Abstract:
1. A method of a signal processor of a random access for a sequence of encoded frames with frames of variable lengths and headers indicating the lengths, comprising: (a) selecting an access point utilizing successive reduction of a complete search space, wherein said access point is not available in meta-data; (b) selecting via the signal processor a sequence of points following said access point; (c) removing points of said sequence which do not have the form of a header, said removing defining a first subset of said sequence of points, wherein said removal eliminates sequential access points; (d) removing points of said first subset which do not jump to other points of said first subset when said points are interpreted as headers, said removing defining a second subset of said first subset; (e) chaining points of said second subset into paths using jumps of said points when interpreted as headers; (f) weighting each of said paths according to the number of other points jumping to points of a path; (g) selecting ones of said paths with a maximum weighting, said selecting defining a third subset of said second subset; and (h) outputting a point from said third subset as a frame header point corresponding to said requested access point wherein said outputted point is within a data stream.
