Abstract: PROBLEM TO BE SOLVED: To provide a digital broadcast transmission apparatus which constitutes one broadcast program by switching a plurality of streams of MPEG-2 TS format.SOLUTION: A first correction is performed so that PCR may continue before and after switching. That is, a gap between the PCR and PTS after switching is made to slide as it was, and a correction is performed so that the PCR may continue before and after switching. However, in this correction, the PTS does not always continue. Then, a second correction which secures continuity of the PTS is performed. In addition, a stream after switching is need to be switched from an I frame which is not influenced by a previous frame at the time of carrying out decoding in terms of the property of MPEG-2 TS format stream. Therefore, the PTS of the I frame of the stream after switching is corrected so that the PTS may continue before and after switching.

Title: Pellicle frame, pellicle, and method of manufacturing pellicle frame
Inventor: KITAJIMA SHINTARO
IPC: G03F1/62
Filed: 2010-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a pellicle frame, a pellicle, and a method of manufacturing the pellicle frame such that suppresses breakage of a coating film even when a frame member composed of divided members is coated with a coating material while size precision is secured.SOLUTION: When divided frames of a pellicle frame 2 of a pellicle 1 are coated, the coating material may have a glass transition point of 50 to 150°C. Consequently, even if the pellicle frame 2 flexes, adhesion between the pellicle frame 2 and coating material can be secured and a coating film P is therefore prevented from peeling. Further, the coating film P has predetermined strength, so the coating film P is prevented from being shaven by a handling tool etc. Breakage of the coating film P such as cracking can, therefore, be suppressed. The size can be easily adjusted because of the divided frames, so size precision can be secured.
