Abstract
A terminal device includes an application layer, an operating system layer, a hardware driver layer, and a hardware layer. The operating system layer includes a hardware abstraction layer, and the hardware layer includes a master chip and a television receiver chip. The hardware abstraction layer is disposed between the hardware driver layer and the player application at the application layer, so that the hardware abstraction layer shields the player application from an interface difference of television receiver chips, and provides a unified interface protocol between the player application and the television receiver chip, to be compatible with and support television receiver chips with different interfaces.
