Problems solved by technology

Although the channel switching time is shortened as much as possible by adjusting time slice parameters, source coding parameters, etc.; due to the lack of return channels, some interactive improvement technologies cannot be used for multimedia communication to shorten the channel switching time
Therefore, there is no technology that can effectively shorten the channel switching time

Embodiment Construction

[0044] The technology of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Referring to FIG. 1, FIG. 1 is a diagram of an apparatus for realizing fast channel switching according to an embodiment of the present invention. In Figure 1, the switching control unit is connected to the user behavior statistics unit and the adjacent channel searching unit; the receiving unit is connected to the channel content caching unit and the channel content playing unit; the switching control unit is connected to the receiving unit.

[0046] In practical applications, the switching control unit can interact with the user behavior statistics unit and the neighboring channel search unit, so that the user behavior statistics unit and the neighbor channel search unit learn current channel information and user channel switching history records.

[0047] From the learned history of user channel switching, the user behavior statistics unit can o...

Abstract

The invention discloses a device and a method realizing fast switching of channel, both of which can ensure a forecast channel with switching possibility and receive and cache channel content of the forecast channel; when the objective channel to be switched is the forecast channel, the invention can broadcast cached channel content of the forecast channel and switch to the forecast channel. Thus, as the device and the method provided by the invention realizing fast switching of channel can pre-determine the forecast channel to be switched and cache the content of the forecast channel, the cached content of the forecasting channel can be broadcasted previously when the follow-up forecast channel is to be switched, while realizing channel switching. The device and the method can significantly save time of switching channel directly, thereby effectively shortening time consumption of channel switching felt by user and then significantly improving user satisfaction.

Description

Technical field [0001] The present invention relates to mobile communication technology, in particular to a device and method for realizing rapid channel switching. Background technique [0002] In mobile multimedia communications, the length of channel switching time is critical to user experience. Although the current channel switching time is shortened as much as possible by adjusting time slice parameters and source coding parameters; however, due to the lack of return channels, some interactive improvement technologies cannot be used for multimedia communications to shorten the channel switching time. Therefore, there is no technology that can effectively shorten the channel switching time. Summary of the invention [0003] In view of this, the main purpose of the present invention is to provide a device and method for fast channel switching, so as to effectively shorten the channel switching time. [0004] In order to achieve the above objective, the technical scheme of th...
