    摘要： An apparatus and method for controlling recording and reproduction in a video cassette tape recorder are disclosed apparatus is capable of, in a recording mode, separating specific data for speed-varied reproduction from compressed digital video signals, recording them on designated tracks, recording position information of the designated tracks on a control track by an index head or recording position information of recording position-synchronized blocks at the starting portions of the designated tracks recorded with the specific data, and in a speed-varied reproduction mode, controlling a capstan servo speed so as to maintain the travel of a magnetic tape at a normal speed and periodically or non-periodically accelerate or decelerate it where specific data for varied-speed have been recorded periodically or non-periodically on predetermined portions of tracks, thereby making heads travel repeatedly at the normal speed and the high speed and thereby detect continuously the specific tracks for varied-speed. A repeatability of reproduced video at a varied speed is obtained without any deterioration in picture quality, because of recording of the specific data for speed-varied reproduction and the continuous detection of the specific data in the speed-varied reproduction. Apparatus and method for controlling recording and/or reproduction of digital signals to and/or from a digital storage medium, are discussed. According to an embodiment, the method includes receiving digital data, the digital data including video data compressed as at least one of intra-frame and predictive frame, stuffing data, synchronous signals, and relative position information associated with an I-frame; detecting the synchronous signals for decoding the video data; obtaining the video data from the digital data by removing the stuffing data based on stuffing code information; determining a position associated with the I-frame by using the relative position information; determining whether a speed-varied reproduction mode is selected for reproduction of the video data in a varied speed; and reproducing the video data based on the determined position associated with the I-frame, the synchronous signals, and a result of the step of determining whether the speed-varied reproduction mode is selected.

    摘要： Pictures in number indicated by a value (3 in one example) of M in a GOP structure are set as one unit. AUX data (denoted by U in FIG. 32) related to those pictures, audio data (denoted by A in FIG. 32) corresponding to those pictures, and AUX data (denoted by X in FIG. 32) related to the audio data are arranged together at the head of 16 tracks that undergo interleaving. Subsequent to those data, one unit of pictures (3 pictures in one example) is arranged. An HD video signal and an HD audio signal can be recorded and played back with certainty.

    摘要： A technique for reducing the access time in a storage system having serially accessible media. One or more duplicate copies of data are maintained at different offset locations on serial media. When a request is made to read the data, a determination is made as to which copy of the data—either the original data or one of the duplicate copies—will have the shortest access time for accessing the data. Generally, this would be the data copy that will be closest to the data transducer when the tape is positioned for access, such as a tape cartridge being loaded in a tape drive. Once the tape is ready to be accessed, the tape is positioned to access the copy of the data that is in closest linear proximity with the reading transducer. Thus, the copy of the data having the lowest access latency is chosen to satisfy the particular I/O request.

    摘要： A near video-on-demand (VOD) service enabled using a digital video recorder (DVR) for the simultaneous storage and playback of multimedia data. A DVR is connected over a network to a multimedia network source. A VOD selection is requested by the DVR from the network source. A multimedia data signal is received by the DVR from the network source. The data signal contains the requested VOD selection. A first received portion of the received data signal is stored on the DVR. The first received segment is played by the DVR for display on a display device. Simultaneously during the playing of the first received segment, a second received segment of the received data signal is received from the network source and stored on the DVR while the first received segment is played the display device. Thus, the requested VOD selection begins playing on the display device prior to the reception of the entire compressed multimedia data signal so that a requested VOD selection can begin being displayed nearly instantaneously after the request for it is made. A video-on-request (VOR) service is also enabled using a DVR. VOR selection data is received by a centralized database device, such as a network server, from a plurality of users. Each VOR selection data includes at least one requested video selection and video recorder identifying information for identifying each particular video recorder. A transmission priority of requested video selections is determined dependent on the frequency of requests received from the plurality of users. A transmission channel and time is determined based on the transmission priority. DVR control signals are transmitted to automatically tune in the determined transmission channel at the determined transmission time and record the particular video selection.

    摘要翻译： 使用数字录像机（DVR）实现多媒体数据的同时存储和播放的近视频点播（VOD）服务。 DVR通过网络连接到多媒体网络源。 DVR从网络来源请求VOD选择。 多媒体数据信号由DVR从网络源接收。 数据信号包含所请求的VOD选择。 所接收的数据信号的第一接收部分被存储在DVR上。 第一接收段由DVR播放以在显示设备上显示。 在播放第一接收段期间，同时从网络源接收接收数据信号的第二接收段，并且在第一接收段被播放显示设备的同时存储在DVR上。 因此，所请求的VOD选择在接收整个压缩多媒体数据信号之前在显示设备上开始播放，使得在请求的请求之后可以立即开始显示所请求的VOD选择。 还可以使用DVR启用视频点播（VOR）服务。 VOR选择数据由来自多个用户的诸如网络服务器的集中式数据库设备接收。 每个VOR选择数据包括用于识别每个特定视频记录器的至少一个请求的视频选择和视频记录器识别信息。 所请求的视频选择的传输优先级取决于从多个用户接收到的请求的频率来确定。 基于传输优先级确定传输信道和时间。 发送DVR控制信号以在确定的传输时间自动调谐确定的传输信道并记录特定的视频选择。
