20140362919 | COHERENCE GROUPS: REGION DESCRIPTORS FOR LOW BIT RATE ENCODING - The invention is directed to an efficient way for encoding and decoding video. Embodiments include identifying different coding units that share a similar characteristic. The characteristic can be, for example: quantization values, modes, block sizes, color space, motion vectors, depth, facial and non-facial regions, and filter values. An encoder may then group the units together as a coherence group. An encoder may similarly create a table or other data structure of the coding units. An encoder may then extract the commonly repeating characteristic or attribute from the coding units. The encoder may transmit the coherence groups along with the data structure, and other coding units which were not part of a coherence group. The decoder may receive the data, and utilize the shared characteristic by storing locally in cache, for faster repeated decoding, and decode the coherence group together. | 2014-12-11 |

20140363017 | Signal Receiving Structure of Wireless Microphone - A signal receiving structure of a wireless microphone contains: a host controlled by a RS485 and connecting with a plurality of RS485 receivers via plural signal cables, such that signal receiving ranges of the plurality of RS485 receivers are overlapped so as to expand a total receiving range, and any one of the plurality of RS485 receivers transmits at least one microphone signal back to the host through RS485 remote-control communication interface after receiving the at least one microphone signal, and power is supplied to the plural signal cables from the host, thus expanding using range of at least one wireless microphone. At least one receiving module in the plurality of RS485 receivers receives the at least one microphone signal, acquires a strong one of the at least one microphone signal by using automatic selection, and outputs the strong one of the at least one microphone signal to the host. | 2014-12-11 |
20140363018 | Sound Processing Unit, Sound Processing System, Audio Output Unit And Display Device - Practical speaker connection is identified using a device having a sound channel of a 5.1 channel or 7.1 channel, and a device is provided that can easily reproduce the optimum multiple channels. Actual speaker arrangement can be identified by, for example, measuring the impedance of a terminal at the side of an audio amplifier. If incorrect connection is found, a warning is issued. This information is transmitted to a signal source with an EDID and a signal with the optimum a number of sound channel is sent. The EDID is also used for the connection with a display unit and the speaker connection with which the display unit is provided uniquely. For example, a sound through the 7.1 channel is easily reproduced using the speaker of the display unit in the channel of the front speaker. | 2014-12-11 |
