Description
本發明是關於一種媒體播放系統及方法，特別是一種媒體播放節能系統及方法。 The invention relates to a media playing system and method, in particular to a media playing energy saving system and method.
現今，使用者除使用行動裝置播放媒體(音訊或影像)外，也常使用媒體播放裝置與行動裝置連線以播放媒體，藉以增加影音品質或達到影音與他人分享的效果，例如：使用者利用手機透過無線喇叭(wireless speaker)播放音樂。其中，若使用者經一段時間沒有在行動裝置輸入動作，行動裝置會進入閒置模式(idle mode)，閒置模式會產生關閉螢幕、關閉背光模組、降低處理器(CPU；Central Processing Unit)時脈或關閉閒置元件等方式以使行動裝置節能。 Nowadays, in addition to using mobile devices to play media (audio or video), users often use media playback devices to connect with mobile devices to play media, thereby increasing the quality of audio and video or achieving the effect of sharing audio and video with others. For example, users use The mobile phone plays music through a wireless speaker. If the user does not input the action in the mobile device for a period of time, the mobile device enters an idle mode, and the idle mode generates a shutdown screen, a backlight module, and a CPU (Central Processing Unit) clock. Or turn off idle components and other means to save energy in the mobile device.
惟然，行動裝置若在閒置模式下仍以串流(streaming)方式傳送媒體資料至媒體播放裝置以持續播放，例如：手機在此閒置模式下仍持續以音訊串流(audio streaming)方式傳送歌曲資料至無線喇叭播放音樂，根據量測數據顯示此時手機仍有最大約164mA的耗電流。由此可知，在行動裝置持續以串流方式透過媒體播放裝置進行媒體播放的情形下，對行動裝置的待機時間是不利的。尤其現今手機取向輕薄造型以增加攜帶性，對電池體積要求日益嚴苛，手機的待機時間長短亦是使用者購買時的重要參考因素。 However, if the mobile device still transmits the media data to the media playback device in a streaming mode for continuous playback in an idle mode, for example, the mobile phone continues to transmit the audio in an audio streaming mode in the idle mode. Data to the wireless speaker to play music, according to the measured data shows that the phone still has the most current consumption of about 164mA. From this, it can be seen that in the case where the mobile device continuously plays the media through the media playback device in a streaming manner, the standby time of the mobile device is disadvantageous. In particular, today's mobile phones are oriented in a thin and light shape to increase portability, and the battery size requirements are increasingly severe.

本發明的媒體播放節能系統1是透過節能函式11111及節能 韌體1221依照播放清單來播放媒體檔，進而實施節能播放模式。在此實施方式，媒體播放裝置12可為喇叭或視訊播放裝置，因此，要播放的媒體檔可以是音訊檔案或視訊檔案，如：MP3、WAV、APE、MP4等；行動裝置11可為智慧型手機；另外，媒體播放裝置12的暫存區121至少能容納播放清單中的單一個媒體檔。 The media playing energy-saving system 1 of the present invention transmits energy saving function 11111 and saves energy The firmware 1221 plays the media file according to the playlist, thereby implementing the energy-saving play mode. In this embodiment, the media playback device 12 can be a speaker or a video playback device. Therefore, the media file to be played can be an audio file or a video file, such as MP3, WAV, APE, MP4, etc.; the mobile device 11 can be intelligent. In addition, the temporary storage area 121 of the media playback device 12 can accommodate at least one single media file in the playlist.
一個播放清單中的各個媒體檔可以依次排列，並分成奇數 項次和偶數項次，於奇數項次播放期間，行動裝置11經通訊鏈結13傳送串流播放指令告知媒體播放裝置12，行動裝置11並對應產生第一、第二執行緒(Thread)。第一執行緒負責將奇數項次的媒體檔以串流模式傳送至媒體播放裝置12播放。第二執行緒負責將偶數項次的媒體檔以背景傳輸模式傳送至媒體播放裝置12的暫存區121，背景傳輸模式可為：檔案傳輸協定(FTP；File Transfer Protocol)或媒體傳輸協定(MTP；Media Transfer Protocol)。當第二執行緒執行完畢，且第一執行緒的串流模式亦執行完畢，行動裝置11傳輸暫存區播放指令，使媒體播放裝置12播放暫存區121的偶數項次媒體檔，同時，媒體播放裝置12回傳睡眠指令給行動裝置11使行動裝置11進入睡眠模式。一實施例中，在奇數項次的媒體檔播放期間進行量測，所得最大耗電流為196mA，與先前技術的音訊串流期間的最大耗電流164mA比較，多出32mA，此乃串流播放時一併進行背景傳輸模式及相關指令傳輸所造成的額外功耗。 Each media file in a playlist can be arranged in turn and divided into odd numbers. For the item and the even number, during the odd-numbered play, the mobile device 11 transmits a streaming play command to the media playback device 12 via the communication link 13, and the mobile device 11 generates the first and second threads (Thread) correspondingly. The first thread is responsible for transmitting the odd-numbered media files to the media playback device 12 in streaming mode. The second thread is responsible for transmitting the even-numbered media files to the temporary storage area 121 of the media playback device 12 in the background transmission mode. The background transmission mode may be: File Transfer Protocol (FTP) or Media Transfer Protocol (MTP). ;Media Transfer Protocol). After the execution of the second thread is completed, and the streaming mode of the first thread is also executed, the mobile device 11 transmits the temporary storage area playing command, so that the media playing device 12 plays the even-numbered media files of the temporary storage area 121, and The media playback device 12 returns a sleep command to the mobile device 11 to cause the mobile device 11 to enter a sleep mode. In one embodiment, the measurement is performed during the playback of the odd-numbered media files, and the maximum current consumption is 196 mA, which is 32 mA more than the maximum current consumption of 164 mA during the prior art audio stream, which is during streaming playback. The additional power consumption caused by the background transmission mode and related instruction transmission is also performed.
當偶數項次曲自暫存區121播放完畢，媒體播放裝置12發出 喚醒指令給行動裝置11以喚醒行動裝置11。接著，行動裝置11透過發出同步請求指令給媒體播放裝置12，使多媒體播放程式1111獲得媒體播放裝置12的媒體現今播放狀態，於是多媒體播放程式1111能在持續播放過程中同步更新媒體播放裝置12的媒體播放狀態。其中，當用戶主動喚醒行動裝置時(如：播/接電話、傳/收簡訊、按鈕或螢幕解鎖等動作)，同步請求指令及 狀態同步指令亦可被執行。一實施例中，在偶數項次曲播放期間進行量測，所得最大耗電流僅為3mA，與先前技術的音訊串流期間的最大耗電流164mA比較，大幅減少161mA，因此在長期播放狀態及媒體播放裝置12的暫存區121至少可容納一媒體檔的情形下，與先前技術相較，以播放兩首歌曲為例，偶數項次曲及偶數項次曲各一，假設兩首歌曲撥放時間相同(t/2)，則播放兩首歌曲所需時間總合為t，並納入前述奇數項次和偶數項次播放期間所量測耗電流資訊進行計算，估計節能百分比約可達1-{[(164+32)*(t/2)+3*(t/2)]/[164*(t/2)+164*(t/2)]}=39%。 When the even-numbered sub-curves are played from the temporary storage area 121, the media playback device 12 issues The wake-up command is given to the mobile device 11 to wake up the mobile device 11. Then, the mobile device 11 sends the synchronization request command to the media playback device 12, so that the multimedia player 1111 obtains the current playing state of the media of the media playback device 12, so that the multimedia player 1111 can synchronously update the media playback device 12 during the continuous playback. Media playback status. Wherein, when the user actively wakes up the mobile device (eg, broadcast/receive call, send/receive SMS, button or screen unlock, etc.), the synchronization request command and Status synchronization instructions can also be executed. In one embodiment, the measurement is performed during the even-numbered play, and the maximum current consumption is only 3 mA, which is significantly reduced by 161 mA compared with the maximum current consumption of 164 mA during the audio stream of the prior art. Therefore, in the long-term playback state and the media. In the case where the temporary storage area 121 of the playback device 12 can accommodate at least one media file, compared with the prior art, two songs are played as an example, and the even-numbered and the even-numbered songs are each one, assuming two songs are played. When the time is the same (t/2), the total time required to play two songs is t, and the current consumption information measured during the odd-numbered and even-numbered play is calculated. The estimated energy saving percentage is about 1- {[(164+32)*(t/2)+3*(t/2)]/[164*(t/2)+164*(t/2)]}=39%.
在上述實施方式中，為了清楚描述本發明有關節能函式 11111及節能韌體1221的操作方式，故簡易地設定媒體播放裝置12的暫存區121容量恰可容納單一媒體檔，及預設每次進行背景傳輸模式時，即傳輸單一媒體檔案至媒體播放裝置12的暫存區121，然其並非用以限定本發明。在其他的實施方式中，媒體播放裝置12的暫存區121容量可容納一個以上的媒體檔，進行背景傳輸模式時，同時參考暫存區121的現有容量、通訊鏈結13的頻寬及串流模式的媒體傳輸流量，傳輸最大容許值的媒體資料(可包含完整或部分的媒體檔)至媒體播放裝置12的暫存區121，可更進一步減少串流模式執行的時間，同時更能降低功耗；另外，在其他的實施方式中，奇數項次及偶數項次的媒體檔可以是切割自一個單獨的影音檔案的不同部分的媒體片段。 In the above embodiments, the energy saving function of the present invention is clearly described. 11111 and the operation mode of the energy-saving firmware 1221, so that the temporary storage area 121 of the media playback device 12 can be easily set to accommodate a single media file, and preset a single media file to media playback every time the background transmission mode is performed. The temporary storage area 121 of the device 12 is not intended to limit the invention. In other embodiments, the temporary storage area 121 of the media playback device 12 can accommodate more than one media file. When the background transmission mode is performed, the existing capacity of the temporary storage area 121, the bandwidth and the serialization of the communication link 13 are simultaneously referred to. The streaming mode media transmission traffic, the transmission of the maximum allowable media data (which may include a complete or partial media file) to the temporary storage area 121 of the media playback device 12, further reduces the execution time of the streaming mode, and at the same time reduces the time. Power consumption; in addition, in other embodiments, the odd-numbered and even-numbered media files may be media segments cut from different portions of a single video file.
