摘要:
A system and method for video quality assessment includes utilizing codec auxiliary information related to the encoding and decoding process to enhance performance of picture quality assessment. In a video transmission system, video quality assessment can be accurately performed in real time with reduced computational load upon the client. In particular, the server performs first picture quality assessment and sends the assessment result to the client, and the client performs second picture quality assessment only when a transmission error occurs to reduce the computational load on the client.
摘要:
A portable terminal having a mass storage secondary memory and a method for the portable terminal, wherein high-speed data transfer between the mass storage secondary memory and an external apparatus is supported in a multitasking manner are provided. Between the portable terminal having the mass storage secondary memory and the external apparatus, the method of setting a data transfer path comprises setting a first data path so as to permit the mass storage secondary memory to operate according to internal control of the portable terminal, determining whether the portable terminal is connected with the external apparatus through a USB switcher, and if the portable terminal is connected with the external apparatus, determining whether a set command is input to set the mass storage secondary memory as a portable disk of the external apparatus. If the set command is input, the first data path is blocked, and a second data path is set to permit the mass storage secondary memory to operate according to external control exercised by the external apparatus. The portable terminal can perform a task operation in a multitasking manner independently of the ongoing data transfer between the mass storage secondary memory and the external apparatus, and high-speed data transfer between the mass storage secondary memory and the external apparatus is possible through a high-speed USB interface.
