    • A receiver including: a data regeneration mechanism that receives and regenerates data transmitted in units of a packet; a storage device in which received data is stored; a packet ID extraction unit that extracts a packet ID indicating a packet to be re-received; and a retransmission request unit that transmits retransmission request information, which requests retransmission of a packet to be re-received, to a transmitter. The transmitter retransmits only a packet, which is identified with a packet ID specified in the retransmission request information sent from the receiver, to the receiver. The receiver overwrites data, which is stored in the storage device, with data contained in a packet retransmitted from the transmitter. There is thus provided a recovery system for restoring data, which is preserved in the storage device, while regenerating data without stopping a motion picture irrespective of whether a lost packet is present.
    • 一种接收机,包括:数据再生机构,接收并再生以分组为单位发送的数据; 存储接收数据的存储装置; 分组ID提取单元,其提取指示要重新接收的分组的分组ID; 以及重传请求单元,其向发射机发送请求重新发送要重新发送的分组的重传请求信息。 发射机仅将在从接收机发送的重传请求信息中指定的分组ID识别的分组重传到接收机。 接收机将存储在存储装置中的数据用包含在从发射机重发的分组中的数据重写。 因此,提供了一种用于恢复数据的恢复系统,该数据被保存在存储装置中,同时在不停止运动图像的情况下重新生成数据,而不管丢失的分组是否存在。

    • A link tree is able to be formed in a visually logical and natural form for a plurality of objects displayed on a screen. At the time of setting individually selectable links to form an overall object link tree for the plurality of objects displayed on the screen, first processing is carried out for setting a link between an m-th object and an n-th object when only the n-th object exists in a predetermined direction with reference to the m-th object, and second processing is alternatively carried out for setting a link based on a distance of each object existing in said predetermined direction from the m-th object when a plurality of objects exist in a predetermined direction with reference to the m-th object.
    • 链接树能够以视觉上逻辑和自然的形式形成用于显示在屏幕上的多个对象。 在设置单独可选择的链接以形成用于在屏幕上显示的多个对象的整体对象链接树时,执行首先处理以仅在第n个对象和第n个对象之间设置第m个对象和第n个对象之间的链接 相对于第m个物体存在于预定方向上的第二物体,并且当多个物体的第m个物体相对于第m个物体时,可替换地进行第二处理,用于基于从所述第m个物体存在于所述预定方向上的每个物体的距离来设定链接 参照第m个物体在预定方向上存在物体。
