UT Starcom Yang: concern IPTV system integration strategy-IPTV, UT Starcom, telecommunications networks – Radio and Television Industry
Both carriers, or TV broadcast operators, IPTV system integration is still a perplexing problem.
System integration is a problem related to the industrial structure. In the structure of the question, how the various related enterprises of various products around the IPTV business activities of production and effective organization, to form a reasonable allocation of resources and enterprise markets, and IPTV is a special property rights structure, market characteristics and closely related to business objectives, not by past experience or subjective industry's imagination can be resolved.
In accordance with the traditional mode of integration of networking equipment, is a long held view that the industry generally. This system integration strategy is based IPTV by "device" module consisting of "open" Internet is made of. The "device" is in accordance with the functionality and interface definitions. Under ideal circumstances, through the establishment of related standards, different equipment manufacturers are developing a variety of equipment to support IPTV, such as head end, set-top box, streaming media servers, content distribution systems, multicast networks, and network management systems, business management systems and user management system, operators of the tasks are relatively simple to achieve the procurement of equipment and networking devices.
This integrated strategy to provide telecom operators in the past self, single, static "communications" business, network construction is a very effective carrier of telephone network, data network, access network and transmission network, radio and television broadcasting the access network operators and transmission network, are so established.
Telecommunication network in the past by the equipment manufacturers and telecom operators, industrial pattern is composed of a single static in this communication business formed under the system. Create a new institutional economics of Coase's concept of transaction cost analysis of the relationship between markets and business organizations, on market economic theory made an important contribution. He believes that business and market allocation of resources can be replaced by each other's way. Enterprise exists because it can reduce the transaction costs, which can replace the market mechanism. The reason is that the operation of the market is cost, and the emergence of business relationship can be by means of its authority by reducing the number of transactions, the market mechanism to achieve more than the efficient allocation of resources. The main difference between the two is reflected in: the market price through the impersonal mechanism of spontaneous, and in the enterprise, it is based on the organizational structure through the administrative authority to achieve, depending on the choice between market transaction costs and the administrative authority of the balance between the implementation of cost. On the other hand, Johnson and McLean further to a modern enterprise as a production function, is the connection point of a series of contracts, including external and internal contractual relationship. This sense of business is artificial, the contractual relationship is based on transaction cost, risk and external market environment and legal environmental constraints on the production function to optimize the result of various factors.
From these theoretical point of view, the existing systems integration strategy is simply to provide a single static environment for effective communications services industry. The IPTV industry environment is entirely different. A very obvious fact is that, due to the complexity and cost of business constraints, IPTV business capabilities can not function with a fixed "equipment" to complete, while the use of specialized business software developers need to provide business-oriented middleware . How the system in this environment to achieve the integration of IPTV operators as common challenges.
IPTV system operators to develop integrated strategies, we must consider the following several interrelated factors: the flexibility of purchasing, new business development (configuration) of convenience and costs, business integration (configuration) of convenience and cost, the convenience of expanded business scale and cost of resources (network, computing power, storage capacity) of reusability, and provide the necessary quality assurance function, security function, copyright management, business management functions such as the complexity and the cost.
Device-level integration point of view, directly affect the "equipment" industry structure. To this end, we first analyze the business Decomposition of IPTV should be horizontal or vertical decompose decomposed. Because this is the premise of the establishment of the industrial environment.
So-called vertical decomposition is the decomposition of the IPTV business is broadcast services, on-demand service (VoD), time has changed business, information services, communication services and games operations were achieved by different subsystems. If there is a new business there, and then add a new subsystem. In the integration process (except for set-top boxes), because each subsystem can be set to complete a separate device, so that each subsystem can be integrated as a separate unit to operate. Do so at the expense of operational flexibility and reuse of computational resources in exchange for the cost of purchasing flexibility.
So-called horizontal decomposition is the decomposition of the IPTV business based transmission network plane, basic computing / storage plane (service nodes and set-top box), spread to send audio and video planes, interactive audio and video service control plane, audio and video content management plane, audio and video, and audio and video service management plane using the plane.
