Example 1
Fig. 1 is a schematic flow chart of the method for performing blocked fly-screen playing on data in this embodiment. In this embodiment, the number of decoders at the receiving end of the fly-screen data is obtained, and the fly-screen data is segmented into segments of a corresponding number according to the number of decoders, and the segments are transmitted to the decoders through the fly-screen for decoding and playing. The method for playing data in a blocked fly screen mode in this embodiment includes the following steps:
step 101, setting the number of idle decoders on a receiving device of the fly screen data on a transmitting device of the fly screen data, and segmenting the fly screen data into corresponding number of fly screen data fragments.
Preferably, the decoder is a CPU. The method comprises the steps of capturing the screen flying data on sending equipment through a screen flying technology, for example, capturing game picture data on a PC, automatically segmenting the screen flying data, transmitting the screen flying data segment to receiving equipment (such as a television) for decoding and then playing, and enabling a user to obtain better watching experience. However, the number and performance of decoders of the receiving device are different, and if a poor decoder on the receiving device is used for decoding and playing the fly screen data, the decoding and playing efficiency is low.
In the step, the flying screen data fragments are transmitted to the receiving equipment for parallel decoding and playing according to the number of the decoders on the receiving equipment on the sending equipment, so that the efficiency of decoding and playing the flying screen data is improved. In particular, the efficiency of decoding and playing the fly-screen data can be improved under the condition that the performance of a decoder on a receiving device is poor.
And 102, receiving a flying screen playing instruction of a user by the receiving equipment, searching all sending equipment in the same local area network, connecting to corresponding sending equipment according to the selection of the user, and sending a flying screen playing request, wherein the request contains the number information of idle decoders in the receiving equipment.
And 103, the sending equipment receives the flying screen playing request, acquires the flying screen data requested to be played from the local according to the flying screen playing request, and searches and connects to the receiving equipment.
And the user can control the transmission of the flying screen data on the transmitting equipment to the receiving equipment for decoding and playing through the flying screen playing request. Preferably, the information such as an identifier of the flight screen data requested to be played, a storage location, and an identifier of a receiving device desiring to play the flight screen data is carried in the flight screen playing request. The sending equipment can find and acquire the fly-screen data through the identification and the storage position of the fly-screen data; and the sending device can also search the receiving device based on the same network (such as a local area network) or a wireless communication network such as bluetooth according to the identification of the receiving device which wants to play the fly screen data.
The sending equipment is connected to the receiving equipment, and the receiving equipment acquires the number of current idle decoders according to the flying screen playing request and sends the number of idle decoders to the sending equipment through the flying screen playing request. Preferably, the receiving device uses a decoder reading function to obtain the number of decoders on the receiving device, and then determines the number of decoders idle on the receiving device by whether to operate or not.
And 104, the sending device receives the number of idle decoders from the receiving device, segments the flying screen data into flying screen data fragments with corresponding number according to the number of the idle decoders, and distributes the flying screen data fragments to the idle decoders.
And on the sending equipment, cutting the fly screen data to be transmitted into the fly screen data blocks with the same number as the idle decoders on the receiving equipment, then decoding the fly screen data blocks on the receiving equipment by using the decoders, combining the decoded fly screen data blocks, and rendering the combined fly screen data blocks to an interface for playing.
And 105, receiving the flying screen data fragments by the idle decoder for decoding, combining the decoded flying screen data fragments according to the time stamp sequence, and rendering and playing.
In the step, all idle decoders on the receiving device are fully utilized to decode the flight data fragments in parallel, the advantages of the multiple decoders of the receiving device are fully exerted, the decoding performance of the flight data fragments can be improved, and therefore the receiving device with poor decoding performance can decode and play large high-definition data.
Fig. 2 is a schematic diagram illustrating transmission of data between a sending device and a receiving device in the method for performing blocked fly-screen playing on data according to this embodiment. In fig. 2, a sending device 201 receives a fly-screen playing request sent by the receiving device 202, the receiving device 202 obtains the number of idle decoders 221 according to the fly-screen playing request and feeds back the number to the sending device 201, and the sending device 201 divides the fly-screen data into to-be-played fly-screen data fragments according to the number of idle decoders 221 and distributes the to-be-played fly-screen data fragments to the idle decoders 221 for decoding.
According to the method for performing block-based fly-screen playing on data, the fly-screen data is transmitted to the fly-screen data receiving terminal in a block-based manner for decoding and rendering playing, so that hardware resources of the fly-screen data receiving terminal are fully utilized, and meanwhile, the fly-screen data playing efficiency is improved.
Example 2
Fig. 3 is a schematic flow chart of the method for performing blocked fly-screen playing on data according to this embodiment. This embodiment describes, on the basis of embodiment 1, specific contents of performing, on a transmitting device of the femto data, femto data slicing according to the number of idle decoders on a receiving device of the femto data. The method for playing data in a blocked fly screen mode in this embodiment includes the following steps:
step 301, on a receiving device of the fly-screen data, searching and connecting to the sending device according to an instruction of a user, acquiring the number of decoders on the receiving device, detecting and judging the number of current idle decoders, generating a fly-screen playing request, and sending the fly-screen playing request to the sending device.
And step 302, the sending device obtains the fly screen data requested to be played from the local according to the fly screen playing request.
Step 303, the sending device sets pre-splitting points for uniform splitting on the fly screen data according to the number of the idle decoders. And judging whether the precut point is a key frame or not.
Preferably, in this step, pre-cut points are set in a number that is a predetermined multiple of the number of idle decoders. More preferably, the predetermined multiple is 1-5. Some high definition data files are large, for example, 3D video files, only the flying screen data are sliced according to the number of idle decoders on the receiving device, which may cause that the sliced flying screen data slice files are still large, which is not favorable for transmission among the flying screen devices, and may also affect the decoding efficiency. The setting in this step is favorable to promoting the decoding and playing efficiency on the receiving device to divide the fly screen data into smaller fly screen data fragments.
And 304, when the pre-segmentation point is a key frame, the sending device segments the flying screen data into flying screen data segments from the pre-segmentation point, sequentially numbers the flying screen data segments, and distributes the flying screen data segments to the idle decoder.
Step 305, when the pre-cut point is not a key frame, the sending device sets the nearest key frame position before or after the pre-cut point as a cut point, cuts the fly screen data into fly screen data slices from the cut point and numbers the fly screen data slices in sequence, and distributes the fly screen data slices to the idle decoder.
In this step, the screen data is segmented according to the key frames, so that the segmented screen data fragments are data fragments which can be played independently, and the screen data fragments can be played after the screen data fragments are rendered while the screen data fragments are decoded on the receiving device. In addition, in the step, the screen data is segmented into the screen data segments at the key frame position closest to the pre-segmentation point, so that no screen data is lost in the process of segmenting the screen data.
And step 306, in the receiving of the receiving device, the idle decoder receives and decodes the flying screen data fragments, and obtains the decoded flying screen data fragments according to the numbering sequence for rendering and playing.
In this embodiment, based on the hardware characteristics of the receiving terminal of the fly-screen data, the fly-screen data is blocked according to the key frame and the fly-screen data fragments are transmitted, so that each fly-screen data fragment can be played independently, the scheme that the blocking is performed while the decoding is performed on the receiving device, or the fly-screen data fragment is selected to be played can be realized, and the viewing experience of the user is further improved.

Step 402, the computer obtains the requested screen data from the local according to the screen playing request.
Step 403, the computer sets pre-cut points for uniform segmentation on the fly screen data according to the number of the idle decoders, and judges whether the pre-cut points are key frames.
And 404, when the pre-segmentation point is judged to be the key frame, the computer segments the fly screen data into fly screen data segments from the pre-segmentation point, sequentially numbers the fly screen data segments, and distributes the fly screen data segments to the idle decoder.
Step 405, when the pre-cut point is judged not to be a key frame, the computer acquires that the nearest key frame position before or after the pre-cut point is a cut point, cuts the fly screen data into fly screen data fragments from the cut point and sequentially numbers the fly screen data fragments, and distributes the fly screen data fragments to the idle decoder.
And 406, in the TV box, the idle decoder receives the flight data fragments and decodes the flight data fragments, and the TV box obtains the decoded flight data fragments according to the serial number sequence and renders the flight data fragments to a television interface for playing.
