A layered-keyframe-based, presentation recording service provides for presentation recording sessions, the recording of presentations, and the creation of presentation videos. A user records with the user's device the document pages and page annotations, as well audio and video streams, that are presented using the device during the course of a presentation recording session. The pages, annotations and video streams are efficiently and separately recorded as keyframes. These keyframes are used as document, annotation and video layers to create layered keyframes. A presentation video is created from the layered keyframes and the recorded audio stream. Users can then playback presentation videos at a time, place and manner that is available to, accessible by and/or convenient to them.

Technology is disclosed for a unified communications service (UCS) that converts an audio call to an online collaboration session where users collaborate using one or more collaboration services while continuing to converse on the audio call without interruption (the 'technology'). The technology enables two or more users, who are engaged in a voice conversation, to start a collaboration service. Collaboration service includes such services as, e.g., file sharing, screen sharing, video conferencing, and whiteboarding. These collaboration services are started without disconnecting the ongoing audio call, and/or leaving any user interface used for that call.

Unified communications for online collaboration

Technology is disclosed for organizing, managing and sharing data files as pages of an online binder ('the technology'). In various embodiments, the technology stores multiple data files received in multiple formats from multiple sources as pages of the online binder. The pages of the online binder are of a common format. The common format allows the pages, that is, the data files corresponding to the pages, to be accessed using a variety of devices regardless of a platform of the devices. The online binder is platform agnostic. The technology provides tools to create notes for the pages of the online binder. The notes can include text annotations, drawings, or audio visual annotations, including a recording of the user actions as presented on the device of the user. The technology provides a collaboration service for sharing the online binder with multiple users asynchronously or in real-time.

A double half latch circuit includes a first stage coupled to receive a local input enable signal on an input of a second logic gate, and a complement of the clock signal on an input of a third logic gate, and further includes a fourth logic gate coupled to generate an intermediate enable signal based on states of the local input enable signal the complement of the clock signal. A second stage includes a fifth logic gate coupled to receive the complement of the clock signal, and a sixth logic gate coupled to receive the intermediate enable signal, and is configured to generate the output enable signal. The double half-latch circuit is transparent to the state changes of the local input enable signal when the clock signal is low and opaque to state changes of the local input enable signal when the clock signal is high.

In one embodiment, a presenter device may determine displayed windows of applications, and may provide individual window sharing selectability (e.g., shared or unshared), as well as entire application sharing selectability (shared, unshared, or neither). In particular, the entire application sharing selectability takes priority over individual window sharing selections (i.e., all windows of shared applications are shared and all windows of unshared applications are unshared). Based on individual window sharing selections and entire application sharing selections, a set of presenter device windows that are to be shared with the attendee devices may be determined, as well as a set of unshared windows that are not to be shared with the attendee devices, and the presenter device may share the set of shared windows with the attendee devices, without sharing the set of unshared windows.

The methods and apparatuses detect a color of each of a plurality of pixels within a frame; group a portion of the plurality of pixels having a common color into a block; and generate a color list including the common color based on a threshold value corresponding to the block.

Methods and apparatuses for generating compressed data representing a visual frame

The methods and apparatuses detect a plurality of pixels within a frame; separate a portion of the plurality of pixels into a lossless category based on inclusion of the portion of the plurality of pixels within a color list; and identify a particular pixel as an isolated pixel through a single point identification module wherein the particular pixel is within the portion of the plurality of pixels.
