Abstract: Methods and apparatus of transmitting haptic data representative of a haptic effect are disclosed. Haptic device data representative of haptic rendering capabilities of a haptic rendering device is obtained. The haptic data is determined by processing received haptic data representative of the haptic effect according to the haptic device data to adapt a rendering of the haptic effect to the haptic rendering capabilities. The haptic data is transmitted to the haptic rendering device.

Abstract: Methods and apparatus of encoding/decoding haptic signal representative of haptic effect. The haptic signal is encoded according to a hierarchical representation, which includes a plurality of layers, a different hierarchical level being associated with each layer. The encoding of the haptic signal comprises the encoding, in the first layer, of a first set of base signals, which includes one or more base signals. First data representative of each base signal of the first set is encoded in this first layer, each base signal being represented in a determined space. Second data is encoded in the first layer in addition to the first data, the second data being representative of modulation of each base signal. Third data representative of the determined space is then encoded in a layer, different from the first layer, having a hierarchical level higher than a hierarchical level of the first layer.
