Abstract

The invention discloses an embedded kernel-based virtual machine (KVM) platform, which consists of hardware, a Linux operating system (OS), JAVACALL, phoneMEFeature and a main control manager, wherein the phoneMEFeature comprises a portable common service library (PCSL), a connected limited device configuration (CLDC) and a mobile information device profile; and the main control manager comprises KVM_Init, KVM_Install, KVM_Run, KVM_Close, KVM_Remove, KVM_Socket, KVM_Download and KVM_Logic. The embedded KVM platform supports a plurality of picture formats, a plurality of Chinese and English input methods and sound mixing, can be used by users conveniently and has the characteristics of low cost, convenience in use and maintenance, convenience in new function development, high user perspective and the like.

Description

technical field [0001] The invention relates to an embedded kilobyte Java virtual machine KVM virtual machine platform. Background technique [0002] For the functional requirements, business applications and technical standards of China Telecom's IPTV set-top box, KVM is one of the necessary items, especially in the value-added service implementation plan of China Telecom, KVM has become its important technical foundation platform. At the same time, in the domestic DVB set-top box market, the broadcasting platform business in some cities and regions has also added KVM-related applications, and KVM is also a must for their needs. The cost of the existing KVM virtual machine is relatively high, resulting in a significant increase in product cost and inconvenience in maintenance and new functions. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art, and provide an embedded kilobyte Java virtual machine KVM vi...
