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...

Abstract

The invention provides a high-efficiency low-time-delay kinesthetic signal encoder and decoder and a coding and decoding method. The encoder is composed of a signal amplifier, a discrete cosine transform module, a quantizer, a run length encoding module and an entropy encoder; the decoder is composed of an entropy decoder, a run length decoding module, an inverse quantizer, an inverse discrete cosine transform module and an inverse amplifier. Compared with an existing advanced tactile coding method, the high-efficiency low-time-delay kinect signal encoder and decoder design provided by the invention has the advantages that the compression ratio is averagely reduced by 50% in comparison with a tactile coding standard algorithm based on a dead zone, and meanwhile, the distortion degree and the time delay are smaller.

Description

technical field [0001] The invention belongs to the technical field of tactile signal coding, and in particular relates to a high-efficiency and low-delay kinesthetic signal codec and codec method. Background technique [0002] Audio and video are common multimedia interactive content, acting on various physiological senses of human beings. But the scope of multimedia is not limited to hearing and vision. Most users prefer multimedia interactive content that combines audio, video and touch. Because the stimulation of more sensory dimensions, such as touch, can build an immersive experience. In addition, studies have shown that there is a correlation between vision and touch, and that tactile patterns influence auditory and visual media perception. [0003] With the development of multimedia services, tactile signals have gradually become one of the carriers that cannot be ignored by multimedia. Kinesthetic is one of the two main components of tactile signals. Position, ...
