请问各位原子的老师，我想做两路摄像头的输入，一路HDMI输出的视频流的切换，
always @(*) begin

if (switch_sdi == 1'b0) begin
hdmi_tx_pclk          = pixel_clk;
hdmi_tx_pclk_x5          = pixel_clk_5x;
hdmi_tx_hs = rx0_hsync;
hdmi_tx_vs = rx0_vsync;
hdmi_tx_de = rx0_de;
hdmi_tx_rgb = rx0_rgb;
end
else if (switch_sdi == 1'b1) begin
hdmi_tx_pclk          = pixel_clk_2;
hdmi_tx_pclk_x5          = pixel_clk_5x_2;
hdmi_tx_hs = rx1_hsync;
hdmi_tx_vs = rx1_vsync;
hdmi_tx_de = rx1_de;
hdmi_tx_rgb = rx1_rgb;
end
else  begin
hdmi_tx_pclk          = pixel_clk;
hdmi_tx_pclk_x5          = pixel_clk_5x;
hdmi_tx_hs = rx0_hsync;
hdmi_tx_vs = rx0_vsync;
hdmi_tx_de = rx0_de;
hdmi_tx_rgb = rx0_rgb;

end
end

assign hdmi_reset_n = pixel_clk_loken & pixel_clk_loken_2;

dvi_transmitter_top u_dvi_transmitter_top(
.pclk (hdmi_tx_pclk ),       // pixel clock
.pclk_x5 (hdmi_tx_pclk_x5 ),       // pixel clock x5
.reset_n (hdmi_reset_n ),       // reset

.video_din (hdmi_tx_rgb ),       // RGB888 video in
.video_hsync (hdmi_tx_hs ), // hsync data
.video_vsync (hdmi_tx_vs ), // vsync data
.video_de (hdmi_tx_de ),       // data enable

.tmds_clk_p (TMDS_clk_p ),
.tmds_clk_n (TMDS_clk_n ),
.tmds_data_p (TMDS_data_p ),
.tmds_data_n (TMDS_data_n ),
.tmds_oen    ()
);

以上是代码，我在用vio切换的时候，HDMI视频流输出没有画面，求解各位老师
