摘要： A DVD player which is capable of automatically setting an optimal display environment for a digital TV by referring to screen ratio and resolution information received from the digital TV, and an operating method thereof. The method involves first issuing a request for display environment setting information to the digital TV using a predetermined channel of the communication cable and receiving the requested information from the digital TV using the predetermined channel once communications between the DVD player and the digital TV are initiated. The method then involves converting signals reproduced from a DVD based on the received display environment setting information such that the signals are compatible with the digital TV, and then outputting the converted signals to the digital TV using the communication cable.

摘要： A digital interface system to display an inappropriate connection state of a digital interface (High-Definition Multimedia Interface (HDMI) in an HDMI connection supporting an Ethernet function and a cable connection state displaying method therefore. When a user intends to use the Ethernet function by connecting the HDMI cable, the inappropriate connection of the HDMI cable is displayed on a screen by a message or a diagram. Also, in case of a plurality of connected HDMI cables, the position of an inappropriate HDMI cable is indicated on the screen. Even though it is difficult to distinguish a general HDMI cable from an HDMI with HDMI Ethernet and Audio Return Channel (HEAC) cable, an inappropriate HDMI cable connection is accurately identified.

摘要： A method for encrypting content includes using a plurality of different encryption schemes to produce encrypted content. Encryption information is provided so as to indicate which of the plurality of different encryption schemes is used on portions of the content that was encrypted. Encryption information and the encrypted content are both sent as a content stream to another device. The decryption involves using the encryption information to help control the decryption so that the correct one of a plurality of different decryption schemes is applied to the proper portions of the encrypted content.

摘要： A DVD reproducing device is capable of being connected to a certain external electronic device. The DVD reproducing device includes an external input receiving unit connected with the external electronic device to receive an external input signal from the external electronic device. A key input receiving unit receives a user selection signal for selecting whether or not the external input signal is transformed. An external signal processing unit transforms the external input signal into a certain form according to a user selection signal. A control unit controls the external signal processing unit such that when an external input signal is received through the external input receiving unit, a received signal is transformed into a signal form predetermined by a user selection signal; and a signal output unit outputs the external input signal transformed at the external signal processing unit, whereby a signal inputted from the external electronic device is transformed into an optimal form to be displayed on the video display device.
