Abstract
The utility model discloses a receiving device for mobile television, including a receiving module for television, an audio and video processing unit and a transmission module. The audio and video processing unit is connected with the back of the mobile television receiving module and is used to finish de-multiplexing, combination and decompression of television signal and video format conversion. The transmission module is used to transmit the processed mobile television signal to a mobile terminal. The receiving device for mobile television provided by the utility model can reduce CPU load of the mobile terminal, decreasing the configuration requirement for the mobile terminal, and realizing mobile television function of the mobile terminal without high configuration.
Description
Technical field
The utility model relates to TV domain, relates in particular to a kind of receiving system of mobile TV.
Background technology
Along with 3G (Third Generation Mobile Communication, being about to 3G (Third Generation) Moblie) come, mobile TV has become the emphasis of a development, though present mobile TV also can't be compared with emerging services such as multimedia message, CRBT, but 3G opens the increase that means speed, and it is the emphasis of development 3G that video traffic is generally acknowledged.So-called " mobile TV ", the business of utilizing portable terminal to watch TV exactly with operating system and video capability.Obviously, (for example mobile phone, PDA (Personal DigitalAssistant because portable terminal, the personal digital assistant) etc.) user's popularity rate height and portable terminal have characteristics such as easy to carry, and mobile TV service has demonstrated than common TV influence power widely.
Industry is existing by inserting mobile phone SD (Secure Digital Memory Card at present, the secure digital storage card) RF of draw-in groove (Radio Frequency, radio frequency) receiver is realized mobile TV service, but need to come the file decoding of high compression ratio is become the file of low compression ratio by powerful mobile phone CPU, go back the original video image TV reception.This type of receiver and be used for existing sale of SD card product existing market of mobile phone, but their a common shortcoming is: what they exported all is the MEPG-2TS stream of standard, unpack, functions such as demultiplexing, analytical capabilities, decompression finish on mobile phone all, therefore need mobile phone very powerful CPU, high power consumption are arranged, than the strong solution sign indicating number ability and the analytic ability of complicated mobile TV transmission frame.This is the weakness of portable terminals such as present most of mobile phone.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of receiving system that reduces the mobile TV of the configuration requirement of portable terminal.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the receiving system that a kind of mobile TV is provided, it comprises the mobile TV receiver module, and it also comprises the audio frequency and video processing unit of the demultiplexing that is used to finish TV signal, merging, decompression and the video format conversion that are connected to described mobile TV receiver module back in turn and is used to transmit the transport module that treated mobile television signal is given portable terminal.
Described audio frequency and video processing unit comprises successively the demultiplexing module that being used to of connecting isolates multi-channel program, isolates audio frequency, video and the data of each road program; Be used to merge the merging module of audio frequency, video and the data of each road program; Be used for decompression module that each the road programme signal after merging is decompressed; With the video format conversion that is used for high compression ratio be the video format conversion module of the video format of low compression ratio.
The beneficial effects of the utility model are: because the receiving system of mobile TV of the present utility model has been finished demultiplexing, merging, decompression and the video format conversion of TV signal, therefore alleviated the CPU burden of portable terminal, thereby can reduce the configuration requirement to portable terminal, making in configuration is not can realize seeing mobile TV capabilities on the very high portable terminal yet.
Description of drawings
Fig. 1 is the functional block diagram of receiving system of the mobile TV of the utility model embodiment.
Fig. 2 is the functional block diagram of audio frequency and video processing unit shown in Figure 1.
Embodiment
See also Fig. 1, the receiving system of the mobile TV of the utility model embodiment comprises mobile TV receiver module, audio frequency and video processing unit and the transport module that connects successively, and described mobile TV receiver module comprises antenna, Receiver Module and the demodulation module that connects successively.The receiving system of the mobile TV of the utility model embodiment also is included as the power module that each functional module of described receiving system provides power supply.Antenna is used for the received RF TV signal; Receiver Module is used for converting radio television signal to medium-frequency TV signal; Demodulation module is used for converting medium-frequency TV signal to baseband signal; The audio frequency and video processing unit is used to finish demultiplexing, merging, decompression and the video format conversion of TV signal; Conversion and transmission signals that transport module is used to finish with mobile terminal interface are given portable terminal, and transport module can be USB interface, SD interface, bluetooth, WIMAX etc.
See also Fig. 2, the audio frequency and video processing unit comprises demultiplexing module, merging module, decompression module and the video format conversion module that connects successively.Demultiplexing module is used to isolate multi-channel program (as first, second and third ... programs), isolates audio frequency, video and the data of each road program; Merge audio frequency, video and data that module is used to merge each road program, as I frame, P frame, the B frame of video; Decompression module is used for each the road programme signal after merging is decompressed, as decompress(ion) H.264; The video format conversion that the video format conversion module is used for high compression ratio is the video format of low compression ratio, as will H.264 converting MPEG-2 to.
The operation principle of the receiving system of the utility model mobile TV is as follows:
Antenna is sent to Receiver Module with the radio television signal that receives, Receiver Module converts radio television signal to medium-frequency TV signal and is sent to demodulation module, demodulation module converts medium-frequency TV signal to baseband signal and is sent to the audio frequency and video processing unit, and the audio frequency and video processing unit is finished demultiplexing, merging, decompression and the video format conversion of TV signal; Finish with the conversion and the transmission signals of mobile terminal interface by transport module then and give portable terminal, teleview by portable terminal at last.
The audio frequency and video processing unit of the receiving system of the utility model embodiment mobile TV can adopt high speed processors such as DSP, CPU, ASIC.
When the receiving system of the utility model mobile TV and portable terminal cooperating, portable terminal needs control corresponding (search, channel selection etc.) recognition interface signal, finishes the software of video playback and supports.
The above; it only is preferred embodiment of the present utility model; be not to be used to limit protection range of the present utility model, all any modifications of within spirit of the present utility model and principle, being made, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
