Abstract: A method for decoding a packetized video signal including at least one encoded frame. In one case, the method includes receiving at least one FEC packet at a receiving station. The receiving station uses embedded data associated with the FEC packet to obtain more accurate knowledge of the packet loss state of the media packets. This improved knowledge can allow the receiver to make better use of packet retransmission requests. The embedded data associated with the FEC packet can include in some cases a base sequence number and a packet mask.

Abstract: Provided is a platform for data devices in which the architecture and runtime parameters of the platform are adaptively updated based on real-time data collected about a network on which the platform operates, the source type (e.g., codec selection) for data being communicated between devices, the grouping/architecture of the devices, or any combination thereof. The platform is thus able to support multiple different types and configurations of data devices under varied, constantly-changing conditions. The platform offers a flexible architecture for a content management and rendering system in which multiple data devices connected via the network each play a unique role in the operation of the system. The data devices are capable of dynamically switching between different roles while the system is in active operation. The platform also includes adaptive delay capabilities as well as adaptive codec selection capabilities.

Abstract: A data processing apparatus for detecting a probability of speech based on video data is disclosed. The data processing apparatus may include at least one processor, and a non-transitory computer-readable storage medium including instructions executable by the at least one processor, where execution of the instructions by the at least one processor causes the data processing apparatus to execute a visual speech detector. The visual speech detector may be configured to receive a coordinate-based signal. The coordinate-based signal may represent movement or lack of movement of at least one facial landmark of a person in a video signal. The visual speech detector may be configured to compute a probability of speech of the person based on the coordinate-based signal.

Abstract: A method and system for providing content aware media adaptation are described. Aspects of the invention adaptively down-sample a source video to optimize the encoding process of the source video. The system and method extract content characteristics from the source video by sampling the source video, and then classify the video into one or more content classes based on the extracted characteristics. The content class of the video is used to determine one or more down-sampling settings for the source video. In some aspects, the down-sampling settings are derived by sampling a plurality of videos and determining optimal transitional rates for the plurality of videos. The sampled videos may be used to generate a decision boundary to classify whether a particular video is a good candidate for spatial down-sampling.
