In
34、order to characterize 3 codecs in typical cdma20001environments, 1 specifies simulation methodology (error 4 insertion devices, network loss-delay models, clips, etc.). 2 provides the necessary software 5 tools such as error insertion devices and network loss-delay models. The H.263 reference 6 enco
35、der / decoder software submitted in this technical report is intended to be used with the 7 software in 2 to characterize video in 3GPP2 multimedia services. 8 2 SOFTWARE DISTRIBUTION FOR H.263 VIDEO CODEC FOR 3GPP2 9 PACKET SWITCHED MULTIMEDIA SERVICES 10 2.1 General Description 11 This software di
36、stribution is in long filename format and will need to be initially downloaded 12 onto a PC-Windowsplatform, and the appropriate portions subsequently transferred to an 13 appropriate platform for processing, depending on the software distribution contents. If the 14 distribution is downloaded as co
37、mpressed files from an ftp site, a free 397 KB space will be 15 required: 89 KB for the compressed files and 308 KB for the uncompressed distribution 16 directory. The utilization of this software database is described below. 17 2.2 H.263 Reference Encoder / Decoder Software Distribution 18 The Soft
38、ware Distribution supporting H.263 baseline (Profile 0) Level 45 is contained in the 19 compressed files accompanying this textual cover. The folder Encoder contains reference 20 encoder source files, and the folder Decoder contains reference decoder source files. 21 3 DECODER 22 The provided H.263
39、baseline decoder software can decode H.263 baseline bitstreams 23 compliant to 3, and network-simulator packetized H.263 baseline streams which are 24 compliant to 1. The network-simulator packetized streams are composed of RTP packet 25 size fields, arrival time fields, and RTP packetized H.263 bas
40、eline streams which are 26 compliant to 4. Also, the provided decoder can detect packet loss using RTP sequence 27 numbers. When packet loss is detected, the error is concealed by using a copy from co-28 located block concealment method. 29 3.1 Decoder Reference Software Executable and Usage 30 The
41、name of decoder executable of the provided software is dh263.exe. Usage of the decoder 31 executable is shown below where it is assumed that the decoder configuration file is 32 decoder.par. 33 dh263.exe i decoder.par 34 1cdma2000is the trademark for the technical nomenclature for certain specificat

The resulting network-simulator packetized streams are composed of RTP 14 pac
45、ket size fields, arrival time fields, and RTP packetized H.263 baseline streams which are 15 compliant to 4. The provided encoder software employs the three-step search 5 for a fast 16 motion search, and a simple mode decision algorithm using a SAD threshold. 17 4.1 Encoder Reference Software Execut
