Patent number: 7956933Abstract: In a tuner circuit, an automatic gain control circuit generates an RF-AGC voltage for automatically controlling a gain of an RF-AGC amplifier in accordance with a level of a signal output from an IF amplifier. An emitter follower circuit includes a transistor for current amplification, and varies a drive current of the transistor in accordance with the RF-AGC voltage. Thus, when an interference signal is at a high level, the drive current of the transistor becomes large. Therefore, distortion performance of the emitter follower circuit is improved. On the other hand, in a normal state where the interference signal is at a low level, the drive current of the transistor fails to become large. Therefore, low power consumption is achieved.Type: GrantFiled: September 5, 2006Date of Patent: June 7, 2011Assignee: Sharp Kabushiki KaishaInventor: Kohji Ohiwa

Patent number: 7958535Abstract: A uniform resource indicator (URI) pointer system and method are provided for retrieving MPEG-4 data pointers in an MPEG-2 TS. The method comprises: receiving an MPEG-2 TS; locating a URI in the TS; in response to the URI, accessing an address; in response to accessing the address, retrieving MPEG-4 resources; and, decoding the MPEG-4 resources. The URI pointer can be a local cache address, a Web protocol identifier (such as http), and/or a local identifier (lid). In some aspects, the MPEG-2 TS may include MPEG-4 resources organized in an Object Carousal (OC) transport protocol. Then, lid URIs provide a binding name and access scheme to the objects in the OC. For example, a lid URI may be embedded in an Initial Object Descriptor (IOD) to locate resources in the OC such as a binary format for scenes (BIFS) scene description stream and/or an object descriptor stream.Type: GrantFiled: September 25, 2003Date of Patent: June 7, 2011Assignee: Sharp Laboratories of America, Inc.Inventor: Kai-Chieh Liang
