Detailed Description
Various embodiments are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that such embodiment(s) may be practiced without these specific details.
FIG. 1 shows an architectural schematic of a control system according to one embodiment of the invention. As shown in fig. 1, the control system 10 may include an electronic device 20, a main unit 30, a route information server 40, and a content server 50. The electronic device 20 may communicate with the main unit 30 via a short-range wireless communication technology (e.g., Wireless Local Area Network (WLAN) technology, bluetooth communication technology, WiFi, or the like). The main unit 30 may communicate with the route information server 40 and the content server 50 via mobile communication technology.
The electronic device 20 may be a smartphone, a tablet computer, a notebook computer, or the like.
The main unit 30 is located in the vehicle TT and has a navigation function. For example, the main unit 30 may be a navigation device mounted in the vehicle TT.
The route information server 40 collects and stores information about each of the respective links within the road network, wherein the information may include the length of each of the respective links within the road network, the vehicle travel speed, the allowable data transfer rate, and the road grade. The vehicle travel speed of each link L1 may indicate the average vehicle speed at which the vehicle is traveling over link L1. The allowed data transmission rate of the link L1 indicates the maximum data transmission rate that the mobile communication system can provide within the range of the link L1. The road grade of the link L1 may be an expressway, a second-level highway, a third-level highway, etc., wherein the road condition will deteriorate when the road grade of the link changes from the expressway to the third-level highway. The vehicle travel speed and the allowable data transfer rate for each of the various links within the road network may be obtained in any suitable manner. For example, roadside devices may be placed in the road network to detect the vehicle travel speed of a vehicle. The vehicle travel speed may be an average of collected vehicle travel speeds of vehicles traveling on each of the respective links within the road network. The roadside apparatus may also acquire the allowable data transmission rate by detecting the maximum data transmission rate that the mobile communication system can provide within the range of each of the individual links within the road network. Furthermore, the allowed data transmission rate may also be obtained from the operator of the mobile communication network system.
Fig. 2A and 2B show a flow chart of a control method according to an embodiment of the invention. In this embodiment, the user U1 with the electronic device 20 is seated in the vehicle TT and is ready to travel via the vehicle TT to the destination D1.
As shown in fig. 2A and 2B, at step S202, the electronic device 20 may establish a connection with the main unit 30 of the vehicle TT by any wired or wireless communication technique.
In step S208, in response to the request from the master unit 30, the route information server 40 generates a route RT from the start point D2 to the destination D1, where the start point D2 and the destination D1 are received by the route information server 40 from the master unit 30. How to generate a route from a starting point to a destination is known to those skilled in the art, and thus a description of generating a route from a starting point to a destination is omitted herein.
At step S212, the route information server 40 generates route information RI based on the stored information about each of the respective links within the road network. The route information RI indicates the required vehicle travel time and the allowed data transfer rate for the route RT. The route information RI may include, among others, the length of each of the individual links constituting the route RT, the vehicle running speed, the allowable data transfer rate, and the road class.
In step S214, the route information server 40 transmits the route RT and the route information RI to the main unit 30 of the vehicle TT.
In step S218, the main unit 30 of the vehicle TT transmits the route information RI to the electronic device 20.
In step S220, the electronic device 20 stores the route information RI received from the main unit 30 of the vehicle TT.
When the user U1 wants to watch a video in the vehicle TT, the electronic device 20 transmits a video playback request including the route information RI and information on the maximum buffer size of the electronic device 20 to the content server 50 via the main unit 30 of the vehicle TT at step S222.
At step S224, based on the route information RI included in the video playback request, the content server 50 produces a video name list in which all video contents of videos corresponding to each video name in the video name list can be transmitted to the electronic device 20 and played back by the electronic device 20 before the vehicle TT reaches the destination D1 of the route RT.
For example, the content server 50 may calculate a required vehicle travel time for each of the respective links constituting the route RT based on the length and the vehicle travel speed of each of the respective links constituting the route RT, calculate a sum of the required vehicle travel times for each of the respective links constituting the route RT as the required vehicle travel time for the route RT, calculate a downloadable data amount for each of the respective links constituting the route RT by multiplying the required vehicle travel time for each of the respective links by an allowable data transfer rate for each of the respective links, and calculate a sum of the downloadable data amounts for each of the respective links constituting the route RT as the maximum downloadable data amount for the route RT. The content server 50 searches videos stored in the content server 50 for a required vehicle travel time whose duration is less than or equal to the route RT and a video whose data amount is less than or equal to the maximum downloadable data amount of the route RT, and forms the video name list using the names of the searched videos.
In step S226, the content server 50 transmits the video name list to the electronic device 20 via the main unit 30 of the vehicle TT.
In step S228, the electronic device 20 presents the list of video names from the content server 50 for the user U1 to select the video that the user U1 wants to view.
In step S230, the electronic device 20 transmits the video name VN corresponding to the video PV selected by the user U1 to the content server 50.
In step S232, the content server 50 determines the data transfer policy of the video PV corresponding to the video name VN based on the road level of each of the individual links constituting the route RT, the required vehicle travel time and the allowed data transfer rate, the video bit rate of the video PV, and the maximum cache size of the electronic device 20. The data transfer policy of the video PV indicates an actual data transfer rate at each time t at which the video PV is transmitted, which is less than or equal to an allowable data transfer rate at the time t. The data transfer strategy of the video PV will be such that not only all of the video content of the video PV can be sent to and played by the electronic device 20 before the vehicle TT reaches the destination D1 of the route RT, but the total amount of video content sent of the video PV at any time is less than or equal to the sum of the maximum buffer size of the electronic device 20 and the total amount of video content played of the video PV at that time.
For example, the data transfer policy of the video PV may be determined by using the following equation (1).
Where T is a required vehicle travel time of the route RT, which is the sum of the required vehicle travel times of each of the individual links constituting the route RT. I (t) is the data transfer strategy of the video PV. S (t) is a play switch function, which is 0 or 1, where s (t) is determined based on the required vehicle travel time and road level for each of the various links making up the route RT, that is, s (t) is 0 when the vehicle TT is traveling on a certain link of the route RT at time t, the road level of which indicates that the road condition of the certain link will affect the video viewing experience (e.g., the certain link is a bumpy road, etc.), and s (t) is 1 when the road condition of the certain link does not affect the video viewing experience. R (t) is the video bit rate of the video PV. B (t) is the total amount of video content in the video PV that has been sent to the electronic device 20 but has not yet been played by the electronic device 20, and b (t) is less than or equal to the maximum buffer size of the electronic device 20.
In step S234, the content server 50 transmits the video content of the video PV to the electronic device 20 via the main unit 30 of the vehicle TT based on the data transfer policy of the video PV.
In step S236, the electronic device 20 buffers the received video content of the video PV, that is, stores the received video content of the video PV in the buffer of the electronic device 20.
In step S238, the electronic device 20 plays the video content of the video PV stored in the cache of the electronic device 20.
In step S240, the main unit 30 of the vehicle TT constantly acquires the current position of the vehicle TT at predetermined time intervals.
In step S242, the master unit 30 of the vehicle TT transmits the acquired current position of the vehicle TT to the routing information server 40.
In step S244, the main unit 30 of the vehicle TT detects whether the vehicle TT is traveling on the route RT based on the current position of the vehicle TT.
In step S246, if it is detected that the vehicle TT is not traveling on the route RT, the master unit 30 of the vehicle TT transmits the destination D1 and the acquired current position of the vehicle TT as the start point D22 to the route information server 40 to request a search for a new route from the start point D22 to the destination D1.
In step S248, the route information server 40 generates a new route RT2 from the start point D22 to the destination D1.
At step S250, the route information server 40 generates new route information RI2 of the new route RT2 using the same method as mentioned above, wherein the new route information RI2 includes the length of each of the individual links constituting the new route RT2, the vehicle travel speed, the allowable data transmission rate, and the road class.
In step S252, the route information server 40 transmits the new route RT2 and the new route information RI2 to the main unit 30 of the vehicle TT.
In step S256, the main unit 30 of the vehicle TT transmits the new route information RI2 to the electronic device 20.
In step S258, the electronic device 20 transmits the new route information RI2 to the content server 50 via the main unit 30 of the vehicle TT.
In step S260, the content server 50 determines whether the remaining video content of the video PV can be transmitted to the electronic apparatus 20 and played by the electronic apparatus 20 before the vehicle TT reaches the destination D1 of the new route RT2 based on the new route information RI 2. The remaining video content of the video PV is content of the video PV that has not been transmitted to the electronic device 20.
For example, the content server 50 may calculate the required vehicle travel time for each of the respective links constituting the new route RT2 based on the length of each of the respective links constituting the new route RT2 and the vehicle travel speed. The content server 50 calculates the sum of the required vehicle travel times for each of the individual links constituting the new route RT2 as the required vehicle travel time for the new route RT 2. The content server 50 calculates the downloadable data amount of each of the individual links constituting the new route RT2 by multiplying the required vehicle travel time of each of the individual links constituting the new route RT2 by the allowable data transfer rate of each of the individual links constituting the new route RT 2. The content server 50 calculates the sum of the downloadable data amount of each of the respective links constituting the new route RT2 as the maximum downloadable data amount of the new route RT 2. The content server 50 determines whether the total amount of the remaining video content of the video PV is not more than the maximum downloadable data amount of the new route RT2 and the duration of the remaining video content of the video PV is not more than the required vehicle travel time of the new route RT 2. If the determination is negative, it is determined that the remaining video content of the video PV cannot be transmitted to the electronic apparatus 20 and played by the electronic apparatus 20 until the vehicle TT reaches the destination D1 of the new route RT 2.
In step S262, if the determination is negative, the content server 50 generates a first new video name list in which all video contents of videos corresponding to each video name in the first new video name list can be transmitted to the electronic device 20 and played by the electronic device 20 before the vehicle TT reaches the destination D1 of the new route RT 2.
In step S264, the content server 50 transmits the first new video name list and a message indicating that the transmission and playback of the video PV cannot be completed until the vehicle TT reaches the destination D1 of the new route RT2 to the electronic device 20 via the master unit 30 of the vehicle TT.
In step S266, the electronic device 20 presents the received message.
In step S268, if the user U1 of the electronic device 20 does not intend to continue the video PV and wants to select a new video for viewing, the electronic device 20 may present the received first new video name list so that the user U1 can select a new video name corresponding to a new video he/she wants to view.
In step S270, the electronic device 20 transmits the new video name NN to the content server 50 via the master unit 30 of the vehicle TT.
In step S272, the content server 50 determines a new data transfer policy of the new video NV corresponding to the new video name NN. The determination of the new data transfer policy is similar to that described in step S232, so that a detailed description thereof is omitted.
In step S274, the content server 50 transmits the video content of the new video NV to the electronic device 20 via the main unit 30 of the vehicle TT based on the new data transfer strategy of the new video NV.
In step S276, the electronic device 20 buffers the received video content of the new video NV.
In step S278, the electronic device 20 plays the video content of the new video NV stored in the cache of the electronic device 20.
In step S280, the route information server 40 detects whether the vehicle running speed or the allowable data transmission rate of any one of the respective links constituting the route RT changes at predetermined intervals.
In step S282, if the detection is affirmative, the route information server 40 determines whether the vehicle TT has traveled the specific link PL through the route RT based on the current position of the vehicle TT.
In step S284, if the determination of step S282 is negative, the route information server 40 transmits the update information of the specific link PL of the route RT (i.e., the updated vehicle travel speed and/or the updated allowable data transfer rate of the specific link PL of the route RT) and the current position of the vehicle TT to the master unit 30 of the vehicle TT.
In step S286, the main unit 30 of the vehicle TT forwards the update information of the specific link PL of the route RT and the current position of the vehicle TT to the electronic apparatus 20.
At step S288, the electronic apparatus 20 transmits the update information of the specific link PL of the route RT and the current position of the vehicle TT to the content server 50 via the main unit 30 of the vehicle TT.
At step S290, the content server 50 determines whether the remaining video content of the video PV can be transmitted to the electronic apparatus 20 and played by the electronic apparatus 20 before the vehicle TT reaches the destination D1 of the route RT based on the update information of the specific link PL of the route RT, the route information RI, and the current position of the vehicle TT. Wherein the remaining video content of the video PV is the video content of the video PV that has not been transmitted to the electronic device 20. The judgment of step S290 is similar to that of step S260, and thus a detailed description thereof is omitted.
In step S292, if the determination in step S290 is negative, the content server 50 generates a second new video name list in which all video contents of videos corresponding to each video name in the second new video name list can be transmitted to the electronic device 20 and played by the electronic device 20 before the vehicle TT reaches the destination D1 of the route RT.
In step S294, the content server 50 transmits the second new video name list and a message indicating that the transmission and playback of the video PV cannot be completed until the vehicle TT reaches the destination D1 of the route RT to the electronic device 20 via the main unit 30 of the vehicle TT.
In step S296, the electronic device 20 presents the received message.
In step S298, if the user U1 of the electronic device 20 does not intend to continue the video PV and wants to select a new video for viewing, the electronic device 20 may present the received second new video name list so that the user U1 can select a new video name corresponding to a new video he/she wants to view.
In step S300, the electronic device 20 transmits the new video name NE to the content server 50 via the main unit 30 of the vehicle TT.
In step S302, the content server 50 determines a new data transmission policy of the new video NM corresponding to the new video name NE based on the road level, the required vehicle travel time, and the allowed data transfer rate of each of the respective non-traveled links of the route RT, the video bit rate of the route RT, and the maximum buffer size of the electronic device 20. The determination of the new data transfer policy is similar to that described in step S232, so that a detailed description thereof is omitted.
In step S304, the content server 50 transmits the video content of the new video NM to the electronic apparatus 20 via the main unit 30 of the vehicle TT based on the new data transfer policy of the new video NM.
In step S306, electronic device 20 stores the received video content of new video NM in the cache of electronic device 20.
In step S308, the electronic device 20 plays the video content of the new video NM stored in the cache of the electronic device 20.
At step S310, the main unit 30 of the vehicle TT constantly determines whether the link affects the user U1 to view video, for example, by detecting the degree of bumpiness of the link on which the vehicle TT is traveling via a sensor mounted in the vehicle TT, or by detecting whether the link is a bumpy road based on the road level of the link. The road grade of the link on which the vehicle TT is traveling can be obtained from the route information stored in the main unit 30 of the vehicle TT.
In step S312, if the determination of step S310 is affirmative, the main unit 30 of the vehicle TT transmits a notification of pausing the play video to avoid eye fatigue to the electronic device 20.
In step S314, the electronic device 20 presents the received notification to pause the playing video to avoid eye fatigue. When the user U1 sees the notification presented on the electronic device 20, the user U1 may cause the electronic device 20 to temporarily stop playing the video.
As can be seen from the above description, the user in the vehicle is provided with only the video whose all video contents can be transmitted to and played by the electronic device before the vehicle reaches the destination, and therefore the present embodiment enables the user to download and view the entire video before the vehicle reaches the destination.
