Operating Software Evolution for Cable Terminals

One way analog terminals No software is required or embedded.

One way vanilla digital terminals light proprietary operating system.

Quasi two way vanilla digital terminals light embedded operating system such as VxWorks,etc.

Quasi two way digital terminals Vxworks or Linux with middleware such MHP and OCAP.

IBB terminalsMostly Linux with middleware

Smart IBB terminals Smart operating system software such as IOS, Android and other smart operating system with significant TV component inside such as RDK or TVOS.

Service Requirements for Smart IBB Terminals

Broadcasting service ( normally one screen )

VOD service

The right smart Operating System solution for Smart IBB Terminals

Based on the service requirement, smart IBB terminals need smart operating software, which currently we have following choices:

Android: Does not support broadcasting services well.

IOS: Closed system, does not support hardware openness． RDK: Smart operating system with significant TV component

inside, support both broadcasting services and other converged media services. Answer from north American cable industry for operating system software of smart IBB terminals.

TVOS: Answer from Chinese cable industry for operating system software of smart IBB terminals.

TV Operating System Software Deployed in The Smart IBB Terminals in SHAOXING City

Conclusion

The trend of media convergence and rapid development of high speed cable broadband is driving the transition of traditional cable terminals to smart ones. This leads to the requirements for TV operating systems.

TV operating system(TVOS) is proposed for smart IBB terminals, with a high security and high converged media processing capability.

This TV operating system(TVOS) has been deployed in the smart IBB terminals in SHAOXING city.
