Embodiment 1

[0036] figure 1 It is a flow chart of using CAM to process network data provided by Embodiment 2 of the present invention, combined below figure 1 To specifically describe a method for processing network data using CAM according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0037] S201. Configure a virtual network card for establishing a connection with the host in the CAM.

[0038] Among them, an implementation method of establishing a connection between the virtual network card and the host is, for example:

[0039] (1) CAM dynamically creates a virtual network card device through the Adapter module, and sets routing information to ensure that all data from the client can flow into the virtual network card device;

[0040] (2) The virtual network card driver receives the SYN handshake signal from the Client, the Adapter module calls the LSC resource to obtain the link status between the Host physical link ...

[0069] Figure 5 It is a flow chart of a method for processing network data using CAM provided in Embodiment 3 of the present invention, as shown in Figure 5 As shown, the method for processing network data using CAM provided in this embodiment further includes the following steps on the basis of including the above steps S201, S202, S203 and S204:

[0070] S501. When it is found that the host is disconnected from the target device, close the downlink for communicating with the target device.

[0071] image 3 is a flow chart of communication between a client and a server provided by an example of the present invention, and an implementation scenario according to this embodiment is as follows image 3 As shown, the specific implementation methods are as follows:

[0072] (1) When the Adapter inquires that the connection between the host and the server has been disconnected, the downlink shutdown process is started;

[0073] (2) The Adapter module sends Fin, Ack packets to...

Abstract

The present invention is applicable to the technical field of digital televisions. Provided is a network data distributing and processing method and apparatus based on a Conditional Access Module (CAM). The network data distributing and processing method based on a CAM comprises: configuring, in a CAM, a virtual network card that establishes a connection with a host; obtaining uplink data, and the address and the port information of a target device by means of the virtual network card; transmitting, according to a communication protocol negotiated with the host, the uplink data to the target device in accordance with the address and the port information of the target device; packaging the downlink data obtained by the host in the format of an Ethernet packet, and then writing same to the virtual network card, so that a network client obtains the downlink data from the virtual network card. By means of the present invention, a CAM can accurately parse any data request from a client and transmit valid data to a network operator, so that the CAM obtains an IP network program by means of network access, allowing a user to watch different programs within any period of time, and providing a new experience for the user.

Description

technical field [0001] The invention belongs to the technical field of digital television, in particular to a method and device for processing network data by using a conditional access module. Background technique [0002] The rise of the digital TV era has gradually replaced analog TV, but digital TV is only a change in the signal form for analog TV, and has not touched the transmission mode of media content. With the rapid development of IP networks, more network resources are a good supplement to digital TV programs. For the traditional conditional access module, it mainly integrates the CA module, which can only process DVB programs alone, and gradually cannot meet the needs of ordinary families. As traditional operators transform to a more comprehensive IP network architecture, supporting networked TVs and other devices, IP network products help existing operators deploy a wider range of client devices and commit to opening a wider range of new The business model of ...
