The present invention is directed to providing systems and methods for remotely monitoring sites to provide real time information which can readily permit false alarms to be distinguished, and which can identify and track the precise location of an alarm. In exemplary embodiments, monitoring capabilities such as intrusion/fire detection and tracking capabilities, can be implemented through the use of multistate indicators in a novel interface which permits information to be transmitted using standard network protocols from a remote site to a monitoring station in real-time over preexisting communication networks, such as the Internet. A wireless network can also be established using browser encapsulated communication programs (for example, active X control, Java applets, and so forth) to transmit data packets which comply with any standard wireless local area network protocol. Communications can thereby be established between a web server embedded in a centrally located host monitoring station and a separate security panel deployed in each of the buildings to be remotely monitored. In exemplary embodiments, communications can be handed off from the centrally located host monitoring station to a mobile monitoring station (for example, to a laptop computer in a responding vehicle, such as a police or fire vehicle). The handoff can be such that direct communications are established between a security panel site being monitored and the laptop, or over, for example, a cellular network or indirect communications can be established via the host monitoring station.

Representations of spatial audio scenes using higher-order Ambisonics HOA technology typically require a large number of coefficients per time instant. This data rate is too high for most practical applications that require real-time transmission of audio signals. According to the invention, the compression is carried out in spatial domain instead of HOA domain. The (N+1)² input HOA coefficients are transformed into (N+1)² equivalent signals in spatial domain, and the resulting (N+1)² time-domain signals are input to a bank of parallel perceptual codecs. At decoder side, the individual spatial-domain signals are decoded, and the spatial-domain coefficients are transformed back into HOA domain in order to recover the original HOA representation.

In general, this disclosure describes techniques of determining a backset for client devices attempting to download data of a live transmission. A backset is an amount of temporal delay that the client devices are delayed by when viewing the live transmission. As described herein, a media content provider may determine a recommended backset for each client devices based characteristics of the client device. Each client device may then be backset by the determined value, or may calculate its own backset based on the recommended backset. Establishing a backset for each client device may avoid rebuffering of live transmission data.

A speech-to-text-to-speech for use with on-line and real time transmission of speech with a small bandwidth from a source to a destination. A speech is received and broken down to phonemes, which are encoded into series of symbols compatible with communication systems and other than a known symbolic representation of the speech in a known language for being transmitted through communication networks. When received, the series of symbols is decoded to restore the phonemes and for reconstituting a speech according to the phonemes prior to being communicated to a listening party.

Methods, medium, and handheld, wireless devices which compress, enhance, encode, transmit, decompress and display digital video images in real time. Real time wireless videoconferences connect multiple handheld video devices. Real time compression is achieved by sub-sampling each frame of a video signal, filtering the pixel values, and encoding. Real time transmission is achieved due to high levels of effective compression. Real time decompression is achieved by decoding and decompressing the encoded data to display high quality images. A receiver can alter various setting including but not limited to the format for the compression, image size, frame rate, brightness and contrast. A zoom control can be used select a portion of interest of video being transmitted or being played back.

A medium streaming distribution system reduces effects of packet loss in a network before the packet reaches radio base station. A medium distribution device for packet-transmits via the base station, a medium stream to the network by a real time transmission protocol. A packet analyzer monitors the packet arriving at the radio base station and transmits feedback Information associated with loss of a packet to the medium distribution device. Based on the feedback from a relay device and a terminal device of the medium stream, the transmission rates from the medium distribution device to the relay device and from the relay device to the terminal device are obtained to provide a greater transmission rate in a surplus band for re-transmission or a forward error correction.

A system and method for real time transmission of variable bit rate MPEG video traffic with consistent quality, wherein each frame is encoded with quantization parameter generated from an encoder rate controller, and encoded data is transmitted to an encoder buffer. Transmission rate about each frame interval is determined by a channel rate controller at the beginning of the frame interval. Data transmission buffered at the encoder buffer is first regulated by Leaky Bucket counter, and the regulated data is transferred to a decoder buffer in a video receiving system through network. The encoder rate controller and channel rate controller included in the VBR video transmission system control the transmission rate generated from the video encoder and that from the network with satisfying imposed constrained conditions, respectively.

A wireless microphone system for use with a mobile digital recording system is disclosed. The wireless microphone system is comprised of a wireless microphone with a built-in transceiver and an in-vehicle transceiver that is connected to a mobile digital recording system.
