A heater chip has a substrate with one inner and two outer ink vias adjacently arranged. From the output, which includes a modulated signal and a transmitter distortion, the linearizer interacts with the wavelength chirping of the transmitter output. With the oscillation detecting element being inserted into a through hole 2h of a holding member 2 provided in a case 1, the supporting resins 4a, 4b are in close contact with the inner periphery of the through hole 2h. Memory control logic is provided to accommodate a configuration having relatively less random access memory as compared to re-programmable, nonvolatile memory, and to improve access to the re-programmable, nonvolatile memory. In some embodiments, the encoder and decoder define a skipped macroblock as a predicted macroblock whose motion is equal to its causally predicted motion and which has zero residual error. The CODEC device includes a first interface compatible with High Definition Audio specification, a second interface compatible with Musical Instrument Digital Interface specification, and a converter.
