    • By reducing the number of seek operations in an operation to play back a signal from a recording medium, the amount of data temporarily stored in a read buffer memory employed in a signal recording/playback apparatus is large enough to be output as a playback signal during a seek operation, allowing a continuous playback operation to be carried out. In order to reduce the number of seek operations, a signal is always recorded onto the recording medium in continuous free areas each having a size equal to or larger than a predetermined recording/playback time length which is typically set at 1 minute. If it is necessary to insert an additional signal having a length smaller than the predetermined recording/playback time length into a point of insertion in an area already occupied by an existing signal, a continuous free area with a size equal to or larger than the predetermined recording/playback time length is newly allocated to the additional signal. The additional signal is then recorded in the free area instead of being inserted into the point of insertion. Since the free area is larger in size than the length of the additional signal, the rest of the free area is filled up with a portion of the existing signal adjacent to the point of insertion.
    • 通过减少用于从记录介质播放信号的操作中的寻道操作次数,临时存储在信号记录/重放装置中使用的读缓冲存储器中的数据量足够大以作为重放信号被输出 搜索操作,允许执行连续播放操作。 为了减少搜索操作的数量,信号总是被记录在连续空闲区域中的记录介质上,每个区域的大小等于或大于通常设置为1分钟的预定记录/重放时间长度。 如果需要将具有小于预定记录/重放时间长度的长度的附加信号插入到已经被现有信号占据的区域中的插入点中,则具有等于或大于预定记录/重放时间长度的尺寸的连续空闲区域 记录/播放时间长度被新分配给附加信号。 然后将附加信号记录在空闲区域中,而不是插入插入点。 由于空闲区域的尺寸大于附加信号的长度,所以剩余的空闲区域被填充有与插入点相邻的现有信号的一部分。

    • An audio/video synchronizing system and a monitor apparatus can provide a set of contents where the images and the sounds of the contents show lip synchronization to the user so that the user may not have any strange and uneasy feeling if only the images are transmitted wirelessly. A contents server outputs sounds of a set of contents at a timing delayed by an initial delay time (1 second) that is greater than the transmission delay time according to the PTS and the DTS defined by the contents server by taking the largest transmission delay into consideration. The monitor corrects the time base of the STC added to the video packets according to the transmission delay time and subsequently outputs the images according to the SCR, the time base of which is corrected, and the PTS and the DTS, for which the initial delay time is defined. With this arrangement, it is possible to compensate the delay of the transmission delay time and display the images at a timing synchronized with the timing of outputting the sounds. Thus, it is possible to realize lip synchronization between the sounds and the images if only the images are transmitted wirelessly.
    • 音频/视频同步系统和监视器装置可以提供内容的一组内容,其中内容的图像和声音向用户显示唇形同步,使得如果只有图像被无线地发送,用户可能不会有任何奇怪和不安的感觉 。 内容服务器在按照由内容服务器定义的最大传输延迟的PTS和DTS的延迟时间延迟初始延迟时间(1秒)的定时输出一组内容的声音, 考虑。 监视器根据传输延迟时间校正添加到视频分组的STC的时基,并随后根据其时间基准被校正的SCR和PTS和DTS输出图像,其中初始延迟 时间被定义。 利用这种布置,可以在与输出声音的定时同步的定时补偿传输延迟时间的延迟并显示图像。 因此,如果仅有图像被无线地发送,则可以实现声音和图像之间的唇部同步。
