Specific implementation mode
The TS method for stream processing and digital multimedia reception device that embodiment provides in order to further illustrate the present invention, under
Face is described in detail in conjunction with Figure of description.
Referring to Fig. 1, TS method for stream processing provided in an embodiment of the present invention includes：
Step S1, signal is received, and original TS is generated according to the signal received and is flowed.
For example, it is illustrated by taking DTV as an example, TV programme are compressed at present, the TS that is packed into circulation
It after normal channel coding and modulation, forms radiofrequency signal and is sent in channel, be transmitted, at this point, in step sl, receiving
Signal be then radiofrequency signal, each vision signal corresponds to TS all the way and flows, per road TS again including at least TV programme all the way in stream
Corresponding single-unit mesh TS streams all have corresponding PID per the corresponding single-unit mesh TS streams of road TV programme, in step sl, according to
When the signal received generates original TS streams, each radiofrequency signal received is handled, it is corresponding to generate original TS streams,
The original TS streams include that at least the corresponding single-unit mesh TS of TV programme flows all the way.
Step S2, according to the PID of the corresponding TS streams of each required multimedia programming, target is extracted from original TS streams
TS flows.
Specifically, after user chooses the multimedia programming needed, then it can learn that required multimedia programming is corresponding
The PID of TS streams extracts each target TS streams according to the PID of the corresponding TS streams of required multimedia programming from original TS streams.
For example, it is assumed that the quantity that user chooses the multimedia programming needed is two, corresponding TS streams are TS-1 and TS-2, TS-
1 and TS-2 is respectively provided with corresponding PID, in step s 2, then according to the PID of the PID of TS-1 and TS-2, from original TS streams
Extract TS-1 and TS-2, wherein TS-1 and TS-2 is likely located in same original TS streams, and TS-1 and TS-2 may also be located at not
In same original TS streams.
Step S3, the packet header for redefining target TS streams forms spare TS streams, and each spare TS streams is merged into all the way
New TS streams, wherein the packet header of each spare TS streams is different.
Specifically, each target TS is flowed after being extracted in original TS streams, it is again fixed to the packet header of each target TS streams
Justice, forms corresponding spare TS streams, and all spare TS streams are then merged into new TS all the way and are flowed.For example, target TS flows
Including two, respectively TS-1 and TS-2 in step sl flow target TS stream TS-1 and target TS streams TS-2 from original TS
In extract after, in step s 2, the packet header of TS-1 is redefined, corresponding spare TS is formed and flows TS-1 ', to TS-2
Packet header redefine, form corresponding spare TS and flow TS-2 ', then by spare TS stream TS-1 ' and spare TS stream TS-2 ' conjunctions
And it is new TS streams all the way.It is noted that when being redefined to the packet header of target TS streams, the rule followed can basis
Actual needs carries out, for example, currently, the packet header of TS streams usually using 0x47 as starting, then, redefine what target TS flowed
Packet header when forming corresponding spare TS stream, then can be waited in packet header that spare TS flows as opening using 0x48,0x49,0x50 ...
Begin, wherein the packet header of each standby stream is different, for example, illustrated so that target TS streams include two as an example, two
Target TS streams are respectively TS-1 and TS-2, and TS-1 ' is flowed in the packet header for redefining target TS streams TS-1 to form corresponding spare TS
When, packet header can be set as to packet header of the spare TS then formed using 0x48 as starting streams TS-1 ' using 0x48 as starting,
When redefining the packet header of target TS streams TS-2 to form corresponding spare TS streams TS-2 ', packet header can be set as with 0x49
As beginning, then packet header of the spare TS that is formed stream TS-2 ' is using 0x49 as starting.It should be noted that in step s3,
When being redefined to the packet header of target TS streams, only the proceeding by for packet header of target TS streams is redefined, and does not change mesh
Mark the PID of the programme content in TS streams.
Step S4, new TS streams are decrypted.
Specifically, in step s 4, standby in being flowed to new TS after all spare TS streams being merged into new TS streams all the way
When programme content in being flowed with TS is decrypted, the packet header of the spare TS streams in can then being flowed according to new TS, in being flowed to new TS
Programme content in spare TS streams is decrypted.For example, it is illustrated so that target TS streams include two as an example, two mesh
It is respectively TS-1 and TS-2 to mark TS streams, in step s3, redefines the packet header of TS-1 and the packet header of TS-2, formation pair respectively
After spare TS stream TS-1 ' and the spare TS streams TS-2 ' answered, the packet header that spare TS flows TS-1 ' is set as using 0x48 as starting,
The packet header of spare TS stream TS-2 ' is set as using 0x49 as starting, in step s 4, when the packet header sought certain spare TS and flowed
It is TS-1 ' using 0x48 as the spare TS streams for when starting, showing to seek, then according to the encryption of the programme content in TS-1 '
The programme content in TS-1 ' is decrypted in mode, when seek packet header of certain spare TS stream using 0x49 as beginning when, table
The bright spare TS streams of this sought are TS-2 ', then according to the cipher mode of the programme content in TS-2 ', to the section in TS-2 '
Mesh content is decrypted.
It should be noted that when the cipher mode of the programme content of each spare TS streams in new TS streams is identical, then show
The mode that the programme content of each spare TS streams in being flowed to new TS is decrypted is also identical, at this point, in step s 4, to new TS
When the programme content in spare TS streams in stream is decrypted, the packet header flowed spare TS can not be sought.
Step S5, the packet header flowed according to spare TS, the spare TS flow points stream during new TS is flowed.
After the decryption of programme content in completing to flow spare TS in step s 4, in step s 5, according to step S3
In packet header that target TS streams are redefined, i.e., the packet header flowed according to spare TS, the spare TS flow points stream during new TS is flowed.It lifts
It for example, is illustrated so that target TS streams include two as an example, two target TS streams are respectively TS-1 and TS-2, in step S3
In, the packet header of TS-1 and the packet header of TS-2 are redefined respectively, flow TS- to form corresponding spare TS stream TS-1 ' and spare TS
When 2 ', packet header of spare TS stream TS-1 ' using 0x48 as starting, packet header of spare TS streams TS-2 ' for using 0x49 as starting,
In step s 4, after being decrypted respectively to the programme content in the programme content and spare TS streams TS-2 ' in spare TS streams TS-1 ',
In step s 5, the new TS streams that TS-1 ' and spare TS stream TS-2 ' merging is formed are flowed to spare TS to shunt, it is standby after shunting
Flowing TS-1 ' and spare TS streams TS-2 ' with TS can need to be transmitted to corresponding unit according to user, for example, when user needs
When spare TS stream TS-1 ' and spare TS streams TS-2 ' is played out, then spare TS stream TS-1 ' and spare TS streams TS-2 ' is passed
Decoder is transported to, can be played out after decoded；When user needs spare TS streams TS-1 ' to play and spare TS stream TS-2 ' records
When processed, then spare TS streams TS-1 ' is transmitted to decoder, is played out after decoded, spare TS flows TS-2 ' then through OTG (On
The Go) interface recorded；It is when user needs spare TS stream TS-1 ' and spare TS streams TS-2 ' to record, then standby
TS-1 ' and spare TS streams TS-2 ' is flowed with TS to be recorded through OTG (On The Go) interface.
As the above analysis, in TS method for stream processing provided in an embodiment of the present invention, according to each institute of user's selection
The PID for needing the corresponding TS streams of multimedia programming, the extraction target TS streams from the original TS streams generated according to the signal received,
Then, the packet header of target TS streams is redefined, forms spare TS streams, keep the packet header of each spare TS streams different, and will be standby
New TS streams all the way are merged into TS streams, then, the programme content in spare TS streams in being flowed to new TS is decrypted, then, root
According to the packet header that spare TS flows, the spare TS streams in being flowed to new TS shunt, so as to the broadcasting or recording of spare TS streams.Cause
Target TS is flowed corresponding spare TS streams and merges into new TS all the way by this in TS method for stream processing provided in an embodiment of the present invention
Stream, the spare TS streams during then TS new to the road flows are decrypted, real by the way that spare TS streams to be incorporated into new TS streams all the way
The decryption of channel TS streams spare to multichannel is now utilized, and then realizes that multichannel target TS flows corresponding multimedia programming
Broadcasting or recording.
In addition, in the prior art, in order to realize that multichannel target TS flows the broadcasting or record of corresponding multimedia programming
System, is usually arranged multiple decryption units such as decryption card, each decryption unit is to mesh all the way in digital multimedia reception device
Mark TS streams are decrypted.And when TS method for stream processing provided in an embodiment of the present invention is applied to digital multimedia reception device,
New TS streams all the way are merged into since each target TS is flowed corresponding spare TS streams, thus it is each in being flowed to the new TS in the road
When spare TS streams are decrypted, only need to a decryption unit be set in digital multimedia reception device and achieve that the road
Each spare TS streams in new TS streams are decrypted, and so as to simplify the structure of digital multimedia reception device, reduce number
The cost of multimedia reception device.
In the above-described embodiments, in step S3, spare TS streams is merged into new TS all the way and are flowed, various ways may be used,
Several merging modes are illustratively enumerated below, but are not limited to following several ways.
Merging mode one, please refers to Fig. 2 and Fig. 3, in step S3, spare TS streams is merged into new TS all the way and are flowed, can be wrapped
It includes：
Step S31, the sum of the transmission rate of each target TS streams is parsed.
Specifically, in step S2, according to the PID of the corresponding TS streams of each required multimedia programming, from original TS streams
Extract target TS stream, then the transmission rate of target TS streams it was determined that the packet header that target TS is flowed redefine to be formed it is spare
After TS streams, spare TS is flowed when merging, first parses the sum of the transmission rate of each target TS stream, due to spare TS streams with it is corresponding
Target TS streams are compared, and only packet header differs, other all sames, thus after the sum of transmission rate for parsing each target TS streams, you can
The sum of the transmission rate for learning each spare TS streams, subsequently to merge the clock of the TS new all the way formed streams to flowing spare TS
Frequency is set.
Step S32, according to the sum of transmission rate of each target TS streams and serial parallel transmission mode, new TS streams are set
Clock frequency.
When spare TS streams are merged into new TS streams all the way, first according to the sum of transmission rate of each target TS streams and string
Parallel transmission mode sets the clock frequency of new TS streams, wherein when using serial transmission mode, the clock frequency of new TS streams
It is numerically identical as the sum of the transmission rate of each target TS streams, when using parallel transmission mode, the clock frequency of new TS streams
It is numerically the sum of the transmission rate of each target TS streams being averaged in parallel line sum, for example, assuming that in step sl
Receive two signals, can generate the original TS of two-way according to two signals flows, the original TS streams of two-way be respectively TS1 and
TS2, wherein referring to Fig. 3, original TS streams TS1 includes two single-unit mesh TS streams, each corresponding matchmakers more all the way of single-unit mesh TS streams
Body segment mesh, two single-unit mesh TS streams are respectively TS1-1 and TS1-2, and the transmission rate of single-unit mesh TS streams TS1-1 is 12Mbps, single
The transmission rate of program TS streams TS1-2 is 28Mbps, then the transmission rate of original TS streams TS1 is 40Mbps, and original TS flows TS2

Clock frequency is 2.75MHz.Correspondingly, when the other a variety of required multimedia programmings of user's selection, the clock frequency of new TS streams
Setting means also use aforesaid way carry out.
It is flowed it should be noted that serial parallel transmission mode includes the serial parallel transmission mode of target TS streams and/or new TS
Serial parallel transmission mode, that is to say, that when setting the clock frequency of new TS streams, need to consider that the serial parallel of target TS streams passes
At least one of the serial parallel transmission mode of defeated mode and new TS streams.
Step S33, spare TS is flowed and is merged, form new TS streams all the way.
After completing to the setting of the new TS clock frequencies flowed, what is formed after the packet header flowed to target TS is redefined is standby
It is flowed and is merged with TS, form new TS streams all the way, the clock frequency of the new TS streams is the clock frequency set in step s 32, this is new
The packet header of spare TS streams is the packet header after being redefined to corresponding target TS streams in TS streams.
In merging mode one, when spare TS streams are merged into new TS streams all the way, first by the transmission rate of each target TS streams
The sum of parse, then according to the sum of transmission rate and serial parallel transmission mode of each target TS streams, set new TS streams
Clock frequency, that is to say, that in merging mode one, transmission rate that the clock frequency of new TS stream is flowed according to each target TS it
With set, can prevent because clock frequency set that new TS flows is too small cause new TS to flow in spare TS streams cannot be timely
It completely transmits, while can prevent from answering the clock frequency set of new TS streams too big and causing in digital multimedia reception device
The wasting of resources.
Merging mode two, please refers to Fig. 4 and Fig. 7, step S3, redefines the packet header of each target TS streams, and packet header is heavy
Each target TS streams after new definition merge into new TS streams all the way, may include：
Step S34, the clock frequency of new TS streams is set, the clock frequency of new TS streams is greater than or equal to each target TS streams
The sum of transmission rate.
Specifically, the clock frequency set new TS flowed is a relatively-stationary value, which is greater than or equal to each target
The sum of the transmission rate of TS streams, wherein the setting means of the clock frequency of new TS streams can there are many.
For example, can according to the new TS streams of the sum of transmission rate of all single-unit mesh TS streams existing at present setting when
Clock frequency, it is assumed that all single-unit mesh TS streams existing at present include that original TS flows TS1-1, TS1-2 in TS1 and original
TS flows TS2-1, TS2-2, TS2-3 in TS2, wherein the transmission rate of single-unit mesh TS streams TS1-1 is 12Mbps, single-unit mesh TS
The transmission rate for flowing TS1-2 is 28Mbps, and the transmission rate of single-unit mesh TS streams TS2-1 is 10Mbps, and single-unit mesh TS flows TS2-2
