Adjustable from 1 to 60, Full IBP, IP or I only. Open and closed GOP’s are supported. Chroma (Cr and Cb) values are subsampled in both the horizontal and vertical dimensions by a factor of 2. Full D1 Half D1 SIF Color Frequency: 3,579,545 Hz Full D1 Half D1 SIF Color Frequency: 4,433,618.75 Hz Full D1 Half D1 SIF Color Frequency: 3,575,611.49 Hz Full D1 Half D1 SIF Color Frequency: 3,582,056.25 Hz Sampling rates of 44.1 kHz or 48 kHz. Exception: 32 KHz is also supported by the edje Data rates supported for Layer 1 are 32 Kbits/s to 448 Kbits/s in 32 K steps. Data rates supported for Layer 2 are 64, 96, 112, 128, 160, 192, 224, 256, 320, 384 Kbits/s. Free formatted or variable audio bit rates are not compatible.
ADTEC players DO NOT support DVD files made with PCM (Pulse Code Modulation) or Dolby Digital (formerly AC-3) audio. DVD files made with MPEG audio level 2 are qualified. ADTEC Players require video to be captured/recorded in the interlaced scan mode (1,3,5…2,4,6…) aka Field scan. ADTEC players DO NOT support video captured in progressive scan mode (1,2,3,4…). Capture mode cannot be changed during the editing or encoding process. Many DV cameras and PC capture cards/editors capture/record in progressive scan mode. ADTEC players purchased prior to 03/01/02 require the encoded file to be made top field (field 1) first. Some encoders may have a parameter setting which allows change from a bottom field first interlaced scan to a top field first encode. Audio must be MPEG Layer 1 or Layer 2 and multiplexed with Video in either System or Program or Transport stream format. Dolby AC-3 (Dolby Digital), ACC, PCM and WAV audio files are not supported. ADTEC players are designed to play high performance MPEG 2 MP@ML ISO13818 constant or variable bit rate files and decode them to analog NTSC, PAL, PAL-M or PAL-N video formats.
