Embodiment Construction

[0021] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Referring to FIG. 1 , the position of the line auxiliary data space in the digital video sample data is illustrated, wherein the front section of the line auxiliary data space is used to transmit audio data, accounting for more than 16% of the sampling points of each line. The extended row auxiliary data occupies the remainder of the rear section of each row of row auxiliary data.

[0023] Referring to FIG. 2 , a data transmission method according to an embodiment of the present invention is illustrated. As shown in Figure 2, the data transmission method includes the following steps: S202, using an embedder at the data sending end that supports line extension data, embeds an extended line attachment of a specific format in a space other than the space occupied by audio data in the line attachment data space data, to transm...

Abstract

The invention discloses a data transmission method and a relative system, wherein the method comprises that S202, via an embedded at a data sender, embedding an expansion row attach data with special format at the space outside the space occupied by voice data in a row attach data space, to transmit pure load data of expansion attach data to a data receiver, S204, a de-embed device at the data receiver de-embed the pure load data in the row attach data, to receive the pure load data in the expanded row attach data. The invention can fully utilize idle space to improve the utilization of system bandwidth.

Description

technical field [0001] The present invention relates to the field of video communication, and more particularly relates to a data transmission method and system. Background technique [0002] There are line and field blanking periods in analog video for electron beam retrace. There is no valid image signal during the line and field blanking periods. After the analog video is digitized, a certain digital sequence is formed according to relevant standards (standard-definition SD according to ITU-R BT.601 and ITU-R BT.656, etc., high-definition HD according to SMPTE274M and SMPTE296M, etc.). Line and field blanking intervals also need to be sampled, and its data is a part of the digital sequence. Except for a small part of this part of data used for timing reference code, line number word, and CRC check word, the rest of a large amount of space is not used. Use, so this part of the unused data space can be used to transmit auxiliary data, this area is called the auxiliary dat...
