Patent number: 7835758Abstract: A receiver terminal, like a mobile apparatus or a mobile phone, downloads a multimedia message from a message center via a network. An arrival notification is first transmitted from the message center to the receiver terminal. In the notification, a length of the multimedia message is identified. The receiver terminal, however, checks a portion of the multimedia message downloaded to ensure the actual size indicated by the portion of the multimedia message is consistent with the length identified by the notification. If there is problem, users are inquired for confirmation to determine whether to continue downloading the rest portion of the multimedia message.Type: GrantFiled: November 4, 2005Date of Patent: November 16, 2010Assignee: Mediatek Inc.Inventors: Guan-Hua Tu, Jyh-Chun Wang

Publication number: 20070266099Abstract: A method and a mobile unit for transmitting and for receiving contact information are provided. A memory for transmission stores a profile datum and a multimedia datum of the contact information. An encoder retrieves the profile datum and the multimedia datum from the memory, encodes the profile datum in a first format into a first file, and encodes the multimedia datum in a second format into a second file. A transmission unit transmits both of the first file and the second file. A receiving unit receives a first file and a second file. A processor determines whether the first file and the second file comprise the profile datum and the multimedia datum, and generates a signal if yes. A decoder decodes the profile datum in the first format and decodes the multimedia datum in the second format in response to the signal. A memory for receiving stores the decoded profile datum in a first location based on the first format and the decoded multimedia datum in a second location based on the second format.Type: ApplicationFiled: March 28, 2006Publication date: November 15, 2007Inventors: Jyh-Chun Wang, Guan-Hua Tu
