Description

多聲道音訊控制系統Multi-channel audio control system

本發明係有關於一種多聲道音訊控制系統，尤其是利用智慧無線遙控制器發射聲聲道控制指令以控制各聲道喇叭播放音訊內容，讓使用者依據實際需要及個人的偏好而指定喇叭的開關，進而擴大使用上的彈性。The present invention relates to a multi-channel audio control system, in particular, it uses a smart wireless remote controller to emit sound channel control commands to control the speakers of each channel to play audio content, allowing users to specify speakers according to actual needs and personal preferences Switch, and expand the flexibility of use.

隨著生活水準的提高，人們在追求休閒娛樂方面也越發注意品質的提升，而在視聽音響的休閒應用領域中，業者為實現高品質的聲音表現以滿足消費者的聽覺感官需求，已陸續推出數位化的立體聲、身歷聲、環繞音場的多聲道技術，比如杜比（Dolby）5.1聲道系統、7.1聲道系統或其他多聲道系統，並普遍用於電影院及音樂會場的播放。此外，在電子技術的不斷精進下，使得一般家庭也能在有限的花費下配置高品質的家庭電影院，因而在居家環境便能享受高檔音樂聽或電影院才有的音響品質。With the improvement of living standards, people are paying more and more attention to the improvement of quality in pursuit of leisure and entertainment. In the leisure application field of audio-visual audio, the industry has successively launched in order to achieve high-quality sound performance to meet the auditory and sensory needs of consumers. Digital stereo, stereo, and surround sound field multi-channel technology, such as Dolby 5.1 channel system, 7.1 channel system or other multi-channel systems, and is commonly used in movie theaters and concert venues. In addition, with the continuous advancement of electronic technology, ordinary families can also configure high-quality home theaters at a limited cost, so that they can enjoy high-end music listening or sound quality that can only be found in movie theaters at home.

在習用技術中，影音編碼訊號一般是來自DVD光碟、藍光播放機、線上影音來源等，具有固定的音軌及儲存格式，其中包含影像及多聲道音訊資料，在經過放大器主機的解碼、分離、放大後，將影像資料直接由顯示器播放，而多聲道音訊資料則由各個喇叭或音箱來播放，比如前置、側置及後置的不同喇叭，進而展現身歷其境的聽覺感受，讓聆聽者有如置身於現場實境一般。In the conventional technology, the video and audio coded signals generally come from DVD discs, Blu-ray players, online video and audio sources, etc., with fixed audio tracks and storage formats, including images and multi-channel audio data, which are decoded and separated by the amplifier host. , After zooming in, the image data is played directly by the monitor, while the multi-channel audio data is played by various speakers or speakers, such as different speakers on the front, side and rear, to show the immersive auditory experience. The listener is like being in the real world.

然而，上述習用技術的缺點在於不同音軌中的原始影音編碼訊號是經放大器主機的解碼後分離成給相對應喇叭播放的音訊資料，對於音訊格式為雙聲道立體聲的原始影音編碼訊號而言，即使播放的喇叭系統已升級成杜比7.1，也無法任意操控後置喇叭的音響功效，所以相當受限而沒有彈性。而且要拉喇叭線的佈線相當困難，而且原有的音軌受限，無法隨意選取喇叭撥放。However, the disadvantage of the above-mentioned conventional technology is that the original video and audio coded signals in different audio tracks are decoded by the amplifier host and then separated into audio data for the corresponding speakers. For the original video and audio coded signals whose audio format is two-channel stereo , Even if the speaker system is upgraded to Dolby 7.1, it cannot control the sound function of the rear speakers at will, so it is quite limited and inflexible. Moreover, it is quite difficult to pull the speaker cable wiring, and the original sound track is limited, and the speaker cannot be selected at will.

再者，就杜比7.1的一般喇叭實際配置而言，前置喇叭單元的喇叭是安置在使用者的前方，並靠近顯示器，中央聲道喇叭位於顯示器的下方，前置左聲道喇叭以及前置右聲道喇叭分別在顯示器的左側及右側，而後置左聲道喇叭及後置右聲道喇叭是位於使用者的二側或後方的二側，後置上方左聲道喇叭及後置上方右聲道喇叭是位於使用者的左後側及右後側的上方，超重低音聲道喇叭可能是較靠近使用者。因此，習用技術的杜比7.1實施方式需要大量的實體佈線以連接每個喇叭，造成整體環境的紊亂，而且還可能因為需要在天花板或牆面上鑽孔拉線，進而破壞原有的裝潢設計。Furthermore, in terms of the actual configuration of the general speaker of Dolby 7.1, the speaker of the front speaker unit is placed in front of the user and close to the display, the center channel speaker is located under the display, the front left channel speaker and the front The right channel speakers are located on the left and right sides of the display, while the rear left channel speakers and the rear right channel speakers are located on the user's side or the rear side. The rear left channel speakers and the rear top speakers The right channel speaker is located above the user's rear left and right sides, and the subwoofer channel speaker may be closer to the user. Therefore, the conventional Dolby 7.1 implementation requires a large amount of physical wiring to connect each speaker, causing chaos in the overall environment, and may also damage the original decoration design due to the need to drill cables on the ceiling or wall .

因此，很需要一種創新的多聲道音訊控制系統，利用智慧無線遙控制器發射聲道控制指令以改變不同喇叭的播音內容，讓使用者依據實際需要及個人的偏好而任意變更音響的效應，進而擴大使用上的彈性，尤其是由後置音訊處理單元依據聲道控制指令對音訊編碼訊號進行音訊解碼處理，產生完整音訊播放訊號，並由後置喇叭單元播放，藉以解決上述習用技術的問題。Therefore, there is a great need for an innovative multi-channel audio control system that uses smart wireless remote controllers to transmit channel control commands to change the broadcast content of different speakers, allowing users to arbitrarily change the sound effects according to actual needs and personal preferences. Further expand the flexibility of use, especially the audio decoding processing of the audio coded signal by the rear audio processing unit according to the channel control command to generate a complete audio playback signal, which is played by the rear speaker unit, thereby solving the above-mentioned conventional technology problems .

Corresponding channel audio in.

舉例而言，如果是雙聲道音訊輸入，使用者只能選擇 「2 CHANNELS」，同時「2 CHANNELS」的燈號會亮起，接著，可以任意選擇喇叭圖示，比如可以都不選、部分選或是全部都選，使得雙聲道音樂可依所選取的喇叭來播放。例如，在夜深人靜的時候看電視時，使用者可選擇靠近沙發的左後聲道喇叭RL、右後聲道喇叭RR來發聲，比較不會吵到家人，但如果是宴會的時候，則可以選擇後置上方左聲道喇叭ATL以及後置上方右聲道喇叭ATR播放天空聲道來當背景音樂，卻不會干擾到宴會談話。For example, if it is a two-channel audio input, the user can only select "2 CHANNELS", and the light of "2 CHANNELS" will be on. Then, the speaker icon can be selected arbitrarily, such as none, partial Select or select all, so that two-channel music can be played on the selected speakers. For example, when watching TV in the dead of night, the user can choose the left rear channel speaker RL and the right rear channel speaker RR near the sofa to sound, which will not cause any noise to the family, but if it is a banquet, you can choose The upper left channel speaker ATL and the upper right channel speaker ATR play the sky channel as background music without interfering with the banquet conversation.

另外，如果是多聲道複合電影或是音樂演唱會聲音輸入，則可選擇 「2 CHANNELS」或是「MULTI CHANNELS」，因為一般電影影片通常都包含雙聲道與多聲道音軌。此時，如果選擇「2 CHANNELS」，則「2 CHANNELS」燈號亮起，可以都不選、部分選或是全部選擇控制畫面的該等喇叭圖示，而雙聲道音樂可由所選取的喇叭來播放。如果是選擇「MULTI CHANNELS」，則「MULTI CHANNELS」燈號亮起，可以都不選、部分選或是全部選擇控制畫面的該等喇叭圖示，而多聲道的音訊可分配到相對應的各個喇叭。例如，在進行音效測試或是調整音場的時候，可以指定開啟或是關閉特定的喇叭發聲與否。In addition, if it is a multi-channel composite movie or music concert sound input, you can choose "2 CHANNELS" or "MULTI CHANNELS", because general movies usually contain two-channel and multi-channel audio tracks. At this time, if you select "2 CHANNELS", the "2 CHANNELS" light will be on. You can select none, some or all of the speaker icons on the control screen, and the two-channel music can be selected from the speakers Come play. If you select "MULTI CHANNELS", the "MULTI CHANNELS" light will be on. You can select none, some or all of the speaker icons on the control screen, and the multi-channel audio can be assigned to the corresponding Various speakers. For example, when testing sound effects or adjusting the sound field, you can specify whether to turn on or turn off a specific speaker.

較佳地，上述的中央影音處理單元10以及中央聲道喇叭C可是結合成一體，而後置音訊處理單元30以及超重低音聲道喇叭L也可結合成一體，可大幅簡化整體設計。Preferably, the aforementioned central audio-visual processing unit 10 and the center channel speaker C can be combined into one body, and the rear audio processing unit 30 and the subwoofer channel speaker L can also be combined into one body, which greatly simplifies the overall design.

綜上所述，本發明的主要特點在於利用智慧無線遙控制器讓使用者依據實際需要及個人的偏好而任意開關音響，進而擴大使用上的彈性。尤其，後置音訊處理單元可依據聲道控制指令對音訊進行解碼，同時根據聲道控制指令指定播放的喇叭。In summary, the main feature of the present invention is to use the smart wireless remote controller to allow the user to switch the sound arbitrarily according to actual needs and personal preferences, thereby expanding the flexibility of use. In particular, the post audio processing unit can decode the audio according to the channel control command, and at the same time specify the speaker to be played according to the channel control command.

此外，本發明的另一特點在於後置音訊處理單元是分別經由第一無線通道及第二無線通道的無線方式以接收來自中央影音處理單元的聲道控制指令以及音訊編碼訊號，因此，可省去後置音訊處理單元、中央影音處理單元之間的實體佈線，大幅減少整體的佈線，簡化配置設計，尤其是不會影響、破壞既有的裝潢。In addition, another feature of the present invention is that the rear audio processing unit receives channel control commands and audio coding signals from the central audio-visual processing unit via the first wireless channel and the second wireless channel, respectively. Therefore, it can save Remove the physical wiring between the rear audio processing unit and the central audio-visual processing unit, which greatly reduces the overall wiring and simplifies the configuration design, especially without affecting or destroying the existing decoration.
