This software is provided by : Panasonic Singapore Laboratories Pte. Ltd Author: Liu Jing contact: j liu@psl.com.sg =============================================================================== 1. What is it This software is a MPEG-2 IPMP Transport Stream(TS) multiplexer developed by C. Its basic functionality is to multiplex MPEG-1/2 compatible video|audio and private streams into TS stream. Its advanced functionality includes generate MPEG-2 TS stream with IPMP information, e.g., Tool List, Tool Container, Rights Container, IPMP Descriptor. The produced MPEG-2 TS stream is readable by MPEG-2 compliant terminals. The produced MPEG-2 IPMP TS stream is readable only by MPEG-2 IPMP compliant terminals. 2.Version The current version is 1.0 3. Usage This software has a command-line interface. It requires a parameter file to tell what kind of work to do The basic command-line syntax is: tsmuxer para_file output_file tsmuxer: executable file name of this multiplexer para_file: parameter file name which contains parameters required by multiplexer output_file: file name of output TS stream Advanced usage: some options are provided: -v verbose mode, print some verbose information -a [VIDEO or AUDIO]: this option is used with our Triple DEL Tool desdll.dll. With this option,the multiplexer will encrypt the specified stream type with DES algorithm during the multiplex. e.g., encrypt both audio and video files : -a VIDEO -a AUDIO -k [Keys] : this option is used together with -a to give the keys to be used in the DES encryption, for test reason. currently, we only accept 8 chars[0-9] as *** bit keys. However, the provide DES Tool support ***,128 and 196 bit keys. -n [interval]: this tricky option is used with -a. It gives the intervals of the previous encrypted packet and next to-be encrypted packets. We have this option because encrypt every packets (especially video packets) affects the Terminal side's performance heavily. i.e., the playback Terminal need to decrypt every packet before decode and render. This could beyond some less powerful Terminal's capabilities sometimes. So with this option, we can encrypt data selectively. Examples: a) encrypt Audio stream's every packet (audio is lightweight compared with video) tsmuxer -a AUDIO -k 12345678 -n 1 parameter.txt filename b) encrypt one Video Stream's packet out of every 10 packet tsmuxer -a VIDEO -l 12345678 -n 10 parameter.txt filename When using DES tool to encrypt data stream, users should also put necessary inforamtion in the descriptor data so that the terminal can know where and what key should be used to decrypt the stream. If selective encryption is used, the related information should also be provided in certain ways. Next, we introduce the parameter file used for different multiplex purpose 3.1 Produce simple MPEG-2 TS stream (no IPMP information) a sample profile is given as following: TRANSPORT_RATE 2 dummy 999 PROGRAM 1 dummy 37 VIDEO 2 video1.m2v 40 AUDIO 1 audio1.mp2 50 PROGRAM 2 dummy 38 VIDEO 2 video2.m2v 60 AUDIO 1 audio2.mp2 70 ... END 1 dummy 300 dummy take line "VIDEO 2 video1.m2v 40 "for example: "VIDEO": specify the stream is a VIDEO stream "2": specify the video stream format, "2" means MPEG-2 stream "video1.m2v": specify the stream data "40": specify the stream PID in program stream. It is just a reference, can be changed to any valid integeral number. 3.2 Produce MPEG-2 IPMP TS stream a sample profile is given as following: //IPMP tools information //syntax: IPMP_TOOL Tool_ID=... isAltgroup=... isParametric=... NumUrls=... Url=...; IPMP_TOOL Tool_ID=1 isAltgroup=0 isParametric=0 NumUrls=1 Url=REL.dll; IPMP_TOOL Tool_ID=2 isAltgroup=0 isParametric=0 NumUrls=1 Url=DES.dll; //IPMP Tool Container //syntax: TOOL_CONTAINER Tool_ID=... Format_ID=... Package_ID=... Data_File=...; TOOL_CONTAINER Tool_ID=8 Format_ID=1 Package_ID=10 Data_File=tool_data; TOOL_CONTAINER Tool_ID=9 Format_ID=1 Package_ID=10 Data_File=too2_data; /IPMP Rights Container //syntax: RIGHTS_CONTAINER IsProprietary=... Rights_Tool_ID=... Data_File=...; RIGHTS_CONTAINER IsProprietary=1 Rights_Tool_ID=3 Data_File=rights_data; TRANSPORT_RATE 2 dummy 999 PROGRAM 1 dummy 37 VIDEO 2 /path/video.m2v 40 AUDIO 1 /path/audio.mp2 50 //IPMP Descriptor //syntax: IPMP_DESCRIPTOR Descr_ID=... Elem_ID=... Tool_ID=... CP=... SC=... IsSigned=... Data_File=...; IPMP_DESCRIPTOR Descr_ID=1 Elem_ID=40 Tool_ID=2 CP=1 SC=10 IsSigned=0 Data_File=descriptor_data; END 1 dummy 300 dummy We take the IPMP_Descriptor for further explanation: "IPMP_DESCRIPTOR Descr_ID=1 Elem_ID=40 Tool_ID=1 CP=1 SC=10 IsSigned=0 Data_File=descriptor_data;" Parameters given by above statement are: Descr_ID: this descriptor's ID is "1"; Elem_ID: this descriptor is to protect elementary stream with index "40"; Tool_ID: this descriptor is associated with tool whose id is "1"; CP: specify Control Point of this descriptor. "1" means after demultiplex valid values are: 0 : No control point 1: after demultiplex 2: before decode 3: before render SC: specify Sequence Code of this descriptor is IsSigned: specify whether following descriptor_data is signed or not, "0" means false. Data_File: path of the proprietary data refered by this descriptor. Since there are no IPMP tools have been normalized, the data can be proprietary. Thereafter, the terminal side should be able to read the proprietary data according to its tool id. example: a) produce a global scope descriptor IPMP_DESCRIPTOR Descr_ID=4 Elem_ID=301 Tool_ID=5 CP=0 SC=5 IsSigned=0 Data_File=ipmp_rel.descriptor; "global" is specified by CP=0, which means the control point is set before demultiplex buffer, in this situation, the Elem_ID's value is just used as dummy value. All the other values are still valid. b) produce 2 descriptors apply to same elementary stream IPMP_DESCRIPTOR Descr_ID=5 Elem_ID=40 Tool_ID=5 CP=1 SC=10 IsSigned=0 Data_File=ipmp_tool5.descriptor; IPMP_DESCRIPTOR Descr_ID=6 Elem_ID=40 Tool_ID=50 CP=1 SC=20 IsSigned=0 Data_File=ipmp_tool6.descriptor; Just set the Elem_ID to the stream that this descriptor applies. In above example, there are two IPMP tools will be applied to video stream(PID 40) after demultiplex. One tool has higher priority(sequence code=20) whil the other one has lower priority (sequence doe = 10) 3.3 Produce IPMP Stream This multiplexer also enable user to dynamically generate IPMP stream, which is consisted by multiple IPMP_StreamDataUpdate packets. In our implementation, we generate one IPMP Stream TS packet immediately after PMT table. There will be multiple such TS packet in the finally produced TS stream because PMT table is re-muxed into TS stream every a few seconds(this paramaeter is adjustable). A possible scenario to use IPMP Stream is to carry time variant keys. So user can decide what data to be packed in the IPMP_StreamDataUpdate packet at the time to mux it into IPMP Stream. The IPMP Stream header specified which descriptor should receive this message. At IPMP Terminal side, once IPMP Stream is received, the terminal will extract the message inside and route the message to the IPMP Tools associated with the descritor in the IPMP Stream header. example: use following 2 lines to mux a IPMP Stream 1. IPMP 6 ipmpstream.data 70 2. IPMP_DESCRIPTOR Descr_ID=6 Elem_ID=40 Tool_ID=50 CP=1 SC=10 IsSigned=0 Data_File=ipmp_tool5.descriptor; Line 1 starts with "IPMP", saying this is an IPMP Stream to be muxed. "6" says the stream is to be received by the Tool given in descriptor 6(ID=6). The tool specified in this descriptor is Tool 50(ID=50). "ipmpstream.data" can carry data to be included in the IPMP_StreamDataUpdate packet. "70" is the PID of this IPMP Stream 3.4 Summary A sample parameter file can be like following: //start IPMP_TOOL Tool_ID=1 isAltgroup=0 isParametric=0 NumUrls=1 Url=DESDLL.dll; IPMP_TOOL Tool_ID=3 isAltgroup=0 isParametric=0 NumUrls=1 Url=RELTOOL.dll; IPMP_TOOL Tool_ID=5 isAltgroup=0 isParametric=0 NumUrls=1 Url=DUMMYTOOL.dll; TOOL_CONTAINER Tool_ID=3 Format_ID=1 Package_ID=10 Data_File=tool_data; RIGHTS_CONTAINER IsProprietary=1 Rights_Tool_ID=3 Data_File=License_longValidInterval.XML; TRANSPORT_RATE 2 dummy 999 PROGRAM 1 dummy 37 VIDEO 2 home-text_WM.m2v 301 AUDIO 1 HOME65T.mp2 302 IPMP 2 ipmpstream.data 303 IPMP_DESCRIPTOR Descr_ID=4 Elem_ID=301 Tool_ID=5 CP=0 SC=5 IsSigned=0 Data_File=ipmp_dummy.descriptor; IPMP_DESCRIPTOR Descr_ID=2 Elem_ID=301 Tool_ID=3 CP=0 SC=10 IsSigned=0 Data_File=ipmp_REL.descriptor; IPMP_DESCRIPTOR Descr_ID=6 Elem_ID=302 Tool_ID=1 CP=1 SC=10 IsSigned=0 Data_File=ipmp_DES.descriptor; END 1 dummy 300 dummy //end Explanation: This parameter file tells the muxer following information: 1) mux 3 streams, one MPEG-2 video(PID=301), one MPEG-1 audio(PID=302) and one IPMP stream(PID=303), IPMP stream is going to be received by Tool(ID=3). 2) 3 Tools are to be included in the IPMP Tool List 3) One Tool is carried in Tool Container 4) Rights Data is carried in Rights Container 5) 2 descriptors apply before demux(ID=4 and ID=2) 6) 1 descriptor applies on audio stream after demux 4.Known limitations Current version multiplexer only supports to carry IPMP Tool (with ToolContainer) and Rights Tool(with Rights Container) whose size is less than 4k. This limitation will be corrected at next version. Current version is tested with one program including one video and one audio stream respectlly. Multiple programs and multiple streams are not fully tested. Thanks for using PSL's multiplexer. please send your feedback or questions to the author.
