| An apparatus and a method for improving a channel change speed in a digital broadcasting receiving terminal are provided to greatly reduce time for changing a current channel to a channel selected by a user in the digital broadcasting receiving terminal which receives digital broadcasting data of a DVB-H(Digital Video Broadcasting-Handheld) broadcasting type. A digital broadcasting receiving unit(210) receives broadcasting data from at least one of a predetermined reference channel and the other channels different from the reference channel, and extracts start time point information about a start time point when the reception of the broadcasting data of the corresponding channels is started from the received broadcasting data. A timer(218) extracts a time value by a time point when the broadcasting data of the reference channel are received and a time value by a time point when the broadcasting data of one of the other channels per the respective other channels are received. A control unit(200) controls the digital broadcasting receiving unit(210), extracts start time point information of the reference channel and the other channels, receives the broadcasting data of the respective channels according to the start time point information of the reference channel and start time point information of the other channels, and stores the time values extracted through the timer(218) as time offset values of the corresponding other channels. | ||||||

| Disclosed is a method for ensuring the integrity of a container to be transmitted to a Digital Video Broadcasting-Handheld (DVB-H) terminal. A DVB-H server divides a container in which data required to deliver broadcasting information is included into one or more sections, extracts a Cycle Redundancy Check (CRC) value related to data of each section, and then creates profile information of the container. The created profile information of the container is used to check the integrity of the container, and is transmitted following the addition of the created profile information to a header part of the container. Hence, the terminal compares data of an actually received container with data of a container which has to be received on the basis of the profile information related to the container, and determines if the data included in the container is lost. | ||||||

| Provided is a method and apparatus for decoding a Multi-Protocol Encapsulation Forward Error Correction (MPE-FEC) frame in a Digital Video Broadcasting-Handheld (DVB-H) system. Packet Identifier (PID) filtering is performed on a Transport Stream (TS) packet received via a wireless network to detect a TS packet, and a table ID is detected from header information of the section data to identify the section data type. If the section data is an MPE section, frame buffering is performed. If there is a remaining portion in the data region after storage of an IP datagram of the last MPE section, zero-padding is performed on the remaining portion. If the section data is an MPE-FEC section, frame buffering is performed on parity data extracted from the MPE-FEC section. | ||||||

| 196 | SELF-ADAPTIVE FREQUENCY INTERPOLATOR FOR USE IN A MULTI-CARRIER RECEIVER | US12733455 | 2008-09-19 | US20110129035A1 | 2011-06-02 | Peng Liu; Li Zou |
| A Digital Video Broadcasting-Terrestrial/Handheld (DVB-T/H) receiver comprises a controller and a frequency interpolator for use in estimating channel state information (CSI) information of a received signal by frequency interpolation. The controller determines a multi-path delay (Tmax) for the received signal and adjusts the bandwidth of the frequency interpolator as a function of the determined multi-path delay. For example, when the multi-path delay is small, the bandwidth of the frequency interpolator is adjusted to be smaller than the bandwidth of the frequency interpolator when the multi-path delay is large. In addition, the controller may also change the coefficients of the frequency interpolator such that different word lengths are used for the coefficients as a function of the determined multi-path delay. | ||||||

| A Digital Video Broadcasting-Handheld (DVB-H) system comprises a head-end and at least one receiver. The head-end uses the File Delivery over Unidirectional Transport (FLUTE) protocol for transmitting an electronic service guide (ESG) and content to the receiver. The receiver determines a time delay for receiving content as a function of a value of a PublishedStartTime parameter from the ESG and the actual time the receiver receives the content. Using this time delay, the receiver forms a time estimate for receiving selected content as a function of a value of a PublishedStartTime parameter from the ESG for the selected content and the determined time delay. The receiver then performs power, management such that during those intervals of time that the receiver is not expected to receive the selected content the receiver can reduce power. | ||||||
