Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides a kind of video browsing approach, and with reference to Fig. 1, in video browsing approach first embodiment of the present invention, this video browsing approach includes:
Step S10, when receiving multiwindow browsing instructions, obtains the network speed information of terminal;
The video browsing approach that the embodiment of the present invention provides is mainly used in the terminal display to multiple display windows and processes. It should be noted that, this terminal is preferably television set. Above-mentioned multiwindow browsing instructions is the telecommand (telecommand that such as can be inputted by the mode such as remote controller or mobile phone) that user inputs, for controlling the multihead display of terminal, multi-channel image processor instruction or other instructions can also be referred to as in other embodiments, as long as realize the function of multi-channel image processor for controlling terminal. The network speed information of above-mentioned terminal can adopt the network Iperf instrument that tests the speed that networking speeds is tested. When receiving multiwindow browsing instructions, obtain the network speed that Iperf instrument records. Specifically, Iperf instrument is the performance measurement tool of TCP/IP and UDP/IP, network throughput information can be provided, and the statistical information such as shake, packet loss, largest segment and MTU size, it is thus possible to help us to obtain network performance in real time, location network bottleneck, obtains the network speed information of terminal.
Step S20, determines the quantity of display window according to described network speed information;
In the present embodiment, the quantity of the network speed correspondence display window of different phase is different, and each stage correspondence is preset with the display window of one or more varying numbers. Specifically, this display window is UI window, and windowed format can be the window of 3*3 or 4*4. May determine that the display window adopting preset 3*3 displays or adopt the display window of preset 4*4 to display according to above-mentioned network speed information, or adopt the display window of other quantity.
Step S30, generates video acquisition request according to the quantity of described display window, and sends to server;
Step S40, receives the video data that server returns according to the request of described video acquisition, controls each display window and plays corresponding video data.
After determining the quantity of display window, generate video acquisition request according to the quantity of display window, and the request of this video acquisition is sent to server. Specifically, the corresponding video data of each window (namely every window correspondence plays the video frequency program of a television station), video data corresponding for each window will be sent to television set according to the request of this video acquisition by server, then pass through SOC TV chip in television set and resolve multi-path high-definition or SD video data simultaneously, be finally respectively outputted to each display window and display.
When the embodiment of the present invention is by receiving multiwindow browsing instructions, obtain the network speed information of terminal; The quantity of display window is determined according to described network speed information; Quantity according to described display window generates video acquisition request, and sends to server; Receive the video data that server returns according to the request of described video acquisition, control each display window and play corresponding video data; It is achieved thereby that multiple windows show the programme content being currently played simultaneously, therefore improve the speed of video tour.
Further, with reference to Fig. 2, based on above-described embodiment, in video browsing approach the second embodiment of the present invention, above-mentioned steps S20 includes:
Step S21, obtains the number of windows with described network speed information matches;
