在這裡http://www.38c.com.tw/newversion/left/news.htm 但他的套件是整組而不是只有機版 可能無法拆開分別買 也就是說是直接買一台完整的dvdplay 差別是組裝好跟沒組裝好  |

1. 如果你機器上的晶片是 ES4318，那麼你的機器 就不應該有 AC3 5.1 聲道類比輸出。因為 ES4318 並沒有把數位訊號解成5.1聲道的能力。 2. 有些擴大機只有「純六聲道」，並沒有內建AC-3、DTS 解碼功能。 因此，他們需要有AC-3 、DTS 5.1 聲道輸出的 DVD player。 3. 我越來懷疑市面上可能有 假的「雙解碼」（指同時具備AC3、DTS 5.1 聲道類比輸出）與 假的「AC3 5.1 聲道類比輸出」的 DVD player。 當然，這必須靠網友提供更多的資訊才能確定。 |

剛剛把dvdplayer拆了 T T
証明是這台沒錯 以下是ESS的說明: The ES4318 Digital Video Disc (DVD) processor is a single-chip solution for a DVD player that integrates MPEG video decoding, DVD system navigation, Content Scrambling System (CSS), and DolbyTM Digital (AC-3) and MPEG audio decoding. The fully programmable ES4318 is based on a proprietary ESS architecture. It offers the best feature set in comparison to any currently existing DVD chip, and a glueless interface to various peripheral components. The ES4318 is the most cost effective solution in its class with an integration level and quality that set new benchmarks. Video The ES4318 processor is capable of decoding DolbyTM Digital (AC-3) or DTS digital surround, simultaneously with MPEG-1 or MPEG-2 video. For embedded applications, the ES4318's internal RISC processor can be used in place of a microcontroller to provide all system control, DVD system navigation, CSS decryption, and many other features. On-chip, multi-tap filters provide arbitrary scaling with state of the art SmartScaleTM technology useful for video standards conversion. SmartStreamTM technology from ESS provides video error concealment and video post-processing, leading to the highest playability and video quality. Other features included in the ES4318 are video letterbox display, DVD Sub-Picture overlay, and On-Screen Display. The ES4318 provides a glueless 8/16-bit parallel interface to most DVD servo/loaders. It connects directly with 8/16-bit ROM and 16-bit SDRAM/EDO. An 8-bit YUV video interface supports many TV encoders. General purpose auxiliary pins are provided to control various peripheral devices. A standard I2S interface supports popular audio DACs and ADCs. The ES4318 also features a direct S/PDIF output. A block diagram of a typical stand-alone system using the ES4318 with the glueless SDRAM interface appears below. The DVD system stream from a DVD disc is passed to the ES4318 through the 8-bit/16-bit parallel host interface. The ES4318 parses the system layer and demultiplexes the audio and video streams. Audio is decoded and passed through the I2S audio serial bus to an external audio DAC and then to the speakers. Video is decoded and output as YUV pixels to an NTSC or PAL video encoder. System control and housekeeping functions (keypad and remote control) are also provided on-chip. * Single-chip DVD video decoder in a 208-pin PQFP package * MPEG-1 system and MPEG-2 program streams parsing supported * Programmable multimedia processor architecture * Compatible with Audio CD, VideoCD, VCD 3.0, and Super VideoCD (SVCD) * DVD Navigation 1 * Built-in Content Scrambling System (CSS) circuitry * Pan & Scan and Letter-Box conversions * Trick modes include Slow, Fast Forward, Fast Reverse, Step, and Goto * Sub-Picture decoder supports karaoke/subtitling functions * 4-bit On-Screen Display (OSD) with 4-bit blending * 8-bit YUV component video output Audio * Built-in Karaoke key-shift function * DolbyTM Digital 2-channel downmix audio output for DolbyTM * Dolby Pro Logic * Linear PCM streams for 24 bit/96KHz * Concurrent S/PDIF out and 2-channel audio output * Sensaura Dolby Digital Virtual Suround * DTS Digital Surround 2-channel downmix stereo output * S/PDIF output for encoded AC-3, DTS Digital output or Linear PCM Peripheral * Glueless interface to DVD loaders (ATAPI or A/V bus I/F) * Bidirectional I2S audio interface * Direct servo/loader interface * 8 general-purpose auxiliary ports * Single 27 MHz clock input Smart Technology * SmartZoomTM for motion zoom and pan * SmartScaleTM for NTSC to PAL conversion and vice versa * SmartStreamTM for video error concealment; supports 看起來ES4318好像是沒5.1CH 但機器上是ES4318F的喔!!!! ESS站上又無此型號晶片 (仿冒???) @@ 而且它生產的ES4408和ES4408FD晶片是有無解DTS的差別 故說不定ES4318F真的有5.1CH........ (可是若沒有的話它的5.1CH是如何模擬出來的???????) 不過沒差 反正家裏的AMP只有2CH輸出.......

1.
ES4318F 只有兩個聲道。（使用ES4318F 這顆IC的兩聲道 DVD player多如過江之鯽，因此不必懷疑它確實只有兩聲道） ES4408F 才有 AC-3 5.1 聲道。 ES4408FD 才同時有AC-3 5.1 聲道以及 DTS 5.1 聲道。 2. 不知 prost 先生的這台機器裡是否有 QS 開頭的 IC? |

其實很多DVD player 面板或外觀皆相同....但內部使用的晶片卻大不相同,不然怎會有一樣的外型,卻有賣3990,4888,5888.......等不同價格,我還是覺得盡量不要在大型賣場,購買電器用品......

嗯....... 據印像中"好像"沒有(不想再拆一次了,SORRY) 除了比較有名的ANALOG DEVICES的ADV7170KS外 還有兩顆較大的晶片 牌子不知(因為找不到資料) 型號是WM-XWM8736及0015PR/V54C365164VC17 加上幾顆飛利普的小IC 大概就這麼多了............

我也是有一點點懷疑.... 但是如果晶片無法解碼,有辦法模擬嗎?

1. 謝謝您辛苦拆機。 2. WM8736 是一顆六聲道 DAC ，裡面其實包含了三組雙聲道 DAC。 因此，WM8736 可以把 ES4408F 或 ES4408FD 的三個獨立的 數位音訊輸出解成六個類比聲道。 但是 ES4308F 卻只有一個數位音訊輸出，因此最多也只能解成兩個聲道。 因此我猜測（只是猜測，因為沒有看到實體），一部機器如果用了ES4308F ，卻有六個聲道輸出，它很有可能是把ES4308F 的一個輸出同時接到三組雙 聲道DAC的輸入，然後在每個聲道加幾顆不到幾塊錢的電阻、電容來濾除高音 、低音或中音，讓每個聲道聽起來不同。 用這種伎倆來冒充 5.1 環繞音效，我認為：是有人會幹這種事。尤其是具備 「把差的東西做的更差」能力的那些人。 這種人，很久很久以前台灣也有，他們就是有能力把「單聲道兩個喇叭」當成 「立體音響」來賣、「雙聲道四個喇叭」當成「四聲道」來賣...等等。 只是現在，戲碼改由另外一個國家的人演出「續集」罷了。 |

1. 市面上有 Virtual Surround （虛擬環繞）晶片已經有很多年了。 這種晶片的「正規」用法，是用前面的兩顆喇叭模擬出不存在的 後置喇叭。 2. 由發弟、prost兩位先進所提供的寶貴資料，我們似乎已經發現了 DVD player 的「新品種」。這種「新品種」當然只有「全世界最 聰明」的民族才會生產。 |

明天我也去借一台面板相同的機器,拆來看看是否售價不同,用料就不同...
到時後再麻煩DVD6502兄解答,好嗎?? p.s.要注意那些晶片 |
