    • A video recorder for recording a video signal having one frame period and having a high resolution such as a high definition television signal. The video signal in a frame period is divided into two groups for corresponding to a respective field period of the video signal. The two groups are encoded efficiently and independently of each other. After encoding the respective data as respective variable length data signals, pseudo data is added to either one of the variable length data signals having a smaller amount of variable length data than the other variable length data signal so that the amount of variable length data in the divided signals is substantially equal for a designated period. The encoded data is then recorded on an optical disk by a recording mechanism using two respective channels. When reproducing a video signal having lower resolution, such as is used for a standard television system, the video signal is reproduced by decoding the encoded data for one channel. When reproducing video signal having a higher resolution, such as a high definition television signal, the video signal is reproduced by decoding the encoded data from both channels.
    • 一种用于记录具有一个帧周期并且具有高分辨率(诸如高清晰度电视信号)的视频信号的视频记录器。 帧周期中的视频信号被分成两组,用于对应于视频信号的相应场周期。 两组被有效地编码并且彼此独立地编码。 在将各个数据编码为相应的可变长度数据信号之后,将伪数据添加到具有比另一个可变长度数据信号更小的可变长度数据量的可变长度数据信号中的任何一个,使得可变长度数据的量 划分的信号在指定的时间段内基本相等。 然后通过使用两个相应通道的记录机构将编码数据记录在光盘上。 当再现用于标准电视系统的较低分辨率的视频信号时,通过对一个频道的编码数据进行解码来再现视频信号。 当再现具有较高分辨率的视频信号(例如高分辨率电视信号)时,通过对来自两个声道的编码数据进行解码来再现视频信号。

    • In a video signal recording/reproducing apparatus capable of outputting as a reproduced video signal a video signal which has been recorded in advance, a cuttable portion detection section detects a cutting portion in the received video signal while recording a received video signal. A cuttable portion identification section identifies whether or not a reproduced video signal reproduced from a storage device belongs to the cuttable portion detected by the cuttable portion detection section. A switch judgment section receives a result of detection by the cuttable portion detection section and a result of identification by the cuttable portion identification section, and gives an output switch section an instruction to switch a video signal to an output switching section when the switch judgment section judges that the reproduced video signal and the received video signal are contained in the same cuttable portion.
    • 在能够将已经记录的视频信号作为再生视频信号输出的视频信号记录/再现装置中,可剪切部分检测部分在接收到的视频信号的同时检测接收的视频信号中的切割部分。 可切割部分识别部分识别从存储装置再现的再现视频信号是否属于由可切割部分检测部分检测的可切割部分。 开关判断部分通过可切割部分检测部分接收检测结果和可切割部分识别部分的识别结果,并且当切换判断部分切换视频信号到输出切换部分时给出输出切换部分 判定再现的视频信号和接收的视频信号被包含在同一可切割部分中。
