Problems solved by technology
Although various input devices are available in various forms and are suitable for different groups of people and scenarios, these input devices are often only designed for the application to which the product belongs and are incompatible with each other.
Even if the input devices use the same transmission method, they cannot be used universally due to the encoding method or private data interface.
[0003] At this stage, IPTV has derived a variety of terminal types, and more and more third-party product applications and services are integrated on IPTV terminals, but these product applications usually have their own independent input devices (remote control, handle, keyboard, etc.) , which causes a terminal to need multiple remote controllers (handles) to support all converged product applications and services, which brings about the problems of high overall cost of IPTV terminals and poor user experience

Embodiment Construction
[0023] The present invention adds an input conversion module to the IPTV terminal, and the input signals of various input devices pass through the receiver and the resource abstraction layer to the input conversion module, and the input conversion module maps the various input signals of all input devices into The corresponding valid key values are forwarded to the target IPTV application. Each target application has an independent input control module, which only processes the preset key value code table. In this way, the purpose of the IPTV terminal being compatible with various input devices is achieved.
[0024] The implementation process of the present invention will be described in detail below in conjunction with the drawings and embodiments.
[0025] figure 1 It is the architecture of the IPTV terminal described in the present invention. The IPTV terminal includes an input signal receiving module, a conversion judgment module, an input conversion module, and an inp...

The invention provides a key value mapping method at a terminal side and an IPTV terminal. The method comprises the following steps: receiving an input signal of an input device; determining whether the input signal needs to be converted or not, if conversion is not needed, sending the input signal to a target application of present IPTV through transparent transmission; if the conversion is needed, determining whether the input device is supported or not, if the input device is not supported, providing an input device candidate list supported by the target application and prompting to reselect an input device, if the input device is supported, searching a corresponding relation between an input signal of the input device in a key value mapping matrix and an input signal identified by the target application; mapping the input signal of the input device to a corresponding input signal identified by the target application, and sending the input signal identified by the target application after mapping to the target application. According to the method and the IPTV terminal of the invention, a user uses the input device and can control all compatible IPTV applications and all integrated product services of the applications.
Description
technical field [0001] The invention belongs to the fields of terminal application and IP application, and provides a compatible support method and terminal for multiple types of remote controllers. Background technique [0002] With the rapid development of remote controls, various types of input devices have emerged, ranging from traditional infrared remote controls to various radio frequency remote controls, such as Bluetooth gamepads. Although various input devices are available in various forms and are suitable for different groups of people and scenarios, these input devices are usually only specially designed for the application to which the product belongs and are incompatible with each other. Even if the input devices adopt the same transmission method, they cannot be used universally due to the encoding method or private data interface. [0003] At this stage, IPTV has derived a variety of terminal types, and more and more third-party product applications and serv...
