The source core accepts video, audio, and auxiliary channel data streams. The core produces a TMDS/

TERC4 encoded data stream that would typically connect to the high-speed transceiver parallel data

inputs.

Central to the core is the TMDS/TERC4 encoder. The encoder processes either video or auxiliary data.

Source TMDS/TERC4 Encoder

The source TMDS/TERC4 encoder implements 8-bit to 10-bit and 4-bit to 10-bit algorithms as defined in

the HDMI Specification Ver.2.0. Each channel has its own encoder.

The encoder processes symbol data at 1, 2, or 4 symbols per clock.

When the encoder operates in 2 or 4 symbols per clock, it also produces the output in the form of two or

four encoded symbols per clock.

The TMDS/TERC4 encoder also produces digital visual interface (DVI) signaling when you deassert the

mode input signal. DVI signaling is identical to HDMI signaling, except for the absence of data and video

islands and TERC4 auxiliary data.

Source Video Resampler

The core resamples the video data based on the current color depth.

The video resampler consists of a gearbox and a dual-clock FIFO (DCFIFO).

The resampler adheres to the recommended phase encoding method described in HDMI Specification

Ver.1.4b.

• The phase counter must register the last packing-phase (pp) of the last pixel of the last active line.

• The resampler then transmits the pp value to the attached sink device in the General Control Packet

(GCP) for packing synchronization.
