According to an aspect of an exemplary embodi AND CONTROL METHOD THEREOF ment, there is provided a broadcasting receiving apparatus including a receiver which includes a plurality of tuners, a CROSS-REFERENCE TO RELATED storage part which is capable of storing therein an image APPLICATION received by the receiver and a controller configured to control at least one of the plurality of tuners that does not tune to a 0001. This application claims priority from Korean Patent currently viewed image out of the plurality of tuners, to alter Application No. 10-2013-0052429, filed on May 9, 2013 in nately tune to a plurality of channels for a preset time, and to the Korean Intellectual Property Office, the disclosure of control the storage to store a channel information image cor which is incorporated herein by reference in its entirety. responding to respective channels based on a images tuned to BACKGROUND by the at least one tuner. 0012. The channel information image may include a video 0002 1.

The broadcasting receiving apparatus may further 0004 2. Description of the Related Art include an electronic program guide (EPG) generator which 0005. A broadcasting receiving apparatus may receive, generates an EPG which provides broadcasting information and output, broadcasting signals through various routes Such of channels and including a plurality of mosaics correspond as terrestrial, cable, satellite and Internet protocol (IP) and ing to a plurality of channels, wherein the EPG generator may be implemented as a set-top box or a digital television generates the EPG including channel information images of (DTV). In recent years, the broadcasting receiving apparatus channels corresponding to the plurality of mosaics. has provided a user with programs of various channels, and 0015 The EPG generator may arrange mosaics of the EPG attempts have been made for a user to efficiently and intu based on at least one of among viewing history, user infor itively select and view Such various programs. mation and genre. 0006. As a part of such attempts, electronic program guide (0016. The EPG generator may generate the EPG by over (EPG) service has been commercialized to provide a user laying the channel information image with a text or graphic with information of various broadcasting programs, and may including information of channels corresponding to the enhance a user's convenience, compared to the conventional mosaics. method of changing a viewed channel via channel up/down 0017. The controller may sequentially tune to channels in since the EPG provides information of various available the order of channels corresponding to mosaics which are channels. adjacent to the focused mosaic in the EPG. 0007. The EPG may be provided in more various manners 0018. The receiver may include a plurality of processors since the broadcasting transmission has been transitioned configured to descramble images provided by the plurality of from analog to digital broadcasting. Digital broadcasting tuners based on a right to access, and the storage stores a compresses program data per channel with high efficiency plurality of images descrambled by the plurality of proces based on Moving Picture Experts Group (MPEG) specifica SOS. tions, multiplexes and transmits broadcasting signals based 0019. If a request for changing a channel is received, the on digital modulation, and thus has more strength in efficient controller may decode and output the channel information use of frequency and availability of broadcasting channels images stored in the storage. than existing analog broadcasting. 0020. The broadcasting receiving apparatus may further 0008. Notwithstanding such strengths, the digital broad include a display configured to display the images and the casting has some weaknesses, and a representative example EPG thereon. of the weaknesses is an increase in time for changing a chan 0021. According to an aspect of another exemplary nel. In analog broadcasting, it takes a relatively short time to embodiment, there is provided a control method of a broad change a channel, whereas in digital broadcasting, it may take casting receiving apparatus including alternately tuning to a 2 or 3 seconds to tune to the channel to be changed, and to plurality of channels for a preset time through at least one of descramble the channel. tuners which does not tune to a currently viewed image out of 0009. In one exemplary embodiment, a method for guar a plurality of tuners and storing a channel information image anteeing continuity of viewing by providing a user with corresponding to respective channels based on the image proper contents during a channel-changing time, and forming tuned by at least one tuner. an EPG required to do so. 0022. The control method may further include receiving a request for changing a channel, outputting channel informa SUMMARY tion images corresponding to the requested channel and out 0010. Accordingly, one or more exemplary embodiments putting an image of the tuned channel if the tuning of the provide a broadcasting receiving apparatus and a control requested channel is completed. method thereof which provides electronic program guide 0023 The control method may further include generating (EPG) for a user to efficiently search channels as well as an EPG providing broadcasting information of respective providing a user with proper content during a channel-chang channels and including a plurality of mosaics corresponding ing time.
