Figure 222. VSYNC Position With Respect to HSYNC
2.5.2 Embedded Syncs
Standards with embedded syncs insert the SAV and EAV codes into the data stream on the rising and falling
edges of AVID. These codes contain the V and F bits which also define vertical timing. Table 23 gives the
format of the SAV and EAV codes.
H equals 1 always indicates EAV. H equals 0 always indicates SAV. The alignment of V and F to the line and
field counter varies depending on the standard.
The P bits are protection bits:
P3 = V xor H; P2 = F xor H; P1 = F xor V; P0 = F xor V xor H

I2C Host Interface
Communication with the TVP5147 decoder is via an I2C host interface. The I2C standard consists of two
signals, the serial input/output data (SDA) line and the serial input clock line (SCL), which carry information
between the devices connected to the bus. A third signal (I2CA) is used for slave address selection. Although
an I2C system can be multimastered, the TVP5147 decoder functions as a slave device only.
