A multi-device system includes at least one media server system, a primary viewing device including a display screen, and a secondary device including a haptic output device. The at least one media server system includes a source of audio-video content and haptic content and is configured to transfer the audio-video content and the haptic content. The haptic content is associated with the audio-video content. The primary viewing device is configured to output the audio-video content received from the at least one media server system. The secondary device is configured to output the haptic content received from the at least one media server system as a haptic effect via the haptic output device.

A method for transmitting an uplink signal by a communication apparatus in a wireless communication system is discussed. The method includes multiplexing control information with at least one of a plurality of data blocks to generate a bit sequence; and transmitting the uplink signal including the bit sequence. When the control information includes a first type of control data, the control information is multiplexed with all of the plurality of data blocks. When the control information includes a second type of control data, the control information is multiplexed only with a specific data block among the plurality of data blocks. The first type of control data includes acknowledgement/negative acknowledgement (ACK/NACK) information, and the second type of control data includes channel quality information.

The invention relates to the art of communications and particularly to a video signal transmission method, apparatus, system and terminal, where the method includes: separating a current raw digital video signal acquired by a video camera core into a luminance signal and a chrominance signal; converting the luminance signal and the chrominance signal into an analog video signal; transmitting the analog video signal to a master control chip board through an electrically-conductive slip ring; and converting the analog video signal back into the current raw digital video signal in the master control chip board. With the video signal transmission method, apparatus, system and terminal according to embodiments of the invention, the integrity of the transmitted video signal can be improved to thereby guarantee the quality of the video signal.

Metadata comprising a set of gain values for creating a dominance effect is automatically generated. Automatically generating the metadata includes receiving multiple audio streams and a dominance criterion for at least one of the audio streams. A set of gains is computed for one or more audio streams based on the dominance criterion for the at least one audio stream and metadata is generated with the set of gains.

A method is provided for computing a predicted frame from a first and a second reference frames, the method comprising, for each block of pixels in the predicted frame, the acts of defining a first block of pixels in the first reference frame collocated with a third block of pixels which is the block of pixels in the predicted frame; defining a second block of pixels corresponding, in the second reference frame, to the first block of pixels along the motion vector of the first block from the first to second reference frames; computing a first set of coefficients allowing the transformation of the pixels of the first block into pixels of the second block; computing pixels of the third block using the first set of coefficients and pixels from a fourth block collocated in the first reference frame with the second block of pixels.

System, methods, apparatus, and computer-readable media to facilitate expansion of media device interface capabilities are provided. A state change with respect to one or more media devices may be detected. The state change may correspond to a second media device being communicatively coupled to, or communicatively decoupled from, a first media device. Consequent to the detecting, a set of interface ports, which are configured to interface with multimedia devices, may be determined. Configuration information may be generated based at least in part on the set of interface ports. The configuration information may be transferred to a sink device to indicate interface options based at least in part on the set of interface ports. Content may be transferred to the sink device based at least in part on audio and/or visual data via at least one interface port of the set of interface ports.
