Embodiment

The present invention is described in further detail below in conjunction with accompanying drawing:

Referring to Fig. 1, the present invention includes that Program Specific Information PSI and transmission rate are collected, the reconstruct of Program Specific Information PSI and remap, multiplexed three big operating units.At first with in the hard disk or the SPI/ASI by computer receive single-unit order TS stream 1, the single-unit order TS stream 2 that stores in the memory device, single-unit order TS stream n extracts the programme information and the transmission rate of every road program through Program Specific Information PSI and transmission rate collector unit; Generate the programme information of Polymera then in the reconstruct of Program Specific Information PSI and the unit that remaps according to these information, with participate in each multiplexing single-unit order TS flow data again by multiplexed unit multiplexed be one road MPTS TS output.

Fig. 2-11 shows embodiments of the invention.

As shown in Figure 2, the present invention's step that each multiplexing single-unit order specific information PSI and transmission rate are collected is as follows:

[1] seeking public bag identifier in transport stream is for PID number 0 transport stream TS bag, changes the PAT handling procedure over to, extracts the pid information of each Program Map Table PMT correspondence;

[2] the public bag identifier PMT according to appointment in the Program Association Table pat table finds for PID number and the corresponding Program Map Table PMT of this program, change the PMT handling procedure over to, extract the public bag identifier PID of sound, video, obtain the information of Program Map Table pmt table, and obtain video-frequency basic flow, audio frequency in this road program and flow substantially and comprise the pairing public bag identifier PID of Program Clock Reference PCR information, i.e. PCR_PID;

[3] change the transmission rate extraction procedure over to, find each transport stream TS bag that comprises Program Clock Reference PCR, extract the value of Program Clock Reference PCR according to the PCR PID of appointment;

[4] calculate the transmission rate of participating in each multiplexing road transport stream TS according to following transmission rate computing formula with two adjacent PCR:

$\mathrm{transport}\_\mathrm{rate}\left(i\right)=\frac{((i^{\′}-i^{\′\′})\×\mathrm{system}\_\mathrm{clock}\_\mathrm{frequency})}{\mathrm{PCR}\left(i^{\′}\right)-\mathrm{PCR}\left(i^{\′\′}\right)}$

Wherein:

In the i transport stream TS just in the sequence number of decoded byte

Be about to the sequence number of last byte of decoded PCR_base in i ' transport stream TS
