Abstract
The embodiment of the invention discloses a method and device for playing video data. The method comprises following steps of determining whether a channel switching instruction triggered by a user is received or not, wherein the channel switching instruction is used for switching a current playing channel and comprises a remote control data switching instruction; determining whether a channel corresponding to the switching instruction is a prediction channel or not if it is determined that the channel switching instruction triggered by the user is received; obtaining and decoding pre-stored playing data corresponding to the channel switching instruction if it is determined that the channel corresponding to the switching instruction is the prediction channel; and playing the decoded playing data if it is determined that the user needs to switch to the channel corresponding to the switching instruction. The time of at least dozens to hundreds of milliseconds from caching the data to decoding the data is reduced; the switching waiting time of the user is greatly reduced; or the user is prevented from missing the highlight happy moment; high speed program switching and displaying can be realized on a set top box; the excellent user experience is brought to the user; and the use efficiency of the user is greatly improved.
Description
Technical field
The present embodiments relate to the technical field of Set Top Box, particularly relate to the side of a kind of playing video data
Method and device.
Background technology
Set Top Box the most more and more comes into common people's daily life, along with increasing of TV programme, quickly
Zapping response speed the most closely become everybody pay close attention to problem, from remote controller press triggering zapping from the beginning of, arrive
TV image display zapping completes, and within zero second, zapping has become as main way from now on.This is that science and technology is to disappearing
The fabulous performance that expense person brings is experienced, but in the market, each producer is all coming by respective way
Complete this sequence of operations, be the most all by multichannel prediction and caching.
At present, the zapping operation of prior art is:
By to programme information before and after programme, carry out look-ahead frequency locking, overstate frequency frequency locking normally
Time all arrives 1500MS 300, if poor signal may be longer；
Pin the red-letter day of frequency, carry out overanxious district of data being delayed in advance in RAM by PID, then by difference
The data of step are thrown away, and carry out synchronization in advance and prepare to play.
Prior art suffers a disadvantage in that prior art can only accomplish reception in advance and the caching of data,
And do not accomplish that decoder participates in solving frame in advance.Such design, when Set Top Box receives infrared signal,
During response zapping, data, from being cached to solution, at least also have the time of tens to hundreds of millisecond to be used in the middle of this
The data parsing of decoder.Here time waits and the experience of quick zero second zapping or defective.
