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.

Apparatuses, methods, and program products are disclosed for displaying video inputs. One apparatus includes a display, a processor, and a memory that stores code executable by the processor. The code is executable by the processor to receive, by use of the processor, multiple video inputs. The code is executable by the processor to determine display criteria of each video input of the multiple video inputs based on user selection. The code is executable by the processor to display, by use of the display, each video input of the multiple video inputs based on the display criteria of the respective video input.

A method and apparatus for secure transfer of previously broadcasted content enables the secure transfer of previously broadcasted content between DVRs on a computer network.

A multi-component method and device for improving vision for some with low vision conditions including age related macular degeneration (AMD) is disclosed. A plurality of co-pathological conditions that together make undistorted, clear and bright vision challenging are dealt with by managing the nature, amounts and patterns of light provided to the eye in a display embodiment. For example, a worn embodiment, in providing an improved image of the view ahead, modifies the frequency mix of incoming light, the relative intensities of light to different retinal locations and the color perception of the wearer while undistorting certain kinds of progressive distortion.

An apparatus is provided. The apparatus includes a communication unit configured to communicate with a first electronic device, and a control unit operatively coupled with the communication unit, the control unit configured to receive, from the first electronic device via the communication unit, information associated with a playback location of multimedia data, the multimedia data to be presented at a second electronic device operatively coupled with the apparatus, based at least in part on the information, and transmit at least one portion of the multimedia data, to the second electronic device.

A method and apparatus for secure transfer and playback of multimedia content enables the secure transfer of multimedia content from a digital video recorder (DVR) to a personal computer (PC) and further to a handheld device. A DVR determines which devices on a Local Area Network (LAN) are authorized to share and/or retrieve content from the DVR. The DVR receives a connection request from a PC on the LAN, authorizes the connection request and establishes a secure connection between the DVR and the PC. Once the secure connection is established, the DVR receives a request for multimedia content from the PC, prepares the multimedia content for transfer and transfers the multimedia content to the PC.

A program guide system is provided that supports a program guide application and multiple non-guide applications. The program guide system has a program guide application interface that allows the non-guide applications to use both device resources and program guide resources. The application interface maintains a list of registered applications and directs control requests from various applications to the current primary application. The application interface also has a user interface input director that directs keystrokes and other user input commands to the appropriate application. If a keystroke for the program guide application is detected while a non-guide application is running, the program guide application is invoked.
