Abstract: A video encoder with quality estimation is shown. The video encoder has a video compressor, a video reconstructor, a quality estimator, and an encoder top controller. The video compressor receives the source data of a video to generate compressed data. The video reconstructor is coupled to the video compressor for generation of playback-level data that is buffered for inter prediction by the video compressor, wherein the video reconstructor generates intermediate data and, based on the intermediate data, the video reconstructor generates playback-level data. The quality estimator is coupled to the video reconstructor to receive the intermediate data. Quality estimation is performed based on the intermediate data rather than the playback-level data. Based on the quality estimation result, the encoder top controller adjusts at least one video compression factor in real time.

Abstract: A computer system that processes state messages is described. During operation, the computer system receives, associated with communication network devices in a network, the state messages, where the state messages include different types of state messages having associated priorities. Then, the computer system computes identifiers of the state messages based at least in part on second identifiers of clients associated with or connected to the communication network devices, where, for a given state message, the computer system computes an identifier of the given state message based at least in part on a second identifier of a given client associated with information in the given state message. Next, the computer system may selectively assign the state messages to dedicated message queues having associated processing priorities based at least in part on the computed second identifiers and/or the types of state messages.
