Abstract

The invention relates to an embedded Bluetooth-Ethernet server and provides a new method for watching network TV and requesting a video through a mobile phone and an analog TV set. In the Ethernet server, the internet, an analog TV network and a Bluetooth network are integrated, so that functions of watching the network TV or requesting a network video and the like through a mobile phone terminal and the traditional analog TV set at the same time are realized. The network TV is watched through the mobile phone terminal by adopting a Bluetooth protocol to communicate without paying mobile network using fee. The Bluetooth-Ethernet server adopts an embedded design, integrates external interface equipment, such as an Ethernet interface, a storage, an infrared receiver (AV) and a VGA interface and the like, transplants a Bluetooth protocol stack into an embedded operation system at the same time, and can simultaneously establish connection with the analog TV set and seven mobile phone terminals. The embedded Bluetooth-Ethernet server of the invention can reach a video transmission speed of 15 to 20fps for the analog TV set and the mobile phone terminal under VGA resolution and CIF resolution respectively and guarantee that audio and video are synchronous.

Description

Technical field: [0001] The invention relates to a Bluetooth-Ethernet audio and video processing platform of an embedded system. Background technique: [0002] With the development of communication technology, network technology and embedded system, network video transmission has become possible. At present, more news and other information are released in the form of video. Video sites such as Youku and Tudou are emerging in an endless stream. Live video and on-demand software such as PPLive and SopCast have also become must-have software for network users. With the continuous increase of bandwidth and the development of video coding technology, the video quality and rate are getting higher and higher. However, traditional home users are still accustomed to using TV as an important source of information acquisition and as the first terminal for video viewing. If the host is connected to the display, it will not only bring inconvenience to the user, but also greatly reduce r...
