  1. Which of new digital video recording formats may be regarded as versatile, i.e. the most suitable for all stages of vide program production and giving the best cost-to-performance ratio?
    DVCPRO
    DVCAM
    DV
    Betacam SX
    Digital-S
    None
  2. Which of digital video recording formats are compatible with analogue formats?
    DVCPRO, DVCAM, DV
    Digital-S, DVCPRO, DVCAM
    Digital Betacam, Digital-S, DVCPRO
    Digital Betacam, Digital-S, Betacam SX
    Digital-S, Betacam SX, DVCPRO
  3. Is DVCPRO video recorder suitable for playing back cassettes recorded on machines of other formats?
    No, it can replay DVCPRO cassettes only
    Yes, it can replay DV format cassettes
    Yes, it can replay DV and DVCAM format cassettes
    Yes, it can replay DV and Betacam SP format cassettes
    Yes, it can replay DV, Betacam SP, Digital-S and DVCAM format cassettes
  4. Which compression algorithm is optimal for non-linear edit suite operating with digital video tape recorder?
    Ìotion JPEG
    Without compression
    MPEG2 4:2:2P@ML
    MPEG2 4:2:2P@ML, I-frames only
    The same compression algorithm, as the video recorder uses.
  5. Why parallel-serial switching of sync signal is used in news TV studio complex?
    The switching scheme is simpler
    Because of lower cable consumption
    This could maintain non-interrupted locking signal while hot-swapping of the equipment
    This scheme eliminates cross-channel interference between video, sync and control signals
    There is no reason to do it, serial switching system may be used
  6. How initial material of DVCPRO format can be loaded loss-free to QuickCutter system?
    Through SDI interface
    Through IEEE-1394 interface
    Directly from video cassette by means of built-in video cassette recorder
    With built-in video recorder via CSDI interface at 4-times of nominal transfer rate
  7. Which methods are used for co-ordination of actor and background of virtual reality studio?
    Luminance-keying
    Chroma-keying
    Alpha-channel method
    Chroma-keying for co-ordination with background and Alpha-channel method for co-ordination with foreground
  8. Are there any differences between standard converters and transcoders?
    No, there are different names of the same device
    Yes. Standard converters are used for transfer between TV systems with different frame/line ratio and different color coding standards. Transcoders are used only for transfer between systems with the same frame/line ratio and with different color coding standards
    Yes. Standard converters are used for transfer between TV systems with the same frame/line ratio and different color coding standards. Transcoders are used only for transfer between systems with different frame/line ratio and color coding standards.
    Yes. Standard converters are used for transfer between TV systems with different frame/line ratio and the same color coding standards, and transcoders - vice versa.
