A method of managing communications between communication devices within a digital intercom system includes providing input and output tables for each communication device. The tables for each device are made up of cells formed from linear arrays corresponding to communication channels and the other devices. When two devices communicate on a given channel, a cell in the appropriate input and output table is identified based on the channel and the devices communicating. The cells provide volume control information which can be relied upon to determine if or to what degree audio signals should be transferred between the devices.

A method and apparatus for voice transmission and reception by a browser and a voice intercom system are provided. The method for voice transmission by a browser includes: collecting first voice data through a built-in audio collection interface of the browser (S101); obtaining a first voice sampling parameter that can be utilized by a target device (S102) to process voice data; sampling the first voice data based on the first voice sampling parameter to obtain target voice data (S103); and transmitting the target voice data to the target device (S104). The method enables a browser to have a function of voice intercom without using a plug-in.

A digital intercom system has a master station with hardware and software configured to allow duplex communication between a plurality of communication devices. The software is configured to run a plurality of settings for directing communication between the communication devices, the settings including a plurality of channels for each communication device. The channels each define parameters for how the communication devices within the system will communicate. An audio output device is linked to a corresponding communication device of the plurality of communication devices such that the audio output device is configured to receive and play the same audio as the corresponding communication device. The master station is configured to modify the settings based on input entered into a browser based program run on an input/output (I/O) device by a user.

An overlay network platform facilitates a multi-party conference. End users participate in the conference using client-based web browser software, and using a protocol such as WebRTC. According to this disclosure, an enhanced audio experience for the conference is providing by collecting and correlating microphone data from multiple co-located clients, and then constructing (at the platform) a three-dimensional (3D) sound profile of the room in which the clients are co-located. By processing in the platform (as opposed to locally at each client), the approach enables platform-side creation of an ad-hoc, high quality microphone array that identifies the relative positions and orientations of the microphones that are being used by the clients. Individual audio streams received from the microphones are combined, and the relative position information (of the individual microphones) is used to render a single audio stream that represents a high quality recording of the audio in the common physical space. Other clients in the conference request, receive and play back this high quality stream to obtain a high-fidelity 3D representation of the audio as if they are physically present in the room.

A method for presenting information contained in messages in a terminal (MS). In the method, the message includes at least one component. The message is transmitted to a terminal (MS) in a system for transmitting multimedia messages. In the method, a presentation model (SMIL) is formed to contain information related to the presentation of each component attached in the message. The aforementioned presentation model (SMIL) is supplemented with a reference about the location of each component in the message, and the aforementioned presentation model (SMIL) is attached to the aforementioned message.
