functional block diagram the adv601lc adheres to international standard ccir-601 for studio quality digital video. the codec also supports a range of field sizes and rates providing high performance in computer, pal, ntsc, or still image environments. the adv601lc is designed only for real-time interlaced video, full frames of video are formed and processed as two independent fields of data. the adv601lc supports the field rates and sizes in table i. note that the maximum active field size is 768 by 288. the maximum pixel rate is 14.75 mhz. the adv601lc has a generic 16-/32-bit host interface, which includes a 512-position, 32-bit wide fifo for compressed video. with additional external hardware, the adv601lcs host inter- face is suitable (when interfaced to other devices) for moving com- pressed video over pci, isa, scsi, sonet, 10 base t, arcnet, hdsl, adsl, and a broad range of digital interfaces. for a full description of the host interface, see the host interface section. the compressed data rate is determined by the input data rate and the selected compression ratio. the adv601lc can a chieve a near constant compressed bit rate by using the current field statistics in the off-chip bin width calculator on the external dsp or host. the process of calculating bin widths on a dsp or host can be adaptive, optimizing the compressed bit rate in real time. this feature provides a near constant bit rate out of the host interface in spite of scene changes or other types of source material changes that would otherw ise create bit rate burst conditions. for more information on the quantizer, see the programmable quantizer section. the adv601lc typically yields visually loss-less compression on natural images at a 4:1 compression ratio. desired image quality levels can vary widely in different applications, so it is advisable to evaluate image quality of known source material at different compression ratios to find the best compression range for the application. the sub-band coding architecture of the adv601lc provides a number of options to stretch compres- sion performance. these options are outlined on in the apply- ing the adv601lc section. table i. adv601lc field rates and sizes active active total total standard region region region region field rate pixel rate name horizontal vertical 1 horizontal vertical (hz) (mhz) 2

adv601lc C3C rev. 0 internal architecture the adv601lc is composed of eight blocks. three of these blocks are interface blocks and five are processing blocks. the interface blocks are the digital video i/o port, the host i/o port, and the external dram manager. the processing blocks are the wavelet kernel, the on-chip transform buffer, the programmable quantizer, the run length coder, and the huffman coder. digital video i/o port provides a real-time uncompressed video interface to support a broad range of component digital video formats, including d1. host i/o port and fifo carries control, status, and compressed video to and from the host processor. a 512 position by 32-bit fifo buffers the com- pressed video stream between the host and the huffman coder. dram manager performs all tasks related to writing, reading, and refreshing the external dram. the external host buffer dram is used for reordering and buffering quantizer input and output values. wavelet kernel (filters, decimator, and interpolator) gathers statistics on a per field basis and includes a block of filters, interpolators, and decimators. the kernel calculates forward and backward bi-orthogonal, two-dimensional, sepa- rable wavelet transforms on horizontal scanned video data. this block uses the internal transform buffer when performing wave- let transforms calculated on an entire images data and so eliminates any need for extremely fast external memories in an adv601lc-based design. on-chip transform buffer provides an internal set of sram for use by the wavelet trans- form kernel. its function is to provide enough delay line storage to support calculation of separable two dimensional wavelet transforms for horizontally scanned images. programmable quantizer quantizes wavelet coefficients. quantize controls are calculated by the external dsp or host processor during encode operations and de-quantize controls are extracted from the compressed bit stream during decode. each quantizer bin width is computed by the bw calculator software to maintain a constant com- pressed bit rate or constant quality bit rate. a bin width is a per block parameter the quantizer uses when determining the num- ber of bits to allocate to each block (sub-band). run length coder performs run length coding on zero data and models nonzero data, encoding or decoding for more efficient huffman coding. this data coding is optimized across the sub-bands and varies depending on the block being coded. huffman coder performs huffman coder and decoder functions on quantized run-length coded coefficient values. the huffman coder/de- coder uses three rom-coded huffman tables that provide ex- cellent performance for wavelet transformed video. general theory of operation the adv601lc processors compression algorithm is based on the bi-orthogonal (7, 9) wavelet transform, and implements field independent sub-band coding. sub-band coders transform two- dimensional spatial video data into spatial frequency filtered sub-bands. the quantization and entropy encoding processes provide the adv601lcs data compression. the wavelet theory, on which the adv601lc is based, is a new mathematical apparatus first explicitly introduced by morlet and grossman in their works on geophysics during the mid 80s. this theory became very popular in theoretical physics and applied math. the late 80s and 90s have seen a dramatic growth in wavelet applications such as signal and image processing. for more on wavelet theory by morlet and grossman, see decompo- sition of hardy functions into square integrable wavelets of con- stant shape (journal citation listed in references section). encode path decode path wavelet kernel filter bank adaptive quantizer run length coder & huffman coder compressed data figure 2. encode and decode paths references for more information on the terms, techniques and underlying principles referred to in this data sheet, you may find the follow- ing reference texts useful. a reference text for general digital video principles is: jack, k., video demystified: a handbook for the digital engineer (high text publications, 1993) isbn 1-878707-09-4 three reference texts for wavelet transform background infor- mation are: vetterli, m., kovacevic, j., wavelets and sub-band coding (prentice hall, 1995) isbn 0-13-097080-8 benedetto, j., frazier, m., wavelets: mathematics and applica- tions (crc press, 1994) isbn 0-8493-8271-8 grossman, a., morlet, j., decomposition of hardy functions into square integrable wavelets of constant shape , siam. j. math. anal., vol. 15, no. 4, pp 723-736, 1984
adv601lc C4C rev. 0 the wavelet kernel this block contains a set of filters and decimators that work on the image in both horizontal and vertical directions. figure 6 illustrates the filter tree structure. the filters apply carefully chosen wavelet basis functions that better correlate to the broad- band nature of images than the sinusoidal waves used in dis- crete cosine transform (dct) compression schemes (jpeg, mpeg, and h261). an advantage of wavelet-based compression is that the entire image can be filtered without being broken into sub-blocks as required in dct compression schemes. this full image filtering eliminates the block artifacts seen in dct compression and offers more graceful image degradation at high compression ratios. the availability of full image sub-band data also makes image processing, scaling, and a number of other system fea- tures possible with little or no computational overhead. the resultant filtered image is made up of components of the original image as is shown in figure 3 (a modified mallat tree). note that figure 3 shows how a component of video would be filtered, but in multiple component video luminance and color components are filtered separately. in figure 4 and figure 5 an actual image and the mallat tree (luminance only) equivalent is shown. it is important to note that while the image has been filtered or transformed into the frequency domain, no compres- sion has occurred. with the image in its filtered state, it is now ready for processing in the second block, the quantizer. understanding the structure and function of the wavelet filters and resultant product is the key to obtaining the highest perfor- mance from the adv601lc. consider the following points: ? the data in all blocks (except n) for all components are high pass filtered. therefore, the mean pixel value in those b locks is typically zero and a histogram of the pixel values in these blocks will contain a single hump (laplacian distribution). ? the data in most blocks is more likely to contain zeros or strings of zeros than unfiltered image data. ? the human visual system is less sensitive to higher frequency blocks than low ones. ? attenuation of the selected blocks in luminance or color com- ponents results in control over sharpness, brightness, contrast and saturation. ? high quality filtered/decimated images can be extracted/created without computational overhead. through leverage of these key points, the adv601lc not only com presses video, but offers a host of application features. please see the applying the adv601lc section for details on getting the most out of the adv601lcs sub-band coding architecture in different applications. block a is high pass in x and decimated by two. block b is high pass in x, high pass in y, and decimated by eight. block c is high pass in x, low pass in y, and decimated by eight. block d is low pass in x, high pass in y, and decimated by eight. block e is high pass in x, high pass in y, and decimated by 32. block f is high pass in x, low pass in y, and decimated by 32. block g is low pass in x, high pass in y, and decimated by 32. block h is high pass in x, high pass in y, and decimated by 128. block i is high pass in x, low pass in y, and decimated by 128. block j is low pass in x, high pass in y, and decimated by 128. block k is high pass in x, high pass in y, and decimated by 512. block l is high pass in x, low pass in y, and decimated by 512. block m is low pass in x, high pass in y, and decimated by 512. block n is low pass in x, low pass in y, and decimated by 512. n m l k i h j g f e c b d a figure 3. modified mallat diagram (block letters correspond to those in filter tree)

adv601lc C7C rev. 0 the programmable quantizer this block quantizes the filtered image based on the response profile of the human visual system. in general, the human eye cannot resolve high frequencies in images to the same level of accuracy as lower frequencies. through intelligent quantiza- tion of information contained within the filtered image, the adv601lc achieves compression without compromising the visual quality of the image. figure 7 shows the encode and de- code data formats used by the quantizer. figure 8 shows how a typical quantization pattern applies over mallat block data. the high frequency blocks receive much larger quantization (appear darker) than the low frequency blocks (appear lighter). looking at this figure, one sees some key point concerning quantization: (1) quantization relates directly to frequency in mallat block data and (2) levels of quantization range widely from high to low frequency block.

adv601lc C19C rev. 0 video interface the adv601lc video interface supports two types of compo- nent digital video (d1) interfaces in both compression (input) and decompression (output) modes. these digital video inter- faces include support for the multiplexed philips 4:2:2 and ccir-656/smpte125minternational standard. video interface master and slave modes allow for the generation or receiving of synchronization and blanking signals. definitions for the different formats can be found later in this section. for recommended connections to popular video decoders and encoders, see the connecting the adv601lc to popular video decoders and encoders section. a complete list of supported video interfaces and sampling rates is included in table v. table v. component digital video interfaces nominal bits/ color date name component space sampling rate (mhz) i/f width ccir-656 8 ycrcb 4:2:2 27 8 multiplex philips 8 yuv 4:2:2 27 8 internally, the video interface translates all video formats to one consistent format to be passed to the wavelet kernel. this con- sistent internal video standard is 4:2:2 at 16 bits accuracy. vitc and closed captioning support the video interface also supports the direct loss-less extraction of 90-bit vitc codes during encode and the insertion of vitc codes during decode. closed captioning data (found on active video line 21) is handled just as normal active video on an active scan line. as a result, no special dedicated support is necessary for closed captioning. the data rates for closed captioning data are low enough to ensure robust operation of this mechanism at compression ratios of 50:1 and higher. note that you must include video line 21 in the adv601lcs de- fined active video area for closed caption support. 27 mhz nominal sampling there is one clock input (vclk) to support all internal process- ing elements. this is a 50% duty cycle signal and must be syn- chronous to the video data. internally this clock is doubled using a phase locked loop to provide for a 54 mhz internal processing clock. the clock interface is a two pin interface that allows a crystal oscillator to be tied across the pins or a clock oscillator to drive one pin. the nominal clock rate for the video interface is 27 mhz. note that the adv601lc also supports a pixel rate of 13.5 mhz. video interface and modes in all, there are seven programmable features that configure the video interface. these are: ? encode-decode control in addition to determining what functions the internal pro- cessing elements must perform, this control determines the direction of the video interface. in decode mode, the video interface outputs data. in encode mode, the interface receives data. the state of the control is reflected on the enc pin. this pin can be used as an enable input by external line driv- ers. this control is maintained by the host processor. ? master-slave control this control determines whether the adv601lc generates or receives the vsync, hsync, and field signals. in master mode, the adv601lc generates these signals for external hardware synchronization. in slave mode, the adv601lc receives these signals. note that some video formats require the adv601lc to operate in slave mode only. this control is maintained by the host processor. ? 525-625 (ntsc-pal) control this control determines whether the adv601lc is operating on 525/ntsc video or 625/pal video. this information is used when the adv601lc is in master and decode modes so that the adv601lc knows where and when to generate the hsync, vsync, and field pulses as well as when to insert the sav and eav time codes (for ccir-656 only) in the data stream. this control is maintained by the host pro- cessor. table vi shows how the 525-625 control in the mode control register works. table vi. square pixel control, 525-625 control, and video formats max max 525-625 horizontal field control size size ntsc-pal 0 720 243 ccir-601 ntsc 1 720 288 ccir-601 pal ? bipolar/unipolar color component this mode determines whether offsets are used on color com- ponents. in philips mode, this control is usually set to bipo- lar, since the color components are normal twos-compliment signed values. in ccir-656 mode, this control is set to uni- polar, since the color components are offset by 128. note that it is likely the adv601lc will function if this control is in the wrong state, but compression performance will be degraded. it is important to set this bit correctly. ? active area control four registers hstart (horizontal start), hend (horizon- tal end), vstart (vertical start) and vend (vertical end) determine the active video area. the maximum active video area is 720 by 288 pixels for a single field. ? video format this control determines the video format that is supported. in general, the goal of the various video formats is to support glueless interfaces to the wide variety of video formats periph- eral components expect. this control is maintained by the host processor. table vii shows a synopsis of the supported video formats. definitions of each format can be found later in this section. for video interface pins descriptions, see the pin function descriptions.

(mo dulo 32) this data is the quantized and entropy coded block sub-band data. the datas length is dependent on block size and entropy coding so it is therefore variable in length. this field is filled with 1s making it modulo 32 bits in length. any huffman decode process can be interrupted and reset by any unexpectedly received # delimiter following a bit error or synchronization problem. #eos 0xffffffffc0ffffff the host sends the #eos (end of sequence) to the adv601lc during decode after the last field in a sequence to indicate that the field sequence is complete. the adv601lc does not append this code to the end of encoded field sequences; it must be added by the host. bit error tolerance bit error tolerance is ensured because a bit error within a huffman coded stream does not cause #delimiter symbols to be misread by the adv601lc in decode mode. the worst error that can occur is loss of a complete block of huffman data. with the adv601lc, this type of error results only in some blurring of the decoded image, not complete loss of the image.

adv601lc C30C rev. 0 getting the most out of adv601lc the unique sub-band block structure of luminance and color components in the adv601lc offers many unique application benefits. analog devices will offer a feature software library as well as separate feature application documentation to help users exploit these features. the following section provides an o ver- view of only some of the features and how they are achieved with the adv601lc. please refer to figures 2 and 3 as necessary. higher compression with interfield techniques the adv601lc normally operates as a field-independent codec. however, through use of the sub-bands it is possible to use the adv601lc with interfield techniques to achieve even higher levels of compression. in such applications, each field is not compressed separately, thus accessing the compressed bit stream can only be done at specific points in time. there are two general ways this can be accomplished: ? subsampling high frequency blocks the human visual system is more sensitive to interframe motion of low frequency block than to motion in high fre- quency blocks. the host software driver of the adv601lc allows exploitation of this option to achieve higher com- pression. n ote that the compressed bit stream can only be accessed at points where the high frequency blocks have just been updated. ? updating the image with motion detection in applications where the video is likely to have no motion for extended periods of time (video surveillance in a vacant build- ing, for instance), it is only necessary to update the image either periodically or when motion occurs. by using the wave- let sub-bands to detect motion (see later in this section), it is possible to achieve very high levels of compression when motion is infrequent. scalable compression technology the adv601lc offers many different options for scaling the image, the compressed bit stream bandwidth and the processing horsepower for encode or decode. because the adv601lc employs decimators, interpolators and filters in the filter bank, the scaling function creates much higher quality images than achieved through pixel dropping. mixing and matching the many scaling options is useful in network applications where transmission pipes may vary in available bit rate, and decode/ encode capabilities may be a mix of software and hardware. these are the key options: ? extract scaled images by factors of 2 from the compressed bit stream this is useful in video editing applications where thumbnail sketches of fields need to be displayed. in this case, editing software can quickly extract and decode the desired image. this technique eliminates the burden of decoding an entire image and then scaling to the desired size. ? use software to decode bit stream decoding an entire ccir-601 resolution image in real time at 50/60 fields per second does require the adv601lc hard- ware. analog devices provides a bit-exact adv601lc simulator that can decode a scaled image in real time or a full- size image off-line. image size and frame rates depend on the performance of the host processor. ? scale bit stream the compressed video bit stream was created with simple parsing in mind. this type of parsing means that a lower resolution/lower bandwidth bit stream can be extracted with little computational burden. generally, this effect is accom- plished by selecting a subset of lower frequency blocks. this technique is useful in applications where the same video source material must be sent over a range of different commu- nication pipes {i.e., isdn (128 kbps), t1 (1.5 mbps) or t3 (45 mbps)}. ? use software to encode in this case, a host cpu could encode a smaller image size and fill in high frequency blocks with zeros. again, image quality would depend on the performance of the host. the bin width may be set to zero, zeroing out the data in any particular mallat block. parametric image filtering the adv601lc offers a unique set of image filtering capa- bili ties not found in other compression technologies. the adv601lc quantizer is capable of attenuating any or all of the luminance or chrominance blocks during encode or decode. here are some of the possible applications: ? parametric softening of color saturation and contrast during encode or decode trade off image softness for higher compression. attenua- tion of the higher frequency blocks during encode leads to softer images, but it can lead to much higher compression performance. ? color saturation control this effect is achieved by controlling gain of low pass chromi- nance blocks during encode or decode. ? contrast control this effect is achieved by controlling the gain of the low fre- quency luminance blocks during encode or decode. ? fade to black this effect achieved by attenuation of luminance blocks. mixing of two or more images blocks from different images can be mixed into the bit stream and then sent to the adv601lc during decode. the result is high quality mixing of different images. this also provides the capability to fade from one image to the next. edge or motion detection in certain remote video surveillance and machine vision applica- tions, it is desirable to detect edges or motion. edges can be quickly found through evaluation of the high frequency blocks. motion searches can be achieved in two ways: ? evaluation of the smallest luminance block . because the size of the smallest block is so mcuh smaller than the others, the computational burden is significantly less than doing an evaluation over the entire image. ? polling the sum of squares registers. because large changes in the video data create patterns, it is possible to detect motion in the video by polling the sum of squares registers, looking for patterns and changes.
