Master Liang Zhou: STB by hi joiney
Of: Master Liang Zhou Connected to the article: Master Liang Zhou: STB-Card Separation trend (on)
STB Use of software technology Digital TV Instant CA decryption (the absence of computer support to help) need to address two key points: First, to improve the efficiency of the signal processing operations to achieve and TV Broadcasting Synchronized match. Second, CA is not to be broken in order to ensure the security of confidential, can not reduce the intensity of CA Anti-breaking close to improvise storage space limitations and operational efficiency, and can not raise the cost of set-top box (only lower). In addition, long-term development perspective, with the popularization of FTTH further mature and large-capacity storage device for continuously developed, it can play the role of home gateway (this paper omitted).
It was said early in this century alone on this home gateway product came out. Transmission times in the simulation do not agree with the U.S. machine card separation technology, and Europe, keen to Smart Card Technology. The rise of digital transmission, machine card (smart card) separation obviously prevailed. The end of the century European and American made machine card separation program just to meet the different system of measures taken by a technology, now digital, network development prompted Information Development. Digital TV is just one narrow content area in the future not only in the transmission system to integrate the three networks, between different sectors (such as television and telecommunications) to separate the concept of isolation will be broken. TV images show not only as ornamental, it should be used Monitor And interact with a variety of data display used. To achieve this, a variety of resources, including storage resources, data resources, information resources, communication resources, knowledge resources, computing resources, software resources, and even Expert Resource integration, implementation, application should take into account the set-top box to go. Konka Group have already given their set-top box products will be integrated in future Computer , Communications, consumer electronics,, can realize a variety of interactive operations, will be a multimedia entertainment center; Dayang full software development company in strong force on the block, the advantages of the computer and TV together. Establish direction towards triple play from the "home media center"; Huawei Company believes that the development trend of the end product must be the integration of functions from a single terminal to the terminal evolution of integrated intelligence, it is necessary to have the consumer end-product attributes, but also increase the network properties. Only to provide integrated services Operation Business to the next intense Competition To survive, and integrated business positioning to force the terminal manufacturers must have an integrated business and technology integration to provide a variety of capacities. So perfect and reliable terminal software upgrade program is the most important. Huawei proposed terminal set-top box should be "an extension of the network, carrier operations, not a vassal of home appliances, "Huawei to set-top box as a" platform for home media entertainment destination "; well-known companies that Tembec: modular solution can not avoid the CI module Monopoly , Interfaces to the CA IC Card Significant deficiencies in the transfer. They think that the "hardware General Software download "hard and soft separation mode set-top box manufacturing industry will become the mainstream of development.
Software encryption strengths: 1. Can be replaced by real-time encryption and password authentication system, making the system more secure.
2. Opening up the system encryption platform compatibility and openness.
3. Other functions the software can share the same processor, software, technology and resource sharing to achieve a low cost.
Moreover, the network platform has also been limited to the Internet, wired / wireless (including satellite) broadcasting network, will also include the ubiquitous power grid, which is equivalent to achieving grid idea. Then the so-called set-top box, should have high-speed operation, large capacity storage, unified software download update technology, and personal security. This is the future direction of the intelligent home gateway. Spiral technology always follows the law of development, an outcome although the environmental conditions at the time was not sure, but with the evolution of technology and the environment, conditions are ripe, it will also sprouted a new vitality and competitiveness. Related Leadership Departments should focus on the potential development of further work. Therefore, considering the transitional product, must be considered to have favorable prospects for the development of upgrades and space.
In fact, the end of the century You-ping made both academicians to "share the earth", but also to "take what we need" and "Information sunshine" concept has been sketched out the prototype (I wonder if such a set-top boxes and computers have any difference).
With value-added services, the rise of personalized service, meaning the future of digital television will generalize to the digital multimedia interactive home gateway direction.
