Problems solved by technology

The "IPTV set-top box + TV" or digital high-definition TV all-in-one is simple and easy to use, but the IPTV set-top box is essentially an embedded computer or a simplified PC, which is dedicated to the system and lacks flexibility. Generally speaking, since general-purpose PCs have become necessary electrical appliances for many families, purchasing an IPTV set-top box is a repeated investment and increases system operating costs; while general-purpose PCs are convenient, flexible, and have strong general-purpose processing capabilities, but general-purpose PCs are from From the perspective of its design concept and software / hardware system architecture, it mainly meets the needs of offices, and there are still many shortcomings in home entertainment such as IPTV, such as small display screens and poor audio processing effects.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing and example.

[0016] 1. As shown in Figure 1, the home computer and the digital high-definition TV are respectively connected to the corresponding sending end device and receiving end device. The sending end and receiving end devices are identified by the device ID number. Each device has a unique ID number. With 32-bit encoding, it works even with multiple devices and interfering environments. At the same time, the network architecture is a P2P model, a non-traditional C / S model, and supports peer-to-peer point-to-point connections. When a service requester (generally a receiver device) needs a certain service, it first determines the type of service, and then sends a protocol packet to communicate with multiple service providers (generally a sender device) around it to complete the protocol handshake and agreement negotiation process. After the communication is establishe...

Abstract

The method comprises: using wired or wireless approach to connect the PC (personal computer) to the HDTV (high definition TV); the PC executes the IPTV-related client-side software and complete the reception and decode of video stream media signals; the HDTV completes the display of video stream media signals. The invention provides a two-way transmission approach between PC and HDTV, which can either transmits the video (VGA) and audio signals from PC to HDTV, or transmits the controller signals (such as USB, microphone, PS / 2 and computer turn on / turn off control signals)from HDTV to PC.

Description

Technical field [0001] The present invention relates to 3C (Computer, Communicatio and Consumer electronics, ie computer, communication and consumer electronics) fusion and digital home technical field, especially relates to a kind of new IPTV service terminal realization method. Background technique [0002] At present, with the gradual popularization of the INTERNET (Internet) and the continuous improvement of bandwidth, IPTV services and services have received more and more attention from telecom operators and radio and television operators, and have also been loved and used by the majority of users. The IPTV system is also called interactive Internet TV. Its system structure includes streaming media services, program editing, storage, authentication and billing and other subsystems. The main storage and transmission content is streaming media files with MPEG-4 encoding as the core. Computer IP network transmission. [0003] Currently, IPTV user service terminals mainly ...
