[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] Figure 1 The flowchart of a method for multiplexing a multi-program TS stream provided by an embodiment of the present invention is applicable to the case where a multi-program TS stream is received and then multiplexed. The method can be executed by a multiplexing device for multiplexing a multi-program TS stream. The device can be implemented in the form of hardware and / or software and can be configured in a multiplexing modulator. Figure 1 As shown, the method specifically comprises the following steps:

[0026] S110. When receiving a multi-program TS stream, determine program information of candidate programs corresponding to the multi-program TS stream.

[0027] The multi-program TS stream may be a TS stream including multiple satellite broadcast television programs, for example, multi-program TS stream 1 includes 10 programs, and multi-program TS stream 2 includes 8 programs. The number of multi-program TS streams is more than one, that is, one or more multi-program TS streams can be received at the same time, each of which includes at least one candidate program, and the candidate program may be a program included in each multi-program TS stream.

[0028] Specifically, when a multi-program TS stream is received, the candidate programs and information of the candidate programs included in each multi-program TS stream may be determined.

[0029] In a possible implementation, determining the program information of the candidate programs corresponding to the multi-program TS streams includes: deserializing and decoding the multi-program TS streams through an FPGA to obtain the program information of the candidate programs corresponding to the multi-program TS streams.

[0030] The program information includes all information such as the number of programs, program names and program PID; the number of programs indicates how many different programs are included in the multi-program TS stream; the program name is used to identify and distinguish different programs; and the program PID is a unique identifier for each program.

[0031] Specifically, FPGA is used to process multi-program TS streams, which are usually transmitted in a serial manner. Deserialization can convert the serial data stream into parallel data, and decoding can extract program information related to candidate programs from the TS stream.

[0032] In another possible implementation, after obtaining the program information of the candidate programs corresponding to the multi-program TS streams, the method further includes: sending the program information to a CPU, so as to display the program information on a human-computer interaction interface associated with the CPU based on the CPU.

[0033] In the embodiment of the present invention, the FPGA is used to deserialize and decode the multi-program TS streams, and the program information of the candidate programs is extracted. Through the communication protocol and interface, the program information is sent from the FPGA to the CPU, and then the CPU displays the program information on the human-computer interaction interface, and the user can view and select the program of interest through the interface.

[0034] S120: Receive a selection operation on the program information, and determine a target program associated with the selection operation.

[0035] Specifically, the user browses program information on the human-computer interaction interface and selects a program of interest. The CPU may receive the user's selection operation and analyze the selection operation to determine which program the user has selected, ie, the target program.

[0036] In a possible implementation, receiving a selection operation on the program information and determining a target program associated with the selection operation includes: receiving a selection operation on the human-computer interaction interface and determining a selected target program.

[0037] Wherein, the number of the target programs is more than one. If the number of the target programs is two, the two target programs are matched with at least one of the multi-program TS streams.

[0038] It should also be noted that the user can select some programs or all programs. If the number of target programs is two, the two target programs are matched with at least one multi-program TS stream, which means that the user selects more than two programs, and the more than two programs can correspond to the same multi-program TS stream or different multi-program TS streams.

[0039] S130. Generate configuration parameters according to the target program, and process the multi-program TS streams based on the configuration parameters to obtain a target TS stream corresponding to the target program.

[0040] In the embodiment of the present invention, corresponding configuration parameters can be generated according to the characteristics of the target program, such as program type, encoding format, etc. Then, the multi-program TS streams are processed based on the configuration parameters to extract the TS stream containing the target program, that is, the target TS stream.

[0041] In a possible implementation manner, generating configuration parameters according to the target program includes: generating scrambling source configuration parameters and QAM modulation parameters by the CPU according to the target program.

[0042] The QAM modulation parameters include at least one of frequency, constellation modulation and output level.

[0043] It is understandable that in order to transmit the TS stream to the user, the TS stream usually needs to be encoded and modulated. The appropriate scrambling source and QAM modulation parameters are selected to ensure stable transmission and reception of the signal.

[0044] Specifically, the CPU generates scrambling source configuration parameters and QAM modulation parameters according to the characteristics of the target program. The scrambling source configuration parameters include the specific algorithm or sequence used for scrambling. In the QAM modulation parameters, the frequency point is used to specify the center frequency of the QAM modulated signal, that is, the position of the signal in the spectrum. Constellation modulation is used to describe the distribution of symbols in the complex plane in QAM modulation, that is, the constellation diagram. The output level refers to the level value of the modulated signal output by the modulator, which is used to characterize the power intensity of the modulated signal.

[0045] In a possible implementation, the processing of the multi-program TS stream based on the configuration parameters to obtain the target TS stream corresponding to the target program includes: performing scrambling, RS encoding, convolution interleaving and QAM modulation on the multi-program TS stream through the FPGA according to the scrambling source configuration parameters and QAM modulation parameters to obtain the target TS stream.

[0046] like Figure 2As shown, it is a schematic diagram of the multiplexing modulation principle provided by an embodiment of the present invention. The multiplexing modulator of the present invention includes two parts, one part is FPGA, and the other part is CPU. FPGA is responsible for decoding and encoding of TS stream, and CPU is responsible for sending configuration parameters. The two modules work together to achieve multiplexing management of satellite broadcasting and television programs.

[0047] like Figure 3 As shown, it is an example diagram of multiplexing modulation provided by an embodiment of the present invention.

[0048] Exemplarily, when a TS stream containing 10 programs and a TS stream containing 8 programs are simultaneously connected to the multiplexing modulator, after receiving the TS program stream, the FPGA first deserializes and then decodes. After decoding, the program information in the TS stream, such as the number of programs, program name, program PID, etc., can be obtained. The FPGA sends the decoded program information to the CPU, and the CPU presents it through the human-computer interaction module as a basis for subsequent operations. For example, the subsequent FPGA scrambling code requires the CPU to send the scrambling code source configuration, which is configured through the CPU's human-computer interaction module, such as selecting 8 programs from 10 program streams, selecting 8 programs from 8 program streams, modifying the program PID, etc. After the scrambling code source configuration is sent, the FPGA performs scrambling, RS encoding, convolution interleaving, and combines into a new 16 program streams according to the QAM modulation parameters sent by the CPU, such as frequency, constellation modulation, output level, etc., and sends it to the set-top box, where the set-top box can search and play 16 programs.

[0049] S140: Send the target TS stream to the receiving end.

[0050] Specifically, sending the target TS stream to the receiving end includes: sending the target TS stream to a set-top box.

[0051] The technical solution of the embodiment of the present invention discloses a method for multiplexing multi-program TS streams, the method comprising: upon receiving a multi-program TS stream, determining program information of candidate programs corresponding to the multi-program TS stream, wherein the number of multi-program TS streams is more than one, and each multi-program TS stream includes at least one candidate program; receiving a selection operation on the program information, determining a target program associated with the selection operation; generating configuration parameters according to the target program, and processing the multi-program TS stream based on the configuration parameters to obtain a target TS stream corresponding to the target program and send it to a receiving end. The technical solution of the present invention generates configuration parameters based on the user's selection operation, and then processes the multi-program TS stream based on the configuration parameters to obtain the target program TS stream, which solves the technical problem that the traditional technology directly decodes and plays the multi-program TS stream when it is received, and cannot realize program multiplexing, thereby realizing program multiplexing and obtaining a new program combination.
