    摘要: A method of providing video content, the method comprising generating a basement layer and a plurality of enhancement layers by performing scalable video coding on a piece of video content; encrypting the basement layer and the plurality of enhancement layers by using different encryption keys, respectively; and transmitting one of the encryption keys to the second device, together with a video content package that comprises the encrypted basement layer and enhancement layers. The encryption keys include a random encryption key generated randomly and chain encryption keys generated sequentially by performing a Hash function on the random encryption key at least one time.

    摘要: A camera video processing/producing method and apparatus is provided. In the camera video processing method, an aspect ratio of a captured image is determined, and a horizontal/vertical image is rotated according to the display orientation of a preview screen of a camera according to the determination result. The rotation information of the horizontal/vertical image is set in a codec parameter, and the codec parameter and the image are encoded.
