    • Apparatus and corresponding methods for storing video information. The apparatus includes a means for receiving video information, a means for converting the received video information into digital video information, and a means for storing the digital video information. Converting the received video information into digital video information can include converting it into an MPEG-compatible digital format. The apparatus can include an MPEG-compatible digital encoder, which can include separate audio and video MPEG encoders. The digital video information can be stored on an electromagnetically writable disk drive with an optimized MPEG file system (OMFS) configured to receive the digital video information and store the digital video information on the disk drive, where the OMFS is configured to divide the received digital video information into one or more packets, each packet having the same number of bytes as a sector on a disk in the disk drive. The OMFS can first accumulate one of the packets of digital video information in a cache memory. The OMFS, upon filling the cache memory with a completed packet of digital video information, then stores the completed packet on a single one of the sectors of the disk drive.
    • 用于存储视频信息的装置和相应方法。 该装置包括用于接收视频信息的装置,用于将接收的视频信息转换为数字视频信息的装置,以及用于存储数字视频信息的装置。 将接收到的视频信息转换为数字视频信息可以包括将其转换成MPEG兼容的数字格式。 该装置可以包括MPEG兼容的数字编码器,其可以包括单独的音频和视频MPEG编码器。 数字视频信息可以存储在具有经配置以接收数字视频信息并且将数字视频信息存储在磁盘驱动器上的优化MPEG文件系统(OMFS)的电磁写入盘驱动器上,其中OMFS被配置为将接收到的数字 视频信息转换成一个或多个分组,每个分组具有与磁盘驱动器中的磁盘上的扇区相同的字节数。 OMFS可以先将数字视频信息的数据包中的一个存储在高速缓冲存储器中。 OMFS在用完整的数字视频信息包填充高速缓冲存储器后,将完成的数据包存储在磁盘驱动器的单个扇区中。
