An information processing apparatus includes circuitry configured to receive a manifest file for a content stream, the manifest file including a manifest file update mechanism indicating one or more ways of receiving an update to the received manifest file. The circuitry is also configured to receive a manifest file update through the manifest file update mechanism indicated by the received manifest file. The manifest file update indicates that early termination of content during a period in the content stream is possible. The circuitry is also configured to send a request for the content associated with the period to a server based on the manifest file update, and receive the content from the server. The circuitry is also configured to output the content for display during the period and terminate the content early based on the manifest file update.

A computer implemented method is provided for streaming media from a media server to a client web application running in a client web engine. The method involves, by the client web application, initiating a programmable network proxy in the client web engine. The method further comprises, by the programmable network proxy, intercepting a request from the client web application to retrieve the streaming media from the media server and/or intercepting a response comprising the streaming media from the media server. The method further includes, by the programmable network proxy, performing at least one of: i) injecting metadata into the intercepted request; ii) extracting metadata from the intercepted request; iii) injecting metadata into the intercepted response; and iv) extracting metadata from the intercepted response; and respectively forwarding the intercepted request to the media server and/or forwarding the intercepted response to the client web application.

A telephone call is elevated to a virtual meeting while maintaining the telephone call as an audio channel of the virtual meeting for an audio-only caller. During a telephone call, one of the participants of the telephone call requests to switch the telephone call to a virtual meeting. To enable an audio-only caller participating in the telephone call to switch to the virtual meeting, a message is transmitted to the phone device of the audio-only caller. Responsive to an interaction with the message at the phone device, the phone device is connected to the virtual meeting in which the telephone call is maintained as the audio channel at least for the audio-only caller. The specific form and content of the message is based on whether a client application associated with a web service used to implement the virtual meeting is installed on the phone device.

Methods, apparatus, systems, storage media, etc., to perform media monitoring for mobile platforms using messaging associated with adaptive bitrate streaming are disclosed. An example media platform disclosed herein is to detect an adaptive bitrate streaming uniform resource locator (URL) in an outgoing message to be sent by the mobile platform to stream media in accordance with an adaptive bitrate streaming protocol, and associate the adaptive bitrate streaming URL with a time value. The disclosed example media platform is also to transmit the outgoing message to a first server to cause the media to be streamed to the mobile platform, and transmit the adaptive bitrate streaming URL and the time value to a second server different from the first server to cause a media impression associated with the mobile platform to be monitored.

Systems and methods are provided for establishing a video conference session. The systems and methods may include receiving, from a first conference client device, a request to establish a conference session with a second conference client device; determining a first media router for forwarding, to the second conference client device, a media data stream with predetermined attributes of a plurality of first media data streams generated by the first conference client device; determining a second media router for forwarding, to the first conference client, a media data stream with predetermined media attributes of a plurality of second media data streams generated by the second conference client device; and transmitting, to the first conference client device, a first address associated with the first media router and a second address associated with the second media router.
