| CVE5 High Definition Video Encoder DVD Digital Camera Driving the Digital Lifestyle Digital TV Imaging IP Cores Product Brief Description Zoran Corporation 1390 Kifer Road Sunnyvale, CA 94086-5305 Te l 408.523.6500 Fax 408.523.6501 www.zoran.com Zoran's CVE5 High Definition Video Encoder is a silicon-efficient, high-quality Intellectual Property Core for video IC designs requiring the high definition TV encoding. The CVE5 encodes YCrCb, 4:2:2 digital video into the 720p, 1080i, 480p and 576p standards. All NTSC, PAL, or SECAM TV standards for interlaced output are also supported. CVE5 supports vertical blanking interval (VBI) encoding, including closed caption, teletext, WSS and CGMS-A encoding. CVE5 also includes support for Macrovision 7.1.L1, the copy protec- tion scheme used in DVD players and set-top boxes. Six separate output busses for Y, Composite, Chroma, and RGB provide for flexibility in connection and multiplexing to DACs. The CVE5 High Defintion video encoder greatly reduces the risk and time involved when integrating this function into an IC. When combined with Zoran's Frame-It-1 Video Deinterlacer, CVE5 provides an quality solution for high definition video encoding. Features * 720p, 1080i, 480p and 576p standards supported * Encodes 4:2:2 YCrCb into all variations of NTSC, PAL or SECAM interlaced TV standards for interlaced output * Simultaneous output of composite video, S-video and component video supported * Dual chroma paths for optimal output of both composite video and S-Video component video * CCIR 601, 604 and 656 and SMTPE 253 standards supported * Macrovision 7.1.L1 copy protectionn * * * * * * * * 47-tap luma filter Outputs 10-bit data to DACs Vertical Blanking Interval (VBI) encoding support Closed caption, teletext, WSS & CGMS-A encoding Uniform 54 MHz clock; fully synchronous design 4x oversampling of luminance and chrominance filter for interlace mode 2x oversampling for progressive scan mode Process technology independent "softcore" Integrated Circuit Applications * HDTV * Digital TV * Set top box decoders * Any system requiring high definition TV encoding Deliverables * Compilable Verilog source code * Bit accurate, cycle accurate C model * Synopsis synthesis scripts * Test input files * Documentation CVE5 High Definition Encoder Block Diagram tt_req tt_data Y Noise reduction and edge enhancement Cb 4x Upsampling Filter Y 2x 45 tap Upsampling Filter Y 2x 15 tap Upsampling Filter Add Sync Setup Add VBI Pulse (WSS/Closed Y Caption/Teletext) D/A Y D/A Composite D/A Cr, Cb Cb 2x Upsampling Filter Cr 2x Upsampling Filter Cr 4x Upsampling Filter Hblank vblank clk27 clk54 clk74.25 clk148.5 data_write data_read r/w control Register file Standard Definition and High Definition Interlaced and Progressive Timing Generator and Macrovision Control Chroma Modulation and Burst Generation C D/A SECAM Chroma Modulation YUV to RGB R/Pr G/Y B/Pb 7/16/04-TS CVE5-PB-1.0 CVE5 High Definition Video Encoder Driving the Digital Lifestyle Product Brief CVE5 High Definition Encoder Logical Pinout slave_mode SLAVE MODE INTERFACE v_blank_in h_blank_in field_in v_blank h_blank field y[9:0] c[9:0] composite[9:0] luma[9:0] chroma[9:0] red[9:0] green[9:0] blue[9:0] comp_sync VIDEO OUTPUT INTERFACE VIDEO INPUT INTERFACE TELETEXT INPUT INTERFACE tt_req tt_data HOST BUST INTERFACE cpu_clk cpu_reset_l reg_rdy reg_rd_wm reg_addr[5:0] reg_din[7:0] cve4_reg_ack cve4_dout[7:0] cve4_dout_rdy clk[6:0] reset_l resync resync_field resync_linenum[9:0] resync_pixel[9:0] extra_halfline burst_blank at_blank vsync5 firstvideoline mv_disable scan_enable CVE5 High Definition Video Encoder IP Core PARTIAL SLAVE INTERFACE CUSTOMER SPECIFIC INTERFACE For more information, contact Zoran's Santa Clara office or the office nearest you: Canada Zoran Toronto Lab Te l : (416) 690-3356 Fax: (416) 690-3363 China Zoran China Office Tel: 86-755-83993777 Fax: 86-755-83220889 Hong Kong Zoran Asia Pacific Ltd.
