IBM39STB130X0 stb130x0 a/v transport/decoders ordering information page 2 of 22 stb130x0_sds_080900.fm.05 sept. 7, 2000 conventions and notation throughout this document, ibm notation is used, meaning that bits and bytes are numbered in ascending order from left to right. thus, for a 4-byte word, bit 0 is the most significant bit and bit 31 is the least significant bit. overbars, e.g. txenb, designate signals that are active low. numeric notation is as follows: hexadecimal values are in single quotes and preceded by "x" or "x." for example: x0b00. binary values are spelled out (zero and one) or appear in single quotes and preceded by a "b." for example: b10101. settings of a bit or field are binary numbers but are often displayed in tabular form without quotes or the pre- ceding "b." for example: 00:30 frames per second 01:15 frames per second 11:10 frames per second throughout this document, the word "device" refers to the ibm stb130x0. ordering information ibm part number audio mpeg-2 layer i and layer ii audio dolby digital ibm39stb13000pfa16c yes no ibm39stb13010pfa16c yes yes 1 1 this part includes dolby digital enabling software and requires the user to obtain a license fromdolby laboratories licensing cor- poration. please see dolby digital licensing on page 3

IBM39STB130X0 stb130x0 a/v transport/decoders stb130x0_sds_080900.fm.05 sept. 7, 2000 architecture and subsystem information page 5 of 22 transport demultiplexer the transport demultiplexer performs mpeg-2 transport stream parsing to extract packetized elementary streams (pes) for the audio and video decoders. it provides a full set of demultiplexing functions, including synchronization, pid filtering, clock recovery, table section filtering, crc checking, and data management. these basic functions are configured by the application and implemented in hardware for improved perfor- mance and to minimize the impact on the remainder of the system. the transport demultiplexer is compliant with iso/iec 13818-1 system layer standard, and operates at up to 160 mbps (parallel) or 60 mbps (serial) maximum continuous input rate. mpeg-2 transport synchronization the transport demultiplexer accepts either parallel (8-bit) or serial data. it detects the synchronization charac- ter and establishes transport packet boundaries. in the case of serial input, where only a bit clock is provided, it also establishes byte alignment. there are input controls for error flagging and to force packet alignment if already established by a previous device. pid filtering up to 32 programmable packet identifier (pid) values are used to filter the transport stream. the pid filter associates a 5-bit pid index with each of the 32 entries. entries in the pid filter can be disabled by writing the null pid value. pid index 31 is reserved for the video pid, pid index 30 is for the audio pid. all other values are defined by the application. clock recovery the transport demultiplexer assists in recovering the program clock from the transport stream. it extracts pro- gram clock references (pcrs) from the indicated pid, calculates the offset from the current system time clock (stc) value, and compares it against a threshold defined by the application to determine if clock fre- quency correction is required. the demultiplexer can either filter the clock difference directly, using a simple hardware algorithm, or it can provide an interrupt to allow the application to filter the difference. the output of the filter is loaded into a pulse modulating register, and the serial pulse train output is used to regulate an external voltage-controlled crystal oscillator (vcxo) or similar device. time base changes when a system time base change occurs in the pcr pid stream, the transport demultiplexer automatically loads the stc with the new time base value. the first audio and video packets which arrive after the system time base change are marked. the transport indicates the first data byte following the time base change to each decoder. table section filtering the transport demultiplexer hardware can filter table sections, which reduces the processing load on the application and minimizes the size of temporary work spaces in system memory.
IBM39STB130X0 stb130x0 a/v transport/decoders architecture and subsystem information page 6 of 22 stb130x0_sds_080900.fm.05 sept. 7, 2000 up to 64 different 4-byte filter blocks consisting of a bit pattern and a bit mask can be defined by the applica- tion. section filters can be constructed from one or more filter blocks to provide deep filtering into a table sec- tion. multiple section filters can be attached to a single pid. filter blocks can be assigned to the 32 pid indexes as needed by the application. the filtering mechanism supports multiple sections per packet as well as sections that span multiple packets. error handling the transport demultiplexer simplifies the system-level tasks of error handling and time base (stc) changes by using the compressed data connection to communicate directly with the decoders. errors are detected and flagged in the data stream, allowing the decoders to mask the error and recover without system intervention.
