In the process of establishing the GSstreamer playing link, a plurality of operations such as loading plug-in units, distributing memory and the like are involved, so that a long time is consumed, the playing speed of media assets is slow, and the user experience is affected.

FIG. 7 illustrates a GSstreamer playback link switch fund view. As shown in fig. 7, each time the display device 200 acquires a media asset, a GStreamer playing link corresponding to the media asset needs to be established to play the media asset, when a user controls the process of switching the display device 200 to the next media asset through the control apparatus 100, the display device 200 needs to delete the GStreamer playing link corresponding to the previous media asset and re-establish the GStreamer playing link corresponding to the next media asset, so that, when the display device 200 switches the media asset each time, the process of re-establishing the GStreamer playing link corresponding to the media asset further affects the playing speed of the media asset and affects the user experience.

In order to solve the problem that the playing speed of the media asset is slow and the user experience is affected in the display device 200, the application discloses the display device 200 and the playing method of the media asset, which can accelerate the playing speed of the media asset and improve the user experience.

The display device 200 shown in the present application includes a display 260 and a controller 250 configured to perform a configuration flow of the display device 200 as shown in fig. 8.

The user may send a first control instruction for acquiring the first media asset to the display device 200 through the control apparatus 100, and when the display device 200 receives the first control instruction, acquire the current media asset type corresponding to the first media asset in response to the first control instruction.

In the process of data interaction, a user can control the display device 200 through the control apparatus 100; the control device 100 may communicate by a direct wireless connection or by a non-direct connection. That is, in some embodiments, the control apparatus 100 may communicate with the display device 200 through a direct connection manner of bluetooth, infrared, or the like. When the user transmits a first control instruction for acquiring a first asset to the display device 200 through the control apparatus 100, the control apparatus 100 may directly transmit the first control instruction data to the display device 200 through bluetooth or infrared rays.

In some embodiments, the control apparatus 100 may also access the same wireless network as the display device 200 through a wireless router to establish indirect connection communication with the display device 200 through the wireless network. When the control apparatus 100 transmits the first control instruction, the control apparatus 100 may transmit the first control instruction to the wireless router, and then forward the first control instruction to the display device 200 through the wireless router.

After receiving the first control instruction, the display device 200 may acquire the first media asset from the server 400, or may acquire the first media asset from external devices having a storage function, such as a usb disk, a mobile hard disk, etc., so as to further acquire the current media asset type corresponding to the first media asset.

The display device 200 may provide a broadcast receiving tv function, and may additionally provide an intelligent network tv function of a computer supporting function, including, but not limited to, a network tv, an intelligent tv, an Internet Protocol Tv (IPTV), etc. The display apparatus 200 may acquire the first asset in real time through broadcast reception.

The display device 200 may also be in data communication with the server 400 via a variety of communication means, such as a communication connection via a local area network (Local Area Network, LAN), wireless local area network (Wireless Local Area Network, WLAN) and other networks. The server 400 may provide various contents and interactions to the display device 200. By way of example, the display device 200 interacts with an electronic program guide (Electrical Program Guide, EPG) by sending and receiving information, receiving software program updates, or accessing a remotely stored digital media library. The server 400 may be one cluster or a plurality of clusters. One or more types of servers 400 may be included. Other web service content such as video on demand and advertising services are provided through the server 400. The display device 200 may also acquire media assets in real-time through data communication with the server 400.

After the display device 200 obtains the first media asset, a transport protocol corresponding to the first media asset can be obtained, where the transport protocol corresponding to the first media asset includes, but is not limited to, at least one of an HLS transport protocol, a DASH transport protocol, and an MSS transport protocol, and at the same time, the display device can also obtain a coding format corresponding to the first media asset, where the coding format corresponding to the first media asset includes, but is not limited to, at least one of AVC, HEVC, and other coding formats.

When the display device 200 acquires the first asset from the server 400, since the first asset is transmitted through a transmission protocol, the display device 200 needs to determine the current asset type of the first asset together with the transmission protocol corresponding to the first asset and the encoding format corresponding to the first asset. For example, the current asset type of the first asset may be a first asset type, the first asset type being an asset type of an HLS transport protocol including AVC coding format.

When the display device 200 obtains the first media asset from the external device, the display device 200 can determine the current media asset type corresponding to the first media asset according to the encoding format corresponding to the first media asset only because the first media asset does not need to be transmitted through the transmission protocol at this time. For example, the current asset type of the first asset may be a second asset type, the second asset type being an asset type comprising an HEVC encoding format.

The current media asset type in the embodiment of the present application further includes a third media asset type (i.e., a media asset type including AVC coding format), and a fourth media asset type (i.e., a media asset type including DASH transmission protocol of AVC coding format), among other media asset types.

After the display device 200 obtains the current media asset type corresponding to the first media asset, it needs to determine whether the current media asset type is the same as the preset media asset type, if the display device 200 determines that the current media asset type is the same as the preset media asset type, the display device 200 can play the first media asset through the preset media asset play link corresponding to the preset media asset type. For example, if the preset media asset type is the first media asset type, the preset media asset playing link corresponding to the preset media asset type is a playing link capable of playing the first media asset type, and if the current media asset type corresponding to the first media asset is the first media asset type, the first media asset may be played through the preset media asset playing link.

If the display device 200 determines that the current media asset type is different from the preset media asset type, the display device 200 establishes a corresponding current media asset playing link through the current media asset type to play the first media asset, and if the preset media asset type of the display device 200 is the first media asset type, the preset media asset playing link corresponding to the preset media asset type is a playable link of the first media asset type, and if the current media asset type corresponding to the first media asset is the second media asset type, the first media asset cannot be played through the preset media asset playing link, so that the display device 200 needs to establish a media asset playing link corresponding to the second media asset type according to the second media asset type to play the first media asset.

In the process of establishing the preset media asset link, the display device 200 does not randomly select the preset media asset type and then establishes the preset media asset link according to the preset media asset type, but determines the preset media asset type through the following embodiments.

In some embodiments, after the display device 200 is powered on, a second media asset is acquired, where the second media asset is a media asset that has been played in a preset period of time. For example, the preset period may be set to 10 days, and the display apparatus 200 may determine the second asset by traversing the asset play record within 10 days of the built-in player. It should be noted that, the preset period of time of the present application includes, but is not limited to, only 10 days, and may be set according to practical situations, and the display device 200 may set a larger value of the preset period of time to obtain more second assets, so as to determine user preference according to the second assets, thereby facilitating more accurate determination of the preset asset type.

Fig. 9 illustrates a schematic diagram of a media asset play record in a display device. As shown in fig. 9, the media asset play record acquired by the display apparatus 200 includes: soul first set, play duration: 45 minutes; and c, a second set of souls, and playing time length: 10 minutes; deer records the first set, and the playing time is 40 minutes; the first set of the first season of the garden is played for 30 minutes; the first and second sets of the garden are played for 10 minutes, and the third set of the garden is played for 2 minutes. The display apparatus 200 determines a second asset according to the asset play record including: qin first set, qin second set, lu first set, tangyuan first set. Each second media asset corresponds to a historical media asset type, wherein the historical media asset type is the same as the current media asset type in kind, and an exemplary first set of soul and a second set of soul correspond to the first media asset type; deer records that the first set corresponds to the second medium type; the first set of tangyuan first season and the second set of tangyuan first season correspond to the third media type.

It should be noted that, the media asset play record shown in fig. 9 is only used as an exemplary illustration, and the embodiment of the present application does not use the media asset name as a distinction between the historical media asset types, and for example, the first set of the soul may correspond to the first media asset type, and the second set of the soul may correspond to the second media asset type.

The display device 200 obtains the weight corresponding to each historical media asset type, and the method for determining the weight corresponding to each historical media asset type by the display device 200 is as follows: the display device 200 obtains a second number of at least one second media asset corresponding to each of the historical media asset types; if a continuous play record exists in the media play record of the second media corresponding to any historical media type, determining the preference number corresponding to the historical media type according to the continuous play record, and determining the sum of the second number corresponding to the historical media type and the preference number as a weight corresponding to the historical media type; the continuous play record is used for representing that the adjacent second media assets are records of the same historical media asset type; if the second media asset corresponding to any historical media asset type does not have continuous play records in the media asset play records, determining the second number corresponding to the historical media asset type as a weight corresponding to the historical media asset type.

Taking the media play record as shown in fig. 9 as an example, the display device 200 obtains a second number of second media assets corresponding to the first media asset type as 2 (i.e. a first collection of souls and a second collection of souls); the second quantity of the second media assets corresponding to the second media asset type is 1 (namely deer records the first set); the second number of second assets corresponding to the third asset type is 2 (i.e., first set of first season in tangyuan, second set of first season in tangyuan).

Because the second media asset corresponding to the first media asset type has a continuous play record, that is, the first set of soul and the second set of soul are continuously played, the preference number corresponding to the first set of soul and the second set of soul needs to be calculated; by way of example, if there is one continuous play record, the preference number is recorded as 0.1; the preference number increases by 0.1 for every increase in one continuous play record. Therefore, in the media asset playing record shown in fig. 9, the weight corresponding to the first media asset type is 2.1; the weight corresponding to the second media asset type is 1; the weight corresponding to the third media asset type is 2.1.

The display device 200 may create a hash table as described in fig. 10, wherein the first hash table includes: the system comprises a first hash key item and a weight item, wherein the first hash key item is used for recording a media asset type, and the weight item is used for recording a weight corresponding to the media asset type; the second hash table includes: the system comprises a second hash key item and a link index data item, wherein the second hash key item is used for recording the media asset type, and the link index data item is used for recording link index data corresponding to the media asset type. The display apparatus 200 determines the link index data recorded in the second Zhang Haxi table according to the weight recorded in the first hash table. The display device 200 can quickly establish a preset media link according to the link index data.

Because the first and third media asset types are both the maximum weights and the weights are equal, in some embodiments, the display device 200 randomly selects any one of the first and third media asset types to determine as the preset media asset type.

In some embodiments, when the maximum values corresponding to the weights of the historical media asset types are equal, the display device 200 further determines that the method of the preset media asset type is: the method comprises the steps of obtaining an obtaining path corresponding to each historical media asset type, wherein the obtaining path comprises the following steps: the first acquisition path is acquired from a server, or the second acquisition path is acquired from external equipment; determining the duty ratio of the historical media asset types corresponding to each acquisition path in all the historical media asset types; and determining a preset media asset type according to the duty ratio of each acquisition path. By way of example, the first asset type acquired by the display device 200 is a first asset type including a transmission protocol, and thus the acquisition path is a first acquisition path; the second media asset type acquired by the display apparatus 200 is a media asset type that does not include a transmission protocol, and thus, the acquisition path thereof is a second acquisition path; the third asset type acquired by the display apparatus 200 is the asset type that does not include the transmission protocol, and thus the acquisition path thereof is the second acquisition path. Thus, the first acquisition path has a 1/3 duty cycle; the second acquisition path has a duty cycle of 2/3; indicating that the user prefers to watch the media acquired from the external equipment; accordingly, the display apparatus 200 determines the third asset type corresponding to the second acquisition path as the preset asset type.

After determining the preset media asset type, the display device 200 establishes a preset media asset playing link according to the preset media asset type. For example, the display device 200 establishes a preset media playback link that can play the third media type. When the first media asset played by the display device 200 is of the third media asset type, the playing can be started directly according to the preset media asset playing link, so as to improve the playing speed.

When the current media asset type is different from the preset media asset type, as shown in fig. 11, the display device 200 may monitor the memory in real time to obtain the current memory residual capacity; if the current memory remaining capacity of the display device 200 is less than the preset threshold, closing the preset media playback link. For example, the preset threshold is set to be less than 100MB, and if the current memory remaining capacity of the display apparatus 200 is less than 100MB, the operation speed of the display apparatus 200 may be affected, and therefore, when the display apparatus 200 obtains that the current memory remaining capacity is 90MB from the memory, since the current memory remaining capacity is less than the preset threshold, the display apparatus 200 closes the preset media playback link to ensure that the first media can be played. After the user views the first media asset, the user will generally switch the first media asset to the next media asset, in order to increase the playing speed of the next media asset in the switching process, in some embodiments, when the playing of the first media asset is finished, the display device 200 starts a timer from the playing finishing time point of the first media asset to obtain the timing time, and sets a preset interval at the same time, so as to determine whether the user sends a second control instruction for obtaining the third media asset within the duration of the preset interval.

For example, the play end time point of the first media asset is 0:00; the preset interval is 50 seconds, then at 0:00-0:50, if the display device 200 receives the second control instruction sent by the user and used for acquiring the third media asset, the user is indicated to switch to the third media asset in the duration of the preset interval.

The first media asset may be played through a preset media asset playing link or played through a current media asset playing link, so that at least one media asset playing link exists in the display device 200 before the display device 200 is switched to the third media asset; if the first media asset is played through the preset media asset playing link, a preset media asset playing link exists in the display device 200; if the first media asset is played through the current media asset playing link, a preset media asset playing link and a current media asset playing link exist in the display device 200 under the condition that the memory capacity is sufficient.

In the embodiment of the present application, when the user switches to the third media asset within the duration of the preset interval, the display device 200 may multiplex the existing media asset playing link to increase the playing speed.

Fig. 12 illustrates a display device configuration flowchart. As shown in fig. 12, in the process of multiplexing an existing media playback link by the display apparatus 200, the display apparatus 200 acquires a candidate media type corresponding to the third media in response to the second control instruction. If the candidate media asset type is the same as the preset media asset type, playing a third media asset through a preset media asset playing link corresponding to the preset media asset type; and if the candidate media asset type is the same as the current media asset type, playing the third media asset through the current media asset playing link corresponding to the current media asset type.

For example, when the current media asset type corresponding to the first media asset is the first media asset type and the preset media asset type is the first media asset type, before the display device 200 switches to the third media asset, only the preset media asset link that can be used to play the first media asset type exists in the display device 200, and if the candidate media asset type corresponding to the third media asset is the first media asset type, the display device 200 can directly play the third media asset through the preset media asset play link when switching to the third media asset in the duration of the preset interval. If the candidate media asset type corresponding to the third media asset is the second media asset type, the display device 200 establishes a media asset playing link corresponding to the second media asset type to play the third media asset.

When the current media asset type corresponding to the first media asset is the first media asset type and the preset media asset type is the second media asset type, before switching to the third media asset, the display device 200 has a current media asset link available for playing the first media asset type and a preset media asset link available for playing the second media asset type in the display device 200, and if the candidate media asset type corresponding to the third media asset is the first media asset type or the second media asset type, the display device 200 can directly play the third media asset through the preset media asset play link or the current media asset play link when switching to the third media asset in the duration of the preset interval. If the candidate media asset type corresponding to the third media asset is the third media asset type, the display device 200 establishes a media asset playing link corresponding to the third media asset type to play the third media asset.

In some embodiments, the preset interval may be determined according to the following implementation. The manner in which the display apparatus 200 determines the preset section includes: the display device 200 obtains at least one play real time point and at least one play end time point corresponding to the at least one second media asset; each second media asset corresponds to a playing start time point and a playing end time point; storing the second media asset in the media asset play record according to the play start time point and the sequence from the near to the far of the play time; obtaining a difference value from a play end time point of a previous second media asset to a play start time point of a next second media asset according to the media asset play record; and determining a preset interval according to the difference value.

For example, the play start time point corresponding to the first and second media assets acquired by the display device 200 is: 0:00:15; the play end time point is: 0:40:15; the play start time point corresponding to the second media asset is: 0:40:55; the play end time point is 1:20:55; the play start time point corresponding to the third second media asset is: 1:21:35; the play end time point is: 2:21:35 … …; thus, the difference between the second asset and the first second asset is 40 seconds; the difference between the third second asset and the second asset is 40 seconds.

If the interval between the playing ending time point of the previous second media asset and the playing ending time point of the next second media asset is too long, the user is characterized as not continuously watching the media asset. Accordingly, the display apparatus 200 needs to determine the preset section only by the difference value within the difference threshold. By way of example, the difference threshold may be set at 60 seconds. The display device 200 obtains differences within a plurality of difference thresholds according to the media play record.

If the number of the obtained difference values is smaller than the first number, determining an average value of all the difference values as a preset interval; the first number is, for example, 20. Taking the first number of 5 as an example, the difference values are 45 seconds respectively; 40 seconds; 30 seconds; 40 seconds; 50 seconds; the preset interval is 41 seconds.

Screening extremum in at least one group of differences from the differences if the number of the obtained differences is larger than the first number; and determining the average value of the screened differences as a preset interval.

In some embodiments, the display device 200 continuously opens the preset media playback link when the current memory capacity is greater than the preset threshold, so as to ensure that the display device 200 has the preset media playback link for selection in the process of playing the media or switching the media.

In some embodiments, the preset media playback link in the display device 200 may be updated periodically, for example, by setting up the first preset media playback link as a start date, redefining the preset media type once within 30 days according to the manner shown in the foregoing embodiments, and setting up the corresponding preset media playback link according to the redetermined preset media type. It should be noted that, the period of time for updating the preset media playback link may be set according to practical situations, including but not limited to 30 days. According to the technical scheme, the display device provided by the embodiment can solve the problems that in the related technology, the media playing speed is low and the user experience is influenced, the media playing speed is accelerated, and the user experience is improved.

By adopting the embodiment, when the currently played media asset type can be played through the preset media asset playing link, the playing speed of the media asset can be accelerated, and the user experience is improved.
