Abstract

A screen casting method is applied to a source device having a display and a speaker. The screen casting method includes receiving first data and decoding the first data, displaying the decoded first data through the display and/or outputting the decoded first data through the speaker, receiving text information from the server and parsing the text information, and displaying the parsed text information through the display, where the text information is associated with the first data. A first operation of performing screen casting to a target device is detected, and in response to the first operation, sending a download address of the first data and a download address of the text information to the target device.

First claim

What is claimed is:

1 . A screen casting method, applied to screen casting from a source device to a target device, the source device having a first display, the target device having a second display, wherein the method comprises:
receiving, by the source device, a-video data from a server and decoding the video data, and displaying the decoded video data through the first display; receiving, by the source device, a scrolling comment information from the server and parsing the scrolling comment information, and displaying the parsed scrolling comment information through the first display, wherein the scrolling comment information is associated with the video data; detecting, by the source device, a first operation of performing screen casting to the target device, the first operation is configured for screen casting of the video data and the scrolling comment information together; in response to the first operation, receiving, by the target device, the video data and the scrolling comment information from the server according to a first download address of the video data and a second download address of the scrolling comment information; displaying, by the target device, both the video data and the scrolling comment information through the second display; detecting, by the source device, a second operation of sending first edited scrolling comment information; and in response to the second operation, additionally displaying, by the target device, the first edited scrolling comment information in the scrolling comment information, wherein the first edited scrolling comment information is associated with the video data.

2 . The screen casting method according to claim 1 , wherein the video data is a video stream, wherein the scrolling comment information and the first edited scrolling comment information are displayed in a superimposition manner on the video stream displayed on the second display, wherein the scrolling comment information is associated with the video stream in terms of time, and wherein the first edited scrolling comment information is associated with the video stream in terms of time.

3 . The screen casting method according to claim 1 , wherein the method further comprises:
downloading, by the target device, a first part of the video data by using the first download address, and displaying, by the target device, the first part of the video data through the second display; and downloading, by the target device, the scrolling comment information by using the second download address, and displaying, by the target device, a first part of the scrolling comment information on the second display in a superimposition manner, wherein the first part of the scrolling comment information is associated with the first part of the video data in terms of time.

4 . A screen casting method, applied to a source device having a display, wherein the method comprises:
receiving video data from a server and decoding the video data, and displaying the decoded video data through the display; receiving scrolling comment information from the server and parsing the scrolling comment information, and displaying the parsed scrolling comment information through the display, wherein the scrolling comment information is associated with the video data; detecting a first operation of performing screen casting to a target device, wherein the first operation is configured for screen casting of the video data and the scrolling comment together; in response to the first operation, transmitting, to the target device, first information indicating a first download address of the video data and a second download address of the scrolling comment information, such that upon receipt of the first information, the target device displays both the video data according to the first download address and the scrolling comment information according to the second download address; detecting a second operation of sending edited scrolling comment information; and in response to the second operation, transmitting, to the target device, the edited scrolling comment information, such that upon receipt of the edited scrolling comment information, the target device additionally displays, the edited scrolling comment information in the scrolling comment information, wherein the edited scrolling comment information is associated with the video data.

5 . The screen casting method according to claim 4 , wherein the video data is a video stream, wherein the scrolling comment information and the edited scrolling comment information are displayed in a superimposition manner on the video stream, wherein the scrolling comment information is associated with the video stream in terms of time, and wherein the edited scrolling comment information is associated with the video stream in terms of time.

6 . The screen casting method according to claim 4 , wherein the method further comprises:
sending a display parameter of the scrolling comment information to the target device, wherein the display parameter comprises at least one of a font, a font size, a color, transparency, an animation speed, and a display area of displaying the scrolling comment information.

7 . The screen casting method according to claim 4 , wherein the method further comprises:
detecting a third operation of terminating screen casting to the target device; and receiving an updated display parameter of the scrolling comment information from the target device, wherein the updated display parameter comprises at least one of a font, a font size, a color, transparency, an animation speed, and a display area of displaying the scrolling comment information.

8 . The screen casting method according to claim 4 , wherein the method further comprises:
downloading, by the target device, a first part of the video data by using the download address of the video data, and displaying, by the target device, the first part of the video data through a second display of the target device; and downloading, by the target device, the scrolling comment information by using the download address of the scrolling comment information, and displaying, by the target device, a first part of the scrolling comment information on the second display in a superimposition manner, wherein the first part of the scrolling comment information is associated with the first part of the video data in terms of time.

9 . A screen casting method, used for screen casting on a target device having a display, wherein the method comprises:
requesting, by using a first download address of video data, a server to deliver the video data; requesting, by using a second download address of scrolling comment information, the server to deliver the scrolling comment information, wherein the scrolling comment information is associated with the video data; displaying both the video data and the scrolling comment information through the display; receiving first edited scrolling comment information, wherein the first edited scrolling comment information is configured to be sent from a source device that is screen casting to the target device; and displaying, in response to receiving the first edited scrolling comment information, the first edited scrolling comment information in the scrolling comment information, wherein the first edited scrolling comment information is associated with the video data.

10 . The screen casting method according to claim 9 , wherein the video data is a video stream, wherein the scrolling comment information is displayed in a superimposition manner on the video stream displayed on the display, wherein the scrolling comment information is associated with the displayed video stream in terms of time, an
