- the data transceiver 112 receives the interval data through the communication sockets
- the shared memory space 1110 is first received as shown in FIG. 15.
- the content data may be sequentially provided or fetched to the media processing unit 111 by a method of describing the order information 1122 on the section with respect to the moved section data.
- the amount of data unprocessed is the amount of data (or play time) remaining in the shared memory space 1110 that is not provided to the media processor 111 or that the media processor 111 does not read.
- FIG. 15 is a section in which the order of content data 1, 2, 3, 4, and 5, which are requested through communication sockets with the operating system 100a, are received in the order of 1, 3, 2, 4, and 5;
- the order is stored in the shared memory space in the receiving order
- the order information 1122 in the content data is stored in the memory map 1120 for storing each storage location address with the storage address 1121, the order According to the information 1122, the third stored section (Section 2) prior to the second stored section (Section 3) may be first drawn out or provided by the media processing unit 111 in order.
- the order information 1122 for data of each section stored in the shared memory space is a value for the order of sections identified from the information (request document identification information or order information) stored in association with each communication socket described above. This is recorded.
- indication information 1123 indicating that the interval data of the corresponding address is empty after being fetched or provided by the media processing unit 111 is appended to the data.
- the transceiver 112 allows the element to be used again.
- the indication information 1123 may not be used by adopting a circular buffer structure of the memory map 1120 by input and output pointers.
- the data transmitting and receiving unit 112 before the initial start-up or when there is a request for the transmission of new content, actively performing the selective use of the communication network illustrated in Fig. 7 or 8 (T61 or T62), or the Immediately before comparing the lower boundary value or the upper boundary value with the buffering amount, the lower boundary value and the upper boundary value are set or adjusted according to the current communication state, characteristics, or set conditions, which will be described in detail below.
- the data transmission / reception unit 112 sets the lower boundary value and the upper boundary value differently according to a mode for a communication network usage policy.
- the setting of these reference values is performed at the first startup of the data transmission / reception unit 112 or when there is a request for transmission of new content. If the mode is changed during execution, the reference values are changed and set accordingly.
- the mode for the communication network usage policy set in the communication terminal 100 will be described first.
- a data service for a cellular network generally uses a fee scheme in which a basic data amount is set for a basic fee and an additional cost is exceeded, and a free service is provided for a Wi-Fi network. Therefore, depending on the subscription plan, the user may incur additional fees in addition to the basic fee when the cellular network is continuously used in which the homeostasis of data service use is relatively sufficiently guaranteed.
- the embodiment according to the present invention provides modes for designating which network to select for a data service, with which aspects of the incurrence of the cost of the user's data service and the homeostasis of the data service use are more important factors. do. These modes include a "saving mode” for suppressing costs, a "convenience mode” for the convenience of the user, e.g., the homeostasis of data services, and a "standard mode” that compromises cost incurrence and user convenience.
- the media player 110 presents the illustrated modes through the user UI of the wireless communication terminal 100 when starting up or selecting new content, and selects one mode from a user and transmits and receives the data. The part 112 is notified.
- the data transmission / reception unit 112 sets the values 1220 for the lower threshold and the upper threshold as illustrated in FIG. 16 if the notified mode is the “standard mode”, and the notified mode is the “saving mode”. ”,
- the lower threshold and the upper threshold are the values of the corresponding reference value in the“ standard mode ”.
- Each value is set to smaller values 1221 as compared to the values 1220. If the lower threshold value is set to a smaller value, the requirement that the cellular network is used in combination with the Wi-Fi network alone (in the embodiment of FIG. 7 or the embodiment in which step S614 is excluded in FIG. 7) is used.
- the possibility of cellular network use is reduced compared to the standard mode, and setting the upper boundary value to a smaller value excludes the communication network in combination (the embodiment of FIG. 8 or step S632 or S633).
- the requirement for discontinuing the use of the cellular network and changing to the Wi-Fi network-only state becomes easier, so the possibility of the cellular network being shut down is higher than in the standard mode.
- the advertised mode is “convenient mode,” this means that the user thinks that the homeostasis of the data service is more important than the likelihood of cost, so as illustrated in FIG. 16, the lower threshold and upper threshold, Each value is set to higher values 1222 compared to the corresponding reference values in the "standard mode".
- the higher the lower threshold the greater the likelihood of using a cellular network with relatively higher homeostasis of service compared to the "standard mode", and the higher threshold being a higher value.
- the downside is that the likelihood of cellular network downtime is lower than in "standard mode”.
- the media player 110 may read a mode set by another application or process.
- FIG. 17 illustrates a related configuration according to the present embodiment.
- the illustrated mode determination unit 120 provides a user with a menu for mode determination at a specific time, for example, of the wireless communication terminal 100. It is provided when the screen lock is released or when a user executes a request and stores a mode set through the screen lock.
- the mode determination unit 120 presents at least a data usage status for the cellular network and the remaining days (or elapsed days) according to the plan period, so as to determine which mode is appropriate at the present time. You can also make it easier to judge.
- the stored mode value is shared by the data transceiving unit 112 by receiving and requesting the mode determining unit 120 when the media player 110 starts up. Acquiring a mode value from the mode determiner 120 (c131) may be performed through a channel established by the media player 110 by requesting an application or a process of a predetermined identification name from the operating system 100a. Can be.
- the mode determination unit 120 may also automatically determine a mode according to the data usage status for each communication network. To this end, the residual ratio rr is obtained as described above, and then the mode is automatically determined according to the value of the residual ratio rr. For example, when the residual ratio rr is less than 0.5, it may be determined as "saving mode", when more than 1.5, “convenience mode”, and when more than 0.5 and less than 1.5, "standard mode".
- the mode determination unit 120 may be integrally implemented as a sub-process of the media player 110 or may be implemented as a separate application.
- the wireless communication terminal 100 is automatically activated to determine one of the modes. As described above, the determined mode may be notified through a channel formed between processes through the operating system 100a.
- the mode determining unit 120 automatically determines a mode for a communication network usage policy
- the data transmitting and receiving unit 112 directly obtains the residual ratio rr.
- the request for the residual ratio rr obtained by the mode determination unit 120 is received and the value may be used to automatically determine whether to allow the cellular network as described above. .
- the data transmission and reception unit 112 if the current state using the Wi-Fi network (communication network usage state is "parallel", or the communication network usage state is used "alone" When the network is a Wi-Fi network), the amount of data received from the communication socket or communication sockets generated for the Wi-Fi network and moved to the receiving buffer 113a per reference time, that is, the monitored value for the reception speed is checked. If the monitored reception speed value (for example, the average reception speed value for a predetermined time) is larger than the designated appropriate speed, the lower threshold value and the upper threshold value are decreased according to the speed difference, and if the monitoring speed value is smaller, Increase.
- the monitored reception speed value for example, the average reception speed value for a predetermined time
- the lower boundary value and the upper boundary value which are decreased or increased may be values set according to the current mode.
- the higher the reception speed the less the possibility that the underrun (underrun) of the reception buffer 113a will occur. Therefore, the requirement to use a cellular network in combination with a Wi-Fi network alone is more stringent.
- the Wi-Fi network alone state will continue until the buffering amount is smaller than before the lower boundary value is adjusted.
- the upper boundary value is reduced in order to more easily reduce the requirement to change the use of the cellular network and to use the Wi-Fi network alone. Accordingly, even when the buffering amount is smaller than before the upper boundary is adjusted, the Wi-Fi network can be changed into a single use state.
- the upper boundary value may be adjusted according to a decreasing rate of the buffering amount of the receiving buffer 113a. For example, if the average deceleration rate for a certain time is faster than the specified speed by a certain allowance, the upper boundary value is increased, and if it is slow, the upper limit value is decreased. Also in this embodiment, the upper threshold value that is decreased or increased may be a value set according to the current mode.
- the current signal strength value for the connection point connected through the operating system 100a. is checked and compared with a previously determined value to determine its variation, and if the variation is greater than a predetermined limit, increase the lower and upper boundary values according to the difference.
- the lower threshold value and the upper threshold value increased at this time may be values set according to the current mode.
- Increasing the reference value may be due to the relative instability of the Wi-Fi network currently being used, for example, the movement of the wireless communication terminal 100 or the currently connected access point. The characteristics will be drastically deteriorated, so as to lead to the use of cellular networks as possible (in the embodiment of FIG. 7 or the embodiment of which step S614 is excluded from FIG. 7) or to maintain the combination of cellular networks (the embodiment or step S632 of FIG. 8). , In the case of the embodiment in which S633 is excluded).
- the change range of the monitored reception rate may be used instead of the change range of the signal strength value. That is, if the change rate of the current reception speed and the previously confirmed reception speed is larger than the predetermined limit, the lower threshold value and the upper threshold value are increased according to the difference. In this case, the lower threshold value and the upper threshold value that are increased may also be a value set according to the current mode.
- the data transmission / reception unit 112 adjusts the lower boundary value and the upper boundary value according to the remaining unreceived amount of the selected content.
- the lower threshold and the upper threshold adjusted at this time may also be values set according to the current mode.
- the data transmitting / receiving unit 112 identifies an unreceived residual amount from the total amount of current monitoring and the total size of the content data described in the previously stored metadata, and the residual amount is a predetermined threshold. If the value is 1401 or less (time t1), the lower boundary value and the upper boundary value are decreased according to the difference 1402. In this way, the use of the cellular network can be suppressed as much as possible when the remaining amount is small.
- the Wi-Fi network when the remaining amount determined as described above is less than or equal to the predetermined lower limit 1411 (time t2), the use of the cellular network may be stopped at that time.
- the threshold 1401 and the lower limit 1411 may be designated as the time of the reproduction viewpoint.
- the threshold 1401 may be designated as 30 seconds
- the lower limit 1411 may be designated as 10 seconds.
- the data transmission / reception unit 112 increases the lower boundary value and the upper boundary value when a transmission request for a specific area of the selected content is required.
- the lower threshold value and the upper threshold value increased at this time may also be values set according to the current mode.
- the specific zone may be identified by information described in metadata received and stored according to an initial content request, or by information that informs the specific zone in real time after transmission of the requested content by a server providing content. Can be identified.
- the zone description information for the specific zone for example, The zone indication information, the type of the zone, the bitrate required for the zone, and the like are included in the response to the request document requesting the divided section.
- the specific zone may be a section requiring increased bandwidth, or a section designated as a special section having high user preference for viewing, for example, a popular section or additional content (eg, advertising) provided by a content provider. It may be an insertion section of.
- the requesting section is identified by section description information previously identified by metadata or provided in real time. If it belongs to the lower boundary value and the upper boundary value is increased.
- the possibility of switching to coexistence is increased in the case of using the communication network alone, and the sustainability of the state is increased in the case of the coexistence, so the delay or request bit of the content data according to the reception of a specific section It is possible to prevent the reception phenomenon at a rate below the rate, to improve the reception reliability of the specific section, or to cope with the increase in the required bandwidth.
