Content Management System(PVOD MANAGER)

Description

One of the key components of the whole CAS IPTV architecture is the pre-encryption server. In a VoD scenario, the contents are not encrypted online. Instead they are pre-encrypted, so the VoD system delivers them already encrypted. The system will receive clear contents in a specific directory through an FTP server. For each received content the system will establish a new simulcrypt session with the CAS server. The session will be initialized with a unique access criteria. Once the ECM channel is established, the system will start encrypting all the components included in the service. The encryption algorithm will be CSA, with Cryptoperiod: 10 seconds and CSA type: Packet mode. The system will ask the CAS for a new ECM for each new cryptoperiod generated. This ECM will be inserted in the program stream. Once finished, the result file is loaded in the output directory, with another file containing the license and key information. Earlier, it was supported for TS profile only. Later, we support to MP4 H.264 profile also. We use the marlin encryption to protect the content.

Responsibilities

● Implemented the PreEncryptor(C) and Webutil(PHP) threads.

● Added the free_ca_mode to 1 in SDT and EIT tables after the content was encrypted.

● STB does not show the content as scrambled. Because, PCR data was not encrypted. So, Encrypt the PCR data also.

● CAS Server does not recognise the CW as odd/even.

● Read the PreEncryptor.xml file in C using libXML.

● Establish the channel and stream setup after connection was successfully made with CAS Server.

● Updated CA descriptor with Safeview CA_System ID was added in PMT section.

● Generate log file both in C and PHP.
