BACKGROUND1. Field
Example embodiments of inventive concepts relate to mobile electronic devices, for example, to a mobile electronic device having a content transmission interface that may be connected directly to an external display device.
2. Description of the Related Art
As digital multimedia content has come into widespread use, various types of mobile electronic devices, e.g., mobile phones, portable multimedia players (PMPs), MP3 players, and digital cameras, which are capable of reproducing digital multimedia content have become widely spread. However, such mobile electronic devices include relatively small-sized displays, which may inconvenience users watching content on such mobile electronic devices. Accordingly, various content transmission interface methods have been introduced in order to connect a mobile electronic device to an external display device, e.g., a monitor or a television (TV), so that a user can watch content on a relatively larger display device indoors. The HDMI (High-Definition Multimedia Interface) is a representative content transmission interface method. The HDMI is advantageous in that high-quality uncompressed data can be displayed securely on a display device based on the HDCP (High-bandwidth Digital Content Protection). However, the HDMI requires an HDMI cable in order to connect two devices to each other, thereby increasing installation costs and causing inconvenience to a user.
SUMMARYExample embodiments of inventive concepts provide a mobile electronic device having a content transmission interface that can be connected directly to an external display device without having to use a cable.
Example embodiments of inventive concepts also provides a mobile electronic device having a content transmission interface for displaying content supplied from an external source device on an external display device while saving power consumption.

The body is configured to store and process the digital content, where the digital content includes high-quality uncompressed video data. The content transmission interface connector includes a male connector configured to be connected directly to an external display device and configured to output the digital content to the external display device.
In example embodiments of inventive concepts, the content transmission interface connector is at least one of a high-definition multimedia interface (HDMI) connector, a D-sub connector, and a digital visual interface (DVI) connector, and the male connector of the content transmission interface connector is inserted directly into a corresponding port of the external display device.
In example embodiments of inventive concepts, the body includes a memory device configured to store the digital content, a processor configured to process the digital content, where processing of the digital content includes decoding and reproducing of the digital content, and a power controller configured to control supply of power to the memory device and the processor.
In example embodiments of inventive concepts, the mobile electronic device further includes a universal serial bus (USB) connector including a male connector configured to be connected to an external source device, wherein the mobile electronic device is configured to transmit data of the external source device to the external display device.
In example embodiments of inventive concepts, the power controller is configured to supply power to the memory device and configured to not supply power to the processor, when the USB connector is connected to the external source device, and the power controller is configured to supply power to both to the memory device and the processor when the content transmission interface connector is only connected to the external display device.
According to example embodiments of inventive concepts, a mobile electronic device for reproducing digital content includes a memory device, a processor, a content transmission interface connector and a central processing unit (CPU).
