Occlusionless method for virtual image insertion
A system and method of occlusionless virtual insertion is disclosed that uses an animation of the image. The animation has a full image frame, a null frame, and a number of intervening video frames. When the animation is run, the image appears to be physically moved behind an edge of the animation video frames. An event video-stream is duplicated, and the duplicate delayed to provide a delayed event video-stream. The animation, stopped at the full image frame, is mixed into the delayed event video-stream steam at a selected location using video match moving algorithms. The resultant video-stream is broadcast. The un-delayed, event video-stream is monitored in the region corresponding to where the virtual insertion is occurring in the delayed event video-stream. When this corresponding region begins to become occluded by a foreground object, the animation is triggered. As the time delay of the delayed event video-stream equals the time it takes the animation to run from the full image frame to the null frame, when the foreground object moves into the insertion region in the delayed event video-stream there is no inserted image to occlude it. To the viewer, it appears as if the image is on a movable sign, and just happened to be translated out of view before the object of interest moved into the region. |

Buffer reduction using frame dropping
The techniques described herein may, for example, allow a quantity of buffered video frames to be reduced, for example for use in adaptive bitrate (ABR) streaming and other streaming transmissions. The quantity of buffered video frames may be reduced by dropping certain selected buffered frames from a resulting video output that is displayed to the viewer.

These buffer reduction techniques may sometimes be employed upon a determination that transmission conditions have stabilized and that holding large quantities of buffered video may be unnecessary. In some examples, the disclosed techniques may be particularly advantageous for live streaming scenarios, in which end-to-end latency may be particularly problematic for the viewer. |

Multicasting adaptive bitrate streams
Content providers, such as television companies, may multicast adaptive bitrate content, using playlist-oriented streaming techniques, to recipient devices (such as set-top boxes (“STBs”)). In a playlist-oriented streaming technique, segment files (e.g., segments of the content) may correspond to predetermined time segments. In order to mitigate lag time, when a channel is selected by a user of an STB, which may ordinarily be caused by the nature of playlist-oriented streaming techniques, an STB may obtain content, associated with the selected channel, via a unicast, non-playlist-oriented technique. Once the next segment file has been received by the STB, the STB may cease obtaining the content by the unicast technique, and may use the segment files received via multicast. |

Interactivity driven error correction for audio communication in lossy packet-switched networks
When packet loss is detected during a communication session, a current interactivity mode is checked to determine whether to increase the amount of received audio data stored in a buffer of the receiving device. If the current interactivity mode indicates a low level of interactivity between participants in the communication session, then the total amount of received audio data stored in the buffer is increased, in order to increase the delay between receipt of audio data by the electronic device, and outputting of the audio data by the electronic device. The increased output delay is then used to recover lost packets, so that audio quality is increased while the level of interactivity between participants is low. When the current interactivity mode subsequently indicates higher participant interactivity, the amount of received audio data stored in the buffer may be reduced. |
