Photo status and trends of iptv set-top box research - Wafer Check Valve - China Butterfly Valve W
Abstract: The development process can be seen from the set-top boxes in different periods have different functions and roles. In IPTV Rise and mature business process, on the set-top boxes have the new requirements. This article first introduces IPTV set-top box technology solutions and simultaneously analyzed and compared, and then introduced the IPTV set-top box standards of progress and future perspectives of IPTV set-top boxes. In this paper, IPTV set-top box device R & D have some reference.
1, set-top box development process Set-top box (set topbox, STB) originated in the 20th century and the early 90s, when the mainly European and American countries Cable television Taiwan cable TV subscription fees to address the problem of a descrambling device designed. Digital TV set-top boxes as (DTV) ancillary equipment is from the late 20th century Europe and the United States 90 pilot digital TV and high-definition digital TV (HDTV) began. Its main role is to enable users to use existing analog TV to watch digital television programs and high-definition digital TV programs, that provide D / A signal conversion function, usually referred to as digital TV set-top boxes such set-top boxes. Digital TV set-top box has a network of environmental features and conditions of reception. Environmental characteristics of the so-called network television is in different Broadcasting Set-top box used in different network. ETSI defined according to three digital television transmission standard can have: to receive digital cable TV set-top box DVB-C, to receive digital Satellite TV Digital TV set-top box DVB-S, receiving ground Radio and TV Digital TV set-top box DVB-T three types.
Recent years, with the development of broadband networks, Internet applications, more and more widespread, people germination of the idea of using the Internet to watch television. In particular the development of IPTV in full swing driven end markets active Telecommunications Set-top box manufacturers have invested R & D production, the original digital TV set-top box manufacturers are also testing the water two-way IP set-top boxes. Set-top box from a single descrambling or D / A converter dedicated set-top box, developed to support multiple access methods and IP, with a variety of codec capabilities and graphical browsers function, can support, including digital television, including video on demand, when shifted TV, Web browsing, information services, distance learning and medical care, interactive games, IPTV set-top box business functions. IPTV set-top boxes will be coming home as a digital platform is widely used in the growing field of interactive multimedia digital content services.
2, IPTV set-top box technology needs
IPTV business is an entirely new business models, it is set to the consumers of information, entertainment, learning, enjoyment of shopping in one of the network. Personal computers, set-top box + TV or 3G mobile phone IPTV services can be used as the terminal. For the majority of users from the consumption habits and comfort point of view, IPTV set-top box + TV should be the mainstream of the future terminal. Turning to the IPTV set-top box technology needs, this is mainly considered from two aspects, one needs to achieve business, and second, the needs of the user experience.
IPTV service available in a TV broadcast, video on demand, mobile television, video services, information services, Web browsing, interactive games, and possible future expansion of the business. The main features of IPTV services reflected in the form of interactive multimedia retrieval and playback. Require two-way interactive network with the ability to retrieve the needed two-way information exchange. Broadcast Control also requires interactive; player need to have sufficient access bandwidth, and media transfer protocol; multimedia audio and video encoding and decoding capabilities required. Therefore, in order to achieve IPTV business applications, IPTV set-top box required to receive a support network of live TV programming, video on demand, time shift-on-demand and other basic business functions, but also with Internet browsing and information services, electronic program guide (EPG) and program search , as well as interactive games and software upgrades and other online extensions. IPTV set-top box business as a terminal device to an open system architecture to adapt to constantly upgrade and expand the business requirements; full account of the network environment and protocol factors that require not less than two of its upstream network interface, support for multiple access authentication protocol and IP; requires audio and video media encoding and decoding functions, as well as business applications and management functions. In short, IPTV set-top box from a business point of view need to open business with the ability to meet evolving business needs.
Considering the demand from the user experience, IPTV business changes brought about by the traditional Internet PC Terminal view streaming video of the study experience transferred to the living room, the forward backward into a sitting posture, to Keyboard Operation to remote control operation. These changes required the design of IPTV set-top box used to give full consideration to the broad user community television operation, should be kept simple, cost-effective medium and durability characteristics. Different consumption needs of the user. Set-top box should be designed with high, medium and low grades, and meet a variety of levels of consumer groups.
IPTV set-top boxes in the design process to meet these many needs, needs the support of a series of key technologies, including audio and video codec technology, graphics and image display technology, media streaming / Control (protocol), the middleware technology , embedded systems and various interface technology.
3, IPTV set-top box technology program
Early set-top box can only provide video services, technology focus is primarily on the video section. The IPTV service is to achieve the ultimate goal of video, voice and data integration, through the provision of triple play IPTV set-top box business. Because of IPTV set-top box can be provide video, voice and data link integration services, combined with broadband access and wireless network, you can create a truly networked home environment.
IPTV set-top box application process is generally for business content through broadband Internet access to the set-top boxes, using set-top box remote control or remote keyboard, video content to the broadband network request, broadband network will need to send video signals to the client, through the set-top box decoding TV output. VOD or Web browsing.
Support IPTV services are currently available set-top box products generally three grades, namely, basic, enhanced and super-type. The so-called basic model is the basic set-top boxes to support IPTV service, providing electronic program guide, for network television broadcasts, can be the basic playback controls. Enhanced set-top box functionality than a basic model, it can also provide Internet browsing, video services, text information and simple games. The super high-end set-top box-type equivalent

Do I need a check valve on the cold water supply to my washing machine ?
I have a washing machine connected to the cold water supply and I have noticed that there is no check (non return) valve installed. Do I need this or is it just a precaution. Also, does the supply to the outside tap need one too?
Many thanks
