In the receiver, the encrypted first modification key, the encrypted data key, and the encrypted data are received from the transmitter. The encrypted first modification key is decrypted based on the second modification key, the encrypted data key is decrypted based on the decrypted first modification key, and the encrypted data is decrypted by use of the decrypted data key. | 03-18-2010 |
20100156592 | Television Theft Deterrence - A signal received by a television over a communication medium is interrogated for the presence of a remotely transmitted ping. The television is operated in response to detection of the presence of the ping in the received signal. The television is locked against use in response to failing to detect the presence of the ping in the received signal. | 06-24-2010 |
20110134274 | CAMERA, ENCODER, AND MODULATOR IN SAME ENCLOSURE - An RF signal source having a camera that provides a camera output, an encoder that encodes the camera output in a compressed digital format, and a modulator that digitally encodes and modulates the compressed camera output and that provides the digitally encoded, modulated, and compressed camera output as an RF output of the RF signal source. The camera, the encoder, and the modulator may be contained in an enclosure. Additionally or alternatively, the encoder, the modulator, and at least part of the camera may be formed on a semiconductor substrate. | 06-09-2011 |
20110205434 | REMOTE JACK PACK - A remote jack pack has a video input jack that receives a video signal, an audio input jack that receives an audio signal, a video output that transfers the video signal to a television, an audio output that transfers the audio signal to the television, and a control output that automatically supplies control signals to the television. The control signals indicate the availability of the video and audio signals for processing by the television. The television has a tuner that supplies video and audio signals of a selected channel, a video connector that receives video from the remote jack pack, an audio connector that receives audio from the remote jack pack, a control connector that receive control signals from the remote jack pack, and a processor that is responsive to the control signals to selectively control display of the video and audio signals from the tuner and the video and audio signals from the video and audio connectors. | 08-25-2011 |
20120270509 | Bonding of Receiver to Camera Based Mobile Device Having Connectivity - A mobile device is bonded to a controllable device by reading a code on the controllable device, banding the mobile device to the controllable device by use of the code, and transmitting a remote control signal from the mobile device to control a controllable function of the bonded controllable device so that only the bonded controllable device responds to the remote control signal by performing the controllable function. | 10-25-2012 |
20130227619 | Wireless Network Antenna Apparatus and Method - An antenna for broadcast television programming includes a tuner and demodulator located with the antenna to generate a demodulated television program stream. A network interface is connected to the tuner and demodulator to provide the television program stream to a network, preferably a wireless network. A television set located remotely from the antenna receives the television program stream via the network and displays the program. A portable control device may be connected to the network. Reception of the broadcast programming is improved by controlling the directionality of the antenna in response to the demodulated signal. A service provider may poll the wireless network antenna to determine which broadcast programs are received and may provide extended programming television programs to the user by an internet connection to the user's network. | 08-29-2013 |
20140375823 | DIAGNOSTICS SYSTEM FOR REMOTELY LOCATED TELEVISIONS - In a central television diagnostics system, a plurality of remotely located televisions are connected to a central television distribution facility. The remote televisions each have a microprocessor receiving signal quality values and a memory for storing the quality values. One of the quality values comprises a base line measurement value and another comprises a current measurement value. The microprocessor selectively displays on a display of said television a history of said measurement values upon command by a user or service technician desiring to diagnose the status of signal quality at said television. | 12-25-2014 |
