For example, if the selected RF broadcast signal is a digital broadcast signal, it is converted into a digital IF signal (DIF). If the selected RF broadcast signal is an analog broadcast signal, it is converted into an analog baseband image or voice signal (CVBS / SIF). That is, the tuner 110 may process both digital broadcast signals or analog broadcast signals. The analog baseband video or audio signal CVBS / SIF output from the tuner 110 may be directly input to the controller 170.

In addition, the tuner 110 may receive an RF broadcast signal of a single carrier according to an Advanced Television System Committee (ATSC) scheme or an RF broadcast signal of a plurality of carriers according to a digital video broadcasting (DVB) scheme.

Also, the demodulation unit 120 may perform channel decoding. To this end, the demodulator 120 includes a trellis decoder, a de-interleaver, and a reed solomon decoder to perform trellis decoding, deinterleaving, Solomon decoding can be performed.

For example, when the digital IF signal output from the tuner 110 is a DVB scheme, the demodulator 120 performs coded orthogonal frequency division modulation (COFDMA) demodulation, for example. Also, the demodulation unit 120 may perform channel decoding. For this, the demodulator 120 may include a convolution decoder, a deinterleaver, and a reed-solomon decoder to perform convolutional decoding, deinterleaving, and reed solomon decoding.

The demodulator 120 may output a stream signal TS after performing demodulation and channel decoding. In this case, the stream signal may be a signal multiplexed with a video signal, an audio signal, or a data signal. For example, the stream signal may be an MPEG-2 TS (Transport Stream) multiplexed with an MPEG-2 standard video signal, a Dolby AC-3 standard audio signal, or the like. Specifically, the MPEG-2 TS may include a header of 4 bytes and a payload of 184 bytes.
