“…In addition, a multiplexing of the audio and video signals was done by setting up a TS file in the MPEG-2 standard. The MPEG-2 standard defines how audio, video and data components can be combined into a single file, which is called multiplexing [8]. The multiplexing, besides being done with audio, video and data components can be used to multiplex more than one TS to take advantage of the hierarchical transmission, and to send one or more programs at the same time.…”

Abstract-This work presents a technique for assembling a TS (Transport Stream) file, in accordance with the ISDB-Tb (Integrated Services Digital Broadcasting Terrestrial Brazilian) standard, in order to transmit it through a digital TV signal generator to analyze the parameters variation effects of the ISDB-Tb system in the BER (Bit Error Rate) performance. For this analysis, measurements were taken in three different communication channels, with distinct features. In each channel, the 16QAM and 64QAM modulations were evaluated, and several combinations were tested among the following parameters: operating mode, code rate, guard interval and time interleaving. Also, BER measurements were taken for a C/N (Carrier to Noise) range, set from transmitter, then the Eb/No ratio was calculated, which allowed to plot curves for each measure.

“…The null TSP insertion maintains a constant BTS bit rate signal independent of the modulation parameters and channel coding. The packet order is required to secure the hierarchical transmission in a single TS and to minimize processing at the receiver [6]. The BTS signal is structured in a multiplexing frame in which the number of TSP depends on the mode and guard interval (GI) as can be seen in Table I [1], [2].…”

. The ISDB-T B modulation system can be divided into three stages composed of the re-multiplexor, the channel encoder, and the modulator as can be seen in Fig. 1. The ISDB-T B modulator cannot be configured locally and depends on the multiplexer/re-multiplexer to control and configure all the processing stages. To illustrate the operation of these stages, this article presents a software simulation of the ISDB-T B modulator.From the Broadcast Transport Stream (BTS) that is generated in the multiplexing/re-multiplexing stage, all blocks that compose the modulator are described and analyzed using this computational tool. This simulator allows the monitoring of the input and output of all blocks in supported file formats with Matlab, C/C++ and support for Field Programmable Gate Array (FPGA). In addition, RF vectors can be created that can be transmitted by arbitrary signal generators. Fig. 2 shows a screenshot of this software, in which it is possible to select the file format, processing block, signal generator type and simulation time.Thus, a review of the re-multiplexing stage is carried out in Section II. In Sections III and IV, the coding and modulation stages are presented. In Section V, the simulation tool is evaluated using an arbitrary signal generator and spectrum analyzer with an ISDB-T B demodulator. Finally, in Section VI the conclusion is presented. II. RE-MULTIPLEXINGTo synchronize all the layers between the system source coding and modulation, the MPEG-2 TS 188 byte [4] from the source coding scheme, data carousel, etc. is multiplexed and re-multiplexed. The output of re-multiplexer is formed by a single TS with a size of 204 bytes and constant bit rate of four SET INTERNATIONAL JOURNAL OF BROADCAST ENGINEERING -SET IJBE v. 1, Article 3, 11p.

“…BTS is composed of the TSP from each layer and null packets, called BTS frames. The packets must be ordered to guarantee the hierarchical transmission of a single TS and to minimize processing by the receiver [12]. The null packets are inserted to maintain the constant bit rate independent of the modulation parameters [11].…”
