Problems solved by technology

[0002] With the rapid development of information technology and industry, the transmission network built independently around data, voice, video and other services has the following problems: First, the repeated construction of multiple bearer networks causes additional waste of resources, and the repeated occupation of multi-network projects Limited building space and damage to the natural environment. At the same time, the investment in multi-network equipment also increases the cost of operation; second, most networks are networked by cables, which not only transmits limited information, but also due to the natural deterioration of cable connection performance. , so that the signal transmission is not smooth, resulting in a decline in service quality

Embodiment Construction

[0039] The core of the invention is to provide a method for providing digital high-definition audio / video services to users through the Ethernet passive optical network. Utilize the superior transmission performance and two-way interactive characteristics of the Ethernet passive optical network to complete the broadcasting and sending of digital high-definition programs and interactive on-demand functions.

[0040] The specific implementation plan of the present invention: in the downlink direction, the transmission of IP data packets based on the EPON protocol and the transmission of digital TV services based on the DVB standard are carried on different wavelengths of 1490nm and 1550nm through WDM, thereby greatly simplifying the protocol processing of the system on the complexity. In the uplink direction, the terminal equipment uses the time slot allocated by the OLT unit to send uplink signals through the wavelength of 1310nm.

[0041] Based on the above system solutions, ...

Abstract

The present invention provides an integrated access terminal under the condition of Fiber To The Home (FTTH). The terminal mainly includes a photoelectric conversion unit, an audiovideo signal processing unit and an IP processing unit three main function units, completing the integrated access of video, audio, data services. Digital television service of DVB standard and IP service based on the EPON protocol are loaded on two wavelengths utilizing WDM technology, completing the signal transmission utilizing another three wavelengths. For audio / video businesses, the access system can support DVB, IPTY service modes and two display terminals of television and individual computer, substantial utilizing respective advantages of the DVN, IPTV service video and advantages of television and individual computer as display terminal. In addition, the access terminal system also can complete Internet service and VoIP service access by EPON transport protocols.

Description

technical field [0001] The invention relates to an information access terminal that realizes the integration of multiple information, multiple systems and multiple services under the condition of FTTH. Under the condition of EPON access, a resource sharing, system compatibility, and network integration multi-information operation and operation platform has been created for end users. Background technique [0002] With the rapid development of information technology and industry, the transmission network built independently around data, voice, video and other services has the following problems: First, the repeated construction of multiple bearer networks causes additional waste of resources, and the repeated occupation of multi-network projects Limited building space and damage to the natural environment. At the same time, the investment in multi-network equipment also increases the cost of operation; second, most networks are networked by cables, which not only transmits li...
