Abstract

A content processing apparatus is provided. The content processing apparatus includes an input unit which receives high resolution content, a data processor which generates a video frame by processing the high resolution content, and a controller which, if an output resolution of a display panel, which is to display the video frame, is lower than the resolution of the high resolution content, controls the data processor to form an object corresponding to the high resolution content as an object for low resolution and add the object for low resolution to the video frame.

First claim

What is claimed is:

1. A content processing apparatus comprising:
an input unit which receives high resolution content;
a data processor which generates a video frame by processing the high resolution content; and
a controller which determines an output resolution of a display panel based on display characteristic information, and in response to the output resolution of the display panel, which is to display the video frame, being lower than a resolution of the high resolution content, controls the data processor to form an object corresponding to the high resolution content as an object for low resolution and add the formed object for low resolution corresponding to high resolution content to the video frame to be displayed with the video frame,
wherein the display characteristic information comprises information regarding at least one of the output resolution of the display panel provided in display apparatus, a pixel count, a display size, a viewing distance, and an apparatus model name.

2. The content processing apparatus as claimed in claim 1 , further comprising:
a driver which, if a recording medium on which the high resolution content is recorded is mounted, detects the high resolution content from the recording medium; and
an interface which, if the content processing apparatus is connected to a display apparatus, receives display characteristic information of the display apparatus and provides the display characteristic information to the controller, and provides the video frame to which the object for low resolution is added to the display apparatus,
wherein the input unit receives the high resolution content detected by the driver.

3. The content processing apparatus as claimed in claim 2 , wherein the recording medium stores high resolution content, type information indicating a type of the high resolution content, a first object, a first navigation program or first navigation information informing that the first object is the object for high resolution, a second object, and a second navigation program or second navigation information informing that the second object is the object for low resolution,
wherein the first object and the second object comprise at least one of a subtitle and a content menu.

4. The content processing apparatus as claimed in claim 3 , wherein the data processor comprises:
a scaler which scales down the video frame of the high resolution content; and
a mixer which selectively detects one of the first object and the second object and mixes the detected object with the scaled down video frame,
wherein, if it is determined that the output resolution of the display panel is lower than the resolution of the high resolution content based on the display characteristic information, the controller controls the data processor to scale down the video frame of the high resolution content, to detect the second object according to the second navigation program or second navigation information, and to add the second object to the scaled down video frame.

5. The content processing apparatus as claimed in claim 2 , wherein the recording medium stores the high resolution content, type information indicating a type of the high resolution content, the object for high resolution, and address information on a server apparatus which provides the object for low resolution.

6. The content processing apparatus as claimed in claim 5 , further comprising
a communication unit which accesses the server apparatus according to the address information,
wherein the data processor comprises:
a scaler which scales down the video frame of the high resolution content;
an object storage which stores an object for low resolution received from the server apparatus; and
a mixer which detects whether the object for low resolution is recorded on the recording medium or stored in the object storage, and mixes the detected object for low resolution with the scaled-down video frame,
wherein, if it is determined that the output resolution of the display panel is lower than the resolution of the high resolution content based on the display characteristic information, the controller controls the communication unit to access the server apparatus using the address information and receive the object for low resolution,
wherein, after the object for low resolution is received and stored in the object storage, the controller controls the data processor to scale down the video frame of the high resolution content and add the object for low resolution stored in the object storage to the scaled-down video frame.

7. The content processing apparatus as claimed in claim 2 , wherein the recording medium stores the high resolution content, type information indicating a type of the high resolution content, an object for high resolution, and object output mode information indicating whether scaling control is to be performed with respect to the object for high resolution.

8. The content processing apparatus as claimed in claim 7 , wherein the data processor comprises:
a first scaler which scales the video frame of the high resolution content;
a second scaler which scales the object for high resolution; and
a mixer which mixes the video frame which is output from the first scaler and the object which is output from the second scaler,
wherein, if it is determined that the output resolution of the display panel is lower than the resolution of the high resolution content based on the display characteristic information and if it is determined that the scaling control is allowed based on the object output mode information, the controller controls the data processor to scale down the video frame of the high resolution content, to scale the object for high resolution according to a scaling ratio which is determined based on a display size and an object size of the display panel, and to mix the scaled object with the scaled down video frame.

9. The content processing apparatus as claimed in claim 1 , further comprising:
a receiver which receives a signal comprising the high resolution content through a broadcasting network and inputs the signal to the input unit; and
a display which comprises the display panel and displays the video frame to which the object for low resolution is added.

10. A method for processing content, the method comprising:
detecting high resolution content on a recording medium;
determining an output resolution of a display apparatus to display the high resolution content based on display characteristic information;
in response to determining that the output resolution of the display apparatus is lower than a resolution of the high resolution content, generating a video frame by processing the high resolution content, forming an object corresponding to the high resolution content as an object for low resolution, and adding the formed object for low resolution corresponding to the high resolution content to the video frame; and
displaying the video frame and the object for low resolution is added to the display apparatus,
wherein the display characteristic information comprises information regarding at least one of the output resolution of the display panel provided in display apparatus, a pixel count, a display size, a viewing distance, and an apparatus model name.

11. The method as claimed in claim 10 , wherein the recording medium stores high resolution content, type information indicating a type of the high resolution content, a first object, a first navigation program or first navigation information informing that the first object is an object for high resolution, a second object, and a second navigation program or second navigation information informing that the second obj
