A robust, computationally-efficient and secure system is described for streaming content from a server to a client device via the Internet or another digital network. Various aspects relate to automated processes, systems and devices for securing a media stream with efficient yet effective digital cryptography. In particular, content may be transmitted in transport stream (TS) format in which all packets are encrypted (e.g., using a cipher block chain), in which control packets are exempted from encryption (e.g., using an electronic codebook), or in any other manner.

Performance evaluation of a storage device, for example a storage device connected to a Set Top Box, for evaluating its suitability for supporting DVR/PVR functions such as recording a broadcast audio/video stream or time shifting a broadcast audio/video stream.

Systems, devices and automated processes provide robust, computationally-efficient and secure protection of media content or other electronic data stored on a user-supplied storage device through the use of efficient file system encryption. Only certain portions of the content are encrypted by the host device, thereby reducing the computational demand in comparison to encrypting all of the content. By selecting the particular portions to encrypt, the formatting and structure of the stored data can be concealed, thereby making the use of the unencrypted content very difficult, if not impossible. In implementations based upon the XFS file system, for example, the superblocks that store header information about the files stored on the drive can be encrypted, thereby rendering the unencrypted content

A recording control apparatus that records data on a recording medium includes a position recording unit configured to perform control so that, upon completion of recording of data, a recording start position for next recording of data is recorded on the recording medium, an initialization unit configured to initialize the recording medium, and a control unit configured to perform control in such a manner that in a case where the initialization unit executes first initialization processing, the first initialization processing and clear processing for clearing the recording start position recorded on the recording medium are executed, and in a case where the initialization unit executes second initialization processing, the second initialization processing is executed without executing the clear processing.

Robust, computationally-efficient and secure systems, devices and automated processes are described for storing content on a disk drive or other storage device that is supplied to a media encoder or other host device. The user-supplied drive may be used, for example, to store content in a digital video recorder (DVR) or the like. The host device creates two separate digital identifiers that separately identify the host device and the user, respectively, so that subsequent pairing can be performed based upon either identifier. The two identifiers are stored on the storage device and rendered upon subsequent pairing for validation by the host device.

Disclosed are a method for controlling a device including at least one memory, and a smart TV. The method comprises the steps of: receiving, from a remote controller, a signal for executing at least one application; outputting video data and audio data of the executed application; temporarily storing the executed application in an internal memory; swapping, to an external memory, a page corresponding to a specific application of the at least one application stored in the internal memory; and displaying information on the application swapped to the external memory.
