Case Studies



 Till now, STV has provided services and products to more than 400 operators globally, and issued more than 100 million smart cards. The domestic market share of STV has exceeded 50%, ranking first in China, according to authoritative third-party statistics.

In February, 2002, our company officially signed an agreement with CCTV and became its general integrator of transmission platform construction as well as its vendor of CAS, SMS and EPG systems.
The integration of CCTV digital TV platform was a highly technical project. CCTV adopted CA systems from STV, NDS and Irdeto to do simulcrypt. Due to the differences of conditions between the three CA systems, plus technology blockade from foreign CAS manufacturers and strong coupling between systems, this integration became extremely complex. In order to take full advantages of simulcrypt system, STV created the idea of building an open system, unifying AC (Access Criteria), and independently developed EIS software, which abandoned principal and subordinate CAS deployment methods, and created an open and unified simulcrypt system at business level.
Additionally, CCTV3, CCTV5, CCTV6 and CCTV8 cover more than 7000 regions of China and more than 25 million users. The wide range of aspects and high complexity made this project very rare in the world.
After extensive staff's efforts, STV completed the simulcrypt integration. The three CA systems were running equally, which was first achieved in the world. In April, 2002 the project started design and deployment, and finished In June. CCTV using the system tested the interactive television channel CCTV - SI, during the World Cup. The system has been running successfully since October 1st, 2002.
The design and implementation of this difficult project was entirely crafted by STV. STV overcame various difficulties, successfully completing the task with excellent organization and implementation, gaining high praised from CCTV.
In 2003, CCTV built the first national program platform, according to SARFT’s four major platform project specifications. Relying on strong technical strength and excellent after-sales service ability, STV cooperated again with CCTV on this project, and became its general integrator of transmission platform construction and the vendor of CAS, SMS and EPG system. STV completed simulcrypt integration with NDS, Irdeto and DVN. The system has been running in good condition from October, 2003.
