The open cable TV application platform (opencable application Platform,ocap) is a platform for the cable television industry. Targeting set-top boxes and TVs, OCAP provides a standard, hardware-independent basis for interactive applications that enhance the consumer's cable TV experience. OCAP consumer-oriented name is the Tru2way;tru2way certificate including many well-known companies on the consumer electronics market. The OCAP specification is formulated by the

Codec that uses the entire 4 kHz band, while most standard Low Bit Rate Codec uses from 300Hz3400Hz frequency band. This has a significant impact on sound quality. In addition, the spectrum characteristics of ilbc voice encoding accurately simulate the characteristics of the original signal, and its speech rate is lower than the standard bit rate.Codec is more natural and clear. All in all, the ilbc algorithm implements cutting-edge fixed bit rate encoding for the packet network and achieves an

important files and directories. An important position is ocaproot, which is the root of the OCAP implementation source code. It is the root of a rather complex tree that supports building code on different hosts, targeting multiple targets. For example, you can build OCAP implementations on a single Linux computer for a particular set-top box. Alternatively, you can build on the OCAP RI platform on a Windows computer. The actual value of the ocaproot depends on where the OCAP RI binaries are

for this decoder. CableLabs is used to specify the PacketCable Audio/Video Decoder specifications of the multimedia terminal adapter and media gate as necessary. With this decoder, the necessary VoWLAN voice quality is easier to implement, and it can also solve the latency and Jitter Caused by the Internet. Therefore, it is particularly suitable for non-synchronous open systems such as 802.11. Since the decoder is so flexible, why should we develop c

-generation Decoder One of the ways to improve the existing infrastructure of 802.11 is to use a newer voice decoder developed for Internet applications. These decoders greatly simplify VoWLAN design. The inefficient Internet telephone environment facilitates decoder development and achieves sound voice quality at an extremely low speed. For example, the iLBC decoder, the core of the popular Skype network telephone system, provides features equivalent to the high-end ITUG.729 decoder. The ITU d

NGN's streaming media service not only provides video stream services, such as broadcast and television and VoD, but also integrates voice, data, and video services for common and commercial users, for example, Caller-IDonTV ). At present, the NGNRelease1 architecture established by ITU-TFGNGN-FRA includes the IP Multimedia Service Section (including the simulation service of PSTN/ISDN) and the simulation service section of PSTN/ISDN, however, there is no in-depth research on the stream media an

mobile phones and other voice devices to take advantage of existing WLAN infrastructures. Next-generation decoder One way to improve the existing 802.11 infrastructure is to leverage newer speech decoders developed for Internet applications. These decoders greatly simplify the design of Vowlan. Inefficient Internet telephony environment, enabling the development of decoder, can be very low speed to achieve good speech quality. For example: The popular Skype network telephony system core ILBC
