Abstract
A method and apparatus for generating universal splice point adapters, where during a splicing operation an “out-point splicing adapter” is used to transition from an exit stream, while an “in-point splicing adapter” is used to transition to an entry stream.
Claims24
A method for generating a splice point adapter, comprising the steps of:
- identifying at least one out-frame within a transport stream, said out-frame representing a last frame of said transport stream to be included in a spliced transport stream;
- decoding, for each identified out-frame, a respective portion of said transport stream including said out-frame;
- and
- re-encoding each decoded portion of said transport stream to produce a respective out-point adapter, each of said out-point adapters including a predefined terminating out-point condition.

A method for generating a splice point adapter, comprising the steps of:
- identifying at least one in-frame within a transport stream, said in-frame representing a first frame of said transport stream to be included in a spliced transport stream;
- decoding, for each identified in-frame, a respective portion of said transport stream including said in-frame;
- and
- re-encoding each decoded portion of said transport stream to produce a respective in-point adapter, each of said in-point adapters including an predefined initial in-point condition.

In a system for processing transport streams, apparatus for generating a splice point adapter comprising:
- a controller, for identifying at least one out-frame within a transport stream, said out-frame representing a last frame of said transport stream to be included in a spliced transport stream;
- a decoder, responsive to said controller, for decoding each identified out-frame, a respective portion of said transport stream including said out-frame;
- and
- an encoder, for re-encoding each decoded portion of said transport stream to produce a respective out-point adapter, each of said out-point adapters including a predefined terminating out-point condition.
