Preferred Embodiments of the Present Invention

To explain the objectives, technical scheme and advantages of the present invention, it will now be described in more detail with reference to the attached drawings.

At the current level of technology, the disadvantages of the multiplexing device are in the following aspects:

(1) The operation of the multiplexing device is simplex.

Existing multiplexing devices can only be multiplexers that receive simplex input from an audio / video encoder (or other data services server); or may be remultiplexers receiving a simplex input stream from other multiplexers. Existing multiplexing devices are divided into independent devices that operate independently on the basis of different input streams, which does not allow efficient use of the characteristics of devices of both types (audio / video encoder and multiplexer) with the same output stream for integration, and it is necessary to add a separate multiplexing device for the output of these two types of devices, and as a result, the cost of operation and maintenance increases.

Figure 1 shows a block diagram of a scenario for the joint use of a multiplexer and a remultiplexer used in the existing art for multiplexing an output PMS codestream. 1, the remote multiplexer 101 sends the multiplexed audio / video data to the receiver 103 via satellite 102, while the receiver 103 supplies the PMS code streams to the remux 10; the local multiplexer 106 supplies the PMS code stream to the remultiplexer 107 after multiplexing the local real-time transport protocol (RTP) audio / video stream and the local RTP data stream through the local audio / video encoder 104 and the local data server 105; and a remultiplexer 107 remultiplexes the plurality of input PMS code streams to output a unified PMS code stream. The PMS codestream is transmitted to the wireless receiving terminal 110 by a transmitter 109 after modulation by a modulator 108.

(2) Ease of use is limited due to the use of various multiplexing devices that need to be configured accordingly.

In the application scenario depicted in FIG. 1, two types of multiplexing devices - a multiplexer and a remultiplexer - are able to function normally only by interacting with each other, however, this interaction can be disrupted by many different factors, and therefore, there is an increased risk of receiving an erroneous code or failure.

(3) Existing multiplexers are unable to store the service information in the form of a local file, they are also unable to read the local file to convert it into service information for output by multiplexing, which does not satisfy the requirements of some users regarding the possibility of customization.

For the case where the combined use of multiple multiplexers and remultiplexers is required to output the final frames of multiplexing, if the multiplexing is implemented within the existing standard of Chinese mobile multimedia broadcasting (SMMV), and if there are many types of input code streams, the present invention provides a multiplexing device that performs mixed multiplexing, and the corresponding multiplexing method, and for the case with many types of input codes output streams (e.g., RTP codestream and PMS codestream), first adaptively identify the types of input codestreams and then buffer them according to the mentioned types, then obtain the corresponding multiplexing subframes for various types of codestreams, and these multiplexing subframes are assigned to a given multiplexing frame for multiplexing in accordance with the configuration information of the console with the aim of outputting the PMS code stream that meets the CMSM specification. The present invention also allows you to store the input information of the service in the form of a local file with service information, and also allows you to convert the aforementioned file with service information in a multiplexed PMS code stream for output.

Figure 2 shows the application scenario of a multiplexing device performing mixed multiplexing in accordance with an embodiment of the present invention. 2, a multiplexing device 300 according to the present invention can receive a plurality of input codestream types from a plurality of encoders 201 and a plurality of multiplexers 202, and after adaptively receiving a plurality of input codestream types, output a CMMS standard PMS codestream to a modulator 108 after multiplexing many types of code streams, with the service information being transmitted to the receiving terminal 110 by the receiver 109 after modulation by the modulator 108.

said service control module 702 implements the distribution of services from the service generation module, or stored locally, among the multiplexing frames in accordance with the console configuration and the service control method;

said multiplexing frame forming module 703 implements multiplexing frame generation based on the CMSM standard in accordance with control information provided by the console;

said input / output control module 704 implements input / output control in software and hardware and is capable of forming a virtual adaptive input interface.

FIG. 8 is a flowchart of a mixed multiplexing method in accordance with an embodiment of the present invention. This multiplexing method includes the following steps:

a first step in which the input code streams are adaptively identified and buffered;

if adaptive identification is performed, the characteristic point of the service information and the packet header information can be extracted, while the extracted characteristic point is compared with the characteristic point library of the adaptive identification module of the input stream, and then, after said comparison, they are classified and buffered. The extracted characteristic point of service information can be obtained by extracting packet header information. Said input codestream may be an RTP codestream or a PMS codestream.

The second step, in which the multiplexing subframes of the multiplexing frame are extracted from the buffered code stream in accordance with the type of input code stream, or multiplexing subframes are formed from the input audio / video information;

said multiplexing subframes may be multiplexing subframes conforming to the CMMB multiplexing standard. If this multiplexing device is used in a system with other standards, the multiplexing subframes may also be multiplexing subframes of the respective standards, for example, DVB-H subframes.

A third step is the distribution of services among the multiplexing subframes in accordance with the service control configuration information, wherein the multiplexing subframes are assigned to the corresponding multiplexing frame and buffered to a predetermined buffer;

in the implementation of the above-mentioned distribution associated with the management of services, the generated multiplexing subframes can be assigned to the corresponding multiplexing frame in accordance with the configuration of the console using the N-dimensional table method.

The fourth step is where the multiplexing subframes are obtained from said predetermined buffer and a multiplexing frame is generated in accordance with the multiplexing configuration information, wherein the generated multiplexing frame is converted into a multiplexed code stream for output.

When forming the multiplexing frame, it is necessary to form the multiplexing frame 0 and the header of the multiplexing frame, corresponding to the CMMB multiplexing standard, in accordance with the configuration of the console. At the output, FPGA can be used to split the multiplexing frame and pack it into PMS or IP packets. Said multiplexed codestream is a PMS codestream or an IP codestream.

FIG. 9 is a flowchart of a specific implementation of a mixed multiplexing method in accordance with an embodiment of the present invention.

Step 901, the adaptive input stream identification module receives the service input information, extracts a characteristic point of the service input information and compares said characteristic points with an adaptive comparison library, and also buffers said characteristic points; the adaptive input stream identification module simultaneously receives the PMS stream transmitted by the satellite to the local multiplexer via the remote multiplexer, as well as the RTP data streams of the local audio / video encoder and data server.

Step 902, the service generation module extracts service input information that has successfully passed said comparison to form a subframe;

step 903, the service control module stores the multiplexing subframes received from the service generation unit or from memory (namely, from the storage unit) in a predetermined buffer in accordance with the console information;

step 904, the multiplexing frame-forming module receives the multiplexing subframes from the buffer or from the service control module and generates a multiplexing frame that meets the CMSM multiplexing standard in accordance with the console configuration information;

step 905, the multiplexing subframe generating module (electrically programmable gate array, FPGA) splits the multiplexing frame and packs it into PMS or IP packets, thereby outputting the PMS codestream or IP codestream.

In this case, after step 902, step 906 may also be performed, and the multiplexing subframes are stored in memory as a file with service information; in step 903, services are distributed using the service control module for a file with service information in memory that is stored in a predetermined buffer.

Figure 10 shows another example of a specific application scenario of a multiplexing device performing mixed multiplexing in accordance with an embodiment of the present invention. This multiplexing device 300 can simultaneously receive a PMS stream transmitted from a remote multiplexer 101 via satellite 105 to a local multiplexer, as well as RTP data streams of the local audio / video encoder 104 and data server 105, with the input code stream being adaptively compared with a buffer; and then, the service generation module extracts the input information of the service that has been successfully compared to form the multiplexing subframes in accordance with the background configuration, and then the service management module stores the multiplexing subframes received from the service generation module in a predetermined buffer in accordance with the console configuration information; finally, the multiplexing frame-forming module receives the multiplexing subframes from the buffer, generates the multiplexing subframes corresponding to the CMSM multiplexing standard in accordance with the console configuration information and outputs a PMS stream complying with the CMSB standard.

Since an adaptive service input and control scheme is implemented, the multiplexing device and the multiplexing method of the present invention implement multiplexing of various types of input code streams using a single device, instead of using two types of multiplexers to implement the corresponding input processing of various services. On the one hand, a reduction in the cost of production and maintenance of the station is achieved, and the use of an interface device is also simplified; on the other hand, since a simplex device is used, the risk of receiving an erroneous code or failures, which is present when sharing a plurality of multiplexers, is reduced. In addition, the present invention also provides a service storage scheme convenient for implementing user settings functions. The use of an adaptive scheme also reduces the user's cash costs.

It will be apparent to those skilled in the art that all parts of the steps of the method described above can be implemented by means of a program by issuing instructions to the appropriate hardware, while said programs can be stored on a single computer-readable medium, for example, in read-only memory ( Read-Only Memory, ROM), on a magnetic or optical disk, etc. Optionally, one or more integrated circuits may be used to implement all parts of the steps of the above embodiments of the present invention. Accordingly, each module / unit in the described embodiments of the present invention may take the form of hardware, or a form of software. The present invention is not limited to any particular combination of hardware and software.
