Zusammenfassung:	Video may be provided at a display unit using an encrypted transport stream of a content file. During normal play operation, a plurality of transport stream packets of the encrypted transport stream may be received, where a packetized elementary stream of video frame packets including independently coded and dependently coded video frame packets is multiplexed onto the encrypted transport stream. Payloads of transport stream packets including data of independently coded video frame packets may be selectively decrypted without decrypting payloads of transport stream packets not including data of independently coded video frame packets. The independently and dependently coded video frame packets from the payloads of the transport stream packets may be decoded using the selectively decrypted payloads of the transport stream packets, and the decoded video frame packets of the independently and dependently coded video frame packets may be provided for display.
