  1. ; QCIF:

    1. MC

    2. NOMC

    3. NOMC

  2. due to motion vector overhead

    1. inter

    2. intra

    3. inter

  3. For small values in intra mode DC still needs eight bits, while in inter mode it is less.

    number of bits (including the sign bit): 20 + 9 + 5 + 5 + 6 + 6 + 11 + 8 + 8 + 8 + 9 + 7 + 11 + 5 + 8 + 20 + 20 = 166

    no EOB is used, as the last coefficient is coded

  6. @384 kbit/s P = 6 and with q = 62 and P = 6, the buffer content is 36 kbits, left over capacity = 5000 x 8 - 36000 = 4000 bits
