Block Diagram of MPEG 1 Audio System 4.1 Proposed design of interface unit The block diagram of proposed design for several interface units is shown in Fig. 4 The interface between DSP and these inter face units for MPEG1 audio is done by 16 bit external data bus in SSP1605. CIU(Codec Interface Unit): The FPGA includes CIU for interfacing MPEG 1 MPEG 2 Coding Standards NTUA MPEG 1's coding scheme is illustrated in the Encoder Decoder Block diagrams of Figure 9 and 10 respectively. The underlying theoretical bases for the compression are actually the same as in H.261 and H.263, viz., it uses DCT transform to reduce the spatial redundancy, and motion compensation for temporal redundancy. MPEG 1 Coding Standard 國立臺灣大學 MPEG 1 content is used for such services as DAB (Digital Audio Broadcasting) and is the standard format on the Internet for quality video. pression Algorithms Overview. In MPEG 1, video is represented as a sequence of pictures, and each picture is treated as a two dimensional array of pixels (pels).

More details about Layer 3 can be found in [1] and [2]. Fig 2 shows the block diagram of a typical MPEG 1 2 Layer 3 encoder. Fig. 2: Block diagram of MPEG Layer 3 (MP3) encoding Filterbank The filterbank used in MPEG 1 Layer 3 belongs to the class of hybrid filterbanks. It is built by MP3 Hydrogenaudio Knowledgebase The MP3 data is the actual audio payload. The diagram shows that the MP3 header consists of a sync word which is used to identify the beginning of a valid frame. This is followed by a bit indicating that this is the MPEG standard and two bits that indicate that layer 3 is being used, hence MPEG 1 Audio Layer 3 or MP3.
