Recording and reproducing apparatus, MPEG image stream recording and reproducing apparatus and medium

Abstract

There is a PSI receipt waiting time of two seconds or so from a start of decoding of an MPEG transport stream to actual display of AV data. There are provided first means of recording 3 for recording a predetermined signal discretely including additional information of a program; means of controlling records 2 for having said predetermined signal recorded by first means of recording 3 ; means of controlling reproduction 4 for having said predetermined signal reproduced from said first means of recording 3 ; means of detecting PSI 1 for detecting program specific information (PSI) from said predetermined signal; and means of adding PSI 5 for adding said PSI to said predetermined signal.

1 . A recording and reproducing apparatus, comprising: 
 recording means for recording an MPEG transport stream including Program Clock Reference (PCR);    detecting means for detecting the PCR from said MPEG transport stream, and    adding means for adding the PCR to the head of the MPEG transport stream upon recording of the MPEG transport stream.    
   
   
       2 . The recording and reproducing apparatus according to  claim 1 , characterized in that said PCR has a cyclic counter value, and a cyclic counter value of PCR added to said MPEG transport stream keeps continuity with a cyclic counter value of PCR included in said MPEG transport stream.  
   
   
       3 . The recording and reproducing apparatus according to  claim 1 , characterized in that said MPEG transport stream to which PCR is added has its contents rewritten.  
   
   
       4 . A recording and reproducing apparatus according to  claim 2 , characterized in that a cyclic counter value of PCR added to said means of adding PCR is rewritten in compliance with a cyclic counter value of PCR originally included in said MPEG transport stream so as to keep said continuity.  
   
   
       5 . A recording and reproducing apparatus, comprising: 
 a recorder for recording an MPEG transport stream including a Program Clock Reference (PCR),    a detector for detecting the PCR from said MPEG transport stream, and    an adder for adding the PCR to the head of the MPEG transport stream upon recording of the MPEG transport stream.    
   
   
       6 . A recording and reproducing method, comprising steps of: 
 recording an MPEG transport stream including a Program Clock Reference (PCR),    detecting the PCR from the MPEG transport stream; and    adding the PCR to the head of the MPEG transport stream upon recording of the MPEG transport stream.    
   
   
       7 . The apparatus of  claim 1  wherein the head of the MPEG transport stream is ahead of the MPEG transport stream.  
   
   
       8 . The apparatus of  claim 5  wherein the head of the MPEG transport stream is ahead of the MPEG transport stream.  
   
   
       9 . The method of  claim 6  wherein the head of the MPEG transport stream is ahead of the MPEG transport stream.
