In the embodiment, the entry of multiple category of language is packaged first, the entry of each language is packaged into word
Item packet, rather than be directly directly preset at the entry of multilingual in audio-video terminal.
The step is executed by front end, specifically, being packaged to multilingual type and corresponding entry as follows：
Increase the speech selection descriptor of a description multilingual first in network information table；
Wherein, speech selection descriptor is following format：
{ descriptor, descriptor length, descriptor content }, setting descriptor length refer to the length of descriptor content,
Descriptor content can describe the description with current language and corresponding entry packet numbers, for example English and Chinese are respectively E
(0x45) and C (0x43), it is 0x15 and 0x16 that both language, which are added, to need corresponding data packet, since a letter accounts for 1
Byte, then length is 4, content 0x45,0x15,0x43,0x16.
So current speech selection descriptor can be described as：
{0xA0；0x04；0x450x150x430x16 }, it means that current there are two types of language and describe two kinds of languages in this way
Say corresponding entry data packet.
Secondly, it needs to be packaged into complete data packet after entry is put in order, to be transmitted, according to transport protocol to come
Entry data are packaged.Due to a data packet can only by 188 bytes, wherein preceding 4 bytes are the packet header of standard, after
