The mode of acquisition for mobile terminal TV service has two kinds, can pass through the conventional digital radio network, and the Internet, in addition, realizes that the TV programme broadcasting needs the hardware unit on the conventional set-top box platform and software service to be transplanted in mobile terminal.Hardware unit on the conventional set-top box platform is transplanted to mobile terminal can make the hardware cost of mobile terminal increase, and, in actual applications, but the modification of TV service control interface increase be subject to code whether open, with the restriction of the problems such as communication of platform provider, so just greatly reduce the flexibility of developing playout software on mobile terminal device.
A kind of method that the embodiment of the present invention provides program to play, it can comprise: the transmit flow data of receiving front-end server transmission, carry the transmit flow data group character in described transmit flow data; The transmit flow data group character of carrying according to described transmit flow data is carried out soft parsing and decoding to described transmit flow data, obtains the audio, video data for playing; Play described audio, video data.The method of the embodiment of the present invention can be preferably by received terrestrial digital broadcasting class service operation on the intelligent mobile terminal system platform, complete the TV programme broadcasting work under the part receive mode, do not increase hardware cost, there is flexibility.
Below in conjunction with the drawings and the specific embodiments, the technical scheme of the embodiment of the present invention is elaborated.
One embodiment of the method that as shown in Figure 1, a kind of program provided by the invention is play can comprise the following steps:
Step S110, the transmit flow data of receiving front-end server transmission.Wherein, the main body of the transmit flow data of embodiment of the present invention receiving front-end server transmission is mobile terminal device, and the mobile terminal that the embodiment of the present invention adopts has the function that receives transmit flow data from front-end server.Wherein, carry the program data group character in the transmit flow data that this step receives, and this receive mode is the part receive mode.
The part receive mode can comprise ISDB-T One-Seg receive mode, there is no PAT Program Association Table (stream had does not have PAT Program Association Table, PMT Program Map Table) in the transmit flow data received based on ISDB-T One-Seg receive mode, make the decoding process of prior art to obtain programme information by the PAT Program Association Table.The transmit flow data that the method for the embodiment of the present invention can receive the part receive mode by the software in mobile terminal is resolved, is decoded, and carries out the program broadcasting.
Step S111, the program data group character of carrying according to transmit flow data is carried out soft parsing and decoding to transmit flow data, obtains the program audio video data for playing.This step can specifically be implemented by following steps: according to the soft analytical propagation flow data of program data group character, obtain Basic Flow data and audio/video decoding group character; To the Basic Flow decoding data, obtain the program audio video data for playing according to the audio/video decoding group character.
In specific implementation, according to the soft analytical propagation flow data of program data group character, obtain the Basic Flow data and the audio/video decoding group character can comprise: remove the redundant information of transmit flow data, and invalid data; Obtain the Basic Flow data from the transmit flow data of having removed redundant information and invalid data by the program data group character; Judge whether the Basic Flow data comprise Program Map Table; If judge the Basic Flow packet containing Program Map Table, from Program Map Table, obtain the audio/video decoding group character; Do not comprise Program Map Table if judge the Basic Flow data, according to the elementary stream type analysis of stipulating in the packing agreement, go out the audio/video decoding group character.
Transmit flow data under the part receive mode may be increased supplementary, be to increase several bytes after each TS bag, so at first will filter out according to the supplementary of these bytes invalid TS bag, remove the supplementary after effective TS wraps simultaneously, thus outputting standard TS stream.Then, can be with reference to the method shown in the flow chart of Fig. 7, further remove the invalid TS bag in TS stream according to sync byte (0x47) on TS packet header and error of transmission flag bit (transport_error_indicator), obtained removing the transmit flow data of redundant information and invalid data.
Program data group character PID by transmit flow data obtains Basic Flow data ES from the transmit flow data of having removed redundant information and invalid data.Wherein, Basic Flow data ES comprises the audio, video data without decoding, obtain Basic Flow data ES and need extract the PID of the transmit flow data of the program of playing with need from the aforementioned transmit flow data of having removed redundant information and invalid data, the audio frequency and video packetized elementary stream PES(of this program is comprised to audio frequency PES and video PES) carry out obtaining of Basic Flow data ES after extracting.
