Set-top box browser control focus skip method

Abstract

The embodiment of the invention discloses a set-top box browser control focus skip method, which comprises the following steps of: receiving key message; converting the key message into a standard key event of a browser; shunting the message; searching the last focus by calculating the priorities of all alternative focuses ahead of the current focus to find the focus with highest priority as the last focus; setting the acquired focus with highest priority as the current focus to complete focus skip processing; setting the focus by directly adopting a standard default mode of the browser to complete focus skip processing; searching the next focus by calculating the priorities of all alternative focuses behind the current focus to find the focus with highest priority as the next focus; and setting the acquired focus with highest priority as the current focus to complete focus skip processing. Through the embodiment, accurate skip of upper and lower keys is realized, the browser provides friendly user interaction, and the satisfaction of a user is effectively improved.

Description

Technical field [0001] The invention relates to the field of information technology, in particular to a method for controlling a focus jump of a set-top box browser. Background technique [0002] At present, most set-top boxes, whether digital TV or IPTV; and most mobile phone platforms, are embedded system platforms. Embedded systems have some innate characteristics: 1. The CPU is weak, and the power consumption is low. Most of them are not X86 architectures. Many are based on ARM cores, and some are based on specialized DSP cores. There are many types of CPUs on the PC. 2. Resources such as memory are very limited, generally ranging from 4MB to 64MB. 3. The WEB features that need to be supported do not need to be as rich as the PC version, and generally support the most basic HTML. 4. In addition, the interactive mode of the set-top box is different from that of the PC. The PC uses the keyboard, and the interactive mode of the set-top box is mainly the remote control. [0003...

Problems solved by technology

Embedded systems have some innate characteristics: 1. The CPU is weak in power and low in power consumption. Most of them are not based on X86 architecture, many of them are based on ARM cores, and some are based on special DSP cores. The computing power of these processors is far less than The CPU of the PC, and there are many types

2. Memory and other resources are available very limited, generally ranging from 4MB to 64MB in memory size

This method is very cumbersome to operate and brings a poor experience to users
