Embodiment Construction
[0059] In order to make the features and advantages of the present invention more obvious and understandable, the specific examples below are described in detail as follows:
[0060] Such as figure 1 As shown, this implementation provides a high-efficiency and low-latency kinesthetic signal codec and codec method, which consists of an encoder and a decoder:
[0061] Among them, the modules of the encoder are divided into signal amplifier, discrete cosine transform (DCT), quantizer, run-length encoding and entropy encoding. The signal passes through each module to generate a code stream such as figure 2 shown.
[0062] The modules of the decoder are divided into entropy decoding, run-length decoding, inverse quantizer, inverse discrete cosine transform (IDCT) and inverse amplifier.
[0063] In this embodiment, three evaluation indicators are used for the codec, which are high efficiency, low delay and perceptually lossless.
[0064] Specifically, such as figure 2 As show...
