A method for processing and transmitting multimedia signals received from a plurality of channels are provided. The method may include receiving at least two multimedia signals from a plurality of channels, and generating a composite multimedia digital signal by coding the multimedia signals in a frame format. At least one of the multimedia signals may include a video signal. The frame format may include an active zone and a blanking zone, the active zone may be configured to encode at least part of the multimedia signals, and the blanking zone may be configured to encode format information. The method may further include converting at least part of the encoded multimedia signals in the active zone into analog signals to generate a composite multimedia signal. The method may further include transmitting the composite multimedia signal to a receiving device via a transmission medium.

Disclosed is a computer-implemented method for requesting and transmitting marketing images or video. The method includes receiving a communication from a remote terminal, identifying a user or a group of users that are associated with the received communication, identifying data associated with the identified user or the group of users, identifying goods or services using the identified data associated with the identified user or group of users, requesting marketing images or video from a marketing images or video supplying system that are relating to the identified goods or services, receiving the requested marketing images or video from the marketing images or video supplying system, and transmitting the received marketing images or video to the remote terminal.

A method for implementing an image data communication protocol by a panel is provided. The panel is communicatively coupled over a wireless network to alarm sensors and image sensors. The panel requests, under the image data communication protocol, image data from the image sensor by sending an image request packet to the image sensor. The panel receives, under the image data communication protocol, image data as an image data packet from the image sensor.

An image data processing method, an image display method, a data transmission apparatus and a storage medium. The image data processing method includes: storing an object data set to be transmitted into a first cache space, in which the object data set includes N pieces of consecutive image data sequentially arranged in a first order; recombining the N pieces of consecutive image data into M data subsets, in which each data subset includes N/M pieces of image data which are not adjacent to each other, sequentially selected from the N pieces of consecutive image data according to a first rule; and transmitting the M data subsets. And M is an integer greater than 1, and N is an integer multiple of M and greater than M.

A method for determining camera framing in a teleconferencing system comprises a process loop which includes acquiring an audio-visual frame from a captured a video data frame; detecting objects and extracting image features of the objects within the video data frame, ingesting the audio-visual frame into a context-based audio-visual map in an intelligent manner, and selecting targets from within the map for inclusion in an audio-video stream for transmission to a remote endpoint.
