Description

Multimedia playing device and playing method thereof

The present invention relates to a playback device and a method for playing the same, and more particularly to a multimedia playback device having an automatic reply function and a playback method thereof.

Set-top box (STB) is mainly used to convert TV signals, including cable TV, satellite TV, terrestrial TV broadcasting and Internet TV (IP/). DSL TV) and other types of TV signals. In the past, the set-top box only had a one-way analog video receiving function, which can provide functions such as channel selection, channel decoding or lock code. As people's needs increase and the services provided by system vendors diversify, the current set-top boxes are moving toward two-way interactive and digital multimedia network communication applications for new service content.

With the rapid development of technology, today's electronic products are becoming more and more complicated because of the lower and lower operating voltages, faster and faster, and smaller and lighter, resulting in electrostatic discharge (ESD). In the case of a set-top box for playing multimedia content, if an electrostatic discharge occurs during playback, the system may suddenly stop operating due to electrostatic discharge protection measures of the set-top box or other reasons. At this time, even if the user restarts the system, the user can only return to the initial startup screen or the system menu, and the user needs to manually set to return to the previous state to continue playing, thus greatly reducing the user experience.

The present invention provides a multimedia playing device and a playing method thereof, which can restart the playback state after the multimedia streaming file is not normally terminated, and return to the playing state before the abnormal termination, thereby improving the user experience.

The multimedia playing device of the present invention is used for playing a multimedia streaming file, which comprises a processing unit and a monitoring unit. The monitoring unit is coupled to the processing unit. The processing unit plays the multimedia stream file. The processing unit updates the set value every time a specific period is played while playing the multimedia stream file, the initial set value is greater than the preset threshold, and the current play information of the multimedia stream file is recorded. Each time the interval is specified, the monitoring unit subtracts the set value from the increase value, and determines whether the set value minus the increase value is equal to or less than a preset threshold. If yes, the processing unit is restarted to play the multimedia stream file according to the last recorded current playing information.

The multimedia playing method of the present invention is applicable to a multimedia playing device. The multimedia playback device includes a processing unit and a monitoring unit. The multimedia playing method includes the following steps. The multimedia stream file is played by the processing unit. When the multimedia stream file is played, the set value is updated by the processing unit every time a specific period is played, the initial setting value is greater than the preset threshold, and the current playing information of the multimedia stream file is recorded. Each time the interval is specified, the set value is subtracted from the increase value by the monitoring unit, and it is determined whether the set value minus the increase value is equal to or smaller than a preset threshold. If yes, the monitoring unit restarts the processing unit and plays the multimedia stream file according to the last recorded current playing information.

Based on the above, the multimedia playing device and the playing method thereof provide the current playing information when the multimedia streaming file is played every time interval. Therefore, when the processing unit is abnormally terminated due to, for example, an electrostatic discharge phenomenon or other reasons, the playback state can be automatically resumed after the restart to resume playing the multimedia stream file, thereby improving the user experience.

The above described features and advantages of the invention will be apparent from the following description.

1 is a block diagram of a multimedia playback device in accordance with an embodiment of the present invention. Referring to FIG. 1 , the multimedia playback device 100 is configured to play a multimedia stream file, including a non-volatile memory component 110 , a processing unit 130 , a monitoring unit 150 , and a connector 170 . In the present embodiment, the multimedia playback device 100 is, for example, a digital set-top box. In other embodiments, the multimedia playback device 100 can be a music player or a video player. The music player is, for example, a CD player, an MP3 player, or the like, and the video player is, for example, a DVD player, a Blu-ray player, a digital set-top box, or the like. In other words, the present invention does not limit the type of the multimedia playback device 100 or the type of multimedia that can be played.

The non-volatile memory component 110 includes a non-volatile memory such as a flash memory, and is connected to the multimedia playback device 100 in an external or direct coupling manner for recording the current playback information required by the multimedia playback method of the embodiment. In this embodiment, the non-volatile memory component 110 is, for example, an embedded multi-media card (eMMC), and is directly coupled to the substrate of the multimedia playback device 100. However, in other embodiments, the non-volatile memory component 110 can also be, for example, an SD card, an MMC card, a memory stick, or a CF card, and is connected to the slot of the multimedia playback device 100 in an external manner. In practice, the invention is not limited thereto. Based on its inherent characteristics, the data recorded in the non-volatile memory element 110 does not disappear due to power outage or other reasons.

The processing unit 130 is coupled to the non-volatile memory component 110 for performing a playback function of the multimedia playback device 100. If the previous operation of the processing unit 130 is abnormally terminated, after the startup, it can return to the playing state before the abnormal termination by the current playing information recorded in the non-volatile memory component 110 to continue playing. In this embodiment, the processing unit 130 is a central processing unit (CPU). However, in other embodiments, the processing unit 130 may also be, for example, a system-on-chip (SOC), an application processor, a media processor, a microprocessor, or the like. A digital signal processor or the like, the present invention does not limit the type of processing unit used in this implementation.

The monitoring unit 150 is coupled to the processing unit 130 for monitoring whether the processing unit 130 is operating normally, and restarting the processing unit 130 when the processing unit 130 is not operating normally. In this embodiment, the monitoring unit 150 is also coupled to the non-volatile memory component 110, and the monitoring unit 150 can determine whether to restart the processing unit 130 by using information recorded in the non-volatile memory component 110. In detail, if the processing unit 130 is down, the processing unit 130 does not read or write the non-volatile memory element 110, indicating that communication between the processing unit 130 and the non-volatile memory element 110 has been interrupted. At this time, the monitoring unit 150 needs to directly read and write the non-volatile memory component 110 to know whether the processing unit 130 is down from the information recorded in the non-volatile memory component 110. The monitoring of the processing unit 130 by the monitoring unit 150 is not limited to the above, and the application of the embodiment is not limited thereto. The monitoring unit 150 is implemented, for example, by a reset integrated circuit (reset IC). However, in other embodiments, the monitoring unit 150 can also be a central processing unit, a microprocessor, a microcontroller, a digital signal processing (DSP) chip, or a field programmable gate array. A programmable unit such as array, FPGA, or the like is implemented, and the present invention is not limited thereto.

The connector 170 is coupled to the processing unit 130. The processing unit 130 can obtain the data required for playing, such as multimedia files or streaming, by using the connector 170. In this embodiment, the connector 170 includes, for example, a connection conforming to various interface standards such as a USB interface standard, an HDMI interface standard, a memory stick (MS) interface standard, or a local area network (LAN) interface standard. Device. It should be noted that the present invention does not limit the number of connectors 170, and those skilled in the art have the ability to add or reduce various types of connectors to the multimedia playback device 100 as needed.

In this embodiment, the non-volatile memory component 110 is configured with at least a counting block, a termination determining block, and a spare block for recording a set value, terminating information, and current playback required for playing a multimedia stream file. News. When the multimedia playback device 100 is shipped or used for the first time, the set value may be, for example, preset to 0, and the termination information may be set to, for example, a normal termination state, and does not include any current playback information. In particular, when the multimedia playback device 100 of the embodiment of the present invention plays the multimedia streaming file by the processing unit 130, the current playback information of the played multimedia streaming file is overwritten every interval (for example, 1 minute). To the non-volatile memory element 110. In addition, in this embodiment, the current playing information includes, for example, information, link, volume, screen resolution, and playback process used by the multimedia playback device 100 for playing the multimedia stream file to restore the playback status, but The invention is not limited to this.

However, in other embodiments, the set values described above may also be recorded, for example, without using the non-volatile memory component 110. In other words, the set value may be recorded in other volatile or non-volatile memory components that are directly accessible to the processing unit 130 and the monitoring unit 150, separately recorded in the monitoring unit 150, or separately recorded in the processing. The unit 130 and the two volatile or non-volatile memory elements of the monitoring unit 150 are dynamically changed by the communication between the processing unit 130 and the monitoring unit 150, and the present invention is not limited thereto.

It is worth mentioning that the multimedia playback device 100 does not always successfully play the multimedia streaming file when the multimedia streaming file is played, and the operation is normally terminated. The processing unit 130 may be abnormal due to various reasons such as an electrostatic discharge phenomenon. The operation of the processing unit 130 is stopped. Therefore, the multimedia playback device 100 defines "unusual termination" in the process of playing the multimedia streaming file due to, for example, electrostatic discharge or the like, due to an unexpected termination of playback. Conversely, if the multimedia stream file is expected to be played or paused, it is defined as "normal termination". The monitoring unit 150 is used to monitor the processing unit 130 and reset or restart the processing unit 130 when it is not properly terminated. Therefore, the setting position and setting manner of the monitoring unit 150 in the multimedia playback apparatus 100 often require special attention. In the embodiment of FIG. 1, processing unit 130 is coupled to connector 170, for example. In order to reduce the possibility of the electrostatic discharge phenomenon occurring in the monitoring unit 150, it is often placed in a space far from the processing unit 130 and the connector 170. As another example, in some embodiments, the multimedia playback device 100 may be provided with a heat sink metal plate. Similarly, in order to reduce the possibility of the electrostatic discharge phenomenon occurring in the monitoring unit 150, the monitoring unit 150 is usually kept away from the heat dissipation metal plate as much as possible in order to prevent the monitoring unit 150 from losing the function of the monitoring processing unit 130 due to electrostatic discharge.

2A and 2B are flowcharts of a multimedia playing method according to an embodiment of the present invention. Referring to FIG. 2A and FIG. 2B simultaneously, the multimedia playing method of this embodiment is applicable to the multimedia playing device 100 in FIG. The detailed flow of the method of the present embodiment will be described below with reference to the components of the multimedia playback apparatus 100 of FIG.

In the present embodiment, the activation of the processing unit 130 may be, for example, in response to a user's operation of the multimedia playback device 100 or, for example, in response to a restart command from the monitoring unit 150. First, the operation flow of the processing unit 130 in the multimedia playing method of this embodiment will be described with reference to FIG. 2A.

After the processing unit 130 is started or restarted, in step S201, the processing unit 130 determines whether its previous operation is normally terminated. In this embodiment, the processing unit 130 determines whether the previous operation is normally terminated according to the termination information recorded in the termination determination block of the non-volatile memory element 110. When the multimedia playback device 100 is shipped or used for the first time, the termination information (Normal_ShutDown) is preset to a normal termination (Normal_ShutDown=True) state, and is recorded in the non-volatile memory component 110 as the multimedia playback device 100 operates. The setting of the termination information will also have a corresponding change. For example, if the processing unit 130 is not properly terminated during operation due to an electrostatic discharge phenomenon or other reasons when the multimedia stream file is played in the previous time, the processing unit 130 records the non-volatile when the processing unit 130 is restarted. The termination information in the memory element 110 will be set to a state of abnormal termination (Normal_ShutDown = False). On the other hand, if the processing unit 130 successfully plays the multimedia stream file after the previous operation, the termination information will be set to the normal termination state. The manner in which the termination information is changed correspondingly with the operation of the multimedia playback apparatus 100 will be described in detail in the following description.

If it is determined in step S201 that the previous operation of the processing unit 130 is normally terminated, then step S203 is reached. In step S203, the processing unit 130 plays the multimedia stream file according to the operation and setting of the multimedia playback device 100 by the user, and sets the termination information in the non-volatile memory element 110 when starting to play the multimedia stream file. Is not terminated properly (Normal_ShutDown = False). In this way, if the processing unit 130 has not finished playing the multimedia stream file or the termination of the termination information is abnormally terminated, then when the processing unit 130 is restarted, it can be judged from the termination information. The previous operation was not terminated properly. In this embodiment, the processing unit 130 performs a specific manner of playing the multimedia stream file according to the operation and setting of the multimedia playback device 100 by the user, and those skilled in the art can obtain sufficient teachings from the prior art. Let me repeat.

On the other hand, if it is determined in step S201 that the previous operation of the processing unit 130 is abnormally terminated, the process proceeds to step S205. In step S205, the processing unit 130 replies to the state of playing the multimedia streaming file according to the current playing information and continues to play the multimedia streaming file. In this embodiment, the current playback information of the multimedia stream file is recorded in the non-volatile memory element 110 in an overwritten manner. Therefore, the current playback information on which the processing unit 130 is based in step S205 will be the latest current playback information that was last recorded to the non-volatile memory component 110. In other words, in the present embodiment, the processing unit 130 can continue to play the same as the setting before the abnormal termination (for example, the sound size or the screen resolution, etc.) from the point of time when the previous operation is abnormally terminated. A multimedia streaming file.

It is worth mentioning that, regardless of whether the multimedia playback device 100 plays the multimedia stream file by using step S203 or step S205, the termination information is maintained to be abnormally terminated during the process of playing the multimedia stream file. As such, if the processing unit 130 experiences any abnormal termination during playback, the termination information recorded in the non-volatile memory component 110 will be reliably recorded as an abnormally terminated state.

When the processing unit 130 plays the multimedia stream file, the monitoring unit 150 determines whether the processing unit 130 is down and needs to be restarted to continue playing the multimedia stream file by the size of the set value. The initial set value is greater than the preset preset threshold. Therefore, in step S207, the processing unit 130 updates the set value every interval of a certain period to maintain the set value to be greater than a preset threshold, and overwrites the current play information for playing the multimedia stream file in the In the non-volatile memory element 110, the monitoring unit 150 subsequently subtracts an increment value from the set value every interval of the same period in step S210. In this way, the monitoring unit 150 can further determine whether the processing unit 130 fails to maintain the set value according to whether the set value of the decrementing value is equal to or less than the preset threshold value in step S210, and further subtracts The processing unit 130 is restarted when the set value of the increase value is equal to or less than the preset threshold. A number of examples will be described below in conjunction with FIG. 2B to describe in detail the method by which the monitoring unit 150 determines whether to restart the processing unit 130 by using a set value.

In one embodiment, the set value is, for example, recorded in the count block of the non-volatile memory element 110, and the set value is initialized to a value greater than the preset threshold before the multimedia stream file begins to play. It should be noted that, as long as the operation of initializing the set value is completed before the multimedia stream file is played after the processing unit 130 is started, the present invention does not limit the specific time and manner of initializing the set value.

In step S207, the processing unit 130 increases the set value (such as, but not limited to, 3) recorded in the non-volatile memory element 110 by an increasing period (for example, but not limited to, 1 minute). For example, but not limited to, 1), for example 3+1=4.

On the other hand, while the processing unit 130 plays the multimedia stream file, in step S210, the monitoring unit 150 subtracts the set value by the same frequency (for example, every minute) that the processing unit 130 increases the set value. The same increase value (for example, 1), for example 4-1=3. More specifically, the processing unit 130 of the multimedia playback device 100 of the present embodiment and the monitoring unit 150 respectively increase and decrease the set value by a certain amount of the increment value. In this case, in the case that the processing unit 130 continues to operate normally, after the set value is first increased by the processing unit 130, the increment value is also subtracted by the monitoring unit 150; the set value is subtracted from the monitored unit 150. After the value, the processing unit 130 is also added back to the increasing value, and the setting value is added and subtracted under normal conditions. Therefore, the set value will not continuously increase or decrease, but will remain within a stable range, for example, the set value is maintained at 3. Conversely, when the processing unit 130 is not operating normally, the set value monitored by the monitoring unit 150 will decrease with the period of the experience.

In detail, the set value of the embodiment is recorded in the non-volatile memory component 110. When the processing unit 130 is not operating normally or the operation has not been abnormally terminated, the set value is not increased, but at the same time, the monitoring unit 150 still subtracts the set value from the set value at the same frequency, and causes the set value to continue to decrease over the period of the experience. Therefore, in the present embodiment, after subtracting the set value from the set value, the monitoring unit 150 can further determine whether the set value minus the increase value is equal to or smaller than the preset threshold to monitor whether the processing unit 130 operates normally.

In another embodiment, the set values are, for example, simultaneously recorded in the processing unit 130 and the monitoring unit 150, and each is initialized to the same value greater than a preset threshold before the multimedia stream file begins to play.

In step S207, the processing unit 130 increases the set value in the processing unit 130 (hereinafter referred to as a first set value, such as, but not limited to, 3) by a specific period (for example, but not limited to, 1 minute). The increase value (for example, but not limited to, 1), for example, 3+1=4, and transmits the increased set value (for example, 4) to the monitoring unit 150 to update the set value recorded in the monitoring unit 150 (below) Called the second set value).

On the other hand, while the processing unit 130 plays the multimedia stream file, in step S210, the monitoring unit 150 sets the second setting at the same frequency (for example, every minute) that the processing unit 130 increases the first set value. The value is subtracted from the same increment value (eg, 1) and passed back to processing unit 130 to update the first set value, such as 4-1=3. In other words, in the embodiment, the first set value and the second set value respectively recorded in the processing unit 130 and the monitoring unit 150 are synchronously increased or decreased by the communication between the processing unit 130 and the monitoring unit 150.

In detail, the set values of the present embodiment are simultaneously recorded in the processing unit 130 and the monitoring unit 150 and are synchronously increased and decreased. When the processing unit 130 is not functioning properly or the operation has not terminated normally, the second set value in the monitoring unit 150 is not increased, but at the same time the monitoring unit 150 still subtracts the second set value from the boosted value at the same frequency, and The second set value is continuously decreased as the period of the experience. Therefore, in the embodiment, after the second set value is subtracted from the boosted value, the monitoring unit 150 can further determine whether the second set value is equal to or less than a preset threshold to monitor whether the processing unit 130 operates normally.

It is worth mentioning that, in the above embodiment, the processing unit 130 increases the setting 先 prior to step S207, and then the monitoring unit 150 reduces the setting 步骤 in step S210. However, the present invention is not limited to this order. In other embodiments, for example, the monitoring unit 150 first reduces the setting ( (eg, 3-1=2), and then the processing unit 130 increases the setting 値 (eg, 2+1=3). In other words, the processing unit 130 in FIG. 2A cooperates with the monitoring unit 150 in FIG. 2B to perform the multimedia playing method of the embodiment, but both of them increase and decrease the setting in a specific cycle, but there is no inevitable existence. relationship.

In still another embodiment, the set value is, for example, separately recorded in the monitoring unit 150, and the set value is initialized to a value greater than a preset threshold before the multimedia stream file begins to play.

In step S207, the processing unit 130 resets the set value in the monitoring unit 150 to an initial set value (for example, 10) every interval of a specific period (for example, but not limited to, 1 minute).

On the other hand, while the processing unit 130 plays the multimedia stream file, in step S210, the monitoring unit 150 updates the set value (for example, every minute) in the same manner as the processing unit 130, that is, subtracts an increase from the set value. Value (for example, 1), for example 10-1=9. As a result, in the case that the processing unit 130 is operating normally, the set value is continuously reset to a preset value to maintain it greater than a preset threshold. Conversely, when the processing unit 130 continues to operate abnormally, the monitoring unit 150 cannot be reset to a preset value, so that the monitored set value will decrease with the period of the experience.

Therefore, in the present embodiment, after subtracting the set value from the set value, the monitoring unit 150 can further determine whether the set value minus the increase value is equal to or smaller than the preset threshold to monitor whether the processing unit 130 operates normally. If the set value of the subtracted increase value is equal to or smaller than the preset threshold, it indicates that the processing unit 130 does not operate normally to reset the set value, and the processing unit 130 is restarted in step S218. For example, the processing unit 130 can be electrically connected to the monitoring unit 150 by using a pin. Although the processing unit 130 does not operate normally, the overall multimedia playback device 100 continues to be powered. Therefore, the monitoring unit 150 sends a reset signal to the processing unit 130, and the processing unit can be automatically restarted.

Similarly, in the above embodiment, the processing unit 130 resets the setting 为 to the initial 先 prior to step S207, and then the monitoring unit 150 decreases the setting 步骤 in step S210. However, the present invention is not limited to this order. In other embodiments, for example, the monitoring unit 150 first reduces the initialized setting (for example, 10-1=9), and then the processing unit 130 resets the setting 为 to the initial setting (for example, 10). In other words, the processing unit 130 in FIG. 2A cooperates with the monitoring unit 150 in FIG. 2B to perform the multimedia playing method of the embodiment, but both of them increase and decrease the setting in a specific cycle, but there is no inevitable existence. relationship.

With the method of each of the above examples, the monitoring unit 150 can determine whether to restart the processing unit 130 by determining whether the set value of the subtracted increase value is equal to or less than a preset threshold. It should be noted that in the above embodiments, the preset threshold is set to, for example, 0, but is not limited thereto. In other embodiments, those skilled in the art have the ability to set preset thresholds based on initial setpoints and increments as needed.

After the processing unit 130 sets the set value and overwrites the current playback information for playing the multimedia stream file in the non-volatile memory element 110, the processing unit 130 transmits the notification signal to the monitoring in step S209. The unit 150 is configured to notify the monitoring unit 150 whether the multimedia stream file has been played. In an embodiment, the notification signal may be, for example, a playback process of the multimedia stream file, but is not limited thereto. In another embodiment, the notification signal may also be, for example, binary information that informs the monitoring unit 150 whether the multimedia stream file has been played.

Next, if it is determined in step S210 that the set value is greater than the preset threshold, then step S212 is reached. In step S212, the monitoring unit 150 determines whether a notification signal is received. If the monitoring unit 150 receives the notification signal, it determines whether the multimedia stream file has been played according to the received notification signal in step S214. If the determination result is yes, the process proceeds to step S216. If one of the above steps S212 or S214 is negative, the process returns to step 210.

In this embodiment, if the monitoring unit 150 receives the notification signal from the processing unit 130, and the notification signal indicates that the processing unit 130 has finished playing the multimedia streaming file, it indicates that the multimedia streaming file has successfully completed playing, and the process The situation in which the processing unit 130 does not terminate normally does not occur. In step S216, the monitoring unit 150 sets the termination information recorded in the non-volatile memory element 110 to be normally terminated. As a result, when the processing unit 130 starts up next time, the termination information is maintained in a normally terminated state.

In addition, if the result of the determination in the above step S212 is no, it indicates that no notification signal is received in the period, indicating that the processing unit 130 has abnormal operation, but the set value has not been equal to or less than the preset threshold, and then returns. In step S210, the monitoring unit 150 waits for the operation of the next cycle. If the step S214 determines that the received notification signal indicates that the multimedia stream file has not been played, it indicates that the processing unit 130 is operating normally but the multimedia stream file has not been broadcasted. Similarly, the process returns to step S210, and the monitoring unit 150 waits for the next cycle. Actuate.

On the other hand, if the monitoring unit 150 determines in step S210 that the set value is equal to or less than the preset threshold, then the process proceeds to step S218 to restart the processing unit 130. In this embodiment, if the monitoring unit 150 determines that the set value is equal to or less than the preset threshold, it indicates that the processing unit 130 does not operate normally for a plurality of cycles, and therefore the processing unit 130 is restarted in step S218. Since the processing unit 130 suspends the restart before the multimedia stream file has been played, the processing unit 130 has abnormally terminated during the operation of playing the multimedia stream file. In the present embodiment, after the monitoring unit 150 issues the command to restart the processing unit 130, the processing unit 130 restarts and proceeds to step S201 again.

In this embodiment, after the processing unit 130 is restarted in response to the restart command of the foregoing monitoring unit 150, since the abnormal termination occurs in the previous operation, in step S205, the processing unit 130 is based on the record. The current playback information in the spare block of the volatile memory component 110 replies to the state of playing the multimedia streaming file and continues to play the multimedia streaming file. More specifically, since the current playback information in the non-volatile memory component 110 includes the current playback information last recorded to the non-volatile memory component 110 in the previous operation, the current playback information can be automatically The playback state is returned to the state before the previous processing unit 130 was abnormally terminated to continue playback.

In summary, the multimedia playback device and the playing method thereof according to the embodiments of the present invention can balance the set value by the processing unit and the monitoring unit, so that the function of monitoring the normal operation of the processing unit can be achieved at low cost. In addition, the embodiment of the present invention further records the current playing information when the multimedia streaming file is played in a specific period by using the non-volatile memory component. Therefore, when the processing unit is abnormally terminated due to, for example, an electrostatic discharge phenomenon or other reasons, after the restart, the playback state before the abnormal termination can be automatically resumed and the multimedia stream file is continuously played, thereby improving the user experience.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
