Embodiment Construction

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0027] figure 1 It is a flow chart of the method of TV program switching in an embodiment, such as figure 1 As shown, the TV program switching method includes the following steps:

[0028] S10: When it is detected that the user has operated the remote control to press multiple times in rapid succession, the combination of the Release state of the previous button and the Press state of the next button is converted into a Repeat state.

[0029] When a user needs to change channels to watch a TV program, it will be done through the remote control of the terminal device. If the user presses the key ...

Abstract

The invention relates to a channel changing method and system. According to the channel changing method and system, remote control unit operation behaviors of a user are monitored, when the system detects that the user continuously and rapidly presses keys for multiple times, the Release state of a former key and a Press state of a next key are combined and converted to form a one-time Repeat state, so that only Inforbars of different programs are refreshed, frequency locking is avoided, different PSI / SI (program-specific information / system information) is prevented from being received and analyzed, actual channel changing is not performed, the Release state for actual channel changing is converted into a Repeat state avoiding actual channel changing under the condition of the same channel changing, accordingly, the time occupied by channel changing is greatly reduced, the channel changing speed is greatly increased, channel changing is completed rapidly, and great convenience is brought to the user.

Description

Technical field [0001] The present invention relates to the field of digital television, in particular to a method and system for channel switching of television programs. Background technique [0002] On the receiving terminal equipment (such as set-top boxes, televisions, etc.) in the digital DVB TV system, the main reasons for the slow switching speed and slow switching are caused by the terminal equipment software system and hardware configuration. [0003] In the hardware of the terminal equipment, the reasons that affect the speed of the channel change are relatively simple compared to the software system, and the main reason is that the electrical performance of the electronic components directly affects the working performance of the entire terminal equipment. For example: the electrical performance of the tuner affects its frequency lock speed; the electrical performance of Soc (audio and video decoding performance) affects the switching speed of the entire system and so o...
