Embodiment Construction

[0026] 1. Architecture

[0027] The entire set-top box software architecture is as follows figure 2 It can be seen from the figure that the OSD is located at the top layer of the entire set-top box software architecture. Through detailed planning and design, it is responsible for managing and deploying the entire set-top box application program. In this figure, the hardware driver layer provides the definition and operation of the hardware for the system. The operating system MontaVista is the core of the entire set-top box, managing and organizing the software and hardware resources of the entire system. The P2P protocol is the peer-to-peer transmission used for streaming media file transmission Protocol, the player is used to be called by OSD to play video and audio files.

[0028] Specifically, the various levels of the OSD system are divided into image 3 shown in image 3 We can see that the OSD system is divided into six layers. Except for the background layer and th...

Abstract

A realization method for a set-top box in a screen display system based on the peer-to-peer computing technology introduces a graphic layering technology, a bitmap storage technology, an encoding conversion technology, a SOAP technology which are used for meeting the requirements of GUI design, Chinese displaying, XML coding conversion, interaction with an EPG server, etc. that need to be processed in the development of an OSD system. Based on P2P protocol, a solution to the OSD system of an IPTV set-top box is provided on a DM6446 platform to solve the problems of GUI design, Chinese displaying, XML coding conversion, interaction with the EPG server, system integration, etc. Compared with the popular OSD systems for the set-top box in current market, the scheme has the advantages of novelty, flexibility, high expansibility, and high operability.

Description

technical field [0001] The present invention is an implementation scheme of a P2P (Peer-to-Peer) set-top box OSD (On Screen Display) system, mainly used to solve the problem of the latest dual-core development platform TMS320DM6446 (Da Vinci Digital Platform) provided by TI (Texas Instruments) The problem of realizing the graphical user interface operation of P2P set-top box belongs to the application field of peer-to-peer network. Background technique [0002] OSD (On Screen Display) is on-screen display technology, which is widely used in embedded related fields, and is popular because of its highly humanized human-computer interaction interface and good application definition interface. The adoption of OSD technology allows the product to realize complex control functions through simple menu operations, weakening consumers' worries and worries about the use of overly complex functions of the product, and is an indispensable part of the future development of embedded devic...
