Abstract: Communication is carried out using devices with user-maintained modes that enable synchronous content sharing and communication. Each user-maintained mode enables a lightweight interface for positioning content in a conversation by initiating and terminating data transmission through user produced feedback to create a shared conversational experience.

Abstract: A system and method for providing multimedia content between a plurality of user terminals is presented. A first multimedia presentation on a first user terminal is selected by a first user. Data corresponding to the first multimedia presentation is transmitted to a second user terminal. Data is received corresponding to a second multimedia presentation from the second user terminal by the first user terminal. The first multimedia presentation or the second multimedia presentation is displayed on the first user terminal and the second user terminal based on, respectively, a first profile of the first user terminal and a second profile of the second user terminal.

Abstract: One embodiment provides a system that forwards a packet with a hierarchically structured variable-length identifier (HSVLI) in a network. An HSVLI indicates a piece of content and indicates a hierarchical structure of contiguous components ordered from a most general level to a most specific level. The length of the HSVLI is not fixed. During operation, the system receives a packet which contains an interest for a piece of content with an HSVLI. Subsequently, the system determines forwarding information for the HSVLI based on one or more of: knowledge of content which matches the HSVLI, a forwarding policy, and contextual information about the network. Next, the system configures a forwarding engine with the forwarding information. The system then forwards the packet based on the forwarding information.

Abstract: A method and apparatus for controlling data transmission via user-maintained modes is provided. A first audio data stream is recorded on a transmitting electronic apparatus. A second audio data stream is stored on the transmitting electronic apparatus. Transmission of one of the first and the second audio data streams is controlled via a first user-maintained mode when at least the other of the first and the second audio data streams is being transmitted to the electronic apparatus. The one of the first and the second audio data streams is transmitted to a receiving electronic apparatus and the other of the first and the second audio data streams is suspended.

Abstract: Apparatus, methods, and a computer-usable storage medium storing instructions that, when executed by a computer, cause the computer to synchronize the presentation of an experiential data stream at a local device with the presentation of a similar experiential data stream using a playback position received over a control link.

Abstract: Apparatus, methods, and program products that enable an audience member of a local device to navigate, by activation of user selectable controls, through an experiential data stream presented on the local device.

Abstract: A method and a computer-usable storage medium storing instructions that, when executed by a computer, cause the computer to perform the method, which provides content to supplement a presentation of an experiential data stream. The method includes a step of receiving a request for content configured to be included in said presentation of the experiential data stream. The method also determines content parameters from the request that are used to select the content. It also provides the content and records appropriate transaction information.

Abstract: The disclosed technology is a computer application that establishes communication between a conversation-finder module and a computer application environment. The conversation-finder module determines a conversational floor based on three or more floor determination inputs. The conversational floor associates at least two of the three or more floor determination inputs as being on the conversational floor. The conversation-finder module and the computer application environment can be responsive to each other and can adapt to each other. That is (either or both), the computer application environment can adapt to the conversational floor(s) determined by the conversation-finder module; and the conversation-finder module can determine the conversational floors responsive to a floor determination input and/or control input from the computer application environment.

Abstract: Apparatus, methods, and a computer-usable storage medium storing instructions that, when executed by a computer, cause the computer to enable a presentation device to automatically accommodate conversations in a social space. This system monitors a first playback position in a time dimension of an experiential data stream on a local device for at least one local audience member, and monitors one or more utterances received by the local device. Then, the system enables the presentation of the experiential data stream in response to the step of monitoring.

Abstract: Apparatus, methods, and a computer-usable storage medium storing instructions that, when executed by a computer, cause the computer to establish a control link, establish a human communication channel, and create a shared social space that enables a local audience member and a remote audience member to simultaneously experience a recorded experiential data stream, whereby the local audience member and the remote audience member are enabled to communicate over the human communication channel about the experiential data stream.

Abstract: Apparatus, methods, and a computer-usable storage medium storing instructions that, when executed by a computer, cause the computer to perform an operation for determining where to position received transitory audio within an experiential data stream of a shared social space so as to provide minimal disruption to the experiential data stream.

Abstract: Apparatus, methods, and a computer-usable storage medium storing instructions that, when executed by a computer, cause the computer to present replacement/additional content in conjunction with an experiential data stream by maintaining a first playback position in the experiential data stream, detect proximity of the first playback position to an insertion coordinate associated with the replacement/additional content, and present content at the insertion coordinate from the replacement/additional instead of from the experiential data stream content.

Abstract: One embodiment provides a system for forwarding packets with hierarchically structured variable-length identifiers (HSVLIs), wherein the computer includes a processor. During operation, the system converts an HSVLI into a number of fixed-length addresses, wherein the HSVLI indicates a piece of content and is hierarchically structured, and comprises contiguous components ordered from a most general level to a most specific level. In addition, the length of a respective HSVLI is not fixed. The system further performs an effective longest-prefix-match lookup by performing multiple exact-match lookups based at least on the fixed-length addresses.

Abstract: One embodiment provides a system that receives a packet with a hierarchically structured variable-length identifier (HSVLI). An HSVLI indicates a piece or collection of content and may be hierarchically structured, comprising contiguous components ordered from a most general level to a most specific level. The length of a respective identifier is not fixed. During operation, the system converts the HSVLI into a fixed-length key. Subsequently, the system obtains forwarding information based on one or more longest-prefix matches with a longest-prefix-match lookup engine using the fixed-length key. Next, the system forwards the packet to an output port based on the forwarding information.

Abstract: A system and method for automatically adjusting floor controls for a conversation is provided. Audio streams are received, which each originate from an audio source. Floor controls for a current configuration including at least a portion of the audio streams are maintained. Conversational characteristics shared by two or more of the audio sources are determined. Possible configurations for the audio streams are identified based on the conversational characteristics. An analysis of the current configuration and the possible configurations is performed. A change threshold is applied to the analysis. When the analysis satisfies the change threshold, the floor controls are automatically adjusted. The audio streams are mixed into one or more outputs based on the adjusted floor controls.
