The present invention will now be described in detail with reference to the figures. FIG. 1 is a functional block diagram illustrating a distributed data processing environment, generally designated 100, in accordance with one embodiment of the present invention.
Distributed data processing environment 100 includes client computing device 120 and server computing device 130, interconnected over network 110. In an exemplary embodiment of the present invention, distributed data processing environment 100 represents a video conferencing environment, where conference participants communicate via a network, such as network 110. Network 110 can be, for example, a local area network (LAN), a wide area network (WAN) such as the Internet, or a combination of the two, and can include wired, wireless, or fiber optic connections. In general, network 110 can be any combination of connections and protocols that will support communication between client computing device 120 and server computing device 130.
Client computing device 120 includes user interface (UI) 122, camera 124, conferencing program 126, playback program 128, and database 129. In various embodiments of the present invention, client computing device 120 can be a laptop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of recording and displaying video and communicating with server computing device 130 via network 110. UI 122 may be, for example, a graphical user interface (GUI) or a web user interface (WUI) and can display text, documents, web browser windows, video, user options, application interfaces and instructions for operation. Client computing device 120 may include internal and external hardware components, as depicted and described in further detail with respect to FIG. 4. Camera 124 may be included as an internal component of client computing device 120 or may be an external camera connected to client computing device 120 via a communication cable, such as a universal series bus (USB) cable. Camera 124 can include motion sensors and required motion sensing technology to communicate with client computing device 120. Camera 124 creates a video link which can allow client computing device 120 to act as a videoconference station when connected to video conference program 132 on server computing device 130.
Conferencing program 126 can be any platform that can host a live video conference on client computing device 120 allowing a user of the client computing device to communicate with participants in the live video conference in other locations by two-way video and audio transmissions. For example, conferencing program 126 may be Lotus Live, Google Hangouts, Facebook video chat, Skype, Google video chat, or any program capable of hosting a video conference on client computing device 120. Conferencing program 126 can connect to other participants in a live video conference using a video conferencing program via network 110, such as video conference program 132 on server computing device 130.
Playback program 128 detects conferencing program 126 has accessed, or joined, a live video conference. Playback program 128 can allow a user to record content, for example, a short video clip, using camera 124, and play the content in the live feed video conference. In an exemplary embodiment of the present invention, playback program 128 prompts a user to record a short video clip. In various embodiments of the present invention, a user may use an existing video clip that is stored in database 129 on client computing device 120. In the exemplary embodiment, playback program 128 records the short video clip of the user, and when prompted, can insert the short video clip into the live video conference accessed via conferencing program 126. In various embodiments of the present invention, playback program 128 may be located elsewhere within distributed data processing environment 100, or may be otherwise accessible to a user of client computing device 120 via network 110, such as a download available on the Internet. Playback program 128 may also be made available as an add-on for conferencing program 126. In various embodiments of the present invention, database 129 may be located elsewhere within distributed data processing environment 100 and can communicate with playback program 128 via network 110.
Server computing device 130 includes video conference program 132. In order to establish a live video conference, at least one other client computing device (not shown) connects to video conference program 132 via network 110. Video conference program 132 allows participants, or users of client computing devices connected via network 110, to interact through live data streaming. Server computing device 130 may include data storage or function as part of the World Wide Web (WWW) and can include spreadsheets, web browser pages or other documents that can be searched for and downloaded to client computing device 120 via network 110 for viewing by a user.

Server computing device 130 may represent a computing system utilizing clustered computers and components to act as a single pool of seamless resources when accessed through a network. This is a common implementation for data centers and for cloud computing applications.
FIG. 2 is a flowchart 200 depicting operational steps of playback program 128 for inserting and playing a video clip into a live video conference, in accordance with an embodiment of the present invention.
Playback program 128 detects a live video conference has been joined, or accessed (block 202). In an exemplary embodiment, conferencing program 126, within which playback program 128 operates, communicates with other participants in the live video conference via video conference program 132 and network 110. In various embodiments of the present invention, a video conference may already be in progress, or may not have started yet.
Playback program 128 determines if camera 124 is turned on (decision block 204). A user can turn on camera 124 and join a video conference through a live feed. If playback program 128 determines that camera 124 is not turned on (the “NO” branch of decision block 204), the program continues to display the live feed of the video conference (block 210). If playback program 128 determines that camera 124 is turned on (the “YES” branch of decision block 204), the program will determine if a user has initiated recording (decision block 206). If playback program 128 determines a recording has not been initiated (the “NO” branch of decision block 206), the program will continue to display the live feed of the video conference (block 210). Otherwise, if playback program 128 determines a user has initiated a recording (the “YES” branch of decision block 206), the program begins recording content, for example, a video clip, using camera 124 (block 208). Next, the program will continue to display the live feed of the video conference (block 210). Thus, in various embodiments of the present invention, playback program 128 can continue to display the live feed of the video conference via UI 122 while recording is taking place.
Playback program 128 may determine a user has initiated a recording by receiving communication via UI 122, such as receiving input a “record” option has been selected. The length of the video clip can be determined by a user. For example, a user may record a video clip of themselves for a pre-determined time, such as 30 seconds, or a user may allow the recording to continue until further action by the user. The content of the video clip may also be determined by the user. For example, a user may record themselves in a particular outfit and with a particular background environment in order to ensure they appear the same during the live video conference and during the recorded content. Playback program 128 can store recorded content temporarily within playback program 128 or in database 129 on client computing device 120.
Subsequently, playback program 128 determines if an indication of an interrupt condition is received (decision block 212). An indication of an interrupt condition is any action or circumstance that indicates the live feed of the video conference is to be interrupted. An indication of an interrupt condition may include such actions as dimming the lights, detecting another person has entered the room or the frame, and receiving a phone call. In an embodiment of the present invention, playback program 128 may include a “play” option, which can be added as an option within conferencing program 126 and displayed on UI 122, and which a user may select to indicate an interruption of the live feed of the video conference. A user may pre-determine within playback program 128 an interrupt condition, or playback program 128 may include default settings. A default setting may be, for example, identifying a disruption in a network connection as an interrupt condition. In an exemplary embodiment of the present invention, an interrupt condition is not necessarily a condition or action that disrupts the live feed of the live video conference, such as a weak network connection, but is instead a user preference, and the user can determine what conditions or actions will interrupt the live video conference and further operation of playback program 128.
In various embodiments of the present invention, an indication of an interrupt condition can include detecting with motion sensors included with camera 124 a change in the user's environment, such as a person entering the room, detecting the user performing a recognized gesture, such as rubbing their eyes or a hand motion, and playback program 128 receiving a key sequence or combination, such as “Ctrl+Alt+L”. In an embodiment of the present invention, playback program 128 can include a “mute/un-mute” option for indicating an interrupt condition. A user may toggle between mute and un-mute according to whether the user wants to play a recorded video, for example, while on mute, or participate in the live video conference, for example, while un-mute is selected. If playback program 128 determines an indication of interrupt is not received (the “NO” branch of decision block 212), the program will continue to display the live feed of the video conference (block 210). Otherwise, if playback program 128 determines that an indication of interrupt is received (the “YES” branch of decision block 212), the program will retrieve selected content (block 214). In various embodiments of the present invention, content can be a video clip or a voice recording. A user of client computing device 120 may select a previously recorded video in temporary storage within playback program 128 or stored in database 129.
Next, playback program 128 plays the selected content in the live video conference (block 216). Playback program 128 inserts the selected content, interrupting the live feed, and plays the content in the live video conference, so that the selected content is displayed to participants in the live video conference. In various embodiments of the present invention, a buffering option may be selected. If a buffering option is selected, playback program 128 prompts a user to select a pre-recorded video clip. Playback program 128 begins buffering the selected pre-recorded video clip. While playback program 128 is running, the buffering option ensures the transition from a live video feed to a recorded clip is smooth, and has no cutout. When the buffering option is selected, playback program 128 plays the length of the video that has been buffered for the user.
Subsequently, playback program 128 determines if an indication to end playback is received (decision block 218). An indication to end playback may include detecting with motion sensors a change in the user's environment, or receiving a key sequence or combination. If an indication to end playback is not received (the “NO” branch of decision block 218), playback program 128 continues to play the selected content. Otherwise, if playback program 128 determines there is an indication to end playback (the “YES” branch of decision block 218), the program ends playback and removes the received content and returns to live feed of the video conference (block 220).
FIG. 3 illustrates an exemplary user interface, such as UI 122 on client computing device 120, in accordance with an embodiment of the present invention.
In an exemplary embodiment of the present invention, a live video conference, displayed on UI 122 of client computing device 120, is shown on video conference display 310 of device 300. Options for operation of playback program 128 are displayed in box 320. Box 320 contains record 322, browse 324, mute option 326, and play 328. Playback program 128 detects whether a camera connected to device 300 is turned on, and if so, a user may select record 322 to begin recording content. In order to determine content to insert into video conference display 310, a user may select browse 324 to browse temporary storage in playback program 128 or storage on client computing device 120, such as database 129. A user may select mute option 326 or play 328 in order to indicate to playback program 128 an interrupt condition. Mute option 326 can allow a user to toggle between playing selected content and the live feed of the video conference, and play 328 can allow a user to play selected content.
