Abstract: Certain examples described herein relate to decoding a video stream within a browser. An encoded multi-layer video stream is received in a source buffer. An encoded base stream is extracted from the source buffer and decoded using a markup video element to obtain a decoded base stream. The decoded base stream is rendered in a first markup video display region, wherein the first markup video display region is hidden. An encoded enhancement stream is extracted from the source buffer and decoded to obtain a decoded enhancement stream. The decoded base stream is obtained from the first markup video display region and combined with the decoded enhancement stream to generate a reconstructed video stream, which is rendered in a second markup video display region that is visible within the browser.

Abstract: The bit rate for encoding a signal is controlled. The signal is encoded using at least two distinct encoding algorithms. An overall bit rate is allocated to at least two components of the signal. A first component of the signal is to be encoded using a first encoding algorithm. A second component of the signal is to be encoded using a second encoding algorithm.

Abstract: A video decoder is provided with: one or more decoder plug-ins that provide a wrapper for one or more respective base decoders to implement a base decoding layer to decode an encoded video signal, each wrapper implementing an interface for data exchange with a corresponding base decoder; an enhancement decoder to implement an enhancement decoding layer, the enhancement decoder being configured to: receive an encoded enhancement signal; and, decode the encoded enhancement signal to obtain one or more layers of residual data, the one or more layers of residual data being generated based on a comparison of data derived from the decoded video signal and data derived from an original input video signal, and a decoder integration layer to control operation of the one or more decoder plug-ins and the enhancement decoder to generate a decoded reconstruction of the original input video signal using and the one or more layers of residual data from the enhancement encoding layer, wherein the decoder integration layer pr

Abstract: A video encoder is provided that has: one or more encoder plug-ins that provide a wrapper for one or more respective base codecs to implement a base encoding layer, each wrapper implementing an interface for data exchange with a corresponding base codec, the base encoding layer being configured to encode and decode a video signal; an enhancement encoder to implement an enhancement encoding layer, the enhancement encoder being configured to: receive a decoded video signal from one of the one or more encoder plug-ins, the decoded video signal comprising a decoded version of an encoded video signal generated by said one of the one or more encoder plug-ins, and generate an encoded enhancement signal for the encoded video signal, the encoded enhancement signal comprising one or more layers of residual data, the residual data being generated based on a comparison of data derived from the decoded video signal and data derived from an input video signal, and, an encoder integration layer to control operation of the o
