Embodiment 1
[0031] figure 2 It shows a flow chart of a code stream transmission method provided by Embodiment 1 of the present invention, which is described in detail as follows:
[0032] In step S201, code stream packets are acquired and descrambled.
[0033] In detail, it can be implemented through the following process:
[0034] receiving the code stream package sent by the server and processed by the first transfer;
[0035] performing descrambling processing on the code stream packet processed through the first transfer;
[0036] The descrambled code stream packets are subjected to a second transfer processing.
[0037] The IPTV CAM terminal obtains the code stream package delivered by the server through the host output; the code stream package is non-transparent and encrypted data sent by the server; the server here refers to the code stream server, and the code stream package can be RTP ( Real-time Transport Protocol: real-time transport protocol) code stream package, which is...
Embodiment 2
[0056] image 3 A schematic structural diagram of a code stream transmission device provided by Embodiment 1 of the present invention is shown.
[0057] The code stream packet obtaining unit 301 is configured to obtain the code stream packet and perform descrambling processing. In detail, the acquisition unit also includes:
[0058] The first transfer module: used to receive the code stream package sent by the host and processed by the first transfer;
[0059] Code stream package descrambling module: used for descrambling the code stream package processed by the first transfer;
[0060] The second capacity-transfer module: used to perform the second capacity-transfer processing on the descrambled stream packets.
[0061] The IPTV CAM terminal obtains the code stream packet delivered to the host, and the code stream packet is sent by the code stream server, which is not transparent data but has been encrypted. In the embodiment of the present invention, the code stream serv...
