摘要： An audio device (e.g. an AV amplifier), with a plurality of audio output terminals according to the HDMI standard, converts audio data of a source device into audio signals suited to audio reproduction abilities (e.g. channel counts) of sink devices. The audio device stores a plurality of audio reproduction ability information describing the predetermined channel count thereof and the channel counts of sink devices, wherein arbitrary audio reproduction ability information precluding audio reproduction ability information of a sink device with the smallest channel count is provided to a source device. The audio device performs down-mixing on audio signals with respect to a sink device whose channel count is smaller than the predetermined channel count, whilst the audio device performs signal processing on audio signals with respect to a sink device whose channel count is larger than the predetermined channel count.

摘要： CLV-type recordable optical disk includes a plurality of tracks which are formed in such a manner that 2&pgr;Tp/&lgr; substantially equals an even-number multiple of 0.5 where Tp is a track pitch and &lgr; is a wavelength of a track wobble. Each of the tracks is divided into a plurality of ECC blocks, and each of the ECC blocks is composed of 16 sectors. Each of the sectors is composed of 26 sync frames. In each of the sectors of the track, information recording areas are set normally in even-numbered sync frames. However, in each portion where there would occur overlap in the information recording area, in the radial direction of the disk, between the track and an adjoining track located inward of the track, the information recording areas are set in odd-numbered sync frames. One piece of address information is divided into a plurality of address information elements and recorded dispersedly in the sync frames across a plurality of the sectors. With such arrangements, the optical disk can minimize adverse influences that would result from cross-talk between wobble signals from the adjoining tracks.
摘要翻译： CLV型可记录光盘包括多个轨道，其以2piTp / lambd基本上等于0.5的偶数倍的方式形成，其中Tp是轨道间距，并且lambd是轨道摆动的波长。每个轨道被分成多个ECC块，并且每个ECC块由16个扇区组成。每个扇区由26个同步帧组成。在轨道的每个扇区中，信息记录区域通常设置在偶数同步帧中。然而，在信息记录区域中，在盘的径向方向上的轨道和位于轨道内侧的相邻轨道之间将发生重叠的每个部分中，信息记录区域被设置为奇数同步帧。一条地址信息被划分为多个地址信息元素，并且分散地记录在多个扇区中的同步帧中。通过这样的布置，光盘可以最小化来自相邻轨道的摆动信号之间的串扰造成的不良影响。
