Abstract: A network device, a speed test method and a system thereof are provided. The system provides a speed test server that allows the network device to initiate a speed test by issuing a test request with information of a bandwidth at an end of the network device to the speed test server. In an aspect, the system also provides a dispatch server that selects one available speed test server for performing the speed test method. In the speed test method, the speed test server transmits test packets with a first identifier to the network device and the network device calculates a downstream transmission rate based on the received test packets. The network device transmits test packets with a second identifier to the speed test server, and the speed test server calculates an upstream transmission rate based on the received test packets.

Abstract: The present invention provides a camera system and the operating method thereof, wherein the camera system transmits a digital token via sound waves and uses the digital token for device pairing, authorizing, or authenticating. The camera system comprises a transmitting device, for converting the digital token to an acoustic signal, and a camera device, for converting the acoustic signal to the digital signal.

Abstract: The present invention relates to a camera device, wherein the camera device comprising a base with a fillister; a body with a spherical unit and a neck; and a camera configured onto the body. The spherical unit fits the fillister to form a joint allowing a wide range of rotation in all direction. The base further comprises a first fixing unit and a second fixing unit. Therefore, the camera device is able to be easily mounted onto a targeted surface; and, the camera field of view is able to be rapidly optimized toward a specific direction.

Abstract: A system of an internet interactive service and operating method thereof is disclosed. A network host is to transmit an audio watermark not only to connect with multiple devices but also to set the multiple devices as a specific group. The invention comprises following steps: connecting at least one multimedia device with the network host, transmitting the audio watermark which may comprise certification from the network host to the at least one multimedia device, the at least one multimedia device broadcasting the audio watermark, the at least one electronic device receiving the audio watermark and afterward transmitting the audio watermark or the certification to the network host, the network host recognizing the audio watermark or the certification and afterward setting the at least one multimedia device and the at least one electronic device as the specific group, transmitting at least one datum from the network host to the specific group.

Abstract: A characteristic karaoke video-on-demand (VOD) system with a reference index database is provided. According to the reference index database as well as a song request signal inputted by a user, the characteristic karaoke VOD system is able to recommend at least one artist or at least one song to the user to enhance convenience and functionality offered by the characteristic karaoke VOD system.

Abstract: A situation command system including a multimedia apparatus and a server is provided. The multimedia device and the server are connected via a network system. The multimedia apparatus, including a microprocessor, a memory device, a multimedia file input device, a network interface, an audio/video body-sensing input device, an audio/video body-sensing output device and a control device, presents a multimedia effect of a file to a user. The server, including a central processing system, a storage system, a communication system and a recognition system, accesses the file and determines whether the file satisfies a trigger condition to selectively output a special effect. When the file satisfies the trigger condition, the multimedia apparatus further superimposes the special effect to the file and presents the file together with the special effect to the user to provide a situation simulation effect.

Abstract: The invention relates to a multimedia apparatus and more particularly to a multimedia apparatus capable of providing karaoke service through Internet servers or other external devices. The invention provides operating interfaces that are compatible to individual hardware, internet server, and mode of instruction input. The invention identifies multimedia files in external storages and further offers an offline karaoke service.

Abstract: A container assembly includes exterior and interior containers, a cover, driving and driven members, and a transmission member. The cover is connected pivotally to the exterior container so as to move towards or away from a top opening of the exterior container. The driving member rotates along with the cover. The transmission member is pivotally connected to the driving and driven members. The driven member turns upward and lifts the interior container when the cover is moved away from the top opening.

Abstract: A method for determining a search pattern for use in fractional motion estimation for video compression includes selecting a search center within a current macroblock; selecting a plurality of search points forming a half-pel search pattern surrounding the search center, and further selecting another search point at the search center; calculating a cost value for each search point according to a first cost function; and selecting a quarter-pel search pattern according to the cost values of at least two search points, the half-pel search pattern and the quarter-pel search pattern forming the search pattern. The search pattern is used in a matching process to determine a similarity of the current macroblock to a reference macroblock in a video undergoing compression.
