Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a cable television signal transmission method according to an embodiment of the present invention, where the method may be executed by a cable television signal transmission apparatus, where the apparatus may be implemented by software and/or hardware, and the apparatus may be integrated in a first server, that is, an execution subject of the embodiment is the first server in communication connection with a client. Referring to fig. 1, the method of the present embodiment specifically includes:
s110, a first data receiving request which is sent by the client and contains the target parameters is received.
Illustratively, the client may be a set-top box or a digital television all-in-one machine. The developer can request the cable television signal data from the first server through the client for testing or software development of the set top box of the target region.
The target parameter is a parameter corresponding to reception of a cable television signal in a target area, is related to an actual test requirement, and can be a frequency point related to a television program and a corresponding packet identification code (PID) channel value. One frequency point corresponds to a plurality of PID channel values, and each frequency point and the specific PID channel value corresponding to the frequency point can uniquely determine one program.
In the process of performing the cross-regional remote test or software development of the set top box, a developer may request related data from a local server, i.e., the first server in this embodiment, through a client according to actual test requirements. When the client sends the first data receiving request to the local server, the client can send target parameters related to the requested data, such as frequency points, PID channel values and the like, to the local server, so that the local server can send a data request according to the actual test requirement of the client when requesting cable television signal data from the remote server, and the remote server can also obtain the cable television signal data related to the test according to the actual test requirement.
And S120, identifying the data type of the cable television signal corresponding to the target parameter.
Illustratively, the data types of the cable television signal include both streaming media data, which may be understood as television program data, and descriptive data. The descriptive data may be used to describe Specific Information of each tv Program, for example, PSI (Program Specific Information) may be used as the descriptive data to find a Specific Program from a certain TS stream carrying multiple programs, and for example, SI (Service Information) may describe all TS streams.
The target parameter at least includes the packet identification code PID channel value of the cable television signal, and the PID of descriptive data such as PSI, SI and the like is fixedly allocated, so that the data type can be determined by judging whether the PID channel value in the target parameter is matched with the set PID channel value.
Illustratively, if the PID channel value in the target parameter matches the set PID channel value, the data type of the cable television signal corresponding to the PID channel value is determined as descriptive data; and if the PID channel value in the target parameter is not matched with the set PID channel value, determining the data type of the cable television signal corresponding to the PID channel value as streaming media data. Wherein the set PID channel value associated with the target region is available from the digital cable television broadcast system standard (DVB-C).
And S130, if the data type is streaming media data or non-stored descriptive data, sending a second data receiving request based on the target parameters to a second server through communication connection with the second server of the target region.
The target parameter is used for indicating the second server to obtain corresponding target cable television signal data.
For example, if the first server identifies the data type as descriptive data and determines that the descriptive data is stored in the database, the descriptive data may be directly read from the database and forwarded to the client for testing.
Illustratively, if the first server identifies the data type as streaming media data or non-stored descriptive data, a second data reception request based on the target parameter is sent to the second server via a communication connection with the second server in the target area.
The communication connection between the first server and the second server in the target area may be implemented by a VPN (virtual private Network), and there is no development cost on hardware in this communication manner. The second server may be a set-top box for the target site that may obtain local cable television signals based on the target parameters. The target area can be an area where the set top box needs to be tested and set or software development. Because the cable television signal of the target area can only be played locally and cannot be transmitted across areas, the cable television signal transmission across areas can be realized by establishing the communication connection between the first server and the second server, and a data basis is provided for the remote testing of the set top box.
And S140, receiving the target cable television signal data sent by the second server, and forwarding the target cable television signal data to the client for testing.
It should be noted that, after receiving the second data receiving request, the second server may obtain the corresponding target cable television signal data based on the target parameter in the second data receiving request, that is, the target parameter is used to instruct the second server to obtain the corresponding target cable television signal data. The advantage of this arrangement is that the on-demand transmission of the cable television signal is achieved, that is, what data the client wants, and the second server can transmit back the corresponding data for the research and development personnel to test, rather than transmitting all the cable television signal data that can be received to the client. Therefore, in this embodiment, the target cable television signal data acquired by the second server and sent to the first server is data actually needed in a test or research and development process, so that the cable television signal data can be transmitted as required, and the effect of saving bandwidth is achieved.
According to the technical scheme provided by the embodiment of the invention, the first server can identify the data type of the cable television signal corresponding to the target parameter by receiving the first data receiving request which is sent by the client and contains the target parameter. And if the data type is identified to be streaming media data or non-stored descriptive data, sending a second data receiving request based on target parameters to a second server through communication connection with the second server of the target region, wherein the target parameters are used for indicating the second server to acquire corresponding target cable television signal data. And the first server receives the target cable television signal data sent by the second server and forwards the target cable television signal data to the client for testing. By adopting the technical scheme, the remote transmission of the cable television signal is realized, a data base is provided for the test of the cross-region set top box, and the effect of saving bandwidth is achieved.
Example two
Fig. 2 is a flowchart of a cable television signal transmission method according to a second embodiment of the present invention, which is optimized based on the foregoing embodiments, wherein explanations of terms identical to or corresponding to the foregoing embodiments are omitted here for brevity. Referring to fig. 2, the method for transmitting a cable television signal provided in this embodiment specifically includes:
s210, the first server receives a first data receiving request which is sent by the client and contains the target parameters.
The target parameter is a parameter corresponding to the reception of the cable television signal in the target area. The target parameters at least include a packet identifier PID channel value of the cable television signal, and may also include frequency point information of the cable television signal.
For example, after the first server and the second server establish a communication relationship, the client in communication connection with the first server may also search for all frequency points that can be received by the second server through the frequency point search function, and may form a frequency point list. When the client sends the first data receiving request to the first server, the client can sequentially send corresponding data receiving requests according to the frequency point information in the frequency point list, so that all frequency points which can be received by the set top box in the target area can be tested.
S220, the first server judges whether the PID channel value is matched with the set PID channel value, if so, the step S230 is executed; otherwise, step S240 is executed.
S230, the first server determines that the data type of the cable tv signal corresponding to the PID channel value is descriptive data, and continues to execute step S250.
S240, the first server determines that the data type of the cable television signal corresponding to the PID channel value is streaming media data, and continues to execute step S270.
Illustratively, if the data type is streaming media data, the frequency point information is read from the target parameter as a target frequency point of the cable television signal, and a second data receiving request based on the target frequency point and the PID channel value may be sent to the second server.
S250, the first server judges whether the descriptive data are stored in the database or not, if so, the step S260 is executed; otherwise, step S270 is executed.
And S260, the first server extracts the stored descriptive data from the database and forwards the stored descriptive data to the client.
S270, the first server sends a second data receiving request based on the target parameters to the second server through communication connection with the second server of the target area.
Specifically, if the data type is streaming media data, the frequency point information is read from the target parameter as a target frequency point of the cable television signal, and a second data receiving request based on the target frequency point and the PID channel value is sent to the second server. If the data type is descriptive data, reading the PID channel value from the target parameter as a target PID channel value of the cable television signal, and sending a second data receiving request based on the target PID channel value to the second server.
S280, the first server receives the target cable television signal data sent by the second server and forwards the target cable television signal data to the client for testing.
Preferably, the second server receives the cable television signal, and the technical solution of this embodiment is mainly to test the set top box receiving the cable television signal, so that, in order to construct a transmission environment of the cable signal in the test process, that is, to ensure that the client receives the television signal also in the cable format, the first server can restore the target cable television signal data to the cable format signal and then send the cable format signal to the client.
The embodiment is optimized on the basis of the above embodiment, and when the first server sends the target cable television signal data to the client, the first server forwards the target cable television signal data according to the cable format signal, so that the cable format television signal received by the client is ensured, the receiving process of the cable television signal by the second server can be simulated, and an environment for testing the cable television signal received by the client is constructed.
EXAMPLE III
Fig. 3 is a flowchart of a cable television signal transmission method according to a third embodiment of the present invention, where the method may be executed by a cable television signal transmission apparatus, where the apparatus may be implemented by software and/or hardware, and the apparatus may be integrated in a first server of a target area, that is, an execution subject of the embodiment is a second server in communication connection with the first server, and is typically a set-top box for receiving a cable television signal of the target area. Referring to fig. 3, the method of the present embodiment specifically includes:
and S310, receiving a second data receiving request which is sent by the first server and is based on the target parameters through the communication connection with the first server. The target parameters are parameters contained in a first data receiving request which is sent to a first server by a client and aims at the cable television signals of the target area; the second data receiving request is determined to be sent when the first server recognizes that the data type of the cable television signal corresponding to the target parameter is streaming media data or non-stored descriptive data.
The identification method of the first server for the data type of the cable television signal and the interaction process between the first server and the second server may refer to the contents provided in the foregoing embodiments, and details are not described in this embodiment.
And S320, acquiring target cable television signal data corresponding to the target parameters based on the target parameters in the second data request, and sending the target cable television signal data to the first server so that the first server can forward the target cable television signal data to the client for the client to test.
According to the technical scheme provided by the embodiment of the invention, the first server can identify the data type of the cable television signal corresponding to the target parameter by receiving the first data receiving request which is sent by the client and contains the target parameter. And if the data type is identified to be streaming media data or non-stored descriptive data, sending a second data receiving request based on target parameters to a second server through communication connection with the second server of the target region, wherein the target parameters are used for indicating the second server to acquire corresponding target cable television signal data. And the first server receives the target cable television signal data sent by the second server and forwards the target cable television signal data to the client for testing. By adopting the technical scheme, the remote transmission of the cable television signal is realized, a data base is provided for the test of the cross-region set top box, and the effect of saving bandwidth is achieved.
Further, after the first server establishes a communication relationship with the second server, the second server may obtain the descriptive data corresponding to the cable television signal in real time, and send the descriptive data to the first server, so that the first server updates the database corresponding to the descriptive data. If the client sends a data receiving request of the descriptive data to the first server, the first server can firstly inquire whether the descriptive data requested by the client is stored or not from a database corresponding to the descriptive data, and if the descriptive data is stored, the descriptive data can be directly extracted and sent to the client, so that the request of the descriptive data to the second server again can be avoided, and the bandwidth and the time for data transmission are saved.
For example, if it is determined that the database corresponding to the descriptive data does not store the descriptive data requested by the client, the first server still needs to send a second data receiving request about the descriptive data to the second server.
Example four
Fig. 4a is a block diagram of a transmission system of a cable television signal according to a fourth embodiment of the present invention, and as shown in fig. 4a, the transmission system 400 of a cable television signal includes a first server 410 and a second server 420 that are communicatively connected. Wherein the content of the first and second substances,
a first server 410, configured to receive a first data receiving request sent by a client and including a target parameter, where the target parameter is a parameter corresponding to receiving of a cable television signal in a target area; the first server 410 identifies a data type of the cable television signal corresponding to the target parameter, and transmits a second data reception request based on the target parameter to the second server 420 through a communication connection with the second server 420 of the target zone if the data type is streaming media data or non-stored descriptive data.
The second server 420 receives a second data receiving request based on the target parameter sent by the first server 410 through the communication connection with the first server 410, acquires target cable television signal data corresponding to the target parameter based on the target parameter in the second data request, and sends the target cable television signal data to the first server 410, so that the first server 410 forwards the target cable television signal data to the client for the client to test.
Fig. 4b is an interaction diagram of a signal sending server and a signal obtaining server according to a fourth embodiment of the present invention. As shown in fig. 4b, the signal sending server is a first server in this embodiment, and the signal obtaining server is a second server in the target area in this embodiment.
After a client initiates a data receiving request to a signal sending server, the signal sending server judges the data type according to a target parameter in the data receiving request, such as a PID (proportion integration differentiation) channel, if the data is identified to be PSI (program specific information) or SI (service information) data, whether descriptive data exist in a database is continuously judged, and if the descriptive data exist, the descriptive data are forwarded to the client.
If the signal transmission service identifies that the data type is media data or non-stored PSI and SI data, the operations of setting frequency points, setting PID channels, setting filtering parameters and the like can be carried out. The setting has no precedence of the execution sequence, and can be executed simultaneously or sequentially. The purpose of executing the above setting is to determine the frequency point, the PID channel and the filtering parameter corresponding to the data requested by the client, and after the parameters are sent to the signal acquisition server, the signal acquisition server can purposefully acquire and send the wired signal.
Specifically, after the set frequency point, PID channel and filtering parameter are sent to the signal obtaining server, the signal obtaining server can obtain the wired signal according to each parameter sent by the signal sending server, and perform operations such as frequency point filtering, PID channel filtering and parameter filtering on the received wired signal, so as to obtain the filtered data, that is, the data requested to be obtained by the signal sending server, that is, the data required by the research and development staff when performing the remote set-top box test or software development through the client. After receiving the data filtered by the signal acquisition server, the signal transmission server directly forwards the acquired data to the client, so that the research and development personnel can test the set top box in the target area or develop software.
It should be noted that, the signal obtaining server executes the operations of channel filtering, PID channel filtering, parameter filtering, etc., and there is no precedence of the execution sequence, and the operations may be executed simultaneously or successively.
It should be further noted that, after establishing a communication relationship with the signal sending server, the signal obtaining server may obtain PSI and SI channel data from the received wired signal in real time, and if the update of the PSI and SI channel data is found, the updated data may be sent to the PSI and SI database in the signal sending server, so as to implement real-time update of the PSI and SI data blocks.
The embodiment of the invention provides a cable television signal transmission system which comprises a first server and a second server. The first server can identify the data type of the cable television signal corresponding to the target parameter by receiving a first data receiving request which is sent by the client and contains the target parameter. And if the data type is identified to be streaming media data or non-stored descriptive data, sending a second data receiving request based on the target parameters to a second server through a communication connection with the second server of the target region. The second server receives a second data receiving request based on the target parameters and sent by the first server through communication connection with the first server, acquires target cable television signal data corresponding to the target parameters based on the target parameters in the second data request, and sends the target cable television signal data to the first server so that the first server can forward the target cable television signal data to the client for testing by the client. By adopting the technical scheme, the remote transmission of the cable television signal is realized, a data base is provided for the test of the cross-region set top box, and the effect of saving bandwidth is achieved.
