Abstract
A method and a signal processor for receiving a data stream comprising at least two distinct sets of encoded data, at least one set of which is relative to transient/stochastic components of a signal. Based at least in part on the distinct sets of encoded data, the signal processor decodes and reconstructs a corresponding rendition of signal for each set of the encoded data. The distinct sets of renditions of signal are then combined into a single rendition of reconstructed signal.
Claims15
An encoder comprising:
- a denoiser configured to remove noise or transients from an input image signal to output a core image signal;
- a subtractor configured to subtract the core image signal from the input image signal to output a transient image signal;
- a core image signal encoder configured to encode the core image signal independently of the transient image signal to generate encoded core signal data;
- and
- a transient image signal encoder configured to encode the transient image signal at multiple different levels of playback quality to thereby generate a plurality of resulting encoded transient image signals, which are then stored in a repository and which are available for transmission across a network,
- wherein:
- a first encoded transient image signal included among the plurality of resulting encoded transient image signals is selected from the repository and is transmitted across the network, and
- in response to a detected change in a condition of the network, a second encoded transient image signal included among the plurality of resulting encoded transient image signals is selected from the repository and is transmitted across the network in place of the first encoded transient image signal such that the second encoded transient image signal replaces the first encoded transient image signal.

A method of encoding an input video signal, the method comprising:
- removing noise or transients from an input image signal to output a core image signal;
- subtracting the core image signal from the input image signal to output a transient image signal;
- encoding the core image signal independently of the transient image signal to generate encoded core signal data;
- encoding the transient image signal at multiple different levels of playback quality to thereby generate a plurality of resulting encoded transient image signals, which are then stored in a repository and which are available for transmission across a network;
- transmitting a single data stream across the network to a decoder, wherein the single data stream includes the encoded core signal data, and wherein:
- a first encoded transient image signal included among the plurality of resulting encoded transient image signals is selected from the repository and is transmitted across the network with the encoded core signal data in the single data stream, and
- in response to a detected change in a condition of the network, a second encoded transient image signal included among the plurality of resulting encoded transient image signals is selected from the repository and is transmitted across the network in place of the first encoded transient image signal such that the second encoded transient image signal replaces the first encoded transient image signal in the single data stream.
