摘要： Se proporciona un códec de voz o audio multimodo. El códec de voz o audio multimodo comprende medios para formatear una carga útil para la transmisión de datos de códec de voz multimodo o datos de códec de audio multimodo. Dichos medios están configurados para decidir, basándose en un modo de códec y una velocidad de bits, si se utiliza un formato de carga útil sin cabecera o con cabecera completa. Si se utiliza el formato de carga útil de encabezado completo con un encabezado de carga útil, el encabezado de carga útil comprende información de señalización, en la que la información de señalización está asociada con al menos uno de: una identificación de modo de códec, una tasa de bits, una adaptación de modo, una solicitud de modo de códec, un ancho de banda de audio, un modo interno de códec y agregación de cuadros. Dichos medios están configurados para empaquetar datos de carga útil RTP con o sin el encabezado de carga útil dependiendo de la decisión.

摘要： A method for providing public announcements in a vehicle for public passenger transport, in particular a railway vehicle, includes establishing a wireless data connection between a mobile device 1, which stores a voice message, and an audio system 5, 6 of the vehicle using a signalling protocol for initiating, maintaining, and terminating real-time sessions for voice applications via a VoIP Server 4, transferring the voice message as a VoIP message (VM) from the connected mobile device 1, to the audio system 5, 6 using the signalling protocol, and converting the VoIP message (VM) into the public announcement using the audio system 5, 6. The signalling protocol may comprise session initiation protocol (SIP) and the transfer may use RTP.

摘要： Methods, apparatus, systems and articles of manufacture are disclosed to monitor streaming media content. Example apparatus disclosed herein include means for determining whether a streaming media flag is asserted in a payload of a watermark detected in media presented by a media presentation device, the streaming media flag to indicate whether the media was distributed to the media presentation device as streaming media. Disclosed example apparatus also include means for discarding the detected watermark from collected data in response to a determination that the streaming media flag is asserted. Disclosed example apparatus further include means for reporting the collected data to a remote server via a network.

摘要： A computerized method of delivering data to one or more client computing devices includes receiving, by a server computing device, a data stream starting at a first time: processing, by the server computing device, the data stream, thereby creating a processed data stream; transmitting, by the server computing device, via a wireless network in electronic communication with the server computing device, the processed data stream to the one or more client computing devices: and interpreting, by an application installed on the one or more client computing devices, the processed data stream, thereby recovering the data stream for use by the one or more client computing devices. A latency between the first time and the second time is less than 100 milliseconds.

摘要： This invention relates to a method of processing sensitive information over VoIP. The method provides a method of processing, by a call processor, a media call comprising the steps of: receiving a first signalling stream from a first entity; creating a second signalling stream to a second entity; forwarding signals received from the first signalling stream to the second signalling stream; receiving a third signalling stream from the second entity; creating a fourth signalling stream to the first entity; and forwarding signals received on the third signalling stream to the fourth signalling stream; the first signalling stream containing instructions to set up a media call between the first entity and the second entity such that media is transmitted over a first media stream from the first entity to the second entity and a media is transmitted over a second media stream from the second entity to the first entity without intervention by said call processor.

摘要： Systems and methods for dynamically chunking for delivery instances are provided that automatically implement chunking strategies based on one or more chunking considerations related to a request for a media file. These systems and methods may be part of a larger media servicing network that can be used to, among other things, process uploaded media content, provide it for streaming/downloading, and collect metric information regarding the streaming/downloading. The disclosed systems and methods provide for receiving a request having a Uniform Resource Locator (URL) and providing an index file to implement chunking strategies based on chunking considerations associated with the request.
