DVD PLAYER THAT SETS OPTIMAL DISPLAY ENVIRONMENT AND OPERATING METHOD THEREOF

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.
