Description
Technical field
The present invention relates to network television fields, and quickly platform method and device is cut more particularly, to a kind of Web TV.
Background technology
According to the mode of TV transmission, TV can be divided into:Cable digital TV (DVBC), Web TV (IPTV),
Satellite television (DVBS S2), radio transmission DTV (DTMB DVBT) and smart television.Wherein, the user of Web TV
Usage quantity accounts for prodigious proportion, and prior art lower network TV cuts platform speed generally relatively slowly, cuts the delay time one when platform
As at least need 200 milliseconds.Within the delay time, there are two types of the processing modes of mainstream at present：One is draw Web TV
Face is parked in current picture frame, and the broadcasting of next video is just proceeded by after institute's switching channels code stream reaches；Another kind is
Web TV picture blank screen carries out the broadcasting of next video after waiting for institute's switching channels code stream to reach.Major part producer at present
The platform business realizing of cutting of Web TV all uses above-mentioned processing mode so that the user experience when cutting platform is very poor.
Invention content
Platform method and device is quickly cut the purpose of the present invention is to provide a kind of Web TV, Web TV is solved and cuts platform
When occur blank screen, frozen frame and cut the platform time it is slow the problems such as, realize network television user when cutting platform without waiting, instantaneously
Platform is cut, ensure that good user experience.
To achieve the above object, platform method quickly is cut the present invention provides a kind of Web TV, included the following steps：
S1 obtains the current channel information of Web TV, the quick of user setting cuts platform dwell time T and continuous quick
Cut number of units mesh X；
S2 controls audio, video data of the Web TV to each X/2 channel before and after server acquisition request current channel,
And unpack in real time, decode audio, video data, decoded audio, video data is cached in the memory of Web TV, wherein X/2
Round up number after expression X divided by 2；
S3, receives user remote controller operation, and platform is cut in startup；If user it is upper it is primary cut after platform in T seconds, press under remote controler
One channel, thens follow the steps S4；
If user it is upper it is primary cut after platform in T seconds, press the previous channel of remote controler, then follow the steps S5；
