ATRAC 데이터는 정수개(8개)의 TS 패킷이 각각의  패킷화된 요소 스트림(PES) 패킷 내에 배치되게 ATRAC 데이터량(159 바이트)이 각각의 TS 패킷 내에 배치되어, PES 패킷으로 전송된다.  결국, ATRAC 데이터의 정수개의 사운드 프레임이 각각의 PES 패킷으로 전송된다.  데이터 전송에서 에러를 검출하기 위해서 첵섬 코드 또한 각각의 TS 패킷 내에 포함된다.

Abstract: 스트랩(strap) 용접 공구 및 그를 위한 방법은 제 1 지지 부재와 밀봉 그립퍼(gripper)의 사이에 배치되는 인장된 스트랩을 맞물리고 유지하기 위해 제 1 지지 부재 쪽으로 밀봉 그립퍼를 이동시키기 위한 제 1 캠 부재, 용접 패드를 진동시키기 위해 진동자 모터를 인에이블시키기 위한 제 2 캠 부재, 및 상기 용접 패드와 상기 제 2 지지 부재의 사이에 배치되는 중첩하는 스트랩 부분을 맞물리고 용접하기 위해 제 2 지지 부재 쪽으로 상기 용접 패드를 이동시키기 위한 제 3 캠 부재를 포함한다. 상기 공구는 작고 불규칙한 적재 하물의 주위에 인장되는 스트랩의 사이로부터 공구의 제거시 스트랩 인장력의 손실을 줄이도록 상대적으로 작은 베이스 플레이트를 포함한다. 진동하는 용접 패드에 의해 맞물리는 스트랩 부분의 칼럼(column) 강도는, 스트랩 부분을 변형시키거나 벤딩시킴에 의해, 바람직하게는 상부 스트랩 부분과 하부 스트랩 부분의 사이에 갭을 형성함에 의해, 감소된다.
