Abstract: Techniques are disclosed for coding and decoding video data using object recognition and object modeling as a basis of coding and error recovery. A video decoder may decode coded video data received from a channel. The video decoder may perform object recognition on decoded video data obtained therefrom, and, when an object is recognized in the decoded video data, the video decoder may generate a model representing the recognized object. It may store data representing the model locally. The video decoder may communicate the model data to an encoder, which may form a basis of error mitigation and recovery. The video decoder also may monitor deviation patterns in the object model and associated patterns in audio content; if/when video decoding is suspended due to operational errors, the video decoder may generate simulated video data by analyzing audio data received during the suspension period and developing video data from the data model and deviation(s) associated with patterns detected from the audio data.

Abstract: Techniques for encoding and decoding video images based on image content types are described. Techniques include determining a plurality of image content types from metadata or an image content type recognition algorithm, where each image content type corresponding to a portion of a source video, such as a spatial or temporal portion. Encoding parameters, such as quantization parameter, may be selected for portions of source by a constrained search for encoding parameters, where the constraints are based on image content type.

Abstract: The storage method comprises: acquiring a plurality of monitoring dimensionalities associated with each monitoring service and at least one pair of monitoring indicator data including an indicator name and an indicator value; converting the plurality of monitoring dimensionalities into a plurality of row keyword mapping values having the same length, respectively; combining monitoring time with the plurality of row keyword mapping values to form a row keyword, and setting the monitoring time in a fixed time position in the row keyword; and using the row keyword as an index to store a monitoring indicator in a distributed database. A dynamic adjustment of monitoring dimensionalities of data storage for the monitoring system is achieved in accordance with different monitoring services, thereby reducing maintenance costs and improving scalability.

Abstract: A video coder defines multiple fidelity regions in different spatial areas of a video sequence, each of which may have different fidelity characteristics. The coder may code the different representations in a common video sequence. Where prediction data crosses boundaries between the regions, interpolation may be performed to create like kind representations between prediction data and video content being coded.

Abstract: Techniques are disclosed for managing memory allocations when coding video data according to multiple codec configurations. According to these techniques, devices may negotiate parameters of a coding session that include parameters of a plurality of different codec configurations that may be used during the coding session. A device may estimate sizes of decoded picture buffers for each of the negotiated codec configurations and allocate in its memory a portion of memory sized according to a largest size of the estimated decoded picture buffers. Thereafter, the devices may exchange coded video data. The exchange may involve decoding coded data of reference pictures and storing the decoded reference pictures in the allocated memory. During the coding session, the devices may toggle among the different negotiated codec configurations. As they do, reallocations of memory may be avoided.

The striker wheel urges against a flint with its toothed surface of generating sparks. One of the driving caps is normally rotated about the respective driven gear element in a free rotatably movable manner unless a downward force is intentionally applied on the driving cap while rotating the driving cap to drive the respective driven gear element and said striker wheel to rotate for striking against the flint to produce sparks.
