Embodiment Construction

[0027] The technical solution provided by the present invention is: when the user realizes the channel changing operation through the program plus / minus key, the system first reads the state information of the skip switch of the current channel or the next channel, and judges the state information of the skip switch according to the read state information of the skip switch. Whether the skip switch of the channel is off, if yes, read other information of the channel, control the system to switch to this channel, if not, continue to read the skip switch status information of the channel on / next channel, according to the read Judging whether the skip switch of the channel is off, if yes, read other information of the channel, control the system to switch to the channel, ..., and so on, until the skip switch is found If the channel is off, the control system switches to this channel.

[0028] In order to make the object, technical solution and advantages of the present invention ...

Abstract

The present invention is applicable to the technical field of television, and provides a television receiving device and a channel switching method thereof. The television receiving device includes a control signal receiving module, a skip switch state information memory and an MCU, wherein: the control signal receiving module, used to receive the channel switching instruction, and transmit the instruction to the MCU; the MCU is used to receive the instruction transmitted by the control signal receiving module, analyze the instruction, and switch from the jump switch according to the analysis result The skip switch state information of the up / down channel of the current channel is sequentially read in the state information memory; the skip switch state information memory is used to store the skip switch state information of each channel. The technical solution provided by the invention effectively shortens the channel changing time, improves the channel switching speed, and improves the user experience.

Description

technical field [0001] The invention belongs to the technical field of television, and in particular relates to a television receiving device and a channel switching method thereof. Background technique [0002] In the existing TV system, all the information of a channel, including color system, sound system, channel name, frequency, Liyin mode, automatic frequency tracking switch, skip switch, preference switch, etc., are generally accessed together as a structure. In memory, channel data is read and written based on this structure by channel. In the use of the current TV or set-top box, the most common operation of the user is to change the channel by pressing the program plus / minus key. When changing the channel by pressing the program plus / minus key every time, the usual practice is to read the channel data of the previous / next structure first, and judge whether the skip switch is off, if it is "off", then according to the read The channel data control system is switch...
