A system comprising an audio compression device is provided. The audio compression device receives a plurality of pulse code modulated (PCM) samples, performs a quantization of the plurality of the PCM samples, and determines a plurality of time windows for the plurality of quantized PCM samples. The audio compression device further determines a first number of delta bits and a first sample count for a first time window of a plurality of time windows, where the first time window includes a first group of time-domain consecutive samples according to the first sample count. The audio compression device encodes the sample into the first number of delta bits based on a difference from a previous sample to generate a first stream of delta bits, and encodes the first sample count and the first number of delta bits in a corresponding first header for the first time window.

Audio compression for low overhead decompression

A method, system, server and device are disclosed. According to one or more embodiments, a server is provided. A first audio track is received which includes first audio originating from a premises client at a premises location. A second audio track is received which includes second audio originating from a remote client. A first pan angle is determined for the first audio track and a second pan angle is determined for the second audio track. The second pan angle is different from the first pan angle. A stereo composite track is generated based on the first pan angle and the second pan angle, where the stereo composite track includes the first audio track and the second audio track.

Multi-track audio in a security system

A method is provided in one example and includes receiving a video input from a camera element; using change detection statistics to identify background image data; using the background image data as a temporal reference to determine foreground image data of a particular video frame within the video input; using a selected foreground image for a background registration of a subsequent video frame; and providing at least a portion of the subsequent video frame to a next destination.

System and method for providing enhanced video processing in a network environment

A system and method for reducing blurred video caused by intra-coded IDR-frames sent in response to when a destination endpoint in a multipoint videoconference switches to a new video source. An embodiment according to the invention comprises using inter-coded temporal predictive referencing a long term reference frame (LTRF) instead of IDR-frames in a multipoint videoconference system.

Video switching without instantaneous decoder refresh-frames

A method is provided in one example and includes receiving an input video, and identifying values of pixels from noise associated with a current video image within the video input. The method also includes creating a skip-reference video image associated with the identified pixel values, and comparing a portion of the current video image to the skip-reference video image. The method also includes determining a macroblock associated with the current video image to be skipped before an encoding operation occurs.

System and method for skip coding during video conferencing in a network environment

A method, and apparatus, and logic encoded in one or more computer-readable media to carry out a method. The method is to sample analog video at a sample clock rate and at a phase selected from a set of phases based on a quality measure determined from the sampled video. The quality measure is based on statistics of pixel to pixel differences in a coordinate of the generated digital video that have a magnitude exceeding a pre-determined threshold.

Phase determination for resampling video

The invention disclosed is a system for playing a music sequence such as a MIDI file in synchronization with a prerecorded digital audio data file, such as an MP3 file. The synchronization is accomplished by using the digital media sample rate as a common time base for progression of the playing of the digital media and the music sequence.

Method and apparatus for playing in synchronism with a digital audio file an automated musical instrument

The invention disclosed is a system for playing a music sequence such as a MIDI file in synchronization with a prerecorded CD. The synchronization is accomplished by using the digital media sample rate as a common time base for progression of the playing of the digital media and the music sequence.

Method and apparatus for playing in synchronism with a CD an automated musical instrument

The invention disclosed herein is a system and method for playing music sequences, such as MIDI files in synchronization with a DVD. This system utilizes a preauthored music sequence and a controller that listens to the S/PDIF output of a DVD player. Further, this application discloses a method for creating MIDI files for use with the invention disclosed herein.

Method and apparatus for playing in synchronism with a DVD an automated musical instrument

Described herein are methods and systems for conducting computer system communications with a number of different devices that communicate with the computer system in a number of different protocols via a protocol-shared combination host controller. Combination host controller has a reduced set of pins for handling communication in a plurality of communication protocols. The total number of pins needed for driving communication in a plurality of communication protocols is reduced by sharing at least one control pin or at least one data pin or combination thereof between at least some of the plurality of communication protocols. In one embodiment, data communications in different protocols overlapping in time can be interleaved onto to a shared data path by suspending a current transmission until a later higher priority transmission is complete.
