The present invention provides a switching method of the different display windows of a TV. Before the switching, the TV displays the TV programs, received from the broadcast system and a server, in a main window and a sub-display window respectively, and the switching method includes the following steps that: the TV and the server determine the channel identifiers of the TV programs displayed by each other; the TV displays the TV programs, received from the broadcast system and the server, with the channel identifiers of each other using the first display window and the second display window respectively. By the present invention, the sources of the contents displayed respectively in the first display window and second display window do not change, thereby maintaining the respective display quality (including resolution and picture size) of the two display windows unchangeable before and after the switching.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for switching TV programs shown in different display windows of a TV, comprising: parsing, by the TV, a first TV program from a TV program stream broadcast by a broadcast system, the first TV program being associated with a first channel identifier; displaying the parsed first TV program in a main window of the TV; displaying a second TV program received from a server in a sub-display window of the TV, the second TV program being associated with a second channel identifier; receiving a switching order from a remote controller; sending the switching order and the first channel identifier to the server; receiving the first TV program from the server and displaying the first TV program in the sub-display window; parsing the second TV program based on the second channel identifier from the TV program stream broadcast by the broadcast system and displaying the parsed second TV program in the main window; and wherein the server is separate from the broadcast system, and connects with the TV via the Internet.
2. The method according to claim 1 , further comprising after sending the switching order to the server, receiving from the server the second channel identifier identifying the second TV program displayed in the sub-display window.
3. The method according to claim 2 , further comprising sending the size and/or resolution information of the sub-display window to the server.
4. The method according to claim 1 , further comprising, after the TV sends the switching order and the first channel identifier to the server and before the TV receives the first TV program from the server, parsing the first TV program from the TV program stream broadcast by the broadcast system and displaying the parsed first TV program in the sub-display window.
5. The method according to claim 1 , further comprising parsing the first TV program from the TV program stream broadcast by the broadcast system and displaying the parsed first TV program in the sub-display window, when received and buffered data of the first TV program that are received from the server and displayed in the sub-display window do not reach preset quantity.
6. The method according to claim 1 , wherein the sub-display window displays a TV program preview clip sent from the server.
7. The method according to claim 6 , wherein the TV program preview clip includes a clip of video stream and/or pictures.
8. The method according to claim 3 , wherein a TV program received from the server is processed by the server according to the size and/or resolution information of the sub-display window.
