ABSTRACT:
In bitstream recording presentation data is organized 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 of the bitstream of constant size per piece. The address table additionally contains for each of these pieces a specific delta duration which indicates the time difference between the arrival time of the first packet of a piece and the arrival time of the packet following immediately the last packet of that 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.
