Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

Embodiment one

Fig. 1 is a flow chart of a cable TV signal transmission method provided by Embodiment 1 of the present invention, the method can be executed by a cable TV signal transmission device, and the device can be implemented by software and/or hardware, the device It may be integrated in the first server, that is, the execution subject of this embodiment is the first server that has a communication connection with the client. Referring to Fig. 1, the method of the present embodiment specifically includes:

S110. Receive a first data receiving request including a target parameter sent by the client.

Exemplarily, the client may be a set-top box or an all-in-one digital TV. The research and development personnel can request the cable TV signal data from the first server through the client, so as to test the set-top boxes in the target area or conduct software development.

Wherein, the target parameter is a parameter corresponding to the reception of the cable TV signal in the target area, which is related to the actual test requirement, and may be a frequency point related to a TV program and a corresponding packet identification code (PID) channel value. Wherein, one frequency point corresponds to multiple PID channel values, and each frequency point and its corresponding specific PID channel value can uniquely determine a program.

During the cross-regional remote test of the set-top box or the software development process, the R&D personnel can request relevant data from the local server, ie, the first server in this embodiment, through the client according to actual test requirements. Wherein, when the client sends the first data reception request to the local server, it can send target parameters related to the requested data to the local server, such as frequency point and PID channel value, so that the local server requests the cable TV signal from the remote server. data, it can send data requests according to the actual test requirements of the client, so that the remote server can also obtain the cable TV signal data related to the test according to the actual test requirements.

S120. Identify the data type of the cable TV signal corresponding to the target parameter.

Exemplarily, the data types of the cable TV signal include streaming media data and descriptive data, wherein the streaming media data can be understood as TV program data. The descriptive data can be used to describe the specific information of each TV program. For example, PSI (Program Specific Information, program-specific information) as descriptive data can be used to find a specific program from a certain TS stream carrying multiple programs, and then For example, SI (Service Information, service information) can describe all TS streams.

Wherein, because the target parameter at least includes the packet identification code PID channel value of the cable TV signal, and because the PID of descriptive data such as PSI and SI is fixedly allocated, therefore, by judging the PID channel value in the target parameter and setting the PID A match in the channel values determines the data type.

Exemplarily, if the PID channel value in the target parameter matches the set PID channel value, then determine that the data type of the cable TV signal corresponding to the PID channel value is descriptive data; if the PID channel value in the target parameter matches the set PID channel value If the PID channel values do not match, it is determined that the data type of the cable TV signal corresponding to the PID channel value is streaming media data. Wherein, the set PID channel value related to the target area can be obtained from the digital cable broadcasting system standard (DVB-C).

S130. If the data type is streaming media data or unstored descriptive data, send a second data reception request based on the target parameters to the second server through the communication connection with the second server in the target area.

Wherein, the target parameter is used to instruct the second server to acquire corresponding target cable TV signal data.

Exemplarily, if the first server recognizes that the data type is descriptive data and determines that the descriptive data has been stored in the database, it may directly read the descriptive data from the database and forward it to the client, for testing.

Exemplarily, if the first server recognizes that the data type is streaming media data or unstored descriptive data, it sends a second data reception request based on target parameters to the second server through a communication connection with the second server in the target area .

Wherein, the communication connection between the first server and the second server in the target region can be realized through a VPN (Virtual Private Network, virtual private network), and this communication method does not have any hardware research and development costs. The second server may be a set-top box in the target area, and the set-top box may obtain local cable TV signals based on target parameters. Wherein, the target region may be the region where the set-top box needs to be tested and designed or software developed. Since the cable TV signal in the target area can only be played locally and cannot be transmitted across regions, this embodiment can realize the cross-regional transmission of the cable TV signal by establishing a communication connection between the first server and the second server. The off-site test of the set-top box provides the data basis.

S140. Receive the target cable TV signal data sent by the second server, and forward the target cable TV signal data to the client for testing.

It should be noted that after the second server receives the second data receiving request, it can obtain the corresponding target cable TV 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 TV signal data. The advantage of this setting is that it realizes the on-demand transmission of cable TV signals, that is, what data the client wants, the second server can send back the corresponding data for the R&D personnel to test, instead of all the cable TV signals that can be received The data is all transferred to the client. Therefore, in the present embodiment, the target cable TV signal data obtained by the second server and sent to the first server is the data actually needed in the testing or research and development process. The effect of saving bandwidth.

In the technical solution provided by the embodiment of the present invention, the first server can identify the data type of the cable TV signal corresponding to the target parameter by receiving the first data receiving request including the target parameter sent by the client. If it is recognized that the data type is streaming media data or unstored descriptive data, a second data reception request based on target parameters is sent to the second server through a communication connection with the second server in the target area, wherein the target parameters are used for Instruct the second server to acquire the corresponding target cable TV signal data. The first server receives the target cable TV signal data sent by the second server, and forwards the target cable TV signal data to the client for testing. By adopting the above-mentioned technical solution, the remote transmission of the cable TV signal is realized, which not only provides a data basis for the test of the set-top box across regions, but also achieves the effect of saving bandwidth.
