Description

201215050 VI. Description of the Invention: [Technical Field] The present invention relates to an open service gateway capable of processing and transmitting a body stream, and a method for processing and transmitting a multimedia jet, in particular Transcoding television signal and universal plug-and-play multimedia device file stream into multi-media jet, and transmitting the multimedia stream to an open user gateway of a remote user and processing and transmitting multimedia stream . [Prior Art] With the rapid development of digital technology, it is a future trend to use smart communication technology to build a smart living space to enhance the service function of life. In particular, the market potential of digital homes is huge, and many sfL and tantalum manufacturers have successively Investing in product development and technical standards. However, the heterogeneous product interface makes the application of each manufacturer's products subject to brown limit. Therefore, in order to enable the products of different manufacturers to communicate and cooperate with each other, the major manufacturers jointly form a digital family alliance to develop many common connection standards. Including open service gateways (OSGi) and universal plug-and-play services (universal piUg and piay, UPnP) 〇 open service gateway organization was established in March 1999, including international business machines International Business Machines Corporation (IBM), Motorola, Philips (PHILIPS), Bayerische Motoren Werke (BMW), Sony Corporation, and Toshiba (TOSHIBA) Vendors, whose primary purpose is to define an open and integrated service platform that can be used by remote service providers, service developers, software vendors, gateway controllers, and device manufacturers to develop or deploy platforms on the local side. Network and device services. 201215050 According to the standards defined by the open service closed-circuit device, this platform architecture should include the service layer and the dependency module layer, the hybrid life-cycle layer, the service layer and the security layer. Due to the combination of these levels, this trait has the characteristics of being compatible with different (four) devices. Unlike traditional services, which are only available in single-hardware or unified systems, service providers have to develop different service systems for different devices. Open service gateways reduce the time required for vendor development. In addition, it provides a standard application interface, service providers can develop services based on this interface, and through this standard interface, service software and devices developed by different vendors can communicate and match each other; Through its remote capabilities, service providers can provide device management and updates over the Internet; therefore, 'open service spurs ^ standard _ set, promote the connectivity and extensiveness of network services' and provide assistance to existing A development-oriented platform for architecture extensions. Universal Plug and Play service is a set of network protocol proposed by Tong (4) with the forum (the chest & _). Its purpose is to enable home devices to connect to each other through the home network for data sharing, communication and communication. Entertainment, which is a peer-to-peer standard for plug-and-play open protocols defined on IP networks, mainly by Transmission Control Protocol/Internet Protocol (Transmissi〇nc〇ntrol Pmtoed/Intemet Ρ_4 TCP/IP), hypertext The Hypertext Transfer Protocol (HTTP), the extensible markup language _ such as [[10] job feed, XML) and other current common standards are constructed to support many different physical layer transmission media, such as Ethernet. Detach 1394, infrared (1 spoke (1, 111), power line (1) 〇 old 1 ^) and radio frequency (1 ^ 〇 frequency, RF). According to the standard, the four-way device (4) allows the device and the multimedia material to have independent 201215050. Through the control interface of the webpage, the same multimedia can be transmitted and played on different devices without any additional equipment. As long as (4) the device is designed to meet the requirements of the plug-and-play protocol, and plugged into the socket to start, the home device can automatically become a network member, and can immediately provide services through the home network. As mentioned above, the open service gateway and the universal plug-and-play service can bring good development and progress to the network and information appliance connection. However, according to the development of the bribery department and the communication industry, the group is expected to The Consumer Market Report of the Innovative Application Service jointly implemented by the Industry and Technology Support Office and the Information Market Intelligence Center of the Consortium, the financial services of the future, pointed out that the digital lifestyle that consumers imagine in the future is based on the need of “anytime, anywhere”. The current development of the two standard technologies is limited to the home network, and the system is not at home. In the case of the home network environment, there is no service situation and product development. Recently, some manufacturers (such as Sony Corporation) have proposed the so-called "L〇cati〇n Free" concept, which means that "as long as you watch TV programs in your own home, you can watch them whenever and wherever you want." Therefore, from the user's point of view, if these standard services can be used to extend the limit of time and place restrictions, the open service gateway in the home is regarded as the service provider, and the user is also outside. Can perform most of the functions of the service, provide remote multimedia instant transcoding service, and with universal plug-and-play technology, can manage, set, listen or view different universal plug-and-play multimedia devices, allowing users You can make good use of your home resources anywhere. You don't have to rely on other services, you will be able to enjoy the diversity and convenience of services. SUMMARY OF THE INVENTION The present inventors have in view of the shortcomings of the current open service gateways and universal plug-and-play devices that cannot cooperate with each other in 201215050 to provide remote multimedia instant transcoding services, and actively proceed to issue The shortcomings of bribery on the upper track have finally developed the invention through continuous trials and efforts. The main purpose of the present invention is to provide a service-type service gateway, which can process and transmit multimedia (4), and to provide a standard and universal plug-and-play standard. The open service gateway includes: - Open service spurs | | Frame 'system open system _ road multiplex specifications development 丨 and an open service gateway service package, including: - Basic service package Block, Yucheng, please transfer the agreement (Hypertext Trans knows her col, HTTP) Wei and provide various open service services and error message output function; General plug-in (four) service package Wei block, system connection control A plug-and-play device that provides universal plug-and-play control point functionality with addressing, discovery, description, control, event notification, and rendering capabilities; and ~曰 unlimited extension service pack functionality Block ' is used to accept and respond to requests for multimedia streaming services. Another object of the present invention is to provide a method for processing and transmitting a multimedia stream, the method comprising: Step A: obtaining a user request file; Step B: selecting an appropriate stream service quality parameter; Step C: requesting the user The file is instantly transcoded to generate a multimedia stream; in 201215050 and step D: the multimedia stream is transmitted to the user. Through the above-mentioned open service gateway and the method of processing and transmitting multimedia streams, the open service gateway and the universal plug-and-play device can be effectively integrated, thereby realizing the multimedia stream with the concept of unlimited audio and video extension. [Embodiment] In order to make the person skilled in the art understand the purpose of the present invention, the preferred embodiment of the present invention will be described in detail below with reference to the drawings. Referring to the first figure, the open service gateway (丨" of the present invention can process and transmit multimedia streams' and support the open service gateway standard and the universal plug-and-play standard, the open service.
