Abstract
The invention discloses a network code stream converter. The network code stream converter comprises a microprocessor, a first memorizer, a work instruction lamp, a FLASH, a PCI (peripheral component interconnect) bridge chip, an Ethernet interface and a decoder are connected to the microprocessor, an IDE (integrated drive electronics) interface is connected to the PCI bridge chip, and a second memorizer and a digital/analog conversion circuit are connected to the decoder. The network code stream converter has the advantage of applicability to MPEG (moving picture experts group)-4 video code stream conversion, is enabled to meet the requirement for television signal output and to have a self-adaptive resource allocation capability, and is high in video image quality.
Description
Technical field
The present invention relates to a kind of code stream transducer, relate to a kind of video code flow transducer for network in particular.
Background technology
Along with development of science and technology, the sharing of media information resource, Internet resources can just need transcoding technology by televising.But, development of internet technology, people are higher to the requirement of video transmission rate and picture quality.Most at present players all move at PC, and its range of application is very restricted.
Summary of the invention
The invention provides a kind of network code stream transformer, the video code flow conversion that it is applicable to MPEG-4 makes its output of satisfying TV signal, and it has adaptive resource allotment ability, and the video image high-quality.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
A kind of network code stream transformer, it comprises microprocessor, be connected with first memory, relay indicating light and FLASH on the described microprocessor, also be connected with pci bridge chip, Ethernet interface and decoder on the described microprocessor, be connected with ide interface on the described pci bridge chip, be connected with second memory and D/A converting circuit on the described decoder.
Further technical scheme is:
Described pci bridge chip, Ethernet interface and decoder all link to each other with microprocessor in the mode of pci bus.
Described microprocessor is TMPR4925XB-200.
Described decoder is VW2010 A/V/S codec chip.
