TL;DR: This paper continues with the previous works into a more practical DVC architecture which solves both problems based on the use of machine learning and applies these concepts to pixel-domain Wyner-Ziv coding demonstrating significant savings in bitrates with a little loss of quality.
Abstract: Most of the reported distributed video coding (DVC) architectures have a serious limitation that hinders its practical application. The uses of a feedback channel between the encoder and the decoder require an interactive decoding procedure which is a limitation for applications such as offline processing. On the other hand, the decoder needs an efficient way to estimate the probability of error without assuming the availability of the original video at the decoder. In this paper we continue with our previous works into a more practical DVC architecture which solves both problems based on the use of machine learning. The proposed approach is based on extracting the relationships that exist between the residual frame and the number of requests over this feedback channel. We apply these concepts to pixel-domain Wyner-Ziv coding demonstrating significant savings in bitrates with a little loss of quality.

TL;DR: In this article, the authors describe adaptive video encoding and decoding techniques for encoder-assisted frame rate up-conversion (EA-FRUC), where an encoder selectively encodes at least a portion of a video frame, such as a block, using an interpolated FRUC frame as a reference.
Abstract: This disclosure describes adaptive video encoding and decoding techniques for encoder-assisted frame rate up-conversion (EA-FRUC) An encoder selectively encodes at least a portion of a video frame, such as a block, using an interpolated FRUC frame as a reference The encoder interpolates at least a portion of the FRUC frame at the same time instance as the yet to be encoded video frame, and selects one of a plurality of FRUC encoding modes for that portion, eg, based on rate distortion (RD) The encoder encodes the frame using the selected FRUC encoding mode, the FRUC reference frame, and any additional reference frames that may be indicated A decoder interpolates the FRUC frame and uses it or decoding with knowledge of the particular FRUC mode that was used by the encoder The encoder communicates the FRUC mode for a block via one or more existing parameters in the encoded video frame

TL;DR: In this article, an automatic search for the characteristic elements of a time multiplexing binary frame consisting of a logic circuit equipment which, on receiving such a frame whose parameters are unknown, searches automatically, on the basis of a correlation between the incident signal and the same signal delayed, the number of bits N and makes it possible to determine by simple and rapid manipulations which may be automatic, a synchronization word which exists in principle in any time-multiplexing frame.

TL;DR: In this article, a system and method for adaptive rate control in audio processing is provided, which can include receiving uncompressed audio data from an input and generating MDCT spectrum for each frame using a filterbank.
Abstract: A system and method for adaptive rate control in audio processing is provided. The process could include receiving uncompressed audio data from an input and generating MDCT spectrum for each frame of the uncompressed audio data using a filterbank. The process could also include estimating masking thresholds for current frame to be encoded based on the MDCT spectrum. The masking thresholds reflect a bit budget for the current frame. The process could also include performing quantization of the current frame based on the masking thresholds. After the quantization of the current frame, the bit budget for next frame is updated for estimating the masking thresholds of the next frame. The process could also include encoding the quantized audio data.
