DETAILED DESCRIPTION
FIG. 1 shows an example interactive session system 140 in an example operational context. The interactive session system 140 is an example of a system implemented as one or more appropriately programmed computers in one or more locations, that implement the systems, components, and techniques described below.
A user can interact with the interactive session system 140 using a user device 130 through a data communication network 102. The network 102 enables data communication between multiple electronic devices. Users can access content, provide content, exchange information, and participate in interactive sessions by use of the devices and systems that can communicate with each other over the network 102. The network 102 can include, for example, a local area network (LAN), a cellular phone network, a wide area network (WAN), e.g., the Internet, or a combination of them. The links on the network can be wireline or wireless links or both.
A user device 130 is an electronic device, or collection of devices, that is capable of interacting with the interactive session system 140 over the network 102. Example user devices 130 include personal computers 132, mobile communication devices 134, and other devices that can send and receive data over the network 102. A user device 130 is typically configured with a user application, e.g., a web browser, that sends and receives data over the network 102, generally in response to user actions. The user application can enable a user to display and interact with text, images, videos, music and other content, which can be located on a web page on the World Wide Web or a local area network.
Generally, a user device 130 includes one or more of an audio input device 136-1, a video input device 136-2, a display device 136-3, and optionally other input devices, e.g., for text or gesture input.
The interactive session system 140 allows people using user devices 130 to organize, request, and participate in interactive sessions. In an interactive session, a person interacts with another person, e.g., by viewing a video feed of video being captured by the user device of the other person participating in the session. In some instances, one of the participants can act purely as an observer, i.e., information does not pass from the user device of the observer to the user device of the other person participating in the session. In other instances, however, each person can play an active role, and information goes in both directions during the session. The term “interactive session” may thus refer to such an interaction, the period of interaction, or a recording of such an interaction, as the context requires.
Interactive sessions can be recorded by the interactive session system 140 and stored as session data 142 so that they can be replayed by the users who participated in the sessions or, with the users' consent, by other users. In some implementations, in addition to or instead of being recorded and stored as session data 142, all of or a portion of a video feed provided to a user participating in an interactive session may be recorded and stored locally on the user device of the user.
Generally, during an interactive session, the interactive session system 140 provides live video feeds, live audio feeds, or both captured by user devices for presentation to other users participating in the session. A live feed is a feed that is delivered by the interactive session system 140 in real time. In some circumstances, however, the interactive session system 140 may pause an interactive session while users are participating in the session.
For example, the interactive session system 140 may pause an interactive session if the quality of the interactive session has become unacceptable for one of the participating users. That is, the interactive session system 140 switches the session from a live interaction to an asynchronous interaction, i.e., to an interaction that is delayed as long as necessary to deliver segments of the session to the user with enough fidelity to have an acceptable playback. Pausing an interactive session in response to determining that the quality of the session has become unacceptable is described below with reference to FIG. 2.
As another example, the interactive session system 140 may pause an interactive session to allow one of the users participating in the session to play back a most-recent portion of the session. Pausing an interactive session in response to receiving a request to play back a portion of the session is described in more detail below with reference to FIG. 3.
FIG. 2 is a flow diagram of an example process 200 for pausing an interactive session to ensure acceptable session quality. For convenience, the process 200 will be described as being performed by a system of one or more computers located in one or more locations. For example, an interactive session system, e.g., the interactive session system 140 of FIG. 1, appropriately programmed, can perform the process 200.
The system initiates an interactive session between two users (step 202). That is, for example, the system provides a live video feed and a live audio feed captured by the user device of each user for presentation to the other user.
During the interactive session, the system determines that the quality of the session has become unacceptable for at least one of the users participating in the session (step 204). For example, the system can determine that the video being provided to one of the users has reached a sufficiently low quality, e.g., that the frame rate has dropped below a threshold frame rate value or a video error rate has risen above a threshold error rate. As another example, the system may determine that the user has less than a threshold amount of data communication resources, e.g., bandwidth, available for receiving or providing session-related data from or to the system. As another example, the system may determine that the dropped packet rate or packet timing jitter of packets sent to or received from the user device of the user exceeds a threshold dropped packet rate or a threshold packet timing jitter, respectively.
The threshold values used by the system to determine whether quality is acceptable can vary based on the mode of communication, e.g., audio or video, on the degree of compression of the communication, or on both. Optionally, the system may determine whether the quality has become unacceptable for a user based in part on preferences provided by the user to the system. For example, users of the system may be able to specify a minimum quality that they consider acceptable, e.g., a minimum acceptable video error rate, or a qualitative observation that the system then maps to a quantitative minimum value for a quality measure.
Alternatively, the system can determine that the session quality has become unacceptable based on an input received from the user, e.g., based on receiving an input selecting a designated user interface element from one of the users participating in the interactive session, or based on receiving a voice command input indicating an unacceptable loss of quality.
The system pauses the session (step 206). That is, the session stops providing the live video feeds for presentation to each user. If there is also an audio feed, the system may continue to provide the live audio feed, if quality is acceptable, or pause the audio feed as well.
The system notifies each of the users that the session has been paused (step 208). For example, the system can transmit an audio message to each user indicating that the session has been paused. As another example, the system can provide a text message for display in place of the video feed previously being provided to each user indicating that the session has been paused. The notification can optionally indicate that the session has been paused because the session quality has become unacceptable for one of the users and identify the user. As another example, once the session has been paused, the system can display a single frame of video to the user along with a visual indicator that indicates that the session has been paused. For example, the system can outline the frame in a specified color, cause the border of the frame to flash, and so on. The frame of video that is displayed to each user can be, e.g., the last frame received by that user that has a satisfactory compression ratio. Alternatively, when the indication to pause the session is received, the system can trigger the transmission of a frame of video having a compression ratio that satisfies a specified maximum compression ratio and can then display the transmitted frame.
In some implementations, while the session is paused, the system can, rather than terminating the video feed, trigger the transmission of a low frame rate video feed that captures individual frames that each satisfy a quality threshold.
The system records a session segment, e.g., a segment of audio and video, from one of the users (step 210). In some implementations, the system selects the user that is experiencing low quality to record the initial session segment. In some other implementations, the system selects the other user participating in the session to record the initial session segment. In some other implementations, the system selects the user that was speaking when the indication that quality had become unacceptable was received or when the session was paused to record the initial session segment.
Optionally, prior to recording the segment, the system can prompt the user selected to record a segment to indicate that the recording is going to commence. While the user is recording the segment, the system may provide for display to the user, e.g., a message indicating that the user is being recorded, the last complete frame of video of sufficiently high quality received from the other user, or a count-down timer that counts down the time remaining in the segment. Further optionally, while the user is recording, the system can display an indication to the other user that the user is currently recording a segment.
In some implementations, rather than select a user to record a segment and prompt that user, the system can detect that, after the session has been paused, one of the users has begun speaking and can record a segment from that user. If the system detects that multiple users begin speaking after the session has been paused, the system may, in some implementations, record a segment only from the user that the system detected as speaking first or record a segment from both users. If the system records segments from both users, the system can deliver and present the segment from the user that spoke first with an acceptable quality as described below and then deliver and present the segment from the other user, also with an acceptable quality.
The system can determine how long of a segment to record in any of a variety of ways. For example, the segment can be of a pre-determined duration. As another example, the system may record the segment until receiving a user input indicating that the segment is complete. As yet another example, the system may determine when to stop recording the segment based on tonal inflection or other signals detected in the audio received from the user, e.g., the system may stop recording after detecting a pause that exceeds a threshold length.
The system delivers the segment for presentation to the other user with an acceptable quality (step 212). That is, the system causes the segments to be played back with acceptable quality and at full speed even if play back is delayed due to limited communication resources of the receiving user's user device.
Once the segment has been played back to the other user, the system may then record a segment of video from that user and then provide the segment for presentation to the other user with an acceptable quality. That is, the system may continue the interactive session as a session with pauses rather than as a session that provides live feeds to users, i.e., as a session that ensures that session quality is acceptable by pausing while segments are recorded and then played back to the participating users.
Alternatively, the system may determine that the session may be resumed, i.e., that acceptable session quality has been restored. For example, the system may be able to obtain error rate data from infrastructure and determine whether sufficient session quality has been restored. As another example, the system may be able to establish a different connection with the user's user device and determine that the new connection has a better quality of service guarantee. As yet another example, the system may receive an input from the user specifying that a lower video resolution is acceptable to the user and determine that sufficient bandwidth is available to deliver a live feed of sufficient quality. As another example, the system may, while the session is paused, transmit bursts of test data to the user that is experiencing the unacceptable quality to measure the data communication resources available for the interactive session and restart the session when the available resources exceed a threshold amount.
FIG. 3 is a flow diagram of an example process 300 for pausing an interactive session to play back a portion of the session. For convenience, the process 300 will be described as being performed by a system of one or more computers located in one or more locations. For example, an interactive session system, e.g., the interactive session system 140 of FIG. 1, appropriately programmed, can perform the process 300.
The system initiates an interactive session between two users (step 302). That is, for example, the system provides a live video feed and a live audio feed captured by the user device of each user for presentation to the other user.
During the session, the system receives a replay request from one of the users participating in the session (step 304). For example, the system may detect that one of the users has spoken a predetermined voice command, e.g., “can you repeat that,” “replay,” or “play back,” or a predetermined voice command that was preceded by a predetermined command word. As another example, the system may receive an input submitted by the user by pressing a designated key on an input device or by selecting a designated user interface element.
The session pauses the session (step 306). That is, for example, the session stops providing the live video and audio feeds for presentation to each user.
The system plays back a most-recent portion of the session to the user from whom the replay request was received (step 308). In implementations where the system records the interactive session, the system can provide the most-recent recorded portion of the session for playback to the user. In implementations where the session is recorded by the user's user device, the system can cause the user device to play back the most-recent recorded portion of the session to the user.
The most-recent portion of the session can be, e.g., the portion of the session recorded during a most-recent time window of pre-determined duration. Alternatively, the system can detect a pre-determined most-recent number of verbal pauses or verbal pauses that are classified as meaningful by the system. The system can then identify the earliest of the detected pauses as the beginning of the segment. As another example, a command received from the user can specify a desired length of the most-recent time window, e.g., “please repeat the last ten seconds.” As another example, the system may receive a user input selecting a designated rewind user interface element, e.g., a slider, that allows a user to skip back over previously received video frames, e.g., to skip back a predetermined number of frames or a predetermined number of seconds or to specify the number of frames or seconds, e.g., by dragging the slider.
Optionally, while the portion is being played back to the requesting user, the system can provide a notification to the other user participating in the session that the session is paused. Alternatively, the system can play back the portion to both users.
Once the most-recent portion of the session has been played back to the user, the system resumes the session (step 310). That is, the system resumes providing the live video feeds for presentation to the participating users.
In some implementations, rather than pausing a session in order to replay an earlier portion of the session to a requesting user, the system may allow the user the option of replaying the desired portion without pausing the live video feed. For example, the live video feed may be displayed to the user in one window while the earlier portion of the session is simultaneously displayed in another window. Further, the user may be able to select whether the audio feed corresponding to the live feed or to the earlier portion is to be played. In implementations where the system records the interactive session, the system can provide the requested portion of the session as part of the live feed, e.g., by temporarily transmitting the live feed at a lower quality in order to allow for simultaneous transmission of the recorded portion. In implementations where the session is recorded by the user's user device, the system can cause the user device to play back the requested portion of the session to the user in one window while also displaying the live feed in another window.
