Method and apparatus for defining entry point in a data stream

A method performed by at least one processor for splitting up a first data stream into a second data stream comprising the start of the first data stream, and a third data stream comprising the end of the first data stream, wherein a first entry point table incorporating a first group of entry points is defined for the first data stream, the method comprising the acts of:

• defining a first entry point table incorporating a first group of entry points;
• the at least one processor selecting a second group of entry points from the first group of entry points, in which the second group of entry points refers to locations in the second data stream;
• forming a second entry point table comprising the second group of entry points;
• selecting a third group of entry points from the first group of entry points, in which the third group of entry points refers to locations in the third data stream;
• forming a third entry point table comprising the third group of entry points;
• determining an interval between the start of the third stream of audiovisual information and a first entry point of the third data stream;
• and
• storing the interval, determined in the previous step, in the third entry point table, wherein the first entry point table defining act includes the acts of:
• generating an entry point table;
• defining a first interval;
• defining entry points in the incoming data stream, in which the entry points are defined at a distance from each other, equal to the first interval by storing entry point addresses giving the location of the defined entry points;
• storing the defined entry points in the entry point table;
• increasing the first interval between the entry points to a second interval in response to the size of the entry point table exceeding a set size;
• and,
• determining new entry points having a mutual distance which is equal to that of the second predetermined interval in response to the size of the entry point table exceeding the set size.

A non-transitory computer readable medium comprising one of an optical storage device, a hard disk, and a memory device, having stored therein computer-readable and executable instructions, wherein the instructions, when executed by a processor enable the computer to perform the acts of:

• defining a first interval;
• defining entry points in the incoming data stream, in which the entry points are defined at a distance from each other, equal to the first interval by storing entry point addresses giving the location of the defined entry points;
• storing the defined entry points in the entry point table;
• increasing the first interval between the entry points to a second interval in response to the size of the entry point table exceeding a set size;
• and,
• determining new entry points having a mutual distance which is equal to that of the second predetermined interval in response to the size of the entry point table exceeding the set size.

An apparatus adapted to define entry points in an incoming data stream, the apparatus comprising:

• a processor;
• and
• a memory for storing information used by the processor;
• wherein the processor is configured to:
• generate an entry point table;
• define a first interval;
• define entry points in the incoming data stream, in which the entry points are defined at a distance from each other, equal to the first interval by storing entry point addresses giving the location of the defined entry points;
• store the defined entry points in the entry point table;
• increase the first interval between the entry points to a second interval in response to a size of the entry point table exceeding a predetermined size;
• and,
• determine new entry points having a mutual distance which is equal to that of the second predetermined interval in response to the size of the entry point table exceeding the predetermined size.
