摘要： A method performed by a network node (110) for enabling a video communication service between two or more user equipments (121-125). The network node (110) receives an indication of the quality rendering capability of the user equipment from each of the user equipments (121-125). The network node (110) also determines a video quality range of the video communication service between the user equipments (121-125), wherein the highest video quality of the range is determined by the highest video quality of the user equipment with the lowest video quality rendering capability and the lowest video quality of the range is determined by the lowest video quality of the user equipment with the highest video quality rendering capability. Then, the network node (110) enables the video communication service based on the determined video quality range. A network node (103) for performing the method is also provided.

摘要： The invention relates to a method, computer, computer program and computer program product for speech quality estimation. The method comprises the steps of: determining a coding distortion parameter (Q COD ), a bandwidth related distortion parameter (BW) and a presentation level distortion parameter (PL) of a speech signal; extracting a first coefficient ( ω 1 ) and a second coefficient ( ω 2 ), the first coefficient and the second coefficient being dependent on the coding distortion parameter; and calculating a signal quality measure (Q), where the signal quality measure is Q COD + ω 1 Bw + (ω 2 . PL , - using the signal quality measure in a quality estimation of the speech signal.

摘要： A multipoint conference unit includes input/output ports to communicate with at least three client terminals via at least three communication channels with each communication channel communicating with one of the at least three client terminals, a memory to store data streams communicated between multipoint conference unit and the client terminals, and a processor to mix data streams received from the client terminals and to store the mixed data streams in the memory. The processor also determines a number of each of three different types of communication channels and selectively implements bandwidth extension to the communication channels based on the determination.

摘要： The present invention relates to a method for improving quality of experience of a real-time communication service. The method is performed in a client configured to receive media from a communication system. The method comprises receiving (210) via a user interface of the client, a request to improve quality of experience through a trade-off between media quality and delay of received media. The method also comprises initiating (220) an action for adjusting the trade-off between media quality and delay of received media in response to the received request. The present invention also relates to the client.
摘要翻译：本发明涉及一种提高实时通信业务经验质量的方法。该方法在被配置为从通信系统接收媒体的客户端中执行。该方法包括经由客户端的用户界面接收（210）通过介质质量和接收到的媒体的延迟之间的权衡来提高体验质量的请求。该方法还包括启动（220）响应于接收到的请求来调整媒体质量和接收到的媒体的延迟之间的权衡的动作。本发明还涉及客户端。
