A satellite IRD (Integrated Receiver Decoder) complies with DiSEqC protocol and is capable of receiving a program of a specific channel from a single cable interface device through a cable. The DiSEqC transmitter transmits a first command corresponding to the specific channel to the single cable interface device through the I/O interface and the cable. The DiSEqC receiver acquires a second command transmitted on the cable through the I/O interface in response to the DiSEqC transmitter transmitting the first command. The detecting circuit compares the second command with the first command to generate a comparison result. The DiSEqC receiver monitors the I/O interface in response to the comparison result indicating that the first command and the second command are different to determine whether there is a command other than the first command transmitted on the cable.

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 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.

Optical devices and cognitive prosthetics based on novel components for enhanced human vision, selective video/television display, digital processing and/or unique image analysis to modify the image that a user sees and significantly improve the perception of that user are disclosed. What the user sees is responsive to specific perceptual and informational needs of the user in real time. Devices from the parent patents are herein made both more useful in practical day-to-day use and are more widely applicable to improving the ability of a user to perceive visual stimuli.

A communication system and a family of methods for remote access to personal television service are disclosed. According to this invention, a remote personal TV service center provides centralized program guide information. A user may access to the personal TV service center through a digital video recorder which is connected to the personal TV service center via telephone modem or a network server. A user may access to the personal TV service center through a remote computer terminal or a personal digital assistant which is connected to a computer network. The user selects program events and programs the digital video recorder by using a graphical user interface installed in the front panel of the digital video recorder in case of local programming, or using a similar GUI which is incorporated into the Web pages presented to remote users by a Web server in case of remote programming. The media stream stored in one digital video recorder may be transferred to another digital video recorder. For data security protection during data transfer, all communication are authenticated and encrypted.

Methods and devices for improving visual perception in challenging vision environments and for some with low vision conditions (including age related macular degeneration, AMD) are disclosed. A plurality of frequently co-pathological conditions that together make undistorted, clear and bright vision challenging are dealt with by managing the nature, amounts and patterns of light reaching the eyes while managing the sensitivity and dynamic ranges of the eyes. For example, the sensitivity of chromophore response to particular wavelengths and the instant status of the visual transduction system are, in some embodiments, measured, monitored and managed.

Optical devices based on novel components for selective video/television display, digital processing and/or unique image analysis to modify the image that a user sees and significantly improve the perception of that user are disclosed. What the user sees is responsive to specific perceptual and informational needs of the user in real time. Devices from the previous (parent) patents are herein made both more useful in practical day-to-day use and more widely applicable to improving the ability of a user to perceive visual stimuli.

A portable media content device for providing media content to remote devices external to a home network, the portable media content device may include a processor in communication with a memory configured to maintain media content, and a transceiver. The processor may be configured to recognize a home network provided at a first location, instruct the transceiver to transmit a media request to an in-home media recorder connected to the home network and at the first location, receive, in response to the media request, media content from the media recorder and to store the media content in the memory.
