Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 1 is a schematic flowchart of an embodiment of a method for playing a video on a same screen according to the present invention, where the method includes:
step 11: when the sending end equipment opens the audio and video needing to be played, marking a playing progress graduated scale according to the total duration of the audio and video, and marking the current playing position, namely a marking point, on the playing progress graduated scale;
the audio and video are marked above the corresponding playing progress graduated scale according to the scale unit of the playing progress graduated scale corresponding to the preset unit time value, and the marked points are expressed in a protruding dot or highlight form. Similarly, a scale, that is, a scale with the same attribute, needs to be set in the receiving end device, and both the scale unit of the scale with the same attribute and the unit time value corresponding to the scale unit are the same as the scale unit of the scale with the playing progress and the unit time value corresponding to the scale unit.
The scale units on the scale with the playing progress and the scale with the same attribute are fixed values, the fixed values are set according to actual application conditions, specifically, each scale unit represents 10-60s, in the range, the smaller the scale unit is, the more accurate the positioning is, but the smaller the scale unit is, for example, 0.1s, the mark point mark cannot be displayed, and the mark points of the two scales are easy to stagger and disorder.
Step 12: the method comprises the steps that a sending terminal device collects currently played audio and video source information and playing progress graduated scale attributes and sends the information and the attributes to a receiving terminal device, wherein the source information is a current audio and video address of the sending device, and the playing progress graduated scale attributes are the total length of the audio and video and mark point positions;
the sending end device collects source information of playing the audio and video through a collector, the source information is a link address of the source information, the link address is generally a same resource identifier (URI) address, for example, the link address may be a same resource locator (URL) address or a same resource name (URN), and the invention is not limited to this.
And while transmitting audio and video source information, the transmitting terminal equipment also packs and transmits an attribute numerical value of the playing progress graduated scale, namely the total length of the audio and video and the positions of the mark points, wherein the attribute of the playing progress graduated scale is provided with a graduated scale identifier, the total length of the audio and video is marked by a length identifier L, and the mark points are marked by an identifier M.
Step 13: receiving end equipment receives the source information and the attribute of the playing progress scale, analyzes the source information and obtains an audio and video playing source corresponding to the source information according to an analysis result;
step 14: the receiving end equipment marks the graduated scale with the same attribute according to the attribute of the graduated scale of the playing progress, marks the time length and the mark points of the audio and video on the graduated scale with the same attribute when the receiving end equipment opens the audio and video corresponding to the source information, and calculates the current playing time point according to the mark points;
and after receiving the attribute analysis of the playing progress scale, the receiving end equipment obtains a specific attribute numerical value, loads the specific attribute numerical value into a first adjustment reference item of a scale table generated on the scale with the same attribute, identifies the corresponding total length parameter grid according to the length identifier L by the audio/video total length, and identifies the corresponding marking position parameter grid according to the identifier M by the marking point. And the receiving terminal equipment adjusts the playing position according to the scale table adjustment reference item, and simultaneously corresponds the total length and the playing position of the audio and video being played on the playing interface of the receiving terminal equipment to the scale description with the same attribute.
The positions of the mark points of the scale are described in scale units, for example, the mark point section has 30 scale units, the scale unit is 10s, and the playing time of the mark points is 300 s.
Step 15: the receiving end device starts playing from the current playing time point.
The playing progress is marked more intuitively and accurately through the graduated scale; compared with a comparison file, the playing synchronization of the sending terminal and the receiving terminal is better, and the real-time performance is stronger.
The sending end equipment and the receiving end equipment are both equipment which can surf the internet through a network protocol, and can be smart phones, tablets, computers, televisions and the like.
Fig. 2 shows a flow diagram of a second embodiment of the on-screen video playing method according to the embodiment of the present invention.
Step 16, the sending end equipment extracts the data of the graduated scale of the current playing progress according to a preset time interval, and sends the extracted data to the receiving end equipment;
in order to improve the synchronization precision, the preset time is not less than 1 min; and the sending end equipment adds the marker symbols to the position data of the current marking point of the playing progress graduated scale according to the preset time interval and then sends the data to the receiving end equipment.
Step 17, the receiving end equipment receives the data of the graduated scale of the current playing progress sent by the sending end equipment at any time, compares the marking point position of the graduated scale of the current playing progress with the marking point position of the graduated scale of the same attribute, and regenerates a new marking point of the graduated scale of the same attribute according to the marking point of the graduated scale of the current playing progress when the marking point positions of the graduated scale of the same attribute exceed the preset difference value;
the receiving end equipment analyzes the scale size data of the received playing progress, updates a second adjustment reference item in a scale table corresponding to the identifier of each attribute value after analysis, compares the updated data with the attribute data of the same attribute scale, compares the difference data of the mark points of the two scales with a preset difference value, and if the preset difference value is two scale units, exceeds the preset difference value when the difference value of the two mark points is more than 2; and the receiving terminal equipment adjusts the currently played mark point according to the mark point value of the playing progress scale, namely, a new mark point is generated, and the audio and video playing point is adjusted by the new mark point.
Step 18, the attributes of the playing progress graduated scale and the attributes of the graduated scale with the same attributes further comprise the moving speed of the mark points on the playing progress graduated scale; after the attribute of the playing progress graduated scale is received by the receiving terminal equipment, the attribute of the playing progress graduated scale is compared with the movement rate of the mark point of the graduated scale with the same attribute, and when the movement rates of the attribute of the playing progress graduated scale and the mark point of the graduated scale with the same attribute are different, the movement rate of the mark point of the graduated scale with the same attribute is adjusted to be consistent with the movement rate of the mark point of the playing progress graduated scale.
In the process of playing audio and video on the same screen, when the sending end equipment carries out playing operation commands such as fast forward, slow forward, fast backward or slow backward, the receiving end cannot synchronously operate.
Specifically, after analyzing the received playing progress scale size data, the receiving end device also obtains the mark point moving speed of the playing progress scale, describes the mark point moving speed corresponding to the mark point in the scale table, compares the mark point moving speed with the mark point moving speed of the scale with the same attribute, and compares the two mark point moving speeds. When the two numerical values are different, if the speed of the playing progress graduated scale is v1, and the speed of the graduated scale with the same attribute is v2, v1 is not equal to v 2; and the receiving end equipment adjusts the mark point moving speed of the currently played mark point according to the mark point moving speed of the playing progress scale. In advance, the mark point moving speed needs to be set to correspond to the fast forward, slow forward, fast backward or slow backward playing operation commands, for example, the mark point moving speed v1 is 2, and the mark point moving speed v2 is 1, which means that the mark point is fast forward by one time.
