MP3 CD/DVD players: Portable CD players that can decode and play MP3 audio files stored on CDs. Such players were typically a less expensive alternative than either the hard drive or flash-based players when the first units of these were released. The blank CD-R media they use is inexpensive.
The SanDisk SDMX1 series (including the SDMX1-1024, −512, and −256—reflecting capacity in MB), also known as the SanDisk Digital Audio Player, is a low-end solid state memory MP3 player. It was SanDisk's first personal media player, and the only one of its time not to be sold under the Sansa brand.
960H is a resolution used in analog CCTV equipment. 960H represents the number of horizontal pixels in a video signal transmitted from a camera or received by a DVR (Digital Video Recorder). The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels.
Those 74 minutes come from the maximum playtime that the Red Book (audio CD standard) specifies for a digital audio CD (CD-DA); although now, most recordable CDs can hold 80 minutes worth of data. The DVD and Blu-ray discs hold a higher capacity of data, so reading or writing those discs in the same 74-minute time-frame requires a higher data ...
CompactFlash IDE (ATA) emulation speed is usually specified in "x" ratings, e.g. 8x, 20x, 133x. This is the same system used for CD-ROMs and indicates the maximum transfer rate in the form of a multiplier based on the original audio CD data transfer rate, which is 150 kB/s.
More sophisticated conversion schemes (e.g., using deinterlacing to improve the vertical resolution from an NTSC camera) could also be used in higher quality systems. In contrast to the CIF compromise that originated with the H.261 standard, there are two variants of the SIF ( Source Input Format ) that was first defined in the MPEG-1 standard.
(There are two VBR type regions, the main VBR and the backup VBR.) The checksum sector is a checksum of the previous 11 sectors, with the exception of three bytes in the boot sector (flags and percent used). This provides integrity of the VBR by determining whether the VBR was modified.
