The digital television and network radio and television practitioners through the development of the past few years hard work has made a series of interim results, but the desired development goals from some distance. So we need to make unremitting efforts. With the Division advances in technology, TV production equipment and technology has been optimized recording equipment has undergone disc recorder cassette tape recorder to the process, to the latest CD used, P2 cards, easy to drive card camera recorder. Mode has also experienced from analog to digital, from linear to nonlinear conversion from single to the network. This from a simple AV to AV and IT integration, reflected in television technology innovation, this integration requirements have become stronger. The post-show television programs produced in the production process plays an extremely important position, directly affects the process of program production, efficiency, quality and other relevant details.
A post-programming the main technical characteristics Post-editing package
synthesis, voice workstations, studio recording, 3D effects processing. Its main features are as follows:
* Perfect network operating platform and management software, multi-low input, high efficiency, high stability of the network structure.
* Powerful centralized data management, and unified management of video and audio material, subtitles, program content, scientific and rational work processes across the network.
* Provide broadcast-quality and more efficient digital recording format for download.
* Late in the non-linear editing, able to support, including multi-format uncompressed including editing, to ensure high-quality programming; in real-time multi-layer video editing, high quality and fast video graphics infinite layer synthesis; provide comprehensive video, audio I / O interface; supported audio formats; to achieve high-quality keying effect; embedded professional titles system in the network to achieve all the features of professional titles; to achieve a variety of documents format output, such as streaming media, VCD, DVD, etc.; support third-party effects plug-ins embedded systems to support third-party applications.
* HD programming in the area, to support editing techniques based on dual-rate HD / SD production.
* Synthesis in the latter part of packaging and support, including multi-format uncompressed program package, including synthesis, video, real-time processing can be achieved Level 4; packaging synthesis system support and program editing system to share the story board exchange program.
* Network trial with a professional video film signal output terminal can be connected directly to the monitor.
* Audio Workstation package can provide complex audio, audio processing.
* In the studio recording, the provision of multi-format signal recording studio, recording material directly to the production network of online storage body.
* In the three-dimensional animation, the provision of fast three-dimensional modeling, simulation, synthesis, supporting cross-platform distributed rendering.
* Provide post-production users, columns, materials, disks, equipment, logs and other aspects of management, support for the production network billing system statistics reporting capabilities.
Two network Networks, digital technology is one of the core network system of networking technology that the network structure, which involves the planning and process management of the network. From the current technical point of view, network computer network technology with the four closely related, they are: High-speed Gigabit Ethernet, ATM Asynchronous Transfer Network, Storage Area Network (SAN) and IPSAN.
1. Gigabit high-speed Ethernet Ethernet technology is 30 years. Its vitality is simple, practical and mature. Ethernet has now developed to a switched Gigabit Ethernet and Gigabit Ethernet. Ethernet LAN is not only a major technical, but also gradually move towards the WAN and MAN.
2. ATM Asynchronous Transfer Network ATM technology not only has a fixed transmission delay and the transmission capacity agreement, and can effectively deal with non-continuous transmission. In the synchronous transfer mode, ATM uses 53 byte fixed-length cell structure, making the process of sending and receiving data to maintain smooth traffic flow stability, more accurately estimate the network latency and execution time and other factors. ATM technology is a connection-oriented data transmission technology, when the sender and the receiver Xiangyao communication, the first requirement to establish a connection to send the control signal, the receiver control signals received through the network and agreed to establish a connection, a virtual line will be established. Meanwhile, the virtual circuit on a relay point for all routes will be established image table, the virtual circuit is established, the necessary information is split into 53 transmitted byte cell, the network sent by the other party. ATM is ideal for video, voice, data and real time transmission of tasks to support the optical fiber, coaxial cable, shielded and unshielded twisted pair, the effective bandwidth is likely close to its nominal value 622Mpbs and 155Mbps. ATM network technology, high cost, often used as the backbone of enterprise networks.
3. Storage Area Network (SAN) SAN Storage AreaNetwork is the abbreviation of its Chinese name of the storage area network, first originated in the large data network backup system. In the typical network structure, the client on the server’s data services through the traditional TCP / IP network to maintain the operation, when the need for disk arrays, database servers, application servers for large data migration between the three, the data directly a dedicated network to run, see SAN is a very unique structure, high-performance broadband networks.
SAN Fiber Channel-based link, FiberChannel given SAN profound meanings, usually, SAN use SCSI protocol, but the FC protocol encapsulated in the package need to run. SAN data storage and transmission more than the SCSI expansion and easy to use. Prior to this, SCSI has been the main platform for massive data transmission, SCSI is a peer to peer technology, the scalability on the not very good.
(1) SAN features A. large-capacity data-sharing device In nonlinear network applications, increasing storage requirements. As the digital television applications, the storage capacity has reached TB-level requirements. SAN provides a high-capacity storage devices to share solutions.
B. multi-stream real-time editing of high speed storage device access requests
With the development of computer technology, the current non-code system has been able to achieve 4 to 6 layers 50Mb real-time editing capability, which requires the transmission speed storage devices must meet the non-linear editing requirements. SAN using fiber-optic network, not only
I am an expert from Cheap On Sales, usually analyzes all kind of industries situation, such as cabinet cigar humidor , cigar cabinets.
