Abstract

The invention provides a digital TV receiver and an interactive digital TV system. The existing interactive TV system has the problems such as single application method and incapability of processing operation in quantity. The digital TV receiver of the invention includes a memory, a tuner/demodulator, a decoder, a transmitter and a controller. The digital TV receiver also includes a general interface module controlled by the controller and contains at least a general interface and a processor. An input device is connected with the general interface module through a general interface. After converting the format of input signals uniformly, the processor transmits the input signals to a digital TV operator through an interactive returning channel. By adopting the receiver and the system, a plurality of input devices are connected at the same time; besides, formats of signals of the devices are unified; data transmission method of an uplink is standardized; and guarantee for application and processing with a large quantity of data is given.

Description

technical field [0001] The present invention is related to the digital TV technology, relates to a digital TV receiving device and a digital TV system with a return function, in particular to a digital TV receiving device and an interactive digital TV system capable of accessing various input devices. Background technique [0002] With the birth of digital TV and Internet TV (IPTV), people's viewing mode is no longer the original passive acceptance, but through the platform of interactive TV, it is possible to freely choose programs and participate in program interaction. [0003] However, the existing interactive TV applications are only at a relatively simple level, and users can only participate in programs with poor interactivity and small amount of interactive data, such as TV-on-demand and voting, through the remote control in their hands. For complex interactive services (such as: online games, video chats, etc.), one is the lack of input device interfaces, and device...
