Abstract: A method and system to enable autonomous processing of a command line string prevent risky operations. After receiving a command, a session control service and holds the command in a queue while the command is parsed and risk analyzed. The parsed command and its parameters are sent to an AI-driven command risk analyzer trained on the types of commands that represent risks and generate a risk score. The risk score is used to inform the session control service to allow the command to be presented to the asset for execution if the risk has a low score and if the risk has a high score, either a) block the command execution or b) send the command and risk analysis to an admin user or approval team for review and either approval or rejection of the command.

Abstract: A method for communicating data, such as audio/video (AV) data, over plural channels involves selecting data and encryption information, and encrypting the data with the encryption information to thereby produce encrypted data. The encryption information is broken into portions. The encrypted data is communicated by way of at least one of the plural channels, and at least some portions of the encryption information are communicated over at least one channel other than that one over which the encrypted data is communicated. In a more general case, the encrypted data is sent over one channel, and the encryption information is divided and sent over several other channels.

Abstract: Independent first and second information signals (content1 and conten2) are transmitted over separate independent physical channels to a receiving location. Security is provided by encoding (12a) at least the first information by means of the second information to produce encoded signals (1?, . . . N?). The encoded signals and the second signals are received from the first and second channels at the second location (230). The encoded first signals are decoded at the receiving location by processing with the second signals. In some embodiments, the second information signals are encoded by processing with the first information signals. In a more general case, plural channels of information are “cross-encoded” by the information in plural other channels, and the plurality may be large.

Abstract: The disclosed embodiments relate to a digital radio frequency (RF) circuit that creates a signal in a desired range in a frequency spectrum. The RF circuit comprises circuitry that produces a first sample data modulated signal having a first frequency and a first sample data clock rate. An up-sampler modulator receives the first sample data modulated signal and produces a second sample data modulated signal having a second frequency and a second sample data clock rate. The RF circuit may also comprise circuitry that receives the first sample data modulated signal and the second sample data modulated signal and delivers one of the first sample data modulated signal and the second sample data modulated signal for further processing depending on which sample data modulated signal exhibits desirable characteristics for a given operating environment.

Abstract: A digital radio frequency (RF) transceiver circuit comprises circuitry that is adapted to select between a transmitter input signal (148) and a receiver input signal. A plurality of filters are adapted to receive either the transmitter input signal or the receiver input signal and to produce either a filtered transmitter signal or a filtered receiver signal. Circuitry alternatively receives the filtered transmitter signal or the filtered receiver signal and produces a modulated output and a demodulated output.

Abstract: An adaptive digital image processor precedes an MPEG2 encoder. The processor receives a high definition video signal intended for broadcast or storage, and adaptively low-pass filters the signal. The signal is subjected to low-pass two-dimensional filtering to eliminate encoding artifacts and related noise. The video signal is then horizontally down-sampled to create a lower resolution hybrid signal. A receiver decodes and decompresses the hybrid signal. The hybrid signal is upsampled to its original resolution using existing hardware and software with a software modification.

Abstract: There is provided a method for enabling wireless reception of return channel signals in a satellite communications system having at least one satellite and a plurality of subscribers. A system time reference is transmitted to the plurality of subscribers for establishing a precision frequency reference that is based on the system time reference. Return channel signals are wirelessly received from the plurality of subscribers using a carrier frequency synthesized from the precision frequency reference established from the system time reference.

Abstract: A multi-channel signal receiver enables, among other things, a plurality of frequency channels to be simultaneously tuned so that broadcast channel programs included within the frequency channels may be simultaneously accessed. According to an exemplary embodiment, the multi-channel signal receiver includes a signal source operative to generate digital information representing a plurality of broadcast channel programs. Signal processing circuitry including a filter bank is coupled to the signal source, and is operative to simultaneously provide base band signals corresponding to the plurality of broadcast channel programs.
