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 [0001] The invention relates to a code stream converter, more specifically to a video code stream converter for network. Background technique [0002] With the development of science and technology, the sharing of media information resources, network resources can be played on TV, and transcoding technology is needed. However, with the development of network technology, people have higher requirements for video transmission rate and image quality. At present, most players run on PCs, and their application range is greatly limited. Contents of the invention [0003] The invention provides a network code stream converter, which is suitable for MPEG-4 video code stream conversion to meet the output of TV signals, has adaptive resource allocation capability, and has high-quality video images. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: [0005] A kind of network stream con...
