摘要： Systems and methods for processing multimedia information are disclosed and may include adjusting a decoding rate for a received transport stream based on a ratio of a plurality of accumulated program clock reference (PCR) values and a corresponding plurality of accumulated system time clock (STC) values. The received transport stream may include a plurality of audio samples. A portion of the plurality of audio samples may be decoded based on the adjusted decoding rate. The plurality of PCR values within the received transport stream may be detected and stored within on-chip memory. The plurality of STC values may be generated based on incrementing a counter during decoding of the received transport stream. The generated plurality of STC values may be stored within on-chip memory. A first difference between a current PCR value and a subsequent PCR value may be calculated.

摘要： Embodiments of the present invention significantly decrease the processing requirements as well as the cost of digital television receivers. In an embodiment, processing requirements of both hardware and software components in digital television receivers are lowered by generating the channel map without regard to channel map information present in a Virtual Channel Table (VCT). In another embodiment, significant recurring portions of an ATSC signal can be neglected with no processing power, cost, and time spent thereon. In another embodiment, processing typically used to process channel map information contained in the VCT portion of the ATSC signal is freed and may instead be used to process other information, thereby enabling further enhancements and features in digital television services.
摘要翻译：本发明的实施例显着地降低了数字电视接收机的处理要求以及成本。在一个实施例中，通过在不考虑存在于虚拟频道表（VCT）中的频道映射信息的情况下生成频道映射来降低数字电视接收机中的硬件和软件组件的处理要求。在另一个实施例中，可以忽略ATSC信号的有效重复部分，而不需要处理能力，成本和花费的时间。在另一个实施例中，通常用于处理包含在ATSC信号的VCT部分中的频道映射信息的处理被释放，并且可以替代地用于处理其他信息，从而实现数字电视服务中的进一步增强和特征。

摘要： A STB resource sharing (RS) group of a home network comprises a plurality of STBs. In the STB RS group, a STB communicates with one or more other STBs to mutually share available device resources comprising hardware and software resources, and/or capabilities. The STB functions as an elected master (EM) or a STB RS client in the STB RS group. As an EM, the STB receives advertisements from other STBs to determine available resources. The determined available resources are announced to other STBs in the STB RS group. The STB manages the use of the determined available resources according to resource sharing requests received from other STBs. As a STB RS client, the STB advertises inherent resources to an EM of the STB RS group. The STB receives announcements from the EM for available resources in the STB RS group. The STB shares its available resources, accordingly.

摘要： A home network (HN) server is configured to terminate IP-based multicast packets received from, for example, an external IPTV service distribution network and record in storage of the HN server. The HN server transmits the terminated multicast packets to a plurality of HN clients based on corresponding link quality between each of the HN clients and the HN server. A transmission mode and local IP protocols are determined based on corresponding link quality for each of the HN clients. The recorded multicast packets are reformatted based on the determined local IP protocols and transmitted in the determined transmission mode to corresponding HN clients. The HN server acquires expected recorded multicast packets when not available in its storage from peer HN servers and reformats the acquired expected recorded multicast packets based on the determined local IP protocols for transmission. Packet transmission are suspended or resumed according to a client service pause.
