1. A transmitting method for high-definition video data, comprising:
obtaining, by a transmitting device, high-definition video data with different color space formats;
processing, by the transmitting device, the high-definition video data into a data packet; and
transmitting, by the transmitting device, the data packet to a first communication module; wherein the transmission rate of the first communication module is not less than a first threshold, and the first communication module is configured to transmit the data packet;
wherein the transmitting device comprises a conversion chip and a first integrated circuit; the conversion chip and the first integrated circuit are independently integrated in the transmitting device respectively;
when the first integrated circuit is a field programmable gate array (FPGA) chip,
processing, by the transmitting device, the high-definition video data into the data packet comprises:
transmitting, by the transmitting device, the high-definition video data to the conversion chip based on the first interface protocol, transmitting, based on a second interface protocol, the high-definition video data obtained by the conversion chip to the FPGA chip, and encapsulating the high-definition video data based on a communication protocol by the FPGA chip to obtain the data packet; and
when the first integrated circuit is an application specific integrated circuit (ASIC) chip,
processing, by the transmitting device, the high-definition video data into the data packet comprises:
transmitting, by the transmitting device, the high-definition video data to the conversion chip based on the first interface protocol, transmitting, based on the second interface protocol, the high-definition video data obtained by the conversion chip to the ASIC chip, and encapsulating the high-definition video data based on the communication protocol by the ASIC chip to obtain the data packet; wherein
the first interface protocol comprises a HDMI protocol, a Type-C protocol, a DP protocol, a USB protocol, a MIPI protocol, a DVI protocol, or a VGA protocol; the second interface protocol comprises a transistor transistor logic (TTL) protocol, a low-voltage differential signaling (LVDS) protocol, the MIPI protocol, or a custom interface protocol; and the communication protocol comprises a user datagram protocol (UDP), a transmission control protocol (TCP), or a custom communication protocol.
