Service control signal sending and receiving method, device and system

Abstract

The invention discloses a service control signal sending and receiving method, a device and a system; wherein the method comprises the following steps of: monitoring the states of all the keypads of a service control signal sending device; generating a keypad state code identifying the current states of all the keypads; and combining a service type code used for identifying the service types controlled by the service control signal sending device and the keypad state code according to a preset format and generating and sending the service control signals. In the embodiment, the bit number of the keypad state code is identical to the keypad number of the service control signal sending device; and all the bit number value of the keypad state code respectively corresponds to two states of all the keypads, thus leading the keypad state code in one service control signal to show a plurality of keypad states simultaneously and realizing the function of executing a complex operation by combined keypads in electronic games.

Description

technical field [0001] The invention relates to signal processing technology, in particular to a service control signal sending and receiving method, device and system, belonging to the field of electronic technology. Background technique [0002] Internet Protocol Television (Internet Protocol Television, hereinafter referred to as IPTV) is a television broadcasting service based on Internet Protocol (Internet Protocol, hereinafter referred to as IP), and its main features are interactivity and real-time performance. This service uses TV sets or personal computers as display terminals to provide users with various value-added services such as digital broadcasting, video services, information services, interactive communities, interactive leisure and entertainment, and e-commerce through broadband networks, among which the computing power of IPTV set-top boxes is used The business of providing electronic games to users with multimedia processing capabilities is widely welcom...

AI Technical Summary

Problems solved by technology

[0004] 1. Each key corresponds to a key code with a length of 8 bits. If multiple keys are pressed at the same time, only the key code that was pressed first will be sent out. It does not support a complex operation through a combination of keys in video games. function of

[0005] 2. The control signal between the existing remote control and the IPTV set-top box has a total of 32 bits, including application type code, key code, application type code inverse code and key code inverse code, each with 8 bits. When a key is pressed, It takes 80-100 milliseconds to transmit the control signal to the IPTV set-top box, and the response speed is slow, resulting in delays in the operation of video games
