Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The invention provides a technical scheme and system for realizing an interactive terminal platform, mainly including an interactive service basic framework, a VOD service system, an interactive platform system and interfaces of related auxiliary systems. It can easily integrate new business functions and self-expand to meet the increasingly rich proliferating services, and truly realize intelligent interconnection and collaborative services. The interactive platform system is composed of interactive business basic framework and business system. Among them, the basic framework of interactive services consists of a service authentication subsystem, a multi-service portal system (MS Portal) and a set-top box system (CMA). For the VOD ser...

Abstract

The invention discloses a digital TV interaction system which comprises a real-time content addition subsystem and kernel content distribution and management subsystem interface, a BackOffice and multi-service (MS) Portal system interface, a video server subsystem and IPQAM (Internet Protocol Quadrature Amplitude Modulation) subsystem interface, a service certification subsystem and STB (Set Top Box) interface, an MS Portal system and STB interface and a CMA (Configuration Monitor Agent) and STB interface, wherein the service certification subsystem and STB interface is used for enabling an STB to carry out login and authority certification and uses an SOAP (Simple Object Access Protocol); the MS Portal and STB interface is used for providing a bidirectional service browsing and inquiringand value added service entry for the STB and uses an HTTP (Hyper Text Transport Protocol); and the CMA and STB interface is used for providing configuration and state management for the STB and usesan TR069 (Technical Report 069).

Description

technical field [0001] The invention relates to the field of digital television, in particular to a digital television interactive system. Background technique [0002] The domestic and foreign cable TV operators are the first to launch the interactive service VOD service, and Timer Wamer Cable and Comcast in the United States are its representatives. Timer Wamer Cable specifies the On demand Interactive Services Architecture, which is the ISA architecture. The flow control protocol of the ISA architecture adopts the SSP and LSCP protocols based on the ISO / IEC DSM-CC standard, while the front-end server entities are implemented using CORRA, and the implementation complexity is relatively high. The NGOD (Next Generation On Demand) architecture adopted by Comcast is proposed on the basis of the RTSP protocol, and the entity interaction is realized based on WebService. Currently, there are few related commercial products. [0003] Domestic manufacturers basically refer to the...
