Abstract
A video receiver receives a compressed 3D video comprising a base view video and an enhancement view video. The base view video and the enhancement view video are encrypted using same encryption engine and buffered into corresponding coded data buffers (CDBs), respectively. The buffered base view and enhancement view videos are decrypted using same decryption engine corresponding to the encryption engine. The decrypted base view and enhancement view videos are decoded for viewing. The video receiver is also operable to encrypt video content of the received compressed 3D video according to corresponding view information and/or coding layer information. The resulting encrypted video content and unencrypted video content of the received compressed 3D video are buffered into corresponding CDBs, respectively. The buffered encrypted video content are decrypted and are decoded together with the buffered unencrypted video content of the received compressed 3D video for reviewing.
