Abstract: Aspects of the subject disclosure are directed towards providing contextual information (such as high resolution still images) during an audio or video call. A receiver of the contextual information may send commands to the sending device to specify a desired resolution and frame rate of such images. A receiving user also may determine how to display any video call frames and/or the contextual information on one or more display devices available to the receiving user. Other contextual information such as location-related data by which a user can determine and display a location of the other call participant (or participants) may be transmitted during the call.

Abstract: The claimed subject matter relates to an architecture that can preprocess audio portions of communications in order to enrich multiparty communication sessions or environments. In particular, the architecture can provide both a public channel for public communications that are received by substantially all connected parties and can further provide a private channel for private communications that are received by a selected subset of all connected parties. Most particularly, the architecture can apply an audio transform to communications that occur during the multiparty communication session based upon a target audience of the communication. By way of illustration, the architecture can apply a whisper transform to private communications, an emotion transform based upon relationships, an ambience or spatial transform based upon physical locations, or a pace transform based upon lack of presence.

Abstract: The disclosed functionality enables non-sessions users of an activity session to be provided awareness of the session. The non-sessions users are made aware of the session and can then choose to join (or not join) the session in an ad hoc manner based on the exposed session information. This functionality encourages serendipitous group interactions (or participations) that might not otherwise occur, does not require that all relevant and/or interested people be identified, and removes the overhead of explicitly inviting everyone who might be interested in the activity and managing responses received from each of the users. Rather than requiring an explicit invitation to join as in conventional applications systems, users can implicitly invite friends to join an activity.
