Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing a program and method for streaming a live session. The program and method provide for receiving, from a first device of a first user, indication of first user input provided by the first user with respect to a first data input field of plural data input fields included in a displayed page; determining whether the first user input corresponds to personally identifiable information; causing, when the first user input does not correspond to personally identifiable information, a second device associated with a second user to display the plural data input fields and to display the first user input; and causing, when the first user input corresponds to personally identifiable information, the second device to display the plural data input fields and to mask display of the first user input.

Abstract: Apparatus is described for digitally encoding an input audio signal for storage or transmission. A distinguishing parameter is measure from the input signal. It is determined from the measured distinguishing parameter whether the input signal contains an audio signal of a first type or a second type. First and second coders are provided for digitally encoding the input signal using first and second coding methods respectively and a switching arrangement directs, at any particular time, the generation of an output signal by encoding the input signal using either the first or second coders according to whether the input signal contains an audio signal of the first type or the second type at that time. A method for adaptively switching between transform audio coder and CELP coder, is presented. In a preferred embodiment, the method makes use of the superior performance of CELP coders for speech signal coding, while enjoying the benefits of transform coder for other audio signals.

Abstract: Apparatus is disclosed for digitally encoding an input audio signal, for storage or transmission, comprising: a pitch detector for determining at least a dominant time-domain periodicity in the input signal; a generator for generating a prediction signal based on the dominant time domain periodicity of the input signal; a first discrete frequency domain transform generator for generating a frequency domain representation of the input signal; a second discrete frequency domain transform generator for generating a frequency domain representation of the prediction signal; a subtractor to subtract at least a portion of the frequency domain representation of the prediction signal from the frequency domain representation of the input signal to generate an error signal; and a generator to generate an output signal from the error signal and parameters defining the prediction signal. A corresponding decoder is also described.
