Abstract
The invention discloses a method and a system for switching TV channels. After a TV program receiving terminal receives and decodes the program of a first channel, which is then switched to a subsequent second channel to an Nth channel in sequence; after each switching, the program of the corresponding channel is received and decoded and the first frame image of a decoding program is temporarily memorized; wherein, N is the channel number that can be received by a movable TV terminal; the TV program receiving terminal joints and converts the first frame images of the decoding programs of all the channels to form an image to be displayed; if the TV program receiving terminal is judged to carry out selection on the channels, then the channel selected is switched to, outputting the TV program; or the program of each channel is continuously received and decoded; and jointing display is carried out on the first frame image of the decoding programs of all the channels for a user to select. The system and the method provided by the invention can briefly show the program contents of a plurality of channels which are broadcasting to the TV terminal at one time and lead the user to quickly select.
Description
Technical field
The invention belongs to communication technical field, relate in particular to the method and system that a kind of television channel switches.
Background technology
In recent years, along with expanding economy, development of technology, the function of terminal from strength to strength, a lot of terminals has had the function of received television program, comprises fixed terminal, portable terminal etc.People's life has greatly been enriched in the development gradually of the TV functions of terminal.At present many terminals with TV functions are arranged on the market, can watch the program of several television channels, made things convenient for people to obtain up-to-date information whenever and wherever possible.
In order to be implemented on the terminal switching to television channel, existing way is: after TV functions starts, terminal can only once show the program of a channel, and in the time need checking the TV programme of other channel, need television terminal switching channels one by one, if channel quantity is more, then television terminal just can switch to the channel that operation user oneself likes through a period of time more of a specified duration, and user experience is not good.
So, how to make the user can understand the content of all channel broadcast items fast, select thereby make fast, make things convenient for the user to find apace oneself to want the programme content of seeing, become the problem that the technical staff considers.
Summary of the invention
Technical problem to be solved by this invention provides the method and system that a kind of television channel switches, solve that television channel switches inadequately intuitively in the prior art, problem easily, reduce image flicker, realize the content of each channel is dynamically presented to user terminal.
