The apparatus includes a signal receiver which receives an image signal having image content; a user selection unit which selects movie content from the image content; a storage unit; and a controller which determines whether a received image signal is a film image signal if the movie content is selected through the user selection unit, and stores the image signal in the storage unit if the image signal corresponds to the film image signal. ## Claims ### Claim 1 A broadcasting processing apparatus comprising: a storage unit; a controller which, when a movie content storing function is selected, determines whether an image signal received by the broadcasting processing apparatus is a film image signal, and which stores the image signal in the storage unit if the image signal is determined to be a film image signal; a decoder which decodes the image signal; and an interlaced-to-progressive converter (IPC) which detects field images from the decoded image signal, wherein the controller generates a motion change pattern based on field images detected during a first period of time, and determines that the image signal is a film image signal if the generated motion change pattern corresponds to a preset motion change pattern. ### Claim 2 (depends on 1) The broadcasting processing apparatus according to claim 1, wherein the controller generates a motion change pattern based on field images detected during a second period of time longer than the first period of time, determines that the image signal is an advertisement image signal if the motion change pattern of the second period of time is different from a preset motion change pattern, and removes the stored image signal corresponding to the advertisement image signal. ### Claim 3 (depends on 1) The broadcast processing apparatus according to claim 1, wherein the controller determines a frame rate of the image signal and determines that the image signal is an advertisement image signal if the determined frame rate is different from a preset frame rate. ### Claim 4 (depends on 3) The broadcasting processing apparatus according to claim 3, wherein the controller removes the stored image signal corresponding to the advertisement image signal. ### Claim 5 (depends on 1) The broadcasting processing apparatus according to claim 1, wherein the image signal stored in the storage unit is an encoded image signal. ### Claim 6 A broadcasting processing apparatus, comprising: a storage unit; a controller which, when a movie content storing function is selected, determines whether a frame rate of an image signal received by the broadcasting processing apparatus is identical to a preset frame rate, and which stores the image signal in the storage unit if the frame rate of the image signal is identical to the preset frame rate; a decoder which decodes the image signal; and an interlaced-to-progressive converter (IPC) which detects field images from the decoded image signal, wherein the controller determines the frame rate of the image signal based on a motion change pattern of the detected field images. ### Claim 7 (depends on 6) The broadcasting processing apparatus according to claim 6, wherein the preset frame rate is 24 or 25 frames per second. ### Claim 8 A control method of a broadcasting processing apparatus, the control method comprising: receiving a control signal to store movie content of an image signal received by the broadcasting processing apparatus; detecting field images by decoding the image signal; determining whether the image signal is a film image signal by using the detected field images; and storing the image signal if the image signal is determined to be a film image signal, wherein the determining whether the image signal is a film image signal comprises: generating a motion change pattern based on field images detected during a period of time; and determining whether the generated motion change pattern is a preset motion change pattern. ### Claim 9 (depends on 8) The control method according to claim 8, further comprising: determining whether the image signal is an advertisement image signal; and removing the stored image signal corresponding to the advertisement image signal if the image signal is determined to be an advertisement image signal. ### Claim 10 (depends on 9) The control method according to claim 9, wherein the determining whether the image signal is an advertisement image signal comprises: generating a motion change pattern based on field images detected during a period of time; and determining that the image signal is an advertisement image signal if the generated motion change pattern is different from a preset motion change pattern. ### Claim 11 (depends on 8) The control method according to claim 8, wherein the determining whether the image signal is a film image signal comprises: calculating a summed absolute difference between pixel values of neighboring field images among field images detected during a period of time; generating a motion change pattern based on the calculated summed absolute differences; and determining whether the generated motion change pattern is a preset motion change pattern. ### Claim 12 (depends on 8) The control method according to claim 8, wherein the determining whether the image signal is a film image signal comprises: generating a motion change pattern based on field images detected during a first period of time; and determining whether the generated motion change pattern is a preset motion change pattern. ### Claim 13 (depends on 12) The control method according to claim 12, further comprising: generating a motion change pattern based on field images detected during a second period of time longer than the first period of time; determining that the image signal is an advertisement image signal if the generated motion change pattern is different from a preset motion change pattern; and removing the stored image signal corresponding to the advertisement image signal if the image signal is determined to be an advertisement image signal. ### Claim 14 (depends on 13) The control method according to claim 13, wherein the generating a motion change pattern based on field images detected during a second period of time longer than the first period of time comprises: buffering the field images for the second period of time. ### Claim 15 (depends on 13) The control method according to claim 13, wherein the first period of time has a length of 0.3 to 0.5 seconds and the second period of time has a length of thirty to ninety seconds. ### Claim 16 (depends on 8) The control method according to claim 8, further comprising: ending the storing of the image signal if the image signal is determined not to be a film image signal for a predetermined time after the image signal is stored. ### Claim 17 (depends on 8) The control method according to claim 8, further comprising: receiving the image signal by the broadcasting processing apparatus; and determining whether the received image signal is an interlaced image signal, wherein the image signal is not stored if the received image signal is determined to be an interlaced image signal and wherein the image signal is stored only if the received image signal is determined not to be an interlaced image signal.
