What is the maximum value of Program Clock Reference(PCR) in MPEG?
I understand that it is derived from a 27MHz clock, periodically loaded into a 42bit register.
PCR(i)=PCR_Base(i) * 300 + PCR_Ext(i)
where PCR_Base is loaded into a 33 bits register PCR_Ext is loaded into a 9-bit register.
So, the maximum value of PCR w.r.t 27MHz clock is:
PCR = (2^33 - 1)*300 + (2^9 - 1) = 2,576,980,374,811.
=> (2,576,980,374,811/27,000,000) = 95443.7s = 1590.7 min = 26.5 hours
The register overflow happens after 26.5 hours of continuous streaming. Is this understanding correct?
