A data transmission method, a data loading device, a data parsing device, and a data transmission system are described herein. The methods include acquiring original video data, acquiring data to be transmitted, processing the original video data according to the data to be transmitted to obtain target video data, and displaying the target video data and the original video data. The methods may further include after displaying the target video data and the original video data, collecting the displayed target video data and original video data, parsing the original video data and the target video data to obtain the data to be transmitted.

The present invention relates to a video signal transmission device and the like that can support a variety of system specifications. The device includes a packer unit, an encoder unit, and a serializer. The packer unit generates, from a video signal of one or more pixels, a plurality of block signals having a packet configuration of size corresponding to the number of pixels and the number of tone bits of a color signal constituting a video signal. At this time, a control signal including a pulse having a width corresponding to the number of pixels and the number of tone bits is also generated. The encoder unit applies encoding processing having encoding efficiencies that are different between a first period and a second period of a control signal that are distinguished depending on existence or non-existence of a pulse to the block signals.

Embodiments of systems and methods for the sending, delivery and receiving of faxes are disclosed herein. In particular, certain embodiments include a fax connector that may be deployed at a user's site, and a faxing system that may be deployed remotely from the user's site. The fax connector can be accessed at the user's site over a computer based network in order to perform functions associated with faxing, including sending, receiving and obtaining status on faxes. The fax connector deployed at the user's site communicates with the remotely deployed faxing system to send, receive, obtain status on, or perform other functions associated with, faxing.

The present invention provides a method and an apparatus for transmitting and receiving a broadcast signal so as to adjust a colour range of content. The method for transmitting a broadcast signal according to an embodiment of the present invention comprises the steps of: encoding video data and signalling information including metadata with respect to the gamut of the video data; generating a broadcast signal including the encoded video data and signalling information; and transmitting the generated broadcast signal.

In a display system, a wireless transmitter receives video data and a CEC command from an AV amplifier, determines whether the received CEC command is a preset command or not, generates a confirmation command if it is determined that the CEC command is a preset command, and transmits the video data and the CEC command received from the AV amplifier and the confirmation command, to a projector. The projector receives the video data, the CEC command and the confirmation command transmitted from the wireless transmitter, and determines whether the received CEC command and confirmation command correspond to each other or not.

An apparatus and method for intra-predicting an image are provided. The method includes: obtaining, based on restored neighboring pixels of a chrominance block and restored neighboring pixels of a luminance pixel corresponding to the chrominance block, parameters representing a correlation between the chrominance block that is to be intra-predicted and a luminance block; and predicting, using the parameters, the chrominance block from the luminance block, wherein the obtaining the parameters includes performing a predetermined operation on the restored neighboring pixels of the chrominance block and the restored neighboring pixels of the luminance block, and wherein the predetermined operation comprises an adaptive scaling process of changing bit depths of the parameters to reduce a size of a look-up table and prevent an occurrence of overflow.
