摘要： A bit rate converting apparatus suitable for a DVB-H signal which does not have a function of rewriting a PCR value comprises means (42) for receiving a TS signal of a DVB-H standard for storage in accordance with a first bit rate, means (46) for sequentially generating NULL packets in accordance with a second bit rate, and means (45) for outputting a packet which forms part of the stored TS signal from the means (42) and the NULL packet from the means (46) in accordance with the second bit rate. The apparatus may further comprise means (51) for receiving the TS signal of the DVB-H standard to remove NULL packets from the TS signal. Alternatively, the apparatus may further comprise means (61) for receiving the TS signal of the DVB-H standard to pass only a packet representative of a program which constitutes the TS signal, and a PSI/SI packet.

摘要： A method of creating a DVB-H signal having a desired bit rate includes the steps of preparing a TS signal of DVB-H Standard in conformity to a first bit rate (71), storing a burst period (T) of the TS signal and a second bit rate higher than the first bit rate, determining the number (a) of NULL packets to be increased in the burst period (T) (73), storing the TS signal including the number (n) of packets in the burst period in units of packets (74), storing the number (a) of NULL packets next to the stored TS packets (76, 77), and repeating the step (74) and the step (76, 77) until the complete TS signal is stored (75). An apparatus comprises means for executing the steps.
摘要翻译：一种创建具有期望比特率的DVB-H信号的方法包括以下步骤：根据第一比特率（71）准备DVB-H标准的TS信号，存储TS信号的突发周期（T）和确定高于第一比特率的第二比特率，确定在突发周期（T）（73）中要增加的空分组的数量（a）（73），将包括分组数目（n）的TS信号存储在突发周期以分组（74）为单位，存储在所存储的TS分组（76,77）旁边的空分组数（a），并重复步骤（74）和步骤（76,77），直到完整的TS信号为储存（75）。一种装置包括用于执行步骤的装置。
