Abstract: In bitstream recording presentation data is organised into Video Object Units. These have a variable size but have also a variable duration. To allow access to any Video Object Unit in the bitstream a housekeeping address table is used which is based on pieces (VOBU#n) of the bitstream of constant size per piece. The address table additionally contains for each of these pieces a specific delta duration ( DELTA DUR#n) which indicates the arrival time difference between the last and the first packet contained in a piece. The computation of the target VOBU address includes the following steps:   accumulate the delta durations until the given time value is most closely reached towards the target VOBU; the running index of this table entry multiplied by the constant piece size directly results in the address value to be accessed.   <IMAGE>

Abstract: PURPOSE: An environmental-friendly radiation-resistance camera by using a CCD is provided to improve radiation-resistance characteristic of a camera by filling an environmental-friendly radiation shielding agent between a CMOS and an outer housing. CONSTITUTION: An environmental-friendly radiation-resistance camera includes a rotary reflection mirror(6), which is rotated through 360 degrees in order to detect an object. The rotary reflection mirror(6) is rotated by means of a motor. A C-mount zoom lens system(5) is provided to focus an image from light reflected from the rotary reflection mirror(6). A fixing reflection mirror(4) is provided to reflect the image at a right angle. A primary optical lens system(3) is provided to extend the image and a secondary optical lens system(2) is provided to focus the image again. The environmental-friendly radiation-resistance camera also has a CMOS(1), an image processing section(8), an outer housing(10) and a radiation shielding agent(9).
