摘要:
A method of encrypting a motion picture file and a method of digital rights management using the same, wherein encryption method includes: extracting information on the location of at least one video sample, which is a real-time streaming unit, from meta-data of the motion picture file; extracting the video samples based on the location information; encrypting the extracted video samples, excluding a start code within a video sample header of each extracted video sample, based on predetermined encryption information; and producing an encrypted motion picture file by recombining the encrypted video samples. Since the file is encrypted in units of video object planes (VOPs) while maintaining an MEPG-4 file format, the encryption method can be easily applied to a completed file format and streaming service is also possible.

Provided is a chip on film (COF) type semiconductor package. The COF type semiconductor device includes a flexible film, an electrode pattern formed on the flexible film, a semiconductor device disposed on the electrode pattern, a conductive pad disposed between the electrode pattern and the semiconductor device to electrically connect the semiconductor device with the electrode pattern, and a first protective layer which seals the conductive pad and the semiconductor device and is formed on a portion of the electrode pattern and the semiconductor device. The first protective layer includes a heat conductive material for dissipating heat generated from the semiconductor device.
