Document Type and Number:
WIPO Patent Application WO/2019/090658
Kind Code:
A1
Abstract:
The present application provides a method and device for playing television programs, which can be compatible with television receiving chips of different interfaces. The method is applied to a terminal device; the terminal device comprises 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 main chip and a television receiving chip. The method comprises: the hardware abstraction layer receives a code stream acquisition command sent by a player application of the application layer by means of a first interface, the code stream acquisition command being used for requesting to acquire code streams of a target television program selected by a user; the hardware abstraction layer sends a code stream acquisition instruction to a first driver of the hardware driver layer by means of a second interface, the first driver being a driver of the television receiving chip on the terminal device; the first driver executes the code stream acquisition instruction such that the television receiving chip receives code streams of the target television program; the hardware abstraction layer acquires, by means of the second interface, the code streams of the target television program from the television receiving chip; the hardware abstraction layer sends, by means of the first interface, the code streams of the target television program to a player application; and the player application decodes the code streams of the target television program and plays the decoded audio and video data.
