ADOBE SYSTEMS INCORPORATED - SAN JOSE CA

International Classification:

H04N 7/15

US Classification:

348 1408, 348E07083

Abstract:

A video conference invitation is sent from a computing device in a first conference room to a second conference room for a video conference. Further, an acceptance of the invitation is received at the computing device. In addition, a list of available devices for video conferencing is retrieved from a device information database. The list of available devices indicates a locally connected device and a remotely connected device. The computing device is connected to the video conference through a platform independent interface. Further, the computing device locally controls operation of the locally connected device through a platform independent interface during the video conference and remotely controls operation of the remotely connected device during the video conference.

Abstract:

A speech analyzer and synthesizer system using a sinusoidal encoding and decoding technique for voiced frames and noise excitation or multipulse excitation for unvoiced frames. For voiced frames, the analyzer transmits the pitch, values for a subset of offsets defining differences between harmonic frequencies and a fundamental frequency, total frame energy, and linear predictive coding, LPC, coefficients. The synthesizer is responsive to that information to determine the harmonic frequencies from the offset information for a subset of the harmonics and to determine the remaining harmonics from the fundamental frequency. The synthesizer then determines the phase for the fundamental frequency and harmonic frequencies and determines the amplitudes of the fundamental and harmonics using the total frame energy and the LPC coefficients. Once the phase and amplitudes have been determined for the fundamental and harmonic frequencies, the synthesizer performs a sinusoidal analysis. In another embodiment, the remaining harmonic frequencies are determined by calculating the theoretical harmonic frequencies for the remaining harmonic frequencies and grouping these theoretical frequencies into groups having the same number as the number of offsets transmitted.
