摘要： An apparatus (1001), system (1000) and method (800-900) are provided for improving the de-encapsulation of sections from Multi Protocol Encapsulation (MPE) (151) and Multi Protocol Encapsulation-Forward Error Correction (MPE-FEC) (152) Sections in a DVB-H transport stream. DVB-H is a standard for broadcasting services to hand-helds. Its difference from DVB-T, C, and S that is relevant for this invention is the presence of an additional layer of Forward Error Correction (FEC). Instead of restoring only correctly received sections (151) (152) the present invention also restores fragments of sections (151) (152) by using both Transport Stream packet headers (301. i.1) and section headers (151.1). As a result, entire sections (800-900) may not be erased (which can amount to up to 4080 bytes) whenever one or more fragments are received incorrectly, but only the incorrectly received fragments (which can be each up to 184 bytes) are erased. This leads to a more efficient use of the additional layer of Forward Error Correction (FEC) information.

摘要： In transmission systems using digital video broadcasting standards for handheld terminals data is transmitted in bursts. Due to the restricted computing time, buffering of one or more bursts is necessary. The invention provides a memory optimalization for consecutive burst support. Thereby, a cyclic or non-cyclic memory model for a memory unit (19) of the device (1) for receiving bursts is provided.

摘要： In transmission systems using digital video broadcasting standards for handheld terminals data is transmitted in bursts. A decoder unit (25) is provided to correct errors in the data. An error amount determination unit (30) is provided to determine, when the amount of error correction data for error correction is sufficient for a successful error correction. Therefore, in the average, power consumption of the device (1) may be reduced by an early receiver front-end switch-off.

摘要： This invention describes a system and method for assigning four levels of priority to erasures and promoting/degrading erasures by confining the number of locations to which erasures are assigned using decoder information from a preceding RS decoder and a CRC. The preceding decoder produces soft-erasure information based on blocks of 184 bytes, while the CRC can cover blocks of sizes up to 4,080 bytes whereas the invention combines the CRC with information of the preceding decoder erasures such that the combination is assigned in multiples of 184 bytes.

摘要： A trick play information stream is generated from a normal play information stream, so that they can be recorded together as a composite information stream on the record carrier, such that upon reproduction in a trick play reproduction mode, an information signal of sufficient quality, e.g., as regards visibility, can be obtained. GOPs are generated, each GOP including an I-frame retrieved from the original normal play information stream, and one or more so-called ‘empty P frames’. Another aspect is the requirement of generating GOPs for the trick play information stream that have a constant bitcost per GOP. Again, another aspect lies in the retrieval of the I-frame for the trick play information stream from the normal play information. More specifically, an I-frame is generated by retrieving, from an I-frame included in the normal play information, the DC coefficient of the I-frame and a number of AC coefficients from that I frame, and generating the I-frame for the trick play information stream therefrom. More specifically, the number of AC coefficients for an I-frame of the trick play information signal depends on the difference between the DC coefficients of two subsequent I-frames in the normal play information from which the I-frame to be generated and the just previously generated I-frame for the trick play information signal have been derived.
