Description
Technical field
The utility model relates to a kind of Internet video decoding device.Relate in particular to a kind of card insert type high-definition network video decoding device.
Background technology
H.264 be the high compression digital video coding-coding device standard that proposes by the joint video team that ITU-T video coding expert group and ISO/IEC dynamic image expert group constitute jointly.
H.264 characteristics and advantage:
1. higher code efficiency, compression compared with techniques such as code check lower and MPEG2 and MPEG4ASP under equal picture quality, adopt the data volume after the technique compresses H.264 to have only 1/8 of MPEG2,1/3 of MPEG4.
2. H.264 high-quality image can provide continuous, smooth high quality graphic.
3. fault-tolerant ability is strong, and H.264 wrong essential tool such as solving under the unstable network environment incidental packet loss is provided.
4. network-adaptive property is strong, and H.264 network abstract layer (Network Abstraction Layer) is provided, and makes H.264 file transmission on heterogeneous networks easily (for example the Internet, CDMA, GPRS, WCDMA, CDMA2000 etc.).
PCI-E (PCI-Express) bus is up-to-date bus and interface standard, and it is proposed by Intel, transfers to PCI-SIG authentication issue.This new standard replaces existing PCI and AGP comprehensively, finally realizes the unification of bus standard.PCI-E has adopted at present popular in the industry point-to-point connected in series; Shared parallel architecture compared with PCI and more early stage computer bus; Each equipment all has the special use of oneself to connect; Need be, and can bring up to a very high frequency to data transmission rate to whole bus request bandwidth, reach PCI the high bandwidth that can not provide.In the single time cycle, can only realize one-way transmission with respect to traditional PCI bus, two single worker of PCI-E connects the transmission rate and the quality that can provide higher, and the difference between them is similar with half-duplex and full duplex.PCI-E is that a kind of bidirectional linked list connects.Up-to-date PCI-E 3.0 standards rise to 8GHz|8GT/s with data transmission rate.The unidirectional bandwidth of PCI-E 3.0 framework single channels (x1) can be near 1GB/s, and the two-way bandwidth of 16 channels (x16) can reach 32GB/s especially.PCI-E3.0 has also increased 128b/130b decoding mechanism simultaneously especially, can guarantee almost 100% efficiency of transmission, and comparing before this, the 8b/10b mechanism of version has promoted 25%.
Several frequently seen standardized images form:
1.QCIF，176×144。
2.CIF，352×288。
